Conditions
Brief summary
Paediatric bone deformities can result from congenital conditions or acute injuries and often require orthopaedic intervention. For example, a femoral de-rotation osteotomy may be performed to address the in-toeing gait observed in a child with cerebral palsy, or this procedure may be performed to correct the out-toeing gait pattern caused by a slipped capital femoral epiphysis fracture. These orthopaedic procedures are highly complex and involve multi-plane correction requiring a high level of surgical expertise and experience. In this project, we will: - Develop tools to rapidly produce personalised computational models of paediatric patients with bone deformities, - Develop technology to perform virtual surgical simulations to optimize surgical pre-planning, - Develop technology to simulate post-operative walking function, - Design and manufacture surgical cutting guides using 3D printing, - Utilize 3D printed surgical guides in surgery to streamline the translation of the virtual plan to surgical execution, - Evaluate surgical outcomes and accuracy of pre-operative surgical predictions of post-operative function. The primary aim of the proposed research is to determine the efficacy of virtual surgery and personalised cutting guides for the surgical treatment for children with bone deformity in Queensland. We expect the inclusion of virtual surgery and 3D printing of surgical guides will result in improved anatomical alignment and improved post operative walking kinematics.
Interventions
Intervention: Virtual surgery will be simulated to determine an optimal orthopaedic correction for patient’s waitlisted for proximal femoral bone deformity correction. Following virtual planning, which is estimated to take one week per patient (computational time and researcher time), personalised cutting guides will be designed, 3D printed and used in surgery to facilitate translation of the virtual plan to surgical execution. The surgical intervention is personalised and will be delivered on a
Intervention: Virtual surgery will be simulated to determine an optimal orthopaedic correction for patient’s waitlisted for proximal femoral bone deformity correction. Following virtual planning, which is estimated to take one week per patient (computational time and researcher time), personalised cutting guides will be designed, 3D printed and used in surgery to facilitate translation of the virtual plan to surgical execution. The surgical intervention is personalised and will be delivered on a single occasion. Face to face pre-operative motion capture and medical imaging assessment’s will be conducted within 6 months prior to surgery and post-operative motion capture and medical imaging assessment’s will be conducted 9-12 months post-surgery. Data management will be undertaken using REDCap and data fidelity will be supervised by Dr Carty, who has extensive experience in projects involving medical imaging and motion capture data. Technology and experience: Virtual surgery will be informed by a fusion of motion capture data and medical imaging. Motion capture data will be collected and analysed by a biomechanist, and medical imaging data will be collected by a radiographer and viewed by a radiologist for incidental findings. Image fusion, virtual surgery and manufacture of cutting guides will be conducted by a team of biomedical and mechanical engineers in partnership with orthopaedic surgeons. Surgical execution will be conducted by an orthopaedic surgeon with extensive experience in paediatric lower limb deformities.
