FIELD: medicine.
SUBSTANCE: invention refers to medicine, namely traumatology and orthopaedics. Wires are inserted and intersected through a head and a lower one-third of humerus. Then they are fixed in coupled semi-ring and ring bearings of an external fixation apparatus. The humerus is dissected transversally by an external linear approach along the length of a segment in wound depth within healthy tissues with removing completely the involved region and preserving a periosteum in the form of a case to form a cylindrical cavity. A hollow bed is formed in a proximal humeral fragment. Two soldered and hook-ended wires are inserted through a proximal end of the distal preserved bone. Free wire ends are delivered in a proximal direction along the axis of the resected humerus through the prepared hollowed in a lateral direction above a greater tubercle wherein they are fixed for the expected longitudinal traction to screwed distraction bolts fixed to the upper semi-ring. A narrow osteotome is used for the purpose of transversal compactotomy at min 2 cm from a free end of the distal humeral fragment with keeping the mobilised fragment coupled with the periosteum and soft tissues. The wound is closed. Starting with the 7-10th postoperative day, the distal mobilised fragment is distracted in the proximal direction at rising graduated rate varying within 1 mm for the first 2 weeks to 3-5 mm a day to replace the formed defect completely. Then the moved fragment is fixed in the proximal humerus to ensure complete regenerate change. That is followed by the common distraction with the required parameter to restore the segment length.
EFFECT: method provides reduced length of the full bone in place of the removed tumour, reduced length of the segment with maintaining performance of adjacent joints.
