value of ultrasound for stability assessment of isolated lateral malleolar fractures compared to Stress Radiography and arthroscopy
Clinics in Orthopedic Surgery, 2020Co-Authors: Hyong Nyun Kim, Seungmin Jeong, Young Uk ParkAbstract:Background This study was performed to evaluate the value of using ultrasound for stability assessment of isolated lateral malleolar fractures compared to simple X-ray, Stress Radiography, and arthroscopy. Methods This is a prospective cohort study with 25 consecutive patients who underwent an arthroscopic examination and subsequent surgery for isolated lateral malleolar ankle fractures. Before operation, simple and external rotation Stress radiographs were obtained. Ultrasound was performed to assess the medial deltoid ligament prior to operation. Arthroscopic findings were used as reference standards. Sensitivity, specificity, and positive and negative predictability were calculated and compared using receiver operating characteristic (ROC) curve analysis for simple Radiography, Stress Radiography, and ultrasound examination. Results The sensitivity and specificity of ultrasound for tears of the deep deltoid ligament were 94.74% and 66.67%, respectively. But, they were both 100% for complete tears of the ligament. ROC curve analysis showed that the ultrasound examination was significantly more accurate than simple and Stress Radiography. Conclusions Ultrasound could be used to assess the instability of isolated lateral malleolar fractures. Commonly used Stress Radiography appears to overrate the need for operative treatment.

However, both examinations can yield incorrect results and do not reveal the extent of ankle instability. Stress ultrasound has been reported to be a new diagnostic tool for the diagnosis of chronic ankle instability. The purpose of this study was to assess the diagnostic value of Stress ultrasound for chronic ankle instability compared to the manual anterior drawer test, Stress Radiography, magnetic resonance imaging (MRI), and arthroscopy. Twenty-eight consecutive patients who underwent ankle arthroscopy and subsequent modified Brostrom repair for treatment of chronic ankle instability were included. The arthroscopic findings were used as the reference standard. A standardized physical examination (manual anterior drawer test), Stress Radiography, MRI, and Stress ultrasound were performed to assess the anterior talofibular ligament (ATFL) prior to operation. Ultrasound images were taken in the resting position and the maximal anterior drawer position. Grade 3 lateral instability was verified arthroscopically in all 28 cases with a clinical diagnosis (100 %). Twenty-two cases showed grade III instability on the manual anterior drawer test (78.6 %). Twenty-four cases displayed anterior translation exceeding 5 mm on Stress Radiography (86 %), and talar tilt angle exceeded 15° in three cases (11 %). Nineteen cases displayed a partial chronic tear (change in thickness or signal intensity), and nine cases displayed complete tear on MRI (100 %). Lax and wavy ATFL was evident on Stress ultrasound in all cases (100 %). The mean value of the ATFL length was 2.8 ± 0.3 cm for the Stressed condition and 2.1 ± 0.2 cm for the resting condition (p < 0.001). Stress ultrasound may be useful for the diagnosis of chronic ankle instability in addition to the manual anterior drawer test and Stress Radiography. III.

