Orliman left palmar flexion-extension elbow orthosis. External device for the elbow joint. Elaborated by means of a metallic shell to immobilise the arm and another shell to immobilise the forearm. Both are joined together through a mechanically designed joint using software. This allows the flexion and extension movement of the limb muscles from 0° to 90°. Anatomically shaped and perforated to allow perspiration to evaporate quickly. Externally it is lined with velour fabric with a velvet finish. Internally it has a hypoallergenic fabric that helps reduce the risk of provoking an allergic symptom. The orthosis makes it possible to completely immobilise the upper limb, which promotes recovery. It is designed with velour closure and a pin buckle to adjust it in a personalized way.
