Intramedullary Devices for the Treatment of Unstable Pertrochanteric Fractures - Epidemiological Data and Rates of Complications

This trial is a prospective randomized controlled study including the treatment of AO/OTA 31-A2 fractures in 200 patients with 2 different surgical devices. 100 patients are treated with a Gamma Nail 3 (GN3) (Stryker) the other 100 patients with a Proximal Femoral Nail Antirotation (PFNA) (Synthes).

All surgeries are performed by trauma surgeons at a Level 1 University Hospital. One hundred patients are randomized to the gamma nail and 100 are randomized to the proximal femoral nail for treatment fixation. A 1:1 randomization is performed using sealed envelopes (200 in total), which are opened by the surgeon immediately before the operation.

Patients missing an informed consent form, incomplete chart, or showing a pathologic fracture are getting excluded from final comparisons.

Patients anthropometric data as well as pre-injury mobility assessments, and ASA will be documented. Furthermore the time from admission to going to surgery, surgery length, length of stay and mobility assessment at dischargement are recorded.

After surgery the stay in the hospital is documented precisely and patients are scheduled for next appointments 2 weeks, 6 weeks, 3 months, 6 months and 1 year after surgery.
