I did a thesis of treatment with muscle pedicle graft in fracture neck of femur for Master degree of orthopaedics in 1997. Then I did a thesis of treatment with flexor tendon graft in old flexor tendon injury of fingers for Docterate degree of orthopaedics in 2002. Then I studied the management of necrotizing fasciitis of extemities and published a review article in MSU University Jounal, Vol 22, No(2), 2024. Now I am studying the role of negative pressure wound therapy in the extremities. Now I am also studying the effectiveness of case-based learning in mediacal education. My main interest is the traumatology.
