Patient specific ankle-foot orthotic device

The unique advantages of computer-controlled fabrication of a patient-specific orthotic device using an automated fabrication machine capable of following computer instructions to create 3D surface contours and new developments in non-invasive three-dimensional (3D) scanning have made it possible to acquire digital models of freeform surfaces such as the surface anatomy of the human body and to then fabricate such a patient-specific device with high precision. Such a patient-specific device brings significant improvement in patient-specific fit, comfort, and function of medical devices (and, in particular, to orthoses that require a close fit to the wearer's body to act effectively). The combination of these two technologies is ideally suited for the development of patient-specific orthotic devices.A patient specific ankle-foot orthotic device using this technology is disclosed. This exemplary device is used to help stabilize the ankle-foot region, for example, in patients with impaired gait.

Knit elastic mesh loop pile fabric for orthopedic and other devices

An improved fabric for orthopedic devices is provided, being a knitted fabric produced on either a warp or weft knit system and utilizing a filament yarn selected from nylon and polyester as well as spandex. The fabric enhances freedom of movement while stimulating blood flow and muscle tone. The fabric has an elasticity that enables closure of orthopedic and other devices by placing the hook component of a Velcro (®) strip at any convenient point rather than aligning it with the loop component of the Velcro (®). The fabric is more convenient, faster and easier for many incapacitated persons, enhancing wearing comfort. Its mesh structure makes it more porous, which enhances the air circulation and the moisture management in creating a cooling effect on the wearer's skin and ready evaporation of perspiration, while still providing therapeutic warmth without heat buildup.

Footwear including an integrated orthotics system provides support with progressive resistance in pronation and supenation motions of the foot during a gait cycle. The orthotics system includes an orthotic device between the mid-sole and the outsole and extend from the rear foot's calcaneus region to the forefoot region where the phalanges and metatarsal joints meets. The orthotic device includes contours mimicking a foot sole shape in an unloaded state. The orthotic system may also include a secondary external orthotic device embedded underneath the outsole to provide control in the mid foot region to achieve progressive compression resistance in the mid foot arch zones. The secondary device may be customizable to achieve a wide range of resistance level needed in mid foot compression by the wearer. The orthotics combined with the midsole and outsole provide progressive mid foot compression resistance and directional flex associated with pronatory motions of the foot.

Implant with integral fastener retention

An orthopaedic implant provides a simple yet effective retention system requiring no additional components beyond the implant and the associated fastener(s). A plurality of anti-rotation protrusions on the fastener or screw head that match recesses in the implant. The protrusions engage the recesses to prevent the fastener from reversing direction, thereby assuring that the associated fastener does not backout during normal motion of the spine and other anatomical structures. A land on the fastener screw thread assures the fastener will not disengage from the implant should it strip out of the bone. Preventing the fastener from backing out assures it will not detach from the implant or staple, assuring that the implant will remain in place until all fasteners in the system have catastrophically failed. The anti-backout features of the invention provide feedback as they engage, allowing the surgeon to move quickly when placing a fastener without the concern for inadvertent over-tightening. Although ideally suited to a spinal correction system such as a cervical plate, the invention is applicable to other orthopedic devices, including plates and staples for other applications.
