Aims Extendible endoprostheses have been available for more than 30 years and become sophisticated with time. The latest generation is ‘non-invasive’ can be lengthened an external magnetic force. Early results shown a worryingly high rate of complications such as infection. This study investigates the incidence need further surgery in cohort patients non-invasive growing endoprosthesis. Patients Methods Between 2003 June 2014, 50 children (51 prostheses) had prosthesis implanted primary bone...
Expandable distal femur prostheses have become more popular over the last decades, but scientific data is limited.A retrospective study was performed, including cases treated between 1986 and 2019 in 15 European referral centers for bone sarcomas.A total of 299 were included. Average follow-up 80 months (range, 8-287 months). Mean patient age 10 years. Most (80%) implants noninvasive growers a fixed hinge knee used often (64%) than rotating hinge. prosthetic designs showed good (>80%)...
Intramuscular / cellular myxomas and low-grade myxofibrosarcomas are two different tumor entities with a significant histological overlap, especially if dealing small biopsies. Despite the morphological similarities, they differ considerably in their biological behaviour. myxoma rarely shows signs of recurrence never metastasizes, contrast to myxofibrosarcoma that tends recur more aggressively metastasize haematologically. Therefore, it is great importance distinguish these lesions -...
Treatment of unicameral bone cysts (UBC) in the humerus with drainage screws is scarcely reported literature. The aim this retrospective study was to compare and alternative treatment methods respect number required surgical procedures achieve sufficient UBC healing, postoperative fractures/recurrences/complications, radiological outcome. Medical archives two tertiary orthopedic referral centers were screened for all patients who treated surgically humeral period 1991–2015 a...
63 operativ behandelte juvenile Hüftkopflösungen (30 subkapitale und 33 Imhäuser-Weber Osteotomien) wurden nach durchschnittlich 10 Jahren nachkontrolliert. In beiden Osteotomiegruppen konnte der Epiphysenabrutsch durch die Operation meist vollständig korrigiert werden. Die funktionellen Ergebnisse waren in über 90% gut bis sehr gut. Radiologisch fanden sich bei den Fällen mit einer Verlaufszeit von 36% leichte degenerative Veränderungen. Osteotomie ist zu einem Gleitwinkel 60° subkapitalen...
Primary bone lymphomas (PBL) are extremely rare malignant neoplasms. The most commonly described subtype of PBL is diffuse large B-cell lymphoma (DLBCL). DLBCL within peri-prosthetic membrane a joint exceedingly rare. To the best our knowledge this case second reported Epstein-Bar-Virus (EBV) negative in literature. We report an 80 year old female patient who developed with chronic inflammation association to metallic implant left knee. This contrast usually was EBV by EBER situ...
The majority of patients with osteosarcoma and Ewing's sarcoma are diagnosed before skeletal maturity. Paley's multiplier is used for height prediction in healthy children, has been suggested as a method to make growth predictions children when considering limb salvage options. To our knowledge, no evaluation this particular patient group performed, but temporary deficit observed undergoing chemotherapy.We asked whether (1) formula reliably predicts who received polychemotherapy; (2)...
Introduction . Indications discussed for the implantation of expandable prostheses in bone sarcoma patients are unclear. This survey aimed to analyse common practice with this implant type orthopaedic oncology. Methods A web-based was sent 98 oncology surgeons. Factors reported literature influence decision on a growing prosthesis were covered individual questions and three case scenarios. Results The completion rate 45% ( n = 44). Twenty-seven 44 surgeons (61%) had implanted between 1 15...
Aims The use of a noninvasive growing endoprosthesis in the management primary bone tumours children is well established. However, efficacy such prosthesis those requiring revision procedure has yet to be aim this series was present our results using extendable prostheses for previous endoprostheses. Patients and Methods All patients who had inserted at time were identified from database. A total 21 (seven female patients, 14 male) with mean age 20.4 years (10 41) included. indications...
Secondary tumours of the ampulla Vater are rare. Underlying primary tumours, clinical presentation, macroscopic appearance, treatment strategies and outcome secondary ampullary lesions have not been systematically analysed. The present case study reported a 57-year old patient with an metastasis from renal cancer literature review was performed in which further 32 patients were included. most common responsible malignant melanoma clear cell carcinoma, followed by breast cancer. time interval...
Summary Background Osteoid osteomas of the foot are rare, with a varying and atypical clinical as well radiological presentation impeding early diagnosis treatment. The aim present multicentre study was to 1) analyze epidemiological, findings patients osteoid 2) deduce diagnostic algorithm based on findings. Methods A total 37 (25 males, 67.6%, mean age 23.9 years, range 8–57 years) were retrospectively included, treated between 2000 2014 at 6 participating tertiary tumor centres....
We analysed socio-economic- and health-related quality of life (primary outcome) radiological outcome (secondary 5 years after full time rigid bracing (FTRB) plus physiotherapeutic scoliosis-specific exercises (PSSE) in adolescent idiopathic scoliosis.We included 41 patients (38 female 3 male) treated with FTRB (Chênau brace) PSSE (Schroth) between 2001 2010. The study protocol a clinical examination, the completion SRS-24 questionnaire acquisition data on socio-economic factors (educational...
Low-grade central osteosarcoma is a very rare subtype of with predilection for the metaphysis long bones and peak incidence in 3(rd) decade life. Absence specific clinical symptoms good prognosis after wide resection are characteristics this entity. Chemotherapy not indicated highly differentiated tumour.A 12-year old girl presented limping, swelling pain mid left femur. Radiography showed 12 cm intraosseous expansion lamellated periosteal reaction contrast medium enhancement MRI. Although...
Sclerostin has been proposed as a potent inhibitor of bone formation. antibodies are under clinical development to treat osteoporosis and metastatic disease. Serum sclerostin level is elevated in multiple myeloma, an osteolytic malignancy, where it might serve predictive marker for the use sclerostin-directed antibodies. As renal cell carcinoma (RCC) patients often present with metastases, we aimed investigate serum levels RCC patients. Our study included 53 (19 25 visceral metastases 9...
