Objective: To report the experience in the use of unreamed interlocking intramedullary nails.
Method: From 1995 to 1997, 54 tibial and fibular fractures were treated with unreamed interlocking intramedullary nails they included open fractures (9 cases) and close fractures (45).
Result: All fractures healed within 6 months and showed good knee and ankle joint functions. Slight postoperation infection was found in one of the open fractures. Incomplete injury of peroneal nerve was noted in 1 case.
Conclusion: Unreamed interlocking intramedullary nail can be used to treat diaphyseal fractures effectively. It can protect the soft tissue envelope around the fracture and prerent local blood supply from further damaginge.
