Thyroid hormone levels in patients with slipped capital femoral epiphysis.

Twelve patients with slipped capital femoral epiphysis and 12 age- and sex-matched controls were prospectively studied. Their height, weight, skeletal maturation, and thyroid status were assessed. The duration of symptoms and severity of the slip was recorded in the test group. There was no correlation between duration of symptoms and severity of the slip or delay in making the diagnosis and severity. Although 50 percent of patients with slipped capital femoral epiphysis were over the 90th percentile for weight, there was no overall significant difference in weight, height, or skeletal maturation between the two groups. There was no evidence of either overt or subclinical hypothyroidism in patients with slipped capital femoral epiphysis.
