Herein, an awkward case of globe perforation with a bullet-entering from the right posterior scapular region and leaving the body from the right orbit through the eye - is reported. Route of the bullet could be devastating - as it passed through the neck and the maxillofacial region-however by chance no vital damage occurred. Its path was assessed by plain radiography and computed tomography scans. Sometimes prediction of the trajectory is very difficult without additional radiological investigations. Especially, in the case of any high velocity projectile wounding, physician must be aware of the fact that the bullet's course will not be a linear but most probably a complicated one...

BACKGROUND: In a previous biomechanical study, eccentric glenospheres with more inferior position of the center of rotation were shown to improve range of motion and reduce the incidence of scapular notching after reverse total shoulder arthroplasty (RSA). The purpose of this study was to compare the clinical and radiological results of RSA using an eccentric glenosphere to those using a concentric glenosphere and to determine the usefulness of the eccentric glenosphere. METHODS: From 2009 to 2015, we performed a retrospective review of 20 consecutive patients who underwent RSA using a deltopectoral approach...

Aneurysmal Bone Cyst (ABC) is a rare benign tumour, usually affecting early age group and at the metaphysis of long bones. Scapular ABC's are even more rare, especially successfully treated cases. Standard treatment methods like curettage have high recurrence rates hence, adjuvant therapy may be required to avoid recurrence. Polidocanol sclerotherapy is becoming popular because of its safety and efficacy and is being tried successfully for both active as well as aggressive primary ABC of size 3-5cm. We used the same principle in a large secondary ABC of the scapula, which to the best of our knowledge has not been yet reported...

Introduction. Intramuscular myxoma is a rare benign primitive tumor of the mesenchyme founded at the skeletal muscle level; it presents itself like an unpainful, slow-growing mass. Myxomas with bone lysis are even more rare; only 7 cases have been reported in the English literature, but never at the shoulder level. Case Presentation. We describe an 83-year-old patient with a growing mass in the deltoid muscle with unique scapular lysis, without any symptom. Magnetic resonance imaging (MRI) and a biopsy were performed and the diagnosis of intramuscular myxoma has been retained...

BACKGROUND: Preoperative planning with the aid of imaging methods is a principal factor in successful surgery on the shoulder. This work aims to evaluate the variability of glenoid version, spiralling twist and scapular inclination in relation to the frontal axis. Studies focusing on measuring the variability of scapular inclination in the standardised rest position are lacking in the literature. METHODS: We evaluated 104 CT scans of the shoulder. We measured the glenoid version with respect to the scapular axis at three levels...

BACKGROUND: Placement of the glenoid baseplate is of paramount importance for the outcome of anatomical and reverse total shoulder arthroplasty. However, the database around glenoid size is poor, particularly regarding small scapulae, for example, in women and smaller individuals, and is derived from different methodological approaches. In this multimodality cadaver study, we systematically examined the glenoid using morphological and 3D-CT measurements. METHODS: Measurements of the glenoid and drill hole tunnel length for superior baseplate screw placement were recorded to define size of the glenoid and the distance to the scapular notch on cadaveric specimens...

Glenoid hypoplasia, also known as glenoid dysplasia and dysplasia of the scapular neck, is a failure of ossification of the posteroinferior two-thirds of the glenoid. Once thought to be a rare condition, more recent studies have shown that the incidence of glenoid hypoplasia ranges from 18% to 35%. This case report and literature review highlights the typical clinical presentation, the radiologic findings, and the management options for patients with glenoid hypoplasia.

OBJECTIVE: Elastofibroma dorsi (ED) is a rare, benign, soft tissue tumor typically located between inferior corner of scapula and posterior chest wall causing mass, scapular snapping, and pain. When classic symptoms and localization are present, it is diagnosed without biopsy and treated with marginal resection. This study retrospectively analyzed patients operated on for ED to evaluate presenting symptoms, tumor size, complications, and clinical results, and to suggest optimal treatments...

Chronic acromioclavicular (AC) instability is a rare posttraumatic shoulder condition that can lead to undesirable symptoms like persistent pain, muscle fatigue, loss of strength, or even scapular dyskinesis. It is well known that in these cases the superior functional results depend on the restoration of the anatomy and stability of the AC joint in both vertical and horizontal planes. Considering the ligaments degeneration and atrophy in chronic AC joint dislocations, we present an arthroscopic-assisted reconstruction of both the coracoclavicular and AC ligaments using autograft augmentation...

