SU1533676A1 - Method of endoprosthesis of kneepan - Google Patents

Abstract

The invention relates to medicine, namely to traumatology and orthopedics in the treatment of a modified patella or in replacing it with an endoprosthesis. In order to prevent arthrosis of the femoral-patellar joint, cut a non-free flap from the wide fascia of the thigh and tendons of the quadriceps, place it between the endoprosthesis and the thigh muscles, form a duplicated tape from its own patellar tendon and fix it to the front surface of the endoprosthesis and the quadriceps tendons.

Description

The invention relates to medicine, namely to traumatology and orthopedics in the treatment of diseases and injuries of the patella, the benefit of removing it and replacing the endoprotein

The purpose of the invention is the prevention of deforming arthrosis of the femoral-patellaus cvoava

The method is carried out as follows: Razoezol Payra disassembling knee joint is isolated and the modified patella is removed. From the wide fascia of the thigh and the tendons of the quadriceps muscles of the thigh, cut out a 1/3 leg thickness flap, a flap is bent under the gloom 180 ° and hemmed with silk or with lavsan in place of the defect after removal of the patella of the defect. The edge of the wide fascia is poured into the underlying muscle with catgut at the site of the taken flap. The acryl-laminated plastic is laid over the flap. ssy patella, the size and shape predusmo-Rena control of ra-

Example. Patient B., 14 years old, entered the children's department of the institute with a diagnosis of fibrosis dysplasia of the left patella. According to his image on the R-gram, an endoprosthesis was made from acryloxide plastic. 07.23.85, the Payra incision along the medial surface reveals the knee joint in layers. The modified patella is isolated and dissected as a single unit. From the wide fascia of the femur and the tendons of the quadriceps muscle of the thigh outside of the midline, an oval-shaped flap is cut with a size correspondingly formed in the patellar joint's own defect, with a leg in the area of the quadriceps tendon, including 1/3 of its thickness. The flap is rotated at a 180 ° angle and stitched with polyester seams over the defect formed after patoelektomii.

The edge of the wide fascia of the thigh at the site of the flap is hemmed to the underlying muscles. A pre-made prosthesis of the patella is laid over the fastened fascial flap and fixed with polyester stitches to the fascial bed through the holes previously formed along its edges. The leakage is also hemmed to the patellar intrinsic link and quadriceps tendon. A 1/4 cord width, 2 cm wide, is cut out from the patellar own link,; the flap leg is cut off from the link above its attachment to the tibial tubercle 1s 1 cv , i itself is deployed under ipv 181 i), 1., I have the strength of mylar with mylar somite stitches of a tlblinatcher along the entire length, a strip of south along the median surface of the prosthesis into a pre-made groove Disgular and proximal ends of the flap are fixed

They are decorated with polyester sutures to the patellar tendon proper ligament and tendon of the quadriceps muscle of the thigh. The defect of the patellar own ligament is sutured with polyester seams. The wound is sutured in layers, active drainage is left in the joint for 1 sug. The limb at an angle of 175 ° is immobilized. The back gypsum splint for two weeks, then the development of movements on the knee joint has begun. The load on the limb is allowed after three weeks.

The patient was examined by f-res 11 months after the operation, which was performed on amoch, atoric treatment after 1 Mtc g, os.- operation No complaints. The contours of the left knee joint are correct, the amplitude of movements in the joint is from 180 to 80 °. The patient walks without additional support, the gait is even. On the control of the left knee joint, the prosthesis of the patella remains in the same place, the slit of the hip. , i kneeled with a mill of uniform width.
