Medial wrist pain

The Triangular Fibrocartilage Complex (TFCC) is a crucial structure in the wrist that plays a vital role in wrist stability and function. When the TFCC becomes injured, it can lead to pain, limited mobility, and functional impairment.

Anatomy of the TFCC

The TFCC is a cartilaginous structure located on the ulnar side of the wrist, bridging the ulna bone to the wrist's carpals. It is composed of various ligaments, tendons, and cartilage, including the triangular fibrocartilage disc, the ulnar collateral ligament, and the meniscus homologue. The TFCC's primary function is to stabilise the ulna and support the wrist's load-bearing capacity.

Causes of TFCC Injury

TFCC injuries can result from various causes, including:

  1. Acute Trauma: A fall on an outstretched hand, a forceful twist of the wrist, or a direct blow to the wrist can damage the TFCC.

  2. Repetitive Strain: Activities that involve repetitive wrist motion or heavy lifting can gradually wear down the TFCC, leading to injury over time.

  3. Aging: As we age, the TFCC may naturally degenerate, making it more susceptible to injury.

  4. Arthritis: Conditions like rheumatoid arthritis and osteoarthritis can affect the TFCC, making it more prone to injury.

  5. Instability: Chronic instability in the wrist joint can put increased stress on the TFCC, increasing the risk of injury.

Common Symptoms of TFCC Injury

TFCC injuries can manifest in various ways, with symptoms that may include:

  1. Pain: Pain along the ulnar side of the wrist, which may be sharp, aching, or throbbing, is a hallmark symptom of TFCC injury.

  2. Swelling: Swelling around the wrist joint may occur, especially after trauma.

  3. Clicking or Popping Sensation: Some individuals may experience a clicking, popping, or snapping sensation when moving the wrist.

  4. Weakness: Grip strength may diminish due to TFCC injury, making it challenging to perform everyday tasks.

  5. Limited Range of Motion: Decreased wrist mobility and difficulty rotating the forearm are common complaints.

  6. Instability: A sense of wrist instability, where the wrist feels loose or gives way, can be present.

Diagnosis of TFCC Injury

Diagnosing a TFCC injury typically involves a combination of:

  1. Medical History: A thorough review of the patient's history, including any recent traumas or repetitive wrist activities.

  2. Physical Examination: A healthcare provider will perform a physical examination, including assessing for tenderness, swelling, range of motion, and stability of the wrist.

Treatment Options for TFCC Injury

The treatment of TFCC injuries depends on the severity and type of injury, as well as the patient's overall health. Common treatment options include:

  1. Conservative Management: This may involve rest, splinting or bracing, and physical therapy to reduce pain, improve strength, and restore wrist function.

  2. Medications: Nonsteroidal anti-inflammatory drugs (NSAIDs) may be prescribed to manage pain and inflammation.

  3. Rehabilitation: Physical therapy exercises and stretches are crucial for regaining wrist strength and range of motion.

  4. Lifestyle Modifications: Patients may be advised to make ergonomic changes to their workstations or modify activities that put excessive stress on the wrist.

A TFCC injury can be a painful and debilitating condition that affects wrist function and quality of life. Early diagnosis and appropriate treatment are essential for managing TFCC injuries effectively. If you experience symptoms suggestive of a TFCC injury, seek prompt medical attention to determine the best course of action for your specific condition. With proper care and rehabilitation, many individuals can regain wrist function and resume their daily activities.
