Hagen Fritzsche's research while affiliated with Universitätsklinikum Carl Gustav Carus Dresden and other places

... The operation time was 502 ± 159 min, and a bifurcated graft (74.7%) and a physician-made pericardium graft (61.3%) were used most frequently. Additional procedures included renal cold perfusion and partial left heart bypass for distal and/or selective perfusion (described previously) [20]. Of 31 additional simultaneous procedures, intestinal resection was most frequent (Table 3). ...

... Чаще всего мягкотканный компонент представлен несвободным паховым лоскутом, а в качестве костной основы используют фрагмент гребня подвздошной кости [17,18,19]. Описаны также единичные случаи кожно-костной реконструкции с применением других кровоснабжаемых сложных комплексов тканей, которые поз воляют восстановить палец путем выполнения одного вмешательства: свободного кожно-костного латерального лоскута плеча [20], островкового кожно-костного комплекса тканей на второй тыльной пястной артерии [21], островкового кожно-костного лоскута предплечья на задней межкостной артерии [22]. ...

... Only 4 cases of large articulation dislocation (5.6 %) and 1 of early IPD of unmentioned etiology (1.4 %) out of 71 implants were described. In addition, Bellova et al. are the only ones that recorded one case of a dissociation at the cementcup interface (33). ...

... In diesen Fällen ist den palliativen Patienten eine tumorendoprothetische Versorgung in zementierter Technik, gegebenenfalls mit langen Schäften und speziellen Abstützpfannen anzubieten. Die Möglichkeit der postoperativen Vollbelastung stellt einen großen Vorteil dieses Versorgungsprinzips dar [3,4,[6][7][8]. ...

... J Wegrzyn et al have described this with a dual mobility cup as it ensures the greatest construct strength. [4][5][6][7][8] Screw removal was performed to avoid the potential problem of a retained screw getting buried in cement in case a further revision is required. The holes of the multihole shell were curetted such as to act as anchoring holes for the cement to increase the fixation strength in contrast to roughening the inside of a smooth shell with a burr as roughening may create particulate debris as described by J Wegrzyn et al, Challagan et al and Boner et al. [4][5][6]9 This technique proves to be particularly beneficial for high-risk or low-demand patients. ...

... All tumours with slightest suspicion of malignancy require histopathological proof by biopsy (2,7,16). To prevent wrong indications and avoidable complications, biopsy must be planned by an interdisciplinary tumour board in a designated tumour centre according to strict oncosurgical guidelines (1,3,4,5,11,18). In case of small and in radiomorphologically benign tumours, this can be conducted as an excisional biopsy (6). ...

... По сравнению с традиционным первичным эндопротезированием тазобедренного сустава результаты установки онкологических эндопротезов с замещением дефекта проксимального конца бедренной кости менее благоприятны. За исключением прогрессирования основного заболевания, чаще всего к повторным операциям ведут инфекционные осложнения, вывихи, асептическое расшатывание ножки эндопротеза [1]. Известно, что при перипротезной инфекции (ППИ) в организме больного формируется как минимум три резервуара микробов: абсцессы в мягких тканях и костном мозге, микробная биопленка на поверхности имплантатов, колонизированные костные канальцы. ...

... On the other hand, these muscles provided superior protection of the prosthesis against dislocation and hip pain during activity. Dislocation is the most prominent complication of tumor prosthesis [17]. In our study, we discovered that the eggshell procedure significantly decreased the incidence of dislocation as well as hip pain which is a characteristic complication of hip arthroplasty. ...

... Tumors at the foot and ankle are rare and constitute about 4%-5% of all musculoskeletal tumors (Rammelt et al., 2020;Ruggieri et al., 2014;Toepfer et al., 2018). Benign lesions occur 200 times more frequently than malignant ones (sarcomas that arise in foot and ankle are only about 1%-2% of all sarcoma), and bone tumors affecting the foot and the ankle constitute approximately 3% of all cases (Rammelt et al., 2020;Ruggieri et al., 2014;Salipas et al., 2014;Temple et al., 2001). ...

... In principle, it is recommended that patients with suspicious lesions are examined and treated in tumour reference centers (1,2). Unplanned surgery often results in the need for more aggressive surgery and/or adjuvant radiotherapy and may adversely affect oncologic and functional outcomes (2,3,4,5). The treatment of benign tumours in the foot and ankle region distinctly differs from that of malignant ones. ...
