Abstract:
Objective: To explore the value of ultrasound scanning of the posterior capsule thickness of shoulder (PCT) and glenohumeral distance (GHD) for clinical staging of frozen shoulder (FS). Methods: Totally 100 patients with clinically diagnosed unilateral frozen shoulder were recruited. According to clinical staging standards, 51 shoulders were divided into stageFS group (freeing stage), 35 shoulders into stage Ⅱ FS group (frozen stage), 14 shoulders into stage III FS group (thawing stage), while 100 unaffected side shoulders of FS patients were taken as control group. Ultrasonic findings of the posterior capsule of shoulder and GHD were observed, while PCT and GHD of the affected shoulders and the unaffected shoulders were all measured and compared. Results: In stageFS group, the margin of the posterior capsule of the affected shoulders were clear, there was no significant difference of PCT between stage I FS group and control group (P>0.05), while GHD of the affected side shoulders were larger than that of the control group ([3.14±0.44]mm vs [2.22±0.35]mm, P<0.05). In stage ⅡFS group, the margin of the posterior capsule of the affected shoulders were blurred, and PCT of the affected side shoulders were thicker than that of the control group ([1.45±0.30]mm vs [1.05±0.25]mm, P<0.05), GHD of the affected side shoulders were smaller than that of the control group ([1.83±0.30]mm vs [2.22±0.35]mm, P<0.05). In stage III FS group, the margin of the posterior capsule of the shoulders were clearer. There was no statistical significant difference of PCT nor GHD between stage III FS group and control group (P>0.05). Conclusion: Ultrasound scanning of PCT and GHD can contribute to clinical staging of frozen shoulder.
