Abstract: An orthopedic brace for rigidly supporting a human arm and shoulder, having a positioning rod for infinitely varying the elevation of the arm through a coarse adjustment and a fine adjustment, and having universal joints on the positioning rod for infinitely varying the orientation of the arm.

Abstract: An improved arm sling includes a forearm support section having a resealable opening in a bottom panel for permitting exercise, flexure and extension of a patient's forearm without removing the sling harness from the patient. A splint pocket is also provided for housing a removable splint for supporting the patient's hand in a neutral position. An external pocket encloses a foam cushion for conforming engagement with the patient's waist, thus providing an abduction effect.

Abstract: A glenoid prosthesis and method for affixing the same to a resected portion of a glenoid cavity on the head of the scapula. Th glenoid prosthesis has a lateral surface for articulating with the humeral head and a flat medial surface which engages a flat surface resected from the glenoid cavity. In a first embodiment, a pair of pegs extend medially from the flat medial surface of the glenoid prosthesis which are positioned in a pair of holes and the mating flat surfaces and pegs and holes are bonded with cement. The flat mating surfaces resist rocking under applied superior-inferior loading. Resection of the bone is simplified by providing a flat resected surface and holes drilled substantially perpendicular thereto. Preferably, grooves are provided in the pegs to provide an increased area for bonding, and preferably the grooves are graduated in depth to provide greater strength at the proximal end of the pegs where the highest stresses occur.

Abstract: A glenoid prosthesis and method for affixing the same. The glenoid prosthesis has a lateral surface for articulating with a humeral head and a flat medial surface which engages a flat resected surface on the scapula head. In a first embodiment, an integral plastic prosthesis has a pair of pegs extending from a flat medial surface which are positioned in a pair of holes drilled in the bone. The mating flat surfaces and pegs and holes are bonded with cement. The flat mating surfaces resist rocking under applied superior-inferior loading and resection is simplified by providing a flat resected surface and holes drilled substantially perpendicular thereto. Grooves are provided in the pegs to provide an increased area for bonding and the grooves are of graduated depth to provide greater strength at the proximal end of the pegs where the highest stresses occur.

Abstract: A modular humeral prosthetic device comprising a humeral stem having a substantially cylindrical distal end for insertion within the medullary canal of a resected human humerus; the stem transforming proximally from the distal end into a widened proximal end being tapered from anterior to posterior aspect; the proximal end having a proximal end surface which is angled relative to the axis of the distal end; a collar extending from the proximal end surface for preventing the stem from subsiding within the medullary canal; a tapered cylindrical mounting lock mechanism disposed on the proximal end surface, the axis of the tapered cylinder being substantially coincident with the central axis of the proximal end surface; a head mechanism having a substantially spherically shaped outer surface for engagement within the glenoid cavity of a human scapula, the outer spherical surface of the head mechanism being less than half the surface of a complete sphere; the head mechanism including a complementary tapered apertu

Abstract: A device for guiding an osteotomy to be performed on the proximal end of a humerus that has a proximal sawguide alignable on a selected surface of the proximal end of the humerus for defining a saw line thereon; a radial arm connecting the sawguide to a distal mechanism for stably aligning the sawguide, the distal alignment mechanism has a pair of opposing lateral and medial epicondyle arms pivotally engageable with the lateral and medial sides of the distal end of the humerus, the epicondyle arms being pivotally mounted in a distal cross arm, the distal end of the radial arm being slidably mounted in the cross arm for distal to proximal slidable movement therein; the proximal end of the radial arm being rotatably connected to the sawguide through a proximal guide bar; the radial arm being supported above the humerus by the proximal guide bar and the epicondyle arms.
