ROM after corticosteroid hip injection mean degrees (SD) | ||||
0 weeks | 2 weeks | 12 weeks | 26 weeks | |
Internal rotation | 17 (14) | 27 (20)** | 23 (18) | 22 (18) |
External rotation | 43 (18) | 43 (18) | 42 (18) | 45 (18) |
Flexion | 78 (21) | 82 (25) | 78 (25) | 77 (19) |
Abduction | 24 (11) | 25 (10) | 24 (10) | 24 (10) |
The values are means (SD) in degrees. There was no change in extension or leg length; ROM for the non-injected hip did not change significantly (data not shown). ** = p<0.01 (paired ttest).
