We reviewed 57 adult patients at an average of 37 months after early internal fixation for displaced fractures of the distal humerus. Two-thirds had intercondylar (Muller type C) fractures, and one-third had articular comminution (type C3). A chevron olecranon osteotomy was used, with early active movement after fixation. Results were good or excellent in 76% with an average range of movement of 115 degrees. Early stable fixation by an experienced surgeon is recommended for these fractures.
This study was designed to compare the rigidity of the more commonly used techniques of internal fIxation of fractures of the olecranon. Cadaveric elbow joints were mounted in a jig and confrolled osteotomies performed to simulate transverse, oblique or comminuted fractures. Five techniques of internal fixation were tested by measuring movement at the fracture site after
We have studied aseptic loosening of the femoral component in 76 patients with primary total hip replacement using the Capital prosthesis. The mean follow-up was 26 months (10 to 37). Twelve femoral components (16%) were definitely and eight (10%) were possibly loose. They were characterised by a thin cement mantle (p < 0.001) and excessive residual cancellous bone in the proximomedial region (p < 0.01). We recommend that the cement mantle around the prosthesis should be 2 to 3 mm and that further long-term studies are needed to evaluate the wear properties of titanium-nitride-coated titanium femoral heads.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
