Q

A
-
Stage 1 (0-3 months)
o Pain with active and passive ROM
o Limitation of forward flexion, abduction, internal rotation, external rotation
o Examination with the patient under anesthesia: normal or minimal loss of ROM
o Arthroscopy, Diffuse glenohumeral synovitis, often most pronounced in the anterosuperior capsule -
Stage 2 (“Freezing Stage”: 3-9 months)
o Chronic pain with active and passive ROM
o Significant limitation of forward flexion, abduction, internal rotation, external rotation
o Examination with the patient under anesthesia: ROM essentially identical to ROM when the patient is awake
o Anthroscopy: Diffuse, pedunculated synovitis (tight capsule with rubbery or dense feel on insertion of trochar -
Stage 3 (“Frozen Stage”: 9-15 months)
o Minimal pain except at end ROM
o Significant limitation of ROM with rigid “end feel”
o Examination with the patient under anesthesia: ROM identical to ROM when patient is awake
o Arthroscopy: No hypervascularity seen, remnants of fibrotic synovium can be seen. -
Stage 4 (“Thawing Stage”: 15-24 months)
o Minimal pain
o Progressive improvement in ROM
