Finite element analysis of the flexor digitorum profundus tendon during a passive rehabilitation protocol

The present study aims to create a patient-specific hand model simulate the passive rehabilitation on index finger, quantifying flexor digitorum profundus (FDP) tendon excursion and stress experienced during simulated flexion. computational used in this analysis was created from an unknown patient dataset available Embodi3d online library. segmentation, three-dimensional reconstruction, modeling of structures involved were performed using Materialise Mimics Rhino3D. FDP values calculated ANSYS environment. Based finite-element simulation, presents 10.1 mm postoperative highest-stress observed between pulleys-FDP contact surfaces. In particular, pulley A1 exhibited maximum principal with 58.7 MPa. A3 showed same distribution pattern that Pulley, but lowest values. Tendon obtained is consistent results reported literature, which vary 8 11 mm. found explain importance mechanism keeping attached finger bone range motion experienced. silico proposed may potentially be assessment new medical device proposals field reconstructive surgery.
