Abstract:
Distal humeral fractures in adults are relatively uncommon injuries that require operative intervention in the majority of cases. Dual plate fixation, with placement of a separate strong plate on each column and orientation of the plates either at 90° or 180° to each other, is indicated for all adult fractures involving both columns of the distal part of the humerus. Acute total elbow arthroplasty is the preferred treatment for elderly patients with a displaced, comminuted, intra-articular distal humeral fracture that is not amenable to stable internal fixation. Displaced coronal shear fractures of the distal humeral articular surface require operative fixation, most typically via a lateral approach.

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...

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...
