Osteoporosis-related appendicular fractures in Tikur Anbessa Specialized Hospital, Ethiopia: a prospective observational study.

Abstract

Examine the frequency of osteoporotic fractures among patients presenting to Tikur Anbessa Specialized Hospital. This is an observational study of prospectively collected data between January 2018 and December 2021. Patients were categorized as having osteoporotic fracture if they were 40years or older, sustained a low-energy injury, and had characteristic fracture patterns to the hip, proximal humerus, distal radius, tibia (in females only), clavicle, and scapula. A descriptive analysis was carried out to assess patient demographics. Risk factors were then evaluated using a binary logistic regression model. A total of 4712 orthopedic injury patients presented to the emergency department with 4422 fracture cases. Of these, 461 fulfilled the diagnostic criteria for osteoporotic fractures. The overall rate of osteoporotic fractures was 10.4% of all patients with fractures and 31.8% of those 40years or older. Overall, 63.3% were female. One in four females and 5% of males with musculoskeletal trauma had an osteoporotic fracture. Osteoporotic hip fractures made up 59.9% of osteoporotic fractures and 5.9% of all fractures, followed by distal radius (23%), tibia in females (8.2%), and proximal humerus (7.4%). Pelvis (2.6%), clavicle (0.9%), and scapula (0.2%) fractures were found to be rare. Among all patients with fractures following low-energy injuries, when patients were aged 50years and older, there was a higher risk that the trauma resulted in an osteoporotic fracture. This figure was highest among those aged 80years and older (odds ratio (OR), 11.88; 95% CI, 7.01-20.11). Further studies need to be done to show the prevalence of osteoporosis and osteoporotic fractures in Ethiopia and examine risk factors. Devising strategies for preventing, treating, and rehabilitating osteoporotic fractures is critical.
