Abstract:[Objective] To search the independent risk factors related to nerve injury in lumbar interbody fusion, and to provide a refer- ence for the prevention of the neurological complications. [Methods] A retrospective study was conducted on 418 patients who received pos- terior lumbar interbody fusion (PLIF) or transforaminal lumbar interbody fusion (TLIF) for lumbar degenerative diseases (LDDs) in our hos- pital from September 2015 to June 2020. The patients were divided into the impaired group and the non-impaired group according to wheth- er neurological damage was found after surgery. The independent risk factors of postoperative nerve damage were analyzed by univariate comparison and multi-factor binary logistic regression. [Results] Among the 418 patients, 28 patients (6.7%) had aggravated neurological injury symptoms after surgery, while the remaining 390 patients (93.3%) had no nerve damage symptoms occurred within 24 hours after op- eration. In term of univariate comparison, the patients in the impaired group had significantly higher BMI, significantly longer disease course, significantly higher rate of preoperative diagnosis of lumbar spinal stenosis (LSS) or degenerative lumbar spondylolisthesis (DLS), significantly heavier degree of slippage, significantly higher percentage of revision surgery, and significantly higher ratio of PLIF surgery compared with those in the non- impaired group (P＜0.05). However, there were no statistically significant differences between the two groups regarding gender, age, number of slip segments, ASA grade, whether comorbidities with hypertension, diabetes, coronary heart dis- ease, as well as operation time, intraoperative blood loss, catheter indwelling time, hemoglobin and albumin level before and after surgery (P＞0.05). As results of logistic regression, the course of disease (OR=1.322, P＜0.001), BMI (OR=3.325, P=0.003), PLIF surgery (OR= 10.017, P=0.002), combined lumbar spondylolisthesis (OR=4.572, P=0.006), revision surgery (OR=6.182, P=0.008) were the independent risk factor related to neurological complications in lumbar interbody fusion. [Conclusion] The patients with long course of disease, obesity,PLIF surgery, lumbar spondylolisthesis and revision surgery are at higher risk of postoperative neurological complications, and targeted measures should be taken to reduce the occurrence of nerve injury.

Abstract:[Objective] To compare the clinical efficacy of the bridge-link fixation combined with Nice knot (BLFNK) versus plate for midshaft clavicular fractures. [Methods] A retrospective study was conducted on 62 patients who received open reduction and internal fixa- tion (ORIF) for midshaft clavicle fractures in our departments from January 2019 to June 2021. According to the results of doctor-patient communication, 28 patients were treated with BLFNK, while the remaining 34 patients had fractures fixed with plate. The documents re- garding to perioperative period, follow-up and imaging were compared between the two groups. [Results] All the patients in both groups had ORIF performed smoothly with no serious complications such as vascular and nerve injury. The BLFNK group proved significantly su- perior to the plate group in terms of operation time, intraoperative blood loss and time to return active activity (P＜0.05), although there were no significant differences in incision length, incision healing grade and hospital stay between the two groups (P＞0.05). The VAS scores for pain during the early postoperative period were significantly reduced over time in both groups (P＜0.05), which was not significantly differ- ent between the two groups at corresponding time points (P＞0.05). All of them in both groups were followed up for more than 12 months, and the BLFNK group resumed full weight-bearing activity significantly earlier than the plate group (P＜0.05). The Constant-Murley scores significantly increased in both groups over time after surgery (P＜0.05), which was not significantly different between the two groups at corre- sponding time points (P＞0.05). Radiographically, the BLFNK group got better fracture reduction quality than the plate group regardless of the fact that there was no statistical difference between the two groups (P＞0.05). In addition, there was no significant difference in fracture healing time between the two groups (P＞0.05). [Conclusion] The bridge-link fixation system combined with Nice knot achieves better clini- cal outcomes than the traditional plate internal fixation for midshaft clavicle fractures.

