Reduction of fractures in the minimally invasive (MI) manner can avoid risks associated with open fracture surgery. The MI approach requires specialized tools called percutaneous fragment manipulation devices (PFMD) to enable surgeons to safely grasp and manipulate fragments. PFMDs developed for long-bone manipulation are not suitable for intra-articular fractures where small bone fragments are involved. With this study, we offer a solution to potentially move the current fracture management practice closer to the use of a MI approach. We investigate the design and testing of a new PFMD design for manual as well as robot-assisted manipulation of small bone fragments. This new PFMD design is simulated using FEA in three loading scenarios (force/torque: 0 N/2.6 Nm, 75.7 N/3.5 N, 147 N/6.8 Nm) assessing structural properties, breaking points, and maximum bending deformations. The PFMD is tested in a laboratory setting on Sawbones models (0 N/2.6 Nm), and on ex-vivo swine samples (F = 80 N ± 8 N, F = 150 ± 15 N). A commercial optical tracking system was used for measuring PFMD deformations under external loading and the results were verified with an electromagnetic tracking system. The average error difference between the tracking systems was 0.5 mm, being within their accuracy limits. Final results from reduction maneuvers performed both manually and with the robot assistance are obtained from 7 human cadavers with reduction forces in the range of (F = 80 N ± 8 N, F = 150 ± 15 N, respectively). The results show that structurally, the system performs as predicted by the simulation results. The PFMD did not break during ex-vivo and cadaveric trials. Simulation, laboratory, and cadaveric tests produced similar results regarding the PFMD bending. Specifically, for forces applied perpendicularly to the axis of the PFMD of 80 N ± 8 N deformations of 2.8, 2.97, and 3.06 mm are measured on the PFMD, while forces of 150 ± 15 N produced deformations of 5.8, 4.44, and 5.19 mm. This study has demonstrated that the Georgilas et al. Manipulation Device for MI Surgery proposed PFMD undergoes predictable deformations under typical bone manipulation loads. Testing of the device on human cadavers proved that these deformations do not affect the anatomic reduction quality. The PFMD is, therefore, suitable to reliably achieve and maintain fracture reductions, and to, consequently, allow external fracture fixation.

This paper presents a safety analysis of a Robotic Fracture Surgery System using the Systems-Theoretic Process Analysis (STPA). It focuses particularly on hazards caused by the human in the loop. The robotic system and operating staff are modeled including information flow between different components of the system. The analysis has generated a set of requirements for the system design that can ultimately mitigate the identified hazards, as well as a preliminary set of human factors that can improve safety.

La ingeniería biomédica, surgió como una aplicación de los principios de la ingeniería en las ciencias de la salud 1 , permitiendo el desarrollo y fabricación de dispositivos mecánicos como prótesis y órtesis, bombas de infusión para la administración de medicamentos 1 y bioequipos implantables como marcapasos cardíacos e implantes cocleares. Además, se encarga del diseño de circuitos eléctricos y software informáticos para instrumentación médica, desarrollo de ayudas diagnósticas, como radiografías convencionales, tomografía computarizada e imágenes por resonancia magnética, que han revolucionado el diagnóstico y el tratamiento en la medicina actual, apoyado en las diversas disciplinas de las Ciencias Biomédicas 1 .Es por ello, que los programas universitarios que desarrollen está carrera requieren que los estudiantes cursen estudios de ingeniería tradicional y cursos relacionados a la comprensión de la complejidad de los sistemas biológicos; sin embargo en el Perú, son pocos las instituciones educativas que brindan está carrera, tanto en pregrado como en postgrado, mostrando un retraso de más de 30 años en comparación con la realidad mundial -incluso con países de la región-, como se muestra en la tabla 01 2 .El organismo internacional que representa a nivel global la Ingeniería Biomédica es la International Federation for Medical and Biological Engineering (IFMBE) cuya misión es alentar, apoyar y unificar la comunidad de Ingeniería Medica y Biológica en todo el mundo, con el fin de promover la salud y la calidad de vida por medio del avance de la investigación, el desarrollo y la gestión tecnológica Programa País Ingeniería
