Devices and methods for removing a spinal disc are provided herein. Discectomy instruments are disclosed that can remove a spinal disc in a single-pass, i.e., without repeatedly inserting and removing the instrument from a patient. In an exemplary embodiment, the discectomy instrument includes a distal housing, at least one cutting blade, and a handle. When the distal housing is positioned adjacent to a spinal disc, a handle can be actuated to advance the cutting blade along a substantially arc-shaped path through the disc. In certain aspects, the path of the blade can correspond to the anatomy of the disc and to the approach used to access the spine. A second cutting blade can be advanced through the disc and can intersect with the arc-shaped path, forming a complete cut. The cut disc can be received in the distal housing and removed from the patient.

Methods and devices for removing a spinal disc

A surgical instrument support system has a support frame supported by three arms. Each arm has a plurality of ball and socket members strung in series along a cable. The arms are also connected to bases mountable to the patient's limb on the proximal and distal sides of the joint. Actuators are provided for each arm to change the tension in the cables to change the stiffness of each arm. The support system can be part of a surgical instrument system that includes a plurality of resection guides mountable to the support frame.

Surgical instrument system with ball and socket support

An instrument for orthopedic surgery comprising a block or cutting guide having a recess, and at least one locking device located on the cutting guide. The locking device is selectively movable between a first position in which a portion of the locking device covers a portion of the recess and a second position in which the recess is unobstructed. A bushing having a portion adapted to removably and replaceably mate with the recess on the cutting guide is also disclosed. The instrument is particularly useful for distal femoral augmentation in knee revision surgery.