Abstract:[Objective] To compare the clinical efficacy of unilateral external fixator versus intramedullary nail for spiral tibial shaft fractures. [Methods] A retrospective study was done on 64 patients who had surgical treatment for spiral tibial shaft fractures in our hospi- tal from June 2015 to December 2020. According to the results of preoperative doctor-patient communication, 32 patients had the fractures fixed with unilateral external fixator (the EF group), while the other 32 patients were fixed with intramedullary nail (the IN group). The peri- operative period, follow-up and imaging data were compared between the two groups. [Results] All the 64 patients were successfully operat- ed on without serious complications. The EF group proved significantly superior to the IN group in terms of operative time, incision length, intraoperative blood loss, postoperative walking time and hospital stay (P＜0.05), despite of no significant difference in the number of intra- operative fluoroscopy between the two groups (P＞0.05). All the 64 patients were followed up for more than 12 months, and the EF group re- sumed full weight-bearing activity of the affected limb significantly earlier than the IN group (P＜0.05). The VAS scores decreased signifi- cantly (P＜0.05), while the AOFAS score and ankle plantar-dorsiflexion range of motion (ROM) increased significantly in both groups over time (P＜0.05). At any corresponding time points there were no significant differences in AOFAS score and ROM between the two groups (P＞ 0.05). The EF group was marked significantly higher VAS score than the IN group 3 months after surgery (P＜0.05), whereas which became not significant different between the two groups at the latest follow-up (P＞0.05). Radiographically, there were no significant differences in the quality of fracture reduction and fracture healing time between the two groups (P＞0.05). [Conclusion] Both unilateral external fixator and intramedullary nail do achieve good clinical outcomes for spiral tibial shaft fractures. In comparison, unilateral external fixator is less invasive and allows patients to actively move early.

Abstract:[Objective] To compare the clinical effects of open reduction and internal fixation (ORIF) through tarsal sinus approach (TSA) versus L-shaped approach (LSA) for Sanders type Ⅱ and Ⅲ calcaneal fractures. [Methods] A retrospective study was conducted on 80 patients who underwent ORIF for calcaneal fractures in our department from January 2018 to October 2020. According to doctor-patient communication, 38 patients had ORIF performed by TSA, while the remaining 42 patients were by LSA. The perioperative, follow-up and imaging data were compared between the two groups. [Results] All the patients in both groups were operated on successfully without seri- ous complications such as neurovascular injuries. The TSA group proved significantly superior to LSA in terms of incision length, intraoper- ative blood loss, incision healing grade, walking time on the ground and hospital stay (P＜0.05). All the patients in both groups were fol- lowed up for (22.7±7.6) months on an average, and the TSA group resumed full weight-bearing activity significantly earlier than the LSA group (P＜0.05). The VAS score significantly decreased (P＜0.05), while the AOFAS score, varus and valgus range of motion of the foot sig- nificantly increased (P＜0.05) in both groups over time. At 1 month, 6 months postoperatively and the latest follow-up, the TSA group was significantly superior to the LSA group in terms of VAS and AOFAS scores (P＜0.05). Radiographically, the Bohler angle and Gissane an- gle were significantly improved postoperatively compared with those preoperatively in both groups (P＜0.05), whereas which were not statisti- cally significant between the two groups at any corresponding time points (P＞0.05). [Conclusion] The tarsal sinus approach for open reduc- tion and internal fixation of Sanders type Ⅱ and Ⅲ calcaneal fractures has the advantages of minimizing surgical trauma and improving functional recovery over the traditional L-shaped approach.

Abstract:[Objective] To compare the clinical efficacy of tarsal sinus approach (TSA) versus lateral L- shaped approach (LLA) for open reduction and internal fixation (ORIF) of Sanders Ⅱ and Ⅲ calcaneal fractures. [Methods] A retrospective study was done on 40 pa- tients (44 feet) who received ORIF for Sanders type Ⅱ and Ⅲ calcaneal fractures from July 2018 to August 2021. According to the results of preoperative doctor-patient communication, 21 feet received ORIF with headless screws and minimally invasive locking plate through the TSA, while the remaining 23 feet were treated with ORIF by anatomic locking plate through traditional LLA. The perioperative period, follow- up and imaging documents were compared between the two groups. [Results] The TSA group proved significantly superior to the LLA group in terms of operation time, incision length, intraoperative blood loss and hospital stay (P＜0.05), regardless of the fact that there were no statistically significant differences in terms of intraoperative fluoroscopy times and postoperative walking time between the two groups (P＞0.05). All 40 patients were followed up for more than 12 months without a significant difference in the time to resume fullweight-bearing activities between the two groups (P＞0.05). The VAS scores decreased significantly (P＜0.05), while the AOFAS ankle-hind- foot score and foot inversion-eversion range of motion (ROM) increased significantly in both groups over time postoperatively (P＜0.05). The TSA group was significantly better than the LLA group in VAS scores 1 day after surgery (P＜0.05), whereas which became not significant different between the two groups at 6 months and the latest follow-up (P＞0.05). In addition, there were no significant differences in AOFAS ankle-hindfoot score and inversion- eversion ROM between the two groups at any corresponding time points (P＞0.05). Regarding to imag- ing evaluation, the Gissane angle, Bohler angle, calcaneal length and width significantly improved in both groups immediately after surgery and at the latest follow-up compared with those preoperatively (P＜0.05), whereas which proved not statistically significant between the two groups at any corresponding time points (P＞0.05). [Conclusion] The ORIF with headless screw and minimally invasive locking plate through tarsal sinus approach has the advantages of shortening operation time, reducing intraoperative bleeding, incision length and compli- cations over the traditional counterpart with anatomic locking plate through the lateral L-shaped approach for treatment of Sanders type Ⅱ and Ⅲ calcaneal fractures

