, 3D printing has mainly been utilized in pre-operative planning and 3D patient-specific instrumentation (PSI). One of the key focuses in paediatric orthopaedic practice is corrective limb deformity. With increasing accessibility to 3D printing, this

Computer-assisted orthopaedic surgery was born in the 1990s. Nowadays, computer-assisted orthopaedic surgery is used for transpedicular screw fixation and for total knee arthroplasty.
Patient-specific instrumentation is one type of computer-assisted surgery based on volumetric images, such as computed tomography or magnetic resonance imaging.
In this article, possible applications of patient-specific instruments in paediatric orthopaedics are described. The use of patient-specific instrumentation for the correction of cubitus varus is given as an example with complex osteotomy. Another application for tarsal coalition resection is shown.
A last example of using patient-specific instrumentation for both tumour resection and allograft reconstruction is illustrated.
Patient-specific instruments based on computed tomography of the bone can increase peri-operative accuracy and decrease operative time. They are very helpful for the surgeon. Other applications are possible and will be probably developed in the future.
