INTRODUCTION: Bilateral common iliac artery (CIA) aneurysm (CIAA) is a rare entity. In the past decade, different endovascular approaches have been adopted for patients with several comorbidities or unfit for open repair (OR). Recently, the use of iliac branch stent graft has been proposed, resulting in satisfactory patency rates and decrease in morbidity. Currently, according to instruction for use, the iliac branch stent graft is to be used with aortobi-iliac stent graft conjunction...

INTRODUCTION: There are currently no available prostheses that can be used for extremely small femurs or tibias of adult patients in countries where allograft is unavailable. CASE REPORT: We report the case of a 17-year-old girl requiring special limb salvage technique for distal femur reconstruction following resection of malignant tumor. This technique was needed because of a very narrow canal of the tibia. We split bilateral tibial cortices longitudinally with osteotomies to enlarge tibial canal enough to insert conventional endoprosthesis...

BACKGROUND: Endoprostheses using principles of compressive osseointegration have shown good survivorship in several studies involving the lower extremity; however, no series to our knowledge have documented the use of this technology in the management of massive bone loss in the upper limb. QUESTIONS/PURPOSES: (1) What proportion of upper extremity implants using compressive osseointegration fixation principles achieved durable short-term fixation, and what were the modes of failure? (2) What surgical complications resulted from reconstruction using this technique? METHODS: A multiinstitutional retrospective review identified nine patients (five women; four men) who underwent 13 endoprosthetic replacements between 2003 and 2014 using compressive osseointegration (Compliant(®) Pre-stress Device [CPS]; Biomet Inc, Warsaw, IN, USA) in the upper extremity, including two proximal humeri, two humeral diaphyses, seven distal humeri, and two proximal ulna...

BACKGROUND: Clinical success of TKR depends to a large extent on the correct positioning of the implants. The femur cut is usually made in 3° of external rotation relative to the posterior aspect of the femoral condyles, which is a typical value of the Posterior Condylar Angle (PCA). The aim of this study was to assess variation in the PCA and to identify possible correlations between the value of the PCA and the following parameters: gender, body side, body height and weight (BMI). MATERIAL AND METHODS: The study group comprised 75 patients who underwent an Angio-CT study between 2012 and 2014 due to a suspected vascular disorder...

BACKGROUND: Understanding that the common iliac arteries (CIA) are shorter in Asian patients, we investigated whether this anatomic difference affects the clinical outcomes of internal iliac artery (IIA) exclusion during endovascular aneurysm repair (EVAR) of aortoiliac aneurysm and thus limits the use of IIA-preserving devices in Japanese patients.Methods and Results:From 2008 to 2014, 69 Japanese patients underwent EVAR of aortoiliac aneurysms with 53 unilateral and 16 bilateral IIA exclusions...

The aim of implantation of cementless hip prostheses is vital ingrowth of bone into the structured metal surface of the implant. Since the 1960s several implants with surfaces made of cobalt-based alloys have been produced for this purpose. In the 1980s a novel hip endoprosthesis with a spongiosa-metal surface was introduced. The three-dimensional ingrowth of bone tissue into the structured surface of the implant could be demonstrated both histologically and using scanning electron microscopy (SEM). These implants made of cobalt-based alloys can also be used in endo-exo prostheses...

: We present a novel technique for accurate whole body attenuation correction (AC) in the presence of metallic endoprosthesis, on integrated non-time-of-flight (non-TOF) PET/MR imaging scanners. The proposed implant PET-based attenuation map completion (IPAC) method performs a joint reconstruction of radioactivity and attenuation from the emission data to determine the position, shape and linear attenuation coefficient (LAC) of metallic implants. METHODS: The initial estimate of the attenuation map is obtained using the MR Dixon-method currently available on the Siemens Biograph mMR scanner...

INTRODUCTION: Although the use of an endoprosthesis for distal femoral fractures remains a valid treatment option the widespread use is in its infancy. METHODOLOGY: In this retrospective case series, we review cases of distal femoral fracture treated with endoprosthetic replacement (EPR). The outcomes we assessed were the time to start mobilising, the time to discharge, morbidity and mortality as well as an Oxford knee score to assess pain and function and also the early survivorship...

