  • Patent number: 5766140
    Abstract: An angular compensation hinge for a human joint brace, as well as the brace into which the hinge is incorporated, are described. The hinge's hinge pin and leaves cooperate with an arch bar through guide pins and a bi-threaded screw to provide angular compensation adjustment of the brace. The hinge can be easily operated by the user without assistance and by rotation of a single screw, either with a simple tool or through a knob, and provides for infinite angular adjustment over the entire adjustment range. Adjustments can be easily made while the user is wearing the brace. There is positive locking of the hinge at any angle within the range of adjustment. A few standard sizes of the brace will be sufficient to provide essentially customized fitting braces for virtually any person because of the "fine tuning" capability provided. The hinge may be used with many different types of braces, including those intended for knee, wrist, elbow, ankle, hip and shoulder joints.

  • Patent number: 5645671
    Abstract: Disclosed is a method for manufacturing a composite pad from stock made of a relatively thin, sheet-like first layer, a relatively thin, sheet-like second layer and a relatively thick layer of an elastic, cushioning material sandwiched between the two. The outer layers are made of material, such as heat sealable material, that forms a seal under predetermined conditions. The pad is manufactured by first forming a sealed perimeter from the stock using a sealing tool and then using the same tool to separate the pad from the adjacent stock while simultaneously orienting the seal away from the side of the pad which will contact the wearer of a brace into which the pad is fitted.

  • Patent number: 5527268
    Abstract: A hinged orthopedic knee brace has a structural frame and at least one knee condyle pad attachable thereto. The frame has a plurality of rigid or stiffened support components dynamically connected by one or more hinges. The knee condyle pad is attachable to the frame proximal to the hinge and is configured to conform to the surface of the body overlying the lateral or medial knee condyle. The knee condyle pad has a fluid-containing primary bladder with a loop configuration encircling a depressed interior opening of the pad. The primary bladder is sized to circumscribe the periphery of the knee condyle and the interior opening is sized to receive the apex of the knee condyle. The distal portion of the primary bladder has a reduced volume and reduced surface area relative to the proximal portion thereof.

  • Patent number: 5501659
    Abstract: An ankle brace to be fitted about the lower leg and ankle of a wearer for inhibiting inversion and eversion of the ankle while accommodating plantar flexion and dorsiflexion is characterized by a rigidifying and unitizing external shell comprising a unitary member made of a rigid material and including a leg encircling portion at least substantially encircling the lower leg of the wearer and ankle stays extending downwardly from the leg encircling portion over the ankle and down to the heel on both the medial and lateral sides of the leg, the leg encircling portion accommodating flexing of the sides of the shell about a vertical axis intermediate the ankle stays for movement of the sides and the stays horizontally into supporting engagement with the medial and lateral sides of the leg and ankle, the shell preventing undesired movement of the ankle stays relative to one another.

  • Patent number: 5458565
    Abstract: An osteoarthritic knee brace is provided having flexible upper and lower arm members rotatably connected to each other by a rotary hinge assembly. A selectively inflatable or deflatable fluid-containing pad is positionable between the hinge assembly and a side of the knee joint. In operation, the brace is mounted on the leg with the pad engaging both the hinge assembly and the side of the knee joint, the hinge assembly aligned with the knee joint, and the upper and lower arm members aligned with the upper and lower legs, respectively. The upper and lower arm members are stressed away from the knee joint, thereby applying a restoring force to the knee joint across the hinge assembly and the pad that effectively treats the osteoarthritic knee joint. The restoring force is adjustable by selective inflation or deflation of the pad.

  • Patent number: 5454383
    Abstract: A method is provided for prefitting a stiffened member to a curved body having a geometry approximatable by a cone. Two points are initially selected on the surface of the body which also lie on two different planes passing through the body, such that the intersection of the surface and the planes defines two closed curves. A cone is approximated based on parameters relating to the curves and the selected points. A three-dimensional pattern of a stiffened member is then superimposed onto the conical surface at a modeling position corresponding to the desired placement position of the member on the body. The geometry and dimensions of the pattern are mathematically specified relative to the conical surface and the specifications provide a model for fabricating the prefitted stiffened member.

  • Patent number: 5409449
    Abstract: A hinge assembly is provided for an orthopedic brace having a rotatable hinge and a detent mechanism to automatically, yet releasably, lock the hinge in a fixed position of rotation. The hinge includes two rotatably attached members and the detent mechanism includes an indentation formed in the attached end of one member and a block pivotally mounted on the other member. The block has a locking projection that is biased toward the indentation and cooperates therewith to provide three positions of operation, a locked position, a release position, and an activated position. In the locked position, the locking projection fittingly engages the indentation, thereby substantially preventing rotation of the hinge. The release position displaces the locking projection a radial distance away from the indentation, thereby permitting the hinge to rotate freely.

  • Patent number: 5407420
    Abstract: An adjustable shoulder brace is provided for stabilizing and immobilizing the shoulder following an injury or surgical trauma to the soft tissue thereof. The shoulder brace is mountable on the arm and torso to isolate the shoulder and is fully adjustable across the abduction, flexion and rotation ranges of motion of the shoulder to enable fixation of the shoulder in virtually any rehabilitative position. The brace is made up of a series of rigid support members secured to the body of the patient, and a plurality of selectively rotatable and lockable joints adjustably interconnecting the support members. The combined effect of the joints simulates the entire range of motion of the shoulder.

The joints remain fully extended and flat in the kit, but when the splint is assembled from the kit, the contour joints are flexed to impart a u-shape to the support member conforming to the desired contour of the body.

  • Patent number: 5316547
    Abstract: An orthopedic brace is provided having one or more pads mounted thereon to provide secure and comfortable support for the brace when positioned against the body of a user. Each pad includes at least one pneumatic bladder, formed from a flexible skin permanently sealed to enclose a volume of gas therein. In a first embodiment, the brace has a point pad mounted thereon which is configured to conform to a surface of the body overlying a skeletal protrusion. The point pad contains a bladder having a substantially closed-loop configuration circumscribing the skeletal protrusion and having an interior opening to receive the protrusion. In a second embodiment, the brace has an areal pad mounted thereon which is configured to conform to a surface of the body overlying a curved, but relatively level, skeletal structure or soft tissue. The areal pad is a plurality of interconnected gas-inflated chambers that are maintained in fluid isolation from one another by flexible seams positioned between adjacent chambers.
