Objective      To determine the therapeutic effect of multi-section osteotomy and intramedullary fixation for correction of femoral deformity in the osteogenesis imperfecta children

and analyze the postoperative complications for prevention and treatment.       Methods      From Jan. 2007 to Dec. 2013

28 femoral deformity children with osteogenesis imperfect (totally 39 sides of femoral deformity)

were selected and treated with multi-section osteotomy and intramedullary fixation in our hospital. Their ages ranged from 3 years and 7 months to 14 years and 5 months

with an average age of 8 years and 4 months. During the operation

the average section of osteotomy was 1.9 (1 to 3). The children were randomly divided into elastic pin internal fixation group (20 sides for elastic intrameduary nails) and Rush nail internal fixation group (19 sides for Rush nails).       Results      All the patients were followed upfor an average time of 3 years and 8 months (from 1 year 3 months to 5 years 7 months). According to the Sanders grading standard to evaluate the hip function

11 cases were excellent

2 cases were good

7 cases were common and none was bad. For the children with Rush nails

16 cases were excellent

2 cases were good

1 case was common and none was bad.       Conclusion      Multi-section osteotomy and intramedullary fixation effectively corrects the femoral deformity in the osteogenesis imperfecta children

improves the appearance

changes the force relationship of the lower limbs

prevents fracture again

and promotes the life quality of the children. It is worth for wilder application with the effect of correction and low probability of fracture again and deformity of Rush nails.
