Satyajit Mondal, a 38-year-old man from West Bengal, was recently operated on by doctors from Manipal Hospital in Bengaluru to transplant a hip bone. The doctors took help from 3D printing technology to better pre-plan the complete surgery.
The Accident
Satyajit Mondal suffered a road accident two years ago when he was left with a painful hip joint. He had sustained a fracture dislocation of his right hip bone. Over the last two years, this pain was left untreated which resulted in a short, painful and immobile hip.
As the pain became unbearable he consulted Dr. Sunil G Kini, Senior Consultant Joint Replacement and Arthroscopy Surgeon at Manipal Hospitals, Bengaluru.
Dr. Kini quickly examined Satyajit’s right leg which as an inch and half short with painful and restricted hip movements. CT scans and radiographs of his hip joint showed that the ball of the thigh bone had cracked the socket bone which was the reason for the severe bone loss and malrotated pelvis.
Dr. Kini noted his observations and said, “The most important step was to plan well before the surgery. The patient was recommended the 3D printing technology to pre-plan his case. Since the anatomy of the whole pelvis and hip was now grossly distorted it would be a good idea to know exactly how his hip looks in comparison to a normal hip. The patient was recommended the latest technology of 3D printing to pre-plan his case better.”

3D Printed Model
To better understand the anatomy of the hip, the patient’s CT scan data was then used to accurately create a 3 dimensional model of his pelvis. The model was quickly created in a couple of days. The doctors used this model to carefully and accurately pre-plan the surgery.
Dr. Kini explained how the 3D printed model helped them in the surgery, “The 3D printed model is used to plan the surgery in terms of how we would like to position the implants and to identify the landmarks on the model that the surgeon would look for when he is in the operating theatre. In this case, the model also showed that hardly one-fourth of his original socket was intact and this would require a complex reconstruction procedure. We could execute all that we planned before and that also reduced our operating time.”
The surgery was successful and now the patient is recuperating very well. He is undergoing an extensive rehabilitation programme.
Speaking on how 3D printing can help numerous other surgeries, Dr. Kini said, “3D printing can be used to create patient-specific organ replicas. This would aid the surgeons to plan and practice on, before performing these complicated operations.”
