Favourable outcome of severe, unstable grade III slipped capital femoral epiphysis managed by closed reduction percutaneous pinning with mid-term follow up: A case report and literature review.

Slipped capital femoral epiphysis (SCFE) is one of the most common hip pathology in adolescents. Outcome of SCFE management largely depends on the grading of the pathology. Severe, unstable SCFE poses high risk for avascular necrosis (AVN). The objective of this study is to report a good outcome without AVN in an acute, unstable, high grade SCFE managed by closed reduction and percutaneous pinning along with factors that need to be given consideration. A 13 years old boy was unable to bear weight due to severe pain on right hip after trauma since 2 weeks. Patient was diagnosed with acute, unstable high grade SCFE, patient underwent closed reduction and percutaneous pinning (CRPP) using cannulated screw and K wire augmented with spica cast. At 12 weeks patient was already fully active. At 18 month follow up there was no sign of AVN with full hip range of movement. Treatment for unstable, severe SCFE is still challenging. Unreduced severe slippage will deliver serious impingement and end up with early degenerative arthritis. The magnitude of reduction in a severe, unstable SCFE poses high risk for AVN. While some studies claimed reduction is justified only when it is serendipitous, we successfully and purposely performed CRPP. Even after 2 weeks from onset, an acute and severe slippage can still be reduced closely and fixed percutaneously. The hip regain full range of motion with no sign of AVN on x ray at 18 months follow up. • Outcome of SCFE management depends on the grading of the pathology. • Severe, unstable SCFE poses high risk for avascular necrosis. • Successful treatment of severe SCFE can be achieved by closed reduction and percutaneous pinning (CRPP). • CRPP can be performed using cannulated screw and K wire augmented with spica cast.
