摘要
Background: The Bridle procedure restores active ankle dorsiflexion through a tri-tendon anastomosis of the tibialis posterior, transferred to the dorsum of the foot, with the peroneus longus and tibialis anterior tendon. Inter-segmental foot motion after the Bridle procedure has not been measured. The purpose of this study is to report kinetic and kinematic variables during walking and heel rise in patients after the Bridle procedure. Methods: 18 Bridle and 10 control participants were studied. Walking and heel rise kinetic and kinematic variables were collected and compared using an ANOVA. Findings: During walking the Bridle group, compared with controls, had reduced ankle power at push-off 123 (SD 0.7) W/kg, 3.4 (SD 0.6) W/kg, respectively, P < .011, less hallux extension during swing [-13 (SD 7)degrees, 15 (SD 6)degrees, respectively, P < .01] and slightly less ankle dorsiflexion during swing [6 (SD 4)degrees, 9 (SD 2)degrees, respectively, P = .03]. During heel rise the Bridle group had 4 (SD 6)degrees of forefoot on hindfoot dorsiflexion compared to 8 (SD 3)degrees of plantarflexion in the controls (P < .01). Interpretation: This study provides evidence that the Bridle procedure restores the majority of dorsiflexion motion during swing. However, plantarflexor function during push-off and hallux extension during swing were reduced during walking in the Bridle group. Abnormal mid-tarsal joint motion, forefoot on hindfoot dorsiflexion instead of plantarflexion, was identified in the Bridle group during the more challenging heel rise task Intervention after the Bridle procedure must maximize ankle plantarflexor function and midfoot motion should be examined during challenging tasks.
