Estimating the term…
The present invention provides a new and improved orthosis for use in effecting relative movement between bones in an arm of a patient. The apparatus includes a lower cuff gripping distal bone, such as a wrist, and an upper cuff gripping a proximal bone, such as an upper arm. The lower cuff is secured in a rotatable drive assembly substantially coincident to a longitudinal axis of a medial bone, such as the forearm, during rotational distal adjustment. The angle between the forearm and the upper arm is adjustable and can be securely fixed at a desired angle. The rotation of the rotatable drive assembly effectuates the pronation and supination of the hand and wrist relative to the patient's forearm. The orthosis of the present invention can be disassembled with interchanging parts substituted depending on the patient's needs.
An orthosis apparatus for rotating a medial bone of an appendage relative to a proximal bone of the appendage about a longitudinal axis of the distal bone, the appendage having a distal bone connected to the medial bone, said apparatus comprising:
An orthosis apparatus for rotating a bone about a bone axis, comprising:
An orthosis apparatus for rotating a forearm about a forearm axis, the forearm being connected to a wrist an elbow, the orthosis apparatus comprising:
An orthosis apparatus for rotating a forearm about a forearm axis, comprising
In an orthosis apparatus for rotating a forearm about a forearm axis including an arcuate member rotatable about an arcuate member axis, an array of gear teeth disposed about said arcuate member, a drive gear mechanically communicating with said gear teeth and configured to rotate said arcuate member about said arcuate member axis whenever said drive gear is rotated, said drive gear having an axle, the improvement comprising:
A method for performing an orthosis on an appendage having a distal bone, a medial bone, and a proximal bone, which comprises:
A method of preventing an orthosis apparatus from unintentionally rotating, which comprises:
