OBJECTIVE: This review was conducted to evaluate the types of endovascular procedures that can be performed via brachial artery access, evaluate the access success rate, and determine the incidence of technical complications. METHODS: A retrospective 10-year record review at a tertiary facility from January 1, 2005, through June 30, 2015, was completed. Patients who underwent attempted brachial artery access were eligible for review. Outcomes intended to be evaluated included ability to access the vessel, reach an identified lesion, and perform an indicated procedure, while describing the incidence and type of complications that occurred to clarify the utility and safety of brachial artery access...

Fractures of the proximal humerus are highly related to age and osteoporotic bone remodeling. Previous studies have highlighted the cortex as a major side of the bone loss, but the microstructural changes of the humerus have not been evaluated entirely. Sixty-four (n = 64) humeri of a representative collective (18-100 years) were scanned with high-resolution peripheral quantitative computed tomography (82 µm). Bone mineral density (BMD), trabecular bone volume fraction (Tb.BV/TV), cortical thickness (Ct...

Osteoporosis in laying hens has been a production and welfare concern for several decades. The objective of this study was to determine whether differing opportunities for exercise during pullet rearing influences long-term bone quality characteristics in end-of-lay hens. A secondary objective was to assess whether differing opportunities for exercise in adult housing systems alters bone quality characteristics in end-of-lay hens. Four flock replicates of 588 Lohmann Selected Leghorn-Lite pullets were reared in either conventional cages (Conv) or an aviary rearing system (Avi) and placed into conventional cages (CC), 30-bird furnished cages (FC-S), or 60-bird furnished cages (FC-L) for adult housing...

Hyaenodonta is a diverse clade of carnivorous mammals that were part of terrestrial faunas in the Paleogene of Eurasia and North America, but the oldest record for the group is Afro-Arabian, making the record there vital for understanding the evolution of this wide-spread group. Previous studies show an ancient split between two major clades of hyaenodonts that converged in hypercarnivory: Hyainailourinae and Hyaenodontinae. These clades are each supported by cranial characters. Phylogenetic analyses of hyaenodonts also support the monophyly of Teratodontinae, an Afro-Arabian clade of mesocarnivorous to hypercarnivorous hyaenodonts...

STUDY OBJECTIVE: Invasively monitoring blood pressure through the IO device has not been thoroughly demonstrated. This study attempted to establish baseline values of IO pressure in a healthy human population. METHODS: This was a prospective, healthy volunteer, observational study. Participants had two IO devices placed (humerus and tibia), and participant IO pressures, vital signs, and pain scores were monitored for up to 60 minutes. Participants were contacted at 24-hours and 7 days post-testing to assess for adverse events...

Proximal humerus fractures in the elderly are increasing in frequency as the population ages. The purpose of this study was to investigate surgical and cost trends in the Medicare population. The PearlDiver database was queried using diagnosis codes to identify Medicare recipients with proximal humerus fractures from 2005 to 2012. Surgical trends, demographics, and charge/reimbursement data were analyzed. There were 750,426 proximal humerus fractures in Medicare recipients during the 8-year period. Eighty-five percent of the fractures were treated nonoperatively; however, the percentage of operative vs nonoperative management increased significantly over time for all fractures, isolated fractures, and fracture dislocations...

Modeling and remodeling are two key determinants of human skeletal growth though little is known about the histomorphometry of cortical bone during ontogeny. In this study, we examined the density and geometric properties of primary and secondary osteons (osteon area and diameter, vascular canal area and diameter) in subperiosteal cortical bone from the human humerus (n = 84) between birth and age 18 years. Sections were removed from the anterior midshaft aspect of humeri from skeletons. Age-at-death was reconstructed using standard osteological techniques...

OBJECTIVE: To investigate the feasibility, surgical technique and effect of osteosynthesis for proximal humerus fractures through the minimal incision anterolateral acromion. METHODS: In this study, 32 patients of proximal humeral fractures were selected and treated through the minimal incision antero-lateral acromion between January 2012 and October 2014. Of these patients, there were 19 males and 13 females, with mean age 46 years old (range: 22-78 years). The mechanism of injury was a trauma of simple fall for 21 patients and motor vehicle accident for 11 patients...

BACKGROUND: With the introduction of the deltoid tuberosity index (DTI), a simple radiographic tool has become available to measure bone mineral density of the proximal humerus. The aim of this study was to assess the influence of local bone mineral density on the early failure rate after angular stable open reduction-internal fixation of proximal humeral fractures (PHFs). METHODS: We retrospectively followed up all patients treated with angular stable implants for PHFs from 2007 to 2014...

Fractures of the upper limbs are frequent and often need operative treatment in addition to a well-indicated conservative management. This depends on the maturity of the nearest growth plate and the local remodeling potential, which is dependent on age. Following conventional x‑ray imaging an individual prognostic growth analysis leads to the therapeutic decision. Around the elbow and the shaft of the forearm, criteria are stricter than near the shoulder or wrist. Gilchrist or Desault bandages as well as braces are adequate for most subcapital and humeral shaft fractures...

