The purpose of this study was to evaluate the mechanical effects of using an injectable calcium phosphate cement, Norian Skeletal Replacement System (SRS), which is replaced by the native remodeling process, to augment sliding hip screw fixation of unstable intertrochanteric fractures in a cadaver model. ⋯ SRS augmentation of unstable, intertrochanteric fractures significantly improved overall stability, facilitated load transfer across the fracture, and decreased both shortening of the proximal femur and stress on the sliding hip screw.

This study was undertaken to collect information about the organization of orthopaedic trauma services in different types of hospitals, with particular emphasis on hospital support arrangements in different practice situations. ⋯ There are differences in organization of orthopaedic trauma care between hospitals, which may be related to hospital size, academic affiliation, and orthopaedic department organization. Further study is necessary to determine whether organizational differences translate into differences in patient outcome after trauma.

Comparative Study
Evaluation of the syndesmotic screw in low Weber C ankle fractures.
To determine the functional and radiographic outcome of low Weber C ankle fractures and to evaluate the contribution of the syndesmotic screw in their outcome. ⋯ Judicious fixation of Weber C type injuries within five centimeters of the ankle joint, with or without a syndesmotic screw, gives similar results. Obligatory fixation of these fractures with syndesmotic screws appears to have no benefit and creates the need for an additional procedure.

To determine the effectiveness of circular wire external fixation in the treatment of complex (Schatzker Type VI) fractures of the tibial plateau. ⋯ Results perhaps would have been improved by more frequent open reduction, bone grafting, and internal fixation of fractures with severely depressed articular fragments. However, the use of circular external fixation obtained results comparable with other series, and we believe it is appropriate for treatment of these complex tibial fractures, especially those with a poor soft-tissue envelope.

To evaluate the effect of previous cerebrovascular accident on outcome after hip fracture. ⋯ The functional recovery of elderly hip fracture patients who had a prior cerebrovascular accident was similar to that of patients who had no history of a prior cerebrovascular accident.
