The shoulder is the most frequently dislocated joint in the body due to a larger range of motion and a small area of articulation between the humeral and glenoid surfaces. Traumatic shoulder dislocations, especially those associated with injury to the labroligamentous or bony stabilizers of the joint, lead to further reduction of articular surface contact with resultant glenohumeral instability and recurrent shoulder dislocations. Imaging plays an increasingly important role in the preoperative evaluation of patients with traumatic shoulder instability by evaluating glenohumeral bone loss (uni- or bipolar), assessing soft tissue injuries and identifying patients at risk of postoperative recurrence...

PURPOSE: The shoulder girdle is a complex system, comprised by a kinematic chain and stabilizers. Due to the delicate equilibrium and synchronism between mobility and stability, high external loads may compromise its physiology, increasing the risk of injuries. Thus, this study intends to fully characterize the effects of a rugby tackle on the shoulder's anatomy and physiology. METHODS: For the experimental procedures, a matrix of pressure sensors was used, based on the Teckscan® pressure in-soles, force plates, an isokinetic dynamometer and sEMG (surface electromyography)...

Background: The treatment of diaphyseal forearm fractures using open reduction and plate fixation is generally accepted as the best choice in many studies. However, periosteal stripping, haematoma evacuation may result in delayed union, nonunion and infection. Refracture after plate removal is another concern. To overcome these problems intramedullary nails (IM) with different designs have been used with various outcomes. However previous IM nails have some shortcomings such is rotational instability and interlocking difficulties...

The Latarjet procedure is a complex and difficult operation when performed both with an open approach and arthroscopically. The difficulties come from the fact that it is a combined intra- and extra-articular procedure, and that working close to the brachial plexus may be frightening for surgeons. Because of the high complication and reoperation rates reported in the literature, this procedure is, at the moment, rejected by a large part of the orthopaedic community, specifically in North America. The Chinese experience shows, after the European one, that arthroscopic Latarjet is an efficient and irreplaceable option for the treatment of recurrent anterior shoulder instability in the context of capsular and/or glenoid deficiency...

Arthroscopic Latarjet procedure has shown satisfactory clinical outcomes in the treatment of anteroinferior shoulder instability. Although as of today there is no proven advantage of the arthroscopic procedure over an open one, it is too early to give up. At the same time, crucial to understand the causes of failure, to find the solutions to every single difficulty to simplify this surgery and to make it as accessible as possible.

Using a switching stick from the posterior portal is a frequently employed method of identifying the location for the subscapularis split for a shoulder arthroscopic Latarjet. However, in a recent cadaveric study, in none of the 20 specimens studied did this technique result in the split being placed in the preferred position-the junction of the superior two-thirds and the inferior one-third of the subscapularis. As a result, if the position of the coracoid graft is too superior, the anteroinferior extension of the glenoid arc and the vector of the conjoined sling may be suboptimal and fail to restrain humeral head translation...

Many radiologists are familiar with the preoperative imaging assessment of patients with labral tears, rotator cuff abnormalities, and end-stage arthritis, as well as the subsequent primary reconstructions and repairs commonly encountered in routine clinical management. However, the second-line surgical procedures and augmentation procedures performed for refractory or recurrent shoulder instability and the extra-articular surgical procedures of the shoulder girdle may challenge even the most experienced musculoskeletal radiologist...

REVIEW
L Nové-Josserand, P Clavert
Glenoid exposure is agreed to be a difficult step, but is also a key step in total shoulder arthroplasty, both anatomic and reverse. It conditions unhindered use of the ancillary instrumentation and thus correct glenoid component positioning. The main stages comprise arthrotomy, by opening the rotator cuff, humeral head cut, and inferior glenohumeral release, enabling shifting of the humerus and good exposure of the glenoid cavity. The two main approaches are deltopectoral and anterosuperior transdeltoid. Using the deltopectoral approach, arthrotomy is performed through the subscapularis muscle, by various techniques...
