Lumbar spinal osteotomy for kyphosis in ankylosing spondylitis: the significance of the whole body kyphosis angle.
Retrospective analysis of 11 consecutive patients with ankylosing spondylitis who underwent lumbar spinal osteotomy for severe kyphosis, with a mean follow up of 4 (2 to 8.5) years. The chin brow vertical angle, thigh flexion angle, and the whole body kyphosis angle (WBKA) were measured on the clinical photographs of the patient in standing. The lumbar lordosis, thoracic kyphosis, total kyphosis, sacral slope, and sagittal balance were measured on the standing radiographs. ⋯ The WBKA correlated closely with the amount of lordosis correction in lumbar spine. The intraobserver and interobserver reproducibility of the WBKA was verified by statistical analysis. In our opinion the measurement of the WBKA on the preoperative photograph is helpful in planning the lumbar osteotomy.

Management of deep wound infection after posterior lumbar interbody fusion with cages.
To evaluate long-term treatment outcome of patients with infected posterior lumbar interbody fusion (PLIF) managed with surgical debridement and or prolonged antiobiotic treatment without removal of the interbody cages. ⋯ In cases of postoperative deep wound infection after PLIF with cages, removal of the interbody implants is not necessary. Treatment is composed of prolonged antibiotic therapy guided by antimicrobial susceptibility of the isolated bacteria and supplemented with extensive surgical debridement if needed.
