PURPOSE: CT-guided percutaneous transthoracic lung needle biopsy (PLB) is an effective procedure for obtaining cyto-histological diagnoses of peripheral lesions. However, upper postero-lateral lung nodules (UPLN) may be difficult to reach using a standard intercostal either anterior or lateral approach or when the nodule is just behind a rib or scapula. We evaluated the feasibility and effectiveness of trans-scapular approach (tPLB) in these patients using large-core needles. METHODS: We retrospectively collected the data of 11 consecutive patients (mean age 74...

We report the case of a 4-year-old girl with a biochemical relapse (plasma α-fetoprotein of 57,987.6 μg/L) after hepatoblastoma and extrahepatic metastases removal and adjuvant chemotherapy. Abdominal ultrasound, CT, and MRI failed to determine the site of recurrence. F-FDG PET/CT showed increased activity in the region of left scapula and adjacent soft tissue, which was incorrectly interpreted as the postoperative repair or inflammatory change. F-DOPA PET/CT showed increased activity and noticeable progressed lesion in the same place...

BACKGROUND: The range of motion of the glenohumeral joint varies substantially among individuals and is dependent on humeral position. How variation in shape of the humerus and scapula affects shoulder axial range of motion at various positions has not been established. PURPOSE: To quantify variation in the shape of the glenohumeral joint and investigate whether the scapula and humerus geometries affect the axial rotational range of the glenohumeral joint. STUDY DESIGN: Descriptive laboratory study...

Sigmodontinae rodents constitute the second-largest subfamily among mammals. Alongside the taxonomic diversity, they are also ecologically diverse, exhibiting a wide array of locomotion modes, with semifossorial, terrestrial, semiaquatic, scansorial, arboreal, and saltatorial forms. To understand the ecomorphologic aspects that allow these rodents to display such locomotion diversity, we analyzed 35 qualitative characters of the appendicular skeleton (humerus, ulna, radius, scapula, femur, tibia, ilium, ischium and pubis) in 795 specimens belonging to 64 species, 34 genera and 10 tribes, representing all locomotion modes assigned to this subfamily...

Human skeletal remains exhibit sexual dimorphism, which is apparent in adult living individuals as well. Researchers from forensic and osteoarchaeological fields have a growing interest in establishing metric standards for sexing by use of discriminant function analysis. The present study focuses on providing sex estimation metric standards using measurements from the scapula and clavicle in a Modern Greek sample (Athens Collection) consisting of 107 male and 90 female skeletons. A total of seven measurements were taken: maximum scapular height and breadth, glenoid cavity height and breadth, maximum clavicular length, anterior and superior clavicular diameter...

Berthold H Hell
There are several indications for resecting the bony chin, such as squamous cell carcinoma, sarcoma, or benign tumors of the jaw such as ameloblastoma. Several techniques for reconstruction of the bony chin, such as the use of metal plates and also revascularized free bone grafts of the iliac crest, fibula, or scapula, are common. In the case of poor vascular supply, however, alternative techniques may be necessary. In this report, a new technique is described using pedicled bone flaps from both sagittally split mandibular stumps following chin resection...

BACKGROUND: Movement faults are commonly observed in patients with musculoskeletal pain. The Kinetic Medial Rotation Test (KMRT) is a movement control test used to identify movement faults of the scapula and gleno-humeral joints during arm movement. Objective tests such as the KMRT need to be reliable and valid for the results to be applied across different clinical settings and patient populations. The primary objective of the present study was to determine the intra-rater and inter-rater reliability of KMRT in subjects with and without shoulder pain...

Shoulder impingement syndrome (SIS) is the common cause of shoulder pain and disability and the individuals suffering from it are usually in different levels of physical activity covering an extensive age range. In spite of limited scientific evidence for an altered motor pattern in the shoulder muscles of patients with SIS, they are frequently referred to physiotherapists in an attempt to optimize coordination and strength of the affected muscles. The aim of this study was to compare scapular muscle activity in a general population of subjects with and without SIS during an arm elevation task executed at different speeds in two load conditions...

BACKGROUND: The humeral subluxation index (HSI) is frequently assessed on computed tomography (CT) scans in conditions of the shoulder characterized by humeral displacement. An arbitrarily set HSI cutoff value of 45% for anterior subluxation and 55% for posterior subluxation has been widely accepted. We studied whether mean values and thresholds of humeral subluxation, in relation to the glenoid and scapula, were influenced by different imaging modalities. METHODS: The HSIs referenced to the scapula (SHSI) and glenoid (GHSI) were compared between conventional CT scans, CT scans reoriented into the corresponding reference plane (ie, scapular plane for the SHSI and glenoid center plane for the GHSI), and 3-dimensional (3D) CT reconstructions of 120 healthy shoulders...

BACKGROUND: Glenoid deficiency and erosion (excessive retroversion/inclination) must be corrected in reverse shoulder arthroplasty (RSA) to avoid prosthetic notching or instability and to maximize function, range of motion, and prosthesis longevity. This study reports the results of RSA with an angled, autologous glenoid graft harvested from the humerus (angled BIO-RSA). METHODS: A trapezoidal bone graft, harvested from the humerus and fixed with a long-post baseplate and screws, was used to compensate for residual glenoid bone loss/erosion...

This study compares the use of 0.05 and 0.10 alpha levels with the updated osteometric pair-matching model on two samples of the os coxa, scapula, and clavicle. The samples include the Forensic Data Bank, and the osteometric sorting reference used within the Defense POW/MIA Accounting Agency. Mixed-effects two-way analyses of variance were used to analyze bilateral asymmetry in the standard measurements. In total, 3,793,566 t-tests were conducted for osteometric pair-matching analysis. The results indicate high levels of exclusion power, and accuracy can be obtained with the os coxa and scapula...

BACKGROUND: Scapular winging resulting from long thoracic nerve palsy is uncommon but debilitating, and the choice of surgical treatment is inconsistent. The autogenous semitendinosus tendon plays a key role as an interposed tendon graft, although its use in the indirect transfer of the sternal head of the pectoralis major during the treatment of scapular winging has rarely been reported. MATERIALS AND METHODS: A retrospective review was performed during a 9-year period from the clinical data of 26 cases (28 shoulders) with indirect transfer of the sternal head of the pectoralis major with the interposition of an autogenous semitendinosus tendon graft for dynamic stabilization of the scapula...
