Chapters:
0:00 Introduction
0:25 Dr. Rodriguez-Olaverri's personal scoliosis diagnosis. Age 12, 28 degree thoracolumbar curve.
2:39 Path to Spine Surgeon.
6:15 Initial exposure to non-fusion surgical option.
8:05 Waited for a non-fusion surgical system for scoliosis.
9:14 Quality of life is a top goal.
11:49 NYU is an opportunity to improve non-fusion research and surgical techniques.
14:09 Preference for ASC over VBT.
15:42 ASC offers the ability to both rotate and compress the spine to a greater degree.
16:15 Mini-open and a 2nd tether reduces tether breakage from 15-18% to less than 5%.
16:59 Similar surgical approach to Drs ABC.
18:20 Decision to do disc releases is based on x-rays and spine stiffness.
19:21 Prefers MRI to create 3D reconstruction of the spine.
20:24 Rib hump is a rotational, not a coronal deformity.
20:57 Anterior Vertebral Overgrowth drives scoliosis.
21:46 Has never seen over correction in curves over 55 degrees. Sees over correction in less than 30-40 degree curves with lots of growth remaining.
22:37 Need further research on curve flexibility and balancing curves for best correction.
23:34 Sees more bone overgrowth in the vertebrae of the most corrected curve.
24:56 ASC for mature curves may modulate both bone and muscle to stabilize curves after a broken tether.
25:58 Rotation is the first indication of tether breakage.
27:04 ASC allows greater spine de-rotation.
27:51 During scoliosis curve progression, rotation becomes before hypokyphosis.
28:26 Correcting rotation corrects hypokyphosis.
29:07 Fusion is all about de-rotating the spine.
31:25 Disc Release necessary to create kyphosis and rotation.
32:23 Disc release controversy.
33:03 Disc release details.
35:27 Practice is 90% paediatric and 10% adult.
37:31 Will there be availability in Spain for surgeries?
39:15 Youngest VBT patient is 5 years old.
41:47 Uses both Globus and Zimmer Biomet instrumentation.
43:19 Definite advancements in tether technology coming.
44:21 Needs to be different instrumentation systems for thoracoscopic and mini-open approaches.
45:45 Better screw purchase is important for top screw to allow better tensioning.
47:27 Any plans to tether higher than T4 for high thoracic curves?
48:41 VBT fusion hybrids.
49:46 Mature tethers.
58:44 BONUS INTERVIEW PART 2. Review of 2 Cases. Case 1: Immature Spine ASC. Case 2: Mature Spine ASC
58:54 Case 1 - 13 year old female, Risser 0, Sanders 2, Pre-menarche. Immature spine ASC.
1:04:31 Case 2 - 17 year old female, mature spine ASC.
