The transgluteal approaches to the hip

Summary

The transgluteal approach to the hip, first described by Bauer et al. [1] in 1979, has since become a recognized routine method. Its longitudinal incision of the fibers of the gluteus medius and minimus and the vastus lateralis muscles takes advantage of the tendinous junction of these muscles over the greater trochanter. This paper describes the modifications of the transgluteal approach described in the literature and compares them to the original procedure. In 52 hip specimens, including attached muscles, the insertions and different variations of the junction of the gluteus medius, minimus and vastus lateralis muscles over the greater trochanter are described and statistically analysed. In 59.6% of all specimens there proved to be a united tendinous junction of all the muscles referred to above, while in 40.4% autonomous insertions of the gluteus medius and/or gluteus minimus were seen. In accordance with the anatomical results, the form of incision described by the original authors can be considered the most favourable. In roughly one-third of all hip operations, autonomous insertions of gluteus medius and minimus must be taken into account, since otherwise total or partial upward displacement of the autonomous muscle insertions could occur.
