Abstract
Abstract A molding cast system for fractures of the humerus and of the radius and ulna that includes a molding cast having a wall member forming a substantially horizontal chamber for holding the forearm and a substantially vertical chamber for holding the upper arm, with an elongated aperture along the top of the horizontal chamber and an elongated aperture along the front of the vertical chamber. Connectors having fasteners hold the edges of the wall member defining the apertures together. A neck sling is affixed to the wall member. The wall member has an outer layer of soft flannel; a middle layer of a laminated plaster of paris casting material; and an inner layer of a flexible porous material next to the skin. The molding cast is prefabricated and can be shipped in a rolled condition to a hospital or doctor's office where it can be treated to be made pliable for specific application to a patient.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
282 words
A molding cast system for fractures of the humerus and of the radius and ulna of a patient, comprising, in combination, a molding cast including a wall member defining connecting, approximately cylindrical first and second chambers, said wall member having a pair of opposed, spaced elongated side edge portions and a pair of first and second end edge portion intersecting said side edge portions, said first chamber being adapted to receive the under part and the side parts of the forearm of the patient between the hand area and the elbow area, said second chamber being adapted to receive the rear and side parts of the upper arm of the patient extending from the elbow area towards the shoulder area, said first end portion defining a first opening at the outer end of said first chamber and said second end edge portion defining a second first opening at the outer end of said second chamber, said elongated side edge portions defining an elongated aperture opening to said first and second chambers along the top part of said forearm and the forward part of said upper arm between said first and second openings; said wall member including an inner layer of a flexible, porous material, a middle layer of a plurality of laminated layers of a casting material, and an outer layer of a flexible, soft, water absorbing and fast drying material; means affixed to said side edge portions for adjustably and removably connecting said side edge portion across said aperture; and means for adjustably supporting and positioning said molding cast, wherein said first chamber is maintained in a generally horizontal position and said second chamber is maintained in a generally vertical position.
