Abstract

The invention discloses a semi-self-locking acetabulum posterior wall and posterior column anatomical plate which comprises a steel plate main body, a self-locking sleeve and self-locking screws, wherein the steel plate main body is sequentially provided with a first fixing region, a first location region, a main fixing region, a second location region and a second fixing region, the main fixing region is provided with self-locking screw holes, the first fixing region and the second fixing region are provided with non-self-locking screw holes, and the first location region and the second location region are provided with location holes. The invention can be properly twisted and bended and is in convenient moulding so as to be better jointed to a skeleton to bear joint motion load, enable the fracture to be normally healed and reduce complications such as loosening, displacement, pains, bone stress shielding and the like at a later stage of fracture. The invention has the advantages ofhaving less internal stress and relatively according with acetabulum anatomy and biomechanics, enhances the success rate of a fracture internal fixation operation, avoids moulding in the operation, saves the operation time, reduces the blood loss in the operation, reduces the anesthetic time and lowers the operation risks.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a semi-self-locking acetabular posterior wall and posterior column anatomical steel plate used in orthopedic internal fixation operations. Background technique

[0002] With the development of our society, traffic accidents, construction industry and industrial injuries caused by high-energy severe acetabular fractures are increasing day by day, while traditional conservative treatment has a disability rate as high as 50% to 60%, and patients have many complications left behind, such as low back pain , hip arthritis joint pain, gluteal sacral pain, abnormal gait, neurological sequelae, and even loss of working ability. If these diseases are not handled properly, it will not only prolong the patient's treatment time, but also bring mental trauma and economic loss to the patient, seriously affect the quality of life and work of the patient, and even cause disastrous consequ...
