DEVICE FOR TREATING SHOULDER FRACTURES Russian patent published in 2014 - IPC A61B17/80 

FIELD: medicine.

SUBSTANCE: device comprises a plate element having an arch cross-section configured to be attached to the humeral bone, and a cup configured to be attached to a head of the humerus connected by a poorly concave transient portion. The plate element is provided with at least three through holes arranged along the long axis of the device with their axes directed perpendicular to the surface of the plate element. The transient portion is provided with at least one through hole arranged along the long axis of the device with its axis facing a flat end of the cup. The cup is provided with at least three pairs of through holes symmetrical in relation to the long axis of the device. Each pair of the through holes of their axis in a transverse plane of the device is symmetrical in relation to the central axis. The through holes of the plate element, the transient portion and the cup are threaded. The through holes of the plate element and the through hole of the transient portion represent two overlapped circles. An internal surface of the proximal circle of each through hole is threaded, and its diameter is less than that of the distal circle. A length of the transient portion makes at least a half of the length of the cup. The transient portion is provided with an additional pair of the through holes symmetrical in relation to the long axis of the device; their axes face the flat end of the cup with its cross point lying from the side of the cup concavity. The cup is provided in plane in the form of a rectangle and has three pairs of the through holes. The axes of the pair of the through holes closest to the flat end of the cup and their cross-point lies from the side of the cup concavity. The axes of the second pair of the through holes face from the flat end of the cup and their cross-point lies from the side of the cup concavity. The axes of the pair of the through holes closest to the transient portion face the flat end of the cup with their cross-point lying from the side of the cup concavity. One of the side edges of the cup is additionally provided with an ear with a varied position and form of the profile in the transverse plane of the device. The ear is provided with at least one threaded through hole along the long axis and perpendicular to the ear surface. The long axes of the ear in plane are perpendicular to the long axis of the device.

EFFECT: higher clinical effectiveness in treating shoulder fractures by reducing a probability of fracture of the device and higher reliability of the device fixation to the patient's humeral bone.
