A discectomy tool comprising: a) a cannula having an outer surface having a longitudinal bore therein, a proximal end and a distal end; b) a steering wire disposed in the longitudinal bore; c) a flexible, hollow transmission shaft disposed in the cannula, the shaft having a throughbore, a proximal end portion, a distal end portion and an outer surface having a thread extending therefrom; d) an irrigation source fluidly connected to the throughbore; e) a cutting tip attached to the distal end portion of the transmission shaft.

Devices and methods for placing an implant between two bone portions are disclosed. In some embodiments, a method comprises disposing a portion of a flexible member through a first bone portion, through an aperture in a trial implant, and through a second bone portion. The trial implant can be withdrawn to enable an implant to be coupled to the flexible member. The method includes applying tension to the flexible member to urge the implant into the space between two bone portions. In some embodiments, the two bone portions are facets.

Disclosed are an extruded honeycomb catalyst, a process for preparing the catalyst, a method for reducing NOx in the exhaust gas from an internal combustion engine by using the catalyst, and a method for treatment of the emission gas generated from power plant comprising exposing the emission gas to the catalyst.

A method and apparatus for coupling a soft tissue implant into a locking cavity formed within a bone is disclosed. The apparatus includes a member to pull the soft tissue implant into a femoral tunnel. The member includes a suture having first and second ends which are passed through first and second openings associated with the longitudinal passage to form a pair of loops. Portions of the suture lay parallel to each other within the suture. Application of tension onto the suture construction causes retraction of the soft tissue implant into the femoral tunnel.

System and methods for channeling a path into bone include a trocar having a proximal end, distal end and a central channel disposed along a central axis of the trocar. The trocar includes a distal opening at the distal end of the trocar. The system includes a curved cannula sized to be received in the central channel, the curved cannula comprising a curved distal end configured to be extended outward from the distal opening to generate a curved path extending away from the trocar. The curved cannula has a central passageway having a diameter configured to allow a treatment device to be delivered through the central passageway to a location beyond the curved path.

A minimally invasive hip arthroplasty technique involves intramedullary insertion of an elongate femoral broach into a femur. The broach has a superior lateromedial transverse bore. A reaming rod is then located through the transverse bore and the neck of the femur. A cutting head is coupled to a distal end of the reaming rod via an incision. An orthogonal drive arm of an arthroplasty jig may also be inserted behind the cutting head to press the cutting head to ream the acetabulum while the reaming rod rotates the cutting head.

Described herein are cannulated reamer designs and methods. In one embodiment, a reamer comprises a cannulated central body portion, a plurality of cutting legs and outer frame. The cannulated central body portion has an inner wall surface and an opposing outer wall surface defining a thickness and a bone contacting surface and an opposing distal end surface defining a length, the inner wall surface defining a bore about a central longitudinal axis of the cannulated central body portion. The plurality of cutting legs extends outwardly from the cannulated central body portion. The other defines a periphery of the reamer, the outer frame coupled to a lateral end of each of the plurality of cutting legs. The cannulated central body portion has a recess extending entirely through the thickness and only partially though the length.

A discectomy tool comprising: a) a cannula having an outer surface having a longitudinal bore therein, a proximal end and a distal end; b) a steering wire disposed in the longitudinal bore; c) a flexible, hollow transmission shaft disposed in the cannula, the shaft having a throughbore, a proximal end portion, a distal end portion and an outer surface having a thread extending therefrom; d) an irrigation source fluidly connected to the throughbore; e) a cutting tip attached to the distal end portion of the transmission shaft.

A device comprises a base. A support is attached to the base. The support is shaped to receive a calf of a person and adapted to receive a wire or pin for securing a tibia of a person. A foot plate is attachable to the base. The foot plate has a plurality of attached members. The members are configured for receiving at least a first wire or pin to fix a foot of the person relative to the foot plate while the foot plate is oriented normal to a superior-inferior direction of the foot. The foot plate is rotatable relative to the base while the foot plate is attached to the base.

A system for coupling a tendon to a bone may include a tendon coupling device engageable with a tendon, a fastener to secure the tendon coupling device to the tendon, a bone coupling device, and a flexible element. The flexible element may include a first portion and a second portion. The first portion of the flexible element may be couplable with the fastener to securably attach the flexible element to the tendon. The bone coupling device may include a bone-facing surface engageable with a surface of the bone proximate a bone tunnel formed through the bone, and a hole formed through the bone coupling device. The second portion of the flexible element may be receivable through the bone tunnel and the hole formed through the bone coupling device to engage an opposing surface of the bone coupling device and securably couple the tendon to the bone.
