BACKGROUND Reverse total shoulder arthroplasty (RTSA) is widely used; however, the effects of RTSA geometric parameters on joint and muscle loading, which strongly influence implant survivorship and long-term function, are not well understood. By investigating these parameters, it should be possible to objectively optimize RTSA design and implantation technique. QUESTIONS/PURPOSES The purpose...

We report the case of a 74-year-old woman who sustained an intertrochanteric fracture of the femoral neck in a previously arthrodesed hip. The hip arthrodesis had been performed 53 years earlier to treat septic arthritis. The fracture was treated successfully using a double-plating technique with 4.5 mm titanium reconstruction plates.

results overall, ≥ 2 mm shortening of the radius was seen in 28% of the patients, 53% had 2 - 5 mm radial shortening and 19% of the patients had more than 5 mm shortening of the radius. most of the participants had acceptable outcomes. the mean angulation was 6.28 ± 2.85 degrees and the mean shortening was 3.92 ± 2.22. thirty-nine percent of the patients had an angulation of less than 5 mm, 56%...
