E. Abraham et al., TREATMENT OF MODERATE TO SEVERE SLIPPED CAPITAL FEMORAL EPIPHYSIS WITH EXTRACAPSULAR BASE-OF-NECK OSTEOTOMY, Journal of pediatric orthopedics, 13(3), 1993, pp. 294-302
Extracapsular base of femoral neck osteotomy was performed in 36 hips
with moderate to severe slipped capital femoral epiphysis (SCFE). Foll
ow-up ranged from 2 to 24 years (average 9 years). According to modifi
ed Southwick's criteria, 90% of the hips had excellent or good result.
There were no cases of avascular necrosis (AVN). Prevention of perman
ent limb-length discrepancy >15 mm, as occurs in unilateral cases, war
rants close follow-up and contralateral epiphysiodesis when necessary.
We highly recommend this osteotomy as a safe and effective way to pre
vent further slippage and improve hip range of motion (ROM) in severe
chronic slips.
