Summary

This study suggests shoulder pain in young women may stem from anatomical variations in the levator scapulae muscle. These variations can lead to bursitis and pain, potentially explained by thermography findings.

Area of Science:

  • Orthopedics
  • Anatomy
  • Pain Management

Background:

  • Shoulder pain, particularly over the upper medial scapula, affects young females.
  • Symptoms often involve neck and shoulder radiation, aggravated by movements stretching the levator scapulae.
  • Previous investigations showed negative imaging, necessitating further anatomical and physiological exploration.

Purpose of the Study:

  • To investigate the underlying causes of a specific shoulder pain syndrome in young females.
  • To correlate clinical findings with anatomical variations and thermographic data.
  • To evaluate the efficacy of local steroid injections for symptom relief.

Main Methods:

  • Studied 22 young female patients with characteristic shoulder pain.
  • Performed anatomical dissections on 30 cadaveric shoulders.
  • Utilized thermography to assess heat emission and documented patient-reported pain and symptom triggers.
  • Administered local steroid injections to a subset of patients.

Main Results:

  • 82% of patients experienced pain in their dominant shoulder, radiating to the neck and shoulder.
  • Thermography revealed increased heat emission in over 60% of affected shoulders.
  • Anatomical dissections identified significant variability in levator scapulae insertion and a bursa in over 50% of shoulders.
  • 75% of patients receiving steroid injections showed partial symptom relief.

Conclusions:

  • Anatomical variations in levator scapulae insertion and serratus anterior origin may cause this shoulder pain syndrome, leading to bursitis.
  • These variations could explain trigger points, crepitation, and thermographic findings.
  • Local steroid injections offer partial relief for some patients, indicating an inflammatory component.
