From the Guidelines
Treatment for a dorsal radiocarpal ligament tear typically begins with conservative management, including immobilization with a wrist splint or cast for 4-6 weeks, followed by a structured rehabilitation program, as this approach prioritizes morbidity, mortality, and quality of life outcomes. The initial management should focus on pain control using NSAIDs like ibuprofen (400-600mg three times daily) or naproxen (500mg twice daily) for 1-2 weeks 1.
Key Considerations
- Immobilization is crucial in the acute phase to allow the ligament to heal properly.
- A structured rehabilitation program, starting around 6 weeks post-injury, should include progressive wrist strengthening and range of motion exercises to restore function and prevent stiffness.
- For persistent pain, corticosteroid injections such as methylprednisolone (40mg) mixed with lidocaine may provide temporary relief, but their use should be judicious and based on individual patient needs 1.
- Surgery, including arthroscopic debridement or ligament reconstruction, is reserved for cases that fail conservative treatment after 3-6 months, depending on the severity of the tear 1.
Diagnostic Approach
The diagnosis of a dorsal radiocarpal ligament tear often involves clinical suspicion and may be supported by imaging studies. While initial radiographs are crucial, they may not always show the ligament injury directly. In such cases, further imaging with MRI without IV contrast can be useful for detecting ligament injuries and assessing the need for surgical intervention 1. Ultrasound (US) can also be helpful in visualizing wrist tendons and intrinsic and extrinsic carpal ligaments, especially with dynamic maneuvers 1.
Rehabilitation and Recovery
Recovery from both conservative management and surgical intervention requires a comprehensive approach, including immobilization followed by a structured rehabilitation program. The goal is to restore wrist function, strength, and range of motion while preventing chronic instability and subsequent arthritis. The rehabilitation process can take several months, emphasizing the importance of patience and adherence to the treatment plan 1.

From the Research
Dorsal Radiocarpal Ligament Tear Treatment
- The treatment of dorsal radiocarpal ligament (DRCL) tears can be challenging, and the optimal treatment method is still being researched 2, 3.
- Arthroscopic repair of DRCL tears has been shown to be effective in ameliorating wrist pain, especially in cases of isolated DRCL tears 4.
- In cases where DRCL tears are associated with other intercarpal derangements, such as scapholunate or lunotriquetral ligament tears, the treatment outcome may be poorer 3, 4.
- The use of wrist-spanning plates and volar ligament repair has been reported to be effective in treating ligamentous radiocarpal fracture-dislocations 5.
- Platelet-rich plasma (PRP) therapy has been used to treat various medical conditions, including orthopedic procedures and sports injuries, but its effectiveness in treating DRCL tears is still limited by the availability of large randomized clinical trials 6.
Treatment Options
- Arthroscopic repair: This method has been shown to be effective in treating isolated DRCL tears 4.
- Wrist-spanning plates and volar ligament repair: This method has been reported to be effective in treating ligamentous radiocarpal fracture-dislocations 5.
- PRP therapy: This method has been used to treat various medical conditions, but its effectiveness in treating DRCL tears is still limited by the availability of large randomized clinical trials 6.
Associated Injuries
- Scapholunate ligament tears: These tears are commonly associated with DRCL tears and can affect the treatment outcome 2, 3.
- Lunotriquetral ligament tears: These tears are also commonly associated with DRCL tears and can affect the treatment outcome 2, 3.
- Triangular fibrocartilage complex (TFCC) tears: These tears can be associated with DRCL tears and can affect the treatment outcome 2, 3.
