Abstract
In the ﬁeld of pediatric orthopaedics, deformity correction of limb is important procedure. In general,bony deformity is three-dimensional (3D) and detailed preoperative planning is important for precise
correction of limb deformity. Recently, computed tomography (CT)-based 3D modeling can be easily
performed using computer software and this technique is used for preoperative planning. The advancesin computer assistance technology have allowed detailed 3D preoperative planning and simulationof preoperative plans. And the use of a computer navigation system as an intraoperative assistancetool allows more accurate execution of the preoperative plan compared to manual operation without
assistance of the navigation system.
Corrective osteotomy is performed as a surgical treatment for several pediatric disorders; however,this procedure requires advanced surgical techniques. In hip osteotomy using a CT-based navigation,
the navigation allows 3D preoperative planning, intraoperative confirmation of osteotomy sites, safe
performance of osteotomy even under poor visual conditions, and a reduction in exposure doses fromintraoperative ﬂuoroscopy. For small patients in whom a CT-based navigation cannot be used, a 3D bonemodel and patientsspeciﬁc guide by segmenting patient's CT data using 3D slicer software are useful for
precise execution of preoperative planning.
Although computer assistance technology is useful for corrective osteotomy, this technology is still in thedevelopment stage and has not been adopted widely. We have been using computer assistance technology
to prepare 3D preoperative plans for hip osteotomy, both pelvic and femoral osteotomies. In addition,in order to execute the preoperative plans, we use a CT-based computer-assisted navigation. And wehave also used a 3D bone model and patients-speciﬁc guide for patients who cannot undergo CT-basednavigated surgery.
In this presentation, we describe the status of corrective osteotomy with the use of computer-assisted
navigation, which we perform at our department, and discuss the future prospects of these techniques.
