Our Summary

This research paper presents a new way of predicting the results of a type of surgery used to correct spinal deformities, such as scoliosis. The surgical technique, known as Anterior Vertebral Body Growth Modulation (AVBGM), involves connecting the bones in the spine in a way that helps to preserve flexibility in the lower back. Predicting the results of this surgery can be complex due to differences in patient’s bodies and the timing of their surgery.

To help with these predictions, the researchers created a computer model that learns from past surgeries and can predict the results of future ones. The model takes into account the unique shape and movement of each patient’s spine, as well as information about the spaces between the bones in the spine. It was trained on 3D models of 695 spines and tested on 72 patients who had the surgery. The model’s predictions were close to the actual results, with an average error of just 1.8mm. The model performed better than other deep learning and biomechanical models.

This could help surgeons plan and tailor the AVBGM procedure for each individual patient, potentially improving outcomes and reducing the need for additional surgeries.

Doctor’s Tip

One helpful tip a doctor might tell a patient about scoliosis surgery is to follow the post-operative care instructions closely, including any physical therapy or rehabilitation exercises recommended by the medical team. This can help ensure a successful recovery and optimal results from the surgery. It’s also important to attend all follow-up appointments with the surgeon to monitor progress and address any concerns promptly.

Suitable For

Patients who are typically recommended scoliosis surgery include those with severe curvature of the spine (greater than 40-50 degrees), progressive worsening of the curvature, pain that does not respond to conservative treatments, difficulty breathing due to the curvature of the spine compressing the lungs, and spinal deformities that are affecting the patient’s quality of life. Additionally, patients who have not achieved adequate correction with other treatments such as bracing may also be considered for surgery. Ultimately, the decision to undergo scoliosis surgery is made on a case-by-case basis by the patient and their medical team.

Timeline

Before scoliosis surgery:

  1. Patient is diagnosed with scoliosis through physical examination, X-rays, and other imaging tests.
  2. Patient undergoes non-surgical treatments such as bracing, physical therapy, and monitoring of the curve progression.
  3. If the curve progresses significantly or causes pain and other symptoms, the patient and their healthcare team may decide on surgery as the next step.

After scoliosis surgery:

  1. Patient undergoes pre-operative testing and preparation, including blood work, imaging tests, and consultations with the surgical team.
  2. Surgery is performed to correct the spinal deformity, which may involve the insertion of rods, screws, and bone grafts to straighten and stabilize the spine.
  3. Patient is monitored closely in the hospital for a few days post-surgery to manage pain, monitor for complications, and begin physical therapy.
  4. Patient is discharged from the hospital and continues physical therapy and follow-up appointments to monitor the healing process and ensure proper spinal alignment.
  5. Over time, the patient gradually returns to normal activities and experiences improved posture, mobility, and quality of life.

What to Ask Your Doctor

Some questions a patient should ask their doctor about scoliosis surgery with AVBGM include:

  1. What specific factors will you consider when determining if I am a candidate for AVBGM surgery?
  2. How experienced are you with performing AVBGM surgery, and what is your success rate with this procedure?
  3. Can you explain the potential risks and complications associated with AVBGM surgery?
  4. How long is the recovery process after AVBGM surgery, and what can I expect in terms of pain management and physical therapy?
  5. Will I need additional surgeries or follow-up procedures after AVBGM surgery?
  6. What are the expected long-term outcomes and benefits of AVBGM surgery for my specific case?
  7. Are there alternative treatment options to consider before proceeding with AVBGM surgery?
  8. Can you provide me with information about the computer model you use to predict surgical outcomes and how it will be used in my case?
  9. What steps will be taken to customize the AVBGM procedure to my unique spine characteristics and movement patterns?
  10. Can you connect me with any past patients who have undergone AVBGM surgery to hear about their experiences and outcomes?
