This study compares static measurement in clinical and radiologic evaluation for assessment of pes planus, to evaluates whether it leads to abnormal gait pattern. 13 children with pes planus were selected. Femoral anteversion, internal and external rotation, thighâ€“foot angle (TFA), and resting calcaneal stance position (RCSP) were measured, as well as talo-calcaneal angle (TCA), talometatarsal angle (TMA), calcaneal pitch, and forefoot adduction on simple X-ray, and femoral anteversion, tibial torsion and rotation on computed tomography (CT). Then a 3-D gait analysis was performed and the correlation between all data was assessed.
It concludes that TMA was the factor most related to degree of calcaneal valgus on physical exam and that larger TCA was responsible for decreased maximal external rotation and increased maximal internal rotation in gait cycle.
