Persistence of the Trendelenburg sign postoperatively
| Subtype of high dislocation | Number of hips | ||||
|---|---|---|---|---|---|
| Preoperative | Postoperative* | ||||
| Positive (%) | Negative | Positive (%) | Less pronounced (%) | Negative (%) | |
| C1 | 49 (100) | – | – | 18 (37) | 31 (63) |
| C2 | 30 (100) | – | 1 (3)† | 13 (43) | 16 (53) |
* p = 0.560 for comparision using chi square test for persistence of the Trendelenburg sign for C1 and C2 type hips; †the number of postoperative positive hips is one, a value that cannot be analysed with chi square test and was excluded from the analysis.
