This complex foot deformity involves changes of the ankle and foot that affect the entire lower extremity and gait cycle. Maintaining the longitudinal arch of the foot involves dynamic and static structures. The aim of this study is to evaluate the efficacy of use of calcaneal osteotomy with or without tendon transfer for management of early stages of adult acquired flat foot to illustrate advantages and disadvantages of this procedure in progress of the disease. A prospective study on Twenty patients with twenty feet 20 patients older than 18 years with adult acquired flexible flatfoot stage 2. Patients were evaluated pre and postoperatively using AOFAS score. Patients followed up for a minimum of 6 month with the mean follow up period was 9.90 month (range 6- 15 month). The duration of symptoms before the operation ranged from 11 month to 18 month with an average 13.55 (SD was 2.305). AOFAS score improved from mean 53.05 ± 4.904 preoperative to 88.80 ± 3.205 postoperatively. Clinically, all patients have satisfactory level of function.radiologically, the mean AP radiographs improved from 18.50 ± 8.036 preoperatively to 6.85 ± 5.112 postoperatively ER -
