Review of the clinical and radiologic records of patients who underwent one-level posterior lumbar interbody fusion (PLIF) at L4-L5. ⋯ There is no evidence from the results that postoperative narrowing of the adjacent disc and preoperative narrowing of the L5-S1 disc affects the clinical outcome of L4-L5 PLIF.

Case Reports
Results of a longer than 10-year follow-Up of patients with rheumatoid arthritis treated by occipitocervical fusion.
Evaluation of results a longer than 10-year follow-up of patients with upper cervical lesions due to rheumatoid arthritis who underwent occipitocervical fusion. ⋯ Occipitocervical fusion for patients with rheumatoid arthritis is useful for decreasing nuchal pain, reducing myelopathy, and improving prognosis.
-
Independent evaluation of 18 patients with multilevel cervical spondylotic myelopathy who underwent threadwire T-saw laminoplasty. ⋯ T-saw laminoplasty appears to be a safe and effective method of arresting the progression of myelopathy and allowing marked functional improvement in most patients with multilevel cervical spondylotic myelopathy. [Key Words: cervical spine, decompression, laminoplasty, myelopathy, spondylosis]

Randomized Controlled Trial Clinical Trial
Instrumented and noninstrumented posterolateral fusion in adult spondylolisthesis--a prospective randomized study: part 2.
A prospective randomized study was performed. ⋯ Lumbar posterolateral fusion performed in situ for adult isthmic spondylolisthesis relieves pain and improves function. The use of supplementary transpedicular instrumentation does not add to the fusion rate or improve the clinical outcome.

Randomized Controlled Trial Comparative Study Clinical Trial
Surgery versus conservative management in adult isthmic spondylolisthesis--a prospective randomized study: part 1.
A prospective randomized study was performed. ⋯ Surgical management of adult isthmic spondylolisthesis improves function and relieves pain more efficiently than an exercise program.
