Posterior “Open Book” approach for type 1 internal hemipelvectomyKeywords: Hemipelvectomy approach,pelvic reconstruction technique Abstract: Internal limb-sparing hemipelvectomy is currently the preferred surgical option for resection of pelvic tumours. Obtaining an acceptable functional outcome through the standard ilioinguinal or iliofemoral incisions, only compounds the already challenging dissection, resection and reconstruction of these extensive en-bloc extirpative oncologic operations. We describe a novel surgical approach to the lateral pelvis that minimises injury to the gluteal muscles, spares the gluteal vessels and provides a broad yet shallow operative field conducive to microsurgery with sizeable vasculature in close proximity to facilitate any microsurgical reconstruction. Access to the ilium and sacrum for Enneking Type 1 and Type 4 resections respectively is obtained by reflecting a skin and soft tissue flap anteriorly while the gluteal muscles are reflected posteriorly and inferiorly. This technique minimises the amount of tissue reflected in any particular direction, therefore, providing a broad and shallow operative field which benefits the orthopaedic oncologic surgeon and the plastic reconstructive surgeon. The “posterior open-book” approach offers a promising alternative to the standard ilioinguinal or iliofemoral incisions for internal limb-sparing Type 1 hemipelvectomies while also optimising the exposure for subsequent reconstructive procedures
