Introduction:
Significant traumatic bone loss in developed countries occurs in a high proportion of open fractures ranging from 11.4% to 40%. However, literature from developing countries such as Uganda scarcely documents the prevalence and patterns of traumatic bone loss. Direct trauma and iatrogenic factors have been associated with traumatic bone loss as possible etiologies.
Objective:
The study was aimed at establishing the prevalence and patterns of traumatic bone loss following open long bone fractures, and identifying factors associated with traumatic bone loss among patients presenting to Mulago Hospital within 24 hours of sustaining the injury up to completion of the initial fracture debridement, reduction, and fixation.
Methodology:
It was a prospective cohort study conducted at Mulago Hospital. A total of 136 open long bone fractures were registered and physically examined for traumatic bone loss. Patients who consented were recruited consecutively to participate in the study. Data on the patients' sociodemographics and fracture patterns were collected using pretested questionnaires and analyzed using Stata version 12.
Results:
From 123 patients, a total of 136 open long bone fractures were registered. The prevalence of traumatic bone loss following open long bone fractures was 26.5%. Of the 36 open long bone fractures with traumatic bone loss, the more common pattern (61.1%) was significant traumatic bone loss (≥ 2.5 cm long). Commercial motorcycle riders (22.0%) and traders (20.3%) were the most common occupations associated with open long bone fractures. Gunshot injuries were the leading cause of traumatic bone loss in open long bone fractures.
Conclusion:
Our setting has a high prevalence of traumatic bone loss among open long bone fractures with the majority occurring in Gustilo type IIIB injuries of the tibia. The likelihood of traumatic bone loss is higher in open fractures caused by gunshots.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
