Summary

Nerve transfer surgery offers hope for brachial plexus palsy patients. Using regional donor nerves yields the best outcomes for functional recovery after severe traction injuries.

Area of Science:

  • Neurosurgery
  • Orthopedic Surgery
  • Reconstructive Surgery

Background:

  • Brachial plexus palsy from traction injury, particularly spinal nerve-root avulsion, causes significant patient disability.
  • Prognosis remains poor despite advances in diagnosis and microsurgical repair techniques.
  • Nerve transfer is the primary reconstructive option for spinal nerve-root avulsion.

Purpose of the Study:

  • To evaluate the efficacy of nerve transfer procedures for brachial plexus palsy.
  • To analyze the impact of different donor nerves on surgical repair outcomes.
  • To identify factors influencing the prognosis of functional recovery.

Main Methods:

  • Retrospective analysis of 37 patients undergoing 64 reinnervation procedures.
  • Utilized upper intercostal, spinal accessory, and regional nerves as donors for musculocutaneous and/or axillary nerve repair.
  • Compared functional recovery rates based on donor nerve type.

Main Results:

  • An 83.8% rate of useful functional recovery was achieved using regional donor nerves (medial pectoral, thoracodorsal, long thoracic, subscapular).
  • Spinal accessory nerve transfers resulted in a 64.3% recovery rate.
  • Upper intercostal nerve transfers yielded a 55.5% recovery rate, significantly lower than regional donors.

Conclusions:

  • Nerve transfer is a viable surgical option for brachial plexus palsy with spinal nerve-root avulsion.
  • Regional donor nerves significantly improve functional recovery rates compared to spinal accessory or upper intercostal nerves.
  • Donor nerve selection is a critical factor in optimizing surgical outcomes for brachial plexus palsy.
