[Transferring of the pedicled second metatarsal base for repairing bone defect of lateral malleolus].

OBJECTIVE

To study the method and effect of transferring the pedicled second metatarsal base for repairing bone defect of lateral malleolus.

METHODS

Thirty lower limb specimens were anatomized to observe the morphology, structure and blood supply of the second metatarsal bone. Then transferring of the pedicled second metatarsal base was designed and used in 6 patients clinically. All cases were male, aged from 24 to 48 years old, and the area of bone defect was 3-4 cm.

RESULTS

Followed up for 3-11 months, all patients healed primarily both in donor and recipient sites. There were excellent results in 4 cases and good results in 2 cases. The morphology and function of the malleoli were satisfactory.

CONCLUSION

Transferring of the pedicled second metatarsal base for repairing bone defect of lateral malleolus is an effective and reliable operative method.
