Initial Treatment for Triangular Fibrocartilage Complex (TFCC) Tear
The initial treatment for a Triangular Fibrocartilage Complex (TFCC) tear should be conservative management with above-elbow immobilization for 6 weeks, as this approach has shown good outcomes in 76% of cases without requiring surgical intervention. 1
Diagnostic Considerations
Before initiating treatment, proper diagnosis is essential:
- MRI is the preferred imaging modality for TFCC tears, providing high accuracy for lesions involving the radial (central) zone of the disc 2
- CT arthrography is an alternative when MRI is contraindicated or when metallic implants might cause artifacts 2
- Clinical examination should include ulnar-sided wrist pain assessment and positive ulnocarpal stress test or ulnar grinding test 3
Conservative Management Protocol
Immobilization
- Above-elbow custom-molded thermoplastic splint is superior to short-arm splints (76% good outcomes vs. 29% with short-arm splints) 1
- Immobilization should be maintained for 6 weeks 1, 4
- Ice application during the first 3-5 days can provide symptomatic relief 5
Post-Immobilization Care
- After the immobilization period, progressive range of motion exercises should begin 5
- A directed home exercise program should be implemented 5
- Gradual return to activities as tolerated 5
Prognostic Factors
Factors associated with poor outcomes from conservative treatment:
- Presence of distal radioulnar joint (DRUJ) subluxation 1
- Complete foveal TFCC tears 1
- Short-arm immobilization instead of above-elbow immobilization 1
Factors NOT significantly associated with poor outcomes:
- Sex, age, energy of injury, hand dominance
- Manual occupation
- Ulnar variance
- Delay in initial treatment 1
Expected Outcomes and Timeline
The natural course of TFCC tears without DRUJ instability shows:
- 30% complete recovery at 6 months
- 50% complete recovery at 1 year 3
When to Consider Surgery
Consider surgical intervention when:
- Conservative treatment fails after a minimum of 6 months 3
- DRUJ instability is present 1, 3
- Complete foveal tears with poor response to initial immobilization 1
Cost-Effectiveness Considerations
From a cost-effectiveness standpoint, immobilization for 6 weeks while reserving arthroscopic debridement for refractory cases is the optimal strategy 4. This approach is preferred 97.6% of the time in cost-effectiveness analyses.
Special Considerations
For patients with TFCC tears associated with ulnar positive variance who do not respond to conservative management, ulnar shortening may be considered as a subsequent treatment option 6.
Alternative Non-Surgical Options
For patients who fail conservative management but wish to avoid surgery, a novel brace has shown promise as an alternative treatment, demonstrating functional improvement in weight-bearing tolerance and DASH outcome scores 7.