Abstract:[Objective] To compare the clinical outcomes of microfracture combined with platelet-rich plasma (PRP) versus microfrac- ture only for treatment of cartilage lesions. [Methods] The data bases, such as Cochrane Library, PubMed, Web of science, EMBASE, CNKI, Wanfang Data and CBM Data were searched for papers comparing clinical outcomes of microfracture combined with PRP versus microfrac- ture only for cartilage lesions from the setting up to December 2021. After literature screening, quality assessment, and data extraction were conducted to meet the inclusion and exclusion criteria, Rev-Man 5.3 was used to perform the meta-analysis of the parameters related to clinical consequences. [Results] A total of 9 articles were enrolled in this study, involving 307 patients with cartilage lesions, including 158 cases in the PRP group and 149 cases in the non-PRP group. As results of the meta-analysis, the PRP group proved significantly superior to the non- PRP group in term of VAS scores at 6, 12 and 24 months after surgery (P＜0.001; P＜0.001; P=0.11). The PRP group proved sig- nificantly superior to the non- PRP group in term of IKDC scores at 12 and 24 months after surgery (P＜0.001; P＜0.001). The PRP group proved significantly superior to the non- PRP group in AOFAS scores at the final follow-up lasted for 21.4 months on a mean (P＜0.001). [Conclusion] Microfracture combined with PRP does further relieve joint pain and improve joint function, which plays a role in enhancing the therapeutic effect of microfracture.

Abstract:Malunion is a common complication after distal radius fracture, which involves the radiocarpal joint, ulnocarpal joint, and distal radioulnar joint. This malunion does have a certain impact on the biomechanics and clinical prognosis of the distal radioulnar joint with clinical manifestations such as pain, limited rotation of the forearm, instability of the distal radioulnar joint and distal radioulnar arthri- tis. In the previous literature on the malunion of distal radius fractures at home and abroad, many scholars have focused on the radiocarpal joint and the ulnocarpal joint, while there is a rare research on the distal radioulnar joint. This article reviews the recent research progress on the effects of distal radius fracture malunion on the distal radioulnar joint, to provide a reference for clinical prevention, treatment, and further research.

Abstract:Intraosseous epidermoid cyst (IEC) is a rare, non-neoplastic benign lesion with the most common site involving the distal phalanx. Intraosseous epidermoid cyst is prone to be confused with endophytic chondroma in imaging. In this paper, we reported a case of epidermoid cyst of lunate misdiagnosed as endophytic chondroma in the orthopedic department of our hospital. We used lesion curettage, anhydrous alcohol inactivation and collagen sponge filling to treat the patient. In addition, a thorough literature review was done to summa- rize the clinical features, diagnostic criteria and treatment principles of IEC to provide reference for diagnosis and treatment of epidermoid cyst of lunate.

Abstract:Hippo signaling pathway mediates signal transmission inside and outside cells, which regulates the process of cell prolifera- tion, differentiation and apoptosis, and playes role in bone metabolism, lipid metabolism and angiogenesis. Therefore, this pathway may be of great significance in the pathogenesis of non-traumatic femoral head necrosis. This paper mainly discusses the mechanism of Hippo path- way related protein structure and function in bone metabolism and lipid metabolism, and looks for its mechanism in NONFH to provide a new clinical research target for NONFH.

Abstract:In recent years, with the development of orthotics in the direction of light weight and comfort, the elastic fabrics have been used more and more in this field. Compared with other traditional soft materials, the elastic fabric has high air permeability, thus creating a moisture free environment, reducing the tissue ulceration and necrosis caused by long-term pressure and hypoxia of skin and underlying tis- sues, improving comfort and enhancing compliance of patients wearing orthotics. This article reviews the latest application progress of elas- tic fabrics in the field of individualized orthotics, covering elastic fabric types, fibers and yarns, fabric structures, material properties, pro- cessing technique, specific applications and future developments, providing a reference for clinical applications.

