Brachial Plexus Palsy Because of Pavlik Harness Use: A Case Report

Case:
A 2.5-month-old girl with bilateral hip dysplasia presented for orthopaedic evaluation and began treatment with a Pavlik harness. One month after the initiation of treatment, decreased use of the left upper extremity was noted, which was consistent with a brachial plexus palsy. The Pavlik harness was discontinued, and upper extremity function fully recovered within 8 weeks.
Conclusions:
The Pavlik harness is an effective treatment for hip dysplasia with a low-risk profile. This case serves to remind clinicians of the risk for upper extremity traction injury when a Pavlik harness is used in patients who are large for their chronological age.
