The Outside‐In Technique for Slipped Capital Femoral Epiphysis: A Safe and Reproducible Approach in Hip Arthroscopy

Figures

• 

  Fig 1. Radiographic landmarks for preoperative planning. Observe the anteroposterior (AP) pelvis, 45 Dunn view, and frog view of a 12-year-old patient with slipped capital femoral epiphysis (SCFE).

• 

  Fig 2. Hip arthroscopy in the modified supine position, with maximal internal rotation of the foot for hip reduction. Observe the image intensifier placed in the anteroposterior (AP) and lateral plane.

• 

  Fig 3. Arthroscopic view of the right hip showing the slipped epiphysis, hematoma, and residual femoral deformity.

• 

  Fig 4. Final reconstruction of the slipped capital femoral epiphysis (SCFE) with cannulated screws. Observe the intraoperative images taken with the image intensifier in anteroposterior (AP) view, frog view, and 45 Dunn view.

• 

  Fig 5. A dynamic impingement test is performed. Observe the space between the femoral neck and the labrum in maximal hip flexion (upper left quadrant), the distracted hip with an intact labrum and a pristine femoral head (lower left quadrant), and the hematoma and inflamed ligamentum of teres (right).
