Summary
Diagnosing scaphoid union can be challenging, even during surgery. Some scaphoid fractures initially appearing united may still progress to non-union, highlighting diagnostic difficulties.
Area of Science:
- Orthopedic surgery
- Musculoskeletal research
Background:
- Scaphoid fractures are common wrist injuries.
- Non-union of scaphoid fractures can lead to long-term complications.
Purpose of the Study:
- To evaluate the diagnostic accuracy of surgical exploration for scaphoid union.
- To assess the outcomes of surgically treated scaphoid non-unions and suspected non-unions.
Main Methods:
- Surgical exploration of 14 patients with radiological or suspected scaphoid non-union.
- Intraoperative assessment of scaphoid union status.
- Postoperative follow-up to determine union outcomes.
Main Results:
- Ten scaphoids appeared united intraoperatively; 5 achieved definite union, while 5 failed (1 despite internal fixation).
- Four scaphoids showed partial union intraoperatively and all proceeded to complete union.
- Surgical assessment of scaphoid union is not always definitive.
Conclusions:
- Intraoperative assessment of scaphoid union can be unreliable.
- Further investigation or longer follow-up may be needed even after surgical exploration.
- Challenges in diagnosing scaphoid union persist.
