Abstract

A device for correcting a compression-type fracture includes a housing at a proximal end of the device, a cannula extending from the housing and through a directional balloon, and a tip at a distal end of the cannula, wherein the cannula has an outer tube for supplying fluid to the balloon and an inner tube positioned within the outer tube for supplying cement through at least one opening in the distal end of the cannula. A method of using the device is provided, wherein the device is inserted into a fracture site, the balloon is inflated to elevate fragments of the fracture, cement is injected into the opening created by elevating the fragments of the fracture and the device is removed from the fracture site. The balloon may be deflated before the injection of the cement or simultaneous with the injection of the cement.

Description

[0001] Cross references to related applications [0002] This application claims the priority of US Provisional Patent Application No. 62 / 611,134 filed on December 28, 2017, the entire disclosure of which is expressly incorporated herein by reference. Technical field [0003] The present invention relates to a device for correcting compression fractures, including intra-articular fractures in which the fracture crosses into the surface of the joint (especially at the ankle joint or heel), and a method for correcting compression fractures using this device . Background technique [0004] Ankle fractures are one of the most common persistent fractures, with more than five million ankle injuries reported in the United States each year. Heel or calcaneal fractures, although less common, are usually even more debilitating. These fractures are usually of the intra-articular type, where the fracture breaks across the joint into the surface and therefore requires particularly careful mana...
