To evaluate unilateral external fixation when applied as the standard treatment of children with displaced femoral shaft fractures.
Two county hospitals in central Sweden.
A consecutive and prospective study including all children aged 3 to 15 years with displaced femoral fractures admitted to either of the two hospitals. Patients were followed clinically and radiographically until healing and at 1 year.
A total of 96 children with 98 fractures were treated with the same kind of external fixator during the period 1993-2000. The mean age was 8.1 years (range 3-15 years). Average hospital stay was 8.7 days (median 7 days). Average time of external fixation was 61 days (range 37-127 days; median 56 days). Minor complications included pin track inflammation/infection in 36 of 98 (37%) fractures. In 18 of 36 fractures, a short treatment with oral antibiotics was given. Other minor complications were one heterotopic ossification, one patient with two rereductions, nine cases of clinically insignificant malunion (varus = valgus > 5 degrees or procurvatum > 10 degrees ), and one leg-length discrepancy greater than 2 cm. Major complications (6%) included two refractures, one through a pinhole and one at the fracture site, both after significant trauma. Three of the older children with transverse fractures after high-energy injury developed a bending due to premature removal of the fixator prior to healing and required corrective osteotomies. One boy had a third rereduction because of displacement after a fall.
The use of external fixation as a standard treatment of uncomplicated displaced femoral shaft fractures in children gave satisfactory results. The surgical learning curve was short, and the advantages compared with nonsurgical treatment included shorter hospital stay, early mobilization, and fewer days out of school for the patient and out of work for the caregiver. We believe that the advantages far outweigh the complications, many of which can be avoided.
