Abstract
Materials and methods Thirty children (37 feet) were evaluated preand 2.0 ±0.6 yrs (range: 0.8 to 2.9) post-op following ATT transfer. Foot progression angle (FPA) and sagittal ankle kinematics were assessed using a VICON system. Plantar pressures were collected using the Emed ST Platform. Representative trials were chosen for each subject for gait and plantar pressures. Plantar pressures were divided into medial and lateral hindfoot, midfoot and forefoot. Variables included: contact time (CT%), contact area (CA% total), peak pressure (PP), hindfoot-forefoot angle [2], deviation of the center-of-pressure (COP) line and region of initial contact. Twenty age matched controls were used for comparison.
Highlights
Relapses following nonoperative treatment for clubfoot occur in 29-37% of feet following initial correction [1]
The forefoot shows the most change with a significant decrease in CA%, CT% and peak pressure (PP) in the lateral forefoot, redistributed to the first metatarsal for more even distribution through the foot
Initial contact was not different from normal post-op and no change was seen in the deviation of the COP line or hindfoot-forefoot angle (p=0.8025) post-op
Summary
The purpose of this study was to assess kinematic and plantar pressure changes following an ATT transfer
