The Swiss OrthoClast® is used for the removal of bone cement during implant revision surgery.

The EMS Swiss OrthoClast® system consists of a pressure regulator/control unit, pneumatic footswitch, handpiece, chisels of various sizes and shapes, a hollow drill and extractor for removal of the cement tip, and the Orthoscope. The Swiss OrthoClast® uses simple pneumatic and ballistic principles to fragment bone cement. A pressure pulse generated by the pressure regulator/control unit causes a moveable projectile in the handpiece to be driven forward to strike the proximal end of the chisel. The impact generates a shock wave along the chisel, which leads to a small, high-speed excursion of the chisel tip. The distal end of the chisel is held in contact with the targeted cement. Repetitive shock waves result in fragmentation of the bone cement. A short tip excursion period followed by a longer rest period prevents the build-up of heat in the fragmentation site. Direct vision into body cavities, such as the femoral cavity, is facilitated using the Orthoscope.

The intended use of the CurvTek TSR System is substantially equivalent to the predicate devices listed in this 510(k) application. The device is to be used to drill holes in bone, except for cranio and maxifacial bones, for soft tissue attachment, or wiring/cabling as in the following techniques: Soft Tissue Repair Techniques (Shoulder, Hip, Elbow, Knee, Limb Salvage, Hand and Wrist, Foot & Ankle, Urological) and Wiring/Cabling Techniques (Cervical Cabling, Lumbar Cabling, Osteotomy of Cervical Spine, Arthrodesis, Lateral Transverse Process, Trauma).

The CurvTek TSR System is a pneumatically powered instrument system consisting of a handpiece, disposable single patient use drill bit cartridges, and 510(k) approved accessories. Accessories include Zimmer® (Hall®) style nitrogen hose and sterilization container system.

The ACL instruments are used for the reconstruction of anterior cruciate ligament with the patellar ligament using the press-fit technique.

The ACL instrument by Boszotta allows fast and standardized removal of the patellar ligament by an optimal arthroscopic press-fit technique. The standardized diameter of the bone plugs allows optimum bone contact and promotes rapid healing.
