Metacarpal Fractures: Anatomy, Injuries and Treatment-METACARPAL FRACTURES

METACARPAL FRACTURES

Pdf Summary

Metacarpal fractures can often be treated without surgery using external immobilization and rehabilitation. However, surgery may be required for unstable fractures or when there is a need for early motion. Percutaneous pinning is a successful option for neck fractures and comminuted head fractures. Shaft and base fractures can be treated with pinning or open reduction and internal fixation. External fixation is used in cases with complex soft-tissue injury or bone loss. Bioabsorbable implants also hold promise for rigid fixation with minimal soft-tissue complications, but long-term data supporting their use is not yet available. Surgical techniques have evolved over time, with interventions like percutaneous fracture fixation and intraosseous wiring becoming more common. The early treatment of metacarpal fractures was limited to manipulation and casting, but the discovery of percutaneous fracture fixation opened up new possibilities. Bioabsorbable implants have the potential to eliminate the need for implant removal surgeries. Rehabilitation following metacarpal fractures depends on the location and stability of the fracture. Early motion is encouraged to prevent stiffness, although caution is advised for fractures that have a greater tendency for secondary displacement. Complications of metacarpal fractures can include stiffness, malunion, and nonunion. Overall, surgical treatment of metacarpal fractures aims to achieve stable fixation and early motion to promote better outcomes for patients.
