    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
