CASE: We describe the case of a 66-year-old man who sustained a nondisplaced radial neck fracture and subsequently developed a symptomatic nonunion. After a period of unsuccessful conservative treatment, a radial head resection was performed. CONCLUSION: Radial neck fractures, unlike their radial head counterparts, have a low rate of nonunion. Our patient's only positive risk factor was age, but he developed a nonunion. At the 2-year follow-up after excision of the radial head, there was a lack of proximal migration of the radius during axial loading, demonstrating a positive outcome without the need for replacement of the radial head...

PURPOSE: Direct location of a "safe zone" on a CT axial view is inadequate because the radial head is circular in shape. Previous "safe zone" location methods are not appropriate if the physician is unable to visualize the actual radial head. This study aims to introduce a new method to locate the "safe zone" on CT. METHODS: CT scans were performed on 20 intact cadaveric upper limbs from 20 different corpses in full pronation and supination. The DICOM-format raw data were then re-sliced and analyzed in Mimics 17...

The most commonly used method of operating landfills more sustainably is to promote rapid biodegradation and stabilization of municipal solid waste (MSW) by leachate recirculation. The present study is an application of computational fluid dynamics (CFD) to the 3D modeling of leachate recirculation in bioreactor landfills using vertical wells. The objective is to model and investigate the hydrodynamic and biochemical behavior of MSW subject to leachate recirculation. The results indicate that the maximum recirculated leachate volume can be reached when vertical wells are set at the upper middle part of a landfill (H W/H T = 0...

Distal ulnar fractures often occur with distal radius fractures (DRFs), and ulnar styloid fractures commonly occur in the setting of DRF. However, isolated ulnar head fractures are rare. We report a case of isolated ulnar head fracture in which we performed bone resection because the ulnar head bone fragment fractured when internal screw fixation was attempted. His outcome at 18 months postoperatively was considered excellent. However, we do not advocate bone resection other than failure of fixation and the difficult case to perform internal fixation...

The median nerve passes through the humeral and ulnar heads of the pronator teres muscle (PT), although variations such as absence of the ulnar head may exist. We observed histological sections of the upper extremity from 24 embryos and fetuses. In the early stage, the PT extended between the radius and the medial epicondyle of the humerus, but no candidate for the ulnar head was found. In mid-term fetuses, the ulnar margin of the PT was attached to the elbow joint capsule. Moreover, in late-stage fetuses, a small deep part of the PT arose from the thick joint capsule of the humero-ulnar joint near the coronoid process of the ulna...

Background: Various deformities can occur in the forearm bones when the traumatically dislocated radial head is untreated for a long period. Without correction of all deformities, reduction of the dislocated radial head is difficult to maintain, and forearm and elbow motion will deteriorate after reduction. We evaluated radiographic parameters of forearms with traumatically dislocated radial heads (and of the normal sides) to understand the resulting deformities and the effectiveness of surgical treatment...

The aim of the study is to provide some characteristic parameters of the anatomy of metatarsals from computed tomography (CT) scans. These data are important for more anatomical metatarsal head resurfacing prosthesis conception. Measures were performed on 20 CT scans from 17 patients with a mean age of 44.35 ± 15.75 years old. The panel was composed of 40% male and 50% left feet. Measurements were divided in 2 distinct categories: linear measurements with length of metatarsal, head radius and head, and diaphysis and base thicknesses, and cross-sectional area measurements, including cortical and cancellous bone area at 10%, 25%, 50%, 60%, 75%, and 90% of the metatarsal's length...

Most antivirals target viral proteins and are specific for only one virus, or viral type. Whereas viral proteins are encoded in the plastic viral genome, virion lipids are not and their rearrangements during fusion are conserved among otherwise unrelated enveloped viruses. Antivirals that inhibit these lipid rearrangements could thus pose a high barrier to resistance and have broad-spectrum activity. Fusion occurs through a hemifusion stalk in which only the outer leaflets are fused and thus curved with a smaller radius for the polar heads than for the hydrophobic tails (negative curvature)...

BACKGROUND: Fractures of the radial shaft with disruption of the distal radial ulnar joint (DRUJ) or Galeazzi fractures are treated with reduction of the radius followed by stability assessment of the DRUJ. In rare instances, the reduction of the DRUJ is blocked by interposed structures requiring open reduction of this joint. The purpose of this study is to review all cases of irreducible Galeazzi fracture-dislocations reported in the literature to offer guidelines in the diagnosis and management of this rare injury...

