SONIC DIAGNOSIS OF BONE FRACTURE HEALING - PRELIMINARY-STUDY

[摘要] The definition of bone fracture healing onset, progress and extent is a difficult clinical diagnosis. Available criteria of manual stability, X-ray appearance, symptomatic pain and passage of time are valuable, but subjective in nature. This study explores the transmission and comparative measurement of stress wave disturbances across a fracture site as a technique of quantifying the union state. Results from laboratory animal [dog] experimentation and subsequent clinical usage indicate a potentially valuable method was developed.
