Abstract  

Avascular necrosis of human femoral head (ANFH) causes incongruity in the joint that leads to disability in patients requires total hip arthroplasty (THA). Several etiological factors of ANFH have been proposed in the literature but there are cases of idiopathic origin. We observed macroscopic variation in quality of the subcutaneous fat tissue in patients with ANFH compared to patients with osteoarthritis or hip fracture during THA procedures. The samples were analysed by histology, gas chromatography (GC) and differential scanning calorimetry (DSC). Conclusion: the alteration in the fatty acid profile did not cause histological changes, however we could detect biochemical changes using DSC and GC.

Abstract  

The osteonecrosis or avascular necrosis of the antero-superior part of the human femoral head (ANFH) often causes incongruity in the hip joint and leads to severe pain and disability in middle aged patients. This abnormality often requires surgical intervention, mainly total hip arthroplasty (THA). The possible pathomechanisms of ANFH are fat embolism, arterial occlusion, fatty necrosis of osteocytes and intraosseous hypertension. Factors have been proposed in the literature that can lead to this condition are alcohol abuse, steroid therapy, metabolic changes, dyslipidaemia. In some case we can not verify any factor; these are the so called idiopathic ANFH cases. We observed macroscopic variation in colour and consistency of the subcutaneous fat tissue in patients with ANFH compared to osteoarthritis or hip fracture during THA procedures. Subcutaneous fat tissues during THA from a patient with ANFH due to alcohol abuse were compared with an otherwise healthy patient who underwent surgery due to traumatic hip fracture. No histological changes were notified in the size; shape of adipocytes and in the cells of the septae of the connective tissue. Gas chromatography showed that the patient with alcoholic ANFH had less long chain fatty acids. DSC revealed, that in case of non-necrotic sample as a reference, during heating between 0–100°C two separable transitions are with T m=5.7 and 9.9°C, total ΔH= −20.8 J g−1. In −20–100°C range endotherms with T m= −10.9 and 4.95°C, total ΔH= −75.8 J g−1 could be detected. In case of alcohol-induced avascular necrosis we have found endotherms between 0–100°C with: T m=7.3°C, total ΔH= −26.9 J g−1, and heating between −20–100°C: T m= −0.25°C, total ΔH= −103.3 J g−1 thermal parameters. The alteration in the fatty acid profile did not cause histological changes, but we were able to detect it with analytical methods e.g. DSC and gas chromatography.

A szerzők ritka veleszületett vérzékenységben, XI-es faktorhiányban szenvedő nőbetegek ortopéd sebészeti, illetve traumatológiai műtét után jelentkező, keringésmegingást okozó vérzéses szövődményének kezelését, illetve a vérzéses szövődmény kivédését ismertetik aktivált, rekombinált VII-faktor (NovoSeven ® , Novo Nordisk, Bagsvaerd, Denmark) alkalmazásával. Az első esetben előrehaladott, bal csípőízületi arthrosis miatt csípőízületi teljes arthroplasticát végeztek. Az ismert vérzékenység tükrében, a friss fagyasztott plazma adása ellenére, súlyos fokú utóvérzés lépett fel. A szerzők ismertetik a műtét után kialakult vérzéses epizódok időbeli dinamikáját, az újbóli feltárás dilemmáját és az alkalmazott aktivált rekombinált VII-faktor- (rFVIIa-) terápiával szerzett kedvező tapasztalataikat. A második esetben egy ismerten FXI-hiányos beteg esés során elszenvedett jobb oldali pertrochantertörésének műtéti megoldását ismertetik. A beteg korábbi műtétei során jelentős vérzékenységet tapasztaltak, ami az alkalmazott friss fagyasztott plazma adásával nehezen volt uralható, ezért a vérzéses szövődmény elkerülése érdekében a műtétet rVIIa-faktor védelmében végezték.
