ABSTRACT

Introduction: Slipped capital femoral epiphysis is the most common hip problem in the adolescent age group. It can involve both hips, presenting itself bilaterally at first presentation or sequentially. The overall incidence of bilateral disease is variable, but the risk of occurrence is higher when there is underlying endocrinopathy, renal disease and obesity.

Materials and Methods: Amongst the 36 cases (44 hips) of slipped capital femoral epiphysis that we had, there were 8 cases of bilateral disease, of which 3 were bilateral sequential slips. A retrospective review of all case records and X-rays was done.

Results: According to Aadalen’s criteria, the results were excellent or good in 37 hips, fair in 3 hips, and poor in 2 hips. Two patients were considered as treatment failure because of avascular necrosis. The incidence of bilateral slipped capital femoral epiphysis was 22.2%. The overall average age was 11.4 years. All cases of sequential involvement presented within 15 months of the initial slip. One patient had hypothyroidism (who also had a positive family history for slipped capital femoral epiphysis), while 91.6% were above the 75th percentile for weight. There was no statistically significant difference in age, sex, race, body mass index (BMI) and weight percentile distribution between patients with unilateral and bilateral disease.

Conclusion: Satisfactory outcomes can be expected in most patients treated for slipped capital femoral epiphysis. The risk of avascular necrosis is higher in unstable slips. The role of prophylactic contra-lateral pinning should be restricted to patients with hypothalamic-pituitary-ovarian axis disease, especially hypothyroidism.


Slipped capital femoral epiphysis is the commonest hip problem in the adolescent age group. The goals of treatment are aimed at avoiding the complications of osteonecrosis and chondrolysis, preventing further slips, and promoting physeal closure.
