Abstract:[Objective] To investigate the short-term clinical consequence of core decompression combined with porous titanium cage implantation for early femoral head necrosis. [Methods] A retrospective study was conducted on 10 patients (12 hips) who had early-stage femoral head necrosis treated by core decompression combined with porous titanium cage implantation in our department from October 2022 to March 2023. The clinical and imaging documents were evaluated. [Results] All the patients had abovesaid surgical procedures performed successfully without important vascular and nerve injuries, and other complications, and were followed up for an average of (14.5± 2.1) months. Compared with those before surgery, the VAS score was significantly decreased [(7.0±1.2), (2.0±1.0), P＜0.001], whereas the Harris score [(72.0±4.2), (91.0±3.5), P＜0.001], hip flexion-extension range of motion (ROM) [(54.8±3.7)°, (89.7±3.3)°, P＜0.001], hip internal-external rotation ROM [(35.3±3.2)°, (60.7±2.9)°, P＜0.001] were significantly increased at the last follow-up. As for imaging, there were no significant changes in ARCO stage and JIC stage at the last follow-up compared with those before surgery (P＞0.05). At the last followup, 1 patient had aggravation in the necrotic area of the femoral head. [Conclusion] The core decompression and porous titanium cage implantation achieve satisfactory clinical outcome in the short term for the earl-stage femoral head necrosis.
