Osteoporosis was considered the main risk factor for hip fracture. However, hip fractures can also occur in young patients with no osteoporosis. Although several studies have reported on insufficiency-type fractures of the femur, there are limited reports on the impact of hip geometry on fatigue-type femoral fractures in young individuals, particularly in young military recruits.
Subchondral fatigue fracture of the femoral head (SFFFH) mainly occurs in young military recruits and might be confused with osteonecrosis of the femoral head. However, less research focuses on the risk factor for SFFFH.
Our study aimed to identify the intrinsic risk factors for SFFFH in young Chinese military recruits.
X-ray and magnetic resonance imaging data were used for analysis. And logistic regression, receiver operating characteristic curve analysis, and independent samples t-test were performed to identify the risk factors for SFFFH.
Overall, our findings indicate that a small anterior acetabular sector angle (AASA) indicates poor anterior coverage of the femoral head and can increase the risk of SFFFH in young patients. Since patients with a history of intense military training may be at higher risk for SFFFH, early detection and appropriate management are crucial to prevent further deterioration of the femoral head and preserve joint function.
Based on the findings of the study, we recommend orthopedic surgeons not to exclude the possibility of SFFFH in patients who present with hip pain and have a history of intense military training, particularly if they have a small AASA.
We advocate for the dissemination of scientific knowledge amongst high-risk populations in order to promote timely intervention in cases of SFFFH.
