“…The precise extent of bone deformity is difficult to assess from conventional imaging, especially in a complex structure such as the pelvis, and standard prostheses may often be inadequate to allow proper placement and stable fixation. 2,13,14 In response to these two problems, customised implants with the addition of plates, shaped specifically for the altered anatomy, and jigs to aid in the accurate placement of screws, have been developed. 2,12 In the case report described above the goals of the surgery were to provide a pain-free, stable hip joint with an improved range of motion to allow for prosthetic use.…”

“…Not only are these models able to supply quantitative and qualitative data on the acetabular defect but they also allow for a surgical rehearsal. 2 The rehearsal allows for simulating all the complicated surgical steps in advance and can help the surgeon to anticipate possible intra-operative complications. 4 This will help to reduce theatre time and allow for a smoother procedure.…”

“…1,2 The primary goals of achieving a long-term, functioning and pain-free hip joint after pelvic reconstruction are to recreate the integrity and symmetry of the bony pelvic ring and to balance the soft tissues carefully. 3 Pre-operative planning is essential in order to achieve these goals and must be based on a precise understanding of the deformity.…”

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.
