ABSTRACT
Objective@#To evaluate the composite external fixation in the treatment of children with fracture of lower extremity metaphysis.@*Methods@#A retrospective analysis was conducted of the 42 children with fracture of lower extremity metaphysis who had been admitted to Zhengda Shaoyang Orthopaedic Hospital between September 2016 and September 2018. They were 24 boys and 18 girls, aged from 3 to 14 years (mean, 8.3 years). Open injury occurred in 10 cases, with type Ⅰ in 2, type Ⅱ in 7 and type Ⅲ in one according to the Gustilo-Anderson classification, and closed injury in the other 32 ones. The fracture happened at distal femur in 12, at proximal tibia in 9 and at distal tibia in 21 cases. All the patients were fixated with composite external brackets. Fracture healing, functional recovery of the knee and ankle joints, and complications were recorded.@*Results@#All the 42 patients were followed up for 12 to 18 months (mean, 15.8 months). All fractures healed well by the first intention with no malunion or no alignment change on the full length X-ray films of both lower limbs. Irritant growth within 1.5 cm was observed in 2 cases. No loosening occurred in the external fixation which was removed 3 to 5 months after surgery (mean, 3.8 months). Functional recovery of the knee and ankle joints was good at the last follow-up. For the patients with distal femoral metaphysis fracture, the knee function by the Merchan scoring was excellent in 3 cases, good in 7 cases, fair in one and poor in one; for the patients with proximal tibial metaphysis fracture, the knee function by the Merchan scoring was excellent in 3, good in 4 and fair in 2 cases; for the patients with distal tibial metaphysis fracture, the ankle function by the Kofoed scoring was excellent in 11, good in 7 and fair in 3 cases, giving an excellent and good rate of 83.3%. Of a total of 228 needle channels in the 42 patients, 58 were infected mildly or moderately, giving an infection rate of 25.4%. All the infections responded to active dressing change.@*Conclusion@#The composite external fixation brackets are a good choice for the treatment of children with fracture of lower extremity metaphysis, because they are easy in manipulation and stable in configuration, and can reduce the iatrogenic injury to the epiphyseal plate, spare cross-articular fixation and allow early functional exercise.
