METHOD OF PREVENTING DISLOCATION OF HIP JOINT ENDOPROSTHESIS Russian patent published in 2010 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, in particular to orthopedics. Longitudinal to hip axis section of wide hip fascia in the middle of greater trochanter is carried out. Joint capsule is dissected on intertrochanteric line in L-like way from the base of femoral neck along its upper edge to upper posterior edge of acetabulum. After dislocation and osteotomy of femoral neck endoprosthesis is installed. After that posterior part of capsule is sewn with its upper-anterior part by means of Z-like sutures. Tendons of short rotators are fixed with double tendon sutures and 2-3 holes are formed in great trochanter, and one hole is formed in trochanteric fossa. If in greater trochanter 2 holes are formed, line on which they are located must cross hip axis at acute angle, of 3 holes are formed, they are located in such way that they form isosceles triangle whose apex is directed to trochanteric fossa Sewn capsule is fixed with ligatures passed through holes in greater trochanter, double tendon sutures being passed through hole in triochanteric fossa. After that in position of external rotation and maximal abduction of extremity, knots are tightened on the surface of greater trochanter.

EFFECT: method ensures reduction of traumaticity and elimibnation of possibility to displace endoprosthesis head due to strengthening hip joint capsule.
