Description

Body position frame used in olecranon fracture operation

Technical Field

The utility model belongs to the technical field of medical appliances, specifically relate to a be arranged in position frame of ulna olecranal fracture art.

Background

The protuberance under the skin behind the proximal end of the ulna is the olecranon. And the anterior ulnar coronal process to form a semilunar notch. This notch just articulates with the humeral trochlear. The ulnar-humeral joint only has flexion and extension movements, and the olecranal fracture is an intra-articular fracture involving the semilunar notch. Therefore, anatomical reduction is an effective measure for preventing joint instability and preventing osteoarthritis and other complications. The olecroanon fracture is a common fracture type in clinic, is mostly generated in adults, accounts for about 10 percent of the fracture of the upper limbs of the adults, and can be caused by direct violence and indirect violence. The common causes of olecranal fracture include two reasons, 1, indirect external force: when falling down, the elbow joint is in the straight position of closing and stretching, the external force is transmitted to the elbow, and the triceps brachii muscle pulls the elbow to cause avulsion and fracture. The fracture line may be transverse or diagonal. The two fractured ends are separated; 2. direct external force: when falling down, the elbow joint straightens the elbow and touches the ground, or directly strikes the elbow, which causes comminuted fracture and no separation of fractured ends. The olecranal fracture is an intra-articular fracture, and the smooth articular surface can be ensured only by trying to achieve anatomical reduction in treatment, so that the occurrence of traumatic arthritis is reduced, and the function of the elbow joint is promoted to be recovered. At present, the main treatment modes of the olecranal fracture comprise non-operative treatment and operative treatment, but only a few literature reports that the olecranal fracture is treated by the non-operative treatment, and the operation is taken as the mainstream treatment mode at present.
