The aim was to investigate with a multi-segmental foot model the kinetic and kinematic in patients with a hallux rigidus, before and after different type of surgery.
None of the patients received surgery BECAUSE of the study. We have only performed motion analysis in patients, who were already scheduled for one of the described type of surgery (prospective group) or who already previously received one the type of surgery (retrospective group).
Study Type
OBSERVATIONAL
Enrollment
56
3D Motion analysis with retroflective markers on the skin (Vicon camera system) of the foot and lower leg (kinematics), walking over force plate (kinetics) and pressure plates (plantar pressure distribution).
Motion Analysis Laboratory of the Department of Orthopedics, Trauma Surgery and Spinal Cord Injury, University Hospital Heidelberg
Heidelberg, Germany
Change of hallux range of motion
Time frame: baseline (=1 day before surgery) and 1 y. after surgery for the prospective groups, more than one year after surgery for the retrospective groups
