“…Guo [8] applied the 3D printed titanium alloy prosthesis of scapula and clavicle to repair the defects of scapula and clavicle after tumor resection, which achieved good clinical results. Cheng et al used individualized 3D printed titanium alloy prosthesis to repair traumatic defects of distal fibula and lateral malleolus, satisfactory results were also achieved [3] . Although 3D printed titanium alloy prosthesis has incomparable advantages over traditional treatment methods, it still has limitation as that it cannot meet the needs of continuous bone growth for children and adolescent patients who are still in the period of bone development.…”

“…Segmental bone defect of ulna can cause limitation of forearm rotation, flexion and extension, deformity of the forearm, and seriously affect the function of affected upper limb. At present, the repair methods of segmental bone defects include vascularized autologous bone transplantation [1] , allogeneic bone transplantation, Ilizarov bone transportation [2] and personalized 3D printed prosthesis technology [3] . Because teenagers are still in the stage of growth and development, the treatment of segmental bone defect of ulnar needs to maintain the growth and development of ulna while reconstructing ulnar scaffold.…”

“…Their approach mirrors the importance placed on comprehensive evaluations in surgical interventions. Conclusively, a case report by Jiangang Cheng et al circles back to underscore the choice of titanium as the material for the implant [16]. This documents the repair of distal fibular and lateral malleolus defects utilizing an individualized 3D-printed titanium alloy prosthesis.…”

Background: The main objective of this study is to develop a customized metatarsophalangeal implant for the treatment of various conditions affecting this specific joint. This approach involves replacing the joint with a custom implant designed specifically to fit each patient's unique anatomical structure. The need for custom implants stems from the obvious lack of size variety available, which presents a major challenge when, the search for the ideal size implant can be a hard task, also when considering the possibility of extensive modification of the bone to adapt it to the available implant. This adaptation, often synonymous with bone reduction, can cause significant post-operative pain for the patient and impact healing time. Methods: A comparative study of modeling software was carried out to select the perfect software, by defining and comparing the relevant criteria. Similarly, the different biomaterial options were examined and compared to select the one best suited to this project, mentioning the imaging modality used to determine the types of images used for our approach. Finally, the 3D printers used in this work were represented, highlighting their technical characteristics. Findings: A resin metatarsophalangeal implant prototype was created using 3D modeling and reconstruction software and tools. Interpretation: Reconstruction and 3D modeling techniques are revolutionizing implant creation, offering customized solutions for patients suffering from metatarsophalangeal joint disorders caused by a wide range of diseases. These results have significant implications for disability management and rehabilitation, encouraging further exploration and progress.

Damaged support bores due to wear and ovality can be critical for a machine and its operation, in addition to representing a safety problem and risk of pin breakage. It can be a costly operation to perform the required repairs in between planned service periods, especially because of the unplanned down time. A joint with a standard cylindrical pin will often experience wear and ovality in the support bore surfaces, and at some point, repairs will have to be performed. This study investigates and compares five options when a joint with a cylindrical pin has reached a severe level of wear and ovality, outside its planned service stop. The work involved testing the viability of 3D scanning of the damaged bore surface, 3D printing of a metal bushing, and inserting the bushing into the damaged joint. In addition, two pin solutions, i.e., a standard cylindrical pin and an expanding pin type, were installed into the repaired joint, loaded, and the strain on the pin ends close to the supports was measured. For the sake of comparison, the supports had both smooth circular bore and severe wear and ovality. It was concluded that it is possible to produce and install the 3D-printed bushing insert without major problems; the insert had satisfactory capability during test loading, and it most probably represents a good solution when it comes to the reduction in unwanted downtime during unplanned repairs of damaged joints.
