Abstract:
An 89-year-old man presented with right elbow pain after a low-energy fall. At age 2 years, he sustained an untreated distal humeral fracture dislocation, which resulted in progressive remodeling and formation of a functional pseudoarticulation. Despite permanent deformity, he maintained stable functional motion for decades and performed heavy manual labor. Imaging revealed a displaced distal humeral fracture through the chronically remodeled elbow. Open reduction and internal fixation with a variable-angle locking plate was performed, while the pseudoarticulation was intentionally left untreated. The patient regained his preinjury functional baseline.
Conclusion:
Fracture treatment should consider the clinical relevance of pre-existing but functional musculoskeletal abnormalities.

Fractures: 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...
