Abstract
In this study, innovative bone replacement material was tested after complicated metaphyseal radius fractures with the affected joints. In all, 11 C 2, 11 C 3 and 3 A 3 radius fractures were treated by surgery combining an angularly stable palmar plate osteosynthesis with defect filling using nanocrystalline hydroxyapatite. Examinations were conducted preoperatively and postoperatively after 4 weeks, 12 weeks and 9-12 months. After 10.5+/-1.4 months, inclination angles of 8.7+/-1.8 degrees (dorsopalmar) and 18.8+/-2.9 degrees (radioulnar) were measured at the treated fractures, the ulnar drift was 0.6+/-1.8 mm. According to the Gartland/Werley scale, 10 therapeutic results were considered "excellent", 12 "good" and 3 "fair". An angularly stable plate osteosynthesis with metaphyseal defect filling using nanocrystalline hydroxyapatite for the treatment of A 3, C 2 and C 3 radius fractures showed satisfactory radiological and clinical results.
