“…Новые технологии ВВЕДЕНИЕ За последнее десятилетие технология трехмерной печати получила развитие в медицине, она открывает новые перспективы в научных исследованиях, обучении персонала и в индивидуальном подходе к лечению, позволяя повысить его эффективность [1][2][3]. По мнению специалистов, в хирургии трехмерную печать можно использовать для создания геометрически сложных и высокодетализированных персонализированных конструкций и их одноразового изготовления, для предоперационного планирования, проектирования ортопедических изделий и протезирования в соответствии с конкретными требованиями хирурга и пациента [3][4][5][6], для создания вспомогательных средств, адаптированных для конкретного пациента, для интраоперационного использования, создания аппаратных средств и индивидуальных устройств, протезов для имплантации, быстрого создания прототипов хирургически имплантируемых изделий, а также приложений для обучения стажеров [7][8][9][10]. Преимуществом технологии является то, что индивидуальные имплантаты и слепки могут быть изготовлены в соответствии с анатомией конкретного человека [9,11].…”

Introduction The use of 3D printing technology in finger reconstruction improves accuracy of the procedure minimizing the donor defect and optimizing the appearance and function of the finger. The use of this technology in the finger reconstruction with an osteocutaneous radial forearm flap with axial blood supply and lengthening of the digital stumps and metacarpals remains poorly explored.The objective of the study was to demonstrate new methods of preoperative planning for finger reconstruction and improve surgical outcomes.Material and methods Outcomes of five patients treated with original methods based on 3D technology were retrospectively evaluated during preoperative planning, reconstruction of the thumb using an osteocutaneous radial forearm flap with axial blood supply, relocation of the stump of the third finger and lengthening of the stumps of the first and second metacarpals. The patients could achieve consolidation of interpositional bone allografts following lengthening of the finger stumps, stability of the bone base of the finger, organotypic restructuring of the marginal allograft during plastic surgery with an osteocutaneous radial forearm flap, and a functional position of the reconstructed thumb using the middle finger stump.Results and discussion An individual device for planning finger reconstruction allows identification of the optimal size and position of the finger in three planes, which is essential for patients with severe hand deformities to avoid corrective procedures. An individual guide was used to osteotomize the radius to harvest a vascularized graft providing a cutout of a given size and shape and a cortical-cancellous allograft being identical in shape and size to replace the donor bone defect. The combined use of Masquelet technology and distraction of the finger stump or a metacarpal improved conditions for consolidation and restructuring of the interpositional allograft preventing fractures and infection.Conclusion The use of 3D technology in finger reconstruction using an osteocutaneous radial forearm flap with axial blood supply and distraction of the finger stumps and metacarpals can improve surgical outcomes.

“…Nevertheless, studies have shown that surgeons benefit from 3-D technology when dealing with complex cases (Meyer-Szary et al., 2022) and that the use of 3-D models contributes to patient education (Bizzotto et al., 2015; Samaila et al., 2020). There have been continuous efforts to validate applications of this technology as well as its cost effectiveness (Keller et al., 2021; Samaila et al., 2020). Cost effectiveness has been successfully demonstrated in other fields (Chamo et al., 2020); assistance to surgeons, especially with complex cases, should result in shorter operating times and fewer indirect costs.…”

The use of three-dimensional (3-D) technology in upper extremity surgery has the potential to revolutionize the way that hand and upper limb procedures are planned and performed. 3-D technology can assist in the diagnosis and treatment of conditions, allowing virtual preoperative planning and surgical templating. 3-D printing can allow the production of patient-specific jigs, instruments and implants, allowing surgeons to plan and perform complex procedures with greater precision and accuracy. Previously, cost has been a barrier to the use of 3-D technology, which is now falling rapidly. This review article will discuss the current status of 3-D technology and printing, including its applications, ethics and challenges in hand and upper limb surgery. We have provided case examples to outline how clinicians can incorporate 3-D technology in their clinical practice for congenital deformities, management of acute fracture and malunion and arthroplasty.

The conventional treatment for distal radius fractures typically involves immobilization of the injured extremity using a conventional forearm cast. These casts do cause all sorts of discomfort during wear and impose life-style restrictions on the wearer. Personalized 3D printed splints, designed using three-dimensional (3D) imaging systems, might overcome these problems. To obtain a patient specific splint, commercially available 3D camera systems are utilized to capture patient extremities, generating 3D models for splint design. This study investigates the feasibility of utilizing a new camera system (SPENTYS) to capture 3D surface scans of the forearm for the design of 3D printed splints. In a prospective observational cohort study involving 17 healthy participants, we conducted repeated 3D imaging using both the new (SPENTYS) and a reference system (3dMD) to assess intersystem accuracy and repeatability. The intersystem accuracy of the SPENTYS system was determined by comparison of the 3D surface scans with the reference system (3dMD). Comparison of consecutive images acquired per device determined the repeatability. Feasibility was measured with system usability score questionnaires distributed among professionals. The mean absolute difference between the two systems was 0.44 mm (SD:0.25). The mean absolute difference of the repeatability of the reference -and the SPENTYS system was respectively 0.40 mm (SD: 0.30) and 0.53 mm (SD: 0.25). Both repeatability and intersystem differences were within the self-reported 1 mm. The workflow was considered easy and effective, emphasizing the potential of this approach within a workflow to obtain patient specific splint.
