SARDENBERG, Trajano et al. Mechanical comparative analysis of three different types of sutures in different dimensions tendons: experimental study. Acta ortop. bras. [online]. 2002, vol.10, n.3, pp. 35-41. ISSN 1809-4406. http://dx.doi.org/10.1590/S1413-78522002000300005.
The aim of this experimental investigation was study of mechanical profile of three kinds of suture, between tendons with different dimensions. Were utilized 21 mongrel dogs ( 11males, 10 females) of wich were obtained the tendon comum flexor and tendon tibial cranial of both pelvic limbs. After the dissection of the tendons, suture was done, seven animal per group. The tendons utilized allways were from the right limb and from the left limb side utilized as control. After the suture, we performed axial traction tests, rate level of 30mm /min, using special jaws. After the test the machine's program informed the values of ultimate load, elongation and strain, and load elongation diagram. The results were submite to statistical study, that showed no difference between the technics utilized. The values of suture groups were smaller than the control, for ultimate load, and higher for elongation and strain.
