This study describes the changes in hip and pelvic kinematics in 19 trans-femoral
amputees, who were treated with an osseointegrated trans-femoral prosthesis.
Patients were studied with 3-dimensional gait analysis, walking with socket
prosthesis within two days before the osseointergration procedure. The
post-operative gait analysis was carried out at the 2 year follow-up visit.
Fifty-seven; age-, side- and gender-matched healthy subjects served as controls.
Post-operative data showed that patients who had an osseointegrated transfemoral
prosthesis increased their hip extension by 7.3 degrees (p=0.007), changing from
-2.6 degrees (range -13.4 degrees to 10.7 degrees ) to -9.9 degrees (range -29.4
degrees to 5 degrees ). Moreover, the pre-operative anterior pelvic tilt was
reduced by 4.0 degrees (p=0.016), changing from 21.7 degrees (range 11.9-34.8
degrees ) to 17.7 degrees (range 5.5-25.7 degrees ). Values for hip extension and
pelvic tilt changed toward those of controls. These results confirm that patients
treated with osseointegrated trans-femoral prosthesis encounter significant
changes of their kinematic pattern in terms of hip extension and anterior pelvic
tilt. Even though the changes were moderate they may, in the long-term have a
positive influence on low-back biomechanics and could contribute to reducing the
risk of further problems with low back pain.
