TFCC Tear: Causes, Symptoms And Treatment

TFCC or the triangular fibrocartilage complex is placed in the little finger of the wrist. It not only supports the small sized carpal bones but also allows the flexion, pronation, supination, deviation, and rotation of the wrist joint. The radius and the ulna (two bones of the forearm) are stabilized by this cartilaginous tissue. An injury to the TFCC may lead to dysfunction and chronic wrist pain.

TFCC Tears can be classified into two types:

Type 1 Tears- these are the traumatic tears caused by direct injury to the joint
Type 2 Tears- these are the degenerative type of tears that occur over a period of time as the body ages

Causes

Falling on an outstretched hand
Process of aging can cause wear and tear of the soft tissues. People above the age of 50 years are at a greater risk
If the wrist or arm is rotated excessively or beyond comfort level
Inflammatory diseases such as Rheumatoid Arthritis
Gout
Injuries caused while playing tennis, basketball, squash, etc.
Fractures in the wrist
If the length of the ulna is longer, it may cause more stress on the TFCC. This is called the Ulnar Impaction Syndrome

Symptoms

A clicking sound in the wrist when it is moved
Pain may felt at the base of the little finger and when the wrist is rotated
Inability to grip objects
Inflammation
Weakness in the hand and wrist

Diagnosis

The wrist may be manipulated manually by an orthopedic doctor to check for the exact location of the pain
The patient’s medical history and lifestyle activities may be analyzed
X-ray imaging may be required to check for bone damage and fractures
MRI testing may show the condition of the tissue and cartilage
Wrist arthroscopy
An injectible dye may be used to highlight lesions if any in the joint

Treatment

The following methods of treatment may be applied to treat the condition:

Use of a splint or a cast to stabilize the wrist for about 6 weeks
Straps that support the wrist may be used if the condition has not deteriorated much
Prescription of anti inflammatory medicines and pain killers
Injecting corticosteroids directly into the joint for immediate relief
Surgery may be suggested only when the condition does not improve through conservative therapy. Arthroscopic surgery may be preformed to remove the damaged tissue and cartilage structures
The torn tissues may be fixed using sutures
Surgical shortening of the ulnar bone
Ultrasound therapy may be helpful in some cases
Occupational therapy and activity modification may be required post-surgery to restore complete joint function
