PURPOSE: The aim of this study was to compare two methods of two-stage surgery for PJI (periprosthetic joint infection) after THA (total hip arthroplasty): one with and one without the use of an antibiotic-loaded cement spacer. METHODS: This retrospective study was performed on 99 consecutive patients (99 hips) with a minimum follow-up of 24 months. Patients were divided into two groups: (1) in whom the operation was performed using a spacer, and (2) for whom a spacer was not used...

OBJECTIVES: Outcomes after endovascular repair (EVAR) of ruptured abdominal aortic aneurysms (rAAAs) have been widely published. There is, however, controversy on the role of the use of aortouniiliac endoprosthesis (AUI) versus modular or unibody bifurcated endoprosthesis (MUB) for repair of rAAAs. We study and compare 30-day outcomes after use of AUI and MUB for all rAAAs focusing specifically on patients with instability. MATERIALS AND METHODS: Patients who underwent EVAR for rAAA (n = 425) using AUI (n = 55; 12...

BACKGROUND: Temporary placement of removable, fully covered, self-expandable metal stents (fcSEMS) for treatment of benign biliary strictures (BBS) has been reported to be effective. However, the optimal extraction time point remains unclear and stent migration has been a major concern. OBJECTIVE: The objective of this study was to evaluate the efficacy and safety of this treatment modality using an fcSEMS with a special antimigration design and prolonged stent indwell time...

Transcatheter aortic valve implantation (TAVI) is a validated technique for the treatment of aortic valve stenosis in patients with high surgical risk or inoperable. We present the case of an 80-year-old woman with severe aortic valve stenosis (mean gradient 55 mmHg), mild surgical risk, who refused traditional surgery. We implanted a Lotus Sadra 25 mm (Boston Scientific, Marlborough, MA, USA) via the transfemoral route. During pull back delivery, the patient experienced interscapular pain with angiographic evidence of type B aortic dissection effectively treated by implanting a vascular endoprosthesis Valiant 30 x 150 mm (Medtronic Vascular, Santa Rosa, CA, USA)...

AIM: extra-anatomic bypass (EAB) remains a viable alternative for lower limbs revascularization if aorto-bifemoral bypass and endovascular therapy are contraindicated. Among EAB, periprosthetic seroma (PS) occurs in about 4% of cases. Diagnostic and therapeutic management, as well as standardized treatment paradigm, are still not well defined. The aim of this study is to report 5 PS cases in EAB and to review literature about similar cases. METHODS: We retrospectively reviewed EAB performed during the period 2002-2015...

INTRODUCTION: Transcutaneous, bone anchored prostheses have proved to be an alternative for amputees. In addition to the safe osseointegration of the implant, the correct prosthetic alignment is also important. Therefore, the interaction between prosthesis components and the prosthesis wearer is significant and the role of the certified prosthetist should not be underestimated. AIM: The aim of treatment is the best possible compensation of disability after limb loss with increase of physical abilities and comfort of the prosthesis wearer by means of bone anchored prosthesis...

BACKGROUND: Distal femoral endoprosthesis (DFE) has become the optimal method of reconstruction in the skeletally mature patients treated for malignant bone tumor. Albeit literature has reported wide range of aseptic loosening in cemented components (6-32%), few authors showed that cement was not detrimental to long-term success of primary distal femoral implants possibly relating to cementing technique. METHODS: A series of consecutive of DFE (MRS and GMRS, Styker Orthopaedics, Mahwah, NJ) was retrospectively reviewed for evidence of loosening on plain radiographs...

Although significant progress has been made in the development of total hip replacement, behaviour of the femoral component of an endoprosthesis in relation to the type of its fixation in the bone is still not fully understood. In this paper, behaviour of the femoral bone and the stem prosthesis is studied taking into account different types of prosthesis fixation in the medullary canal of the femur under the action of functional loads. For an analysis, a three-dimensional model of a femur has been developed based on the results of a computed tomography...

AIMS: Instability of the hip is the most common mode of failure after reconstruction with a proximal femoral arthroplasty (PFA) using an endoprosthesis after excision of a tumour. Small studies report improved stability with capsular repair of the hip and other techniques, but these have not been investigated in a large series of patients. The aim of this study was to evaluate variables associated with the patient and the operation that affect post-operative stability. We hypothesised an association between capsular repair and stability...

The contribution of computing in the management of patients with pectus excavatum has greatly improved the aesthetic result of the reconstruction endoprosthesis. Computer aided design (CAD) enables the design of implants perfectly suited to the deformation of the patient and avoids approximations of the traditional technique of plaster mold. Although this technique is applicable in many areas, this article will only deal with pectus excavatum.

PURPOSE: Oncologic resections or complications of segmental femoral prostheses can result in severe bone loss of the femur for which a total femoral prosthesis (TFP) is required. This study assesses whether the loss of stability and function caused by the loss of muscle attachments can be improved by using a push-through total femoral endoprosthesis (PTTF), because it saves parts of the femur and its muscle attachments. METHODS: In this retrospective case series, ten patients aged 25-77 (mean 54) who received a PTTF between 2005 and 2014 were included for baseline, complications and survival analysis with a mean follow-up of 5...

The function of articular cartilage as an avascular tissue is mainly served by collagen type II and proteoglycan molecules. Within this matrix homeostasis between production and breakdown of the matrix is exceptionally sensitive. The current study was conducted to identify regional differences in specific alterations in cartilage composition during the osteoarthritic process of the human knee joint. Therefor the changes in the expression of the key molecules of the extracellular matrix were measured in dependence of the anatomical side (femoral vs tibial) and associated with immunohistochemistry and quantitative measurement...

Obstructive jaundice due to advance malignancy is a fatal problem. It most commonly occurs at the distal common bile duct or at the hilum of liver. Magnetic Resonance Cholangio Pancreatography (MRCP) and Computed Tomography (CT) are most useful in identifying the underlying cause as well as localize the position of the stricture. For those patients with unresectable disease, progressive jaundice constitutes an immediate threat to their survival, in addition to significant loss to their quality of life secondary to pruritus, malaise and cholangitis...

BACKGROUND The etiology of deep venous thrombosis (DVT) may pose a significant diagnostic challenge because truly reversible causes of DVT are rare. In this regard, known pelvic anatomic abnormalities such as aortic and iliac aneurysms should be seriously considered as a complicating factor in patients presenting with acute DVT so as not to miss a potentially curable etiology of May-Thurner syndrome (MTS). CASE REPORT We report the case of a 69-year-old man with a known abdominal aortic aneurysm and bilateral iliac artery aneurysms who presented with an acute DVT...
