Plate fixation of Osteosynthesis for fractures of the proximal humerus.That has a First elongated Part widens at one end and there is a second part of Greater width than the first; The two parts are internally threaded holes,To give stability to the fixed Angle screws.

摘要

The Osteosynthesis Plate used for fixation of fractures of the proximal humerus.Part comprises a handle (1) whose length is greater than its width X, and a Spoon shaped part (2) whose width greater than the width of Part x of the handle (1).Part of the handle (1) and the Spoon shaped part (2) is a common central longitudinal AXIS (3) and are united by interposition of a transition zone (26).In the part of handle (1) and also in the shape of bucket (2) have been practiced in each of the Parties at least two Holes (9, 10, 16, 17, 24) for screw.At least one of the screw holes (24), in the form of handle (1) has an internal thread (28), at least in part,A slot type Cradle or partially surrounding.At least some of the holes for screw (9, 10, 16, 17) in the form of Spoon, (2) presents a threaded interior, (27), at least in part,A slot type or partially surrounding Cua. The passage of Internal Threading (27, 28) or Slots type cua, partially surrounding, is in the range from 0.5 mm to 1, 1 mm.With It is possible to obtain a osteosisntesis angularly Stable.The Essential advantages of these plates consist of Osteosynthesis in the angular stability of holes for screws in combination with whose Head has Screw ThreadThe Easy Handling, The optimal Anatomical adaptability to the bone, and the absence of interference with the relevant Anatomical structure of proximaldel Humer
