Abstract: Systems, methods, and devices are disclosed that permit the use of hyperperfusion, or regional hyperperfusion to targeted areas by the use of an arterial and/or venous access system which allows repeatable, transcutaneous insertion without any need for repeat anesthesia. The systems, methods and devices use various combinations of catheters and/or balloons. Furthermore, systems, methods, and devices are disclosed that permit drugs or other treatment products to be delivered using hyperperfusion, or regional hyperperfusion, to targeted areas by the use of arterial and venous access system and associated catheters and balloons which allow repeatable, transcutaneous insertion without any need for repeat anesthesia.

Abstract: A reinforcement device (10) suitable for use with a prosthesis, such as a unicompartmental tibial component prosthesis. The reinforcement device is positionable between said component prosthesis and a surgically resected area of bone, for example, the tibia of a patient. The reinforcement device (10) includes a plate-like main body (12) extending from an anterior end (13) to a posterior end (14) and having an upper surface (16) and a lower surface (17). The lower surface (17) is engageable with a fixing means, such as a bone cement (25), to fix the tibial component to a surgically resected area of tibia. The main body (12) also has a plurality of perforations (15) therethrough.

Abstract: The invention comprises a method of reconstructing the anterior cruciate ligament in the right knee of a patient comprising the steps of forming a tendon graft of tendon, other soft tissue, ligament (including bone blocks if required), or artificial tendon; forming a hole into or through the lateral condyle of the patient's right femur from a point in the intercondylar notch therein, the hole extending anteriorly and laterally; forming a suitably positioned hole through the patient's right tibia opening at one end adjacent the medial tibial spine of the tibia; drawing one end of the tendon graft into the hole in the femur and simultaneously or sequentially drawing the other end of the tendon graft into the hole in the tibia; inserting the leading end of a suitable screw having a left handed thread into the hole in the femur from the intercondylar notch until the trailing end of the screw is at least adjacent he surface of the intercondylar notch; and after tensioning the tendon graft appropriately, securing t

Abstract: The present invention comprises a method for the reconstruction of a cruciate ligament of a patient. A connection device for connecting a cruciate ligament replacement graft to the femur of a patient is also described. The arrangement can result preferably in the femoral end of the graft being held in the femoral hole without any spring or elasticity in the connection between the graft and the femoral bone. At this end of the graft, at least, the practical and theoretical problems of screw fixation are avoided.

Abstract: A surgical screw has a head being, at least in a portion, hemispherical. A smooth continuous join exists between the head and a shank of the screw, the head being of the same, or larger, diameter as the shank. To drive the screw a drive socket is provided concentrically within the head, and a cannulation is provided concentrically of the shank and it opens into the socket so as to allow the screw to be threaded along a guide wire or similar. The shank has a smooth or soft thread so as to provide an interlocking fixation of a bone end of a tendon graft within a prepared hole of a bone, but without damaging either bone structures. The hemispherical portion provides a smooth continuous curved surface over which a graft may flex and move without fatigue or suffering stress concentrations.

Abstract: A process for removal of cement from the medullary canal of a patient's long bone comprising: determining the profile of a line of intersection of a plane, and a cement/bone interface intersected by that plane; determining the thickness of the cement in the plane; forming a substantially planar cutting blade with a cutting edge having a profile corresponding to the profile of the line; inserting the cutting blade into the cavity with the blade lying in the plane, the cutting edge directed towards the interface, and to a depth such that corresponding points of the cutting edge are adjacent corresponding points on the line causing the cutting blade to reciprocate; inserting into the cavity a guide member to urge the blade into the cement towards the cement/bone interface; removing the cement from the cavity.

Abstract: The removal of prosthetic cement from the medullary canal of a patient's long bone such as the femur during replacement of a joint prosthesis.

Abstract: A device (10) for measurement of laxity of the knee includes a thigh support (12) and foot support (13) so arranged that the leg of the patient will be bent at the knee when the patient's thigh is resting in the thigh support (12) and his foot is strapped to the foot rest (13). A potentiometer (26) measures movement of the tibial tuberosity of the patient's leg relative to the patella, and a strain gauge mounted on plate (15) measures the force applied by a patient seeking to straighten the leg such as by tensioning the quadriceps muscle. A computer (9) plots and displays a graph (8) or other output of the force applied against the relative movement between the tibial tuberosity and the patella.

Abstract: A device, and method of producing and using same, for use in removing the prosthetic cement from a bone in which an artificial joint (such as hip joint) is to be replaced. The device cuts the prosthetic cement in a longitudinal plane of the prosthetic cavity to the complete depth or the cement but without substantially cutting into the bone. The device includes a reciprocating saw head (8) which is advanced longitudinally of the cavity and maintained within the preselected longitudinal plane of the cavity by a guide (1) while it cuts through the cement (10). The saw head (8) is transversly biased towards the cement so that it cuts only to a depth defined by the profile of a template (6). The profile of the template (6) is obtained from X-ray information obtained before commencement of the operation.
