Abstract
Background: The physeal manipulation (guided growth) provides a method for angular deformity correction of the knee joint with fewer complications than an osteotomy.
The temporary partial growth arrest is of the least invasive physeal manipulation procedures
Material and Methods: Eighteen children patients (12 boys and 6 girls) with 36 knee angular deformities were treated by temporary epiphysiodesis method using the eight-plate (8-plate). Non-locked titanium 4.5-mm cannulated screws were used with the plate. The mean average age of the children at a time of the operation was 6.5 years (range, 4–11 years).
Results: All patients achieved complete deformity correction after plate removal and 2 cases had intended over correction of 8-10 degrees due to anticipated deformity recurrence because of the cause of deformity was Blount’s disease. These cases get corrected at three years the final follow-up after removal of the plates. Neutral mechanical axis with no MAD was the sign of complete correction.
Conclusion: The technique of eight-plate with its pivoting screw and plate design is a valid technique for angular knee deformities correction. According to the outcome of this study, we recommend using eight-Plate technique in correcting knee joint angular deformities with the proper patient selection.
