Objective: To investigate the effect of free abdominal flap in repairing soft tissue defects of the foot. Methods: From 2011.10 to 2017.11, there were 5 patients whose foot had soft tissue defect, in order to repairing, we had to do debridment at the early time, then made the anterior iliac artery or the inferior epigastric artery as the axial vessel. Results: After the flap transplantation there was no vascular crisis in the 5 patients , followed up for 3 months to 1 years, the blood supply, texture, elasticity and the foot was well in shape and feeling, the patients were satisfied, and the feet were functionally normal. Conclusions The application of free abdominal skin flap covers the soft tissue defect of the foot, the wound surface, the blood vessel the donor site is consistent, the flap is easy to prepare, and the area can be sutured directly, this is an effective treatment method.

Characteristics of two major categories of RA equipment which defined in the standard are interpreted firstly. Few representative RA equipment in current market and their key product features are introduced. Then, classifications of different indexes of spatial positioning accuracy are declared, the difficulties of performing testing process on each indexes are further explained. Meanwhile, different kinds of three dimensional coordinate measuring equipment that are cutting edge at present stage are introduced with their main methods of use explained. According to characteristics of three dimensional coordinate measuring equipment on the market, proper measuring equipment for testing certain index of spatial positioning accuracy and corresponding experiment method are introduced.
