“…Zhang et al [33] obtained satisfactory results using a CAD navigation template on cubitus varus deformity, but this template only corrected the varus deformity. Omori et al [16] designed a surgical navigation template to correct the 3D deformity, but its large size made the surgical incision larger than that of conventional surgery, which was not easily accepted by patients.…”

“…Treatment for cubitus varus deformity is now trending toward 3D correction [14], but this technique is challenging for orthopedic surgeons [15][16][17][18]. Accurately controlling the correction angle of each dimension during the operation is difficult, and the degree of correction must often be repeatedly adjusted during surgery or determined based on general appearance.…”

Background: Cubitus varus deformity is a common sequela of elbow fractures in children. Cubitus varus deformity treatment is tending toward 3D correction, which is challenging for orthopedic surgeons. This study aims to explore whether individualized 3D-printed navigation templates can assist with accurate and effective corrective treatment of children with cubitus varus deformity. Methods: Thirty-five patients were treated for cubitus varus deformity from June 2015 to April 2017, including 21 boys and 14 girls, aged 4.6-13.2 years (average, 7.5 years). Of these cases, 17 deformities were on the left side and 18 were on the right side. All were treated with wedge osteotomy of the lateral distal humerus. 3D-printed navigation templates were used in 16 cases, while traditional surgery was used in 19 cases. All patients underwent computed tomography scans before surgery. Computer software was used to analyze the measurements and design and print individualized navigation templates. The navigation templates were matched, and surgery was initially simulated. Intraoperative individualized navigation templates were used to assist with accurate osteotomy and Kirschner wire fixation. Operation times were recorded in all cases, the carrying angles before and after surgery were assessed by computer, and postoperative elbow joint function was evaluated using Bellemore criteria. All measurement data were presented as means ± SD, and Student's t test was used to examine differences between groups. All count data between both groups were compared using the chi-square test or Fisher's exact test analysis. Results: All individualized navigation templates matched well with the corresponding anatomical markers and were consistent with preoperative planning, simulated surgery, and intraoperative procedures. Average operation times from clear exposure to fixed Kirschner wire were 11.69 min (9.6-13.5 min) for the individualized navigation template group and 22.89 min (17.7-26.8 min) for the traditional operation group (p < 0.001). Average differences in postoperation carrying angles between affected and healthy sides were 1.13°(0-2.0°) and 4.21°(0-7.5°), respectively (p < 0.001). Follow-up 6-12 months postoperation showed that elbow function did not differ significantly between groups using the Bellemore criteria (p > 0.05). Conclusions: Individualized navigation templates simplify procedures, reduce operation time, and improve accuracy when used in orthopedic surgery to treat children with cubitus varus deformity.

“…Studies have described the use of the guide as a promising technique. They have demonstrated good clinical outcomes [19–25] and high accuracy [26–28] in performing corrective osteotomies for upper limb deformities, and have reported its utility for the intra-articular correction of the distal radius [29, 30]. The 1.0-mm expansion of the physeal bar was defined as a target knowing that approximately 0.5 mm is the mean error in creating the models [14], and the diameter of the K-wires mentioned later is 0.5 mm.…”

The partial physeal arrest of the distal radius could result in progressive deformities and functional problems of the wrist. Despite being the most preferred surgical intervention, physeal bar resection (Langenskiöld procedure) is technically demanding. This manuscript aims to illustrate the technical tricks and present an illustrative case of premature physeal arrest of the distal radius managed with a novel method for the Langenskiöld procedure, involving complete removal of the bar using a patient-specific guide in combination with an intramedullary endoscopy technique that facilitated direct observation.

“…The technology has made great headway in designing patient-specific instruments. Once the planning and simulation are done at the backend office, appropriate jigs and cutting tools can be made using rapid prototyping [7,[12][13][14]. Several companies are aggressively developing this technology; and several proprietary devices such as Signature by Biomet and Visionaire by Smith & Nephew are currently available internationally ( Fig.…”

Planning is a key step in all surgeries. Well-planned cases have better outcomes than the unplanned ones. The conventional planning used to be done on radiographs and other imaging. Three-dimensional D printing using additive manufacturing process has taken this a step further. The process involves converting the radiographic digital formats into machine-printable format. The three-dimensional model is typically made of a plastic material that allows surgical simulation.In complex arthroplasty, especially those such as revision scenarios or difficult primary cases such as dysplastic hips, protrusio, fused, or posttraumatic arthritic hips, these models serve as an invaluable tool in planning the surgery. They help reduce inventory by facilitating optimal implant and instrument ordering, and also serve as intraoperative referencing. "y performing surgical simulations preoperatively, the surgeons can rehearse their surgical steps and also decide upon the implant type and accurate implant placements.
