In the treatment of anterior shoulder instability, there are various conditions in which a sling effect is needed to enhance anterior stability. The traditional Bristow-Latarjet procedure provides a sling effect but destroys or does not purposely protect the coracoacromial (CA) arch, which may result in superior instability. To preserve the CA arch and create a sling to enhance the anterior-inf...

Mesozoic bird fossils from the Pacific Coast of North America are rare, but small numbers are known from the Late Cretaceous aged sediments of Hornby Island, British Columbia. Most are unassociated fragments that offer little information, but additional preparation of a large coracoid has revealed more details of its structure, as well as three associated wing bones. Phylogenetic analysis sugge...

We present a case of failure of acromioclavicular joint (ACJ) reduction that was performed with low-profile, double-metallic button technique (Tightrope; Arthrex Inc). The patient presented with coracoid fracture and loss of reduction within eight weeks of surgery.

Variations on the neuromuscular structures of the upper limb reflect the complex development of that region. Many of them may be important during surgical and/or diagnostic procedures; however, some of them are of academic interest. Here we report a case of six neuromuscular variations in a single upper limb. During routine educational dissection for the undergraduate medical students at the De...

BACKGROUND Appilication of MR imaging to diagnose Adhesive Capsulitis (AC) has previously been described. However, there is insufficient information available for the MRI analysis of AC. This study is to describe and evaluate the pathomorphology of the shoulder in Asian patients with AC compared to healthy volunteers. METHODOLOGY/PRINCIPAL FINDINGS 60 Asian patients with clinically diagnosed ...

Examination revealed minimal swelling over the right shoulder. His shoulder was protected in a sling and he performed limited pendulum exercises for the first two weeks. His range of motion on the right side was significantly decreased, particularly to abduction, external rotation and internal rotation. His supraspinatus was also weak and very painful to strength testing but both anterior and p...

The aim of this study was to identify shape patterns of the shoulder girdle in relation to different functional and environmental behaviours in turtles. The Procrustes method was used to compare the shoulder girdles (scapula and coracoid) of 88 adult extant turtles. The results indicate that four shape patterns can be distinguished. The shoulder girdles of (1) terrestrial (Testudinidae), (2) hi...
