We report a 72-year-old man who underwent fixation with a multifilament cerclage system after a peri-prosthetic trochanteric fracture (Vancouver A1). Failure of cerclage occurred after 23 month and revision of trochanteric attachment was performed due to non-union. Intraoperatively fragments of the cable were found between prosthesis head and liner. Cup and head were changed and the greater trochanter was re-attached after allograft-impaction. Based on the present case report multifilament cerclage cables should be used with precaution and might require a close and frequent follow-up given the possibility of cerclage breakage and consecutive catastrophic wear by migration of cerclage particles...

REVIEW
R Windhager, G M Hobusch, M Matzner
A combination of allogeneic and autologous bone transplants is frequently used for the biological reconstruction of bone defects. Autologous bone transplants can be used either in the form of structural or cancellous bone transplants. The osteogenic potential of autologous cancellous bone is well-known and is still the gold standard with respect to osteoinduction and remodelling. Structural transplants, such as fibular and tricortical iliac crest grafts can be transplanted either free, i.e. non-vascularized or vascularized with anastomosed vessels...

BACKGROUND: The hip is a common location for metastatic tumors. Due to the high loads placed through the proximal femur, surgery is often indicated to provide pain relief and restore function. Historically, these lesions are reconstructed with a hemiarthroplasty; however, there are few reports on the outcome of these reconstructions. The purpose of this study is to evaluate the outcome of hemiarthroplasty for the treatment of proximal femur metastatic disease, with a specific focus on the rates of conversion to total hip arthroplasty (THA)...

INTRODUCTION: Treatment of fractures in the elderly population is a clinical challenge due partly to the presence of comorbidities. In a Geriatric Fracture Centre (GFC), patients are co-managed by a geriatrician in an attempt to improve clinical outcomes and reduce morbidity and mortality. Until now the beneficial effect of orthogeriatric co-management has not been definitively proven. The primary objective of this study is to determine the effect of GFC on predefined major adverse events related to a hip fracture compared to usual care centres (UCC)...

Superior vena cava (SVC) syndrome, characterized by facial and arm swelling, is most frequently caused by intrathoracic malignancies. Decompression may be achieved with endovenous stent placement. Polytetrafluoroethylene-covered stents have shown to have higher long-term cumulative patency rates compared with uncovered stents for the treatment of malignant SVC syndrome. Unfortunately, polytetrafluoroethylene-covered stents are not readily available worldwide. Moreover, the existing armamentarium, including balloon-expandable iCAST stents (maximum diameter 10 mm) and heparin-coated Viabahn stent-graft endoprostheses (maximum diameter 13 mm), are too small to adequately treat malignant obstruction of the SVC...

BACKGROUND: We analyzed trends, assessed outcomes and lessons learned, and investigated whether using a simplified US version of the frozen elephant trunk (FET) technique to treat complex arch pathology poses additional risk. METHODS: From 2010 to 2015, we performed 129 consecutive ET procedures (traditional ET [t-ET], n = 92 [71.3%]; FET, n = 37 [28.7%]) for chronic dissecting (n = 62 [48.1%]) and atherosclerotic aneurysms (n = 67 [51.9%]). A stepwise logistic regression model using preoperative and intraoperative variables was created to analyze the outcomes...

BACKGROUND: Proximal end of the humerus is a common site for both primary and metastatic bone tumors. Limb salvage with endoprosthetic replacement is the most common means of reconstruction, but it has been proved that cement spacer are more beneficial for inferior shoulder function. Thus, limb salvage can be replaced by cheaper spacers especially in poor societies. PATIENTS AND METHODS: This study included 20 patients, of whom 14 were female, with a mean age of 40...

We report a 78-year-old man who presents progression of his aneurysmatic pathology with previous abdominal infrarenal aortic surgery 20 years later. The computed tomography (CT) scan showed proximal degeneration of the infrarenal aorta, left iliac aneurysm and a new descending thoracic aneurysm close to the aortic arch. The surgical treatment was staged in two times due to the evolution of the aneurysm measures. First, the thoracic and the infrarenal aneurysms were covered each one with endoprosthesis. Four years later the iliac disease was solved with a branched specific iliac endograft...

BACKGROUND AND AIMS: A postsurgical anatomy renders endoscopic sphincterotomy (EST) more challenging. Although different EST techniques for such a situation exist, comparative studies are lacking. The aim of the study was to compare the efficacy of different EST techniques using a novel mechanical simulator. METHODS: Ten expert endoscopists performed 6 different EST techniques on a novel mechanical Billroth II (BII) simulator in a random sequence. The EST techniques were (1) standard sphincterotome used with a side-viewing endoscope, (2) BII sphincterotome used with a side-viewing endoscope, (3) needle-knife EST guided by biliary endoprosthesis used with a side-viewing endoscope, (4) standard sphincterotome used with a forward-viewing endoscope, (5) BII sphincterotome used with a forward-viewing endoscope, and (6) needle-knife EST guided by biliary endoprosthesis used with a forward-viewing endoscope...

The GORE TAG Thoracic Endoprosthesis (TAG) device (W. L. Gore & Associates, Flagstaff, Ariz) and the GORE Conformable TAG Thoracic Endoprosthesis (CTAG) are commonly implanted and effective stent grafts for use during thoracic endovascular aortic repair. Precise placement of the endograft is paramount during thoracic endovascular aortic repair, but like all thoracic stent grafts, maldeployment with inaccurate landing has been reported. The partial distal deployment technique describes an alteration of the TAG and CTAG deployment mechanism to allow isolated deployment of the distal half of the graft, which provides stability during deployment...

Within the last ten years of biomedical implants, the focus is increasingly on bioceramics, specifically on zirconia (ZrO2 ). Hence, we analyzed the impact of ZrO2 particles in comparison to titanium particles on mature human osteoclasts (OCs) as little is known about the direct effect of wear particles on mature OCs and their role in the osteolytic process during aseptic endoprosthesis loosening. Changes in cell morphology and functionality of OCs incubated with particles in different concentrations were investigated in vitro...
