In the past eight years, 15 cases of old radial head dislocation were seen in our department, of which 9 were male and 6 were female. The age at injury ranged from 2 to 46 years. Five cases weren't operated on though the 4 over the age of 2 0 had dull pain on motion of the elbow joint. Ten cases had surgery. The time from injury to operation ranged from 2 months to 8 years, with the time for 7 being over one year. The radial head was reduced by wedge osteotomy at the proximal ulna in 4 cases, by annular ligament reconstruction in 2, and by both procedures combined in 4.<BR>Follow-up took place after an average of 2 years and 2 months, ranging from 4 months to 7.5 years. The radial head was redislocated in 6 cases out of the 10. Reduction was maintained in 2 cases out of the 4 in which reoperation was done; annular ligament reconstruction could not maintain radial head reducation in the other 2.<BR>Radial head reduction with wedge osteotomy at the proximal ulna with or without annular ligament reconstruction is recommended for treating old radial head dislocation.
