Description
Technical Field
The utility model relates to the technical field of orthopedic implants, in particular to an acetabular lateral fracture bone fracture plate.
Background
The treatment of acetabular fractures has progressed rapidly and mortality has decreased dramatically over the past 30 years. To obtain good clinical effect in long term, anatomic reduction of acetabular fracture is the basis, and the functional yield of anatomic reduction patients is obviously higher than that of non-anatomic reduction patients. For complex acetabulum fracture, incision reduction internal fixation is the first choice of surgical treatment and is the consensus of the current medical community.
The acetabulum is a typical pestle-socket joint, which has the functions of connecting the trunk and the lower limbs, conducting the gravity of the human body, maintaining normal physiological activities, and the like. The injury mechanism of acetabular fracture is mainly high-energy violence acting on the joint surface of acetabulum through the femoral head, which causes bone block displacement and hip joint instability. Accurate fracture typing diagnosis and proper surgical selection are the precondition for good prognosis of patients with acetabular fractures. However, due to the irregular anatomical structure of the acetabulum, the existing Letournel-Juset acetabular fracture typing has certain disadvantages, and making accurate typing diagnosis and selection of reasonable surgical access is a great challenge for most orthopedics. The third hospital Hou Zhiyong teaching team of Hebei university of medical science provides three-column parting theory of acetabulum fracture according to anatomical composition characteristics of acetabulum, and generalizes the operation approach of various fractures in the parting system, thereby providing reference for diagnosis and treatment of acetabulum fracture.
With age, the ilium, pubis and ischial "Y" cartilage interface gradually ossifies to form the acetabulum. Hou Zhiyong teaches that the parts of ilium, pubis, ischium that make up the acetabulum are defined according to their anatomical features as the parietal column 1', anterior column 2', posterior column 3', respectively (see fig. 1, where 4' is the support column); the junction between the anterior column, posterior column, anterior and posterior column are defined as anterior, posterior, and interior walls, respectively, and the acetabular bearing roof region is defined as the top wall.
The team classifies acetabular fractures into single-column fractures, two-column fractures, and three-column fractures according to the number of column/wall separations from the main bone. Single-column fractures are classified into anterior column/wall fractures, posterior column/wall fractures, and parietal column/wall fractures; the two-column fracture is divided into top front column fracture and front and back column fracture; three-column fractures are classified into simple three-column fractures, three-column combined posterior wall fractures, and complex three-column fractures. Among them, fig. 2 is a schematic diagram of a top column/wall fracture in a single column fracture (in total, G, H, I modes), which belongs to a small-size fracture block at the edge of acetabulum in a top column region, and can be said to be a special rear column fracture, and for the special single column fracture, the effect of the existing acetabular fracture bone fracture plate in terms of fracture reduction and internal fixation is still not ideal, and needs to be improved.
