Predictors associated with neurological recovery after anterior decompression with fusion for degenerative cervical myelopathy

Abstract Background Anterior decompression with fusion (ADF) has often been performed for degenerative cervical myelopathy (DCM) in patients poor spine alignment and/or anterior cord compression. We aimed to identify clinical and radiological predictors associated neurological recovery after ADF. Methods This post-hoc analysis from a prospective multicenter study included who were scheduled ADF DCM. The received other surgeries (laminoplasty, posterior fusion) excluded. associations between baseline radiographic variables (age, sex, body mass index, etiology, lordosis, range of motion, C7 slope, C2-7 sagittal vertical axis [SVA], thoracic kyphosis [TK], lumbar sacral SVA, pelvic tilt, T1 angle [TPA], the Japanese Orthopedic Association score assessment [C-JOA], European Quality Life Five Dimensions Scale [EQ-5D], Neck Disability Index [NDI], Physical Component Summary SF-36 [PCS], Mental SF-36) rates as outcome investigated univariate regression analysis. Then, independent increased evaluated using stepwise multiple Results In total, 37 completed 1 year follow-up. rate was significantly correlated SVA (p = 0.001) TPA 0.03). Univariate analyses showed that age (Regression coefficient ? 0.92, p 0.049), 0.57, 0.004) PCS 0.80, 0.03) rate. identified TK ( 0.01), 0.03), According this prediction model, following equation obtained: 8.26 + 1.17 × (TK) 0.45 (SVA) 0.85 (PCS) 0.002, R 2 0.44). Conclusion Patients lower TK, score, higher more likely have Therefore, DCM these undergo should be warned about required provide adequate informed consent.
