Oscar Cement Removal Tools

The Orthosonics System for Cemented Arthroplasty Revision (OSCAR) comprehensive revision instrument is designed to facilitate and guide surgeries that involve removing bone cement and other internal prostheses that aid bone function. OSCAR is a lightweight, portable device that uses ultrasonic waves to soften cement and collects the softened cement with its probe. OSCAR also includes a cutting tool that can be used for prosthesis extraction or bone tissue removal. An audiovisual guidance system aids the surgeon in producing highly accurate, safe results.

Components

• The OSCAR system is composed of several individual devices. OSCAR contains an internal probe device, three handsets that can be used to control the probe, a 150 watt light source, and a generator that ensures continuous power to the system in case of power failure. The system also features an LCD display that provides visual and audio information regarding the status of the probe. The probe itself features an ultrasonic wave generator and a receptacle that collects bone cement during the removal procedure.

Cement Removal

• The primary use of the OSCAR system is for the safe removal of bone cement during arthroplasty procedures. The OSCAR system's probe produces an ultrasound wave that causes bone cement to soften to the consistency of putty, leading to much easier removal of the cement from the bone to which it is attached. The probe also contains a receptacle that collects the softened cement as it travels through the surgical zone.

Advantages

• There are several advantages to using the OSCAR system when removing bone cement. OSCAR is very efficient, since the softened putty is removed more easily than when using hard-removal techniques. The OSCAR system also provides the surgeon with continuous audio and visual signals that guide her through the procedure. These improvements help result in maximum cement removal with minimal bone damage.

Recommended Use Sites

• The OSCAR system can be used to remove bone cement that has been affixed to several osseous areas. OSCAR is approved for use with the hips, knees, shoulders and elbows.

Other Uses

• The OSCAR probe can also be used for several other procedures. The audiovisual guidance system can be used in conjunction with a bone cutting attachment to remove cancellous bone, to remove cortical bone, or to extract prostheses. It can also be used to guide the removal of non-cemented acetabular cups.
