Huckstep intramedullary nailing for non-union of humeral shaft fractures
1Department of Orthopaedic and Trauma Surgery, Royal North Shore Hospital, St Leonards, New South Wales, Australia.
Background:
Various techniques of internal fixation for non-union of humeral shaft fractures have been attempted, leading to union rates of between 50 and 90% with persisting non-union causing pain and disability. Some of these techniques have led to shoulder and elbow dysfunction.
Methods:
Eight patients treated with Huckstep nail fixation for humeral shaft non-union were reviewed and the rate of union was determined. Elbow and shoulder function were assessed as well as the presence of pain or disability.
Results:
Union was achieved in seven of the eight patients (87.5%). Four patients had occasional mild pain after union. All patients achieved good arm function. Average shoulder abduction was 157 degrees and flexion 151 degrees excluding one patient with antecedent advanced osteoarthrosis of the gleno-humeral joint. No patient experienced any permanent neurological deficit.
Conclusions:
Huckstep nail fixation achieved union rates comparable to or higher than the other techniques of internal fixation for non-union of humeral shaft fractures. Unlike the various methods of closed nailing, Huckstep nail fixation is not associated with shoulder and elbow dysfunction. It should be considered as a therapeutic option in humeral shaft fracture and non-union, especially where the fracture site needs to be opened.
