Surgical treatment of femoroacetabular impingement after slipped capital femoral epiphysis: a systematic review

The aim of this recently published study was to assess the existing literature from 2005 to 2016 on the effectiveness of surgical treatment in patients with femoroacetabular impingement syndrome secondary to slipped capital femoral epiphysis.
A search was made of the electronic databases Medline, Embase and Pubmed. Data recorded included patient demographics, surgical technique, results of the operations and complications. Fifteen level V studies were included, comprising 261 patients (266 hips). The treatment groups included arthroscopic osteochondroplasty, surgical dislocation of the hip and traditional open osteotomy. The corrections of the alpha angle were 32.14°, 41.45° and 6° for arthroscopy, surgical dislocation and open osteotomy respectively. Each group showed satisfactory clinical results according to the clinical rating scales. Major complications were recorded in 1.6%, 10.7% and 6.7% for arthroscopy, surgical dislocation and osteotomy respectively.
The authors concluded that, in femoroacetabular impingement associated with slipped capital femoral epiphysis, surgical dislocation showed improved correction of the alpha angle but with a higher complication rate and higher reoperation rates than arthroscopic treatment and open osteotomy. There appears to be a need for more high-quality studies with standardised radiological and clinical outcomes in young patients in order to clarify the effectiveness and the safety of these treatments.
