First keep in mind that I am not able to provide a diagnosis, because I am unable to examine your father, this forum is for eduational purposes only. Myelomalacia means softening of the spinal cord and refers to damage of the spinal cord, in your fathers case from

Cpr - infant, but it does not repair damage that has been done. Since your father has worsening symptoms (he cannot walk) and his MRI indicated more compression, surgery is likely your best option to prevent further damage. However, the risks vs benefits of surgery have to be considered carefully when people are of advanced age, have other severe medical problems or if they do not wish to have surgery. Again, cervical decompression is unlikely to make is condition much better, but can stop the worsening of his symptoms. Medical options and relieve some of the swelling from the spinal cord with steroids, decrease the tightness of the muscles (spasticity) with medications susch as baclofen and treat pain. The medical options generally work best in conjunction with surgery. The decision to go to surgery is a personal one to discuss between you, your father and your surgeon. I wish you the best.
