Avulsion fracture of the acromion is rare. It is difficult to diagnosis because there is little displacement and it occurs even without direct trauma. We experienced a case without direct trauma that was diagnosed with ultrasonography. A 55-year-old male patient visited our outpatient clinic with shoulder pain resulting from a significant stress at the trapezius muscle during lifting of a steel...

The scapula plays a key role in nearly every aspect of normal shoulder function. Scapular dyskinesis-altered scapular positioning and motion-is found in association with most shoulder injuries. Basic science and clinical research findings have led to the identification of normal three-dimensional scapular kinematics in scapulohumeral rhythm and to abnormal kinematics in shoulder injury, the dev...

CONTEXT AND OBJECTIVE The presence of scapular fracture is believed to be associated with high rates of other injuries and accompanying morbidities. The aim was to study injury patterns and their overall outcomes in patients with scapula fractures. DESIGN AND SETTING Cross-sectional study of trauma patients treated at six general hospitals in Tehran. METHODS One-year trauma records were obt...

We presented a unique case of a high school athlete who suffered from a coracoid process fracture following a collision with an opposing player. This fracture is commonly misdiagnosed as a clavicular fracture or AC joint sprain. Initial radiographic examination may fail to identify the fracture site. Understanding the clinical features of this injury is an important prerequisite to its overall ...

Adhesion of regenerating bone tissue to orthopaedic implants is critical their long-term success. Titanium has excess rigidity, interferes with imaging, and complicates radiation treatment. Poly(ether-ether-ketone) (PEEK) a preferred material, but limited by biological inertness. We show that plasma immersion ion implantation (PIII) imparts osteoadhesion on 3D printed PEEK using in vitro pull-o...
