Risk factors, classification, and operative choices of femur fractures at a Tertiary Hospital: first report from Somalia

A traumatic femur fracture is a significant cause of morbidity, affecting one to three million individuals annually. The present is the first study investigated the epidemiological characteristics, risk factors, classification, mechanisms of injury, and early management of femoral fractures in Somalia. This retrospective epidemiological study included all patients with a femur fracture who were admitted for four years between November 2018 and December 2022 to the orthopedic and trauma surgery department. We reviewed patient demographic characteristics, including age and gender, the mechanism of injury, injury characteristics, and the type of fixation performed. We reviewed the radiographs and classified the fracture using the AO/OTA classification system. During the study period, a total of 402 patients were treated for femur fractures; 256 (64%) were males, and 144 (36%) were females. The mean patient age was 47.7 ± 8.5 years. Regarding the anatomical location of femur fractures, the proximal (31A, 31B) was the most common, accounting for 50% of the patients. Femur neck fracture (31B) was the most common in the proximal femur fractures. Gunshot 82 (59.42%) was the leading cause of femur shaft fractures. Most patients with femur shaft fractures were males; 150 (86.20%) and 152 (64.47%) were young patients between 19 and 40 years old. Almost half of the patients (86) with femur shaft fractures had open fractures. The distribution of the mechanism of injury significantly differed according to age (p < 0.001). Younger patients (< 40 years) were predominantly injured due to gunshot injuries compared to elderly cases (> 60 years), where falls from standing height were the primary mechanism of injuries. There was a statistically significant difference between the mechanism of injury and gender categories (p < 0.001). Male patients were injured mainly by gunshots in about 40%, while 80% of fractures in female patients were due to falls from standing height. Female fractures occurred primarily in the proximal, while the males had an equal fracture rate for proximal and shaft fractures. Femur fracture causes significant morbidity and mortality. The study findings revealed that the most common femur fracture type was femur neck fracture, and low-energy injuries were the most common mode of injury in the elderly. Proximal femur fractures occur in older age and mainly in females. Gunshots were the most common cause of femur shaft fractures in Somalia, a country that has struggled with wars for over 30 years.
