Acute femoral head spasm in children is the most common hip disease in children aged 9 to 16 years. About 11 out of every 100,000 children in the United States suffer from this disease, which requires timely treatment through surgery. And now scientists from the University of California, San Diego have used the 3D printed patient hip model to reduce surgery time by about 25%.
In the study, Dr. Vidyadhar Upasani, a pediatric orthopaedic surgeon, performed surgery on 10 children. He prepared a 3D printed model of their hip for five of them. These models were produced by a team led by medical student Jason Caffrey using a CT scan of the patient's pelvis. The model simulates the honeycomb internal structure of the skeletal structure.
For the other five patients, Upasani did not use the model. Instead, he relied on the traditional method of studying hip X-rays before surgery. Two other surgeons performed surgery on different groups of 5 patients without first performing surgery on the model.
When comparing everything, the model-guided operative time was 38-45 minutes shorter than the two controls. According to the data provided by the university, this means that at least a time benefit of $2,700 is saved per surgery. The one-time cost of the printer used is approximately $2,200, and the material cost per model is approximately $10.
The study was conducted at the Reddy Children's Hospital in San Diego, where the orthopaedic department has purchased its own 3D printer.
