Outcome of management of Kienböck disease by limited carpal fusion

Authors

Abstract

Objectives
To evaluate the clinical and radiological outcome of Kienböck’s disease treatment by scaphocapitate fusion in 20 patients.
Background
Kienböck’s disease remains a difficult entity to treat till understanding the etiology and natural history of the disease. Treatment will continue to be based on trails to decrease load across the lunate or revascularizing it.
Patients and methods
This study was retrospectively performed on 20 patients, with age of 19–59 years. All of the patients presented with Kienböck disease grades II and IIIa and with no evidence of arthritis. They were treated with scaphocapitate arthrodesis using the dorsal approach. The mean follow-up period was 6 months. Complications and adverse events were recorded.
Results
The clinical results were classified on subjective base and were graded as excellent outcome in six (30%) patients, good in 10 (50%) patients, and fair in 4 (20%) patients.
Conclusion
Scaphocapitate arthrodesis is a good procedure that mechanically decompresses the lunate and prevents progressive carpal instability with minimal complications.
