Abstract
Background
The aim of our study was to compare spatiotemporal parameters and lower limb and pelvis kinematics during the walking in patients with hallux valgus before and after surgery and in relation to a control group.
Methods
Seventeen females with hallux valgus, who underwent first metatarsal osteotomy, constituted our experimental group. The control group consisted of thirteen females. Kinematic data during walking were obtained using the Vicon MX system.
Findings
Our results showed that hallux valgus before surgery affects spatiotemporal parameters and lower limb and pelvis kinematics during walking. Hallux valgus surgery further increased the differences that were present before surgery. Specifically after hallux valgus surgery, the walking speed decreased even more (p = 0.09, η2 = 0.19) while step time increased (p = 0.002, η2 = 0.44) on both legs. The maximum ankle plantar flexion of the operated leg during toe-off decreased to a greater extend (p = 0.03, η2 = 0.26). The asymmetry in the hip and the pelvis movements in the frontal plane (present preoperatively) persisted after surgery.
Interpretation
Hallux valgus is not an isolated problem of the first ray, which could be just surgically addressed by correcting the foot's alignment. It is a long-term progressive malfunction of the foot affecting the entire kinematic chain of the lower extremity.
