Distal Radius Nonunions A Rare Entity?

Although distal radius fractures are common injuries, nonunion is extremely rare. Nonunion has been associated with increased metaphyseal comminution, concomitant distal ulna fracture, inadequate immobilization, and patient factors. Nonunion should be suspected in patients with persistent pain, limited range of motion, and worsening wrist deformity after wrist remobilization. Treatment selection depends on presence of infection, status of the radiocarpal and distal radioulnar joints, and type of prior surgical interventions. Multiple surgical techniques exist for managing distal radius nonunions including open reduction and internal fixation of the nonunion site with/without bone graft augmentation versus total wrist arthrodesis.

Automated summary

Although distal radius fractures are common, nonunion is rare. Nonunion is associated with factors such as comminution, ulna fracture, inadequate immobilization, and patient-related factors. Treatment options depend on infection, joint condition, and previous surgeries. Surgical techniques include fixation with or without bone graft, as well as wrist arthrodesis.
