Summary
This surgical technique widens the lunate cavity to relieve wrist stress, showing excellent results in most patients. It is effective for various ulnar variances and even some deformed lunates, excluding cases with arthritis.
Area of Science:
- Orthopedic Surgery
- Hand and Wrist Surgery
- Biomechanics
Background:
- Excessive stress on the lunate cavity can lead to wrist pain and dysfunction.
- Ulnar variance and lunate deformities are common factors contributing to wrist discomfort.
Purpose of the Study:
- To evaluate the efficacy of a specific surgical procedure for widening the lunate cavity.
- To assess the outcomes of this procedure in patients with varying degrees of ulnar variance and lunate morphology.
Main Methods:
- A dorso-lateral surgical approach was employed.
- Resection of 3 to 5 millimeters of tissue was performed to widen the lunate cavity.
- Outcomes were assessed in a series of 17 patient cases.
Main Results:
- Excellent results were achieved in 12 cases, with good outcomes in 2.
- Fair results were reported in 1 case, and poor results in 2 cases.
- The procedure demonstrated effectiveness in cases with significant ulnar variance and normal or deformed lunates.
Conclusions:
- Widening the lunate cavity via a dorso-lateral approach is a viable procedure for relieving wrist stress.
- The technique shows a high success rate, even in cases with deformed lunates, making it a valuable option for wrist pain management.
- Indications can be extended beyond significant ulnar variance, excluding only cases with additional arthritis.
