Article Synopsis
- Hand rotation and force application involve a coordinated effort between forearm bones, the interosseous ligament, and muscles.
- The review provides a detailed analysis of the anatomy related to the forearm's functionality.
- It highlights the mechanics of how these components work together to enable movement and manage external loads.
The impact of anatomic alignment on radiocapitellar pressure following radial head arthroplasty.
J Shoulder Elbow Surg
September 2024
Background: The incidence of radial head fractures is increasing, and radial head arthroplasty (RHA) is being more frequently used as treatment for irreparable fractures. Our objective was to compare radiocapitellar pressure between the native joint and 2 radial head prosthesis conditions: (1) a prosthetic head that was aligned to the forearm axis of rotation and (2) the same prosthesis with an axisymmetric nonaligned head.
Methods: Ten cadaveric specimens received a pressfit radial head prosthesis (Align; Skeletal Dynamics) for both prosthetic testing conditions.
Introduction: Concerning rates of nonunion in articular distal humerus fractures indicate an unsolved problem. The fixation principles of O'Driscoll describe linking the fractured articular segment to the distal humerus columns with compression screws which creates a stable fixed angle construct. A novel device has been introduced which utilizes an interlocking beam through the articular segment to connect the distal aspect of the medial and lateral plates, creating a linked construct.
