Abstract
BACKGROUND: Severe flexible flatfoot deformity in children and adolescents is a complex problem. Calcaneal lengthening remains the gold standard for surgical correction at this institution. However, in a minority of patients, inadequate correction of valgus is noted at surgery and a further calcaneal shift osteotomy is done. METHODS: We have conducted a retrospective review of ten patients who received 15 combined minimally invasive calcaneal shift and calcaneal lengthening osteotomies, which were all performed by the senior author. All patients had failed conservative treatment. We describe our technique for double calcaneal osteotomy combining minimally invasive surgery (MIS) for the medial calcaneal shift with traditional open calcaneal lengthening osteotomy for treating children and adolescents with severe flexible flatfoot deformity. RESULTS: The average shift achieved was 8.07 mm. The average improvement in Meary's angle was 14.99°. All of them had radiological and clinical union at 12 weeks. None of the patients developed sural nerve injury, wound breakdown, or infection of the MIS incision. CONCLUSION: In double calcaneal osteotomies, the MIS calcaneal medial shift technique can be used safely with potentially lower risks of wound complications and sufficient medial shift, compared to conventional open extensive surgery. IMPLICATIONS: MIS calcaneal shift osteotomy has an advantage over open conventional open technique in cases where the skin is under tension like in combined calcaneal lengthening osteotomy. With experience, the procedure can be faster than an open procedure.
