Background and Objective

Late sequels of brachial plexus injuries include deficit in abduction and external rotation of the shoulder.

The aim of this paper is to present our initial experience with a clinical series of late presentation, in whom primary nerve reconstruction is not indicated.

Methods

We present our initial experience including a series of 5 cases. All patients presented a complete paralyzed shoulder. The superior part of the trapezius muscle was transferred to restore shoulder abduction, in cases where other procedures had failed or are not indicated because of latissimus dorsi palsy or late presentation.

Results

The trapezius functional transfer was able to restore shoulder abduction in all patients. After the procedure the mean active range of motion was 47 degrees. In 2 cases there was transitory shoulder rigidity. Partial humeral fracture was presented in other 2 cases, but after internal fixation, bone consolidation was achieved after 8 weeks.

Conclusions

The trapezius transfer offers minimal morbidity. It continues to be a useful tool in secondary reconstruction in late brachial plexus injuries, but our small series does not allow us to evaluate results and a longer follow up period is needed.
