BACKGROUND: An increasing number of parameters measured on anteroposterior radiographs are used for the evaluation of the bony geometry of the scapula. Inhomogeneous acquisition of images is common because of the lack of standardization in radiographic positioning. Images with malrotation around the horizontal axis of the scapula are particularly frequent. We hypothesized that malrotated images would result in large variations in measured radiographic parameters and that image standardization using qualitative and semiquantitative "omometric" criteria would decrease these variations in measurements...

BACKGROUND: No clear trend has emerged from the literature regarding three-dimensional (3D) translations of the humerus relative to the scapula in shoulders with rotator cuff tears (RCTs). The purpose of this study was to evaluate the kinematics of RCT shoulders using 3D-to-two-dimensional (2D) model-to-image registration techniques. METHODS: Dynamic glenohumeral kinematics during scapular plane abduction and axial rotation were analyzed in 11 RCT patients and 10 healthy control subjects...

BACKGROUND: Anterior shoulder dislocations in young patients are associated with high rates of recurrent instability. Although some surgeons advocate for surgical stabilization after a single dislocation event in this population, there is sparse research evaluating surgical treatment for first-time dislocators. METHODS: Patients undergoing surgical stabilization for anterior shoulder instability were prospectively enrolled at multiple institutions from 2015-2017 and stratified by number of dislocations before surgery...

BACKGROUND: Degenerative rotator cuff tears (RCTs) are generally thought to originate at the anterior margin of the supraspinatus tendon. However, a recent ultrasonography study suggested that they might originate more posteriorly than originally thought, perhaps even from the isolated infraspinatus (ISP) tendon, and propagate toward the anterior supraspinatus. Hypothesis/Purpose: It was hypothesized that this finding could be reproduced with magnetic resonance imaging (MRI). The purpose was to determine the most common location of degenerative RCTs by using 3-dimensional multiplanar MRI reconstruction...

Ultrasound elastography (UE) is a new ultrasound-based imaging technique that provides information about elasticity and stiffness of tissues. This cross-sectional study aimed to identify the diagnostic importance of UE in supraspinatus impingement syndrome. Forty-one subjects, aged 38-70 years, were included in the study. UE was used to determine the elasticity of the supraspinatus muscle. The strain ratio was calculated as the evaluation criteria to measure the elasticity of the muscle. High strain ratio indicated low elasticity...

We developed a functional digital radiography system that provides physiological and functional information of the chest and/or joints using an X-ray flat-panel detector (FPD) system. During chest examination, sequential chest radiographs are taken from inspiration to expiration in order to analyze diaphragmatic movements. Pixel value changes in localized areas of the lung are then assessed to analyze ventilation and circulation. For limb joints, such as the wrist, shoulder, and knee, sequential radiographs during flexion and extension or rotational movement are considered, and movement angles are analyzed...

Jeremy M Burnham, James P Bradley
Shoulder instability is a common problem in contact sports such as the National Football League. Although many elite level football athletes will have shoulder magnetic resonance imaging (MRI) findings consistent with labral tearing on MRI, these imaging findings are not always correlated with symptomatic instability or functional limitations. It is crucial in all patients, not just National Football League athletes, to treat the patient, and not the MRI.

BACKGROUND: Preoperative computed tomography (CT) measurements of glenoid version and inclination are recommended for planning glenoid implantation in shoulder arthroplasty. However, current manual or semi-automated 2-dimensional (2D) and 3-dimensional (3D) methods are user-dependent and time-consuming. We assessed whether the use of a 3D automated method is accurate and reliable to measure glenoid version and inclination in osteoarthritic shoulders. METHODS: CT scans of osteoarthritic shoulders of 60 patients scheduled for shoulder arthroplasty were obtained...

The present study describes the synthesis of carbon dots (CDs) using a non-essential amino acid, asparagine as a precursor. The HR-TEM image shows that the size of the prepared CDs was 2.9±0.2nm with a spherical morphology. The UV-visible spectrum of CDs exhibits a major band at 307nm along with a shoulder band around 207nm corresponding to n-π* and π-π* transitions, respectively. Further, the CDs show emission maximum at 441nm when excited at 348nm. The synthesized CDs were then exploited for the determination of rutin by spectrofluorimetry based on the decrease in emission intensity at 441nm...

A 15-year-old baseball pitcher presented to physical therapy with a 1-week history of acute right shoulder pain experienced during the acceleration phase of throwing. The week after physical therapy evaluation, the patient returned with radiographs and magnetic resonance imaging results that revealed lateral physeal widening with adjacent edema. Additionally, a nondisplaced labral tear was noted. In this case, imaging was necessary for an accurate diagnosis of lateral physeal widening, commonly referred to as "Little League shoulder...

Our retrospective study of burn patients presents a three-step treatment of heterotopic ossification: excision surgery, early rehabilitation, and analgesia. We included patients admitted to the department for treatment of postburn heterotopic ossification between January 1, 1979, and September 30, 2015. The mean age at the time of the burn was 43.3 years. Men accounted for the majority of burn patients who developed an osteoma (70.8%). The mean total skin area burned was 38.4%. No osteoma justifying surgery was found for any patient with a total burned skin area less than 19%...

INTRODUCTION: Tumoral calcinosis is a rare benign disease, defined by the presence of calcified deposits in periarticular tissues. It can be hereditary or secondary at chronic renal failure at the stage of dialysis. This work illustrates the contribution of single-photon emission computed tomography (SPECT/CT) in the diagnosis and management of tumoral calcinoses in a chronic hemodialysis patient, based on a clinical case. CASE REPORT: A 62-year-old patient, chronic hemodialysis since 24 years, presented a mechanical pain shoulders, knees and hips with limitation of joint mobility...

OBJECTIVES: Lymphoedema is a dreadful complication following breast cancer therapy. According to the International Society of Lymphology, the consensus treatment for breast cancer-related lymphoedema (BCRL) is the decongestive lymphatic therapy. This is a two-phase treatment and combines different treatment modalities including skin care, manual lymphatic drainage (MLD), compression therapy and exercise. However, the additional effect of MLD is debated since pooled data only demonstrated a limited non-significant additional value...

We investigated the anatomical features of the axillary nerve and its accompanying vessels with respect to the lateral wall of the greater tuberosity, focusing on the relationship between the neurovascular bundle and the proximal humeral locking plates. Magnetic resonance images of 30 Japanese patients' shoulders were examined. Oblique sagittal images across the greater tuberosity and the neurovascular bundle, which contain the axillary nerve and posterior circumflex humeral artery and vein, were obtained. The distance between the superior aspect of the greater tuberosity and the superior and inferior borders of the neurovascular bundles was measured at the anterior, middle, and posterior edges of the greater tuberosity...

REVIEW
Lindsay S Flynn, Thomas W Wright, Joseph J King
Quadrilateral space (QS) syndrome (QSS) is a relatively rare condition in which the axillary nerve and the posterior humeral circumflex artery are compressed within the QS. Fibrous bands are most commonly implicated as the cause, with true space-occupying lesions being less common. QSS is characterized by poorly localized shoulder pain and paresthesia over the lateral aspect of the shoulder and arm in a nondermatomal pattern. These symptoms are aggravated by shoulder abduction and external rotation. Point tenderness is typically present over the QS; however, diagnosis on physical examination can be difficult...
