REVIEW
Bin Yuan, Bao-Jian Ge, Bai-Yi Meng
Dislocation of proximal tibiofibular joint(PTFJ) is relatively infrequent in clinic, it can be either isolated or associated with tibia fracture, fibular fracture and ankle injury and so on. Chronic symptomatic PTFJ instability are easily mixed with meniscal tears. It was easily neglected because of the mild clinical presentation and atypical change on radiography. Early diagnosis and treatment are crucial to prevent chronic knee pain and instability. The paper concluded the anatomy, classification, complication, diagnosis, treatment, clinical effect and insufficient of the dislocation of PTFJ, to direct the diagnosis and treatment of proximal tibiofibular joint dislocation in clinical work...

Case summary: A 5-month-old intact female Scottish Fold cat was presented for cardiac evaluation. Careful auscultation detected a slight systolic murmur (Levine I/VI). The findings of electrocardiography, thoracic radiography, non-invasive blood pressure measurements and conventional echocardiographic studies were unremarkable. However, two-dimensional speckle tracking echocardiography revealed abnormalities in myocardial deformations, including decreased early-to-late diastolic strain rate ratios in longitudinal, radial and circumferential directions, and deteriorated segmental systolic longitudinal strain...

Subacromial impingement syndrome results from irritation of the tendons of the rotator cuff muscles in the subacromial space and may manifest as a range of pathologies. However, subacromial impingement is a dynamic condition for which imaging reveals predisposing factors but no pathognomonic indicators. Also, the usual imaging features of subacromial impingement may be seen in symptomatic and asymptomatic patients. Therefore, imaging is able to detect tears and describe the risk factors of impingement but cannot confirm subacromial impingement...

Fractures of the fifth metatarsal base are among the most common fractures of the foot. They are typically caused by indirect violence during sports activities. This region is also a site where stress fractures occur frequently. Diagnosis is based on the patients medical history, clinical examination and imaging methods. The fundamental imaging method is radiography of the foot in three views. MRI is used primarily for early diagnosis of stress fractures. CT examination is beneficial mainly in complex foot injuries, in order to rule out associated fractures...

The study presents an overview of the most common radiography and CT-based classifications of posterior malleolar fractures in ankle fracture-dislocations. Their analysis has shown that posterior malleolar fractures largely vary in size and shape. Evaluation of fractures by plain radiographs is inadequate. A detailed assessment of the fragment shape and course of fracture lines requires CT examination in all three projections, followed by 3D CT reconstructions.Key words: ankle fracture - dislocations trimalleolar fractures posterior malleolar fractures classification...

Abdominal radiography and computed tomography scans are standard tests to diagnose pneumoperitoneum. With the growing availability of point-of-care ultrasound, pneumoperitoneum may be diagnosed in settings without easy access to radiography or computed tomography, such as in overcrowded emergency departments or resource-poor environments. The use of point-of-care ultrasound to diagnose or monitor pneumoperitoneum has been described in adult but not pediatric patients. We present a case of point-of-care ultrasound detection of pneumoperitoneum and monitoring for tension pneumoperitoneum, after failed air enema reduction for intussusception in an infant...

The posterior cruciate ligament (PCL) is the largest and strongest ligament in the human knee, and the primary posterior stabilizer. Recent anatomy and biomechanical studies have provided an improved understanding of PCL function. PCL injuries are typically combined with other ligamentous, meniscal and chondral injuries. Stress radiography has become an important and validated objective measure in surgical decision making and post-operative assessment. Isolated grade I or II PCL injuries can usually be treated non-operatively...
