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.

To evaluate the efficiency of a solid femoral nail and interlocking spiral-blade, inserted without reaming (UFN/ spiral blade, Synthes-Stratec, Oberdorf, Switzerland), for the fixation of pathologic and impending pathologic fractures of the proximal femur, particularly those involving the subtrochanteric area. ⋯ Femoral nail insertion without reaming using an interlocking spiral blade provides appropriate stabilization of the proximal femur in case of metastatic lesions, even with extensive subtrochanteric involvement. Although the nails were inserted without reaming, this did not avoid the risk of fat embolization syndrome. This study only addressed results in patients with short-term survival.

To determine the effectiveness of exchange reamed nails for treatment of aseptic femoral delayed unions and nonunions. ⋯ Reevaluation of routine exchange nailing as the recommended treatment for aseptic femoral delayed union or nonunion may be required. A significant number of patients who undergo reamed exchange nailing will require additional procedures to achieve fracture healing.

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 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.
