METHOD FOR FIXING INJURED DISTAL TENDON OF BICEPS MUSCLE Russian patent published in 2025 - IPC A61B17/00 A61B17/56 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely traumatology and orthopaedics, and can be used to increase clinical effectiveness of surgical treatment of distal tendon of biceps muscle. Method involves an incision along the anterior surface of the shoulder, exposing the injured end of the tendon of the biceps muscle, suturing it with a lavsan suture with an intra-barrel tendon suture by M.M. Kazakov, using Farabeuf hooks to widen the approach. Sutures are brought out along the edges of the injured end of the tendon. Intermuscular space is palpated on an external surface of the forearm in a projection of the neck of the radial bone, and a layer-by-layer incision is made in the projection of the neck of the radial bone. Muscle fibres are stratified longitudinally. Incision is widened with Farabeuf hooks. Neck of the radial bone is visualized and the neck of the radial bone is palpated. Second hand is palpated along the sheath of the injured tendon of the biceps muscle through the approach along the anterior surface of the shoulder of the lower one-third with an emphasis on the tuberosity of the radial bone. Parallelism of proximal and distal canals extending from the radial bone neck and coming into the radial tuberosity is assessed. In the supination position of the forearm, proximal and distal canals are formed with a drill D of 2.0 mm with a drill pitch of 0.25 mm and not more than 2.5 mm. In the formed channels, from the access side along the outer surface of the forearm, wire loops are introduced, which are brought out into the incision on the anterior surface of the shoulder, to capture the sutures, sutures are brought out into the incision of the upper one-third of the forearm along the outer surface. Patient’s arm is rotated to the position of maximum supination, bent at a right angle, the injured end of the tendon is pulled to the point of separation, the sutures are tied on the neck of the radial bone.

EFFECT: method enables the patient to begin to perform passive movements to develop the joint a week after the operation, by the fourth week from the operation, the supination volumes are restored, abduction, forearm elevation to a level comparable to a healthy extremity of the patient, due to the formation of two parallel channels with an exit to the tuberosity of the radial bone, atraumatic introduction of thin wire loops for removal of ligatures in upper one-third of forearm and stretching of tendon to radial tuberosity and its fixation.
