  • Patent number: 5662595
    Abstract: A supination-pronation orthosis for the elbow joint of a patient which includes a hand and wrist cuff secured to the hand and wrist of the patient and an upper arm cuff secured to the upper arm of a patient to extend from adjacent to the elbow joint outwardly along the upper arm. A flexible torsion unit is mounted to extend between the upper arm cuff and the hand and wrist cuff along the forearm of the patient.

  • Patent number: 4772012
    Abstract: A postoperative dynamic splint for controlled mobilization of a digit following tendon repair consists of a supportive brace assembly, having an attachment member for attachment of said brace assembly to the distal portion of the arm and the proximal portion of the hand and a tensioning unit which comprises a housing mounted on the supportive brace assembly, a spiral torsion spring mounted at one end to said housing and terminating at its other end to a work arm, which extends out of said housing. The work arm attaches to a rubber band, which is trained under a rotatable roller, mounted on a bracket attached to said brace assembly and at the other end to a connecting member, such as a nail cover, for the affected digit. This allows for extension and flexion of the recuperating digit, so as to prevent adhesion of the tendon to the tendon sheath during the healing process and thus insure full use of the digit after healing.
