METHOD OF COTYLOID CAVITY TRANSPOSITION DURING TRIPLE PELVIC OSTEOTOMY Russian patent published in 2011 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to traumatology and orthopaedics. It involves an osteotomy of a body of ischium and a superior pubic branch. It is followed by a high horizontal osteotomy of a body of ilium between an anterosuperior and anteroinferior iliac spine close to a wing of ilium with an acetabular pelvic fragment to be rotated and inclined. The procedure involves a cranial displacement of the acetabular pelvic fragment to be medialised thereafter. K-wires are used to fix a reached position of the cotyloid cavity. A portion of the acetabular fragment projecting to the outside is resected. The produced bone fragments are placed in diastases of the pubic and sciatic bones.

EFFECT: method provides elimination of bringing down of the acetabular pelvic fragment and its compression on a whirlbone, enabled reduction of whirlbone if observing higher dislocations.
