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.

A foot support device where the first metatarsal is raised with respect to the second through fifth metatarsals with a substantially horizontal support surface, the foot support device further having an arch support portion, the first metatarsal support allowing for a proper foot and ankle alignment for bipedal motion as well as standing.

The present invention is a method and device for the correction and reduction of bone deformities, such as metatarsus primus adductus, using a plate body with winged buttresses and dorsal loop. The method and device can be affixed to a bone without any drilling or violating of the bone and can use a tethering technique which does not require drilling into the second metatarsal, nor does it require the placement of a prominent suture knot / button device medially along the first metatarsal.

A stocking or sock with a foot portion includes a pocket for containing the big toe that is separate from the pocket(s) for the other toes. At least one medial reinforcement, integrally attached to the foot portion, entirely or partially surrounds the big toe pocket, while the medial part of the foot portion, and the posterior part or heel of the foot portion are anchored to the posterolateral or lateral part of foot portion, coming to bear on the anterior part of said pocket, counteracting any lateral deflections, and on the medial part, corresponding to the metatarsophalangeal joint and the first metatarsal of the foot, counteracting any medial deflections.

An orthopedic device is provided for treatment of Hallux Valgus. The orthopedic device includes a main part (3) in the form of an elastic sleeve, intended to exert a restraining force (F1) locally on the metatarsals (M1, M2, M3, M4, M5), a distal part (5) for encapsulating the big toe, and a connecting band (6) between the main part (3) and the distal part (5), intended to be tensioned in order to exert a lateral force (F2) on the big toe that is directed inwards in relation to the axis Δ of the human body. A pad (4) is secured to the inner wall of the device, creating a localized increased thickness, and arranged to be positioned against the first metatarsal of the big toe. The pad acts as an anchor during the application of the lateral force, in different positions of the foot, thus allowing the tensile force on the connecting band (6) to be adjusted. The combined restraining and lateral forces serve to re-align the joint during walking.
