SUMMARY
Two cases of paediatric radial and ulnar nerve injuries occurring at operative treatment of distal humeral epiphyseal fractures. In one case, the nerve laceration was associated with a defect, requiring reconstruction by nerve grafting. In a 2nd case, the nerve was compressed and partially damaged by implanting, followed by entrapment in the scar; release of the nerve from the scar resulted in recovery of its function. The importance of being familiar with the nerves’ course at the distal end of the humerus, as well as proper and prompt reaction to symptoms of nerve dysfunction occurring immediately after the operation was emphasised.
