Arthroscopic surgery of the hip, compared to that of the knee or the shoulder, has only recently been developed in any significant way. Current indications for arthroscopic surgery of the hip include: diagnosis and treatment of lesions symptomatic of the acetabular labrum, femoroacetabular impingement (FAI), chondral lesions, joint infections, lesions of the teres ligament, impingement of the psoas tendon, pathology of the peritrochanteric space, external snapping hip (coxa saltans), and traumatic and atraumatic instability...

Pain is an unpleasant feeling that has been shown to be an important factor for the recovery of patients. Since this is costly in human resources and difficult to do objectively, there is the need for automatic systems to measure it. In this paper, contrary to current state-of-the-art techniques in pain assessment, which are based on facial features only, we suggest that the performance can be enhanced by feeding the raw frames to deep learning models, outperforming the latest state-of-the-art results while also directly facing the problem of imbalanced data...

PURPOSE: The gray-level histogram of ultrasound is a promising tool for scanning the hypoechogenic appearance of supraspinatus tendinopathy, and the aim of this study was to test the hypothesis that the gray-level value of the supraspinatus tendon in the painful shoulder has a lower value on B-mode images even though in different ultrasound devices. METHODS: Sixty-seven patients who had unilateral shoulder pain with rotator cuff tendinopathy underwent bilateral shoulder ultrasonography, and we compared the mean gray-level values of painful shoulders and contralateral shoulders without any pain in each patient using two ultrasound devices...

Diagnostic imaging plays an important role in the postoperative evaluation of the rotator cuff, as pain and disability may occur or persist after treatment. Postoperative imaging is therefore of paramount importance for clinicians before planning additional treatments. Multimodality imaging of the postoperative shoulder includes radiography, magnetic resonance (MR) imaging, MR arthrography, computed tomography (CT), CT arthrography, and ultrasound. Correct interpretation of imaging findings of the postoperative shoulder necessitates that the radiologist be familiar with the various treatment strategies, their possible complications and sources of failure, knowledge of normal and abnormal postoperative findings, and awareness of the advantages and weaknesses of the different imaging techniques...

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: Understanding the mechanisms of shoulder impingement created by clinical tests is crucial to accurately evaluate the condition. The objective of this study was to relate mechanisms of subacromial and coracoid impingement occurring in positions of the shoulder during clinical examination, in quantitative and qualitative terms. METHODS: A 1.0T open magnetic resonance imaging system was used in 18 female and 19 male subjects, to determine the distances between the humeral head and the acromion or coracoid, and contact with the rotator cuff (RC)...

Teres major muscle (TM) and latissimus dorsi muscle (LD) are frequently used in muscle transfers around the shoulder girdle. Some authors have suggested harvesting techniques in which the muscle is detached in continuity with a bone segment. Information on the bony attachment footprint of these muscles is lacking. The purpose of this study was to investigate the region of attachment of the TM to facilitate safe and complete harvesting with a bone segment where it is indicated, and to determine the relationship of the TM footprint with that of the LD...

A 28-year-old lady presented with multiple swellings in her left shoulder, associated with intermittent pain since last one and a half years. Radiologic imaging revealed multiple, well-defined, subcutaneous lesions in her left supraclavicular region. Fine needle aspiration cytology (FNAC) smears were initially reported as Ewing sarcoma, elsewhere. On review, the smears showed cohesive clusters of round-to-oval cells with scant cytoplasm, which were focally arranged in an acinar-rosetting pattern around hyaline "droplets/bodies," along with few scattered lymphocytes against a background of red blood cells...

Previous functional magnetic resonance imaging (fMRI) findings indicate that shoulder apprehension is more complex than a pure mechanical problem of the shoulder, showing a direct modification in functional brain networks associated with motor inhibition and emotional regulation. The current study extends these findings by investigating further structural alterations in patients with shoulder apprehension compared to controls. 14 aged patients with shoulder apprehension (27.3 ± 2.0 years) and 10 matched healthy controls (29...

Postoperative imaging in shoulder instability is still a challenge for radiologists due to various postsurgical anatomical findings that could be considered pathologic in treated shoulder. For this reason is very important a deep knowledge about surgical procedures, anatomical changes after surgery and the appropriate diagnostic imaging modalities to work up the symptomatic postoperative shoulder. Postoperative imaging options include use conventional radiography, magnetic resonance imaging (MRI), MRI arthrography, computed tomography (CT) and CT arthrography...

OBJECTIVE: Because positron emission tomography/computed tomography (PET/CT) using fluorine-18-fluorodeoxyglucose ((18)F-FDG) can be used to visualize inflammation of the musculoskeletal system, it may help elucidate the pathophysiology of frozen shoulder (FS). The purpose of this study was to characterize the uptake pattern on (18)F-FDG PET/CT in patients with idiopathic FS and to determine if there is a correlation between its metabolic parameters and clinical findings. METHODS: (18)F-FDG PET/CT was conducted to 35 patients with unilateral idiopathic FS...

INTRODUCTION: Synovial hemangioma is a developmental hamartoma of vascular tissue within the synovium; no cases involving the shoulder girdle have been described in the literature. Synovial chondromatosis is a benign condition in which synovial cells undergo metaplasia into hyaline cartilage and is also thought to infrequently affect the shoulder region. CASE REPORT: A 44-year-old female presented with left shoulder pain of 7-year duration. Magnetic resonance image displayed a 2...

BACKGROUND: Treatment of young, active patients with symptomatic glenohumeral osteoarthritis, excessive glenoid retroversion, and static posterior humeral subluxation is challenging. Correction of glenoid retroversion may lead to centric loading and perhaps recenter the humeral head. We describe the functional and radiologic outcomes after corrective osteotomy of the glenoid in this population of patients. MATERIALS AND METHODS: In this retrospective study, we included 10 shoulders (8 patients) that were observed for a mean of 33...

Only nine cases of bronchial granular cell tumor have previously been reported in pediatric patients. We present a 15-year-old girl with acute-onset right shoulder pain, discovered to have a granular cell tumor causing bronchial stenosis and a cavitating post-obstructive right upper lobe pneumonia. The patient was treated with lobectomy. Bronchial granular cell tumors are benign neoplasms that typically present with recurrent pneumonia. Imaging may demonstrate an endobronchial lesion or an associated post-obstructive opacity, but diagnosis requires tissue sampling...
