Description

Olecranon morphological dissection locking method and steel plate structure

Technical Field

The invention relates to the technical field of steel plates for treating olecranal fracture, in particular to an olecranal shape dissection locking method and a steel plate structure.

Background

Olecranal fracture is a common injury of the elbow, and is often seen in adults. The olecranon is bent to protrude from the subcutaneous proximal end of the ulna. The olecranon is connected with the proximal coronal process of the ulna to form a semilunar notch, which is a deeply depressed articular surface (trochlear notch) that is the pivot for flexion and extension of the elbow joint. The trochlear notch and the humeral trochlear form a joint (ulnar joint), which is only flexible. Most of the olecranal fractures involve semilunar incisional articular surfaces, belong to fractures in joints, and need to be cut open for reduction and internally fixed during treatment, and the internal fixation has the following effects: (1) accurate restoration and recovery of smooth articular surfaces; (2) the fixation should be of sufficient strength.

At present, the common olecroanon fracture internal fixation method comprises two types of fixation of a K-type needle steel wire tension band and fixation of a steel plate. The fixation of the K-wire tension band is based on the AO tension band principle, changing tensile stress into compressive stress, closing the separated olecranon and pressurizing the fracture end. Steel plate fixation includes reconstruction plates, dissection plates, hook plates, and the like, with dissection plates being the most common. In both methods, the steel plate is selected to be optimally fixed.

The ulna olecranon dissection steel plate used at present is a steel plate strip with an arc-shaped end, a semicircular outward-extending protruding part is arranged at the front part of the steel plate strip, and the front end of the semicircular outward-extending protruding part is an elbow which is arc-shaped. The olecranon fixing steel plate mainly has the following defects in use: (1) the steel plate strip plate body is relatively flat and does not conform to the cristae anatomical morphology of the rear end of the ulna, the steel plate can only be placed on the bone surface of one side of the cristae of the rear end of the ulna in the process of implanting the steel plate, and the maximum tension side of the ulna is the cristae side of the rear end of the ulna, so that the fixation belongs to partial tension fixation, the tensile strength of the ulna on the opposite side of the steel plate after fracture fixation is lower, a single steel plate cannot provide stable fixation effect and is not firm, the fracture fixation principle of tension side fixation is not conformed, and the fracture stability and fracture healing are not facilitated; (2) during operation, the affected part belongs to the cortical bone, has high skin tension and belongs to a position which is not beneficial to suture and fixation; (3) after the fixation of the single-side steel plate is finished, the postoperative foreign body sensation is strong, and the affected part is easily stimulated to cause pain; (4) the locking or leather nail connected with the elbow is nailed to the ulnar joint, if the locking or leather nail is too short, the steel plate is not firmly fixed, and if the locking or leather nail is too long, the locking or leather nail can damage the joint.

In order to solve the above technical problem, patent No. 201721667336.9 discloses an ulna olecranon fixing device, the fixing device includes a first locking plate and a second locking plate, the first locking plate includes a head portion, a trunk portion and an arc-shaped connecting plate with two ends respectively connecting the head portion and the trunk portion, the second locking plate includes a straight plate portion and a curved plate portion extending from one side of the straight plate portion, the head portion and the curved plate portion can both fix a fracture block of the olecranon, the trunk portion and the straight plate portion can respectively fix the first locking plate and the second locking plate with the olecranon, the fixing of the olecranon under the combined action of the first locking plate and the second locking plate is more stable, and the foreign body sensation after unilateral fixation is reduced.

In the above patent, the first locking plate can only fix the fracture block of the olecranon through the locking hole on the head, and the second locking plate can also only fix the fracture block of the olecranon through the locking hole of the curved plate. This is a difference of the prior art.
