METHOD OF TREATING HIP DISLOCATION IN SMALL LABORATORY ANIMALS Russian patent published in 2014 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, veterinary science, orthopaedics, namely to methods of treating a hip dislocation in small laboratory animals by means of subcutaneous fixators. An open reposition of the hip dislocation is followed by a perforation of a femoral bone, femoral neck and head and an iliac bone along a medial line at an angle to a distal line of the femoral bone with using a guide drill. A triangular-pointed stylette is removed from a guide drill sleeve and replaced by a doubled primary suture to be brought out from the femoral bone, femoral neck and head, and the iliac bone from the medial line of the iliac bone. Another intermediate suture is threaded into a loop formed thereby. The guide drill sleeve is removed from the drilled canal thereby spinning the primary and intermediate sutures. A fixing suture is inserted into a loop of the intermediate suture and drawn through a bone canal; thereafter, nylon monofibre and an orthopaedic pin are inserted into the loop from the medial surface of the iliac bone. A primary loop is drawn from the bone canal, pressed to the iliac bone so that an upper portion of the pin or monofibre extends into a greater trochanter. On the side of the femoral bone, the suture is knotted three times with the orthopaedic pin pre-inserted between the knot and bone, with the loop or double suture with the ends brought out under the skin within the grater trochanter. Then 10-14 days later, the skin within the greater trochanter is incised, and the rest is pulled out on the side of the iliac bone; then the double monofibre that retracts the suture fastened on its end, is removed with demounting the structure supporting the joint.

EFFECT: method enables eliminating the defects of the proximal hip and cotyloid cavity, recovering the spatial relationships in the hip joint by improving the methods for fixation accompanying the hip dislocation.