Abstract:[Objective] To explore the role and potential mechanism of human umbilical cord mesenchymal stem cell-exosomes (hUC- MSC-exos) in the prevention and treatment of steroid-induced femoral head necrosis in rats. [Methods] A total of 36 7-week-old male Sprague-Dawley rats were randomly divided into 3 groups, with 12 rats in each group. The animals in the blank control group were given 0.9% normal saline intravenously, those in the model group was given lipopolysaccharide (LPS) and methylprednisolone (MPS) intravenous- ly to create the femoral head necrosis model, while those in the exosome group received hUCMSC-Exos intravenously on the basis of the drugs given in the model group. The rats were sacrificed 28 days later, and the femoral heads were harvested for histological observation and micro CT examination. [Results] Transmission electron microscopy and Western blot showed that the extracts isolated was consistent with the basic characteristics of exos. The empty rate of bone lacunae in three groups showed by HE staining was ranked up-down in order of the model group ＞ the exosome group ＞ the blank control group, with statistically significant differences between them (P＜0.05). Apopto- sis rate of osteoblasts revealed by Tunel staining was also ranged up-down as the model group ＞ the exosome group ＞ the blank control group, which were statistically significant between them (P＜0.05). Compared with the blank control group, the BV/TV, Tb.Th and Tb.N sig- nificantly decreased (P＜0.05), while Tb.Sp significantly increased in the model group (P＜0.05). Compared with the model group, the BV/ TV, Tb.Th and Tb.N significantly increased (P＜0.05), while Tb.Sp significantly decreased in the exosome group (P＜0.05). [Conclusion] The exosomes obtained from human umbilical cord mesenchymal stem cells does prevent steroid-induced femoral head necrosis in rats by inhibiting osteoblast apoptosis in this study.

Abstract:[Objective] To introduce the surgical technique and preliminary clinical outcomes of 3D printed sliding titanium plate for fixation of unstable atlas fracture. [Methods] From April 2018 to April 2021, 9 patients received open reduction and internal fixation with 3D printed personalized sliding titanium plate for unstable atlas fractures. As thin-layer CT scan of the upper cervical vertebra was per- formed before surgery, the 3D model of upper cervical spine was reconstructed using the Mimics software, and then the data captured by the Geomagic Studio software to design the C1 posterior sliding titanium plate, finally the real personalized sliding plate was made by the 3D printer. The posterior cervical incision was made under general anesthesia to expose the posterior arch of C1, establish the vertebral arch screw path. The 3D printed sliding titanium plate was placed to fit the posterior arch, and then insert the screw in proper length. As adjust- ing the plate sliding, the fracture reduction and compressive fixation were finished. [Results] All patients were successfully operated on without serious complications, whereas with operation time of (66.5±7.3)min and intraoperative blood loss of (92.5±27.3)ml, and followed up for 12~18 months. Compared with those preoperatively, the VAS scores [(7.1±1.6), (1.8±1.0), P＜0.05], JOA score [(8.7±6.0), (16.3±4.7), P＜0.05] improved significantly at the latest follow-up. Radiographically, all patients had screw placed properly on images, without screw broken through the bone cortex, while with satisfactory fracture reduction. Up to the last follow-up, all patients got fractures healing without loosening or fracture of the implants. [Conclusion] The 3D printed titanium sliding plate for internal fixation of unstable atlas fracture is feasible, safe and efficient.

Abstract:[Objective] To introduce the surgical technique and preliminary clinical results of V-shaped double-bundle anatomical re- construction of the anterior talofibular ligament (ATFL) by using a half peroneal brevis tendon. [Methods] A total of 23 patients received abovementioned surgical treatment for chronic lateral ankle instability. Over the ATFL trace an arc incision was made to expose the liga- ment remnants, which proved unproper to be sutured directly. The bone tunnels were created individually on the upper and lower border of the anatomic fibular footprint, as well as the talar anatomic footprint. A longitudinal half peroneus brevis tendon was obtained by a tendon harvester, and prepared to V-shaped graft. Subsequently, the tendon graft was respectively introduced into the superior fibular tunnel, the inferior fibular tunnel and the talar tunnel, and tighten and fixed with interference screws or suture anchors to reconstruct the ATFL in dou- ble bundles and V- shape. [Results] All patients were successfully operated on without serious complications, and were followed up for more than 12 months. The AOFAS score significantly increased from (46.7±9.5) before operation to (91.6±2.8) 12 months after operation (P＜ 0.05), KAF score significantly increased from (49.4±1.9) to (90.8±2.7) (P＜0.05), whereas the VAS pain score significantly decreased from (5.8±0.9) before surgery to (1.7±0.9) 12 months after surgery (P＜0.05). At the latest follow-up, all the patients got negative ADT and TTT tests, had no ankle pain, and got considerably improved daily function and joint movement, stability and hindfoot alignment compared with those preoperatively. [Conclusion] This V-shaped double-bundle ATFL anatomical reconstruction with longitudinal half peroneus brevis tendon dose restore the biomechanical function of the ankle and achieve sound clinical outcome.

