Femoral fractures in amputation stump are challenging injuries to manage. The authors describe a case of a 51-year-old patient with a right above knee amputation, who had a right hip femoral neck fracture. In this technical note, we describe a technical and surgical procedure with intraoperative tips and tricks, in which we use commonly available materials, for the safe management in such clinical situations.
Omarthrose bilatérale de l’épaule sur ostéonécrose est une pathologie rarement traitée dans la littérature. La présence de cette pathologie chez deux sœurs gémellaires n'est jamais décrite. Sa prise en charge chirurgicale représente un défi et nécessite un chirurgien orthopédique expérimenté en chirurgie du membre supérieur. Nous présentent deux sœurs gémellaires qui avaient une omarthrose bilatérale de l’épaule sur ostéonécrose, qui ont été traités dans notre département par prothèse inversée. La planification préopératoire a été réalisée par une équipe de chirurgiennes entrainées. Globalement nos résultats (cliniques et radiologiques) immédiats, moyen terme et au dernier recul étaient satisfaisants. Le but de notre travail est d'attirer l'attention sur cette association rare et de discuter sa prise en charge thérapeutique.
Objective - to study the nature and prevalence of pathological changes in the cartilage of the trachea depending on the duration of intubation according to the results of pathomorphological studies. Materials and methods. Pathomorphological study of cartilage of the anterior tracheal wall was carried out on 37 patients at different times of mechanical ventilation. Depending on the timing of the ventilator before the tracheostomy, all patients were divided into three groups. In 10 people, the duration of ventilation until tracheostomy was no more than 3 days, in 15 people - 4 -7 days and in 12 people - more than 7 days. Results. On the 1st day of mechanical ventilation, dystrophic changes are determined, with the loss of cartilage cells. On the 2nd day of mechanical ventilation in the cartilage of the trachea significant dystrophic changes with pycnosis of the nuclei in chondrocytes were revealed. By the third day of mechanical ventilation, detachment of perichondria occurred, the surface of cartilage lacking perichondria was usurized, covered with fibrinous overlays, the cartilage no longer contained cartilage cells; by the 7th day of mechanical ventilation, deeper dystrophic and destructive changes were revealed in the tracheal cartilages - there was no perichondria, the cartilage surface was usurized, foci of chondronecrosis were observed in the areas adjacent to the damaged perichondria; by the tenth days of mechanical ventilation, the pathomorphological picture indicates the death of the cartilage and its replacement with granulation tissue, the presence of regeneration processes, expressed in focal proliferation of chondrocytes, thickening and fibrosis of the perichondria, the appearance and sequestration of dead cartilage. Conclusion. The severity of pathomorphological changes in the cartilage of the trachea due to the duration of intubation
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
