Apparatus for treatment through - and namyslow fractures of the humerus
(57) Abstract:The invention relates to medical engineering, in particular to a device for osteosynthesis, and can be used in the treatment of through - and namyslow fractures of the humerus. The apparatus includes proximal and distal frame in the form of threaded rods, spiegelzaal with slots with installed spokes and corner clips. Spiegelzaal made of two plates of trapezoidal shape with grooves at an angle of 35° to each other under the spokes and holes in the rod and the bolt for fixing the pins in the slots of the plates, and the distal frame open at the front surface. 2 Il. The invention relates to medical equipment, namely, devices for osteosynthesis, and can be used in the treatment of through - and namyslow fractures of the humerus.Known apparatus for the treatment of through - and namyslow fractures of the humerus, containing the U-shaped frame with rod holders, interconnected clamping screws and located in mutually perpendicular planes, cross-shaped bracket with axial and fixing screws and the screws from the hinges mounted on the U-shaped frame 
However, this apparatus is cumbersome is Italy of fragments of the humerus located in parallel spokes does not provide hard its fixation in the process of reposition, and in the period of stabilization in the device.Closest to the invention is an apparatus for treating fractures of the humerus, containing the proximal and distal frame in the form of threaded rods, the ends of which are made of angle clamps having three mutually perpendicular through holes. At each terminal mounted spiegelzaal consisting of a body of rectangular shape with grooves and installed spokes and an oval hole for the sleeve, which moves the clamping screw for fixing the spokes. Spiegelzaal equipped with two washers and two nuts for the longitudinal displacement of the rods 
However, the known apparatus does not provide rigid fixation of the bone fragments, as through spiegelzaal is only one spoke in the plane perpendicular to the axis of the humerus. The apparatus provides for the spokes in the sagittal plane of the lower third of the shoulder through the tendon-muscular education, which often leads to post-operative complications and the occurrence of contractures of the elbow joint. The device does not allow the development of movements in the elbow joint in the immediate postoperative period, as the spokes are only p in the elbow joint.The aim of the invention is providing a rigid fixation of the bone fragments and the possibility of early development movements in the elbow joint, as well as the reduction of postoperative complications.This is achieved by an apparatus for treatment through - and namyslow fractures of the humerus, containing the proximal and distal frame in the form of threaded rods located on them spiegelgasse with grooves and defined in their spokes, and corner clips, spiegelzaal made of two plates of trapezoidal shape with the slots at an angle 35aboutto each other under the spokes and holes in the rod and the bolt for fixing the pins in the slots of the plates, and the distal frame is not closed by the front surface.In Fig. 1 shows the proposed apparatus, a General view of Fig.2 spiegelzaal, General view.Apparatus for treatment through - and namyslow fractures of the humerus includes a proximal frame 1 and the distal frame 2, made in the form of rods 3 with solid cuts, connected by tie-rods 4. The rods 3 and the coupler 4 is fixed by means of nuts 5 in the corner clamps 6. The distal open frame 2 on the front surface. The rod 3 is fixed by means of nuts 7 spiced 10 at an angle 35aboutto each other under the spokes 11. The plate 9 has a hole 12 under the rod 3 and the hole 13 bolt 14, which fixes the needles 11 in the grooves 10 (see Fig.2).The apparatus is used as follows.On the shoulder of the patient unit is mounted in the assembled condition, choosing the distance between the frames 1 and 2 depending on the magnitude of the displacement of the distal fragment. In the middle third of the shoulder hold two intersecting spokes 11, which are secured in specularities 8 proximal frame 1. Through distal fragments of the humerus spend two intersecting angle 35aboutneedles 11 in the frontal plane, in a plane parallel to the axis of the segment on the inner side, which prevents trauma to the neurovascular and tendon-muscle formations. The spokes 11 are placed in the grooves 10 of the plate 9 specularities 8. Plate 9 are connected, the spokes 11 of the lock bolt 14. After the tension of the spokes 11 give the distraction between frames 1 and 2 and perform the test radiography. While maintaining the displacement of the distal fragment carry out the correction of its position by moving spiegelzaal 8 nuts 7 posterior or anterior, depending on the nature of the bias. To eliminate rotational displacement producing the presentation of fragments apparatus stabilize by zakanchivaya nuts 5 and 7.From the first day after the operation start of therapeutic exercises and physical therapy to restore movement in the elbow joint.P R I m m e R. Patient B. 10 years, the history N 113886, arrived in Nizhny Novgorod research Institute regarding stale extensionnode namesecure of fracture of the right humerus. In the hospital at the place of residence made two attempts closed manual reposition, which had no success. At the Institute 8 days after injury done osteosynthesis of the proposed apparatus. From the third day after the operation the patient was actively involved in gymnastics and after 1 week after intervention flexion in the elbow joint has reached the 60about, extension 150about. The apparatus filmed in 27 days. To the time of withdrawal and discharge the patient home movement fully restored, the x-ray ratio of fragments to meet satisfactory. In the long term after surgery (up to 5 years) deviations from the anatomic and functional status were not found.Apparatus for treatment through - and namyslow fractures of the humerus gives you the opportunity to spend two intersecting angle of the spokes through the short distal fragments of the humerus in the plane obespechivaniya tendon-muscular and neurovascular formations, that allows to avoid contractures of the elbow joint. The effectiveness of rehabilitation measures provided by the absence of barriers to movement due to the fact that the distal frame of the device open on the front surface. APPARATUS FOR TREATMENT THROUGH - AND NAMYSLOW FRACTURES of the HUMERUS, containing a frame in the form of threaded rods located on them spiegelgasse with grooves and defined in their spokes, as well as corner clamps, characterized in that spiegelzaal made of two plates of trapezoidal shape with the slots at an angle 35oone another under the spokes and holes in the rod and the bolt for fixing the pins in the slots of the plates, and one of the frames open.
