Description
Technical Field
The utility model relates to the technical field of medical instruments, in particular to a combined clavicle far-end fracture internal fixation device.
Background
The acromioclavicular joint has important significance on the dynamics of the upper limb. It provides a 60-degree range of motion in 180-degree abduction of the upper limbs together with the sternoclavicular joint and participates in the forward flexion and backward extension movements of the shoulder joints. Therefore, people pay more attention to the treatment of acromioclavicular joint injury. A distal clavicle fracture refers to a fracture occurring at the outer clavicle end 1/3 with an incidence rate of approximately 25% of clavicle fractures. The clavicle far-end fracture is more common in young people, and the injury reason is usually medium-energy or high-energy trauma such as sports injury, traffic injury and the like; elderly patients are often caused by low-energy trauma such as falls. A common injury mechanism is a violent impact on the shoulder during a fall.
For adult fractures, the clinically common type of typing is Neer type. Based on the important effect of the coracoid clavicle on the stability of the proximal clavicle fracture block, the Neer type is divided into three types, i.e. the coracoid clavicle is displaced outside the coracoid clavicle, and the coracoid clavicle is complete, so the fracture displacement is generally light; type II, fracture of coracoid clavicle attached to a proximal fracture block, wherein the proximal fracture block is extremely unstable in the vertical direction due to loss of continuity of the coracoid clavicle; type III, intraacromioclavicular fracture with intact coracoid ligament, which is rare and generally stable, but may cause traumatic arthritis of acromioclavicular joint
The incidence of bone nonunion of displaced and unstable clavicle distal fracture is high, wherein the incidence of bone nonunion of Neer II clavicle distal fracture can reach 33 percent, proximal bone blocks are displaced upwards and backwards due to the fracture of coracoid clavicle and the traction of trapezius muscle, and distal bone blocks are displaced inwards and downwards due to the influence of the weight of upper limbs and the like, so that the fracture deformity healing and the bone nonunion are easily caused. In order to prevent the bone nonunion and pain of the fracture and obtain good curative effect, a plurality of scholars recommend surgical treatment. The surgical treatment method comprises percutaneous kirschner wire fixation, tension band fixation, coracoid clavicle reconstruction, cortical bone screw fixation, steel plate fixation, coracoid clavicle reconstruction, clavicle hook steel plate fixation and the like, and has no golden standard. At present, clinically, for the displacement fracture with large fracture block at the far end of the clavicle, the clavicle shoulder peak end is mostly fixed by a locking steel plate; if the far-end fracture block is smaller, the hook steel plate is adopted for treatment. However, the distal bone fragments are broken during the operation, and the clavicle shoulder peak end steel plate cannot meet the effect of stable fixation, so that the clavicle distal end steel plate and the clavicle hook steel plate are often prepared during the preoperative preparation, and the waste of resources is caused.
In view of the above, there is a need in the art for an internal fixation device for distal clavicle fractures that combines the features of a clavicle hook plate and a clavicle shoulder peak plate.
