TFCC Injuries and Possible Distal Radioulnar Joint Dislocation - Orthopedics

More Info

Understanding TFCC (Triangular Fibrocartilage Complex) injuries and their potential complications, such as distal radioulnar joint (DRUJ) dislocation, is crucial for effective management and recovery. The TFCC is a critical structure in the wrist that provides stability to the distal radioulnar joint and supports the ulnar side of the wrist. Injuries to the TFCC can occur due to trauma, such as falls or repetitive stress, particularly in activities involving heavy lifting or twisting motions.

From your description, it seems you have been experiencing significant symptoms following your injury, including increased prominence of the ulnar head (the end of the ulna bone) and difficulty with certain wrist movements. The fact that your symptoms have persisted despite resting and using a wrist brace suggests that there may be more than just a simple sprain or strain involved. The prominence of the ulnar head, especially with forearm pronation, could indicate instability at the DRUJ, which can occur in conjunction with TFCC injuries.

The MRI you had is a valuable tool for assessing the extent of the injury, including any tears in the TFCC or associated joint instability. While you await your follow-up appointment to review the MRI results, it is essential to consider the following:
1. Potential for DRUJ Dislocation: If the TFCC is significantly damaged, it can lead to instability at the DRUJ, which may manifest as the ulnar head becoming more prominent during certain wrist positions. This instability can cause pain and functional limitations, particularly with activities that require wrist rotation or gripping.

2. Management Strategies:
- Rest and Activity Modification: Continuing to avoid heavy lifting and activities that exacerbate your symptoms is crucial. While using a wrist brace can help stabilize the joint, it is also important to limit repetitive motions that may strain the TFCC.

- Physical Therapy: Engaging in physical therapy can be beneficial. A physical therapist can provide exercises to strengthen the surrounding muscles, improve range of motion, and enhance stability without putting undue stress on the TFCC.

- Injections: The use of high-concentration dextrose (prolotherapy) or PRP (platelet-rich plasma) injections may help in promoting healing of the TFCC and reducing pain. These treatments aim to stimulate the body's healing response and can be considered if conservative measures do not yield improvement.

3. Surgical Considerations: If conservative management fails and your symptoms persist, surgical options may need to be explored. Surgery can involve repairing the TFCC or addressing any instability at the DRUJ. It is essential to discuss these options with an orthopedic surgeon specializing in wrist injuries.

4. Follow-Up: It is important to follow up with your healthcare provider to discuss the MRI findings and determine the best course of action. If you have not yet scheduled an appointment, I recommend doing so as soon as possible to avoid further complications.

In summary, while TFCC injuries can be challenging, understanding the potential implications and management strategies can help you navigate your recovery. If you continue to experience symptoms or if your condition worsens, seeking further evaluation and treatment from a specialist is advisable.
