Abstract:
Objective To investigate the effect of the different rehabilitation training method on the first ray of postoperative hallux valgus (HV). Methods Based on medical images of HV patient, a comprehensive three-dimensional finite element model of HV foot was established, including bones, sesamoid, cartilage, ligaments, soft tissues, Achilles tendon. The passive/active plantar flexion and dorsal flexion as well as standing were simulated to investigate the biomechanical behavior of distal osteotomy fragment of the postoperative HV. Results The stress distribution on distal osteotomy fragment during passive training was more uniform, and the peak stress (7.78 MPa) was greater than that during stance phase and active training. The distal osteotomy fragment displacement during passive training (0.98 mm) in anterior-posterior direction was greater than that during stance phase (0.69 mm) and active training (0.38 mm). Conclusions The passive training could promote the contact of osteotomy surface and reduce the healing time of osteotomy, which would be beneficial for rehabilitation of postoperative HV.
