Abstract

HILTON, TL; CAMPBELL, N  and  HOSKING, K. Additive manufacturing in orthopaedics: Clinical implications. SA orthop. j. [online]. 2017, vol.16, n.2, pp.63-67. ISSN 2309-8309.  http://dx.doi.org/10.17159/2309-8309/2017/v16n2a9.

BACKGROUND: The reconstruction of complex pelvic trauma or developmental bone abnormalities is challenging as it involves in-depth understanding of a complex three-dimensional structure. Advances in medical imaging and rapid prototyping allow for detailed pre-operative planning and manufacture of planning models, custom jigs and prostheses to make this type of surgery manageable with good results. METHODS: We report the reconstruction of a hip and proximal femur using planning models, jigs and custom prostheses produced by rapid prototyping methods. These tools helped to solve a complex problem and produced a good functional result for the patient RESULTS: In this case report the patient underwent the reconstruction of her right hip joint. She was unable to mobilise well independently prior to the surgery. The surgery provided her with a stable and functional hip joint. This allows her to mobilise independently with an external prosthesis. One year down the line she has a Fair MSTS score (14 of 30) CONCLUSION: Advances in medical imagining and rapid prototyping have produced planning and operative tools with which surgeons are able to solve complex problems safely and with good result. This technology has widespread use not only in orthopaedics but other surgical disciplines, and with increasing availability and improved cost effectiveness will be used more frequently in the future. Level of evidence: Level V (case report)

Keywords : pelvic reconstruction; proximal femoral focal deficiency; 3D printing; rapid prototyping.
