| Abstract: | Eighteen patients with unilateral osteoarthrosis of the hip were investigated in a trial which involved the injection of nine with bupivacaine and nine with normal saline. All the patients completed daily pain analogue charts. Their pain, mobility and functional activity were assessed and gait characteristics analysed, once before the injection and then at three monthly intervals. All the patients recorded a decrease in pain level within two weeks of injection, but it subsequently rose to pre-injection levels. There were no other significant general improvements after the injection. A significant increase in the maximum force at toe-off for the good leg was recorded one month after the injection. However, no further significant differences were found in the gait performance of either group of patients throughout the study. It is concluded that the hip nerve regional blockade offers no useful relief to the pain of osteoarthrosis of the hip joint. |
