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.

Methods and apparatuses for treatment of various joint conditions include a device inserted into a joint space. During delivery, the profile of the device is constrained in at least one dimension to minimize invasive impact on tissue and / or bone. The device may be restrained for implantation by a thread or a rigid elongate member. After insertion, the device may expand at the implantation site.

Composite orthopedic devices that facilitate spine stabilization, such as: bone screws, rods, plates, interbodies, and corpectomy cages are disclosed. They are designed to provide both strength and load carrying capabilities, while increasing bio-integration of the devices with the surrounding bone tissue. They are constructed of composite layers of allograft and / or autograft bone and a structural material, such as titanium alloy or carbon / graphite fiber composite. Cannulations within the device are loaded with a mixture of stem cells, particles of allograft and / or autograft bone, and bone growth factors, such as BMP-2. The cannulations are connected to the surface of the device via multiple fenestrations that provide pathways to supply the bone / stem cell mixture to the surface, allowing living bone tissue to grow and insure bio-integration. The devices can also have radiofrequency (RF) stimulation implantation within the structure of the implanted device, capable of responding to external RF stimulation of enhanced bone growth.

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.

A fixation system configured to releasably secure an orthopedic implant to a bone. The orthopedic implant has at least one lumen extending from a proximal portion to a distal portion configured to extend through cortical portions and into cancellous portions of the bone. The fixation system includes a flowable biomaterial that flows through the lumen into the cancellous portion of the bone in an expanded configuration with at least one dimension greater than a corresponding dimension on the orthopedic implant located generally along a pull-out direction of the orthopedic implant. An insert is positioned in the lumen and in engagement with the flowable biomaterial located in the cancellous portion of the bone, such that the orthopedic implant is detachable from the biomaterial in the cancellous portion of the bone to facilitate subsequent removal of the orthopedic implant from the bone.

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.

The present invention provides an orthotic appliance for the carpus of a human hand for the treatment of a carpal tunnel syndrome condition using co-dynamic, rather than traditional static or dynamic, techniques. The appliance may apply a dorsally-directed force to the region of the pisiform bone (23) in the neutral carpal position of a human hand upon co-contraction of the hand and up to 8 pounds dorsally-directed during arc of motion in carpal flexion, as the wrist and hand is encouraged to actively move in all planes of motion without restricting arc of motion or negatively affecting the normal activities of daily living. The appliance may comprise a biasing structure for applying the dorsally-directed force and a base structure for maintaining the biasing structure in its proper configuration during normal hand motion.
