Summary
Forearm malunions can impair function and cause joint instability. This case study shows how 3D planning and patient-specific instruments successfully treated complex forearm malunions with distal radioulnar joint instability in an adult.
Area of Science:
- Orthopaedic Surgery
- Traumatology
Background:
- Forearm malunions, often from trauma, can cause limited pronosupination and distal radioulnar joint (DRUJ) instability.
- Adults frequently require surgical intervention, such as corrective osteotomies, for these deformities.
- Complex multiplanar deformities present surgical planning challenges, with limited literature on concurrent DRUJ instability management.
