Hi, I am so sorry to hear about your mothers injuries. I hope the injury and scans which show the injury to the vertebrae have been evaluated and I hope she is on at least some form of oral narcotic for pain. Now as far as more definitive treatment for such injuries while undergoing chemotherapy for cancer. That is a tricky situation that requires constant communication between your hemato-oncologist and your Neuro or Prtho Spine guy. They may opt to defer any long term treatment and instead try pain management solutions like giving her a back brace to stabilize the spine and trying local steroid and pain medication injections in the region of the fracture. Surgical interventions while undergoing chemo are always complicated by the fact that the chemo may delay the healing from the surgery and make issues worse than they already were. All in all, I would conference with your healthcare team and make sure the Spine and Onc guys are on board and communicating well. Then I would discuss external braces and pain management strategies. This in my opinion should be your plan of attack. I really hope this helps. It s a rough spot to be in and kudos to you for caring for you mother as you do. I wish her and you the best. If you wish to discuss her case in further detail. You can try our Ask a Specialist subscription service and have a back and forth with a number of doctors on our network. The idea being that you bounce ideas off of different specialists. Thanks for coming to HealthCareMagic.com
