Objectives: The treatment of symptomatic unstable os acromiale can be fraught with challenges. It is estimated that between 3-5% the population has an unfused mesoacromion, but only a small fraction those shoulders develop painful, mobile mesoacromion requires treatment. variety concomitant shoulder pathology and overlapping symptoms make diagnosis difficult. Furthermore, there remains no conse...

Os acromiale is a rare anatomical abnormality and treatment is controversial. Our retrospective study analyses the outcome of excision, acromioplasty and bony fusion of the os acromiale when it is associated with a tear of the rotator cuff. After a mean follow-up of 41 months, 33 patients were radiologically and clinically assessed using the Constant score. The surgical procedure was to repair ...

BACKGROUND Trunk lean over the stance limb during gait has been linked to a reduction in the knee adduction moment, which is associated with joint loading. We examined differences in knee adduction moments and frontal plane trunk lean during gait between subjects with knee osteoarthritis and a control group of healthy adults. METHODS Gait analysis was performed on 80 subjects (40 osteoarthrit...

The impingement syndrome’s aetiology is multifactorial. The mechanical factors potentially contributing to this pathology are altered neuromuscular control, decreased force of the rotator cuff and peri-scapular muscles, the acromion’s morphology and posture and stiffness of the posterior capsule (Michener et al., 2003). Amongst these dysfunctions, the authors want to focus on the retraction of ...

The trapezius muscle originates on the occipital bone, nuchal ligament, spinous process of the 7th cervical vertebra (C7) and all of the thoracic vertebrae (Figure 1). It has three parts. The superior portion (descending fibers) terminates on the posterior margin and superior side of the lateral third of the clavicle. The transverse portion (middle fibers) terminates on the medial margin of the...

Subacromial shoulder pain is commonly located to the top and lateral side of the shoulder. It is exaggerated by overhead activity and can be associated with night pain. It is usually associated with full passive range of movement of the glenohumeral joint. The pain originates from the subacromial space of the shoulder, an area made up of the rotator cuff tendons and the subacromial bursa. This ...

Scapular spine stress fractures have been scarcely reported in the literature. Their pathomechanics, clinical course and treatment are not well established. We review 3 cases in 2 patients that were associated with cuff dysfunction. On follow-up, none of these fractures progressed to healing. Two of them needed osteosynthesis and bone grafting, and the third one became a painless non-union. The...
