股関節鏡視下手術における大転子を骨ランドマークとしたポストレス牽引下での外側から内側への遠位から近位への縦断的関節包切開術

Hip arthroscopy is an established treatment for femoroacetabular impingement syndrome, with demonstrated long-term efficacy. However, the deep-seated anatomy of the hip joint and its complex periarticular structures pose significant challenges for achieving safe capsulotomy and adequate intra-articular exposure. We describe a technique using the greater trochanter as an anatomical reference point to perform an outside-in, distal-to-proximal longitudinal capsulotomy under postless traction.
