Simultaneous slipped upper femoral epiphysis in identical twins

Simultaneous slipped upper femoral epiphysis in identical twins.

The exact cause of slipped capita! femora! epiphysis remains unclear. Hormonal imbalance has been suggested but has not been substantiated by a recent study (Brenkel et a! 1989). A strong familial incidence has been well documented by Rennie (1982), who suggested an autosoma! dominant pattern of inheritance with variable penetrance. To date only two cases have been described in identical twins ...

Familial slipped upper femoral epiphysis.

Bilaterality in slipped upper femoral epiphysis.

The frequency of slipping and osteoarthritis of the contralateral hip was recorded in 260 patients with slipped upper femoral epiphysis between 1910 and 1960. Twenty-three of these patients (9%) had primary bilateral slipping, 32 (12%) had a contralateral slip diagnosed later during adolescence and a further 104 (40%) had signs of contralateral slipping at follow-up 16 to 66 years later, giving...

Chondrolysis in Slipped Upper Femoral Epiphysis

of 44 patients (55 hips) with slipped upper femoral epiphysis treated from 1963 to 1989, 13 (14 hips) developed chondrolysis. Eight hips had chondrolysis at the time of presentation, all in female patients who were either coloured or black and who had moderate or severe slips. The other six hips had persistent pin penetration of the joint; in five of these the pin penetrated the anterosuperior ...

Slipped upper femoral epiphysis after radiotherapy.

Eight slipped upper femoral epiphyses in patients who had had radiotherapy are described. These cases involved five patients in an "at risk" population of 48. This increased incidence is highly significant.
