![]() Conclusion: The tuning fork test is not sensitive enough to rule out a stress fracture on the basis of a negative test. The positive and negative likelihood ratios with 95 confidence intervals were 2.33 (1.17-4.60) and 0.34 (0.16-0.71), respectively. However, in a setting in which there is a moderate to high pretest likelihood of stress fractures, such as military installations with new basic training recruits, it may be reasonable to avoid the cost and delays associated with nuclear imaging by instituting treatment for tibial stress fractures without obtaining a bone scan when the TFT is positive. The positive and negative predictive values were 77 and 63, respectively. ![]() It seems like a reasonable proposition, and if it really. When the tuning fork is struck, then held in contact with the bone, high-frequency vibrations travel into the bone, causing sharp pain if a stress fracture existsor so the logic goes. ![]() Depending on the specific tuning fork, the PPV of stress fractures compared with MRI and bone scan were 72.2 to 90, and 66.6 to 85.7, respectively. Conclusion: The tuning fork test is not sensitive enough to rule out a stress fracture on the basis of a negative test. It’s used as an in-the-moment diagnostic tool to determine whether a runner has a stress fracture. The tuning fork technique in this study produced a mixed range of specificity and sensitivity, which does not match MRI capability. The positive and negative likelihood ratios with 95% confidence intervals were 2.33 (1.17-4.60) and 0.34 (0.16-0.71), respectively. The positive and negative predictive values were 77 and 63%, respectively. Results: The sensitivity and specificity of the tuning fork test were 75 and 67%, respectively. All patients also underwent a bilateral lower-extremity bone scan. Based on these results, 75 to 92 of evaluations using tuning-fork tests completed on similar populations will accurately detect the presence of a fracture, whereas 18 to 94 of evaluations using tuning-fork tests will accurately detect the absence of a fracture. If the patient reported a marked exacerbation or reproduction of shin pain in a localized area of the tibia, the TFT was considered positive. The TFT was performed by applying a 128-Hz tuning fork to the anterior surface of the bared tibia. Made of aluminum alloy and designed to meet medical requirements, the frequency of this tuning fork is designed for use with vibration and bone fracture tests. Methods: Fifty-two patients with a history and physical examination suggestive of tibial stress fracture underwent a TFT followed by a bone scan. Purpose: To compare the performance of the tuning fork test (TFT) with nuclear scintigraphy for the identification of tibial stress fractures.
