Clinical results of shoulder manipulation under ultrasound-guided cervical nerve root block for frozen shoulder in patients with diabetes

BACKGROUND: We investigated clinical results of manipulation under ultrasound-guided cervical nerveroot block (MUC) in frozen shoulder (FS). METHODS: FS was defined refractory to conservative treatment and ≦100° in passive forward flexion. 15 shoulders were diabetes mellitus (DM) group and 81 were non-DM group. We evaluated ROM, JOA scores, Constant Shoulder Score, and UCLA scores pre and post-MUC. RESULTS: Although there were significantly improved the forward flexion, internal rotation, JOA scores, Constant Shoulder Score, and UCLA scores between pre and post-MUC in both groups, external rotation after MUC in DM group were significantly inferior to those in non-DM group.