Abstract:[Objective] To introduce the surgical technique and preliminary clinical results of modified percutaneous vertebroplasty (PVP) or percutaneous kyphoplasty (PKP) to improve the safety of bone cement injection. [Methods] From January 2015 to January 2020, 199 patients received the modified PVP/PKP for osteoporotic vertebral compression fractures in our departments. The innovation point in- cluded the integrated application of target puncture and catheterization in the fracture area, the lateral push rod assisted bone cement target injection, and pedicle trailing anchoring. The diffusion filling and leakage of bone cement were observed by intraoperative fluoroscopy, post- operative X-ray and CT. [Results] All the patients had operation performed smoothly, with operation time for single segment (1.0±0.3) hour on a mean, whereas without bone cement allergy, pulmonary embolism, surgical site infection and other major complications. Of them, 78 cases got unilateral puncture, while 121 cases got bilateral puncture. There were 5 cases of bone cement leakage, including 3 cases of inter- vertebral space leakage and 2 cases of paravertebral blood vessel leakage, with no obvious clinical symptoms occurred and no special treat- ment was needed. The patients were followed up for 12~30 months, and the VAS score decreased from (7.9±1.4) before surgery, to (2.6±0.7) a day after surgery, and (2.4±0.6) at the last follow-up. The imaging examinations showed that the height of the anterior vertebrae of the af- fected vertebrae recovered obviously, whereas the cement was fully dispersed and filled in the fracture area with stable pedicle anchor. [Conclusion] This modified vertebroplasty does effectively reduce the risk of bone cement leakage, displacement and biological toxicity, thereby improving surgical safety, with satisfactory preliminary clinical outcomes.

Abstract:[Objective] To compare the clinical efficiency of Gong's four-step reduction and plaster-splint external fixation versus con- ventional manual reduction and plaster- splint external fixation in the treatment of ankle fractures. [Methods] A retrospective study was conducted on 90 patients who received manual reduction and external fixation with plaster splint for ankle fractures in our hospital from June 2020 to June 2022. According to preoperative doctor- patient communication, 45 patients received Gong's four- step reduction and plaster external fixation (the Gong's group), wile the other 45 cases received conventional manual reduction plaster external fixation (the conventional group). The clinical and imaging data were compared between the two groups. [Results] The VAS scores significantly de- creased (P＜0.05), while the AOFAS score and ankle ROM significantly increased in both groups over time after treatment (P＜0.05). The Gong's group proved significantly superior to the conventional group in terms of VAS score [(1.9±0.3) vs (2.4 ±0.3), P＜0.001], AOFAS score [(90.3±3.9) vs (86.4±4.4), P＜0.001] and ankle ROM [(51.4±4.9)° vs (49.0±5.2)°, P=0.027) 6 months after treatment. Regarding imaging, there was no significant difference in articular surface reduction quality between the two groups (P＞0.05), but the Gong's group was signifi- cantly better than the conventional group in terms of tibiocrural angle (TCA) [(76.5±4.8)° vs (73.8±4.5)°, P=0.007], medial clear space (MCS) [(3.5±0.3)mm vs (3.9±0.4)mm, P＜0.001] and tibiofibular clear space (TFCS) [(6.0±1.5)mm vs (6.6±1.2)mm, P=0.039] after treatment. [Conclusion] Both techniques of manual reduction do effectively treat ankle fractures. By comparison, the Gong's four-step reduction and plaster external fixation is superior to conventional manual reduction plaster external fixation.

