Introduction and Objective. Virtual Surgical Planning (VSP) is becoming an increasingly important means of improving skills acquisition, optimizing clinical outcomes, and promoting patient safety in orthopedics and traumatology. Pediatric Orthopedics (PO) often deals with the surgical treatment of congenital or acquired limbs and spine deformities during infancy. The objective is to restore function, improve aesthetics, and ensure proper residual growth of limbs and spine, using osteotomies, bone grafts, age-specific or custom-made hardware and implants. Materials and Methods. Three-dimensional (3D) digital models were generated from Computed Tomography (CT) scans, using free open-source software, and the surgery was planned and simulated starting from the 3D digital model. 3D printed sterilizable models were fabricated using a low-cost 3D printer, and animations of the operation were generated with the aim to accurately explain the operation to parents. All procedures were successfully planned using our VSP method and the 3D printed models were used during the operation, improving the understanding of the severely abnormal bony anatomy. Results. The surgery was precisely reproduced according to VSP and the deformities were successfully corrected in eight cases (3 genu varum in Blount disease, 2 coxa vara in pseudo achondroplasia, 1 SCFE, 1 missed Monteggia lesion and 1 post-traumatic forearm malunion deformity). In one case, a focal fibrocartilaginous dysplasia, the intraoperative intentional undersizing of the bone osteotomy produced an incomplete correction of a congenital forearm deformity. Conclusions. Our study describes the application of a safe, effective, user-friendly, VSP process in PO surgery. We are convinced that our study will stimulate the widespread adoption of this technological innovation in routine clinical practice for the treatment of rare congenital and post-traumatic limb deformities during childhood

Aims & Background. Congenital Talipes Equinovarus (CTEV) is the most common congenital musculoskeletal birth defect affecting 1 in 1000 births per annum. We have compared our surgical results to the British Society of Children's Orthopaedics (BSCOS) published guidelines. Methods. Between, 2006–16, patients who were referred for treatment of pathological CTEV were audited. Data from a combination of Clinical Portal, Orthotic Patient Administration System and Surgical Elogbook were assessed. In addition, the degree of deformity was classified by the Harrold & Walker method at the time of diagnosis (senior author). Most of this information was recorded prospectively and analysed retrospectively. Ponseti technique was the method of treatment. Results. 96 patients assessed (133 feet). There were 78 males and 18 females, 37 patients were affected bilaterally and 11 had associated syndromes. There were 23 Harrold & Walker (H&W) 1, 28 H&W 2 and 82 H&W 3 classification feet. Average time period in Ponseti boots and bars was 14.4 months (95% CI 12.9–15.9), average time in all types of bracing of was 17.1 months (95% CI 14.8–14.8). Number and rate of surgeries performed were as follows: 77 Tendoachilles release (63.1%), 19 Tibialis Anterior Transfer (5.6%), 15 Radical Release (12.3%), revision 25 Surgery (20.5%) & 5 Abductor Hallucis Release (4.1%). Conclusion. The audit confirms that the unit meets most of the current BSCOS guidelines. All surgical procedures apart from radical release surgery fall within accepted limits. This may be due, in part, to the syndromal cases. We do however demonstrate a significantly reduced average time period in bracing compared to that recommended by BSCOS. There are multiple reasons for this discrepancy including non-compliance and poor splint tolerance (child refusing to use). We feel this work demonstrates a reduced period in bracing can be achieved whilst maintaining standards of treatment
