Resumen

The ankle, a pivotal and intricate joint within human anatomy, is particularly susceptible to injuries, notably sprains, due to its complex structural composition and the substantial load it endures, especially among high-performance athletes, thereby necessitating the development of innovative, patient-specific rehabilitation solutions to address the challenges presented during the recovery process. In response to this, a non-surgical approach is proposed, involving the meticulous design and implementation of a personalized orthosis. It will be designed employing additive manufacturing with polyethylene terephthalate glycol (PETG), which facilitates immobilization while also enhancing breathability and comfort through the strategic incorporation of hexagonal holes. It demonstrates significant promise in its innovative design, customizability, and potential applicability, contributing to the broader field of biomechanics and orthopedic rehabilitation.
