Abstract: A unilateral external fixation device for closed reduction of simple or comminuted long bone fractures includes a frame formed of composite materials which mounts a proximal carriage at one end and a distal carriage at the other end. The proximal carriage is adapted to mount half pins inserted in the proximal segment, and is supported on the frame by support arms which are movable with respect to the frame for adjusting the position of the proximal segment. The distal carriage includes a clamping member adapted to mount half pins inserted in the distal segment, which is pivotal about the fracture to permit precise adjustment of the distal segment for alignment with the proximal segment. A fragment support, mounted to one of the side rails of the support arm for the proximal carriage, is adapted to clamp a half pin inserted within a central fragment positioned between the proximal and distal segments of a comminuted fracture.

Abstract: A tibial component for a unicompartmental knee prosthesis intended to be fitted without cement, comprises a metal base portion in the general form of a segment of a circular disc with generally flat upper, lower and lateral faces, the latter which is perpendicular to the others extending along the chord of the segment, and a periphery in the form of an arc of a cylinder, the lower and lateral faces being provided to bear against two notch surfaces provided in the plate of the tibia, respectively perpendicular to the general direction of the tibia and parallel thereto along the intercondylar eminence, and a plate member of polymer material which is fixed to the upper face of the base portion and forming a lining for the support of a corresponding condylar component, the base portion having on its lateral face at least one projection arranged to be driven in under the intercondylar eminence, at least one passage for a pinning means to engage into the subjacent bone in the vicinity of its periphery, and on its u

Abstract: Apparatus for training a person to walk with proper or improved pelvic posture. The apparatus includes a treadmill and mechanical means for controllably imposing a preselected pelvic posture on a person on the treadmill. A control circuit coupled to the mechanical means causes the mechanical means to impose a preselected pelvic posture on a person on the treadmill for a preselected training time period, and then releases the person's pelvis. Using this apparatus, a person walking on the treadmill can learn to walk with proper pelvic posture by first walking during a training time period with a preselected pelvic posture, and by thereafter walking without being restrained by the mechanical means while trying to maintain the pelvic posture position learned during the training time period.

Abstract: A suture anchor system that includes a drill for turning into a bone mass with sissoring blades pivotally connected in a longitudinal drill shaft slot proximate to a cutting end thereof, the blade ends to sissor to extend cutting edges outwardly therefrom, which sissoring occurs at a certain depth of penetration into the bone mass, cutting a flared or skirted hole therein, to receive a suture anchor whereto a suture is secured. The suture anchor consists of a suture rivet and slotted ring and is formed by moving the suture rivet into the slotted ring, that ring breaking at spaced apart slots formed therein and flaring into a skirt, the anchor rivet and slotted ring thereby locked together as the suture anchor, which suture anchor has approximately the same shape but a slightly lessor diameter than the hole formed in the bone mass.

Abstract: An addition to a leg extension and/or leg curl machine, which is used in fixing the positions of an operator's thighs while performing the leg extension or leg curl exercise movement. It is of a simple design which consist of two rigid, frame-journaled, rotating assemblies, one of which is "T" shaped and rotates about the axis of rotation of the machine's rotating effort arm, into and out of a position of engagement with the operator's thighs, and the other of which can be selectively rotated, through operator manipulation, about an axis which is both parallel with and offset from the axis of rotation of the first, into and out of a position of interference with the first. Working together, these two rotating assemblies constitute a quick-engage/release, rigid, thigh constraint device, which employs direct thigh constraint, and is both quicker to use and more comfortable than the non-rigid thigh constraint devices experimented with to date.

Abstract: A trunk stabilization device permits a standing user/subject to exercise and test hip abduction, adduction, flexion and extension with a conventional muscle exercise and testing machine such as the Cybex II system. A T-bar includes a vertical stem and two adjacent horizontal cross pieces. The stem is secured to the torque transducer unit associated with the machine such that the cross pieces extend horizontally and parallel to the torque axis of the transducer at a location between the transducer and the system support frame. A truck pad, preferably provided as part of the basic machine, is alternatively mountable in two mutually perpendicular and vertical orientations at an end of the cross piece. In one orientation the truck supporting surface is parallel to the torque axis; in the other orientation the axis and trunk supporting surface are mutually perpendicular.

Abstract: A portable Karate breaking-board holder, having an elongated-shaped frame, having an elongated top plate, elongated bottom plate spaced beneath the top plate and an elongated fence plate perpendicularly disposed between and attached to both the top and bottom plates. The fence plate defines distal and proximal recesses between the top and bottom plates. The breaking-board holder further includes board seating mechanism disposed along the distal edges of the top and bottom plates for seating at least one breaking-board in a plane at an angle to a plane perpendicular to one of the top and bottom plates. The breaking-board holder further includes an attaching mechanism coupled to the I-shaped frame which secures at least one breaking board to the distal edges to said top and bottom plates. Finally, handles are coupled to the I-shaped frame within the proximal recess.

Abstract: A novel device to be used in performing chest exercises is disclosed. It comprises two interconnected levers to which standard weight plates may be attached. A torsional spring provides resistance to the bringing together of the free ends of the levers. To use the device, a person, after affixing suitable weight plates to the device, lies on his back and grips the levers near their free ends. He then pushes the device upwardly in a bench-press type motion, and forces his hands together against the resistance of the spring. The novel U-shaped frame is of use in other standard exercises such as squatting movement, calf raises, bent over bows, and shrugs.
