Summary
The authors present a biomechanical study of tendon behavior after primary suturing and early active mobilization [1]. In this animal study (23 specimens), three types of sutures are compared using 2 biomechanical parameters: the load at rupture (R), and Young's modulus of elasticity (E). The authors show that early mobilization does not compromise the final strength of a tendon. Moreover, early mobilization confers the biomechanical characteristics of resistance and elasticity more closely akin to those of the normal tendon. Pathoanatomical examinations confirm the fibroelastic reaction of cicatrization and the mechanical role of mobilization in the orientation of newly formed tendon fibers.
Résumé
Les auteurs présentent une étude biomécanique du comportement tendineux après suture primaire et mobilisation active immédiate [1]. Il s'agit d'une expérimentation animale (23 cas) où trois types de suture sont analysés grâce à 2 paramètres biomécaniques: la charge à la rupture (R) et le module délasticité de Young (E). Ils démontrent que la mobilisation précoce, non seulement, ne compromet pas la solidité finale du tendon, mais lui confère des caractères biomécaniques de résistance et d'élasticité plus proches de ceux du tendon normal. L'étude anatomopathologique confirme la réaction fibroblastique de cicatrisation et le rôle mécanique de la mobilisation dans l'orientation fibrillaire.
