Insights

Restoring hand function is crucial for infants with obstetric brachial plexus lesions (OBPLs). Surgical repair achieved useful hand function in 69% of patients, highlighting its importance in treating flail arm injuries.

Area of Science:

  • Pediatric Surgery
  • Neurology
  • Orthopedics

Background:

  • Obstetric brachial plexus lesions (OBPLs) often require surgical intervention.
  • While shoulder and biceps function outcomes are well-documented, hand function recovery data post-nerve repair is limited.
  • Approximately 15% of infants with OBPLs experience impaired hand function.

Purpose of the Study:

  • To present a surgical strategy focused on restoring hand function in infants with OBPLs.
  • To analyze surgical methods and outcomes to identify factors influencing functional recovery.
  • To emphasize hand function restoration as a primary goal in OBPL nerve repair.

Main Methods:

  • Retrospective review of 33 patients undergoing surgery for flail arm over 10 years.
  • Nerve repair performed at a mean age of 4.4 months.
  • Analysis of 16 patients with sufficient follow-up (mean 50 months), categorized by nerve discontinuity (Group 1) versus nerve preservation (Group 2).

Main Results:

  • Useful hand function (Raimondi grade ≥3) was achieved in 69% (9/13) of Group 1 patients with complete nerve discontinuity.
  • In Group 2, where nerve grafts were limited, 33% (1/3) of patients achieved useful hand function.
  • Surgical reconstruction was directly attributed to hand reanimation in successful cases.

Conclusions:

  • Restoration of useful hand function was achieved in 69% of patients through the presented surgical strategy.
  • Prioritizing hand function restoration should be the primary goal in nerve repair for OBPL-induced flail arm.
  • Further research is needed to determine optimal surgical strategies for diverse OBPL lesion types.
