The aim of this study is to investigate retroperitoneal organ distribution with the retroperitoneal approach in the lateral decubitus position. ⋯ We observed anterior migration in L-CT in all retroperitoneal organs. However, a considerable percentage of kidney and that of descending colon remain obstruent while performing LIF. We discuss that the preoperative imaging evaluation is beneficial, and gentle and meticulous surgical detachment is essential for safe and reliable lateral approach surgery, especially in the case that the descending colon extends outside zone P in S-CT.

The present study aimed to determine whether obtaining adequate lumbar (LL) or segmental (SL) lordosis during instrumented TLIF for one-level degenerative spondylolisthesis affects midterm clinical outcome. ⋯ II. These slides can be retrieved under Electronic Supplementary Material.

Unilateral sacroiliitis (US) is an uncommon disease with varied etiology. The differentiation between infective and inflammatory causes for US based on MRI alone is often difficult. We studied the efficacy of MRI findings in comparison with tissue studies in the diagnosis of US. ⋯ MRI had high sensitivity (71%) and 100% specificity in diagnosing inflammatory sacroiliitis while it had low specificity, but 100% sensitivity for diagnosing infective sacroiliitis. Hence, patients diagnosed as inflammatory sacroiliitis in MRI are unlikely to benefit from further tissue studies while percutaneous biopsy is recommended in patients diagnosed in MRI as infective sacroiliitis.

The presence of Propionibacterium acnes in a substantial component of resected disc specimens obtained from patients undergoing discectomy or microdiscectomy has led to the suggestion that this prominent human skin and oral commensal may exacerbate the pathology of degenerative disc disease. This hypothesis, therefore, raises the exciting possibility that antibiotics could play an important role in treating this debilitating condition. To date, however, little information about antibiotic penetration into the intervertebral disc is available. ⋯ Positively charged antibiotics appear more appropriate for future studies investigating potential options for the treatment of low-virulence disc infections.
