Kienböck's Diseases Treatment. A Novel Technique via Distal Capitate Shortening Accompanied by 3rd Metacarpal Base Fusion in Neutral Variance Ulna

Background: Since there is not a definite cause for Kienbock's diseases despite appropriate knowledge of lunate bone blood supply, so great debate about the ideal treatment protocol diseases. Objective: The aim this study to assess outcome combining distal capitate shortening and fusion base third metacarpal disease (Lichtman stage II or IIIA) with neutral ulna variance. Methods: Twenty patients 20 consecutive disease, their age mean was 26.1(SD 5.6) y. Patients were evaluated radiologically clinically including pre- post-operatively pain, (ROM) grip strength. Functional evaluation carried out using (MMWS). Results: final post-operative (MMWS) showed increasing from 17 (SD 2.5) 88.5 (SD7.3). Conclusion: technique capito-metacarpal yielded satisfactory results especially II, than in IIIA.
