Extending the Indications for Primary Nerve Surgery in Obstetrical Brachial Plexus Palsy

Abstract EN

Purpose.

This study identifies a small subset of patients with obstetrical brachial plexus palsy who, while they do not meet common surgical indications, may still benefit from primary nerve surgery.

Methods.

Between April 2004 and April 2009, 17 patients were offered primary nerve surgery despite not meeting the standard surgical indications of the authors.

The authors performed a retrospective analysis of these 17 patients using prospectively collected data.

Results.

This group of 17 patients were identified as having poor shoulder function at about 9 months of age despite passing the Cookie Test.

Fourteen patients underwent surgical intervention and three families declined surgery.

All patients in the operative group regained some active external rotation after surgery.

Five patients in this group have required further interventions.

Two of the three patients for whom surgery was declined have had no subsequent spontaneous improvement in active external rotation.

Discussion.

The commonly used indications for primary nerve surgery in obstetrical brachial plexus palsy may not adequately identify all patients who may benefit from surgical intervention.

Patients who pass the Cookie Test but have poor spontaneous recovery of active shoulder movements, particularly external rotation, may still benefit from primary nerve surgery.
