Key result
Transient brachial plexus palsy was associated with a higher incidence of diabetes mellitus (34.7% vs 10.2%; OR 4.68, 95% CI 1.42-16.32) compared to permanent brachial plexus palsy.
Why the study?
What are the differences in antepartum and intrapartum characteristics between shoulder dystocia-associated transient and permanent brachial plexus palsies?
Population
98 cases of shoulder dystocia-associated brachial plexus palsy from national birth injury and shoulder…
Comparison
Permanent brachial plexus palsy (cases) vs Transient brachial plexus palsy (controls)
Design
Case-control
Follow-up
at least 1 year of life (for permanent classification)

Maternal diabetes may favor transient over permanent brachial plexus palsy; this Level 4 association leaves open causality and needs prospective confirmation.
Case-Control (n=98)
Yes
What are the differences in antepartum and intrapartum characteristics between shoulder dystocia-associated transient and permanent brachial plexus palsies?
Odds Ratio: 4.68 (95% CI 1.42–16.32)
Absolute Event Rate: 34.7% vs 10.2%
Permanent brachial plexus palsy is associated with higher birth weight but lower maternal diabetes incidence compared to transient palsy, though most other characteristics do not differ.
Gherman et al. (2003) conducted a case-control in Shoulder dystocia-associated brachial plexus palsy (n=98). Transient brachial plexus palsy vs. Permanent brachial plexus palsy was evaluated on Incidence of diabetes mellitus (OR 4.68, 95% CI 1.42-16.32). Transient brachial plexus palsy was associated with a higher incidence of diabetes mellitus (34.7% vs 10.2%; OR 4.68, 95% CI 1.42-16.32) compared to permanent brachial plexus palsy.
