Significance of the Trendelenburg test in total hip arthroplasty. Influence of lateral approaches.
The effects of lateral approaches to total hip arthroplasty on abductor weakness and limp were studied in 264 patients with primary osteoarthritis. The Hardinge approach was used in 82 patients, the transtrochanteric approach in 94, and the Liverpool approach in 88. There was no difference in functional level, range of movement, and limp among three lateral approaches. There was no increase in Trendelenburg gait after the Hardinge or Liverpool approach compared with the transtrochanteric approach. It is evident that the Trendelenburg test is a useful part of clinical examination if performed and interpreted correctly.
