Case in brief
Two infants with brachial plexus birth injuries affecting the C5 to C8 nerve roots presented with wrist extension paralysis while retaining median nerve function. They underwent an anterior interosseous nerve-to-extensor carpi radialis brevis nerve transfer, which successfully restored wrist extension. This surgical approach provided a viable option for addressing wrist extension deficits in the context of extensive plexus injury.
Diagnostic / clinical pearl
In cases of brachial plexus birth injury with preserved median nerve function, anterior interosseous nerve transfer can effectively restore wrist extension.
