[Baropodometric analysis of the functional donor-site morbidity after gastrocnemius or soleus muscle-flap procedure]

The triceps surae muscle is a major donor-site for muscle-flap to cover soft-tissue defects of the leg. There are very limited datas on the functional donor-site morbidity in the literature. From a retrospective study on 14 patients, we realized a baropodometric analysis comparing the operated lower limb with the healthy non operated side and a functional evaluation by a questionary. The modified functional score of Kitatoka was good (87/100). Ninety percent of the patients were able to resume a professional activity and 2/3 to resume the sport. The baropodometric analysis did not show statistically significant difference of propulsion and absorption between the healthy side and the operated side, but a modification of the programming of the step. The absence of important functional donor-site morbidity is probably bound to a compensation of the remaining triceps surae muscles and/or to mechanisms of adaptation. Our study confirms the little functional donor-site morbidity of the partial triceps surae muscle-flap procedure. These flaps remain a good solution for the coverage of the soft-tissue defects of the leg.
