METHOD OF SURGICAL TREATMENT OF FUNNEL CHEST DEFORMATION AND DEVICE FOR ITS REALISATION Russian patent published in 2013 - IPC A61B17/56 A61B17/68 A61B17/80 

FIELD: medicine.

SUBSTANCE: group of inventions relates to medicine. Method includes making two cuts of skin and subcutaneous fatty cellular tissue on lateral surfaces of chest and formation of retrosternal tunnel. Titanium plate, consisting of permanent part and part to be removed, is used. Permanent part of plate in section has shape of a parabola, copying contour of correctly formed chest. Anterior end of permanent part is provided with projections with through holes and cuts in form of circle segment of equal diameter on both edges of plate. Protrusion on one edge is located opposite cut on the other edge of plate. Both ends of posterior end of permanent part of plate are provided with two pairs of unidirectional projections, made in form of circle segment of the diameter equal to diameter of through holes. Part of plate to be removed is introduced into tunnel and passed behind sternum. Part to be removed is partly broken after its bringing from under sternum. Permanent part of plate is brought behind sternum, with gradual correction of chest deformation as plate moves behind sternum with permanent support with projections on anterior surface of two adjacent ribs of both halves of chest. Projections of anterior end of permanent part of plate are bent upward and installed on external-lateral surface of two adjacent ribs of right half of chest. Projections, located opposite each other on different edges of posterior end of permanent part of plate, are bent in opposite directions in such a way that projection, directed downwards is located opposite projection directed upwards. Bent projections of posterior end of permanent part are installed on external-lateral and internal-lateral surface of two adjacent ribs of left half of chest. Plate is submerged into intercostals space from both sides of chest and plate is sewn to ribs through through holes on permanent part. Device for realisation of claimed method represents curved titanium plate for placement in intercostals space, consisting of permanent part and part to be removed, between which transverse saw cut to 1/4 of plate thickness is located. Permanent part in section has shape of parabola, copying correctly formed chest. Part to be removed is made in form of 1/2 part of ellipse with flattened end curved at angle 45° in frontal plane and through hole near its apex edge. Anterior end of constant part is provided with projections with through holes and cuts in form of circle segment of equal diameter on both edges of plate. Projection on one edge is located opposite cut on the other edge of plate. Both edges of posterior end of permanent part of plate are provided with two pairs of unidirectional projections, made in form of circle segment of diameter equal to diameter of through holes.

EFFECT: inventions make it possible to reduce trauma of chest deformation correction, increase reliability of fixation of sternocostal complex in correct position, improve cosmetic and functional result of treatment.
