Abstract
A cement restrictor for use in surgical procedures such as total hip replacement, for example, includes a pressure transducer and a transmitter electrically coupled to the pressure transducer. The cement restrictor is configured to be placed at a distal end of a pre-drilled bone canal in a patient's femur, for example, such that the pressure transducer may generate an output signal in response to the presence of bone cement injected into the bone canal and around the cement restrictor. The transmitter is configured to transmit this output pressure signal to an external receiver outside the patient's body.
