Intramedullary nailing of femoral fractures in children through the lateral aspect of the greater trochanter using a modified rigid humeral intramedullary nail: preliminary results of a new technique in 15 children.
OBJECTIVE
To evaluate the clinical results of intramedullary nailing of femoral shaft fractures using a rigid intramedullary nail placed through the lateral aspect of the greater trochanter in older children and adolescents.


METHODS
A retrospective study was carried out evaluating all skeletally immature patients with femoral shaft fractures treated using a modified rigid humeral intramedullary nail.


METHODS
Fifteen children and adolescents with displaced femoral diaphyseal fractures and open physes.


METHODS
Femoral shaft fractures in children and adolescents were stabilized using a modified humeral intramedullary nail placed through the lateral aspect of the greater trochanter.


METHODS
Patients were evaluated to determine time to union, final fracture alignment, hospital stay, complications, clinical outcome, and proximal femoral changes including avascular necrosis or proximal femoral valgus with femoral neck narrowing.


RESULTS
Fifteen patients were followed for a minimum of 1 year (range 70-157 weeks). The average age of the patients was 12 years and 5 months (range 8 years and 2 months-17 years and 1 month). All fractures healed at a mean of 7 weeks (range 5-14 weeks) after fracture. The average hospital stay for patients with isolated femur fractures (8/15) was 2.8 days (range 1-5 days). At an average follow-up of 141 weeks (range 70-326 weeks), no patient had developed avascular necrosis, femoral neck valgus, femoral neck narrowing, or other complications.


CONCLUSIONS
The technique of intramedullary nailing in children through the lateral aspect of the greater trochanter seems to be safe, effective, and well tolerated by patients.
