Biomechanical evaluation of the risk of secondary fracture around short versus long cephalomedullary nails.

Introduction: For proximal femur fractures, long cephalomedullary nails (CMNs) are often selected to avoid a diaphyseal stress riser at the tip of a shorter nail. Secondary peri-implant fracture rates for long and short CMN have not been shown to differ clinically. This study biomechanically compares both CMN in a cadaveric model.

Open extremity fractures: impact of delay in operative debridement and irrigation.

Background: Early (<8 hours) operative debridement and irrigation (D&I) of open fractures are considered essential to reduce the risk of deep infection. With the advent of powerful antimicrobials, this axiom has been challenged. The current study evaluates the rates of deep infections of open fractures in relation to the time to the first D&I.

Peri-implant fracture of the femur in an 11-year-old: a case report.

Fracture of the femur in the area of a pre-existing implant is not common in an adolescent. We report the case of a fracture, in the area of a pre-existing implant in an 11-year-old boy, after a fall from a bike. We are not aware of any similar reports in the literature.

Mechanical effects of the extended trochanteric osteotomy.

Background: The extended trochanteric osteotomy was introduced as a safe and effective exposure technique for revision hip surgery; however, intraoperative iatrogenic femoral fractures have been reported. This study examined the effects of the extended trochanteric osteotomy on the torsional strength of the femur with use of cadaver bones. We hypothesized that repair of the osteotomy fragment would restore the torsional strength to that of an intact femur and that an osteotomized femur containing a well-fixed stem would have the same torsional strength as an intact femur with a stem.
