DR. DANIEL AEDO MARTÍN · MADRID
Triangular fibrocartilage complex injury
Pain on the little-finger side of the wrist when turning, gripping or loading.
01
What it is
The TFCC contributes to stability between the radius and ulna and helps transmit wrist loads. Injury may follow trauma or degenerative change.
02
Symptoms
Ulnar-sided pain, clicking and difficulty rotating the forearm or gripping may occur. Some wrists feel unstable. Nearby structures can cause similar symptoms.
03
Assessment
Examination assesses the TFCC and distal radioulnar joint. X-rays and, when appropriate, MRI help investigate the problem. An MRI finding without symptoms does not automatically require treatment.
04
Non-surgical treatment
Protection, activity modification and directed therapy may be appropriate. Injury type and instability influence whether immobilisation is needed and for how long.
05
When surgery is considered
In selected cases, arthroscopy allows assessment and treatment inside the wrist. Some tears require debridement; others need repair or reattachment. Causes of excessive loading must also be considered.
06
Recovery and follow-up
A repair needs protection while it heals and may temporarily restrict forearm rotation. Recovery differs from debridement. Restrictions and progression are discussed before surgery.
Frequently asked questions
Does every MRI tear need surgery?
No. Some tears cause no symptoms. Findings must match symptoms and examination.
Does arthroscopy mean immediate recovery?
No. Protection depends on the treatment performed, especially when tissue is repaired.
How do debridement and repair differ?
Debridement removes selected tissue; repair restores a repairable tear or attachment. They are not interchangeable and recovery differs.
Can I return to the gym or racket sports?
Returning to your activities is a goal. Loading and rotation progress according to stability and healing; discuss your sport before surgery.
Why does turning a key hurt?
It combines forearm rotation and grip, which may load the ulnar wrist. This symptom is not specific to TFCC injury.
Will I need a cast after arthroscopy?
It depends on treatment. Repair may need wrist and forearm rotation protection; debridement can follow a different plan.
