[0009]From the photographs, a three dimensional digital representation of the limb can be created by photogrammetry, image correlation, depth mapping or any other suitable IR and/or visible light photography based surface topography detection method. From the three dimensional representation of the limb surface topography, a spiral brace can be designed having an inner surface that corresponds to the three dimensional digital representation of the patient's limb. The measurements of the markers or markings from the photographs can be more accurate than measurements of other surface points on the patient. Because the markers can provide more accurate position measurements, the markers can be used for important design data points for the digital representation of the limb and the design of the spiral brace.
[0010]In an embodiment, the brace or cast has a smooth inner surface that conforms to the digital representation of the scanned surface of the limb and closely matches the surface measurements of the patient's body. Because the inner surface of the brace accurately conforms to the patient to provide a very

[0023]The present invention is a custom designed spiral brace. The term “spiral” is used to describe the three dimensional curve of a brace that wraps at least one full circumferential turn around an axis of the limb in a generally helical shape. The spiral brace can also have interior surfaces that correspond closely to a digital representation of a portion of a patient's body which can be from an optical scan or photograph(s) of the patient. When a patient injures a limb, the spiral brace can be designed to closely fit around the limb. In order to provide a close fit around the limb, the interior surfaces can be slightly larger than the digital representation of the portion of the patient's body. Thus, the interior surfaces are not an exact match but correspond to the digital representation of the patient's body. The inventive spiral brace can be designed to resist specific types of movement. For example, a spiral brace can be an arm brace that allows movement of the fingers and t...

Abstract
A spiral brace has an inner surface that corresponds to a digital representation of an injured limb. The spiral brace can wrap around a length of the limb in a helical manner. The body of the spiral brace may be a single piece structure that is fenestrated to provide air circulation to the injured limb.
