Animated video reduces pain and anxiety during pin removal in children with supracondylar humerus fractures: a randomized controlled trial.

INTRODUCTION: The aim of this study; is to determine the level of pain and anxiety experienced by pediatric patients with operated humeral supracondylar fractures during pin removal, and to investigate the effectiveness of animated video impressions. MATERIALS AND METHODS: This randomized controlled study included 180 patients aged between 4 and 12 years. The patients were divided into four groups: Group 1-control; Group 2-watched the introductory animation video before the procedure; Group 3-using analgesic before the procedure (ibuprofen 10 mg/kg); Group 4-watched the introductory animation video and used analgesic before the procedure. To assess pain before randomization, before-during-after procedure, and at outpatient clinic controls; the Wong-Baker Pain Scale (WBS), modified CHEOPS (Children's Hospital of Eastern Ontario Pain Scale), and the child's heart rate were used. To assess anxiety; the Children's Anxiety Meter (CAM), The Short State Anxiety Inventory Scale (SAIS), and The Children's Emotion Management Scales (CEMS) were used. RESULTS: While a significant difference was detected between the groups in the tests performed at certain intervals (p < 0.001), no significant difference was detected between Groups 1-3 and Groups 2-4. The Modified CHEOPS and CEMS values obtained during the procedure showed significant variability between the groups (p < 0.001). Similarly, While a significant difference was detected between the groups in the WBS scores measured during the procedure (p < 0.001), it was observed that there was no significant relationship between Groups 1-3 and Groups 2-4 (p = 0.892, p = 0.820). CONCLUSIONS: Watching an introductory animated video before pin removal is an effective method to relieve the anxiety and pain felt in children with supracondylar fractures.

How Reliable Are Digital Radiographs for Evaluating Intra-articular Displacement in Ankle Epiphyseal Fractures: Can Computed Tomography Be Eliminated?

BACKGROUND: The amount of intra-articular displacement of the fracture is the main issue when deciding the treatment method between conservative or surgical means in intra-articular fractures. In this study, we aimed to determine the intraobserver and interobserver reliability of measuring intra-articular displacement and to compare the digital radiographic and computed tomographic (CT) evaluations in distal tibia intra-articular epiphyseal fractures. METHODS: Thirty-seven patients with digital radiography and CT scans were included in the study. Four sets were prepared with these images. Two of four sets were prepared as ankle radiographs, and the other two sets were prepared with CT scan views. Five observers were asked to measure the intra-articular displacement of the fractures in millimeters and also to make a decision between displacement amounts over or under 2 mm. Intraclass correlation coefficient scores were calculated for evaluation of intraobserver reliability, and Fleiss kappa values were calculated for interobserver reliability evaluations. A value greater than 0.75 was accepted as excellent agreement; 0.75 to 0.40 as intermediate to good agreement; and below 0.40 as poor agreement. RESULTS: There were 15 Salter-Harris type 3, 13 Salter-Harris type 4, seven triplanar, and two Tillaux-Chaput fractures. Both intraobserver and interobserver reliabilities were slightly higher for CT scan evaluations. Amounts of displacement were found to be measured higher after CT scan evaluations other than radiographs. After the measurement of joint displacements on CT scans, it was observed that the measurements found below 2 mm on the digital radiograph measurement changed to greater than or equal to 2 mm in 16.4% of the patients. CONCLUSIONS: This study confirmed that digital radiographs cannot replace CT scans for the measurement of intra-articular displacement in ankle epiphyseal fractures.

The influence of anesthesia-body mass index and chronicity of the injury on the reliability of diagnostic tests for anterior cruciate ligament rupture.

