INTRODUCTION Osteochondroma or exostosis is most common benign bone tumors. They are usually seen in the metaphyses of long bones with more than 35% of cases affecting the bone around the knee and are seldom found in flat bones like scapula. When present in scapula, they may cause abnormal scapulothoracic movements leading to pain, snapping, and pseudowinging of scapula. CASE REPORT We descri...

Shoulder kinematics, including scapular rotation relative to the trunk and humeral rotation relative to the scapula, were examined during humeral elevation in three vertical planes via video analysis of intracortical pins. Helical axis parameters provided an easily interpretable description of shoulder motion not subject to the limitations associated with Cardan/Euler angles. Between 30 and 150...

The clavicle, proximal humerus and the scapula together form the shoulder joint. The clavicle also forms the bony connection between the upper limb and the thorax. It articulates with the acromion process of the scapula laterally, at the acromioclavicular joint, and the manubrium of the sternum medially, at the sternoclavicular joint. Ligaments connect the coracoid process of the scapula to the...

We use the acronym SICK to refer to the findings one sees in this syndrome (Scapular malposition, Inferior medial border prominence, Coracoid pain and malposition, and dysKinesis of scapular movement). This recently recognized overuse muscular fatigue syndrome is yet another cause of shoulder pain in the throwing athlete who presents with dead arm complaints.1 The hallmark feature of this syndr...

Anterior shoulder dislocations are commonly associated with humeral greater tuberosity fractures (w16% of cases), which include Hill-Sachs lesions. The second most common fracture associated with an anterior shoulder dislocation is a fracture of the anterior glenoid (i.e., bony Bankart lesion). By comparison, a coracoid fracture occurring in association with an anterior shoulder dislocation is ...

Scapula winging is an uncommon condition but one which may be underdiagnosed. Four patients with scapula winging referred to a sports injury clinic are presented. None of the patients was aware of any trauma and a traction injury to the long thoracic nerve is proposed as the aetiology of this condition. These case reports emphasize the importance of excluding winging of the scapula in patients ...

Adult large-bodied theropods are often found with numerous pathologies. A large, almost complete, probably adult Allosaurus specimen from the Howe Stephens Quarry, Morrison Formation (Late Kimmeridgian-Early Tithonian), Wyoming, exhibits multiple pathologies. Pathologic bones include the left dentary, two cervical vertebrae, one cervical and several dorsal ribs, the left scapula, the left humer...
