Abstract

• For the treatment of tibial shaft fracures interlocking intramedullary nailing has been used widely. Recently choosing between reamed or unreamed interlocking nailing for closed tibial shaft fracture is still controversial. The purpose of this study is to evaluate the results and complications of unreamed interlocking nailing for closed tibial shaft fractures. We reviewed 28 closed tibial shaft fractures that were treated with unreamed static medullary nailing from May 1993 to December 1996 at the Deparment of Orthopaedic surgery, Pohang St. Mary's Hospital. The results were as follows 1. In all 28 cases, union of the fracture was achieved at average 19.6 weeks and tere was no malunion. 2. We performed additional procedures in 4 cases(14.3%) for union : autogenous iliac bone graft in 1 case(3.5%) that was unstable segmental fracture and dynamization in 3 cases(10.7%) 3. There was breakage of distal locking screw in 1 case but no breakage of intramedullary nail.
• Key words: Tibia, Closed shaft fracture, Unreamed intramedullary nailng
