[Calcaneus osteotomy in flexible flatfoot in children (long-term results)]

The static of serve flexible flatfeet in children can be positively influenced by the varisation osteotomy of the Calcaneous by Kramer. The method is technically easy and imposes very few complications. This follow-up after a meantime of 12.4 years looks at 30 osteotomies. Subjective results were excellent. Objectively, the results must be regarded as good. Nontheless, the problem remains who should be operated, especially if we keep in mind that the nontreated flatfeet usually develop positively. So this method should remain in the hands of the experienced orthopedic surgeon.
