Abstract: In an embodiment, a system attaches a patient reference array of a computer-assisted surgery system to a patient. The system includes a fixation post having a shaft having proximal and distal ends that are offset from. A threaded fastener is coupled to the shaft at the distal end that rotates relative to the shaft so as to engage internal threads of a pedicle screw, thereby causing the distal end of the shaft to translate in the anchor seat and urge the pedicle screw to transition from an unlocked configuration to a locked configuration. The attachment assembly has an arm that supports the patient reference array, and a coupler supported by the arm. The coupler has a fixation body that defines a recess that receives at least a portion of the fixation post, and an actuator that secures the attachment assembly to the fixation post.

Abstract: A metatarsal correction procedure may be performed so as to minimize the length of the surgical incision created during the procedure. A variety of different instruments and/or techniques and facilitate the minimal incision procedure. In some examples, a technique involves making a comparatively small surgical incision to access a tarsometatarsal joint. A metatarsal and a cuneiform separated by the tarsometatarsal joint can be prepared. In addition, the metatarsal can be moved relative to the cuneiform using a bone positioning device having a metatarsal engagement member positioned in contact with the skin of the patient on a medial side of the metatarsal. After moving the metatarsal, a fixation device can be installed across the tarsometatarsal joint to cause fusion. In some examples, a plate holder is attached to a U-shaped bone plate to facilitate plating across the joint through the comparatively small incision.

Abstract: A valve component 1 of the invention comprises a main valve 2 which is located on a centre line and at least one auxiliary valve 3 which is located radially outwardly of the main valve 2. The main valve may be used for sealing engagement with a cannula.

The auxiliary valves 3 may be utilised to introduce another instrument through the valve component. The valve component is mounted in a manner which ensures that the valve component 1 is rotatable about a centre line through the axis of the valve component 1. This ensures that the valve component 1 can be rotated relative to a cannula inserted through the main valve 2 and consequently that the auxiliary valves 3 are rotatable relative to the cannula allowing the auxiliary valves 3 to be positioned to facilitate optimum access and manipulation for an auxiliary instrument(s) inserted through the auxiliary valve(s) 2.
