Application of 3D printing technology in endophytic reninoma: A case report and literature review

AbstractObjectivesThe use of three-dimensional (3D) printing in surgery is expanding and there is a focus on comprehensively evaluating the clinical impact of this technology. However, although additional costs are one of the main limitations to its use, little is known about its economic impact. The purpose of this systematic review is to identify the costs associated with its use and highlight the first quantitative data available.MethodsA systematic literature review was conducted in the PubMed and Embase databases and in the National Health Service Economic Evaluation Database (NHS EED) at the University of York. Studies that reported an assessment of the costs associated with the use of 3D printing for surgical application and published between 2009 and 2019, in English or French, were included.ResultsNine studies were included in our review. Nine types of costs were identified, the three main ones being printing material costs (n = 6), staff costs (n = 3), and operating room costs (n = 3). The printing cost ranged from less than U.S. dollars (USD) 1 to USD 146 (in USD 2019 values) depending on the criteria used to calculate this cost. Three studies evaluated the potential savings generated by the use of 3D printing technology in surgery, based on operating time reduction.ConclusionThis literature review highlights the lack of reliable economic data on 3D printing technology. Nevertheless, this review makes it possible to identify expenditures or items that should be considered in order to carry out more robust studies.

Chevron Osteotomy

Abstract Background Cubitus varus deformity (CVD), a common complication after a supracondylar fracture of the distal humerus, is usually treated with corrective osteotomy. However, due to the complex anatomy of the distal humerus, conventional osteotomy techniques are sometimes unreliable and can result in an inaccurate correction, residual deformity, and lateral condyle prominence. Recently, medial three-dimensional (3D) printing technology has demonstrated potential benefits for the treatment of CVD by improving the accuracy of the osteotomy through the use of an osteotomy guide with or without a patient-mated plate. This study aimed to present an interesting CVD case involving a patient who was treated with corrective biplanar Chevron osteotomy using an innovative customized osteotomy guide and a newly designed patient-matched monoblock crosslink plate created with 3D printing technology. Methods A computer simulation was processed using images from computerized tomography(CT) scans of both upper extremities. The biplanar Chevron osteotomy was designed to create identical anatomy between the mirror image of the contralateral distal humerus and the osteotomized distal humerus. Next, the customized osteotomy guide and patient-matched monoblock crosslink plate were designed and printed. A simulation osteotomy for the real-sized bone model was created. Results The operation was performed using the posterior paratricipital approach and the k-wire position from the customized osteotomy guide as a predrilled hole for screw fixation to achieve immediate control of the reduction after osteotomy. Our method helped successfully treat the CVD in the case study patient and significantly improved her radiographic and clinical outcomes with a satisfactory result. Conclusion This study showed that the treatment of CVD using 3D printing technology to create an innovative customized osteotomy guide and a patient-matched monoblock crosslink plate can help accurately assess and control the CVD correction. To the best of our knowledge, this case report introduces a new insight for the clinical application of 3D printing technology in the treatment of CVD.
