The relationship between the abnormalities of the posterior elements and anterior elements in lumbosacral transitional vertebrae, and then the relationship between disc degeneration and lumbosacral transitional vertebrae were investigated. The modified Jinnaka's classification for the abnormalities of posterior elements and the modified igh's classification for the abnormalities of anterior elements were employed for this purpose. Of 597 patients with low back pain, 82 patients (14%) presented the posterior abnormalities and 90 patients (15%) presented the anterior abnormalities. Ninety% of type I of posterior abnormalities showed normal disc in anterior, whereas only 4% of type II-IV showed normal disc. Ninety-four% of type III of posterior abnormalities had type I and type II (and III) of anterior abnormalities which were thought typical fixed transitional vertebrae. It presents a greater than normal incidence of the disc degeneration, especially posterior slip at the level of just above the lumbo-sacral transitional vertebrae.

To study the several changes of the disc just above the lumbo-sacral transitional vertebrae, the features of slipping at this level were examined in 216 patients who had lumbo-sacral transitional vertebrae in both anterior and posterior sides.Type II and type III of modified Custivelli's classification for the posterior element and the modified Wigh's Classification for anterior element were employed for this purpose. The results were compared with 597 patients with low back pain who visited our clinic.Isthmus spondylolisthesis (8 cases, 3.7%) was almost same as the frequency in our low back pain patients. The slight increase was shown in degenerative spondylolisthesis (30 cases, 14%). The greater incidence was proved in posterior slip (115 cases, 52.3%) in this series compared to the our low back pain group (19%). The almost same incidence was shown in young group and in old group. The slight increase was found in type I and type II in the anterior classication and in type IIb and type IIIb in the posterior classification. In conclusion, posterior slip at the spine just above the lumbo-sacral transitional vertebrae was one of the special features.

Injuries to the thoracic and lumbar spine may result in severe instability with progressive neurologic defecit. Attention must be directed not only to restoring or improving neurologic function where possible, but also to promoting bony stability.We have carried out one stage decompression-stabilization procedure consisted of Harrington and anterior spinal fusion with anterior decompression in a total of 6 patients. All 6 of these with thoraco-lumbar spinal injuries had a neurogic defecit.The results have shown to be beneficial in restoring spinal alignment, allowing early mobilization of the patients, shortening rehabilitation, preventing the late complications of increasing deformity in all patients and recovering neurologic function in 4 cases with incomplete neurologic defecit.
