Summary
Surgical excision of pisotriquetral loose bodies effectively resolves wrist pain and improves strength. Tomography is crucial for identifying these loose bodies, especially when routine radiography is inconclusive.
Area of Science:
- Orthopedic Surgery
- Hand and Wrist Surgery
- Sports Medicine
Background:
- Pisotriquetral (PT) loose bodies can cause wrist pain and dysfunction.
- Conservative treatments often fail to alleviate symptoms associated with PT loose bodies.
Purpose of the Study:
- To evaluate the efficacy of surgical excision for pisotriquetral loose bodies.
- To determine the optimal imaging modality for diagnosing PT loose bodies.
Main Methods:
- Retrospective review of eight patients who underwent surgical excision of PT loose bodies.
- Comparison of routine radiography and trispiral tomography for loose body detection.
- Analysis of surgical outcomes, including pain resolution and strength improvement.
Main Results:
- Trispiral tomography successfully identified all loose bodies, while radiography only detected them in 50% of cases.
- All patients experienced complete resolution of wrist pain and improved grip strength post-surgery.
- Simple excision was effective for loose bodies without joint degeneration; pisiformectomy was required in cases with degeneration.
Conclusions:
- Surgical excision of pisotriquetral loose bodies provides excellent symptom relief and functional improvement.
- Trispiral tomography is the preferred imaging method for diagnosing pisotriquetral loose bodies.
- Early diagnosis and surgical intervention can prevent long-term joint degeneration.
