abstract = {The Lapidus arthrodesis is a common surgical intervention
for hallux valgus aimed primarily at improving pain and
functionality in the affected foot. Instrumented motion
analysis provides the opportunity to collect objective data
on movement behavior. The study aims to examine the extent
to which fusion in the first tarsometatarsal joint affects
the remaining joints of the lower extremity. In addition,
MCID values for specific parameters are to be calculated,
providing an objective assessment of functionality and
patient satisfaction three months postoperatively.
Therefore, 20 patients were examined pre- and
postoperatively three months after Lapidus arthrodesis using
instrumented motion analysis. The inertial sensor system MTw
Awinda was used for the motion analysis of the lower
extremity during walking and stair climbing. Specifically,
spatiotemporal and kinematic gait parameters of the ankle,
knee, and hip joints in the sagittal plane were analyzed.
MCID values for the VAS score and the FAAM-G were also
obtained for all patients, allowing for a comparison and
correlation with the results of the gait analysis
parameters.The results of this study confirmed the
hypothesis that Lapidus arthrodesis has an impact on the
biomechanics of the joints throughout the lower extremity
three months postoperatively. This is demonstrated in
kinematic parameters, such as reduced walking speed, as well
as spatiotemporal parameters, indicating a reduced range of
motion in all joints, particularly the ankle. In addition to
the altered biomechanics, there is also a decrease in
functionality for those patients how underwent a marginal
reduction of pain.Nevertheless, this finding is of
significant interest as it suggests impaired functionality
of the foot due to pain. When compared to existing
literature, our results align with previous findings
regarding altered spatiotemporal gait parameters and MCID
values for VAS and FAAM-G. Furthermore, objective MCID
values were calculated for specific clinical situations
using various methods and for different gait analysis
parameters for the first time. However, determining these
values based on larger cohorts is necessary for clinical
application.},
