A minimally invasive stabilizing system for dorsal pelvic ring injuries.
Open reduction and stabilization of dorsal pelvic ring injuries is accompanied by a high rate of soft tissue complications. Minimally invasive techniques have the potential to decrease soft tissue trauma, but the risk of iatrogenic nerve and vessel damage through the reduced surgical exposure should be considered. We treated these injuries using a transiliac internal fixator (TIFI) in a minimally invasive technique characterized by implantation of a pedicle screw and rod system, bridging the sacroiliac joints and the sacral area. ⋯ Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Influence of gender and fixation stability on bone defect healing in middle-aged rats: a pilot study.
Gender and stability of fixation independently influence bone regeneration but their combined effects are unclear. ⋯ While female gender appears to reflect a risk for impaired bone healing in middle-aged female rats, clinical studies would be required to confirm the finding in humans.

An articulating antibiotic spacer controls infection and improves pain and function in a degenerative septic hip.
Treating septic arthritis of the hip with coexisting advanced degenerative disease is challenging. The use of primary total hip arthroplasty (THA) has led to postoperative infection rates as high as 22%. Insertion of antibiotic spacers with subsequent reimplantation of a THA controls infection and improves pain and function in patients with periprosthetic infections. ⋯ Level IV, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

Comparative StudyWomen recover faster than men after standard knee arthroplasty.
Specific anatomic differences are believed to account for gender-specific function and health-related quality of life after TKA. However, there are conflicting data in the literature regarding these gender-specific outcomes, especially as woman appear to have surgery later in the course of the disease compared with men. ⋯ Level II, prognostic study. See the guidelines for authors for a complete description of levels of evidence.
