Child DDH acetabular osteotomy orthopedic guide plate and use method thereof

Abstract

The invention provides a child developmental dysplasia of a hip (DDH) acetabular osteotomy orthopedic guide plate and a use method thereof. The guide plate includes an osteotomy guide plate and a downward-pressure spreading guide plate, the osteotomy guide plate has a shape that fits with a joint capsule at the outer upper part of an acetabulum and surrounding bone surfaces, and the osteotomy guide plate has a preset height of an osteotomy groove and a plurality of Kirschner pinholes; and the downward-pressure spreading guide plate is provided with two side plates and a connecting part, the two side plates are respectively arranged on two sides of the downward-pressure spreading guide plate, a tip opening shape is formed between the two side plates, the bottoms of the two side plates are connected through the connecting part, and the connecting part is connected by a bar. The orthopedic osteotomy plate system for completing osteotomy operation during orthopedic surgery and integratingpositioning, guiding and ranging and the operation method are provided in the invention, the safety and accuracy of the surgery can be improved, the surgery time can be shortened, and excessive X-rayradiation can be avoided.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a 3D printed guide plate device for precise osteotomy of the acetabulum with developmental dysplasia of the hip in children. Background technique [0002] Developmental dysplasia of the hip (DDH) is a disorder of the hip joint that appears in infancy or childhood, with an incidence of about one in a thousand surviving newborns. Many reports indicate that DDH osteotomy is complicated to operate and has a long learning curve. The success of the operation is closely related to the reasonable choice of the operation method and the experience of the surgeon, which is prone to errors in deformity assessment. [0003] Among the various pelvic osteotomies for DDH, the modified Pemberton and Dega acetabular pericapsular osteotomies are most frequently used. However, regardless of the operation method, the surgeon needs to cut the osteotomy by hand with his experience. The disadva...

Problems solved by technology

However, regardless of the operation method, the surgeon needs to cut the osteotomy by hand with experience. The disadvantage of this is that the osteotomy is used for complex orthopedic surgery, which has large errors, inconvenient operation and low efficiency.
