Sprengel's Deformity

Topic updated on 02/17/15 12:16pm
  • Congenital condition with a small and undescended scapula often associated with q
    • scapular winging
    • hypoplasia
    • omovertebral connection between superior medial angle of scapula and cervical spine (30-50%)
  • Epidemiology
    • incidence
      • most common congenital shoulder anomaly in children
    • location
      • bilateral in 10-30% of cases
  • Associated diseases
    • Klippel-Feil (approximately 1/3 have Sprengel deformity)
    • congenital scoliosis
    • upper extremity anomalies
    • diastematomyelia
    • kidney disease
  • Osteology
    • scapula consists of
      • body
      • spine
      • acromion 
      • coracoid process
      • glenoid
  • Articulations
    • AC joint is the only true diarthrodial articulation of the scapula
  • Muscles
    • muscles that insert on medial border of scapula
      • levator scapulae 
      • rhomboids major and minor 
      • teres major
        • small portion just proximal to inferior angle
      • latissimus dorsi
        • small slip of origin at inferior angle
  • Symptoms
    • often referred for evaluation of scoliosis 
  • Physical exam
    • high riding medially rotated scapula
    • loss of long medial border
    • equilateral triangle like shape
    • shoulder abduction most limited due to loss of normal scapulothoracic motion and glenoid malpositioning q
    • forward flexion limited as well
  • Nonoperative
    • observation
      •   indications
        • no severe cosmetic concerns or loss of shoulder function
  • Operative
    • surgical correction
      • indications
        • severe cosmetic concerns or functional deformities (abduction < 110-120 degrees)
        • best to perform surgery from 3 to 8 yrs of age
        • risk of nerve impairment after the age of 8
      • pre-operative planning
        • MRI to identify omovertebral bar
      • procedures
        • Woodward procedure
          • detachment and reattachment of medial parascapular muscles at spinous process origin to allow scapula to move inferiorly
          • modified Woodward includes resection of superior pole scapula in conjunction with surgical descent
        • Schrock, Green procedure
          • extraperiosteal detachment of paraspinal muscles at the scapular insertion and reinsertion after inferior movement of scapula with traction cables
        • Clavicle osteotomy
          • in conjunction with above procedures for severe deformity to avoid brachial plexus injury
        • Bony resection 
          • extraperiosteal resection of scapular prominence alone if cosmetic concerns only
      • outcomes
        • Woodward and Green procedures can improve abduction by 40-50 degrees
