To explore plantar pressure measurement system in treating the first ray hypermobility. From June 2013 to January 2014, 16 female patients (20 feet) with hallux valgus with unstable of the first sequence were treated by first tarsometatarsal joint fusion, aged from 42 to 52 years old with an average of(46.5±2.9) years old, the course of disease was from 3 to 5 years. Twenty healthy female(20 feet) were chosen as control group, and single side were only choose, aged from 41 to 55 years old with an average of(46.8±4.5) years old. Preoperative and postoperative AOFAS score was used to evaluate feet function. Plantar pressure measurement system were applied to compare peak value of the dynamic pressure and impulse indicators of affected feet and control normal feet from the first to the fifth head of metatarsal bone. All patients were followed up from 24 to 30 months with an average of 27.4 months. Hallux valgus deformity of affected feet were corrected, pain and swelling of the second head of metatarsal bone wer