Shoulder fracture-dislocations are uncommon. Those associated with intrathoracic dislocation are very rare conditions, resulting from high-energy trauma; usually, the affected limb is in an abduction position. In Brazil, there is only one report of a teenager with displacement of the epiphysis into the chest cavity; the present is the first adult patient report of intrathoracic dislocation of the humerus. The authors present the case of a patient female, aged 56 years, who was hit by motorcycle and thrown approximately 5 meters away...

BACKGROUND: Isolated coronoid, isolated radial head, and combined coronoid and radial head fractures are common elbow fractures, and specific ligamentous injury of each fracture configuration has been reported. However, the osseous injury mechanism related to ligament status remains unclear. QUESTIONS/PURPOSES: The objectives of this study were: (1) to determine what ligamentous injury patterns (medial or lateral collateral) and bone contusion patterns (medial or lateral) are associated with isolated coronoid, isolated radial head, and combined coronoid and radial head fractures; (2) to correlate the osseous injury mechanism based on these findings with isolated coronoid, isolated radial head, and combined coronoid and radial head fractures; and (3) to determine whether isolated and combined coronoid fractures have different fracture lines through the coronoid (tip or anteromedial facet), speculated to be caused by different injury mechanisms...

Humeral cement removal in revision shoulder arthroplasty can be challenging. Secondary damage to the bone and neighbouring structures can be extensive and compromise later reconstruction. We present a technique that employs flexible reamers from elbow arthroplasty instrumentation, which aids cement removal at the same time as minimizing the risk of iatrogenic injury.

BACKGROUND: Proximal humeral fractures in elderly patients present with severe comminution and osteoporotic bone quality. Reverse shoulder arthroplasty has lately been proven beneficial in treating patients with complex proximal humeral fractures. The above technique is recommended and has better results in elderly than in younger individuals. METHODS: We performed a literature search in the databases Pubmed, Medline, EMBASE and Cochrane Library for published articles between 1970 and 2016 using the terms: proximal humerus fractures and reverse shoulder arthroplasty...

Gorham's disease is a rare disorder of the bone characterized by progressive massive osteolysis. The pathophysiology is unknown, and diagnosis is often difficult. Most cases are often recognized retrospectively. There is no standardized treatment and management for Gorham's disease. We report a case of an 18-year-old male presenting with a pathologic fracture in the humerus shaft diagnosed with Gorham's disease. Patient was treated with autogenous vascularized fibular graft with wide excision and a 10 years followup after first surgery...

BACKGROUND: Nontuberculous mycobacteria (NTM) were considered saprophytic organisms for many years but now are recognized as human pathogens. Although humans are routinely exposed to NTM, the rate of clinical infection is low. Such infections usually occur in the elderly and in patients who are immunocompromised. However, there has been an increasing incidence in recent years of infections in immunocompetent hosts. NTM infections in immunocompetent individuals are secondary to direct inoculation either contamination from surgical procedures or penetrating injuries rather than hematogenous dissemination...

Alterations have been made over the years to the standard reverse total shoulder arthroplasty (RTSA) prosthetic components in an effort to decrease adverse events; this has led to the advent of a short humeral stem prosthesis. To the authors' knowledge, there are no reports describing the complication of a traumatic periprosthetic Wright and Cofield classification type A fracture with use of a short metaphyseal humeral stem component for RTSA. The authors describe a 49-year-old woman with this pathology who was treated with open reduction and internal fixation using a proximal humerus locking plate, unicortical and bicortical screw fixation, and a cerclage wire construct without the need to violate the shoulder joint or revise components...

BACKGROUND: Recently, there has been an emphasis on improving quality, safety, and value in the delivery of health care in the United States. The American Board of Orthopedic Surgery (ABOS) has developed a performance improvement questionnaire (PIQ) for orthopaedic surgeons managing pediatric supracondylar humerus fracture (PSCHF). Using the supracondylar PIQ as a guide, this study evaluates the process of measuring the outcomes and variations in care to PSCHF patients among pediatric orthopaedic surgeons...

Physical activity benefits the skeleton, but there is contrasting evidence regarding whether benefits differ at different stages of growth. The current study demonstrates that physical activity should be encouraged at the earliest age possible and be continued into early adulthood to gain most skeletal benefits. INTRODUCTION: The current study explored physical activity-induced bone adaptation at different stages of somatic maturity by comparing side-to-side differences in midshaft humerus properties between male throwing athletes and controls...

Brachial plexus birth palsy resolves spontaneously in a majority of patients, however, others may have serious permanent dysfunction. Although nerve transfers or grafts are early options for treatment, many children have residual deficits or present too late for such procedures. In these patients, rotational osteotomy of the humerus may restore improved function and motion. Unfortunately, traditional humeral osteotomies only provide correction in a single plane, therefore appropriate correction of the typical residual deformity is incomplete...
