Which tuning fork test evaluates conductive and sensorineural hearing loss in both ears at the same time?. How do you know if your hearing loss is sensorineural or conductive audiogram?.What does conductive hearing loss sound like?.Which action by the nurse is consistent with Weber’s test?.What does it mean when air conduction is greater than bone conduction?. What is tested between conductive and sensorineural hearing loss?.In this way, the lateral drawer test would decrease the number of patients who need additional radiographs at the initial clinic visit and shorten the waiting time for patients with grossly unstable ankle fractures who may otherwise be told to try a period of weight-bearing. Grade II-Obtain a stress radiograph and evaluate for MCS widening at the initial visit.Weight-bearing radiographs may be taken at that later time Grade 0 or I-Patients may safely forego additional stress radiographs at the initial clinic visit and may be asked to follow up after one week of weight-bearing, as tolerated.The lateral drawer test can be regarded as an additional piece of data to help determine the optimal timing of stress radiographs: However, even a sensitivity of 83% is too low to be used as the sole determinant for surgical indications. The lateral drawer test is so quick to perform, it can be seamlessly integrated into the physical examination. No patient demonstrated guarding during the examination that precluded the provider from performing the test. The average pain score was 4.2 before the test and 4.9 after. There was a strong correlation between grade on the lateral drawer test and the extent of MCS widening (ρ=0.82 P<0.005).Ĭompared with the GSV, the lateral drawer test demonstrated a sensitivity of 83%, specificity of 97%, positive predictive value of 96% and negative predictive value of 86%. Resultsģ0 patients (48%) demonstrated an unstable ankle fracture, defined as medial clear space (MCS) ≥5 mm on the GSV. The examining orthopedic surgeons did not view the radiographs until after performing the lateral drawer test. Using a visual analog scale (0–10), patients rated their pain at rest before manipulation and their maximal pain during the maneuver.įor each patient, the team obtained three radiographic views of the non-weight-bearing ankle (anteroposterior, lateral, and mortise) as well as the gravity stress view (GSV), which was used as the "true" test of instability. There were 41 females and 21 males, mean age of 49 (range, 21–85). The researchers prospectively studied 62 adults who presented with an acute isolated Weber B ankle fracture within one week of injury.
