Ontwikkelen, verbinden & bewegen

Ontwikkelen, verbinden en bewegen: het begint in een universiteit waar iets ontwikkeld wordt, vervolgens wordt het in verbinding gebracht met het werkveld en daar in beweging gezet. Dat leidt weer tot nieuwe vragen en de zoektocht naar ontwikkeling en zo verder.De zorg voor orthopedische patiënten is momenteel lastig in de gewone ziekenhuiszorg omdat er schaarste is aan personeel en operatieruimte. Als orthopedische patiënt hoef je niet acuut geholpen te worden, je gaat immers niet meteen dood. Maar je bent wel ernstig beperkt en je hebt veel pijn!In de regio Noord moeten we in verbinding zijn om te kunnen zorgen voor onze patiënten met een aandoening van het bewegingsapparaat, zodat ze tijdig en goed behandeld kunnen worden. We kijken naar heel de mens en stimuleren gezond gedrag, waarbij bewegen hoog op de agenda staat. Samenwerking met alle professionals, verzekeraars en patiënten is de enige weg om voor onze mensen te kunnen zorgen

Incidental imaging findings referred to a specialized sarcoma center:Frequency, determinants, and downstream healthcare costs

Objective To determine the frequency and factors associated with incidental imaging findings (incidentalomas) that are referred to a specialized sarcoma center and that eventually turn out to be benign or of low-risk malignant potential, and to assess their downstream healthcare costs. Materials and methods This study included all consecutive new patients that were referred to a specialized sarcoma center within a 7-month period. Results Of 221 patients that were included, 28 had an incidentaloma. Of these 28 incidentalomas, 23 were benign (n = 11) or of low-risk malignant potential (n = 12), corresponding to a frequency of 10.4% Utilization of conventional radiography (odds ratio [OR] = 6.538, P = 0.018) and CT (OR = 8.167, P = 0.012) was significantly more associated with the detection of benign or low-risk malignant potential incidentalomas than ultrasonography. The likelihood of detecting benign or low-risk malignant potential incidentalomas after MRI utilization was not significantly different from that after ultrasonography (P = 0.174). All other variables (including patient age and gender, history of malignancy, specialty by whom the lesion was initially detected, and lesion location) were not significantly associated with these incidentalomas. The 23 cases with an incidentaloma that turned out to be benign or of low-risk malignant potential resulted in a total of €42,707 ($49,552) downstream healthcare costs, with an average of €1857 ($2155) per case. Conclusion Incidentalomas that are referred to a specialized sarcoma center and that eventually prove to be benign or of low-risk malignant potential are common, are more frequently detected on conventional radiographs and CT, and cause relevant subsequent healthcare costs

Follow-Up in Bone Sarcoma Care:A Cross-Sectional European Study

Background. Follow-up of high-grade bone sarcoma patients with repeated radiological imaging aims at early detection of recurrent disease or distant metastasis. Repeated radiological imaging does expose (mostly young) patients to ionising radiation. At this point, it is not known whether frequent follow-up increases overall survival. Additionally, frequent follow-up subjects patients and families to psychological stress. This study aims to assess follow-up procedures in terms of frequency and type of imaging modalities in bone tumour centres across Europe for comparison and improvement of knowledge as a first step towards a more uniform approach towards bone sarcoma follow-up.Methods. Data were obtained through analysis of several follow-up protocols and a digital questionnaire returned by EMSOS members of bone tumour centres all across Europe. Results. All participating bone tumour centres attained a minimum follow-up period of ten years. National guidelines revealed variations in follow-up intervals and use of repeated imaging with ionising radiation. A local and a chest X-ray were obtained at 47.6% of the responding clinics at every follow-up patient visit.Conclusions. Variations were seen among European bone sarcoma centres with regards to follow-up intervals and use of repeated imaging. The majority of these expert centres follow existing international guidelines and find them sufficient as basis for a follow-up surveillance programme despite lack of evidence. Future research should aim towards evidence-based follow-up with focus on the effects of follow-up strategies on health outcomes, cost-effectiveness, and individualised follow-up algorithms.</p

Mechanical bone strength decreases considerably after microwave ablation-Exvivo and in-vivo analysis in sheep long bones

Background Bone metastases are on the rise due to longer survival of cancer patients. Local tumor control is required for pain relief. Microwave ablation (MWA) is a technique for minimally invasive local tumor treatment. Tumor tissue is destroyed by application of local hyperthermia to induce necrosis. Given the most common setting of palliative care, it is generally considered beneficial for patients to start mobilizing directly following treatment. No data on mechanical strength in long bones after MWA have been published so far. Materials and methods In- and ex-vivo experiments on sheep tibias were performed with MWA in various combinations of settings for time and power. During the in-vivo part sheep were sacrificed one or six weeks after ablation. Mechanical strength was examined with a three-point bending test for ablations in the diaphysis and with an indentation test for ablations in the metaphysis. Results MWA does not decrease mechanical strength in the diaphysis. In the metaphysis strength decreased up to 50% six weeks after ablation, which was not seen directly after ablation. Conclusion MWA appears to decrease mechanical strength in long bone metaphysis up to 50% after six weeks, however strength remains sufficient for direct mobilization. The time before normal strength is regained after the remodeling phase is not known.</p
