Unreamed locked tight-fitting nailing for acute tibial fractures
Objectives:
Treatment of tibial fractures by unreamed locked nailing with loose-fitting nails has previously been shown to be associated with a low union rate and high implant failure rate. This report describes the authors' experience in using tight-fitting nails that were relatively larger than loose-fitting nails.
Design:
Prospective cohort study.
Setting:
University medical center.
Patients:
Forty-eight consecutive patients with fifty-two tibial fractures (excluding open IIIC fractures and those with bone loss) were studied: thirty-four men and fourteen women, with a mean age of 38 years. There were twenty-five closed fractures, nine Type I, eight Type II, four Type IIIA, and six Type IIIB open fractures.
Intervention:
Unreamed nailing with tight-fitting nails using the Russell-Taylor system.
Outcome Measures:
Union rate, time to union, complication rate, and functional recovery, as well as nailing time, hospital time, and crutch-walking time were recorded.
Results:
Union occurred in forty-eight of fifty-two fractures (92%) with a mean time to union of 18.2 weeks. Compartment syndrome occurred in three patients. Deep infection occurred in one Type II and one Type IIIB open fracture. Four fractures required additional exchange nailing or bone grafting to achieve union: one Type II, one Type IIIA, and two Type IIIB open fractures. Three malalignments resulted from operative technical error. The rate of both intraoperative bony split and screw breakage was 3.8% (2 of 52), but neither complication interfered with fracture healing. Recovery of joint motion was essentially normal in those patients without knee or ankle injury.
Conclusions:
Unreamed locked nailing with tight-fitting nails can produce satisfactory clinical results for acute tibial fractures. It has the advantages of technical simplicity and an acceptable risk of implant failure.
