Release of the conjoined tendon has been reported to facilitate femoral exposure during a direct anterior hip approach. However, the authors are not familiar with any description of an anterior approach repair technique for this important structure. Conjoined tendon repair is commonly performed in the posterior approach to help preserve hip biomechanics and restore anatomic tissue planes. The authors describe their algorithm for sequential soft tissue releases to facilitate femoral exposure and a technique for repairing the insertion of the conjoined tendon after it has been released for exposure during the direct anterior approach...

BACKGROUND: Our understanding of fretting and corrosion at head-neck junctions in modular THAs in vivo is based largely on the analysis of retrieved implants removed for various diagnoses. Little is known about the condition of head-neck tapers in well-functioning THAs. QUESTIONS/PURPOSES: Regarding a cohort of well-functioning autopsy-retrieved modular THAs, we asked: (1) Does trunnion geometry or femoral head material affect the pull-off force of the femoral head? (2) Is there a relationship between trunnion damage and length of implantation time, head diameter, and neck length? (3) Does visual damage scoring accurately determine the presence or absence of corrosion on cobalt-chrome trunnions? METHODS: Sixty-six femoral stems and engaged femoral heads were retrieved at autopsy from 53 patients at Anderson Orthopaedic Research Institute from 1998 to 2014...

Given the lack of relevant data, the aim of this study was to examine femur cortical and trabecular bone in female and male professional ballet dancers. 40 professional ballet dancers and 40 sex- and age-matched non-exercising controls volunteered. Femoral bone density was scanned by dual-energy X-ray absorptiometry (DXA) scan. A 3D-DXA software was used to analyse trabecular and cortical bone. Anthropometry, maturation (Tanner staging), menstrual parameters (age at menarche and primary amenorrhea), energy availability and nutritional analysis (3-day record) were also assessed...

Transradial access for cardiac catheterization and percutaneous coronary intervention is recommended by international guidelines to reduce vascular complications. Unfortunately, some factors such as female sex, shorter body surface area and older age, were found to be independent predictors of transradial cardiac catheterization failure. The balloon-assisted tracking technique is a smart trick to avoid crossover from radial to femoral access in case of spasm, tortuosity, or stenosis.

The fusion of 3D anatomical models derived from high-fidelity pre-interventional computed tomography angiography (CTA), and x-ray (XR) fluoroscopy to facilitate anatomical guidance is of huge interest for complex cardiac interventions like TAVI procedures with cerebral protection. Co-registration of CTA and XR has been introduced either based on additional intraoperative non-/contrast-enhanced cone-beam computed tomography (CBCT) or two separate aortograms. With the related increase of radiation exposure and/or contrast agent (CA) dose, a potential additional risk for the patient is introduced...

Validity of the handheld Doppler to determine lower-limb blood flow restriction pressure for exercise protocols. J Strength Cond Res XX(X): 000-000, 2018-Handheld (HH) Doppler is frequently used for determining the arterial occlusion pressure during blood flow restriction exercises; however, it is unknown whether the blood flow is occluded when the auscultatory signal is no longer present...

Abaloparatide is a synthetic 34-amino acid peptide analogue of the 1-34 portion of the human parathyroid hormone-related protein (PTHrP). It has been approved in the U.S. for the treatment of postmenopausal women with osteoporosis at a high risk for fracture. Abaloparatide is an anabolic agent and it seems to have a potent anabolic activity with reduced effects on bone resorption. It reduces the risk of vertebral and nonvertebral fractures, major osteoporotic fractures and clinical fractures, with a significant improvement in bone mineral density at femoral neck, total hip and lumbar spine...

Background: Diagnosis of osteonecrosis of the femoral head (ONFH) is complicated due to the lack of reliable serum biomarkers. Up-regulation of alpha-2-macroglobulin (A2M) gene has been reported in glucocorticoid-induced ANFH rat model. This study aimed to investigate whether the serum level of alpha-2-macroglobulin (A2M) can be used for ONFH diagnosis. Methods: Serum protein capillary electrophoresis was performed on the sera of 36 ONFH patients. Also, human enzyme-linked immunosorbent assay was performed to evaluate the serum levels of A2M...

