“…Furthermore, weight-dependent changes of the soft tissue of the stump can lead to an insufficient attachment of the prothesis (Hoffmeister et al, 2017 ; Beck et al, 2019 ); but there are optional methods to attach the prosthetic leg to the tight stump. The treatment of amputations with transcutaneous osseointegrated prosthetic systems (TOPS) has been established throughout the last two decades in Germany, Sweden, the Netherlands, and Australia (Aschoff et al, 2009 , 2010 ; Juhnke and Aschoff, 2015 ; Juhnke et al, 2015 ; Aschoff, 2017a , b ; Pospiech et al, 2020 ). Compared to the most frequently used “socket suspension” method for prosthetic limb attachment, this method offers a variety of new options (Hagberg et al, 2005 ; Aschoff et al, 2009 ; Frossard et al, 2009 ; Van de Meent et al, 2013 ; Hoffmeister et al, 2017 ; Al Muderis et al, 2018 ).…”
