先天性橈骨頭脱臼について

抄録

Four patients with 6 congenitally dislocated radial heads were reported, which were associated with no anomalies in other parts of the body. The dislocation was anterior in 4 elbows, and lateral in 2. Radiological features revealed small and dome-shaped radial head, longer radius compared with the ulna and dysplasia of the capitulum humeri.
In three elbows, radial head was excised because of restricted motion and elbow joint pain. Dome-shaped radial head and articular cartilage erosion were observed. Thick fibrous tissue existed between dislocated radial head and capitulum. Three-year follow-up results were satisfactory in relieving pain and increasing motion.
