SEQUENTIAL SERIES OF ORTHOPEDIC DEVICES THAT INCLUDE INCREMENTAL CHANGES IN FORM
First Claim
1. A sequential series of individual ankle foot orthotic (AFO) devices that are custom fitted for a foot of a patient and that vary incrementally from one to the next in a flexion angle, the series of devices comprising an initial device, a final device, and at least one intermediate device, each individual AFO device of the sequential series comprising:
- a posterior strut defining a vertical axis and having a proximal end and a distal end; and
a foot support portion coupled with the posterior strut at or near its distal end, wherein the foot support portion is custom fitted for the foot of the patient, and wherein the foot support portion comprises;
a foot bed, comprising a bottom surface defining a bottom plane of the individual AFO device; and
an ankle cover removably connected to the foot bed,wherein a vertex of the vertical axis of the posterior strut and the bottom plane of the foot bed defines the flexion angle, andwherein an overall configuration of each individual AFO device of the sequential series of AFO devices is determined at least in part by a single digital profile of the foot of the patient.

Abstract
A method is described for fabricating a sequential series of orthopedic devices custom designed to change a configuration of a body part of a patient from a pretreatment configuration to a treated configuration. The method involves receiving digital data representing the body part of the patient in the pretreatment configuration. The method continues by generating, using the digital data, a sequential series of digital 3D body part models, including at least an initial body part model representing the pretreatment configuration of the body part, a final body part model representing the treated configuration of the body part, and at least one intermediate body part model representing the body part in an intermediate configuration between the pretreatment and treated configurations. The method further involves fabricating the sequential series of orthopedic devices from the sequential series of digital 3D body part models.
