Abstract: The invention provides a wire delivery device, suitable for use in removing bony ingrowth from an implant such as a femoral implant. The wire delivery device comprises first and second elongate bodies and holds and provides cutting wire in the form of medial and lateral cutting wire arcs. The cutting wire can be used to cut by pushing the first and second elongate bodies in an alternating motion in the desired direction of cutting.

Abstract: Hip arthroplasty trial systems and associated medical devices, methods, and kits are described that can be utilized in situ to complete a femoral head trial. An example embodiment of a hip arthroplasty trial system includes a medical device and a femoral stem. The medical device has a head member, a spacer, a shaft, and a locking member. The spacer is disposed within the head member and is moveable from a first position to a second position. The shaft is disposed within the head member and contacts the femoral stem. The shaft is moveable from a first position to a second position. Movement of the shaft from the first position to the second position moves the spacer from its first position to its second position. The locking member is disposed within the head member and releasably attaches the shaft to the head member.

Abstract: Surgical tools which are used to separate from one another a femoral cup and an acetabular ball in an implanted hip replacement prosthesis. At its distal end, elements of the surgical tool engage the femoral cup and the acetabular cup. When proximal handles of the tool are squeezed toward one another, the engagement elements move away from one another. Thus, a surgeon is able to separate the femoral cup and the acetabular ball from one another without pulling the acetabular cup away from the acetabulum or the femoral cup and/or femoral implant away from the femur, thereby accomplishing the separation without disrupting any bone ingrowth.

Abstract: The present application is directed a Joint Revision Surgery System and Method which includes a surgical osteotome blade guide block which has a plurality of rearward blade guide slots, a central cavity and a plurality of forward guide slots having a two-way adjustable L-shaped guide plate. The surgical osteotome blade guide block central cavity houses a stem trunnion securing and is secured to the prosthesis to be extracted. The guide blade block is secured to the trunnion of the prosthesis to be extracted using a stem trunnion securing member housed within the guide block. Straight, curved, flexible and rigid and compound curved osteotome blades are guided by the blade guide slots to cut the implant free from the bone. The Joint Revision Surgery System and Method facilitates rapid, efficient and complete removal of an existing prosthesis during joint revision surgery, and significantly increases positive medical outcomes for joint revision procedures.

Abstract: An implant removal tool (1) used to remove a femoral implant (17) from a femur bone (18) by providing a substantially U-shaped body (2) having a substantially rectangular-shaped opening (9) located thereon that allows the substantially U-shaped body to be placed over a neck (21) of a femoral implant so a sharpened front edge (5) of the substantially U-shaped body makes direct contact with an inner surface of the stein of the femoral implant. The U-shaped body may have front side edges (26, 27) that extend beyond a front edge (5) to allow the front side edges to cut anterior and posterior surface of the implant.

Abstract: A device for forcibly inserting a surgical implant into a receiving bone (4), by impaction, comprising an impactor (10) which exerts an impact force on the implant and is associated with at least one sensor (12). The sensor (12) measures the deformation of the impactor (10), and provides a measurement signal representing the temporal variation of the deformation during an impact. The sensor (12) is connected to a processing unit (30) configured to calculate, on the basis of the temporal variation of the deformation of the impactor (10) during the impact, an indicator representative of the level of contact between the implant and the receiving bone (4).
