This prospective study was carried out in the plastic and reconstructive surgery department of Kassab's hospital in Tunis and the hospital of Monastir (Tunisa) during the sacrifice day (Aïd el kebir). The study involved 50 patients. Our purpose was to identify the injuries of the hand occurring during this religions festival. The average age of patients was 39 years with sex ratio of 1.17. All socials and occupational sectors were affected. The lesions concern the dorsal face of non dominant hand (72%) with a peak in the frequency for the thumb (40%) and the index (37%). Extensor system of the radial finger on the non dominant hand was the main delicate element witch is most exposed during such festival. The thumb is being worthy of special mention, for it is the most serious lesions (amputation 10%) The lesions of flexor tendons are generally associated with nerve and vascular injury. 46% of patients had to undergo surgery.
