Lecture Summary

The hand is a complex organ that is highly depended upon. As such, a good functional outcome after injury is of great importance. Rotation of a phalanx or metacarpal fracture is relatively common, and commonly missed by many clinicians. Part of the physical exam for patients with suspected finger and metacarpal injuries is a look for rotation – which is done with the MCP and PIP in flexion, and should be compared to the opposite hand. Carpal injuries are relatively less common – with the scaphoid fracture being the predominant one. Understanding of how other carpal injuries present (e.g., a scapho-lunate ligament injury, triquetral fracture) allows clinicians to appropriately consider these diagnoses at initial presentation. Distal radius fractures are commonly ‘Colles’-type (extra- articular, impacted, dorsally displaced and the distal fragment dorsally angulated). The goal is to realign these fractures and maintain the position. Other fracture patterns of the distal radius need to be appreciated as these may have a greater tendency to shift (unstable), and may require more rigorous treatment options, (including surgical considerations depending on resource availability).