BACKGROUND: The most cost-effective reconstruction after resection of bone sarcoma is unknown. The goal of this study was to compare the cost effectiveness of osteoarticular allograft to endoprosthetic reconstruction of the proximal tibia or distal femur. METHODS: A Markov model was used. Revision and complication rates were taken from existing studies. Costs were based on Medicare reimbursement rates and implant prices. Health-state utilities were derived from the Health Utilities Index 3 survey with additional assumptions...

BACKGROUND: Thoracic endovascular aortic repair (TEVAR) requires large-bore vascular access due to the considerable diameters of the endoprosthesis and delivery device. The preclose technique preceding endograft delivery has opened the door for an evolved access strategy. In addition, treatment under local anesthesia offers the advantage of optimal neuromonitoring. The goal of this study was to analyze the efficacy and safety of percutaneous TEVAR under local anesthesia. METHODS: All patients undergoing TEVAR in an elective setting at the Antwerp University Hospital between June 2012 and June 2015 were prospectively entered into an endovascular database...

Background Giant cell tumors (GCTs) are rare osseous tumors that rarely appear in the skull. Methods We review the clinical course of a 28-year-old previously healthy woman with a complicated GCT. Results The reviewed patient presented with a middle cranial fossa tumor acutely complicated by reactive mastoiditis. Left tympanomastoidectomy was performed for drainage of the mastoiditis and for biopsies of the tumor. Due to the challenging tumor location, the patient was treated with denosumab, a fully humanized monoclonal antibody against receptor activator of nuclear factor kappa-B ligand, for 7 months, which resulted in significant preoperative tumor shrinkage...

The authors present the case of a patient with a giant cell tumor of the left femoral neck, with adjacent progressive invasion of bone tissue. Initial treatment was done with local curettage and autologous bone graft from fibula, electrocauterization and filling with methyl methacrylate. A local tumoral relapse was present after one year; therefore a new surgical procedure was necessary, with proximal femoral wide resection and unconventional endoprosthesis fixation. The article discusses the clinical aspects and surgical treatment...

Comminuted fractures of the elbow are very rare and in most cases very complex and the successful treatment can be a challenge for the treating surgeon. Due to the elbow joint's complex functional anatomy, the multi-fragmentary nature of many fractures and concomitant destabilizing associated injuries, comminuted fractures of the elbow still present a serious challenge for the orthopedic surgeon. Especially in more severe communicated injuries an osteosynthesis or endoprosthesis must be discussed with the patient...

Osteosarcoma, a bone cancer most commonly seen in adolescents and young adults, is usually a high-grade malignancy characterized by a very high risk for the development of pulmonary metastases. High-grade osteosarcomas are usually treated by preoperative and postoperative chemotherapy and surgery, with a very limited number of active agents available. Rarer lower-grade variants such as parosteal and periosteal osteosarcoma or low-grade central osteosarcoma are treated by surgery only. Imaging to search for possible metastases focuses on the lung...

REVIEW
N J Hilliard, P Hayes, A P Winterbottom
The Nellix stent graft has novel features that influence interpretation of imaging follow-up, in particular, the use of endobags that seal the aneurysm sac. The polymer within the endobags contains a small amount of contrast medium, which causes a predictable temporal change in appearances. Understanding of these features allows correct image evaluation. In this article, we review the appearance of Nellix on computed tomography, ultrasound, magnetic resonance imaging, and plain radiography. We describe the special considerations that are important to consider when reviewing imaging, including endobag position and seal, endobag configuration, endobag and polymer maturation, and endobag gas...

Background: An increasing number of physically active patients not only need to know if they will basically be able to engage in sports after undergoing arthroplasty. They also would like to know whether or not they will be able to resume their preoperative activity levels. This article aims to provide an overview of recent data regarding the following questions on hip, knee and shoulder arthroplasty: (1) What is the impact of physical activity on an endoprosthesis? (2) What level of sports can be achieved after an arthroplasty procedure? (3) What types of sport are recommended for patients with an endoprosthesis? Methods: PubMed-based review of the literature...

Periprosthetic femoral fractures can be categorized into proximal fractures around a hip stem or distally around a knee arthroplasty. This paper focuses on the proximal periprosthetic fractures. It is important to classify the fracture at diagnosis and to perform accurate planning of the surgery. Basically it is necessary to decide if the implant is fixed or loose, in the latter case a revision surgery including the change of the endoprosthesis is neccessary. If the implant is fixed an open reduction and internal fixation can be done...