This study aimed to analyze the accuracy and interobserver reliability of the four common diagnostic tests for anterior cruciate ligament (ACL) rupture. The effect of anesthesia, chronicity of the injury and patient's body mass index (BMI) on the reliabilities was also assessed. Patients who underwent arthroscopic knee surgery were examined before the surgery and under anesthesia by three observers categorized based on their experience levels. One hundred two patients were evaluated to determine the accuracy of these tests. Sixty-two patients with ACL rupture were further examined to assess the effect of BMI (≤25 kg/m2, or >25 kg/m2) and chronicity (≤4 or >4 weeks) of the injury on reliabilities with using the Fleiss kappa method. The Lachman test performed under anesthesia had the highest sensitivity (100%, 100%, and 96.7%). In contrast, pivot shift and lever sign tests had the lowest sensitivity both in awake (24.2%, 17.7%, 8.1% and 37.1%, 33.8%, 29%) and anesthetized condition (75.8%, 75.8%, 67.7% and 41.9%, 43.5%, 40.3%). Specificities of the tests except pivot shift were negatively affected when performed under anesthesia. The reliability of the anterior drawer test was perfect under anesthesia. The lever sign test had the highest reliability in the awake condition in patients with a BMI of >25 kg/m2. Furthermore, the reliabilities of the anterior drawer, Lachman, and pivot-shift tests in awake condition were found to be increased in patients with a chronic injury. Finally, the examiner's experience is not important for the physical diagnosis of ACL rupture.

Ankle Joint Injuries Accompanying Fifth Metatarsal Base Fractures.

BACKGROUND: Fifth metatarsal base fractures are the most commonly seen fractures of the foot. Ankle sprains occur with inversion and plantarflexion mechanisms, similar to most fifth metatarsal base fractures. We sought to investigate the possible ankle injuries that accompany fifth metatarsal base fractures. METHODS: A hospital's digital database was searched for the International Classification of Diseases, Tenth Revision codes for metatarsal bone fractures (codes S92.30 and S92.35) between January 2015 and January 2018. Thirty-nine patients with fifth metatarsal base fracture who underwent ankle magnetic resonance imaging (MRI) within 14 days of injury were included in the study. The MRI findings were evaluated, and comparisons were performed according to fracture zone, sex, and age. RESULTS: The most common MRI finding was talocrural joint effusion, which was observed in 28 patients (71.8%). Bone marrow edema was observed in 16 patients (41.0%). Chondral injury at the medial dome of talus was observed in three patients (7.7%). Grade 1 ligament sprain was observed in six patients (15.4%): two in the lateral ligament and four in the deltoid ligament. CONCLUSIONS: Although most fifth metatarsal base fractures and ankle sprains occur as a result of a common mechanism, physical examination findings and patients' complaints are very important. Routine MRI should be unnecessary for most patients. If a patient with a fifth metatarsal base fracture has complaints about the ankle joint, one should be aware of bone marrow edema, which was observed in 41.0% of the study population.

Quantitative assessment of changes in lesser trochanter shapes in relation to femoral rotations.

OBJECTIVE: The aim of this study was to evaluate changes in lesser trochanter shapes in relation to femoral rotations and to develop a reference value for the determination of clinically relevant malrotation of the femur. METHODS: Patients who underwent computed tomography angiography between January 2009 and July 2018 were identified based on a review of their institutional medical records. Thereafter, three-dimensional (3D) images of the whole femur for a total of 860 patients were obtained from their tomographic sections. The distance between the lateral outer cortex of the femur and the most medial point of the lesser trochanter with the femur in neutral rotation was measured and set as the reference value. Then, the same distance was measured at 5°, 10°, 15°, and 20° of femoral internal rotation and at 5°, 10°, 15°, 20°, and 25° of femoral external rotation. To avoid magnification errors, the reference values were divided by each measured value at these different rotation angles and then multiplied by 100. RESULTS: The mean distances between the lateral cortex and the most medial point of the lesser trochanter at 5°, 10°, 15°, and 20° of femoral internal rotation were 97%, 93%, 90%, and 88%, respectively, of those measured with the femur in neutral rotation. The same distances at 5°, 10°, 15°, 20°, and 25° of femoral external rotation were 102%, 104%, 106%, 107%, and 108%, respectively, of those measured with the femur in neutral rotation. There was no statistically significant difference between the measured distances in males and females (p>0.05). However, significant differences were observed among each measured distance at different angles of femoral rotation (p<0.01). CONCLUSION: The surgeon should be aware of the possible femoral malrotation if the distance between the lateral cortex of the femur and the most medial point of the lesser trochanter on the operated side is more than 106% or less than 90% of that measured with the femur in neutral rotation on the healthy side. LEVEL OF EVIDENCE: Level IV, Diagnostic study.
