EARLY AGGRESSIVE MANAGEMENT OF SLIPPED UPPER FEMORAL EPIPHYSIS FOLLOWING THE BERNESE PHILOSOPHY



Abstract

Since 2003 we have adopted an aggressive approach to the management of slipped upper femoral epiphysis (SUFE) deformity, an important cause of femoro-acetabular impingement and associated with the development of early adult hip arthritis.

Sixteen patients aged 16.7 years (range 11–20), 13 male, have undergone surgery to manage their SUFE deformity. Nine underwent primary surgery using a Ganz approach (7) or in-situ pinning with femoral neck resection via a Smith-Peterson approach (2). Seven had previously undergone in-situ pinning 26 months earlier (range 4–44 months) of whom two had acetabular chondral flap tears with eburnated bone and six had significant labral degenerative changes associated with calcification or tears. Only one of the nine patients who underwent primary aggressive management of their SUFE, had a labral tear. Four patients underwent mobilisation of the femoral head on its vascular pedicle, followed by anatomical realignment.

At an average follow-up of 22.3 months (range 1–41 months) 15 remained well with excellent function. Leg lengths remained equal in 12, with average shortening of 2 cm in the remaining four. Segmental AVN occurred in the first patient after damage to the vascular pedicle during drilling of the neck; the technique has been modified to prevent this.

Despite having performed over 400 surgical hip dislocations, the authors continue to find the management of this condition challenging; nevertheless, having seen the consequences of femoro-acetabular impingement in these young patients, we believe that aggressive management to correct anatomical alignment is essential for the future well being of the hip.
