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.

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.

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.

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.
