The Functional Outcome of Proximal Femoral Nail Antirotation-2 (PFNA-2) in Peritrochanteric Fractures of the Femur

Introduction Peritrochanteric fractures are defined as extra-articular fractures involving the trochanter and frequent extension into the subtrochanteric region. These fractures exhibit a bimodal distribution in terms of age. These fractures commonly happen in young individuals who experience high-energy trauma, often in combination with other injuries. In contrast, elderly individuals with osteopenia are more prone to fractures caused by low-energy trauma. Methods This study is a prospective investigation that was carried out over 30 months. The study focused on peritrochanteric fractures that were treated using proximal femoral nail antirotation-2 (PFNA-2) as a fixation device. A range of criteria were examined and documented, encompassing the mean duration of surgical procedures, blood loss, the duration of hospitalization, mobility, and any potential post-operative problems. Subsequent assessments were conducted at fixed intervals of two weeks, six weeks, three months, six months, and two years. The functional outcome analysis for all patients involved the utilization of the modified Harris hip score (HHS). Results The study involved 60 cases of peritrochanteric fractures. The average age was 56 years. The most common mode of trauma was trivial fall/slip (46.66%), followed by road traffic accidents (RTA) (31.66%) and falls from height (21.66%). The average operating time was 53.03±5.66 minutes. The average modified Harris hip score was 84.78 with 26.66% excellent, 70% good, and 3.33% fair results. Complications included superficial wound infection (5%), knee stiffness (11.66%), hip pain (8.33%), and shortening (1.66%). Conclusion PFNA-2 is a safe and easy implant option for treating peritrochanteric fractures as it preserves periosteal covering, minimizes blood loss, has a short operative time, and helps in early mobilization. PFNA-2 provides excellent outcomes in patients with peritrochanteric fractures with minimum complication rates compared to all other open methods and is highly recommendable.
