#1
J Kircher
Implantation of reverse shoulder endoprostheses is becoming more popular for elderly patients besides the well-established standard anatomic endoprostheses. The reasons for this are the increased life expectancy, age-dependent degeneration of the rotator cuff leading to cuff tear arthropathy, posttraumatic disability after failed osteosynthesis and primary reverse fracture arthroplasty. Stemless implants are more frequently used for primary osteoarthritis with the bone quality being the limiting factor. Modern implant systems allow the stepwise extension from bone preserving primary implants to modular and convertible revision implants that allow a partial exchange of components...

Complete pharyngo-oesophageal stricture (PES) after radiotherapy for head and neck cancer is a relatively rare and difficult complication to manage. Historically this condition has been treated surgically, but endoscopic approaches are now available. We present a 61-year-old man with an epidermoid carcinoma of the supraglottic stage and a micro-invasive epidermoid carcinoma of the oropharynx treated surgically and subsequently by adjuvant radiotherapy. Eight months after the end of the radiotherapy, a complete PES was diagnosed and treated with a combined anterograde-retrograde endoscopic dilation (CARD)...

Walking is a task that we seek to understand because it is the most relevant human locomotion. Walking causes complex loading patterns and high load magnitudes within the human body. This work summarizes partially published load data collected in earlier in vivo measurement studies on 9 patients with telemeterized knee endoprostheses, 10 with hip endoprostheses and 5 with vertebral body replacements. Moreover, for the 19 endoprosthesis patients, additional simultaneously measured and previously unreported ground reaction forces are presented...

AIMS: Extendible endoprostheses have been available for more than 30 years and have become more sophisticated with time. The latest generation is 'non-invasive' and can be lengthened with an external magnetic force. Early results have shown a worryingly high rate of complications such as infection. This study investigates the incidence of complications and the need for further surgery in a cohort of patients with a non-invasive growing endoprosthesis. PATIENTS AND METHODS: Between 2003 and June 2014, 50 children (51 prostheses) had a non-invasive growing prosthesis implanted for a primary bone sarcoma...

Endovascular aneurysm repair (EVAR) actually represents the treatment of choice for most patients affected by aneurysm of the abdominal aorta (AAA). However, the feasibility of EVAR depends on anatomical characteristics of abdominal aorta and ilio-femoral axis. We present the case of a 82-years old man affected by severe left hydronephrosis, kidney and ureteral tumor requiring nephrectomy, that presented also a very voluminous AAA with a large diameter (96 mm), presenting also with a large proximal neck (39 mm) and with a severe angulation of the proximal neck (> 60°)...

BACKGROUND: This work examines the hypothesis that in endoprosthesis implantation there are differences between experienced primary and senior caregivers (S-Op) and less experienced follow-up assistants (T-Op) with respect to process-relevant parameters. The main hypothesis is that compared to S‑Op, T‑Op cause significantly longer surgery times and thus additional operating theatre costs. As sub-hypotheses, differences in various perioperative (p-o) parameters between T‑Op and S‑Op were examined...

BACKGROUND: Patients with primary bone and soft tissue sarcoma are at risk for skeletal metastases. Although uncommon, these metastases can result in impending or pathologic fractures. Intramedullary nailing traditionally has been an accepted form of palliative treatment for patients with metastatic carcinoma, but we could find no studies that report specifically on intramedullary nailing of metastatic sarcoma lesions. QUESTIONS/PURPOSES: We asked: (1) What is the survival of patients with an impending or pathologic fracture from a sarcoma metastasis? (2) What proportion of patients treated with intramedullary nailing subsequently underwent a revision procedure or nail removal during their lifetimes? METHODS: Between 1996 and 2014, we performed 40 intramedullary nailing procedures in 34 patients with multifocal metastases from sarcomas who showed signs or symptoms of impending fracture or who presented with a pathologic fracture...

OBJECTIVES: A possible solution for the management of proximal femoral bone loss is a modular femoral endoprosthesis (EPR). Although the outcome of EPRs in tumour surgery has been well described, the outcome of their use in revision hip surgery has received less attention. The aim of this study was to describe the outcome of using EPR for non-neoplastic indications. METHODS: A retrospective review of 79 patients who underwent 80 EPRs for non-neoplastic indications was performed, including the rates of complication and survival and the mean Oxford Hip Scores (OHS), at a mean of five years post-operatively...

Self-expandable metallic stent (SEMS) was an effective biliary endoprosthesis. Mechanical properties of SEMS, radial and axial force (RF, AF), may play important roles in the bile duct after placement. RF was well known dilation force and influenced on the occurrence of migration. AF, newly proposed by this author, was defined as the recovery force when the SEMS vended. AF was related with the cause of bile duct kinking, pancreatitis, and cholecystitis due to the compression of the bile duct, orifice of the cystic duct, and pancreatic orifice...

Portal vein (PV) thrombosis (PVT) in the absence of liver disease or thrombophilia is rare. We report a 57-year-old male with a history of stage 3 chronic kidney disease who presented at the emergency department 18 months after abdominal surgery with progressive abdominal pain and distention. Computed tomography revealed PVT with multiple collaterals and moderate ascites. He had undergone partial gastrectomy and gastrojejunal anastomosis at an outside facility for gastrointestinal stromal tumors that caused an iatrogenic stenotic lesion in the PV...
