A preparation method of personalized bone plate for complex pelvic acetabular fractures

Abstract

The invention discloses a method for preparing a personalized bone plate for complex pelvic acetabular fractures, which comprises the following steps: based on the CT scan data of the patient's medical image in DICOM format, importing it into the medical image software Minics to establish the patient's pelvic bone Model; Wherein, the data of patient's unbroken pelvis side is preserved as the data of STL format, export; The data of STL format is imported in the Geomagic Studio software and processed, save as the file of STP format, export; Export the Import the STP file data into SolidWorks, extract the bone surface, carry out reverse design, and design a personalized bone plate model suitable for different individuals with complex pelvic and acetabular fractures. According to the broken pelvis of different people, the present invention designs individual bone plates with high compatibility; at the same time, 3D printing technology can process parts with complex structures, and the processing cycle is short, which is very suitable for small batches of personalized customization.

Description

technical field [0001] The invention relates to medical bone-synthetic components, in particular to a method for preparing a personalized bone-synthetic plate for complex pelvic acetabular fractures. Background technique [0002] The incidence of pelvic and acetabular fractures is relatively low—less than 2% of the total number of orthopedic trauma cases, mostly caused by high-speed traffic injuries, and acetabular fractures caused by other injuries such as falling injuries and sports are relatively rare. However, pelvic and acetabular fractures often damage other organs, blood vessels and nerves, and severely damage the anatomical structure of the hip joint. Therefore, acetabular fractures have relatively high mortality and disability rates. Deep, irregular bone structure, numerous peripheral blood vessels and nerves, and various types of fractures, large surgical trauma, difficult reduction and fixation. In addition, using the lateral rectus abdominus approach can fully e...

However, pelvic and acetabular fractures often damage other organs, blood vessels and nerves, and severely damage the anatomical structure of the hip joint. Therefore, acetabular fractures have relatively high mortality and disability rates. Deep, irregular bone structure, numerous peripheral blood vessels and nerves, and various types of fractures, large surgical trauma, difficult reduction and fixation

In addition, using the lateral rectus abdominus approach can fully expose the fracture site through a small incision and reduce surgical trauma, but the matching of ordinary bone plates is poor, and a large number of standard bone plates is required for one operation, which cannot realize individualized treatment, which has become a limitation of the pelvic hip joint. The biggest obstacle to the minimally invasive treatment of acetabular fractures, so there is an urgent need for individualized bone plates to meet clinical needs
