Shoulder lesions and body condition of sows at weaning have both environmental and genetic causes. The traits can be scored at farm-level, and following recording, the traits can be included in the breeding goal and directional selection can be applied. However, to further increase the genetic progress of these traits, it is advantageous to develop indicator traits on the selection candidates (test boars or gilts, not yet exhibiting the phenotype themselves). It has previously been suggested that the scapula morphology and the spine of scapula might be a key factor for the sow to develop shoulder lesions...

Postmortem computed tomography (CT) has been extensively used in the last decade for identification purposes and in various anthropologic studies. Postmortem CT measurements of scapulae, analyzed using logistic discriminant function developed in this study, showed 94.5% accuracy in estimating sex. Data analyzed using the Dabbs and Moore-Jansen (2010) discriminant function and the discriminant function generated in this study provided nearly identical results with disagreement in only one case. Height and weight were not statically significant in sex prediction...

BACKGROUND: Operative management of scapular body fractures, when indicated, typically involves extensive exposure through a posterior approach. We present our experience with a deltoid preserving approach that allows excellent exposure of the fracture lines for reduction and fixation while minimizing muscle detachment and overall tissue trauma. TECHNIQUE: Exposure of the scapula was obtained through a posterior incision. The posterior deltoid was exposed and retracted superiorly while the arm was abducted in accordance with Brodsky et al...

Winged scapula is caused by paralysis of the serratus anterior or trapezius muscles due to damage to the long thoracic or accessory nerves, resulting in loss of strength and range of motion of the shoulder. Because this nerve damage can happen in a variety of ways, initial diagnosis may be overlooked. This paper discusses the anatomical structures involved in several variations of winged scapula, the pathogenesis of winged scapula, and several historical and contemporary surgical procedures used to treat this condition...

Aetosauria is a clade of heavily armored, quadrupedal omnivorous to herbivorous archosaurs known from the Late Triassic across what was the supercontinent of Pangea. Their abundance in many deposits relative to the paucity of other Triassic herbivores indicates that they were key components of Late Triassic ecosystems. However, their evolutionary relationships remain contentious due, in large part, to their extensive dermal armor, which often obstructs observation of internal skeletal anatomy and limits access to potentially informative characters...

BACKGROUND: Evaluation of scapular dyskinesis is of clinical interest because it is believed to be associated with pathologies of the shoulder. This study investigated the feasibility of plain-film radiography in evaluating scapular dyskinesis. METHODS: Subjects with unilateral disorders of the shoulder (n = 186) who underwent plain-film radiography of bilateral scapulae were divided into 4 categories of scapular dyskinesis patterns according to the Kibler classification and analyzed...

BACKGROUND: The purpose of this study is to analyze the 3-dimensional scapular dyskinesis and the kinematics of a hook plate relative to the acromion after hook-plated acromioclavicular dislocation in vivo. Reported complications of acromioclavicular reduction using a hook plate include subacromial erosion and impingement. However, there are few reports of the 3-dimensional kinematics of the hook and scapula after the aforementioned surgical procedure. METHODS: We studied 15 cases of acromioclavicular dislocation treated with a hook plate and 15 contralateral normal shoulders using computed tomography in the neutral and full forward flexion positions...

INTRODUCTION: The aim of this study is to describe the anatomy of fractures of the inferior angle and the adjacent part of the scapular body, based on 3D CT reconstructions. METHOD: In a series of 375 scapular fractures, we identified a total of 20 fractures of the inferior angle of the scapular body (13 men, 7 women), with a mean patient age of 50 years (range 3373). In all fractures, 3D CT reconstructions were obtained, allowing an objective evaluation of the fracture pattern with a focus on the size and shape of the inferior angle fragment, propagation of the fracture line to the lateral and medial borders of the infraspinous part of the scapular body, fragment displacement and any additional fracture of the ipsilateral scapula and the shoulder girdle...

Adult brachial plexus injuries frequently lead to significant and permanent physical disabilities. Investigating the mechanism of the injury using biomechanical approaches may lead to further knowledge with regard to preventing brachial plexus injuries. However, there are no reports of biomechanical studies of brachial plexus injuries till date. Therefore, the present study used a complex three-dimensional finite element model (3D-FEM) of the brachial plexus to analyze the mechanism of brachial plexus injury and to assess the validity of the model...

Spinal accessory nerve grafting requires identification of both nerve stumps in the scar tissue, which is sometimes difficult. We propose a direct nerve transfer using a fascicle from the posterior division of the upper trunk. We retrospectively reviewed 11 patients with trapezius palsy due to an iatrogenic injury of the spinal accessory nerve in nine cases. The mean age was 38 years (range 21-59). Preoperatively, patients showed shoulder weakness and limited range of motion. At a mean follow-up of 25 months, active shoulder abduction improvement averaged 57°...

Injuries of the supra-aortic trunk after blunt chest trauma are rare. This is a case report of a blunt traumatic lesion of the innominate artery (IA) origin that exhibited aortic arch involvement with a focus on imaging and treatment. A 41-year-old fisherman presented an IA injury secondary to a high-impact blunt chest trauma. Upon physical examination, vital signs were stable and upper extremity pulses were present. In addition to several bone fractures (costal ribs, clavicle, scapula, temporal, maxillary, and sphenoid), computed tomography angiography revealed dissection/pseudoaneurysm of the IA sparing the bifurcation...

Fractures of the scapular body that extend to involve the neck and glenoid articular surface with a large gap pose a significant problem for surgical exposure. Several surgical approaches for scapula fixation have been described, but all give limited exposure to the entire scapular body, neck and articular surface. Here, we describe our 'Reverse Judet' technique, with cadaveric dissections and discuss a clinical case. We believe this approach gives a wide exposure of the infraspinous scapular body, neck and glenoid articular surface while keeping away from vital neural structures...

The triceps brachii muscle occupies the posterior compartment of the arm in humans and has three heads. The lateral and medial heads originate from the humerus and the long head arises from the infraglenoid tubercle of the scapula. All heads form a common tendon that inserts onto the olecranon and the deep antebrachial fascia on each side of it. Each head receives its own motor branch, which all are thought to originate from the radial nerve. However, several studies reported that the motor branch of the long head of the triceps (LHT) arises from the axillary nerve or the posterior cord...

Background: Chiari malformation type II (CM-II) is mainly characterized by elongation and descent of the cerebellum through the foramen magnum into the spinal canal. Moreover, CM-II is uniquely associated with myelomeningocele. Sprengel's deformity refers to the malposition of the scapula, i.e. scapular elevation which is sometimes accompanied with scapula dysplasia. Although few familial cases of CM-II and Sprengel's deformity have been previously reported, both of these defects are considered to be sporadic, thus the exact etiology and causative genes have largely remained unknown...
