To evaluate the efficacy of distention arthrography (DA) alone and in combination with translational mobilization (TM) for treatment of patients with frozen shoulder (FS).
Eighty-five patients diagnosed with unilateral FS (freezing or frozen stage) were included. Forty-one patients were treated with DA and TM (group 1) and 44 patients with DA alone (group 2). Clinical assessments including visual analogue scale (VAS), Cyriax stage, and shoulder passive range of motion (PROM) including forward flexion, abduction, external rotation, and internal rotation were measured at baseline, 1 month, and 3 months following treatment.
There were no significant differences in gender, side affected, symptom duration, presence of diabetes mellitus, VAS score, Cyriax stage, or shoulder PROM between the two patient groups at baseline. Compared with baseline metrics, patients in both groups demonstrated significantly improved outcome parameters at two post-treatment time points. However, mean all shoulder PROMs were significantly greater, and mean VAS score and Cyriax stage were lower in patients treated with DA and TM than in those treated with DA alone group at two post-treatment time points. At these times, mean interval change of all outcome parameters was significantly greater with DA and TM than DA alone. No serious complications were observed following treatment in either patient group.
Compared with DA alone, DA combined with TM more effectively alleviates shoulder pain and increases PROM in patients with freezing or frozen stage FS.

Objective: MRI findings of adhesive capsulitis (AC) have been rarely documented even though the disease is a rather common disorder. To find reliable MRI parameters, we studied MRI findings of the patients with arthrographically-proven AC.
Method: Eighteen patients with AC (patient group) and eight subjects without AC (control group) were enrolled. Mean age of the former was 55.1 years and that of the latter was 41.4 years. Mean duration of the diseases in patient group was 5.9 months. Oblique coronal and axial MRI images of the shoulder were measured for the thickness of capsule and synovium around the axillary fold (TAF), volume of axillary recess (VAR), and volume of biceps tendon sheath (VBTS), which were com-
pared in both groups using unpaired t-test.
Results: TAF was significantly increased in patient group (p＜0.0001), and the thickened axillary fold greater than 5.1 mm was a useful MRI criterion for the diagnosis of AC with sensitivity of 93% and with specificity of 100%. VBTS was also significantly diminished in patient group (p＜0.05), whereas there was no significant difference in VAR between two groups.
Conclusion: TAF, especially greater than 5.1 mm, and decreased VBTS are useful MRI parameters for the diagnosis of AC of shoulder. (J Korean Acad Rehab Med 2002; 26: 177-181)
Objective: To define arthrographic findings in patients with frozen shoulder and to evaluate the therapeutic effect of arthrographic capsular distension and rupture.
Method: Thirty patients who were clinically diagnosed as frozen shoulder were enrolled. During a trial of intra-articular injection of 35 mL of fluid which contained 8 mL of 1% lidocaine, 2 mL of prednisolone (80 mg) and 25 mL of radiocontrast material, arthrographic findings and the occurrence of iatrogenic capsular tear were observed. Passive range of shoulder motion (percent of normal, %) at flexion, abduction, internal rotation, and external rotation was measured at pre- and 1 week post-injection. The therapeutic effect of the procedure was statistically analyzed by paired Student's t-test.
Results: Mean age of the subjects was 57-years-old (range: 40∼76 years) and mean duration of the symptom was 6 months (2∼42 months). A decreased joint volume of less than 10 mL (100%), poor or absent filling of the axillary recess or subscapular bursa (75.9%), nonfill of the biceps tendon sheath (37.9%), and irregularity of capsular insertion (31.0%) were typical abnormal arthrographic findings. In one week after arthrographic distension and rupture, the passive range of shoulder motion was significantly (p＜0.05) increased at flexion, abduction and external rotation, of which the range of external rotation was the most remarkably increased (mean, 23.9%).
Conclusion: Distension arthrography was useful for increasing shoulder motion in frozen shoulder, especially at flexion, abduction and external rotation.