Background: There is a general consensus on the management of femoral fractures in children younger than two years and adolescents older than sixteen years. The best treatment for patients younger than sixteen years of age is still debatable. Titanium Elastic Nails (TEN), is widely used with some evidence, nonetheless, we undertook a systematic meta-analysis to assess the efficacy of TEN compared to Spica cast for the management of femoral shaft fracture in children aged between 2 to 16 years old...

Free-floating right heart thrombus (RHT) is an extreme medical emergency in the context of acute massive pulmonary embolism (PE). Despite the advances in early diagnosis, the management is still very debatable due to lack of consensus. We reported the case of a 66-year-old male, with a history of moderate renal dysfunction and dilated cardiomyopathy, who presented to the emergency department for acute dyspnea. His angiographic magnetic resonance imaging revealed bilateral extensive PE. Transthoracic echocardiography showed RHT with moderate right ventricular dysfunction and pulmonary hypertension...

Background: Failure of delivering a stent or a balloon across the target lesion during percutaneous coronary intervention (PCI) of chronic total occlusion (CTO), especially in arteries with calcified tortuous anatomy, is often due to insufficient backup support from the guiding catheter. The purpose of this study was to assess the feasibility of the GuideLiner (GL) catheter use. Methods: We examined 18 patients and used the GL catheter to overcome poor support and excessive friction in standardized antegrade and retrograde CTO procedures...

The storage of lipids as triglycerides (TG) and the de novo synthesis (lipogenesis) of fatty acids from non-lipid precursors (DNL) are important functions of adipose tissue (AT) that influence whole body metabolism. Yet, few studies have reported in vivo estimates of adipose lipid kinetics in humans. Fifty-two women with obesity (27 African-Americans; 25 Caucasians; 29.7 ± 5.5 years; BMI 32.2 ± 2.8 kg/m2 ; 44.3 ± 4.0% body fat) were enrolled in the study. In vivo synthesis (or replacement) of triglycerides (fTG ) and the synthesis of the fatty acid palmitate (measure of adipose de novo lipogenesis (fDNL )) were assessed using an 8-week incorporation of deuterium (2 H) into lipids (glycerol and palmitate moieties of TGs) in subcutaneous abdominal (scABD) and femoral (scFEM) AT...

BACKGROUND: The traditional goal of the gap-balancing method in total knee arthroplasty is to create equal and symmetric knee laxity throughout the arc of flexion. The purpose of this study was to (1) quantify the laxity in the native and the replaced knee throughout the range of flexion in gap-balancing total knee arthroplasty (TKA) and (2) quantify the precision in achieving a targeted gap profile throughout flexion using a robotic-assisted technique with active ligament tensioning...

OBJECTIVE: Midterm patency results of iliac vein stents placed for nonthrombotic iliac vein lesions (NIVLs) are not widely known. Previously published studies involving large series of patients with iliac vein stent placement have failed to clearly demonstrate the outcomes for patients with NIVLs and advanced disease. To further study this issue, we reviewed our series of 268 iliac vein stents placed for NIVLs. METHODS: Retrospective analysis was performed of 210 patients who underwent common or external iliac vein angioplasty and stent placement procedures between January 2013 and December 2014...

INTRODUCTION: With the advent of complex treatment techniques like volumetric modulated arc therapy, there has been increasing interest in treatment planning technologies aimed at reducing planning time. One of these such technologies is auto-planning, which is an automated planning module within Pinnacle3 . This study seeks to retrospectively evaluate the dosimetric quality of auto-planning-derived treatment plans as they compare to manual plans for intact prostate, prostate and lymph nodes, and brain treatment sites...
