System and method for a bunionectomy via bone cutting and fixation of a metatarsal in the foot

PendingUS20260069316A1Surgical sawsFastenersFifth metatarsal boneFirst metatarsal
A system and method for a ROSE-Reverdin / DARE osteotomy obviates severe deformities having a high intermetatarsal angle and which require closure via osteotomy (bone cut) of the first and / or fifth metatarsal in the midshaft or proximal aspect of the bone. The ROSE osteotomy is utilized to achieve this correction and is performed without need for fusion of the first metatarsal cuneiform joint. The ROSE osteotomy achieves correction of the intermetatarsal angle via rotation of the first and / or fifth metatarsal about a proximal based axis point. The Reverdin / DARE osteotomy is required to correct a deviated articular cartilage deformity at the head of the first metatarsal and / or additional slight correction of the IM angle. The Reverdin / DARE osteotomy achieves correction by wedging of the cut to realign the cartilage and translation of the head of the first metatarsal for further IM correction. A unique jig is used to achieve this cut and fixation.

Method and apparatus for pressure relief insole for footwear and natural shaped toebox for footwear

A shoe having an insole with pressure relief rings for cushioning the metatarsal heads of the human foot and inhibiting the forward slide of the foot into the toebox. The pressure relief rings are made from a low-density foam will the surrounding material of the insole are mad with a high-density foam. In various embodiments the pressure relief rings are hollow, solid like a disc, or have a depression into the low-density foam. The shoe is also provided with a natural toebox, in which the point of the toe is shifted to the inside of the foot to have a more natural fit for the asymmetry of the human foot.

Dermal cap for resurfacing bone joints

PendingUS20260053626A1Finger jointsAnkle jointsAnatomical structuresArticular cartilage
An apparatus and methods are provided for a dermal cap for resurfacing a metatarsal head of the foot or a metacarpal head of the hand. The dermal cap comprises an outer surface having a convex shape, an inner surface having a concave shape, and a rounded peripheral surface joining the inner surface and the outer surface. The inner surface can be placed onto a bone head such that the outer surface provides a bone head surface resembling the original articular cartilage. The outer surface effectively restores the articular cartilage and thus relieves pain and facilitates better joint function. The dermal cap can be formed by stretching it over a rounded mandrel shaped similarly to the size and anatomy of the bone head to be treated. The dermal cap can be freeze-dried on the rounded mandrel to set the desired anatomy of the dermal cap.

Metatarsal implant

A metatarsal implant for repairing damage in a metatarsophalangeal joint of a patient and in particular for repairing damage caused by osteofytes or as a result of osteofytes is provided. The metatarsal implant is adapted to be attached to an implant receiving surface at least partly covering a lateral surface of the metatarsal head. A bone contacting surface of the metatarsal implant is designed to correspond to the implant receiving surface, the bone contacting surface thus comprising at least two sub-surfaces in different planes, and at least one junction point where sub-surfaces meet, and a contour curvature of the articulating surface is designed by simulating a healthy articulating surface of the damaged metatarsal head, generated based on a determined surface curvature of the cartilage and / or the bone in a predetermined area at the site of diseased cartilage and / or bone, to mimic the original, undamaged, articulating surface of the metatarsal head.

Socks for diabetic patients

By simply wearing these socks, diabetic patients can effectively prevent ulcer formation while going about their daily lives indoors. This is achieved by physically supporting the arch of the foot, distributing the load on bony prominences such as the toes, metatarsal heads, and heels. [Solution] This sock 100 for diabetic patients is composed of a foot portion F that covers from the toes to the heel, including the instep and sole of the foot, and a leg portion L that extends from the foot portion F and covers from the ankle to at most below the knee. A large cushioning material 124 is provided on the inner surface of the foot portion F, approximately in the center of the sole of the foot, with a width approximately equal to the width of the foot portion F and a length of 1 / 2 to 2 / 3 of the length of the foot portion F. The cushioning material 124 physically supports the arch of the foot, thereby distributing the load on bony prominences such as the toes, metatarsal heads, and heels, and thus preventing ulcer formation.
