“…Parts destined for high-stress applications should be fully dense, to minimize the possibility of part failure during service. degrees of porosity is sometimes desirable and with respect to the fact that both investigated alloys are mostly dedicated to the dental application [20], it can be intentionally engineered into certain bio-medical implants since the pores promote better osseo integration with biological tissue [24]. the quantitative image analysis show different porosity behaviour in both investigated alloys.…”

The main aim of the present paper is to evaluate the porosity and mechanical properties of Ti6Al4v and CoCrW alloys produced by Laser Powder Bed Fusion (L-PBF) as an additive manufacturing (AM) technology. Ti6Al4v and CoCrW alloys are attractive for medical application. the complex examination of porosity for these alloys needs the quantification of morphological and dimensional characteristics. Quantification of porosity was realized on non-etched samples. Quantitative image analysis was used to describe the dimensional and morphological porosity characteristics. the pores were evaluated by image pro plus software. the results show the significant inhomogeneity of the morphology and distribution, as well as the pore size in the investigated materials and underline the importance of pore structure for the controlling mechanism of the mechanical response.

When a limb suffers a fracture, rupture, or dislocation, it is traditionally immobilized with plaster. This may induce discomfort in the patient, as well as excessive itching and sweating, which creates the growth of bacteria, leading to an unhygienic environment and difficulty in keeping the injury clean during treatment. Furthermore, if the plaster remains for a long period, it may cause lesions in the joints and ligaments. To overcome all of these disadvantages, orthoses have emerged as important medical devices to help patients in rehabilitation, as well as for self-care of deficiencies in clinics and daily life. Traditionally, these devices are produced manually, which is a time-consuming and error-prone method. From another point of view, it is possible to use imageology (X-ray or computed tomography) to scan the human body; a process that may help orthoses manufacturing but which induces radiation to the patient. To overcome this great disadvantage, several types of 3D scanners, without any kind of radiation, have emerged. This article describes the use of various types of scanners capable of digitizing the human body to produce custom orthoses. Studies have shown that photogrammetry is the most used and most suitable 3D scanner for the acquisition of the human body in 3D. With this evolution of technology, it is possible to decrease the scanning time and it will be possible to introduce this technology into clinical environment.

Illustration by the authors with Artec Studio 13 software program Version 13, Artec Group, Luxembourg resolution of 0,1 mm the portable Artec Eva 3D-Scanner offers these advantages, and has shown significant correlation to the water displacement method with an identified mean error of only 1.4% in previous studies [9,10,[24][25][26][27]. Due to high resolution and three-dimensional representation, swelling conditions of the lower extremities can be assessed even in the case of concomitant open wounds.…”

Background Soft tissue swelling assessment benefits from a reproducible and easy to use measurement method. Monitoring of the injured lower extremity is of clinical import during staged soft tissue management. Portable 3D scanners offer a novel and precise option to quantify and contrast the shapes and volumes of the injured and contralateral uninjured limbs. This study determined three regions of interest (ROI) within the lower extremity (lower leg, ankle and foot), that can be used to evaluate 3D volumetric assessment for staged soft tissue management in orthopedic and trauma surgery. Methods Twelve healthy volunteers (24 legs) were included in this cohort study. Scans of all three ROI were recorded with a portable 3D scanner (Artec, 3D scanner EVA) and compared between the right and left leg using the software Artec Studio (Arctec Group, Luxemburg). Results Mean volume of the right leg was 1926.64 ± 308.84 ml (mean ± SD). ROI: lower leg: 931.86 ± 236.15 ml; ankle: 201.56 ± 27.88 ml; foot: 793.21 ± 112.28 ml. Mean volume of the left leg was 1937.73 ± 329.51 ml. ROI: lower leg: 933.59 ± 251.12 ml; ankle: 201.53 ± 25.54 ml; foot: 802.62 ± 124.83 ml. There was no significant difference of the overall volume between right and left leg (p > 0.05; overall volume: △ difference: 29.5 ± 7.29 ml, p = 0.8; lower leg: △ difference: 21.5 ± 6.39 ml, p = 0.8; ankle: △ difference: 5.3 ± 2.11 ml, p = 0.4; △ difference: 16.33 ± 4.45 ml, p = 0.8. Conclusion This pilot study defines three regions of interest of the lower leg and demonstrates no difference between the right and left side. Based on these ROI, further studies are needed to evaluate the clinical applicability of the scanner.
