![]() ![]() After the test, radiographs were taken and interpreted by the attending orthopaedic physician to confirm or rule out the presence of a fracture. It has been suggested that tuning forks and therapeutic ultrasound are diagnostically accurate in identifying stress fractures. Diminished or absent sound from the injured limb as compared with the uninjured limb constituted a positive result. Three trials were performed on each participant, one each with tuning forks of different vibration frequencies (128, 256, and 512 Hz). For example, if the fibula was the injured bone, the vibrating tuning fork was placed on the distal tip of the lateral malleolus and the stethoscope's conical bell was placed on the fibular head ( Figure). tuning Fork testing The tuning fork test consisted of placing a vibrating tuning fork on the skin directly above the point of max-imal bone tenderness for 10 seconds. I listened for a clear tone created by the tuning fork in the uninjured bone and compared it with the sound arising from the injured bone. I then listened to the sound arising from the bone via the stethoscope for approximately 6 to 8 seconds. I struck the tuning fork against a rubber pad and then placed the vibrating tuning fork on the bone distal to the injury site. The tuning fork was placed on the bone distal to the suspected fracture, and the stethoscope's conical bell was placed proximal to the injury site on the same bone. The test was performed on the uninjured limb first. sensitivity, specificity, sound transmission Lesho EP. In this case, I will place the stethoscope on the head of the fibula. Despite the lack of strong evidence for diagnosing all fractures, tuning-fork tests may be appropriate in rural and remote settings in which access to the gold standards for diagnosis of fractures is limited. ![]() The procedure was conducted as described by Misurya et al, 6 except that the conical bell of a stethoscope was used instead of a pediatric stethoscope. The tuning fork will be placed distal to the suspected fracture. There is no time limit and you can attempt the quiz as many times as you need. The author administered the tuning fork test to all participants. You must answer each of the ten questions correctly to complete the module. ![]()
