Background:
Minimally invasive posterior displacement calcaneal osteotomy (PDCO) is often used in hindfoot deformity correction in the adult population, but there is a paucity on its use in children. The aim of this study was to compare the clinical and radiographic outcomes of open versus minimally invasive PDCO (MI-PDCO) approach in children.
Methods:
This is a consecutive series of PCDOs performed as a component of a complex foot and ankle reconstruction.
Results:
Twenty-nine calcaneal osteotomies in 23 patients aged 13.0 ± 3.0 years were included. Eleven osteotomies were performed open (O-PDCO) and 18 MI-PDCO. Mean follow-up was 35.4 ± 19.1 months. No delayed union, non-union, or apophyseal growth disturbance was observed. Seven nerve paresthesias were observed, two in the O-PDCO (18.1 %) and five in the MI-PDCO (27.7 %) group, all improved.
Conclusion:
These results support MI-PDCO as a safe and effective alternative technique to conventional O-PDCO to correct pediatric hindfoot deformities.
Level Of Clinical Evidence:
Level 3 (retrospective comparative study).
