Randomized Controlled Trial Comparative StudyA comparison of the long gamma nail with the sliding hip screw for the treatment of AO/OTA 31-A2 fractures of the proximal part of the femur: a prospective randomized trial.
Controversy exists with regard to whether to treat AO/OTA 31-A2 fractures of the proximal part of the femur with an intramedullary device or an extramedullary device. A prospective, randomized, controlled trial was performed to compare the outcome of treatment of these unstable fractures of the proximal part of the femur with either a sliding hip screw or a long gamma nail. ⋯ When compared with the long gamma nail, the sliding hip screw should remain the gold standard for the treatment of AO/OTA 31-A2 fractures of the proximal part of the femur because it is associated with similar outcomes with less expense.

Ninety-day mortality after intertrochanteric hip fracture: does provider volume matter?
Research on the relationship between orthopaedic volume and outcomes has focused almost exclusively on elective arthroplasty procedures. Geriatric patients who have sustained an intertrochanteric hip fracture are older and have a heavier comorbidity burden in comparison with patients undergoing elective arthroplasty; therefore, any advantage of provider volume in terms of mortality could be overwhelmed by the severity of the hip fracture condition itself. This study examined the association between surgeon and hospital volumes of procedures performed for the treatment of intertrochanteric hip fractures in Medicare beneficiaries and inpatient through ninety-day postoperative mortality. ⋯ Only the highest-volume hospitals showed an inpatient mortality benefit for Medicare patients with intertrochanteric hip fractures. Unlike the situation with elective arthroplasty procedures, our findings do not indicate a need to direct patients with routine hip fractures exclusively to high-volume centers, although the higher mortality rates found in the lowest-volume hospitals warrant further investigation.

Articular cartilage has a poor intrinsic capacity for healing. The goal of surgical techniques to repair articular cartilage injuries is to achieve the regeneration of organized hyaline cartilage. Microfracture and other bone marrow stimulation techniques involve penetration of the subchondral plate in order to recruit mesenchymal stem cells into the chondral defect. ⋯ The primary theoretical advantage of autologous chondrocyte implantation is the development of hyaline-like cartilage rather than fibrocartilage in the defect, which presumably leads to better long-term outcomes and longevity of the healing tissue. Use of synthetic scaffolds is a potentially attractive alternative to traditional cartilage procedures as they are readily available and, unlike allogeneic tissue transplants, are associated with no risk of disease transmission. Their efficacy, however, has not been proven clinically.

Multicenter StudyMaintenance of hardware after early postoperative infection following fracture internal fixation.
The development of a deep wound infection in the presence of hardware after open reduction and internal fixation presents a clinical dilemma, and there is scant literature to aid in decision-making. The purpose of the present study was to determine the prevalence of osseous union with maintenance of hardware after the development of postoperative infection within six weeks after internal fixation of a fracture. ⋯ Deep infection after internal fixation of a fracture can be treated successfully with operative débridement, antibiotic suppression, and retention of hardware until fracture union occurs. These results may be improved by patient selection based on certain risk factors and the specific bacteria and implants involved.
