Abstract:
STUDY DESIGN: A retrospective radiologic study of 23 cases OBJECTIVES: This study evaluated the etiology of correction loss after surgical treatment of osteoporotic vertebral fractures with neurologic deficits SUMMARY OF LITERATURE REVIEW: osteoporotic vertebral fractures with neurologic deficits were treated with anterior decompression with posterior instrumentation or an Egg shell operation. MATERIALS AND METHODS: We experienced 23 cases treated surgically for osteoporotic vertebral fracture with neurologic deficits. In group A (16 cases), anterior decompression with posterior instrumentation were performed, with group B (7 cases) receiving an Egg shell operation. The kyphotic angle using Cobb's method and endplate injury were evaluated preoperatively, postoperatively, and at last follow up. Group A was subdivided into A1 and A2 according to preoperative and postoperative kyphotic angle, as well as being divided by endplate injury into subgroup a and b. Overcorrection of preoperative kyphotic angles were performed in A1, and undercorrection in A2 group, with endplate injury in subgroup a. RESULTS: Postoperative correction was 13.4 degrees+/-3.4degrees and correction loss was 9.68degrees+/-8.05degrees in group A, and 21.5degrees+/-5.0degrees and 8.0degrees+/-1.73degrees in group B, respectively. Correction loss of group A1 (13.4degrees +/-8.8degrees ) was significantly larger than A2 (4.71degrees +/-3.14degrees ) (p=0.011). The correction loss of group A1a (18.0degrees +/-9.3degrees ) was significantly larger than group A2 (8.5degrees +/-3.1degrees ) (p=0.050) and A2a (p=0.036). The correction loss of group A1b was significantly larger than group A2b (p=0.029), and correction losses were not significantly different in A2a (6.0degrees +/-4.0degrees ) and A2b (3.25degrees +/-1.7degrees ) (p=0.289). CONCLUSIONS: Less Correction loss was found in the undercorrection and non-endplate injury group
