No study has investigated the relationship between the findings of
contrast-enhanced magnetic resonance imaging (CE-MRI)
and the joint volume of the
shoulder, which has been considered the standard reference for diagnosis of
adhesive capsulitis (AC). OBJECTIVE: To investigate the relationships among the
capsulo-synovial thickness measured by CE-MRI, joint volume, and passive range of
motion (ROM) in patients with AC. DESIGN: This was a retrospective study.
SETTING: The study took place at an institutional practice. PATIENTS: Medical
record of 103 patients (46 male and 57 female), who were treated with
sonographically guided intra-articular injection with diagnosis of AC and
underwent CE-MRI to rule out other concomitant shoulder disease, were
retrospectively reviewed. METHODS: Passive ROM and glenohumeral joint (GHJ)
volume were measured before and during sonographically guided injection. The
thickness of the enhancing portion of the capsulo-synovium was measured at the
axillary recess and rotator interval on CE-MRI. MAIN OUTCOME MEASUREMENTS: The
relationship among the thickness of the enhancing portion on CE-MRI, GHJ volume,
and passive ROM was analyzed using the Pearson correlation coefficient. RESULTS:
Capsulo-synovial thickness measured by CE-MRI at the enhancing portion of the
axillary recess inversely correlated with GHJ volume (rho = -0.444, P < .001),
whereas at the rotator interval, this finding was not observed. At the axillary
recess, the capsulo-synovial thickness inversely correlated with abduction (rho =
-0.400, P < .001), forward elevation (rho = -0.378, P < .001), and external
rotation (rho = -0.297, P < .01), but at the rotator interval, such statistically
significant correlations were not shown. CONCLUSION: The capsulo-synovial
thickness measured by CE-MRI at the enhancing portion of the axillary recess
could represent obliterated joint capacity and clinical impairment (restricted
passive ROM), which could help in diagnosing AC and in differentiating other
shoulder diseases that may mimic this condition. LEVEL OF EVIDENCE: III.
