Introducing the new
Patient-specific 3D-printed shelf implants for the treatment of Canine Hip Dysplasia
3D HIP is a patient-specific 3D-printed titanium implant specially developed to become a very effective, but the least invasive and least traumatic treatment for Canine Hip Dysplasia in the market today.
The 3D HIP
Compared to the very invasive Double and Triple Pelvic Osteotomies (DPO and TPO), both with extensive learning curves, the 3D HIP technique offers orthopedic surgeons the following advantages:
This shelf implant is custom fitted for each patient based on CT scans, with holes for locking screws integrated in pre-planned positions. Pre-surgery analysis and testing via motion simulations further ensures precise fit and positioning of the shelf implant, resulting to higher success rates, low complications, rapid recovery, and high joint stability.
Made of Titanium which has the advantage of superior biocompatibility, it promotes faster bone healing and limits uncontrolled bone proliferation.
The seamless fit to the hip socket and the good femoral coverage in all load-bearing quadrants of this personalized 3D-printed shelf implant result to rapid recovery and high joint stability. Patients may not require post-operative lifestyle restrictions following a standard period of limited exercise restriction.
Pre-planned in 3D, this straightforward technologically-driven approach cuts down the surgery time significantly.
Compared to the DPO/TPO (Double or triple pelvic osteotomy) techniques, which involve making two or three cuts in the pelvis to allow the socket to be rotated to provide adequate stabilisation for the head of the femur, and then fixing a plate to maintain the new positioning of the bones, the 3D HIP Technique is a much less invasive and traumatic procedure.
Pre-planned in 3D, and therefore not entirely dependent on the intraoperative experience of orthopedic surgeons, the 3D HIP Technique requires only a short learning curve due to its simplicity and its technologically-driven approach.

3D HIP IS BORN
A brief summary of how 3D HIP came to be
The gold standard surgical treatment options for hip dysplasia are the Triple Pelvic Osteotomy (TPO) and Double Pelvic Osteotomy (DPO). TPO and DPO are invasive surgeries with an extensive learning curve.
Another procedure, which is one of the oldest and most straightforward treatments for hip dysplasia, is shelf arthroplasty using bone grafts. While this procedure shows promising results, there are still some limitations to the technique, such as deficient coverage on the anterior and posterior quadrants of even the well-placed shelfs. Other than that, the success of this method relies heavily on precise bone graft positioning and fit.
Later, shelf arthroplasty was performed using Biocompatible Osteoconductive Polymer (BOP). As the procedure is not pre-planned in 3D, its success is entirely dependent on the intraoperative experience of the surgeon. Although initial clinical results were promising, one study in normal dogs showed that ossification around the BOP fibers was slow and unsatisfactory to recommend its use for the treatment of hip dysplasia.
The current advances in 3D-printing technologies made 3D HIP possible. 3D HIP is a personalized 3D-printed shelf implant that enables a seamless fit and good coverage on all load-bearing quadrants. Paired with the advantages of titanium such as superior biocompatibility, this first of its kind pre-planned and dog-specific 3D-printed titanium implant offers a safer and more feasible solution.
