METHOD FOR RESTORATION OF FINGER EXTENSORS TENDONS AT THE LEVEL OF A DISTAL INTERPHALANGEAL JOINT (VERSIONS)

摘要

FIELD: medicine.;SUBSTANCE: invention refers to medicine, particularly to traumatology, orthopedics and surgery, and can be used for immobilisation of finger joints in subcutaneous rupture of finger extensor tendons in 1st zone. Disclosed are versions of a method of restoring hand tendon extensors at the level of a distal interphalangeal joint (1 zone). Both the first and second versions of the method of restoring hand tendon extensors at the level of a distal interphalangeal joint (DIPJ) include an anesthesia of the operated finger with application of a tourniquet and an exposure of a point of tendon damage along the DIPJ rear with a U-shaped skin incision of operated size (15×15)±5 mm. Minimal value of diastasis between the injured ends of the extensor tendon is achieved. According to the first version, physiological position II-V of hand fingers is bent in: metacarpophalangeal joint (MPJ) by 50–65°, proximal-interphalangeal joint (PIPJ) by 30–40°, DIPJ by 0–5°. According to the second version, by giving the specified physiological position to I finger by bending and ulnar deviation of the wrist joint at 10–15° with simultaneous bending of the I finger into: MPJ by 20–25°, DIPJ by 0–5°. Then, continuity of the injured extremities of the extensor muscle of the operated finger is restored by the Lange method; hemostasis is performed along the operation. Skin of the operated finger is sutured to the initial position; the tourniquet is removed from the operated finger and the operated finger is immobilized with the help of a plaster cast – splint or a thermoplastic fixation device in the specified physiological position of the fingers.;EFFECT: disclosed versions of the method enable to find a physiological position in the fingers joints, in which the injured extremity tendon ends in 1st zone maximally converge, restore the important hand function, complete volume of movements of distal finger phalanges, enhance patient's quality of life after restoration of finger extensor tendons at level of distal interphalangeal joint.;10 cl, 9 dwg, 3 ex
