    摘要: Treatment of spinal irregularities, including, in one or more embodiments, derotation apparatus and systems that can be used to reduce the rotation of vertebral bodies. Derotation apparatus that may comprise a tube assembly comprising an inner sleeve and an outer sleeve disposed over the inner sleeve. The inner sleeve may have a distal end for attachment to an implant. The tube assembly may further comprise a handle assembly. The tube assembly may further comprise a ball joint assembly disposed between the tube assembly and the handle assembly. The ball joint assembly may comprise a ball joint configured for attachment to a coupling rod. The ball joint assembly further may comprise a reducing extension below the ball joint, the reducing extension being sized to fit in a central bore of the inner sleeve. Orthopedic fixation devices comprising a ball joint are also disclosed.

    摘要: In one embodiment, a medical device includes an elongate member, a first coupler, and a second coupler. The elongate member has a first end portion, a second end portion, and a side portion. The side portion of the elongate member has a first receiving portion and a second receiving portion. The first receiving portion is configured to receive a first support member. The second receiving portion is configured to receive a second support member. The first coupler is coupled to the elongate member and is configured to engage the first support member to help retain the first support member within the first receiving portion. The second coupler is coupled to the elongate member and is configured to engage the second support member to help retain the second support member within the second receiving portion.