INTRODUCTION: We performed an external validation of the arterial-based complexity (ABC) score using a head-to-head comparison with the R.E.N.A.L. (radius, exophytic/endophytic tumor properties, nearness of tumor to deepest portion of collecting system or sinus, anterior/posterior descriptor, location relative to the polar line), PADUA (preoperative aspects and dimension for anatomic classification of renal tumors), and C-index scores for the prediction of surgical outcomes after partial nephrectomy...

Clustering is an efficient approach in a wireless sensor network (WSN) to reduce the energy consumption of nodes and to extend the lifetime of the network. Unfortunately, this approach requires that all cluster heads (CHs) transmit their data to the base station (BS), which gives rise to the long distance communications problem, and in multi-hop routing, the CHs near the BS have to forward data from other nodes that lead those CHs to die prematurely, creating the hot zones problem. Unequal clustering has been proposed to solve these problems...

OBJECTIVE: The aim of this study was to investigate the effects of normalized muscle tension via tensegrity-based massage on postural stability in a sample of female young adults. METHODS: Nineteen females aged 21.8 ± 1.9 years were recruited presenting abnormal tension at muscles adhering to any of the following structural sites: superior iliac spine, lateral sacropelvic surface, linea aspera at 1/2 of femur length, and superior nuchal line of the occiput. Balance and postural control were assessed during bipedal stance using a force platform in multiple conditions: hard surface or soft foam surface with the head in either a neutral posture or tilted backward...

OBJECTIVES: To evaluate the reliability of CT measurement of canine elbow axial radioulnar congruence using a duplicated circle superimposition technique. MATERIALS AND METHODS: CT of six cadaveric canine elbows was performed following either: (1) placement of an external fixator on the radius with ostectomy and radial shortening of 1 to 5 mm; (2) radial lengthening of 1 to 5 mm using a radial lengthening system; or, (3) no axial length adjustment. Four observers, on two occasions, blinded to the amount of radial adjustment, placed a circle of best fit of the ulnar trochlear notch on a sagittal image that was duplicated and transposed to the articular contour of the radial head; then the axial distance between circles relative to the dorsal radius was measured...

In this report we present a case of re-stabilization of the proximal radius using vascularized free fibular graft combined with anconeus arthroplasty to stabilize the transplanted fibula in a patient with large loss of the proximal radius due to Ewing's sarcoma. A 20-year-old woman had Ewing's sarcoma in the proximal three-fourths of the radius. The resection of large part of the radius containing radial head were necessary for removal of the sarcoma. Reconstruction of the proximal radius was performed using vascularized free fibular graft and the transplanted fibula was stabilized by attaching the anconeus to the proximal edge of the fibula...

BACKGROUND: The chronic use of antipsychotics has been associated with impaired bone mineralization, partially mediated by hyperprolactinemia. We examined if calcium and vitamin D supplementation promote bone mineral accrual in boys with risperidone-induced hyperprolactinemia. METHODS: Between February 2009 and November 2013, medically healthy, 5- to 17-year-old boys were enrolled in a 36-week double-blind, placebo-controlled study, examining the skeletal effects of supplementation with 1250 mg calcium carbonate and 400 IU of vitamin D3 in risperidone-induced hyperprolactinemia...

Recombinant Elastin-Like Polypeptides (ELPs) serve as attractive scaffolds for nanoformulations because they can be charge-neutral, water soluble, high molecular weight, monodisperse, biodegradable, and decorated with functional proteins. We recently reported that fusion of the FK-506 binding protein 12 (FKBP) to an ELP nanoparticle (FSI) reduces rapamycin (Rapa) toxicity and enables intravenous (IV) therapy in both a xenograft breast cancer model and a murine autoimmune disease model. Rapa has poor solubility, which leads to variable oral bioavailability or drug precipitation following parenteral administration...

INTRODUCTION: Generally, anatomical reduction of shaft fractures through operative treatment is necessary to restore the anatomical relationship of the forearm bones. However, a number of nerves and vessels are located in the proximal radius, which complicates surgery. In this study, we aimed to reduce postoperative complications by using a posterior approach. PRESENTATION OF CASE: We describe an isolated fracture through the radial bicipital tuberosity in a 69-year-old man caused by direct blunt force and our management of the fracture...
