Key result
Prophylactic pinning of the contralateral hip in slipped capital femoral epiphysis prevents severe arthrosis, which occurs in 25% of untreated hips before age 50.
Why the study?
Does prophylactic pinning prevent arthrosis in the contralateral hip in patients with slipped capital femoral epiphysis?
Does prophylactic pinning prevent arthrosis in the contralateral hip in patients with slipped capital femoral epiphysis?
Absolute Event Rate: 0% vs 25%
Prophylactic pinning of the contralateral hip in SCFE is recommended to reduce the risk of severe arthrosis and the need for repeated radiographical examinations.
May support prophylactic pinning to avert severe arthrosis; leaves open confirmation in prospective trials.
The risk of contralateral slipping in slipped capital femoral epiphysis (SCFE) has been estimated to be 40-80% in follow-up examinations. Before age 50 years, 25% of the contralateral hips with untreated slipping showed arthrosis, some severe. In the same long-term follow-up, no hip with mild or moderate slipping treated with pinning in situ had developed severe arthrosis at that age, indicating the risk of arthrosis in the contralateral hip in SCFE can be reduced by prophylactic pinning. Prophylactic pinning also diminishes the need for repeated radiographical examination during the remaining growth period. Provided that a technique with a low complication rate is used, prophylactic pinning of the contralateral hip is recommended in all cases of SCFE.

Gunnar Hägglund (1996) conducted a review in Slipped capital femoral epiphysis (SCFE). Prophylactic pinning vs. Untreated slipping was evaluated on Severe arthrosis. Prophylactic pinning of the contralateral hip in slipped capital femoral epiphysis prevents severe arthrosis, which occurs in 25% of untreated hips before age 50.
