Introduction
Myelocele is a rare and severe form of neural tube defect that affects the spinal cord during fetal development. It is considered one of the most serious types of spina bifida and requires immediate medical attention and long-term rehabilitation.
Definition
Myelocele is a congenital condition in which the spinal cord remains exposed on the surface due to the complete failure of neural tube closure. Unlike other forms, there is no protective sac covering the neural tissue, making it highly vulnerable to injury and infection.
Etiology
- Failure of neural tube closure in early embryonic life
- Genetic predisposition
- Folic acid deficiency during pregnancy
- Maternal exposure to infections or teratogenic drugs
- Environmental and nutritional factors affecting fetal development
Clinical Features
- Open spinal lesion without a covering membrane
- Exposed neural tissue on the back
- Severe neurological impairment below the lesion
- Commonly affects the lumbosacral region
- Associated congenital abnormalities may be present
Signs and Symptoms
- Complete or severe paralysis below the lesion
- Bladder and bowel incontinence
- Loss of sensation in affected areas
- Absent reflexes
- Delayed or absent motor development
Complications
- High risk of infection (e.g., meningitis) due to exposed tissue
- Hydrocephalus
- Severe orthopedic deformities
- Tethered cord syndrome
- Skin breakdown and pressure sores
- Increased morbidity if untreated
Risk Factors
- Inadequate folic acid intake during pregnancy
- Family history of neural tube defects
- Maternal diabetes or obesity
- Exposure to harmful drugs or chemicals
- Poor prenatal care
Physiotherapy Management
- Early Intervention: Essential to maximize functional potential
- Passive Range of Motion (ROM): Maintain joint flexibility
- Positioning Techniques: Prevent pressure sores and deformities
- Strengthening Exercises: Focus on unaffected muscle groups
- Postural Training: Improve trunk control and balance
- Mobility Training: Use of assistive devices such as wheelchairs
- Respiratory Care: Prevent complications due to immobility
- Skin Care Education: Reduce risk of ulcers and infections
- Family Education: Guidance for home-based care and handling
Conclusion
Myelocele is a vital congenital condition with important neurological and functional challenges. Early surgical care combined with continuous physiotherapy and multidisciplinary management can improve survival, decrease complications, and enhance quality of life.
What is myelocele?
Myelocele is a severe congenital neural tube defect where the spinal cord is exposed without a protective covering.
What are common symptoms of myelocele?
Symptoms include paralysis below the lesion, loss of sensation, bladder and bowel incontinence, and delayed motor development.
What is the role of physiotherapy in myelocele?
Physiotherapy helps maintain joint mobility, prevent deformities, improve posture, and enhance functional independence.
