Dear List,
I have a 24 y.o. male Iraqi veteran amputee that is extremely active and
wants to ride a standard racing bike. The patient has a left transtibial
amputation and a right transfemoral amputation. The problem I am having is
with the transfemoral side. The patient's current ambulatory/running
prosthesis is ischial containment with flexible inner/external frame. The
patient's limb is suspended with a seal-in liner and Coyote summit lock.
The problem I am experiencing is that the patient goes into 120-130 degrees
of flexion at the hip when he is in his tuck position in the bike and the
socket is breaking suction in turn pulling on the and summit lock to the
point that the liner almost wants to come off. The patient's residual limb
length is only 7 1/2 . I have duplicated his everyday prosthesis and cut
it down to be almost a plug fit. The medial wall was lowered to accommodate
the bicycle seat and I brought the anterior trim line very low to not
interfere when the patient ranges into full hip flexion. The pedal lengths
and seat height seem appropriate. Any suggestions would be greatly
appreciated. Thanks.