new method of diagnosis for chronic ankle instability comparison of manual anterior drawer test Stress Radiography and Stress ultrasound
Knee Surgery Sports Traumatology Arthroscopy, 2014Co-Authors: Kyung Tai Lee, Young Uk Park, Hyuk Jegal, Jong Won Park, Jung Pil Choi, Jin Su KimAbstract:To diagnose chronic ankle instability, clinicians frequently use manual anterior drawer test and Stress Radiography. However, both exams can yield incorrect results and do not reveal the extent of ankle instability. The use of Stress ultrasound during a manual anterior drawer Stress procedure might enable the diagnosis of chronic ankle instability. Seventy-three patients with chronic ankle pain or laxity after remote ankle sprain were included. The study population included 41 males and 32 females. The mean age of the patients at the time of the operation was 29 years. A standardized physical examination (manual anterior drawer test), Stress Radiography and Stress ultrasonography were performed to assess the anterior talofibular ligament (ATFL). Ultrasound images were taken in the resting position and the maximal anterior drawer position. The statistical significance of Stress ultrasound among the three groups according to manual anterior drawer test and a specific degree (5 mm) of anterior translation of Stress Radiography were analysed. Correlation coefficients between Stress ultrasound, Stress Radiography and manual anterior drawer test were calculated. There was a significant difference for ATFL length (ATFL Stress) and ATFL ratio (ATFL Stress/ATFL resting) among the three groups (both p < 0.001). However, there was no significant difference for anterior translation of Stress Radiography among three groups according to manual anterior drawer test (p = 0.159). There was a significant difference for ATFL length (ATFL Stress) and ATFL ratio between two groups with 5-mm anterior translation of Stress Radiography (p = 0.002 and p = 0.011, respectively). The mean value of grade of manual anterior drawer test between the two groups also differed (p = 0.021). There was a moderately positive linear relationship between Stress ultrasound and manual anterior drawer test. Also, there was a positive linear relationship between Stress ultrasound and Stress Radiography. The results suggest that the value of ATFL length (ATFL Stress) and ATFL ratio of Stress ultrasound could be used for diagnosis of chronic ankle instability in addition to manual anterior drawer test and Stress Radiography.

quantification of anterior translation of the humeral head in the throwing shoulder manual assessment versus Stress Radiography
American Journal of Sports Medicine, 2000Co-Authors: Todd S Ellenbecker, Angelo J Mattalino, Eric Elam, Roger CaplingerAbstract:Clinical evaluation of humeral head translation relies mainly on manual tests to measure laxity in the human shoulder. The purposes of this study were to determine whether side-to-side differences exist in anterior humeral head translation in professional baseball pitchers, to compare manual laxity testing with Stress Radiography for quantifying humeral head translation, and to test intrarater reliability of the manual humeral head translation and Stress Radiography tests. Twenty professional baseball pitchers underwent bilateral manual anterior humeral head translation and Stress radiographic tests. Stress Radiography was performed by imparting a 15-daN anterior load to the shoulder in 90 degrees of abduction with both neutral and 60 degrees of external rotation and recording the glenohumeral joint translation at rest and under Stress in each position. Eight subjects were retested to assess the reliability of these methods. Results showed no significant difference between the dominant and nondominant extremity in the amount of anterior humeral head translation measured manually and with Stress Radiography, nor significant correlation between anterior humeral head translation measured manually and by Stress Radiography. Test-retest reliability was moderate-to-poor for the manual humeral head translation test and moderate for Stress Radiography.

medial elbow joint laxity in professional baseball pitchers a bilateral comparison using Stress Radiography
American Journal of Sports Medicine, 1998Co-Authors: Todd S Ellenbecker, Angelo J Mattalino, Erik A Elam, Roger CaplingerAbstract:Injuries to the ulnar collateral ligament frequently occur in throwing athletes because of large, repetitive valgus Stresses to the elbow during the cocking and acceleration phases of throwing. Identification of injury to this ligament is important in evaluating the throwing elbow. The purpose of this study was to determine whether differences in medial elbow laxity exist between the dominant and nondominant extremities in uninjured baseball pitchers. Forty uninjured professional baseball pitchers were tested bilaterally with a Telos GA-IIE Stress Radiography device. Joint space width between the trochlea of the humerus and the coronoid process of the ulna was measured on anteroposterior radiographs obtained with no Stress applied and with a 15-daN valgus Stress. Results showed significant differences between the medial joint space opening of the dominant and nondominant elbows with no Stress applied. With Stress, the dominant elbow opened 1.20 +/- 0.97 mm, while the nondominant elbow opened 0.88 +/- 0.55 mm. A significantly greater difference in medial joint space opening between the Stressed and unStressed elbows was measured in the dominant elbow compared with the nondominant elbow (0.32 +/- 0.42 mm). This study identifies increased medial elbow laxity in the dominant arm in uninjured pitchers.
