Abstract

Methods and apparatus for performing an osteotomy. One embodiment includes a kit comprising a bone plate, a bridging device, and a spreading device. The bridge is configured to hold open the incision in the bone, whether the spreading device is inserted into the bone, or the bone plate is attached to the bone. The spreading device preferably includes a scissors-type mechanism for spreading two wedge-shaped members apart, contemplating both pivotal and displacement movements of one wedging member relative to another wedging member. The spring device preferably includes an ergonomic grip for the hand of the physician, and a hammering surface useful in inserting the spreading device into the incision.

Dependent claims

A device for surgery on a bone, comprising:

a bridge having a peripheral wall that surrounds an open interior, the peripheral wall including a first peripheral wall surface portion, the first peripheral wall surface portion being arranged to face the open interior without facing the bone;
and
a plurality of standoffs, each of the standoffs having one end adapted and configured for contact with the bone and an opposite end supporting said peripheral wall, each of the standoffs being arranged to space the peripheral wall apart from the bone such that the open interior is elevated above the bone;
and
a plurality of elongated through bores, each of the elongated through bores extending from a respective one of the one ends to the corresponding opposite end and through the peripheral wall,
wherein said peripheral wall includes an opening located between at least two standoffs.
