Summary
Triscaphe arthrodesis can lead to painful radial styloid impingement in 33% of patients. To prevent this wrist pain, a partial radial styloidectomy is now routinely performed during the procedure.
Area of Science:
- Orthopedic Surgery
- Hand and Wrist Surgery
Background:
- Triscaphe arthrodesis is a surgical procedure to fuse the scaphoid, trapezium, and trapezoid bones in the wrist.
- Radial styloid impingement is a potential complication following this surgery.
Purpose of the Study:
- To investigate the incidence and characteristics of radial styloid impingement after triscaphe arthrodesis.
- To evaluate the effectiveness of partial radial styloidectomy in managing this complication.
Main Methods:
- Retrospective review of 93 triscaphe arthrodeses in 91 patients.
- Analysis of patient outcomes, focusing on radial styloid impingement symptoms and subsequent treatments.
Main Results:
- 33% of patients experienced radial styloid impingement, presenting with radial wrist pain or limited motion.
- Patients with prior scaphoid rotary subluxation had a higher incidence of impingement.
- 18% of patients required a partial radial styloidectomy for symptom relief.
Conclusions:
- Painful radial styloid impingement is a significant complication of triscaphe arthrodesis.
- Routine incorporation of partial radial styloidectomy during triscaphe arthrodesis may help prevent this complication.
