METHOD OF TREATING ASEPTIC NECROSIS OF SEMILUNAR BONE WITH RESECTION OF SEMILUNAR BONE AND STABILIZATION OF WRIST BONES Russian patent published in 2024 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to traumatology and orthopaedics, and can be used for treating aseptic necrosis of semilunar bone with resection of semilunar bone and stabilization of wrist bones. Conducting anaesthesia is performed. Skin is incised along back surface of hand, retainer is dissected along III tendon canal of extensors. Extensor tendons are moved aside. Joint capsule is opened; fragmented semilunar bone is removed. Arthrolysis of the wrist joint is performed. Antebrachii fascia fragment is separated from patient’s forearm, Antebrachii fascia fragment is laid on wrist bone, Antebrachii fascia fragment is sutured to triquetral bone and scaphoid bone. Layer-by-layer sutures are applied on the wound; hand and forearm are fixed with an external fixation apparatus. For this purpose, two wires are crossed in the lower one-third of the forearm, and two wires are inserted in the middle one-third. Pins drawn on the forearm are fixed and tightened in circular supports. Supports are connected to each other by rods. Two wires are delivered through bases of II-V metacarpals. Wires are fixed in semi-ring support, ring and semi-ring supports are connected by rods equipped with hinges.

EFFECT: method provides restoring the range of motion in the wrist joint in the patients with delayed progression of deforming arthrosis of the wrist joint by using low-traumatic surgical techniques aimed at restoring the ligaments stabilizing the proximal line of the wrist bones, and extrafocal hardware correction of the collapse of the wrist.
