Abstract

By listening carefully to the hammering noises made by the stem being placed into the femur during total hip arthroplasty, intraoperative femoral fractures can be prevented. This method is based on a hammering test that takes use of the fact that sound depends on an object's stability. Typically, engineering uses this method. A system based on this method and software for real-time spectra analysis has been created with continual advancements in order to prevent excessive stem hammering by forecasting the intraoperative fracture risk. The final technical hurdle is choosing a suitable sound gathering tool and creating a small, simple machine. In order to create a useful THA support system, this study examined the kinds of directional microphones appropriate for the sound gathering system. The peak frequencies of the hammering noises were collected and compared using four different types of microphones based on chosen methodologies, and clinical trials were then carried out using the developed system. Plug-in unidirectional microphones are suitable for the unit's compactness and simplicity of use. Nevertheless, no laboratory-level data have been gathered, thus more data gathering is required.
