Adaptive three-dimensional orthoses and methods for their manufacture and use

Abstract

A conformable body interface is fabricated using a data set representing a three- dimensional, soft tissue body surface. The conformable body interface includes a body scaffold that is divided into two or more longitudinal segments separated by axial joints. Optionally, the body scaffold is further divided into two or more circumferentially split segments separated by circumferential joints. The axial joints are circumferentially constrained by elastic bands, tabs, or similar structures and the circumferential joints are longitudinally constrained by elastic axial tethers or similar structures. In this way, the body interfaces can accommodate swelling and bending of the body surface.

Background technique [0003] 1. Field of invention. Although orthopedic interventions for physical rehabilitation have been known for centuries, splints, casts, and other orthotics present challenges in their implementation. From splints made of sticks and casts made of plaster for temporary fixation, the field has progressed to the manufacture of dynamic orthoses from advanced composite materials. More recently, the field has evolved to use 3D scanning and printing techniques to produce 3D orthoses that are individualized to the patient's anatomy. [0004] The primary function of any cast or splint is to provide...
