Study Notes
Bone Fractures: Complications, Pathophysiology, Effects of Smoking, Diagnosis, and Classification
- Complications of fractures include non-union and malunion
- Malrotation of a bone is common after femoral and tibial fractures
- Fracture complications are classified into immediate, early, and late occurrences
- Fracture healing process involves formation of fracture hematoma, blood clot, and collagen matrix
- Bone healing process includes mineralization of collagen matrix and remodelling into mature bone
- Factors affecting bone healing process include tobacco smoking, nutrition, and weight-bearing stress
- Smoking delays bone healing and increases the risk of fractures
- Diagnosis of bone fractures involves history, physical examination, and radiographic imaging
- Fractures can be classified as stable or unstable, and based on mechanism, soft-tissue involvement, displacement, fracture pattern, and fragments
- Mechanisms of fractures include traumatic, pathologic, and periprosthetic fractures
- Soft-tissue involvement in fractures can be closed/simple or open/compound
- Fracture patterns include linear, transverse, oblique, spiral, compression, impacted, and avulsion fractures
