Epifisiólisis femoral proxima: revisión de 44 casos

We review 44 children with 47 slipped capital femoral epiphysis. There were 23 mild slips, 18 moderate, and 6 severe. Operative treatment was performed in all but one of the slips. In 10 cases prophylactic pinning of the contralateral hip was performed. Penetration of the joint by the implant was present in 17 (30%) of the 56 fixed hips. The average follow-up was 56 months (range: 3 to 178 months). The results, according to clinical and rocntgenographic parameters were excellent or good in 91% of mild slips, 77% of moderate and 33% of severe. As complications there were two cases of chondrolysis, both associated with joint penetration. In 2 (6%) patients where prophylactic pinning was not performed, contralateral hip slipping developed. In our study, results correlate with slip severity. We do not recommend prophylactic contralateral pinning.
