Aims
The purpose of this study was to analyse the biomechanics of
walking, through the ground reaction forces (GRF) measured, after
first metatarsal osteotomy or metatarsophalangeal joint (MTP) arthrodesis.
Patients and Methods
A total of 19 patients underwent a Scarf osteotomy (50.3 years,
standard deviation (sd) 12.3) and 18 underwent an arthrodesis
(56.2 years, sd 6.5). Clinical and radiographical data
as well as the American Orthopaedic Foot and Ankle Society (AOFAS)
scores were determined. GRF were measured using an instrumented
treadmill. A two-way model of analysis of variance (ANOVA) was used
to determine the effects of surgery on biomechanical parameters
of walking, particularly propulsion.
