Insights

Glenoplasty surgery improved shoulder function in children with obstetric brachial plexus palsy. The procedure enhanced range of motion and achieved glenohumeral stability in all patients.

Area of Science:

  • Orthopedic Surgery
  • Pediatric Orthopedics
  • Pediatric Neurology

Background:

  • Obstetric brachial plexus palsy (OBPP) can lead to posterior shoulder dislocation.
  • Surgical intervention is often necessary to address shoulder instability and functional deficits in affected children.

Purpose of the Study:

  • To evaluate the early outcomes of glenoplasty in children with OBPP and posterior shoulder dislocation.
  • To assess the impact of glenoplasty on shoulder function, range of motion, and stability.

Main Methods:

  • A cohort of 29 children with OBPP and posterior shoulder dislocation underwent glenoplasty.
  • Patients were followed up for a mean of 34 months, with assessments including the Mallet score and passive range of motion.
  • Mean age at operation was 5 years.

Main Results:

  • The mean Mallet score significantly improved from 8 to 12 (p < 0.001).
  • Significant improvements were observed in passive forward flexion (+18°, p = 0.017), abduction (+24°, p = 0.001), and lateral rotation (+54°, p < 0.001).
  • Glenohumeral stability was achieved in all cases, with a minimal reduction in medial rotation.

Conclusions:

  • Glenoplasty is an effective early treatment for posterior shoulder dislocation in children with OBPP.
  • The procedure leads to significant functional improvements and restores shoulder stability.
  • Further surgical intervention was rarely required.

Spinal Nerves: Plexus I

Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.

Muscles of the Shoulder01:23

Muscles of the Shoulder

The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.
Anterior Thoracic Muscles
The anterior thoracic muscles include the serratus anterior, subclavius, and...
