[An experimental study of the implantation of an epitendineum-109 human hair artificial tendon complex in rabbits].

OBJECTIVE: To study the feasibility of in vivo implantation of an epitendineum-109 human hair (109HH) artificial tendon composite. METHODS: An absorbable epitendineum-109HH artificial tendon complex was implanted into rabbits to observe its changes at different time points. In control groups, 109HH artificial tendons or the artificial tendon-Dacron complex were implanted instead. RESULTS AND CONCLUSION: and Conclusion The epitendieum-109HH artificial tendon complex was gradually but finally completely absorbed by the surrounding tissues to be replaced by normal tendon without conglutination or scar formation, approving the feasibility of the implantation of epitendineum-109 human hair artificial tendon complex in vivo.

[Surgical correction of leg-length discrepancy using the method of leg-length equalization: report of 4 cases].

OBJECTIVE: To describe a method of leg-length equalization for the correction of leg-length discrepancy. METHOD: Osteotomy and femur inlay was performed in 4 cases. RESULT: Smooth bone healing was achieved within one year postoperatively and the function of the repaired legs was satisfactory. Transiently limited flexion extension movement of both knees was observed during the operation and recovered normal after 3 months. CONCLUSION: Leg-length equalization is a safe method for leg-length discrepancy.
