下腿骨開放骨折発生頻度と治療成績

Abstract

We retrospectively reviewed the records of patients with tibia fractures treated between May 1992 and May 1997. There were 83 tibial fractures; 49 closed and 34 open. The ratio of open fracture was 41% (34/83), 25% in the tibial plateau fractures, and 60% in the tibial shaft fractures. Most of the open fractures were the result of high-energy trauma (90%). Thirty percent of the closed fracture were the result of low-energy trauma. The average period to roentgenographic union was 5.4 months for closed fractures. The time to union in open fractures was 7.3 months. Infection occurred in 4 of the 34 open fractures. By Gustilo grade, deep infection occurred in none of the 17 Grade I, II fractures (0%); one of the 12 Grade III-A fractures (8.3%); and one of the 5 Grade III-B fractures (20%). In the statistical evaluation of the results, open fractures required longer time to union, and showed higher rate of high-energy trauma.
