“…Carfagni et al (2019) fabricated the surgical guides for correction of the PA using FDM technology in ULTEM 1010 material, a biocompatible resin (ISO 10993/USP Class VI) that offers excellent strength and thermal stability such that it can be sterilized by steam autoclaving (a technique commonly used in hospitals) without undergoing deformation. On the other hand, for the fabrication of templates to bend corrective thoracic bars in a controlled and planned manner, the requirement for biocompatibility and sterilizability of materials is not mandatory, so several studies used PLA material for template fabrication (Lin et al, 2018;Huang et al, 2019;Bellia-Munzon et al, 2020;Gaspar Pérez et al, 2021). Finally in Bugajski et al (2019), for the realization of a pressure sensor housing to be integrated in a compression bar, the authors evaluated that the yield strength of the material was sufficient to withstand the compression and bending loads to which the bar is subjected, choosing for this purpose ABS as a compatible material.…”

“…The (more or less) invasive surgical procedures for the correction of PE involve the insertion of a metal bar that, as mentioned in section “Current clinical approaches”, is manually shaped by the surgeon in surgical room, at the expense of a difficult prediction of the final shape of the thorax. In order to improve the aesthetic results, in (Lin et al , 2018; Huang et al , 2019; Bellia-Munzon et al , 2020; Gaspar Pérez et al , 2021) was proposed CAD modelling and fabrication with AM techniques of a customized plastic bar template to guide the surgeon in manually shaping the metal bar. Vilaça et al (2014) proposed a method to custom-bend the bar by analyzing CT of the chest through a system called i3DExcavatum.…”

Purpose Among thoracic malformations, pectus deformities have the highest incidence and can result in a wide range of severe and mild clinical manifestations. Recently, the treatment of pectus deformities is shifting from traditional approaches toward customized solutions. This occurs by leveraging innovative rapid prototyping tools that allow for the design and fabrication of patient-specific treatments and medical devices. This paper aims to provide a comprehensive view of the growing literature in this area to analyze the progress made in this direction. Design/methodology/approach The search was performed on major search engines through keywords inherent to reverse engineering (RE) and additive manufacturing (AM) technologies applied to pectus deformities and related treatments, selecting 54 papers. These were analyzed according to the addressed pathology, the hardware and software tools used and/or implemented and their integration within the clinical pathway. Findings First, the analysis led to analyze and divide the papers according to how RE and AM technologies are applied for surgical and non-surgical treatments, pathological assessment and preoperative simulation and planning. Second, all papers were considered within the typical rapid prototyping framework consisting of the three phases of three-dimensional (3D) scanning, 3D modelling and 3D printing. Originality/value To the best of the authors’ knowledge, to date, no survey has provided a comprehensive view of innovative and personalized treatment strategies for thoracic malformations; the present work fills this gap, allowing researchers in this field to have access to the most promising findings on the treatment and evaluation of pathology.

“…Optimal prints with anatomic match were created in 92.3% ( n = 120); implant rebending was only needed in 5.4% of the patients. They too found a decrease in operation time (87.6 ± 49.9 min compared to 125.4 ± 30.7 min, p < 0.0001) as well as fewer bars used (2.6 ± 0.5 versus 1.7 ± 0.6, p < 0.001) [ 34 ].…”

Medicine is a rapidly-evolving discipline, with progress picking up pace with each passing decade. This constant evolution results in the introduction of new tools and methods, which in turn occasionally leads to paradigm shifts across the affected medical fields. The following review attempts to showcase how 3D printing has begun to reshape and improve processes across various medical specialties and where it has the potential to make a significant impact. The current state-of-the-art, as well as real-life clinical applications of 3D printing, are reflected in the perspectives of specialists practicing in the selected disciplines, with a focus on pre-procedural planning, simulation (rehearsal) of non-routine procedures, and on medical education and training. A review of the latest multidisciplinary literature on the subject offers a general summary of the advances enabled by 3D printing. Numerous advantages and applications were found, such as gaining better insight into patient-specific anatomy, better pre-operative planning, mock simulated surgeries, simulation-based training and education, development of surgical guides and other tools, patient-specific implants, bioprinted organs or structures, and counseling of patients. It was evident that pre-procedural planning and rehearsing of unusual or difficult procedures and training of medical professionals in these procedures are extremely useful and transformative.

“…Each implant has its own features, and one type may only fit a specific chest wall defect. Some need to be designed and prepared beforehand, and some are very expensive (4)(5)(6)(7)(8). Out of all the reports of chest wall reconstruction, there is no satisfactory, readily available, affordable material and method intended for various defects.…”

Background: Chest wall disease is a common disease in thoracic surgery. For most chest wall lesions, surgical resection is the mainstay of treatment. Reconstruction is indicated for a wide range of chest wall defects. Currently, various reconstruction materials are used in clinic, including 3D printing materials and various types of metal materials. At present, most of the studies using titanium sternum-rib fixation system for reconstruction are case reports. The purpose of this paper is to analyze the experience to discuss our essential surgical techniques for treating various types of chest wall reconstruction with a titanium sternumrib fixation system over the last 5 years.Case Description: A retrospective analysis was performed on patients with chest wall tumors treated with a titanium sternum-rib fixation system in our center from 2016 to 2020. Chest wall reconstruction techniques, experiences, postoperative complications, and quality of life including chest discomfort, chronic pain, average time to return to normal life, chest wall deformity after resection for various types of chest wall tumors were analyzed. In this study, a total of 57 patients were successfully operated without chest wall deformity and return to daily life early. With an average of 2.3 ribs removed, including 10 procedures involving sternotomy and reconstruction and 3 procedures involving sternoclavicular joint resection and reconstruction. The follow-up time of the whole group ranged from 3 months to 5 years. Postoperative chest discomfort occurred in 6 patients during follow-up; 2 patients had chronic pain. The average time to return to normal life was 1.4 months. One patient developed a deformed depression of the chest wall, and 2 patients developed wound infections. There was no perioperative death.Conclusions: In our clinical experience, the titanium sternum-rib fixation system is safe, effective, and feasible. The technique is straightforward. The early and middle postoperative curative effect is satisfactory and can be used clinically.
