Treatment of Bone Defects Resulted after Excision of Enchondroma of the Hand in 15 Patients, Comparing the Techniques of Autologous Bone Graft, Injectable Bone Substitute and Spontaneous Healing
Background: Enchondroma is the most common benign bone tumor of the hand. Surgical excision of the tumor using curettage is the treatment of choice. The management of the resulting defects is still a controversial topic in the literature. Methods: This retrospective study includes 15 patients diagnosed with solitary enchondroma in the hand bones: eight cases with type A, three cases with type B and four cases with type D according to Takigawa classification. The aim of this study was to compare the course and outcome in the three patient groups treated by curettage associated with natural consolidation of the bone defect, autologous bone graft or injectable synthetic bone substitute in association with plate and screw osteosynthesis. Results: Outcomes were assessed using the DASH score (mean score 2.5) and TAM score (excellent in all patients) with no significant functional differences between the three groups. Defects managed with k-IBS® injectable bone substitute were associated with shorter operating time, simpler surgical technique and less postoperative pain assessed by VAS score. Conclusion: The use of k-IBS® bone substitute is efficient and less technically demanding than autologous bone grafting. The Takigawa classification could be a good indicator for treatment choice

Integration of Virtual Reality in the Control System of an Innovative Medical Robot for Single-Incision Laparoscopic Surgery
In recent years, there has been an expansion in the development of simulators that use virtual reality (VR) as a learning tool. In surgery where robots are used, VR serves as a revolutionary technology to help medical doctors train in using these robotic systems and accumulate knowledge without risk. This article presents a study in which VR is used to create a simulator designed for robotically assisted single-uniport surgery. The control of the surgical robotic system is achieved using voice commands for laparoscopic camera positioning and via a user interface developed using the Visual Studio program that connects a wristband equipped with sensors attached to the user’s hand for the manipulation of the active instruments. The software consists of the user interface and the VR application via the TCP/IP communication protocol. To study the evolution of the performance of this virtual system, 15 people were involved in the experimental evaluation of the VR simulator built for the robotic surgical system, having to complete a medically relevant task. The experimental data validated the initial solution, which will be further developed
