Restoration of Hand Function in Birth Brachial Plexus Injury

Area of Science:

• Orthopedics
• Pediatric Surgery
• Neurology

Background:

• Birth brachial plexus palsy (BBPP) often results in significant upper limb functional impairment, impacting hand use.
• While primary nerve reconstruction has advanced, many patients need secondary interventions for optimal hand function.

Purpose of the Study:

• To evaluate surgical strategies for restoring hand function in BBPP.
• To emphasize the importance of intervention timing, nerve transfer options, and reconstructive techniques.

Main Methods:

• Comprehensive review of direct root transfers and secondary tendon transfers.
• Analysis of sensory re-education and long-term functional outcomes.
• Evaluation of surgical interventions for BBPP.

Main Results:

• Early nerve reconstruction, especially nerve transfers to the lower trunk or medial cord, yielded superior functional recovery within the critical motor endplate viability period.
• Secondary tendon and free muscle transfers effectively improved grasp, pinch, and intrinsic hand function in patients with persistent deficits.
• Targeted nerve transfers enhanced protective sensation, a crucial factor for overall hand utility.

Conclusions:

• Optimizing hand function in BBPP necessitates a multimodal, individualized approach.
• Early nerve surgery offers the best chance for meaningful recovery, with secondary procedures refining outcomes.
• Understanding the interplay between motor and sensory recovery is vital for maximal functional restoration.
