Embodiment Construction

[0103] overview

[0104] Bunion correction or repair is a common surgical procedure with more than 100,000 procedures performed each year in the United States. Many surgical procedures for bunion repair are invasive and painful, requiring incisions of several inches and long recovery periods of up to 10-12 weeks. Minimally invasive procedures have been performed in plastic surgery for decades. One common procedure is called a Lapidus bunionectomy. In a Lapidus bunionectomy, the bunion is corrected at the big toe by adjusting the alignment of the first tarsal metatarsal joint. Bone screws and / or plates may also be used to stabilize the metatarsals to facilitate fusion between the metatarsals and the medial cuneiform.

[0105] However, the existing Lapidus bunionectomy has various disadvantages and risks. These disadvantages include not only the need for minimally invasive surgery, but also the need to use realignment devices with little control over the rotation and relativ...

Abstract

An improved surgical system and method for correcting deformity between first and second bones using correction factor-based alignment guides. The corrective factor may be based on a virtual model of the first and second bones in a deformed configuration and a corrective configuration. In the virtual corrective configuration, the first and second virtual axes may be secured in the respective first and second bones. The orientations of the first and second axes can be used to determine a correction factor when restored to the virtual deformed configuration. An alignment guide is used to insert one or more kirschner wires into each of the first and second bones in the deformed configuration. An orthotic guide is passed along the kirschner wire to rotate and / or translate the first bone relative to the second bone into an orthotic configuration.

Description

technical field [0001] The present invention relates generally to surgical systems and methods for correcting the alignment between two bones and joints, and more particularly to surgical systems and methods for correcting bunions in the foot of a patient. Background technique [0002] Misalignment and / or deformation of the bones can cause discomfort and reduced mobility in the patient's foot, especially in patients. One particularly common foot condition is bunions. A bunion is a progressive disease that usually begins with a tilt of the big toe. The tilt of the big toe gradually changes the angle of the bone and creates a characteristic hump on the inside of the metatarsal near the joint of the metatarsal and proximal phalanx. Specifically, a bunion is a protrusion, and sometimes an inflamed sac, made of bone. Hallux valgus is a condition in which the big toe deviates from its normal position toward the second toe. Accordingly, the present invention relates to surgical...
