Review Case Reports
Intra-abdominal migration of a lag screw in gamma nailing: report of a case.
An 83-year-old female patient was referred to the emergency room with progressive pain on mobilization. Three weeks before presentation, she had been treated with a gamma nail for an unstable right intertrochanteric fracture. Pelvic x-ray showed an intra-abdominally migrated lag screw. ⋯ After 6 weeks of immobilization, the patient did well. No late complication occurred. A review of the literature with an emphasis on pathophysiology of intra-abdominal or retroperitoneal migration of lag screws in gamma nailing is presented.

Multicenter Study
Cephalomedullary screws as the standard proximal locking screws for nailing femoral shaft fractures.
In 2004, we modified our technique for the stabilization of femoral shaft fractures so that all fractures were stabilized using a reconstruction nail with proximal locking screws oriented into the femoral head. The rationale for this was twofold: first, potentially "missed" associated femoral neck fractures would be stabilized. Second, hip fractures that might occur later in life above the intramedullary nail might be avoided. The purpose of this study therefore was to determine whether there were any risks to patients treated for femoral shaft fractures with antegrade nails using cephalomedullary proximal locking screws. ⋯ Using a reconstruction nail and cephalomedullary proximal locking screws for antegrade femoral nailing of femoral shaft fractures was not associated with major complications in this series. This modification of standard femoral nailing offers potential advantages, including fixation of any "missed" associated femoral neck fractures and prevention of late hip fractures that might occur above the nail.

To investigate the clinical and radiographic results after operative treatment of complete symphyseal disruption resulting from childbirth and to evaluate residual pain and implant failure in relation to the timing of surgery. ⋯ Operative management significantly improved the functional outcomes of all three subgroups and can be an acceptable treatment option for labor-induced complete symphysis pubis disruption.

Interprosthetic femoral fractures, ones occurring between ipsilateral total hip and total knee arthroplasties, are an increasingly common and challenging problem for orthopaedic surgeons. The purpose of this study was to report specific fracture locations and treatment outcomes associated with a protocol of femoral plate fixation that spanned the interprosthetic zone applied with modern soft tissue preserving reduction techniques without adjuvant bone grafts. ⋯ Interprosthetic femoral fractures tend to occur more frequently in the supracondylar region about total knee arthroplasty components than in the diaphysis about hip stems. Modern biologic plating techniques that span the entire interprosthetic zone to eliminate additional stress risers show reliable union rates without the use of adjuvant bone graft while maintaining limb alignment and implant survivorship.

1) To introduce a computed tomography-based "three-column fixation" concept; and 2) to evaluate clinical outcomes (by using a column-specific fixation technique) for complex tibial plateau fractures (Schatzker classification Types V and VI). ⋯ Three-column fixation is a new fixation concept in treating complex tibial plateau fractures, which is especially useful for multiplanar fractures involving the posterior column. The combination of posterior and anterior-lateral approaches is a safe and effective way to have direct reduction and satisfactory fixation for such difficult tibial plateau fractures.
