Device for external fixation of bone fractures with clamping of multiple pins and with a fixture for applying extension to bone fragments

摘要

A fixture is configured to provide external fixation of a fractured end portion of a bone by including a first number of holes for pins extending from the fixture into one or more fragments in the end portion and a second number of holes for pins extending from the fixture into the bone shaft. The second number of holes includes a hole within a sliding structure allowing a single pin to be moved with a fixture to provide extension between the fragments and the shaft. A first version of the fixture includes a sliding block through which rods extend to hold pins directed laterally into the fragments(s), and a sliding for clamping pins within the first number of holes. A second version of the fixture includes an arcuate portion in which the first number of holes extend in radial directions.
