Intercarpal Ligament Injuries Associated With Distal Radius Fractures
1From the Department of Orthopedics and Rehabilitation, University of Iowa Hospitals and Clinics, Iowa City, IA.
Injuries to the scapholunate and lunotriquetral interosseous ligaments often accompany distal radius fractures but are hard to diagnose. Wrist arthroscopy offers accurate diagnosis, though treatment necessity for these ligament injuries remains speculative.
Area of Science:
- Orthopedic Surgery
- Hand and Wrist Surgery
- Radiology
Background:
- Scapholunate (SL) and lunotriquetral (LT) interosseous ligament injuries occur in about one-third of distal radius fractures.
- Diagnosing these ligament injuries is difficult as plain radiographs are often unreliable.
Purpose of the Study:
- To evaluate the diagnostic accuracy of wrist arthroscopy for SL and LT interosseous ligament injuries associated with distal radius fractures.
- To discuss current treatment options for these ligament injuries.
Main Methods:
- Review of diagnostic modalities for SL and LT interosseous ligament injuries.
- Discussion of treatment options including open repair and percutaneous pinning.
Main Results:
- Plain radiographs are not reliably diagnostic for SL and LT interosseous ligament injuries.
- Wrist arthroscopy is suggested as the most accurate method for diagnosing these soft-tissue carpal injuries.
Conclusions:
- The diagnosis of SL and LT interosseous ligament injuries adjacent to distal radius fractures is challenging.
- Wrist arthroscopy may be the most accurate diagnostic tool.
- The necessity of diagnosing and treating these defects is currently speculative due to an unclear natural history.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
