[Application of repairing tibia and soft tissue defect with free fibula combined tissue grafting]
1Center of Orthopedic Surgery, General Hospital of PLA of Lanzhou, Lanzhou, Gansu, P. R. China 730050.
Objective:
To investigate a good method for repairing the long bone defect of tibia combined with soft tissue defect.
Methods:
From 1988-1998, sixteen patients with long bone defect of tibia were admitted. There were 12 males, 4 females and aged from 16 to 45 years. The length of tibia defect ranged from 7 cm to 12 cm, the area of soft tissue defect ranged from 5 cm x 3 cm to 12 cm x 6 cm. Free fibula grafting was adopted in repairing. During operation, the two ends of fibular artery were anastomosised with the anterior tibial artery of the recipient, and the composited fibular flap were transplanted.
Results:
All grafted fibula unioned and the flap survived completely. Followed up for 6 to 111 months, 14 patients acquired the normal function while the other 2 patients received arthrodesis of the tibial-talus joint. In all the 16 patients, the unstable ankle joint could not be observed.
Conclusion:
The modified method is characterized by the clear anatomy, the less blood loss and the reduced operation time. Meanwhile, the blood supply of the grafted fibula can be monitored.
