Functional Outcome and Complications Using the Intramedullary Hip Screw for Intertrochanteric Fractures

We prospectively studied 110 consecutive patients with intertrochanteric hip fractures treated with the 130° angle, 10-mm short IMHS intramedullary hip screw (IMHS, Smith & Nephew, Richards, Memphis, TN). Surgery was performed within 36 hours from admission; all patients were mobilized immediately postoperatively. Fracture union, pre- and post-operative mobility status and complications were evaluated. Eighty patients were included in the postoperative evaluation for a mean followup of 14 (range, 9 to 25) months. Mortality was 19%. Union occurred in 79 fractures within 6 months from surgery; there was one case of screw cut-out and one case of deep venous thrombosis. Periprosthetic femoral shaft fractures were not observed. At the latest examination, the mean mobility score decreased from 8.4 š 1.6 to 7.1 š 2.1 (p D 0.0001); 26 patients (32%) fully achieved the preoperative mobility score and 54 patients (68%) achieved more than 90% of the preoperative mobility score. The IMHS intramedullary hip screw represents a reliable method for the treatment of patients with intertrochanteric hip fractures, and provides for early mobilization and rehabilitation of the patients with acceptable complications.
