“…Unsatisfactory clinical results reported in 10% to 20% of patients treated with in situ pin fixation has lead some to advocate that, for severe deformities, surgeons should attempt to downgrade the degree of deformity or to correct the deformity to mitigate the long-term risk of cartilage damage. [69][70][71][72] For mild SCFE or healed proximal femoral deformity producing impingement, surgical dislocation, limited anterior open or arthroscopic approaches with femoral neck osteochondroplasty have been reported. [73][74][75] Osteotomy can be performed at the intertrochanteric, basicervical, or subcapital levels depending on the extent of physeal healing and degree of deformity.…”
