Split Cord Malformation

Split cord malformation (SCM), also known as diastematomyelia, is a rare congenital condition in which the spinal cord is longitudinally divided into two hemicords by a bony, cartilaginous, or fibrous septum within a single dural sac (Type II) or two separate dural sacs (Type I). This split can occur anywhere along the spine but is most commonly found in the thoracolumbar region. Embryologically, SCM arises from an abnormal accessory neurenteric canal during gastrulation, leading to aberrant tissue insertion and cord duplication. Patients may present in infancy or later childhood with back pain, scoliosis, neurological deficits, bladder dysfunction, or cutaneous stigmata such as hairy patches or dermal sinuses. Early recognition and management are crucial to prevent progressive neurological deterioration.

Split cord malformation (SCM) is a rare congenital condition in which the spinal cord is divided longitudinally into two hemicords by an abnormal bony or fibrous septum. This division usually occurs during early embryonic development, when the notochord and neural tube fail to form properly. In SCM, each hemicord may be encased within its own dural sac (Type I) or share a single dural sac (Type II). Because the spinal cord is partially split, nerve roots and blood vessels may be stretched or tethered, leading to a variety of neurological and orthopedic problems. The disorder most commonly affects the lower thoracic or lumbar regions, but can occur anywhere along the spine. Early diagnosis and treatment—often surgical—are crucial to prevent progressive neurological damage.

Types of Split Cord Malformation

Type I Split Cord Malformation
In Type I SCM, a rigid bony spur or osteocartilaginous septum divides the cord into two separate hemicords, each enclosed in its own dural sac. The rigid spur originates from an abnormal accessory neuroenteric canal that persists during embryogenesis. Because each hemicord has its own covering, the septum can tether the cord more firmly, increasing the risk of neurological deficits. Surgical correction typically involves removing the bony spur and resecting the abnormal meninges to untether the cord.

Type II Split Cord Malformation
Type II SCM features a fibrous or fibrovascular septum, rather than bone, dividing the cord within a single dural sac. The fibrous septum is more flexible but can still tether nerve roots and blood vessels. Neurological symptoms may be milder or progress more slowly than in Type I, yet patients can still experience pain, motor weakness, and sensory changes. Treatment focuses on excising the fibrous band and ensuring the cord is free to move within the spinal canal.

Causes of Split Cord Malformation

1. Abnormal Primitive Streak Formation
   During gastrulation, the primitive streak guides notochord development. Errors here can interrupt normal notochord formation, leading to a persistent accessory neuroenteric canal and subsequent cord splitting.

2. Persistent Endomesenchymal Tract
   A transient tract connecting endoderm and ectoderm usually disappears. If it remains, mesenchymal tissue can invade the neural plate, creating an abnormal septum.

3. Faulty Neurulation
   Neural tube closure typically completes by the fourth week of gestation. Disruption in this process can cause incomplete separation of the neural plate into a single tube, potentially splitting the cord.

4. Aberrant Notochord Injury
   Trauma or localized injury to the developing notochord may generate two adjacent cords as the body attempts to repair itself, leaving a septum.

5. Genetic Predisposition
   Mutations affecting genes that regulate neural tube closure (e.g., SHH, BMP pathways) can raise the risk of SCM, although specific gene defects remain under investigation.

6. Maternal Diabetes
   Poorly controlled maternal blood sugar during early pregnancy increases neural tube defect risk, including rare conditions like SCM.

7. Folate Deficiency
   Folate is crucial for DNA synthesis and neural tube closure. Insufficient maternal folate intake has been linked to a spectrum of neural tube anomalies.

8. Teratogen Exposure
   Certain drugs (e.g., valproic acid), alcohol, or environmental toxins can interfere with embryonic development, sometimes resulting in SCM.

9. Amniotic Band Disruption
   Early amniotic bands may entangle embryonic structures; if these bands involve the neural plate, cord splitting can ensue.

10. Vascular Insult
    Abnormal blood flow or hemorrhage near the developing spinal cord may physically separate hemicords.

11. Hyperthermia
    Excessive maternal fever in the first trimester has been associated with neural tube defects, potentially including SCM.

12. Radiation Exposure
    High-dose radiation during pregnancy can disrupt cell division in the neural tube, possibly causing splits.

13. Chromosomal Abnormalities
    Aneuploidies, such as trisomy 13 or 18, sometimes present with complex neural defects, including rare malformations like SCM.

14. Twin-Twin Transfusion Syndrome
    In monochorionic twins, imbalanced blood sharing can lead to developmental stress on one twin’s neural structures.

15. Embryonic Trauma
    Mechanical forces during embryogenesis, such as uterine constriction, may contribute to splitting of the cord.

16. Infection
    Maternal infections (e.g., rubella, cytomegalovirus) can interfere with normal spinal cord development.

17. Placental Insufficiency
    Poor placental blood flow leads to hypoxia during critical developmental windows, increasing neural defect risk.

18. Oxidative Stress
    Elevated free radicals in the embryo may damage neural tissue and lead to abnormal separation.

19. Maternal Obesity
    Obesity is an independent risk factor for neural tube defects, possibly through inflammatory mediators or metabolic disturbance.

20. Unexplained Sporadic Factors
    Many cases of SCM arise without identifiable risk factors, suggesting multifactorial causes and complex gene–environment interactions.

Non Pharmacological Treatments

Below are 30 non-drug therapies for SCM, broken into four categories. Each paragraph explains the therapy’s description, purpose, and mechanism in simple English.

1. Transcutaneous Electrical Nerve Stimulation (TENS)
TENS sends mild electrical pulses through the skin to reduce pain signals traveling to the brain. By stimulating large nerve fibers, it “closes the gate” to pain messages, improving comfort during daily activities.

2. Therapeutic Ultrasound
Ultrasound uses sound waves to create deep heat in muscles and connective tissues. This heat increases blood flow, relaxes tight muscles around the split cord area, and promotes tissue healing.

3. Heat Therapy (Thermotherapy)
Applying heat packs to the back helps unwind tense muscles, eases stiffness, and boosts circulation. Warmth can also reduce pain by soothing nerve endings.

4. Cold Therapy (Cryotherapy)
Ice packs applied briefly to sore spots slow nerve transmission and reduce inflammation, providing short-term relief after exercise or therapy sessions.

5. Low-Level Laser Therapy
Also called cold laser, this uses low-intensity light to stimulate cellular repair in nerves and soft tissues. It enhances healing and can lower pain and swelling.

6. Pulsed Electromagnetic Field Therapy
Pulsed magnetic fields encourage cell regeneration and improve blood flow. By gently stimulating injured tissues, this therapy can accelerate nerve recovery.

7. Spinal Traction
Gentle mechanical stretching of the spine reduces pressure on nerve roots. Traction creates space between vertebrae, which may ease pain and prevent further tethering.

8. Interferential Current Therapy
By delivering medium-frequency electrical currents, this modality penetrates deeper tissues without discomfort. It helps block pain signals and promotes muscle relaxation.

9. Hydrotherapy (Aquatic Therapy)
Exercising in warm water reduces gravity’s impact on the spine. Water resistance strengthens muscles gently, while buoyancy supports posture and decreases pain.
