The anteroposterior projectionof the foot, utilized to examine the foot disease in the past was referred as to the freely-stressed method. However, most of the patients on suspicion of Hallux Valgus get pains while standing with weight-bearing. Additionally, the patients' real conditions can not be diagnosed without standing. it is helpful for us to apply both the foot weight-bearing and the foot non weight-bearing so as to probe the individual difference between the HVA and the IMA 1(superscript * intermetatarsal angle and further to provide the informative resources concerning the assessment of performing surgery operation. The study include 40 patients who we having Hallux Valgus of different degree, The findings have revealed the significant difference among 40 patients after the method-weight-bearing AP of the foot projection given.
