Fixation in slipped capital femoral epiphysis avoiding femoral-acetabular impingement

  Fig. 1. SCFE of the left hip in an 11.2-year-old boy. a, b AP view radiograms: a post-operative α angle and b α angle at 12 months FU. c, d Lateral view radiograms: c post-operative α angle and d α angle at 12 months FU: observe the normalization of the angle and the absence of head/neck deformity (case 23 in Tables 1 and 2)

  Fig. 2. SCFE of the right hip in a 13.7-year-old boy. a, b AP view radiograms: a post-operative and b at 12 months FU: neck length (O-L) was measured from the lateral femoral cortex drawing a line perpendicular to the physis plane; the neck grew in the same way on the affected and unaffected sides, as growth of the femoral neck progressed, the screw advanced into the femoral neck from the lateral femoral cortex closing the gap between the lateral femoral cortex and the screw head. c, d Lateral view radiograms: c post-operative α angle and d α angle at 12 months FU: observe the normalization of the angle and the absence of head/neck deformity. Remodeling, due to the growth, eliminated the bump of the neck evident in the postoperative radiogram (c) (case 16 in Tables 1 and 2)
