Summary
Wrist arthroscopy is more effective than arthrography for diagnosing ligament injuries. Many patients diagnosed with normal arthrography had injuries revealed by arthroscopy.
Area of Science:
- Orthopedics
- Diagnostic Imaging
- Surgical Procedures
Background:
- Wrist ligamentous injuries present diagnostic challenges.
- Standard X-rays often do not reveal subtle ligamentous damage.
- Accurate diagnosis is crucial for effective treatment of wrist injuries.
Purpose of the Study:
- To compare the diagnostic accuracy of triple injection wrist arthrography and arthroscopy.
- To evaluate the discrepancies between arthrography and arthroscopy in diagnosing wrist ligament injuries.
- To determine the most efficient diagnostic method for suspected wrist ligamentous injuries.
Main Methods:
- 150 patients with suspected wrist ligamentous injuries and normal X-rays were studied.
- Comparison of diagnoses obtained via triple injection wrist arthrography and arthroscopy.
- Analysis of agreement and alterations between the two diagnostic modalities.
Main Results:
- Arthroscopy identified abnormalities in 91% of patients, compared to 71% with arthrography.
- Agreement between arthrography and arthroscopy was only 42%.
- 58% of arthrographic diagnoses were altered after arthroscopy, with 80% of those with normal arthrography showing injuries on arthroscopy.
Conclusions:
- Wrist arthroscopy is a more sensitive and efficient method for diagnosing ligamentous wrist injuries than arthrography.
- Arthrography may miss significant injuries, leading to diagnostic alterations upon arthroscopic examination.
- Arthroscopy should be considered the primary diagnostic tool for suspected wrist ligamentous injuries when clinical suspicion is high despite normal imaging.
