Abstract

Purpose: A minimally invasive anterior approach appears to be an attractive alternative to achieve capital realignment without violating femoral head vascular supply and avoiding hip dislocation in slipped capital femoral epiphysis. The aim of this study was to detail the technical steps of subcapital realignment through a minimally invasive anterior approach and to report the preliminary results of this procedure in a prospective cohort of patients with stable slips. Methods: Nine patients underwent subcapital cuneiform wedge resection through a minimally invasive anterior approach without hip dislocation for moderate or severe stable slips between April 2012 and April 2013. Prophylactic stabilization of the contralateral hip was performed in all cases. A minimum 18 months follow-up was available. Clinical course was assessed using the Harris hip score and the hip range of motion. The degree of slippage as proposed by Southwick, the lateral α angle and the epiphyseal-metaphyseal distance allowed radiographic assessment. Results: No patients were lost during follow-up, which was on average 28 months. No intraoperative complications occurred; one postoperative transient apraxia of the femoral cutaneous nerve, which completely recovered in six months, was recorded. Southwick angle, lateral α angle and epiphyseal-metaphyseal distance all improved substantially postoperatively. No cases of avascular necrosis were detected. Conclusion: Subcapital cuneiform wedge resection through a minimally invasive anterior approach without hip dislocation can be an easier alternative to restore proximal femoral anatomy in moderate to severe stable slips. Prospective case control studies are required to confirm these preliminary results.
