Abstract:
Objective To provide an accurate method for osteotomy in the treatment of developmental dysplasia of the hip with
steel osteotomy by three-dimensional reconstruction and Reverse Engineering technique. Methods Between January 2011 and
December 2012, 13 children with developmental dysplasia of the hip underwent steel osteotomy. 3D CT scan pelvic images
were obtained and transferred via a DICOM network into a computer workstation to construct 3D models of the hip using
Materialise Mimics 14.1 software in STL format. These models were imported into Imageware 12.0 software for steel osteotomy
simulation until a stable hip was attained in the anatomical position for dislocation or subluxation of the hip in older children.
The osteotomy navigational templates were designed according to the anatomical features after a stable hip was reconstructed.
These navigational templates were manufactured using a rapid prototyping technique. Results The reconstruction hips in
these children show good matching property and acetabulum cover. Conclusion The computer-aided design of osteotomy
template provides personalized and accurate solutions in the treatment of developmental dysplasia of the hip with steel
osteotomy in older children.
