摘要： A cutting guide for performing a bone osteotomy procedure is disclosed. The cutting guide includes a first arm having a first cutting guide surface formed therein, a second arm having a second cutting guide surface formed therein pivotably connected to the first arm and a distractor operatively connected to the first arm. The cutting guide is adapted to be affixed to the bone such that the first cutting guide surface is open to the second cutting guide surface. The first arm and second arm are rotatable with respect to each other such that manipulation of the distractor creates a force between the first arm and the second arm causing rotation of the first arm and second arm relative to each other. A method for using the cutting guide in a bone osteotomy procedure is also disclosed.

摘要： A surgical instrument includes a deflectable cutting element extending from the distal end of the instrument. The deflection of the cutting element is controllable based on a user operating a moveable member of the instrument. The deflectable cutting element is normally disposed within a circumferential region defined by the distal end of the instrument. The moveable member can be moved in relation to the instrument to deflect the deflectable cutting element, such that the cutting element is at least partially outside of the circumferential region. The extent that the cutting element is outside of the circumferential region is a function of the position to which the moveable member is moved in relation to the instrument. The instrument further includes direct imaging of the distal end, such that the deflection of the cutting element for selective removal of bone tissue at the distal end of the instrument can be controlled in real-time.

摘要： Instruments and a method for preparing the articular surface of the patella to receive a patellar implant are utilized without everting the patella. A medial or lateral parapatellar incision and an anterior midline incision are made adjacent the patella. The patella is clamped with a patella clamp, a hole is drilled from the anterior surface of the patella. A reamer is inserted through the medial or lateral parapatellar incision and is then attached to the end of a drive shaft that extends outwardly beyond the articular surface of the patella. The posterior facing cutting surface of the reamer device is then placed in contact with the articular surface. The drive shaft is then rotated and moved anteriorly causing the cutting surface of the reamer device to remove a desired amount of patellar cartilage and bone to accommodate a patellar component. The patellar component is secured into place by aligning a central peg protruding from the top surface of the patellar component with the previously drilled hole in the patellar remnant.

摘要： A method of preparing a knee joint for receiving a unicondylar knee implant includes preparing a first seating surface at a proximal end of a tibia, and providing a combination bur template and spacer block, the bur template having an upper end, a lower end and a curved surface extending between the upper and lower ends thereof that is adapted to conform to a femoral condyle of a femur and the spacer block extending from the lower end of the bur template and having top and bottom surfaces. The method includes flexing the knee joint so that the prepared first seating surface at the proximal end of the tibia opposes a posterior region of the femoral condyle and inserting the combination bur template and spacer block into the knee joint so that the top surface of the spacer block engages the posterior region of the femoral condyle and the bottom surface of the spacer block engages the first seating surface at the proximal end of the tibia. While the spacer block is maintained between the femur and the tibia, the knee joint is extended until the curved surface of the bur template engages the femoral condyle of the femur. The bur template is anchored to the femur and used to guide burring of the femoral condyle for preparing a second seating surface on the femur. After burring the distal end of the femoral condyle, the posterior region of the femoral condyle is resected.

摘要： A modular humeral head system includes a housing having an outer surface and an inner surface. A hemispherical socket formed on one end of the inner surface and threads formed on the other end of the inner surface. A cap is attached at the threaded end of the housing. The cap has one or more threaded holes that run from the top surface to bottom surface of the cap. A screw may be inserted in each hole. The modular humeral head system also includes an intermediate piece having a hemispherical head at one end of a tapered shaft. The tapered shaft is inserted in a humeral stem. The hemispherical head and the hemispherical socket form a ball and socket coupling. A trial head may be impacted on the housing. The trial head has one or more holes that are aligned with the screws inserted in the cap.In use, the assembly of the trial head, cap and housing can be adjusted to be in any angular orientation about hemispherical head. The tightening of the one or more screws fixes the angular position of the trial head. An optimum position for the trial head is established via trial reduction, the one or more screws tightened to fix the position of the head and the trial head is replaced with a humeral head of corresponding size and shape. The maximum adjustment of the angular position may be limited by a limiting mechanism. In another embodiment, bone cement or other bio-compatible material is introduced in a chamber formed between the cap and the hemispherical head.

摘要： A device and method for aspirating fluid from a body cavity are disclosed herein. The device disclosed utilizes a reservoir in fluid communication with a needle via a tube connected to a pump. The needle is able to displace a desired distance. Further, the aspirator includes a selector switch capable having three positions. In the first position anticoagulant is pumped through the system. In the second position bone marrow is aspirated but the needle is not moved. In the third position the displacement of the needle is controlled as well as the volume in the reservoir. Further, in the third position, the volume in the reservoir and the needle displacement are proportional to one another.