HYPOTHESIS: The objective of the study was to evaluate the development of scapular notching in reverse shoulder arthroplasty by comparing larger glenospheres (42 mm) with smaller glenospheres (38 mm). METHODS: This was a prospective randomized study of 81 patients who had undergone reverse shoulder arthroplasty with a 2-year follow-up. Patients were randomized to receive either a 42-mm glenosphere (38 patients) or a 38-mm glenosphere (43 patients). Scapular notching development was assessed with an anteroposterior radiograph at the end of the follow-up...

Anatomic variations of axillary artery branches are commonly encountered during radiological investigation and surgical operations. Their existence can confuse interpretation of radiological results and lead to undesired complications during surgery. In this report authors describe a rare case of a subscapular arterial trunk that gave origin to thoracodorsal, circumflex scapular, posterior humeral circumflex, and lateral thoracic artery. Such a variation might cause undesired sequelae during trauma management and a variety of common flap harvesting operations including latissimus dorsi, scapular and parascapular flaps...

The coracoid process is a hook-shaped bone structure projecting anterolaterally from the superior aspect of the scapular neck. Surgeons often refer to the coracoid process as the "lighthouse of the shoulder" given its proximity to major neurovascular structures such as the brachial plexus and the axillary artery and vein, its role in guiding surgical approaches, and its utility as a landmark for other important structures in the shoulder. The coracoid also serves as a critical anchor for many tendinous and ligamentous attachments...

BACKGROUND: Subacromial pain syndrome (SAPS) and scapular dyskinesis are closely associated, but the role of pain is unknown. We hypothesized that pain results in asymmetrical scapular kinematics, and we expected more symmetrical kinematics after infiltration of subacromial anaesthetics. OBJECTIVE: To investigate the effect of subacromial anaesthetics on scapular kinematics in patients with SAPS. DESIGN: Observational cohort study. METHODS: We evaluated shoulder kinematics in 34 patients clinically and radiologically (magnetic resonance arthrography) identified with unilateral SAPS using three-dimensional electromagnetic motion analysis (Flock of Birds)...

PURPOSE: Little scientific evidence on the clinical and radiological outcome after stemless reverse shoulder arthroplasty (RSA) exists. The hypothesis of this study was that stemless RSA has an inferior outcome compared to RSA with stem. METHODS: All cases of cuff-arthropathy fullfilling strict selection criteria (selection rate 18.4 %) were treated with stemless RSA between 2009 and 2013. Twenty nine of 37 cases (78.4 %) were clinically and radiologically examined by an independent observer...

BACKGROUND: An extrapleural hematoma (EH) is an uncommon and potentially life-threatening condition defined as the accumulation of blood in the extrapleural space between the parietal pleura and the endothoracic fascia. EH usually occurs after blunt thoracic trauma causing fractures of the sternum and ribs, which can tear the intercostal or internal mammary vessels. Typical radiological findings of EH are a biconvex opacity on the involved hemithorax and the so-called displaced "extrapleural fat sign...

INTRODUCTION: Complex 4-part fractures of the proximal humerus are one of the most difficult fractures to manage. For several years, reverse total arthroplasty (RSA) has been proposed as an alternative to hemiarthroplasty (HA) when internal fixation is insufficient. The goal of this study was to compare the short and intermediate term results of these 2 different types of arthroplasty. MATERIALS AND METHODS: In a retrospective, multicenter study, 57 HA and 41 RSA were reviewed after a follow-up of at least 2 years...

The dorsal scapular artery (DSA) can be either a direct branch of the subclavian artery (SCA), or a branch of the transverse cervical artery (TCA). In mandibular reconstruction, when a free flap is contraindicated a pedicled scapular flap has been described vascularized by the DSA. During the dissection of this flap, there is a risk of lesion of the TCA, which could be fatal to the flap if the DCA is a branch of the TCA. To evaluate the frequency of this anatomic situation, a dissection and radiologic study has been performed...

Fibrodysplasia Ossificans Progressiva (FOP) is a rare autosomal dominant disorder characterized by postnatal progressive heterotopic ossification of connective tissue and congenital malformation of big toes. We report a 3-year male toddler with clinical and radiological features of FOP. He was born with bilateral hallux valgus and at the age of 3 years presented with hard swellings over back, scapular region and forehead that were initially inflammatory and then became bony hard. There is also tilting of neck towards the left due to calcification in neck region...
