Abstract:[Objective] To compare the clinical outcomes of two kinds of traditional Chinese medicine (TCM) therapy for adolescent lumbar disc herniation (ALDH). [Methods] A total of 104 ALDH patients who underwent non-surgical treatment in our hospital from February 2020 to March 2022 were included into this study, and divided into two groups by random number table method. Of them, 52 patients were treated by Pingji method, including optimal traction, TCM fumigation, manual release and holistic spinal manipulation, while the other 52 patients received conventional treatment, involving optimal traction, TCM fumigation and conventional manual treatment. Clinical and imaging data were compared between the two groups. [Results] The Pingji group got clinical cure significantly earlier than conventional group [(253.2±26.8) d vs (272.6±29.5) d, P<0.001]. The follow-up period was of (15.3±3.7) months on an average, and lower back pain and leg pain VAS scores, as well as the ODI score in both groups were significantly decreased at the last follow-up compared with those before treatment (P<0.05). At the last follow-up, the Pingji group was significantly superior to the conventional group in terms of lower back pain VAS [(1.5±0.3) vs (2.6±0.5), P<0.001], leg pain VAS score [(1.8±0.4) vs (2.9±0.6), P<0.001] and ODI score [(8.2±1.7) vs (13.6±2.5), P<0.001]. As for imaging evaluation, the spinal canal occupation rate, T1-pelvic angle (TPA), pelvic tilt (PT), sacral slope (SS), lumbar lordosis (LL), and thoracic kyphosis (TK) were significantly improved at the latest follow-up compared with those before treatment. At the last follow-up, the Pingji group also was significantly better than the conventional group in terms of canal occupying rate [(2.0±0.3)% vs (3.5±0.6)%, P<0.001], TPA [(15.3±2.4)° vs (18.6±3.5)°, P<0.001], PT [(14.2±1.8)° vs (16.7±2.5)°, P<0.001], SS [(29.4±6.1)° vs (25.8±4.9)°, P<0.001], LL [(37.6±6.7)° vs (30.5±5.3)°, P<0.001], TK [(25.9±5.8)° vs (20.3±4.6)°, P<0.001]. [Conclusion] The Pingji therapy is effective in the treatment of AL-DH patients, which can improve the function, reduce back pain and leg pain, and regain the spinopelvic sagittal balance.
