Abstract
A bone plate has first and second sides, each with the same structure. The plate includes nodes separated by deformable bridges. Each node defines a screw hole, and wings extending laterally therefrom. The wings taper in thickness between the first and second sides. Screw holes are threaded into the nodes. The plate can be shaped to the bone by deformation at the bridges or removal of portions of the plate at bridges.
Claims20
A system for repair of bones, comprising:
- a) a first set of screws, the screws having a shaft and head with a square driver slot;
- and
- b) at least a portion of a screwdriver including a driver shaft with a proximal end and a distal end, the distal end defining a tip adapted to be received in the square driver slot of the first set of screws to both pick up and drive the first set of screws, the tip having at most four sides extending distally in a parallel direction, the sides meeting at corners that are rounded by a taper that tapers toward the distal end.
In a screwdriver for driving screws for orthopedic fixation, the screwdriver having a shaft, the shaft having a proximal end and a distal end, the improvement comprising:
- the distal end defining a tip having at most four sides of equal dimension, the sides meeting at corners that are rounded by a taper that tapers toward the distal end.
In a screwdriver for driving screws for orthopedic fixation, the screwdriver having a shaft, the shaft having a proximal end and a distal end, the improvement comprising:
- the distal end defining a tip having at most four sides that extend distally in parallel, the sides meeting at corners that are rounded by a conical taper that tapers between 3° and 5° toward the distal end.
