Functional Outcome Following Intramedullary Nailing of the Femur: A Prospective Randomized Comparison of Piriformis Fossa and Greater Trochanteric Entry Portals

This report has been verified by one or more authors of the original publication.

110 patients with femoral shaft fractures were randomized to receive intramedullary nailing of the femur with the use of a trochanteric portal or a piriformis fossa entry portal. The results of the 12-month study indicated that the two studied interventions did not differ in terms of hip function, muscle strength, and analog pain scale values. It was also found that at 6-month follow-up the trochanteric portal group displayed better chair stand test scores; however, the difference between the two groups was not significant at 12-month follow-up.
