Shoulder linked arthroplasty in patients with obstetric brachial plexus palsy can improve quality of life and function at short-term follow-up
2015
Background Patients with obstetric brachial plexus palsy (OBPP) are prone to develop degenerative shoulder disease at a younger age than the general population. To date, no reports have been published on the complexities or outcome of shoulder arthroplasty (SA) in this unique patient group. Methods We reviewed of 9 SAs in 9 patients (3 men and 6 women) with OBPP with mean follow-up 5.1 years (range, 2.6-7.6 years). Patients were a mean age of 29 years (range, 16-56 years). Patients had undergone a mean of 3 previous operations (range, 2-6). All patients underwent linked constrained SA. Results The mean Oxford Shoulder Score increased from 8 (range, 3-10) preoperatively to 21 (range, 12-32) at the final follow-up ( P P = .013) and mental health ( P = .035), and the overall physical component summary score ( P = .006). Range of motion had mild improvements. Three required reoperation (33%), comprising 1 excision of heterotopic ossification, 1 trimming of a prominent screw, and 1 deltoid rupture repair. Conclusions SA is effective at relieving pain and health-related quality of life for young patients with OBPP; however, compared with the general population, the complication rate is high and functional gains are small.
