Metacarpal Fractures: Anatomy, Injuries and Treatment - Overview

Pdf Summary

Fractures and dislocations of the fingers and hand can be complex injuries that require careful management. This summary provides an overview of the treatment options for various types of fractures and dislocations, based on the information provided in the document text.<br /><br />Fractures and dislocations of the proximal interphalangeal (PIP) joint can be treated with closed reduction and pinning using a dorsal block pinning technique. In cases of more severe injuries, hemi-hamate arthroplasty can be used to reconstruct the PIP joint.<br /><br />Fractures of the metacarpal bones can be treated with different methods depending on the location and severity of the fracture. Non-displaced fractures can be treated with immobilization, while displaced fractures may require open reduction and internal fixation with the use of plates, screws, or K-wires. Intra-articular fractures of the metacarpal head can be particularly challenging to treat and may require more complex surgical techniques.<br /><br />Dislocations of the metacarpophalangeal (MCP) joint can occur in various directions and may require closed reduction or open reduction and fixation. Thumb MCP joint injuries, particularly ulnar collateral ligament (UCL) injuries, are common and can be treated with nonoperative management or surgical techniques such as ligament reattachment or tendon grafting.<br /><br />In summary, the treatment of fractures and dislocations of the fingers and hand depends on the specific type and severity of the injury. A thorough assessment and careful consideration of the available treatment options is necessary to achieve optimal outcomes.
