Splinting for Non-Displaced 3rd Metacarpal Fracture

Splint Selection and Application

• The splint should immobilize the fracture site while allowing for finger motion to prevent stiffness 1
• A standard 3-view radiographic examination should be performed to confirm proper alignment before and after splint application, as recommended by the American College of Radiology 2

Duration of Splinting and Rehabilitation

• Radiographic follow-up is recommended at approximately 3 weeks to confirm adequate healing 1
• Active finger motion exercises should be performed following diagnosis to prevent stiffness 1
• Finger motion does not adversely affect adequately stabilized metacarpal fractures 1

Treatment Considerations

• For fractures with significant displacement (>3mm), dorsal tilt (>10°), or intra-articular involvement, surgical management may be indicated instead of conservative treatment 1
