Classifications for Adhesive Capsulitis

adhesive capsulitis classification frozen shoulder shoulder pain

Frozen Shoulder: Lundberg Classification (Lundberg et al., 1969)

  1. Primary frozen shoulder:
  • Shoulder elevation <135 deg
  • Limitation of movement only at gleno-humeral articulation
  • Radiology normal
  • Other causes ie trauma, OA, RA, Hemiplegia etc excluded
  1. Secondary frozen shoulder:
  • Decreased range of movement following trauma or other known cause

Stages of Frozen Shoulder: Reeves Classification (Reeves, 1975)

  1. Painful stage: 10-36 weeks
  2. Stiffness: 4-12 months
  3. Recovery: 5-24 months

 

Arthroscopic stages of Frozen Shoulder: Nevasier Classification (Nevasier, 1987)

Stage 1:  Erythematous/ fibrinous synovium

  • patient presents as impingement

Stage 2:  Red, angry, thick synovium,

  • thick, contracted interval, tight joint space adhesions in the inferior fold

Stage 3:  Pink synovium

  • contracted inferior fold, tight joint space

Stage 4:  no evidence of synovitis

  •  tight inferior fold and joint

 

Four Clinical Stages of Adhesive Capsulitis (Hannafin & Chiaia, 2000)

  1. Painful stage
    • Characterized by pain and progressive restriction of movement. This phase is characterized by hypertrophic synovitis with hypervascularity, but a normal appearance of the capsular tissue.
  2. Freezing stage
    • Histologically, there is perivascular synovitis and collagen deposition.
  3. Frozen stage
    • Characterized by stiffness as a predominating symptom.
  4. Thawing stage
    • The formation of dense collagenous tissue in the capsule, associated with scar formation.
