Twelve patients who had received modular proximal femoral replacement as primary treatment for proximal femoral fractures were evaluated along with nine patients treated with salvage proximal femoral replacement for failed internal fixation. After the surgical procedure, patients were evaluated at regular follow-up intervals and contacted by phone at the conclusion of this study. Patient functional results were evaluated using the Merle D'Aubigne hip rating scale, which measures pain, motion and ambulatory status. Routine radiographs were also obtained at each patient visit.
On average, patients who received modular proximal femoral replacement as the primary surgery for their femoral fractures enjoyed a high-level functional result and had few complications. Subjects who received salvage femoral replacement had a less optimal outcome and experienced more complications. Nonetheless, final post-operative MDA score was significantly increased from pre-operative levels.
Modular proximal femoral replacement is a viable option in the primary fracture or revision setting, and has been shown to have a reasonable outcome, especially when the nature of initial injury is taken into account.
