TFCC Injury
Other Names
- Triangular Fibrocartilage Complex Injury
- Triangular Fibrocartilage Complex Tear
- TFCC Tear
- Meniscus tear of the wrist
Background
- This page refers to injuries of the Triangular Fibrocartilage Complex, more commonly termed TFCC
History
- Needs to be updated
Epidemiology
- Estimated to represent between 3% and 9% of the hand-wrist injuries in athletes[1]
- Prevalence increases with age
Introduction




General
- Most common cause of wrist ulnar sided wrist pain
- Injuries to the TFCC can occur from either trauma or degeneration
- Diagnosis is based on history, physical examination and appropriate imaging
- Management is controversial and depends on acuity, type, severity of symptoms, and individual patient factors
Anatomy
- The Triangular Fibrocartilage Complex is a load-bearing structure
- Anchors on the Lunate, Triquetrum and Ulnar head
- Also includes triangular fibrocartilage disc, Extensor Carpi Ulnaris tendon subsheath, ulnotriquetral and ulnolunate ligaments, dorsal and volar distal radioulnar ligaments, meniscal homolog, and the ulnocarpal collateral ligament [4]
- Acts as a stabilizer on the ulnar side
Mechanism of Injury
- Different combinations of axial-loading, rotation and radial or ulnar deviations have been reported
- Direct trauma on the ulnar side of the wrist is a rare but existing occurrence
- Mechanical stress of the distal radioulnar joint is thought to contribute
- Sports involving axial-load and mechanical stress on the wrist
- Particularly if the axial-load is associated with rotations and radial/ulnar deviations
- Examples: tennis, padel, golf, ping-pong, baseball, javelin, etc.
Etiology: Traumatic
- Most common injury pattern is falling on a pronated, outstretched hand[5]
- Typically a load compressed on the TFCC while wrist is in ulnar deviation
- Examples include swinging a racket or bat
Etiology: Degenerative
- Repetitive pronation-supination as the axis of twisting passes through the articular disc[6]
- Repetitive axial loading on the ulnar aspect of the wrist
- Associated with ulnar variance, ulnocarpal impaction
Associated Conditions
- Ulnar Variance
- Chondromalacia of the ulna, lunate, triquetrum cartilage
- DRUJ Instability
Risk Factors

Clinical Features

History
- Wrist pain on ulnar side
- Worse with activities such as turning keys, opening doors painful
- Athletes report pain during forearm rotation, axial loading of wrist
- Patients may report dorsal radioulnar wrist instability
- Decreased handgrip strength
Physical Exam: Physical Exam Wrist
- Swelling may or may not be present
- Often tender at the ulnocarpal space
- Painful, limited forearm supination and pronation
- Tenderness mainly found at the level of the fovea
- Painful resistance of pronation and supination
- Joint sagging can be seen during rotation or load-bearing activities
- Audible and palpable “click” from the ulnar side of the wrist during forearm rotations
- Need to exclude muscle/ tendon related etiology (i.e. FCU, ECU, etc)
Special Tests
- Fovea Sign: ttp between ulnar styloid and FCU tendon
- TFCC Stress Test: pain with ulnar deviation
- TFCC Tension Test: pain with radial deviation
- Supination Lift Test: Attempt to lift table off ground with supinated hand
- Sharpeys Test: Pain with compression and rotation
- Piano Key Test: May be positive if DRUJ instability
- Press Test: Pain when lifting themselves out of an arm chair
Evaluation


Radiographs
- Standard Radiographs Wrist
- Generally normal
- Useful to evaluate for other lesions such as arthritis, fracture
- Potential findings
- Positive ulnar variance
- Bony fractures
- DRUJ Dislocation
CT
- Rarely indicated
- Useful if intra-articular fractures of the wrist are also present
MRI
- Typically with arthrogram[10]
- Up to 100% sensitive
- Sensitivity/ specificity vary depending on the resolution of the MRI machine
- Potential findings
- Articular disc lesions
- Adjacent bony edema
- Adjacent ligament tears
Ultrasound
- Needs to be updated
Arthroscopy
- Gold standard for diagnosis, most accurate
- Allows for direct visualization of anatomy
Classification
Class 1: Traumatic TFCC Injuries
- 1A: Central perforation or tear [11]
- 1B: Ulnar avulsion (w/o ulnar styloid fx)
- 1C: Distal avulsion (origin of UL and UT ligaments)
- 1D: Radial avulsion
Class 2: Degenerative TFCC Injuries
- 2A: TFCC wear and thinning
- 2B: Lunate and/or ulnar chondromalacia + 2A
- 2C: TFCC perforation + 2B
- 2D: Ligament disruption + 2C
- 2E: Ulnocarpal and DRUJ arthritis + 2D
Management

Athlete Considerations
- Clinician needs to consider
- Level of pain and movement limitations
- Type of lesion
- Severity of the injury
- Level of competition
- Timing of the injury in relation to the stage of the agonistic season, sport, and position
Nonoperative
- Indications
- First line in type 2 (degenerative)
- Acute type 1
- Discontinue offending activities
- No sport activity for 3-6 wk (depending on the severity of the injury)
- Immobilization
- Ulnar Gutter Cast, Short Arm Cast
- Cock Up Wrist Splint, Ulnar Gutter Splint
- Duration is 2 to 4 weeks
- Analgesia
- NSAIDS: either oral or topical
- TFCC Injection
- Corticosteroids
- Also consider hyaluronic acid, PRP
- Physical Therapy
Operative
- Indications
- DRUJ Instability
- Arthroscopy
- Diagnostic gold standard
- Debridement: 1A
- Repair: 1B, 1C, 1D
Rehab and Return to Play
Rehabilitation
- Post operative rehab (central lesions)
- Splint for 1 to 2 weeks
- Can then begin passive and active range of motion
- Sport specific movements around week 3
- Post operative rehab (peripheral lesions)
- Require immobilization for 2 to 6 weeks
- 6 to 8 weeks of active passive ROM, strengthening exercises
- Return to sport specific activity at 3 to 3 months
Return to Play/Work
- Driven by degree of pain
- In surgical cases, at discretion of surgeon
- Depends on degree of axial force, radioulnar deviation, rotation of wrist
- Golf can often return in 4 to 6 weeks
- Tennis, padel may take 6-8 weeks
- Boxing, gymnastics may take 8 to 12 weeks
- Return to sports can be aided by
- Taping, splinting, padded casts to reduce stress
- Not all sports allow use of these aids
Prognosis and Complications
Prognosis
- General
- Prognosis depends on the type of tear and associated injuries
- Above elbow immobilization is associated with better outcomes than short arm splinting
- TFCC tear without DRUJ instability
- Nonsurgical management lieads to complete recovery in 30% of patients at 6 months, 50% of patients at 1 year[13]
- A substantial number of patients have persistent symptoms
- Conservative treatment
- Sander et al compared conservative versus arthroscopic management and found similar outcomes regardless of lesion type[14]
- Surgical treatment[15][16]
- Generally yields good pain relief, functional improvement
- Most patients regaining grip strength and returning to work, but a minority may experience residual pain
- Concomitant injuries
- The presence of DRUJ subluxation or complete fovea tears predicts poorer outcome, need for surgical intervention[17]
Complications
- Ulnocarpal Arthritis
- Chronic ulnar sided wrist pain
- Persistant functional impairment
- DRUJ Instability
- Potentially, progression to DRUJ Arthritis
