Tethered (Spinal) Cord Syndrome can be congenital or acquired. It occurs when  fibrous tissues connect to the spinal cord or Filum Terminale and creates a downward pulling on the cord (often stretching the cord itself). Tethering can happen anywhere in the spinal column, but more often occurs in the lumbar region. Tethered Cord Syndrome can cause an Acquired Chiari Malformation.

Symptoms: Neurogenic Bladder (urgency, overactive bladder, incontinence, problems starting urinary stream, problems emptying bladder, reoccurring Urinary Tract Infections); Constipation/Diarrhea; Bowel Incontinence; Sexual Dysfunction (decreased sensation to pelvic area, decreased sexual interest, difficulty reaching orgasm); Bowel Incontinence; Severe Lower Back Pain (worsened by activity); Leg Pain/Numbness and/or Muscle Wasting (atrophy); Scoliosis.

Identifying Markers Often Include: Sacral Dimple; High-arched Feet; Hammertoes; low Medulla Oblongata (MRI); Low Conus (to the L2/L3); Thick-short Filum Terminale, Diastematomyelia (part of the spinal cord is split), Intradural Lipomas (fatty accumulation inside the dura) and Lipomyelomeningocele. Sometimes, signs of Tethered Cord are NOT visible on MRI, they are then referred to as Occult Tethered Cord; in such cases, Tethered Cord Release is considered controversial amongst many surgeons.

Synonyms:
tethered cord, Occult Tethered Cord, occult tethered cord

Bridges are built as a means to assist people in getting over the things that obstruct their path. We are constantly facing obstacles when it comes to our health, so we decided to build a bridge! Chiari Bridges is a non-profit network built by Chiarians for Chiarians. Our goal is to provide information, substantiated by published studies, in a way that is easy to understand. We encourage readers, to not only read our articles, but look up every study for themselves and read that too. Print it out and sit down with a highlighter; read it as many times as necessary until you understand; then use it to talk to your doctors. Our doctors are under no obligation to read our articles, but they should be willing to read officially published studies from journals, especially those specific to their profession. As many of our authors are patients as well, all authors sharing original pieces will be writing under pseudo-ghost names, to protect them from being black-listed by their doctors. Chiari Bridges is not affiliated with any physician or medical group. You should in no way use this site as a replacement for diagnosis, treatment, or medical from a qualified medical professional. The information provided on our website is strictly for educational purposes, in order to help further the understanding of Chiari, and its associated conditions. Our goal is to share our collective experiences and the information we have gathered, with those in need of answers, that it may increase your knowledge and guide you in conversations with your doctors.
