Abstract:
Objective: To explore the safety and preliminary effectiveness of transintervertebral release, bone impaction grafting, and posterior column compressed-closing in the treatment of osteoporotic vertebral fracture combined with moderate to severe spinal kyphosis. Methods: The clinical data of 21 elderly patients with osteoporotic vertebral fracture combined with moderate to severe spinal kyphosis were retrospectively analyzed between March 2016 and November 2017. There were 1 male and 20 females, aged 55-75 years, with an average of 64.8 years. The disease duration was 8-24 months, with an average of 13.1 months. The bone density T value ranged from -3.4 to -2.1, with an average of -2.3. Lesion segments: T 11 in 2 cases, T 12 in 6 cases, L 1 in 8 cases, L 2 in 1 case, T 11, 12 in 1 case, T 12, L 1 in 2 cases, and T 12, L 2 in 1 case. Preoperative neurological function was classified according to the American Spinal Injury Association (ASIA): 5 cases of grade D and 16 cases of grade E. All patients underwent transintervertebral release, bone impaction grafting, and posterior column compressed-closing. The effectiveness was evaluated by visual analogue scale (VAS) score and Oswestry dysfunction index (ODI) score before operation, at 3 months after operation, and at last follow-up. The neurological function was assessed by ASIA at last follow-up. Local kyphosis Cobb angle (LKCA), thoracic kyphosis (TK), lumbar lordosis (LL), and sagittal vertebral axis (SVA) were measured on the X-ray films of the full-length lateral spine of the patient before operation, at 1 week after operation, and at last follow-up. Results: No complication such as fracture of internal fixator or nerve injury occurred. LKCA, TK, and SVA were significantly improved at 1 week after operation and at last follow-up ( P<0.05). There was no significant difference between at 1 week after operation and at last follow-up ( P>0.05). There was no significant difference in LL before and after operation ( F=3.013, P=0.057). The VAS and ODI scores were significantly improved at 3 months after operation and at last follow-up, and further improved at last follow-up when compared with the scores at 3 months after operation, showing significant differences between time points ( P<0.05). Five patients with ASIA grade D neurological function recovered to grade E at 6 months after operation. Conclusion: Transintervertebral release, bone impaction grafting, and posterior column compressed-closing for treating osteoporotic vertebral fracture combined with moderate to severe spinal kyphosis has definite effectiveness, strong orthopaedic ability, and minimal trauma, which can effectively restore the sagittal balance of the spine, alleviate pain, and improve the patients' quality of life.
