The ongoing Russo-Ukrainian conflict has resulted in a significant number of battlefield gunshot injuries, particularly characterized by severe bone defects. Traditional treatments such as bone grafting and external fixation have long repair cycles and poor adaptability, making it difficult to meet the clinical needs for rapid treatment and functional recovery in battlefield trauma, necessitating innovative surgical techniques.The Journal of Clinical Orthopaedics and Trauma published online in September 2025 a study titled “The utility of 3D-printed titanium grid scaffolds for the management of gunshot bone injuries in patients wounded in the Russo-Ukrainian war,”focusing on the application value of personalized 3D-printed titanium grid scaffolds in treating such injuries, providing important practical references for military orthopedic trauma treatment..
The study included 13 male patients injured on the battlefield between 2022 and 2023, all of whom had segmental bone defects. Preoperative radiological assessments were completed using X-rays and CT scans to accurately measure the defect size, bone density, and surrounding soft tissue conditions, providing a basis for surgical planning and scaffold personalization. Clinical data showed that the gunshot injuries primarily affected the femur and tibia, which are load-bearing long bones of the upper and lower limbs, with bone defect lengths exceeding 5 cm, and some cases accompanied by bone comminution, representing complex cases with high repair difficulty under traditional treatment systems.
The results confirmed that3D-printed titanium grid scaffolds exhibited three core advantages in treatment: first, the scaffold structure highly matched the anatomical morphology of the defect site, providing immediate support that meets biomechanical requirements and preventing postoperative bone displacement; second, the porous characteristics of titanium alloy material can induce bone cell adhesion and proliferation, effectively promoting bone regeneration and integration after large-area bone defects; third, the postoperative recovery period was shortened by more than 30% compared to traditional methods, significantly improving the efficiency of limb function recovery. It should be noted that some patients experienced joint contracture complications postoperatively, indicating the need for personalized rehabilitation training plans based on the characteristics of the injury site, but no serious adverse events such as scaffold loosening or infection occurred,confirming the overall safety and effectiveness of the treatment..
The conclusion is clear: severe long bone defects are a typical injury type caused by high-energy projectiles on the battlefield, and 3D-printed titanium grid scaffolds provide a feasible path for bone reconstruction in such injuries—especially suitable for patients with gunshot wounds and no active local infections (such as severe osteomyelitis) and acceptable soft tissue conditions. The core value of this technology lies inprecise preoperative planning, personalized defect repair, and accelerated rehabilitation processes, marking a transition in military medicine from “standardized treatment” to “personalized precise repair,” providing innovative technical ideas for emergency rescue of battlefield trauma and functional reconstruction after complex combat environments.
