Microsurgery in brachial plexus lesions

Area of Science:

• Neurosurgery
• Orthopedic Surgery
• Microsurgery

Background:

• Brachial plexus lesions can result in significant motor and sensory deficits.
• Microsurgical repair aims to restore function after nerve damage.

Purpose of the Study:

• To evaluate the effectiveness of microsurgical interventions for brachial plexus lesions.
• To compare outcomes of different microsurgical techniques.

Main Methods:

• Retrospective review of 22 patients with brachial plexus lesions.
• Analysis of outcomes following nerve transfer, nerve grafting, and neurolysis.

Main Results:

• Nerve grafting (5/6) and neurolysis (8/12) led to useful motor function recovery.
• Nerve transfers to the musculocutaneous nerve (0/4) did not achieve useful elbow flexion.

Conclusions:

• Microsurgical treatment is beneficial for upper brachial plexus lesions distal to the dorsal root ganglion.
• Nerve grafting and neurolysis are more effective than intercostal nerve transfers for restoring motor function.
