Modified technique in the dorsal approach in total hip arthroplasty.

A modified dorsal approach with osteotomy of a bone shell with the attached short external rotator muscles which are resutured, is described. The advantages have been less dislocations, less sciatic nerve injuries, and an increased operative access. There have been no disadvantages, as increased bleeding or periarticular calcification. The dorsal approach can be used for all conventional total hip arthroplasties and the reported modification seems to be an advantage.
