1. In an end-result study of 458 tendon transplantations, it was found that 85 per cent. of these operations gave satisfactory results.
2. Tendon transplantations in children over eight years of age with post-poliomyelitic deformities yielded better results than in younger patients.
3. Of the deformities in post-poliomyelitis, the varus foot gave the best results.
4. In tendon transplantations in the post-poliomyelitic cases, the larger muscles gave the better results.
5. A convalescent period of over two years after the acute phase of anterior poliomyelitis did not increase the number of satisfactory tendon transplantations.
6. Stabilization increased the number of satisfactory tendon transplantations. In 19 per cent. of the cases in which tendon transplantations were done without stabilization, secondary stabilizations were necessary.
7. The type of insertion of the transplant should be simple and expedient. A method of bone tunnel with external suture is recommended.
8. An analysis of the causes of failure to obtain perfect results showed that errors in surgical judgment were more frequent than errors in surgical skill.
9. In the cases of congenital equinovarus, good results were fairly evenly distributed in the age groups. However, the poor and unsatisfactory results occurred in the children under six years.
10. Transplantation of the tendon of the tibialis anterior to the middorsum of the foot was the most successful procedure in cases of congenital equinovarus.
11. Transplantation of tendons in cases of cerebral spastic paralysis and in those of Charcot-Marie-Tooth peroneal paralysis was not efficient.
