Introduction – Disarticulation through the midtarsal joints was first performed by Francois Chopart in the late 18th century. Chopart amputation was used for the treatment of diabetic gangrene, frost bite, unsalvageable injuries and tumours of the foot. However, it soon fell into disrepute due to the development of progressive equinovarus deformity of the stump, painful callosities and skin breakdown on the anterior aspect of the calcaneum, and poor prosthetic fitting. Soft tissue coverage is of great concern while performing chopart amputation in traumatic foot. Inadequate soft tissue coverage may lead to skin breakdown on anterior aspect of the stump and increase further morbidity of the patient. Material and method – This is a Retrospective study involving 16 patients with unsalvageable foot trauma with intact heel pad operated at Dr Radhakrishnan Govt. Medical College Hamirpur ,Dr Rajendera Prasad Govt. Medical College Tanda at Kangra and Shri Lal Bahadur Shastri Govt. Medical College Mandi at Nerchowk in Himachal Pradesh. Chopart amputation was done in all the patients with sacrificing head of talus to achieve adequate soft tissue coverage. Lieberman et al classification of outcome following Chopart’s amputation was used to access the outcome. Results: Out of 16 patients, we have excellent outcome in 12 patients, Good out come in three patients and fair in one patient Conclusion – Modified Chopart amputation gives good functional outcome in non salvageable foot injuries. Excising the head of talus helped to achieve adequate soft tissue coverage and prevent breakdown of the skin over the anterior aspect of the calcaneum. Preserving the heel dramatically improve the gait of the patients and overall quality of life
