Management Of Subtrochanteric Femoral Fractures Using Proximal Femoral Nail

Abstract

Background: Fractures of the proximal femur are a big challenge in traumatology. Rapid strides in implant and instrumentations in quest of ideal fixation of subtrochanteric femoral fractures have made various options available.

Objective: The present study aims to study the role of standard proximal femoral nail (PFN) in the management of these fractures. This study aimed to evaluate the results of treatment of subtrochanteric femoral fractures using PFN.

Patients and methods: This prospective study conducted at Orthopedic Department, Zagazig University Hospital, from November 2020 to July 2021. It included 24 patients, complaining of closed subtrochanteric fractures treated with PFN (Gamma intramedullary nail). The age ranged from 23 to 87 years (with mean 54.21 years), 13 of them were males and 11 females. Road traffic accident (RTA) represented the most common mechanism of injury in 10 patients (41.7%) while fall down represented (37.5%) in 9 patients, and fall from height in 5 patients (20.8%).

Results: there was statistically significant difference in HHS among patients with different age groups, mechanism of injury and presence of diabetes mellitus (DM) as associated condition. Statistically there was significant correlation between type of reduction and diabetes mellitus with Harris hip score.

Conclusion: This study concluded that the Gamma nail is an excellent choice in treatment of subtrochanteric fractures as it has many advantages as allowing for early functional exercise and full weight-bearing of the affected limb, shortening the duration of operation, high rotation stability, small wounds and minimizing blood loss along with risk of infection
