Alternatives to Triquetectomy for Ulnar-Sided Wrist Pain
For ulnar-sided wrist pathology, pursue conservative management with structured orthoses and progressive strengthening first, followed by arthroscopic debridement/repair if conservative treatment fails—triquetectomy is rarely indicated and should be reserved only for isolated triquetral pathology unresponsive to all other interventions.
Initial Diagnostic Approach
Start with plain radiographs to identify the specific pathology 1. The most common causes of ulnar-sided wrist pain requiring intervention are:
- TFCC tears (most common)
- Pisotriquetral joint arthrosis
- Ulnar styloid impaction syndrome
- Lunotriquetral ligament injuries
If radiographs are normal or nonspecific, MRI without contrast is the next appropriate study 1, 2. MR arthrography may be appropriate for suspected ligament tears, though it's not necessary as initial imaging 2.
Non-Operative Management (First-Line)
Implement a structured 5-phase rehabilitation program combining orthoses and progressive exercises 3. This approach demonstrates:
- Pain reduction from 5.3/10 to 0.5/10
- 35% improvement in wrist ROM
- 59.5% increase in grip strength
- Restoration of DRUJ stability
The program should include:
- Phase-specific orthoses for DRUJ stabilization
- Progressive strengthening exercises
- Proprioception training
- Monitoring every 3 weeks with advancement based on pain and function
This conservative approach is effective for TFCC injuries and should be attempted for 3-6 months before considering surgery 3.
Surgical Alternatives (When Conservative Treatment Fails)
For TFCC Pathology
Arthroscopic-assisted TFCC repair is the gold standard 4. This minimally invasive approach:
- Provides direct visualization of the injury
- Allows precise repair of torn structures
- Treats associated pathologies simultaneously
- Preserves all carpal bones including the triquetrum
For Pisotriquetral Arthrosis
Arthroscopic debridement, synovectomy, and thermal shrinkage through standard radiocarpal portals 5. This technique shows:
- VAS improvement from 5.3 to 0.3
- QuickDASH improvement from 36.7 to 8.5
- Can treat concurrent TFCC injuries (found in 67% of cases)
- Perform this before considering pisiformectomy, not triquetectomy
For Ulnar Styloid Impaction Syndrome
Partial ulnar styloid resection is the preferred surgical option 6. Complete styloid resection or corrective osteotomies are alternatives. The triquetrum itself is not the problem—it's the mechanical conflict with an elongated ulnar styloid.
For Lunotriquetral Ligament Tears
Arthroscopic repair or thermal shrinkage using dry or wet arthroscopy techniques 7, 8. Again, the triquetrum is preserved.
Critical Pitfalls to Avoid
Don't jump to triquetectomy: The triquetrum is rarely the primary pathology. It's typically a victim of adjacent joint disease (PT arthrosis, TFCC tears, or ulnar impaction).
Don't skip conservative management: The structured rehabilitation program shows excellent outcomes and should be attempted first 3.
Don't operate without arthroscopic evaluation: Wrist arthroscopy reveals concurrent pathologies in the majority of cases (TFCC tears in 67% of PT arthrosis patients) 5. Treating only one structure without addressing others leads to persistent symptoms.
Recognize that ulnar-sided pain is often multifactorial: Address all contributing pathologies simultaneously through arthroscopy rather than removing a carpal bone 8.
When Triquetectomy Might Be Considered
Triquetectomy would only be appropriate for:
- Isolated triquetral fracture nonunion with persistent pain after conservative treatment
- Isolated triquetral osteonecrosis (extremely rare)
- Failed arthroscopic treatments for PT arthrosis where pisiformectomy is contraindicated
Even in these scenarios, arthroscopic debridement or partial excision is preferable to complete triquetectomy, as removing an entire carpal bone disrupts wrist biomechanics and carpal stability.
