A subtalar joint prosthesis that is adapted to replace the natural subtalar joint that exists between a patient's talus and calcaneus bones includes talar and calcaneal components. Each of these is configured to have a shape that is herein defined as being a portion of the boundary surface of a frustum. Meanwhile, these components' inner surfaces are configured to: (a) generally follow the anatomic contour of the original joint surface to which each component is to be attached, and (b) minimize each components's average thickness, consistent with providing sufficient strength and rigidity for the components, so as to require minimum bone resection for the implantation of these components.

A talonavicular joint prosthesis () adapted to replace the natural talonavicular joint that exists between a patient's talus and navicular bones, after appropriate surgical preparation of the joint-related portions of these bones so as to create a new joint space to accommodate this prosthesis, includes talar () and navicular () components. Each of these have inner () and outer () surfaces whose average separate distance is defined as the component's average thickness. These components inner () surfaces are configured to: (a) generally follow the anatomic contour of the original joint surface to which each component is to be attached, and (b) minimize each component's average thickness, consistent with providing sufficient strength and rigidity for the components, so as to require minimum bone resection in the creation of the new prosthesis-accommodating, joint space.

The present invention is directed to devices and methods that can be used in ankle surgery, especially ankle fusion surgery.

Medical devices for use during ankle fusion surgery

A protective member having a substantially flat base portion, and a substantially cup-shaped member extending from a forward end of the base portion. The base portion is attachable to a shoe, such that the cup-shaped member substantially encapsulates and protects a forefoot and toe region. Further, at least one opening is provided in a forward portion of the cup-shaped member to allow access to the forefoot and toe region. The cup-shaped member is further defined by an anterior portion extending upward from the base portion, a dorsal extension portion extending from an upper end of the anterior portion, where the dorsal extension portion provided to substantially cover a top portion of the forefoot and toe region, and at least one lateral extension portion extending from a side end of the anterior portion, where the at least one lateral extension portion provided to substantially cover a lateral portion of said forefoot and toe region.

Detachable post-operative protective device for the toes and forefoot

Devices and methods of manufacturing and using the same are provided for treating patients suffering from tendon dysfunction. Certain exemplary brace embodiments contain strapping systems and inflatable cells that are adapted to support the forefoot of the patient.

Devices and methods for adjustable foot correction

A technique and associated instrumentation for correcting large intermetatarsal angles that result from hallux valgus. The system includes a button and a suture loop attached to the button. A suture strand is threaded through holes in the button to attach the button to the suture. The suture ends are then brought together (by being swaged, spliced or cinched together, for example) to form the suture loop comprising a continuous, uninterrupted suture loop with a single strand of swaged-together ends. The swaged-together ends may be attached to a suture passing instrument such as a K-wire (Kirschner wire) that may be further used to drill a hole through the first and second metatarsals. The swaged-together ends of the suture are then passed through the drill holes in the first and second metatarsals; and the ends of the suture are pulled until the button abuts the second metatarsal. The swaged together portion of the suture loop is then cut, and the free suture ends are passed through holes in another (second) button. The suture ends are pulled to adjust the first metatarsal to a correct intermetatarsal angle, and the first metatarsal is secured in place by tying the ends of the suture together against the second button.

The intramedullary fixation device for use in fixing the relative position between a tubular bone and an adjoining bone has, according to the present invention, an intramedullary nail that is inserted into the medullary canal of the tubular bone whose position is to be fixed, an elongated blade for insertion into the adjoining bone whose position is to be fixed relative to that of the tubular bone, a coupling element for fixing and locking the relative position of the nail and blade after their insertion, and a means for locating and positioning within the bones to-be-treated the nail and blade. Furthermore, the blade has a cross-sectional shape that is configured in consideration of the geometry of the bone into which the blade is to-be-placed and so as to enhance the ability of the blade to stabilize the bone, and these elements are configured so that they do not have to be decouple during the process of inserting the nail and blade.

Modular, blade-rod, intramedullary fixation device

A device and method for treating a foot and ankle with a splint and an adjustable bladder. The method includes providing a device including a rigid splint that maintains a heel of the foot and at least one adjustable bladder provided underneath only a front of the foot; adjusting an inflation of the at least one bladder to a treatment inflation state; and maintaining a foot and ankle within the device for an extended period of time such that the foot and ankle are substantially immobilized in a dorsiflexion position or the foot and ankle are substantially immobilized in a position whereby plantarflexion is provided to the ankle.

According to a first embodiment of our invention, a monitoring device is placed above, within, or on the bottom of a cast, boot, shoe, or other lower extremity immobilization or protective device, and has one or more single or cluster of pressure sensitive chambers designed to burst at a predetermined force or weight. The pressure sensitive chambers may be filled with air, liquid, semi-liquid, or particulate material. Once properly positioned, the device serves to detect and alert one or more individuals to the fact that weight-bearing has occurred and/or that a certain amount of force has been transmitted across the bottom or other portion of the cast, boot, shoe, mat, sock, insole, or lower extremity immobilization or protective device in a setting where such pressure could be deleterious or harmful (including situations where patients are recovering from a bony fracture, tendon injury, and recent lower extremity surgery).
