Secondary fractures associated with external fixation in pediatric femur fractures.

Sixty-six femur fractures sustained by children ages 4-14 years and treated with external fixation were reviewed retrospectively to assess factors influencing the incidence of refracture. The total rate of secondary fracture was 12% (eight patients) including five recurrent fractures at the original fracture site and three fractures through the pin sites. After removal of the external fixator, five patients refractured at the original fracture site and one patient fractured through a pin tract. Two patients fractured at pin sites while the fixator was still in place. Multivariate linear-regression analysis showed no correlation between the incidence of refracture and fracture pattern, percentage of bone fragment contact after fixator application, type of external fixator, or dynamization. A statistically significant association (p < 0.05) was found between the number of cortices demonstrating bridging callus [on both anteroposterior (AP) and lateral views] at the time of fixator removal and the rate of refracture. Fractures showing fewer than three cortices of bridging callus had a three (33%) in nine rate of refracture, whereas fractures with three or four cortices of bridging callus had a two (4%) of 57 rate of refracture.

Effect of delay of surgical treatment on rate of infection in open fractures in children.

This study reviews all open fractures treated at a tertiary children's hospital from 1990 to 1995 to determine whether delaying surgical debridement influences the rate of infection in the pediatric population. One hundred four open fractures were followed until both clinical and radiographic union was evident. A 1.0% rate of infection requiring surgical drainage, and a 1.0% rate of soft-tissue infection managed with oral antibiotics alone was found. Infection rates for fractures treated within 6 h of injury was 2.5%, and for fractures treated with >6 h delay was 1.6%. No significant statistical difference in infection rate with delay in surgical debridement was found (p = 0.77). Delays of 5 and 16 h were found in the two fractures complicated by infection, compared with an average delay of 12 h for those that healed uneventfully. Our findings suggest that in children given early parenteral antibiotics, operative irrigation and debridement may be delayed >6 h without an increased risk of infection. As this series contains only 18 patients with grade III open fractures and nine patients whose surgery was delayed >24 h, conclusions should not be made in these groups.

Variability in measurement of acetabular index in normal and dysplastic hips, before and after reduction.

This study examined the variability in the measurement of the acetabular index (AI) in normal and dysplastic hips, both before and after reduction. This variability for dysplastic hips is greater than that of normal hips. The variability is greater before an open or closed reduction than after reduction, and the variability after an open reduction is nearly 3 times greater than after a closed reduction. The 95% confidence interval of the AI is 10.1 degrees intraobserver and 21.9 degrees interobserver for all hips. The AI is most accurate in the situation in which it is most useful, after a closed reduction of a dysplastic hip. A 95% confidence interval of 5.1 degrees in this selected population supports the use of the AI for monitoring acetabular remodeling after closed reductions in accordance with previous clinical recommendations.
