A PATIENT-SPECIFIC ELECTRONIC TEMPLATE FOR USAGE IN CORRECTIVE OSTEOTOMIES FOR TREATING BONE AND JOINT DEFORMITIES

NºPublicación: WO2019052622A1 21/03/2019

Solicitante:

HAFEZ MAHMOUD ALM EL DIN [EG]

Resumen de: WO2019052622A1

This invention relates to patient specific templates for osteotomy is to predetermine the exact direction and degree of deformity before surgery and to estimate postoperative limb alignment which must mimic the physiologic loading to secure favorable clinical outcome. The Correction osteotomy using conventional techniques may lead to under and over correction. We designed a patient specific templating technique for high tibial osteotomy and also for corrective osteotomy of shaft deformities. The technique was applied for unilateral and bilateral high tibial osteotomy and tibial shaft deformity. The patient specific templates are based on CT-scan images which transferred to a specific software to construct a 3D model of bone. A virtual planning of the surgery is done to design the templates which are used to perform the surgery. The 3D printing machine is used to produce the patient specific template.

PATIENT-SPECIFIC TEMPLATES FOR PEDICAL SCREW INSERTION IN CORRECTIVE SCOLIOSIS SURGERIES

NºPublicación: WO2019052623A1 21/03/2019

Solicitante:

HAFEZ MAHMOUD ALM EL DIN [EG]

Resumen de: WO2019052623A1

This invention relates to a surgical device for the detection of the pedicle screws trajectories of a patient undergoing to scoliosis or spondylosis correction. The device is a patient specific and has information about screw size and position. The increased use of pedicle screws in scoliosis creates a challenge for accurate and safe placement of screw within the pedicle during the scoliosis surgery. Patient-specific templates (PST), is an alternative method to guide the surgeons for detecting the positions and trajectories of pedicle screws in scoliosis and spondylosis fixation surgery. This 3D model constructed during PST process can be also 3D printed as a physical model, which can help surgeons to develop an accurate and safe position of pedicle screws and its trajectories. This device has the ability to customize the placement and the size of each pedicle screw based on the unique morphology and landmarks of the vertebrae.
