Abstract
We describe a new method for corrective osteotomy and the fixation of lower limb deformities in children. Following osteotomy, the desired position is obtained and temporarily stabilized using an external fixator. Definitive fixation is performed with a plate and locking screws inserted percutaneously under fluoroscopic guidance. The procedure was performed in 18 segments in 11 patients. Corrections were performed in all planes. The mean follow up was 18 months (range 6-36 months). All patients were corrected to within 2 degrees of that which was planned. Union was obtained in 16 segments in ten patients within 6-16 weeks. The method was found to be effective for the correction of deformity in the pediatric population. Advantages compared to conventional methods include minimal soft tissue dissection and the ability to adjust the position before definitive fixation.
Highlights
Corrective osteotomies are commonly used in pediatric orthopedics for a wide range of indications
The purpose of this study is to present a technique for corrective osteotomy combining temporary external fixation during the procedure, with definitive fixation using a locking plate inserted through a small incision
The technique is applicable for correction in any plane in a long bone
Summary
Corrective osteotomies are commonly used in pediatric orthopedics for a wide range of indications. Corrections can be performed acutely or gradually. External, or a combination of both, with each method having advantages and disadvantages. External fixators enable further correction after the initial surgery, but carry an inherent incidence of pin tract infection. Internal fixators usually require extensive dissection for insertion [1,2,3,4,5]. The purpose of this study is to present a technique for corrective osteotomy combining temporary external fixation during the procedure, with definitive fixation using a locking plate inserted through a small incision. The technique is applicable for correction in any plane in a long bone. We describe a new method for corrective osteotomy and the fixation of lower limb deformities in children
