Abstract
A crutch includes a grip and a forearm support that are coupled to an elongated member that extends from the forearm support to the ground. The inner surface of the forearm support can correspond to a digital representation of a forearm of the patient and the outer surface of the hand grip can correspond to a digital representation of a palmar surface of the patient's hand in at least a partially closed position.
Claims20
A custom crutch designed to be virtually fitted on a forearm of a patient prior to fabrication comprising:
- an elongated member having a distal portion and a proximal portion;
- a hand grip coupled to the proximal portion of the elongated member;
- and
- a forearm support coupled to the proximal portion of the elongated member;
- wherein the forearm support includes an elongated body and a first curved member and a second curved member that are rigidly coupled to the elongated body, wherein the first curved member is attached to a proximal portion of the elongated body and the second curved member is attached to a separated location near a central portion of the elongated body to define an elongate inner surface of the forearm support, and the inner surface of the forearm support is adapted to correspond a digital representation of the forearm of the patient and wherein the digital representation of the forearm is obtained by photogrammetrically processing a plurality of digital images of the forearm of the patient.

- a hand grip coupled to the proximal portion of the elongated member;
- and
- a forearm support body rigidly coupled to a first curved member and a second curved member, the first curved member turning upward and inward and the second curved member turning downward and outward to define a spiral configuration, wherein an inner surface of the forearm support is adapted to correspond to a digital representation of the forearm of the patient and wherein the digital representation of the forearm is obtained by photogrammetrically processing a plurality of digital images of the forearm of the patient.
