Clinical Causes: Direct blow or trauma to the hand, such as being hit with a heavy object. Falls onto an outstretched hand, especially from a significant height. Motor vehicle accidents causing blunt force injury. Sports-related injuries, like during contact sports or falls. Crush injuries that exert excessive force on the hand.

Key Symptoms: Sudden pain in the affected hand, particularly near the base of the fourth metacarpal. Swelling or bruising around the back of the hand. Deformity or unnatural positioning of the hand or finger. Difficulty moving the ring finger or gripping objects. Tenderness when touching the affected area. Potential numbness or tingling if nerves are affected.

Diagnosis Path: A healthcare professional will conduct a physical examination to assess for deformity, swelling, and tenderness. To confirm the fracture and evaluate its displacement, diagnostic imaging such as X-rays is typically performed. The X-ray images help visualize the location, extent, and nature of the fracture, guiding appropriate treatment options.

Treatment Protocols: Treatment for a displaced fracture of the base of the fourth metacarpal often involves realigning the bone fragments to restore proper anatomy. This process, called reduction, can be non-surgical (closed reduction) performed by manipulating the bones manually, or surgical if the fracture is severely displaced or unstable. Following reduction, immobilization with a cast or splint for several weeks is common to allow healing. In some cases, surgical stabilization with pins, screws, or plates may be necessary. Pain management, elevation, and hand therapy exercises are typically recommended post-treatment to regain strength and mobility. Recovery time varies depending on the severity of the fracture and the individual’s overall health.
