Painful sequelae of coxa plana
NM Clarke and MH Harrison
Thirty-one patients with an average age of twenty-seven years had painful
hips as the result of coxa plana in childhood. The pain was severe enough
for surgical relief to be considered. Radiographically the lesions could be
subdivided into three groups: severe mushroom deformity of the femoral
head, 43 per cent; less severe dysplasia of the hip, 27 per cent; and
severe osteoarthritis, 30 per cent. Twenty-three hip operations were done
on theses patients. Fifteen hips showed radiographic evidence of definitive
premature closure of the femoral capital epiphysis. The series is presented
to illustrate that coxa plana may be followed by major disability in the
hip within the first three decades of life.
