Description
[technical field]
This utility model relates to the surgical medical equipment technical field, specifically, is a kind of anatomical form acetabular bone rear pillar steel plate.
[background technology]
The pelvis fracture of acetabulum is a kind of severe trauma, how by due to the extruding of direct violence pelvis, is more common in vehicle accident and landslide.Along with the continuous development of Chinese society, injury of pelvis that building industry, vehicle accident and industrial injury cause and serious fracture of acetabulum increase gradually, and the fracture mortality rate of pelvis and acetabular bone is up to 10%, abroad report even higher.Traditional conservative is treated disability rate up to 50%-60%, and has multiple complications, like buttocks sacrum pain, low back pain, abnormal gait, coxitis arthralgia, nerve sequela etc.This not only brings psychic trauma and economic loss to patient, has a strong impact on patient's live and work quality, even causes catastrophic effect; Social medical treatment and financial burden have also been increased simultaneously.Since the eighties in 20th century, along with pelvis and fracture of acetabulum understanding mechanism is deepened continuously, Therapeutic Method develops to operative treatment from the past expectant treatment.Along with open internal fixation continuous advancement in technology, operative treatment pelvis and fracture of acetabulum more and more are widely accepted in recent years.
The acetabular bone that operative treatment is commonly used at present and the configuration of surface of pelvis reconstruction plate and acetabular bone and pelvis are not docile, need carry out moulding according to the different skeletal form characteristics of patient in the art.And, often once be difficult to moulding success because acetabular bone and pelvis surface configuration are complicated, and the need repeated multiple times just can make steel plate and bone surface form docile.This method exists following drawback: the moulding repeatedly and bending of (1) steel plate, and can make steel plate at the bending part stress concentration, the danger of implant fatigue fracture is increased.(2) the moulding process of steel plate has prolonged operating time, and otch open-assembly time and anesthesia duration are prolonged, and blood loss volume during the operation increases with the anesthesia dosage, and operation potential risk and complication are increased.(3) if steel plate will cause loosening, the displacement of fracture moulding bad not docile with skeleton, cause the stress shielding of pain and bone, cause incidence rates such as malunion of fracture or malunion to increase.
Anatomical plate has reduced the moulding repeatedly adverse consequences that causes based on the dissect physiology structural design of skeleton.
