RU1828747C - Method of treatment of semilunar bone inveterate dislocation - Google Patents

Abstract

Application: in traumatology and orthopedics. Purpose: reduction of the lunar bone, Method essence: knitting needles through the forearm bones, metacarpals and distal row of wrist bones, fix them in the external fixation apparatus, carry out the distraction of the wrist joint, eliminate the displacement, bring the reponent needle to semilunar bone, pressure on the bone at the same time move it to the anatomically correct position. It poses. effect: it is possible to correct chronic dislocations conservatively.

Description

The invention relates to medicine, in particular to traumatology and orthopedics, to methods of treatment using external fixation devices.

The purpose of the invention is reduction of the lunar bone.

The method is carried out as follows.

Mount the device in the following order:

- conduct 2 spokes in the proximal third of the bones of the forearm (one spoke through both bones of the forearm, the second only through the ulnar bone),

- 1 spoke is carried in the frontal plane through the distal third of both bones of the forearm,

- conduct 1 needle through the heads of II-IH-IV metacarpals and one spoke through the distal row of bones of the wrist, including the capitate,

-assemble the external fixation apparatus of 4 rings with fixing the spokes in the outer rings of the apparatus.

Distraction in the wrist joint is carried out by moving the distal ring of the apparatus. The spokes drawn through the distal third of the forearm and the bones of the wrist are convexly tensioned in a direction that mutually converges the axis of the bones. From the palmar surface in the direction of the posterior horn of the lunate bone, a reponor needle is inserted under the capitate bone. After a turn of the lunar bone, the distraction in the radial-wrist joint is removed in order to press the lunar bone in the repaired position of the capitate bone. The repository needle is removed. The external fixation apparatus is removed after 3-4 days and a plaster cast is applied.

Clinical example.

Patient T., 33 years old, trauma on 02.25.88. He was admitted on 05.16.88 with the diagnosis: chronic perilunar dislocation of the left hand, fused with a fracture of the radius in a typical place. 05/17/88, the external fixation apparatus of Kalnbers from two rings was superimposed, while 1 spoke was drawn through the bases

II-V of the bony glands and 2 spokes - through the distal metaphysis of the bones of the forearm. Within 2 weeks, dist.activation of the wrist joint was performed. 05/31/08, a needle was introduced percutaneously with an emphasis on the lunate bone with the aim of setting it under the capitate bone. Dislocation is corrected.

2. Patient R., 39 years old, injury 10.06.88, was admitted on 06.22.88, with a diagnosis of chronic dislocation of the lunar bone. Three attempts were made to correct the dislocation in a closed way. On June 28, 88 (18 days after the injury), Kalnberz AVF was superimposed from 2 rings, with 1 spoke drawn through the bases of II-V metacarpal bones and 2 knitting needles in the middle third of the forearm bones. Held a gradual extension of the wrist joint during the day and 06/30/08, v

closed by pressing the deposition needle on the bone, the lunate bone was reduced under the capitate bone. AVF was removed after 5 days, followed by the application of a gypsum tire. Dislocation is corrected. SUMMARY OF THE INVENTION A method for treating a chronic dislocation of the lunate bone of the hand by drawing knitting needles through the bones of the forearm, metacarpals and distal row of bones of the wrist, securing them in an external fixation apparatus, eliminating the wrist joint with removal of displacement, characterized in that / for the purpose of repositioning of the lunar bone, the reponitor needle is brought to the lunar bone, and pressure on the bone simultaneously moves it to the anatomically correct position.
