Abstract

Nineteen patients (16 - 49 years) with scaphoid pseudarthrosis were treated using vascularized bone autograft from medial femoral epicondyle. Mean term since scaphoid fracture made up 30.5 ± 21.2 months. In all cases avascular necrosis of the proximal fragment, scaphoid humpbach deformity and dorsal intercalated segment instability (DISI) were present. In 16 (84.2%) consolidation in the zone of scaphoid pseudarthrosis was achieved at terms from 8 to 12 weeks after operation. In 3 (15.8%) unsatisfactory results were observed. Average scapholunate angle correction made up 13°. Average force of feast and pinch grasps increased on the average by 2.5 and 1.5 times, respectively. One year after surgery the average estimation by DASH scale decreased by 9.6 points at average, from 27 to 13.4 points.
