INTRODUCTION: A typical feature of inferior glenoid fractures is a distal fragment separated from the glenoid fossa. In most cases, the inferior glenoid fractures are associated with a fracture of the scapular body. However, there are no detailed studies of inferior glenoid fractures, and only brief mentions can be found in the literature in this respect. MATERIAL AND METHODS: The basic group comprised 42 patients, with the mean age of 48 years, who sustained 42 fractures of the inferior glenoid...

Fracture mapping has been used in the understanding of injury patterns in different bones. To our knowledge, there are no applications of this technique using three-dimensional (3D) morphologic fracture characteristics. Previously, scapula fractures were mapped by transferring information from 3D computed tomography to a two-dimensional (2D) template. Cole et al. determined that 3D Computerized Tomography (CT) scans were more reliable compared to plain radiographs in terms of scapular angulation, translation, and glenopolar angle measurements...

Acute generalized neuropathy as the presenting manifestation of hereditary neuropathy with liability to pressure palsies (HNPP) is rare. We report a 19-year-old Army recruit who exercised regularly for 9 months and presented with 2 weeks of numbness, tingling, and weakness in both upper and lower extremities, starting 2 weeks after influenza vaccination and 1 day after vigorous exercise. Based on acute onset, clinical examination and electrophysiological findings, Guillain-Barre syndrome was diagnosed, and intravenous immunoglobulin was administered with minimal improvement...

Scapular dyskinesis is the term used to describe changes in the positioning or movement of the scapula. Such dysfunction is associated with changes in the activation of the scapular muscles. However, the influence of the axial muscles on the scapular muscles activity of subjects with scapular dyskinesis is unknown. This study aimed to compare the electromyography (EMG) activity of periscapular muscles and its correlation with the external oblique muscle during the execution of push-up performed in different surfaces, in volunteers with and without scapular dyskinesis...

Acromion Marker Cluster (AMC) methods have been shown to accurately track scapula motion during humeral elevation below 90°, however, their accuracy has not been assessed in shoulder girdle motion such as clavicle protraction, retraction, elevation and depression independent of humeral movement. The aim of this study was to examine the reliability and validity of the AMC method to record scapula orientation at end range clavicle protraction, retraction, elevation and depression. The right scapulae of twenty-two female and twenty male asymptomatic volunteers were assessed with an AMC and Scapula Locator (SL) method during end range clavicle protraction, retraction, elevation and depression (without humeral elevation) using an eight-camera 3D movement registration system...

Dermatofibroma, also known as benign fibrous histiocytoma, is a soft-tissue tumour that usually occurs in the mid-adult life and shows a slight female predominance. Giant dermatofibroma, a very rare clinical variant, is characterised by its unusually large size, benign biological behaviour despite its large size and same histopathological characteristics as conventional dermatofibroma. We report a 63-year-old woman who presented with a large tumour on the scapular region which showed histopathological features of benign dermatofibroma...

BACKGROUND: The necessity of sternal precautions for patients following cardiac surgery with median sternotomy has been questioned by clinicians, researchers, and even patients. The primary purpose was to determine if sternal skin deformation during shoulder movements and upper extremity activities is compressive or distractive and if there are any significant differences between the skin deformation at different positions during shoulder movements and upper extremity activities. The secondary purpose was to determine if sternal skin deformation is correlated with scapular stabilizer muscle strength...

The quadrangular space is a space in the axilla bounded by the inferior margin of the teres minor muscle, the superior margin of the teres major muscle, the lateral margin of the long head of the triceps brachii muscle and the surgical neck of the humerus, medially. The axillary nerve (C5-C6) and the posterior circumflex humeral artery and veins pass through this space in order to supply their territories. The subscapularis muscle is situated into the scapular fossa and inserts itself into the lesser tubercle of the humerus, thus helping stabilize the shoulder joint...

INTRODUCTION: Scapular notching after RSA may, in part, be related to a patient's scapular morphology. The purpose of this study was to develop a novel 3D measurement technique to describe infraglenoid tubercle morphometry. We hypothesize that the parameters describing infraglenoid tubercle would be normally distributed and would correlate with individual's demographics and glenoid morphometry. MATERIALS AND METHODS: A group of 110 subjects treated with RSA were evaluated...

The dugong (Dugong dugon, Müller) is an endangered marine mammal species. We examined the relationship between sex, habitat and body length based on the skull and scapular morphology and morphometrics of 81 dugong samples in Thailand. A total of 58 parameters from the skull and scapula (25 from the cranium, 23 from the mandible and 10 from the scapula) as well as tusks were used in this study. Data were analyzed by univariate analysis, followed by discriminant analysis and multivariate linear regression. Here we show, 100% and 98...

The arteriovenous (AV) loop model permits the creation of significant volumes of axially vascularized tissue that represents an alternative to conventional free flaps, circumventing their common limitations. However, such AV-loop-based flaps have never before been examined in standardized animal models with respect to their suitability for reconstruction of critical bone exposing defects. In the course of our preliminary studies, we implemented a novel defect model in rats that provides standardized and critical wound conditions and evaluated whether AV-loop-generated flaps are suitable for free microsurgical transfer and closure of composite defects...

OBJECTIVE: The purpose of this article is to determine the osseous morphology of snapping scapulae on CT images. MATERIALS AND METHODS: Retrospectively, 2D and 3D CT images of the scapulae of 35 patients with snapping scapula were compared with 35 age-matched control group subjects. Two observers analyzed the following parameters: presence of the Luschka tubercle; abnormalities of the bones and periscapular soft tissues; shape, thickness, and length of the superior angle of the scapula; craniocaudal length of the scapula; minimum distance between the scapula and rib cage; depth of the subscapular fossa; and the superomedial angle...

BACKGROUND: Sustained glenohumeral postero-lateral glide administered by a clinician is commonly used in the management of patients with shoulder pain. This technique reduced shoulder muscle activity in asymptomatic individuals, but it is unknown whether a self-administered version of the mobilization leads to similar neuromuscular response. This study compared the effect of sustained shoulder mobilizations (performed by a physiotherapist) with self-administered mobilization (with a belt) on activity levels of scapular and glenohumeral shoulder muscles...

BACKGROUND: Total shoulder arthroplasty (TSA) in cases with posterior wear can be addressed by eccentric reaming of the anterior glenoid or by augmenting the posterior glenoid with bone grafting or augmented glenoid implants. We report the results of TSA with posterior glenoid bone grafting (PGBG) with humeral head autograft in patients with shoulder osteoarthritis and severe posterior glenoid wear. METHODS: A retrospective review of cases from 2004 to 2014 revealed 34 patients...

BACKGROUND: Short malunion of the clavicle after fracture can change scapular kinematics and alter clinical outcome. However, the effects of malunion on kinematics and outcomes remains poorly understood because there have been no in vivo studies measuring changes during active motion with malunion. This study aimed to measure and to compare in vivo 3-dimensional (3D) scapular kinematics between normal shoulders and shoulders with short malunion using 3D-2-dimensional model image registration techniques...
