A new approach was developed for the treatment of planovalgus feet in
children who have spastic cerebral palsy and are less than six years old.
The procedure consists of subtalar stabilization (arthroereisis) with a
Vitallium staple, and it corrects alignment, restores balance, and allows
continued function. It is safe, technically simple, and efficient. Between
1980 and 1988, forty-eight arthroereises were done. The results of
thirty-one procedures in twenty patients who were two to ten years and ten
months old at the time of the operation were followed for an average of 4.1
years (range, two to seven years). Approximately 85 per cent of the results
were excellent or good. Only one foot needed a revision; this was due to
migration of the staple. At the most recent follow-up, the talocalcaneal
angle had not changed in about 50 per cent of the feet. In another seven,
the change ranged from 5 to 10 degrees. All of these patients had a
satisfactory result. In all but three feet, the goal of maintaining the
stability of the talocalcaneal joint without orthotics or osseous fusion
was achieved. Originally, the procedure was done only in patients who were
less than six years old, but, because of its success, the indications were
extended to children of any age who had severely involved and
neurologically compromised feet. Satisfactory results were obtained in the
older children as well.
