| Background: The exact etiology of Kienböck’s disease or lunate avascular osteonecrosis hasn’t been elucidated yet but it has been shown that progressive loading leads to increased collapse of the lunate. Negative ulnar variance has been postulated to be more predisposing to this disease. The aim of this work was to evaluate the functional, clinical and radiological outcome of scaphocapitate fusion in the treatment of management of Kienböck’s disease. Methods: This study was conducted including twenty patients with keinbock’s disease. All patients will attend at the outpatient clinic of orthopedic surgery department at Benha university hospital. Results: The average age of patients in this study ranged from 21 to 55 years. Most of our patients were manual workers, 1o patients were heavy manual workers, and five housewives were from country-side with daily heavy manual works. According to Mayo score system, the results obtained after six months follow up were encouraging. The results of treatment of 20 patients were excellent in 6 patients [30%], good in 10 patients [50%], and fair in 4 patients [20%]. As regards pain, in this study 14 patients [70 %] had mild pain after performing stressful activities and 6 patients [30 %] had moderate pain . In this series, the mean grip strength improved from 38.7% of the normal side preoperatively to 72.6% of normal side postoperatively. In this series, the postoperative extension of the wrist averaged 42.9 º ±1.5 [range: 40-45º], and the postoperative flexion of the wrist averaged 42.7 º ±2.4 [range: 36–46º]. All patients had a functional range of motion for their needs. We did not have any non-unions in our series. Conclusion: Scaphocapitate arthrodesis achieved a high rate of satisfactory clinical and radiological results with minimal complications and preserves carpal height. DASH scores indicate that scaphocapitate fusion produces minimal to mild disability. Most patients return to their work and daily activities despite some residual pain. The SC arthrodesis is a good option for the treatment of stage II and IIIa Kienböck’s disease. | ||||
