| 【Abstract】 Objectives: To compare the spine and pelvic sagittal morphology between adult degenerative and isthmic lumbar spondylolisthesis. Methods: A total of 58 lumbar spondylolisthesis patients was included in this study, which ranged from March 2009 to March 2012. Long-cassette standing posterior-anterior and lateral radiographs of the spine and the pelvis were obtained from these patients in the fist-on-clavicle position. Isthmic group contained 29 patients(9 males, 20 females), aged from 23 to 67 years, which included 22 degree Ⅰ of slippage and 7 degree Ⅱ of slippage, diseased levels included 16 cases on L4 and 13 cases on L3. Degenerative group contained 29 patients(5 males, 24 females), aged from 45 to 85 years, which included 22 degree Ⅰ of slippage, 7 degree Ⅱ of slippage, diseased levels included 3 cases on L3, 23 cases on L4 and 3 cases on L5. There was no significant difference in Oswestry disability index(ODI) score between adult degenerative and isthmic lumbar spondylolisthesis patients(22.0 vs 25.5, P＞0.05). Pelvic parameters and spine sagittal parameters were as follows: pelvic incidence(PI), pelvic tilt(PT), sacral slope(SS), lumber lordosis(LL), thoracic kyphosis(TK), sagittal vertical axis(SVA). Meanwhile, slippage angle, slippage percentage and slippage distance of all patients were measured in radiographys. Based upon independent sample t test, all spino-pelvic parameters between two groups were evaluated and compared. Results: The LL, TK and Slippage angle in isthmic group was 52.2°±10.9°, 25.3°±11.1°, 9.9°±6.4° respectively, which was higher than those in degenerative group respectively(44.2°±15.4°、23.4°±12.6°，6.0°±3.9°，P＜0.05). However, the SVA in degenerative group was higher than that in isthmic group(30.6±40.6mm vs 4.6±24.9mm, P＜0.01). In addition, the pelvic parameters including PI(53.9°±11.5° vs 55.8°±10.8°), PT(17.0°±8.3° vs 22.9°±7.2°), SS(36.9°±8.7° vs 33.4°±9.9°), slippage percentage[（21.8±9.8)% vs (19.7±7.8）%] and slippage distance(6.2±2.7mm vs 5.6±1.9mm) showed no significant difference between two groups(P＞0.05). Conclusions: Compared with degenerative lumbar spondylolisthesis, isthmic spondylolisthesis is of higher TK, LL and Slippage angle. However, pelvic morphology between the isthmic and degenerative lumbar spondylolisthesis is similar. |
