Is closed-suction drainage necessary for single-level lumbar decompression?: review of 560 cases.
Closed-suction drainage is commonly used for prevention of postoperative hematoma and associated neurologic compromise after lumbar decompression, but it remains unclear whether suction drainage reduces postoperative complications. ⋯ Level III, prognostic study. See Guidelines for Authors for a complete description of levels of evidence.

Pain relief, motion, and function after rotator cuff repair or reconstruction may not persist after 16 years.
Short- to medium-term rotator cuff repair reportedly relieves pain in 82% to 97% of patients and provides normal or almost normal shoulder function in 82% to 92%. However, it is unknown whether pain relief and function persist long term. ⋯ Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Rodent lumbar and caudal (tail) spine segments provide useful in vivo and in vitro models for human disc research. In vivo caudal models allow characterization of the effect of static and dynamic loads on disc mechanics of individual animals with time, but the lumbar models have required sacrifice of the animals for in vitro mechanical testing. ⋯ Improved methods to assess comparative models for disease or aging may permit enhanced clinical treatments and improved patient care.

Review Case ReportsCase report: calcific tendinitis of the rectus femoris: a rare cause of snapping hip.
Internal snapping hip is a syndrome caused by recurrent subluxation of the iliopsoas tendon. There is little agreement regarding the impinging sites responsible for the jerky motion of the tendon. Thus far, the lesser trochanter, anterior capsule, and iliopectineal eminence are considered the most likely catching sites. ⋯ Our case shows the rectus anterior direct head may be involved in the etiology of coxa saltans. Theoretically any thickening of the tendon might activate the same pathomechanism. Physicians should consider this possible new cause of internal snapping hip when the most common ones have been excluded, especially as it may be managed easily with steroid injection.

Curettage and cryosurgery for low-grade cartilage tumors is associated with low recurrence and high function.
Chondrosarcomas of bone traditionally have been treated by wide or radical excision, procedures that may result in considerable lifelong disability. Grade 1 chondrosarcomas have little or no metastatic potential and are often difficult to distinguish from painful benign enchondromas. Curettage with adjuvant cryosurgery has been proposed as an alternative therapy for Grade 1 chondrosarcomas given the generally better function after the procedure. However, because it is an intralesional procedure, curettage and cryosurgery may be associated with higher rates of recurrence. ⋯ Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.
