Abstract
Aims: Distal humeral shaft fractures are difficult to treat by antegrade humeral nails. In this study we have used a new retrograde nail to treat these fractures. Methods and Material: Since 1997 we have treated 15 extra articular fractures using this device. The nail is introduced through the roof of the olecranon fossa, thus leaving the rotator cuff of the shoulder free from any iatrogenic injury. Proximal rotational stability is maintained by a unique ‘Trio Wire’, which passes through the nail and fans out in the head of the humerus. Distal rotational stability is maintained by the transverse plate. Results: In all cases early pain relief was obtained with return of shoulder and elbow functions. By 6 weeks 98% of patients could perform the majority of daily tasks. No significant complication was noted except a loss of extension of the elbow by 10–15 degrees. Conclusion: This new nail provides stable fixation of difficult distal humeral fractures, even in cases with poor bone quality. Early pain relief with a rapid return of shoulder and elbow functions denote a successful outcome of these operations.
