Retrospective review of the clinical and radiographic results in adult revision spine deformity surgery using the techniques of osteotomies to effect spine balance and curve correction. ⋯ This study demonstrates multiple vertebral osteotomies (anterior and/or posterior) in the management of rigid adult spine deformities and deformity correction with an acceptable complication rate. Use of vertebral osteotomies for patients undergoing revision spine surgery is a safe and reasonable approach to obtain an arthrodesis.

A study of the transforaminal lumbar interbody fusion and the posterior lumbar interbody fusion techniques was performed. ⋯ In this comparison of patients receiving transforaminal lumbar interbody fusion versus posterior lumbar interbody fusion, no complications occurred with the transforaminal approach, whereas multiple complications were associated with the posterior approach. Similar operative times, blood loss, and duration of hospital stay were obtained in single-level fusions, but significantly less blood loss occurred with the transforaminal lumbar interbody approach in two-level fusions. The transforaminal procedure preserves the interspinous ligaments of the lumbar spine and preserves the contralateral laminar surface as an additional surface for bone graft. It may be performed at all lumbar levels because it avoids significant retraction of the dura and conus medullaris.

A case of pyogenic spondylitis in S1-S2 is presented. ⋯ Findings from this study show that pyogenic spondylitis can occur in immobile S1-S2.

The case report of a 60-year-old man with late onset back pain after lumbar spine fusion is presented. ⋯ The pedicle is the weakest point in the neural arch after posterolateral fusion. Although movement continues at the level of the disc space anteriorly, the pedicle is susceptible to fracture. Pedicle fracture is a rare late complication of posterolateral lumbar spine fusion.
