Outcome of the unaffected contralateral hip in unilateral slipped capital femoral epiphysis: a report comparing prophylactic fixation with observation.
This was a retrospective review of 80 patients with unilateral slipped capital femoral epiphysis treated with either prophylactic fixation or observation. The unaffected hip of 44 patients (mean age 12.6 years) were subjected to simultaneous prophylactic fixation and 36 patients (mean age 13.4 years) were managed by observation. Fisher's exact test showed a significantly high incidence of sequential slip of unaffected hips in the observation group in comparison with prophylactic fixation (P=0.002). No cases had avascular necrosis or chondrolysis. Prophylactic fixation significantly reduces the incidence of sequential slip. It outweighs the minimal surgical risks compared with its benefit in the prevention of further sequential slip.
