The purpose of this manuscript is to review the knowledge of scapular positioning at rest and scapular movement in different anatomic planes in asymptomatic subjects and patients with shoulder impingement syndrome (SIS) and glenohumeral shoulder instability. We reviewed the literature for all biomechanical and kinematic studies using keywords for impingement syndrome, shoulder instability, and ...

BACKGROUND Despite the recognized importance of proper 3-dimensional motion of the scapula in throwers, minimal research has quantified scapular position and orientation in throwing athletes. HYPOTHESIS Throwing athletes exhibit scapular position and orientation differences when compared to nonthrowing control subjects. STUDY DESIGN Descriptive laboratory study. METHODS Scapular position ...

First rib fractures are scarce due to their well-protected anatomic locations. Bilateral first rib fractures accompanying bilateral scapular fractures are very rare, although they may be together with scapular and clavicular fractures. According to our knowledge, no case of bilateral first rib fractures accompanying bilateral scapular fractures has been reported, so we herein discussed the diag...

Scapular winging as a result of isolated serratus anterior dysfunction is a rare pathology. Most cases of long thoracic nerve palsy resolve on their own. However, in recalcitrant cases, its correct diagnosis and proper treatment can ameliorate shoulder dysfunction and restore scapulothoracic motion. This review article addresses the diagnosis and surgical treatment of scapular winging. Specific...

We present a three dimensional (3D) morphometric modelling study of the scapulae of Felidae, with a focus on the correlations between forelimb postures and extracted scapular shape variations. Our shape modelling results indicate that the scapular infraspinous fossa becomes larger and relatively broader along the craniocaudal axis in larger felids. We infer that this enlargement of the scapular...

OBJECTIVE In this study, we aimed to assess whether therapeutic taping for scapular stabilization affected scapulothoracic, glenohumeral, and humerothoracic joint function in children with brachial plexus birth palsy and scapular winging. METHOD Motion capture data were collected with and without therapeutic taping to assist the middle and lower trapezius in seven positions for 26 children. D...

Scapular mobility plays a central role in normal shoulder function, and alterations in scapular mobility have been suggested as a factor in impingement syndrome. We therefore measured the effect of restricted scapular mobility during arm abduction on acromiohumeral and coracohumeral distances. For the control measurements, healthy volunteers (n = 10, all male, age range 25-35 years) underwent m...
