The cases of 2 patients with valgus slipped capital femoral epiphysis
are presented. Additional imaging studies provide support for true pos
terolateral epiphyseal displacement. Increased femoral anteversion and
coxa valga contribute to the pathogenesis of valgus slipped capital f
emoral epiphysis. In situ pin fixation is recommended for stable valgu
s slipped capital femoral epiphysis. The importance of valgus slipped
capital femoral epiphysis lies in its recognition and appropriate scre
w placement when internal fixation is used. The percutaneous technique
should be used with caution. A limited open technique is recommended
when the anterior skin portal is near the femoral neurovascular bundle
.
