Abstract:
Fractures and ligamentous lesions of the thumb ray are frequent due to the exposed position of the thumb. A thorough anatomical understanding with respect to the joints and stabilizing ligaments is essential for a targeted examination, the selection of appropriate imaging diagnostics and the decision for a surgical or conservative treatment approach. Misdiagnoses or untreated injuries can lead to impaired functionality, pain and instability, which can substantially impair the function of the hand, particularly thumb opposition.

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...
