Classifications for Adhesive Capsulitis
Frozen Shoulder: Lundberg Classification (Lundberg et al., 1969)
- 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
- Secondary frozen shoulder:
- Decreased range of movement following trauma or other known cause
Stages of Frozen Shoulder: Reeves Classification (Reeves, 1975)
- Painful stage: 10-36 weeks
- Stiffness: 4-12 months
- 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)
- 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.
- Freezing stage
- Histologically, there is perivascular synovitis and collagen deposition.
- Frozen stage
- Characterized by stiffness as a predominating symptom.
- Thawing stage
- The formation of dense collagenous tissue in the capsule, associated with scar formation.
