Objective: To describe the posterior labral lesions and labrocapsular abnormalities of the shoulder on sonoarthrography and to compare these findings with MR arthrography results. Methods: 82 shoulders were initially evaluated with ultrasonography and MRI and then were examined with sonoarthrography and MR arthrography following intraarticular injection of diluted gadolinium solution. The ultrasonography images were prospectively evaluated for the presence of posterior labral tear, sublabral cleft, and posterior capsular abnormalities by two radiologists. The diagnostic accuracy of sonoarthrography in the detection of posterior labral tears and posterior labrocapsular variants was compared with that of MR arthrography. Results: In sonoarthrographic examinations of 82 shoulders, 5 and 6 posterior labral tears were identified by Observer 1 and 2, respectively. Moreover, 6 and 7 posterior sublabral clefts, and 2 and 3 posterior synovial folds were identified by Observer 1 and 2, respectively. All the 82 patients were examined with MR arthrography; however, only 14 patients underwent arthroscopic examination. No significant difference was found among the 82 patients with regard to age, gender, and the prevalence of posterior labral tear, posterior labral cleft, and posterior synovial fold (p > 0.05). Interobserver variability showed substantial agreement between the sonoarthrographic and MR arthrographic results of the posterior labrocapsular structures (κ = 0.71, p < 0.05). Conclusion: Posterior labral tears and posterior synovial folds of the shoulder joint can be evaluated non-invasively by sonoarthrography. Advances in knowledge: Variations and pathologies of posterior labrocapsular structures of the glenohumeral joint are relatively uncommon. Direct (MR) arthrography is the gold-standard imaging modality to evaluate of posterior labrocapsular abnormalities of the glenohumeral joint. Sonoarthrography of the glenohumeral joint may be utilized in clinical practice in patients with contraindications to (MRI).

Synovial Folds

AbstractSynovial plicae are vestigial folds of synovium in a joint, most widely recognized in the knee and also in the elbow and hip joints. The most commonly shared theory on the origin of plicae is that they are the remnants of the membranes that divide the synovial cavitations during normal joint development. Synovial folds do not generally cause any symptoms. However, they can become inflamed, thickened, fibrosed, and also impinged in the joint, leading to mechanical symptoms and chondral damage. This article presents an overview of the embryological origin of plicae, their anatomy, pathologies, and appearances on imaging. We also discuss the lesser known plicae in various other areas.

Background Impaired movement of the cricoarytenoid joint with hoarseness and immobility of the vocal ligament can occur as a consequence of endotracheal intubation. The biomechanics and pathomechanism of cricoarytenoid subluxation have not been demonstrated to date. Methods The present study attempts to simulate the trauma that has been associated with arytenoid cartilage subluxation in intubation trials on 37 unfixed larynges in cadavers from persons aged 25 to 89 years. Larynges were intubated or extubated according to former conceptions of arytenoid subluxation, which assume that the arytenoid tip enters the lumen of the tracheal tube, or that a deflection of the arytenoid occurs during withdrawal of the endotracheal tube with the cuff of the tube only partially deflated. Also, manual attempts were carried out to subluxate the arytenoid cartilage. Subsequently after dissecting the left and right cricoarytenoid joint from each larynx, the morphologic changes induced experimentally were analyzed using gross microscopic and histologic methods. Results Within the scope of the experiment, it proved impossible to produce any subluxation of a cricoarytenoid joint. Histologic analysis revealed injuries of synovial folds, joint-surface impressions of the articular cartilage, and fractures in the area of the subchondral bone in some joints. Conclusions Based on the morphologic results, it was concluded that intubation trauma of the cricoarytenoid joint does not cause subluxation per se, but rather that formation of a hemarthros or fractures of the joint bodies lead to fixation of the joint surfaces in an abnormal position. Subsequent ankylosis may occur.

Up to the present time practically not studied the peculiarities of formation of cartilage inthe various compartments of the shoulder joint in dogs, as well as zones of least resistancejoints in General. Available studies mainly use visual diagnostic methods, without applyingmorphological and morphometric. There is no information about age-related cytomorphologicaltransformations occurring in the joint in normal and pathological conditions. In this regard,the aim of our study was to determine the zone of risk of damage to the shoulder joint in dogs.Studies were conducted on dogs and cadaver material, selected from giant, large and mediumsized breeds. Arthroscopic studies of dogs were performed, as well as light microscopy ofhistological sections of freshly treated samples of joint tissues. As a result of trauma to the jointis transformed physiological synovial folds in sklerozirovanie a pathological form that occurs inGerman shepherd dogs over 5 years of age in 60% of cases. The process of mineralization of thematrix and the appearance of multiple foci of ossification occurs asynchronously in the cartilageof the head of the humerus and the articular cavity of the scapula. Osteoplastic processes in thearea of articulation occur unevenly. Cartilage coating of the articular surface of the shoulderblade is characterized by a more uniform distribution than the articular rotation of the humerushead. The zones of risk of damage to the structures of the shoulder joint in dogs were determined.These include: cranial and medial compartments of the joint, the caudal area of the cartilaginouscoating of the humerus, the caudal area of the articular surface of the scapula cavity. The dataobtained make up for the information about the diagnosis and risk factors in the developmentof shoulder joint pathologies in dogs of large and giant breeds. They should be used in clinicaldiagnosis and surgery of the musculoskeletal system in animals.