Abstract:[Objective] To explore the effect of intermittent cold therapy on occult blood loss after open reduction and internal fixation (ORIF) of thoracolumbar fractures. [Methods] A total of 66 consecutive patients who were undergoing ORIF for acute thoracolumbar frac- tures in our department from January 2021 to November 2022 were included in this study. The patients were divided into two groups by ran- dom number table method, among them 33 patients in cold therapy (CT) group were treated with local intermittent cold compress 6 to 48 hours after surgery, while the other 33 patients in the routine group (RT) not received local cold compress anymore. The perioperative clini- cal and laboratory data were compared between the two groups. [Results] All the patients in both groups had OTIF performed smoothly with- out serious complications such as neurovascular injury or intraoperative massive bleeding. Although there were no significant differences in operation time, intraoperative blood loss and postoperative drainage volume between the two groups (P＜0.05), the CT group proved signifi- cantly superior to the RT group in terms of total blood loss [(608.5±386.2)ml vs (879.2±368.0)ml, P=0.008] and occult blood loss [(334.0± 355.4)ml vs (544.3±283.1)ml, P=0.010]. The VAS score for incision pain decreased significantly in both groups over time postoperatively (P＜0.05), which was not statistically significant between the two groups at any time points accordingly (P＞0.05). Regarding laboratory tests, there was no statistical significance in Hb and HCT between the two groups before surgery (P＜0.05), however, the CT group was significant- ly superior to the RT group in terms of Hb [(112.9±13.2)g/L vs (103.7±15.1)g/L, P=0.015; (117.7±12.7)g/L vs (106.3±12.3)g/L, P=0.001] and Hct [(34.8±3.9)% vs (32.7±4.0)%, P=0.039; (36.0±3.9)% vs (33.3±3.4)%, P=0.005] 3 days and 7 days postoperatively. [Conclusion] Local intermittent cold therapy does significantly reduce total blood loss, occult blood loss, and declines of Hb and Hct following ORIF of thoracolumbar fractures, which might be beneficial to the early postoperative recovery.

Abstract:[Objective] To investigate the clinical outcome of Brostr?m-Gould procedure with suture band augmentation for symptomat- ic os subfibulare accompanied with chronic lateral ankle instability. [Methods] A retrospective analysis was performed on 13 patients who were admitted to our department for symptomatic os subfibulare accompanied with chronic lateral ankle instability from May 2019 to No- vember 2020. All the patients had the anterior talofibular ligament repaired by Brostr?m-Gould procedure with anchor-suture band aug- mentation through a small incision. The perioperative and follow-up consequences were evaluated. [Results] All the patients got the opera- tion completed successfully, without serious complications such as injuries to nerve, blood vessel and tendon, the incision healed in one stage, and were followed up for (16.4±5.4) months on a mean. The anterior drawer test and varus test significantly improved at 6 months af- ter operation and at the last follow-up compared with those preoperatively (P＜0.05); however, there were no significant changes in ankle dorsal flexion-plantar flexion range of motion (ROM) and subtalar varus-valgus ROM (P＞0.05). The VAS score significantly decreased (P＜ 0.05), while the AOFAS ankle- hindfoot score significantly increased over time (P＜0.05). [Conclusion] The Brostr?m-Gould procedure with anchor-suture band augmentation does effectively treat symptomatic os subfibulare accompanied with chronic lateral ankle instability.

Abstract:[Objective] To explore the effect of motor control training (MCT) on femoroacetabular impingement (FAI) . [Methods] From May 2017 to July 2022, 45 patients with FAI were divided into two groups according to random number table method. Among them, 23 pa- tients were added motor control training on the basis of routine rehabilitation (the training group), while the other 22 patients received routine rehabilitation therapy only (the routine group). The data regarding therapy period and follow-up were compared between the two groups. [Results] There were no significant differences in treatment cycle, treatment frequency and VAS score for treatment compliance between the two groups (P＞0.05). Over time in follow- up period lasted for (8.2±3.1) months, VAS scores for pain, hip flexion strength and hip extension strength significantly improved in both groups (P＜0.05), the Harris score and SEBT score also improved in both groups, which proved statisti- cally significant in the training group (P＜0.05), while not statistically significant in the routine group (P＞0.05). At the latest follow-up, the training group proved significantly superior to the routine group in terms of pain VAS score [(2.2±1.0) vs (3.5±1.0), P＜0.05], Harris score [(79.4±6.9) vs (65.2±6.2), P＜0.05], hip flexor strength [(44.8±9.1)Nm vs (35.9 ±8.2)Nm, P＜0.05], and hip extensor strength [(68.4±6.7)Nm vs (56.3±7.0)Nm, P＜0.05] and SEBT score [(92.2±14.2) vs (81.6±17.0), P＜0.05]. [Conclusion] The MCT does effectively relieve pain, in- crease hip muscle strength and coordination ability, and improve the overall stability of the hip for FAI.
