Internal fixation therapeutic method of tibial fracture

Abstract

The invention discloses an internal fixation therapeutic method of tibial fracture, which comprises the following steps: step one, scanning limb skeletons at a healthy side and a fractural side by a spiral CT (Computed Tomography) respectively; step two, reconstructing and outputting a three-dimensional image of the healthy side limb skeletons and a three-dimensional image of the fractural end skeletons by using MIMICS software; step three, respectively measuring and combining the three-dimensional images of the skeletons at the two sides so as to draw a steel plate drawing required for operation; step four, leading the drawing into PRO / E software of a numerical control centre, and customizing completely individualized internal fixation steel plates, bolt holes and positioning templates after serial technological processes; and step five, implanting the individualized internal fixation steel plates and bolt holes into the fractural skeletons through a minimally invasive surgery by using the positioning templates produced in the step four, thereby finishing the internal fixation operation. The internal fixation therapeutic method has the advantageous effects of capably shortening operative time, capably minimizing periosteal injury around the fractural end, having small operative incision in appearance and enabling fractural patients to heal quickly.

Description

technical field [0001] The invention relates to an internal fixation treatment method for tibial fractures. Background technique [0002] The concept of internal fixation of traumatic orthopedic fractures has developed from the concept of AO (Arbeit Fuer Osteosynthese; Association for the study of internal fixation) to the current popular BO (Biological Osteosynthesis, biological fixation). In recent years, some people have proposed CO ( Chinese Osteosynthesis, combined traditional Chinese and Western medicine osteosynthesis) concept. The principle remains the same, what modern minimally invasive orthopedics advocates is: in order to make fracture patients less iatrogenic injury, faster healing and fewer complications. However, the implanted instruments for internal fixation of fractures currently used in clinical practice, such as interlocking intramedullary nails, anatomical plates, limited contact compression plates, locking compression plates, etc., are not completely i...

AI Technical Summary

Problems solved by technology

However, the implanted devices for internal fixation of fractures currently used in clinical practice, such as interlocking intramedullary nails, anatomical plates, limited contact compression plates, locking compression plates, etc., are not completely individualized.

Due to individual differences and ever-changing fracture conditions, the implant cannot fully match the bone anatomy of the affected limb, resulting in delayed fracture healing in some patients, even nonunion, malunion, fracture of the internal implant, difficulty in taking it out, etc.
