Purpose
To assess the value of 3D models of the hip joint in surgical care,
utilising current preoperative cross-sectional imaging modalities.
Our institution is a tertiary referral centre for patients with complex hip pathology and is one of the largest specialist young adult hip units in the country.
According to a recent publication by Arthritis UK,
“In 2012 over 80,000 THRs were performed in the UK.
More than 1 in 10 of the THR (approximately 8,600) were revision THRs,
and there is evidence that the number of revision THR procedures performed is increasing.
The exact time taken depends on the complexity of the individual case,
as all cases are different; however it takes at least twice as long to do a revision THR as it does to do a first-time THR.
This means that it takes a minimum of 2–3 hours and significantly longer in more complex cases.
It is specialist surgery requiring the use of specialist techniques and specialist equipment.”
Harnessing the power of new technology enables us to acquire and print 3D models from the pelvis and hip,
utilising existing,
up to date,
preoperative,
cross-sectional imaging.
To our knowledge,
this is the first study investigating the added value of 3D printing technology in CTHR.
We believe this approach enhances the surgical care pre-planning; with potential impact on both short-term and long-term patient outcomes as well NHS health economics.
