Summary

Brachial plexus surgery outcomes show good recovery in 58% of patients. Nerve grafting and neurolysis yielded better results than neurotization, especially for open injuries and timely intervention.

Area of Science:

  • Neurosurgery
  • Orthopedics
  • Rehabilitation Medicine

Background:

  • Brachial plexus injuries significantly impair motor function.
  • Surgical interventions aim to restore function after brachial plexus injuries.
  • Long-term outcomes of different surgical techniques require detailed evaluation.

Purpose of the Study:

  • To evaluate the motor functional recovery in patients after brachial plexus surgery.
  • To compare the effectiveness of autologous nerve grafting, neurolysis, and neurotization.
  • To identify factors influencing recovery, such as injury type and timing of intervention.

Main Methods:

  • Retrospective analysis of 52 patients undergoing 58 brachial plexus procedures.
  • Surgical procedures included nerve grafting (38), neurolysis (14), and neurotization (6).

  • Outcomes assessed using the Medical Research Council (MRC) 0-5 scale over a 2-year follow-up.

    • Main Results:

    • Overall good recovery was achieved in 58% of patients.
    • Nerve grafting (58%) and neurolysis (64%) showed good results; neurotization had poor outcomes.
    • Open injuries demonstrated better recovery than closed injuries (48%).
    • Traffic accident-related closed injuries had worse outcomes.
    • Timely intervention (nerve grafting <3 months, neurolysis <6 months) improved recovery.

    Conclusions:

    • Autologous nerve grafting and neurolysis are effective in brachial plexus surgery.
    • Neurotization appears less successful for motor functional recovery.
    • Early surgical intervention and management of open injuries are crucial for better outcomes.
