Дефект считают результатом неправильного развития эмбриональной хорды и нервной трубки с 15 по 18 дни беременности, когда происходит закладка основных зародышевых структур на этапе нейруляции. Аномальное сообщение между зачатком спинного мозга и примитивным нейрокишечным каналом или амниотическим мешком формируется путем создания эндомезенхимального тракта. Последний образуется из мезодермальных элементов, заполняющих патологический свищевой канал.
Разделение каудального мозга в продольном направлении сопровождается образованием костной, хрящевой либо фиброзной срединной перегородки или шпоры. Она исходит из тела или дужки позвонка, может распространяться на всю ширину спинального канала, прикрепляясь к вентральной части твердой мозговой оболочки. Спинной мозг на протяжении нескольких сегментов расщепляется на два обычно неравных рукава, снабженных собственным центральным каналом, что является основной патоморфологической особенностью диастематомиелии.
Общие эмбриогенетические механизмы обуславливают частую связь патологии с другими миелодиспластическими состояниями. Заболевание может сочетаться с миеломенингоцеле, спинальными липомами и кистами, дермальным синусом. Выявляют ассоциацию с врожденными дефектами позвоночника – гемивертеброй, бабочковидными позвонками, сколиозом. При множественных признаках дизрафии встречаются висцеральные пороки с поражением почек, прямой кишки и половых органов.
(Aching muscles, Lack of strength, Muscular fatigue, Decreased muscle power, Reduced muscle tone, Muscle exhaustion, Muscle debility, Lack of muscle control, Lack of muscular coordination, Loss of muscle strength)
Muscle weakness is a decrease in the strength of the muscles that can lead to difficulty in performing everyday tasks. It can manifest in a variety of ways, including fatigue, difficulty walking, and reduced range of motion. It can develop gradually or suddenly, and can be caused by a variety of med...
(Dissociated sensory deficit, Partial sensory loss, Differential sensory loss, Discontinuous sensory loss, Segmental sensory loss, Loss of sensation, Asymbolia, Partial anesthesia, Sensory disconnection)
Dissociated sensory loss is a neurological symptom characterized by the loss of sensation in a specific area of the body, while other areas remain unaffected. It is often caused by damage to the nerve pathways that transmit sensory information from the affected area. Symptoms typically include a lac...
(Bladder control problem, Urinary leakage, Involuntary urination, Urge incontinence, Overactive bladder, Stress incontinence, Functional incontinence, Mixed incontinence)

(Humpback, Roundback, Hunchback, Hunching, Swayback, Swaybacked, Concave back, Convex back, Hyperlordosis, Hypolordosis)
Kyphosis and lordosis are spinal conditions that involve an excessive curvature of the spine. Kyphosis is an outward curvature of the spine, resulting in a hump-like appearance in the upper back. Lordosis is an inward curvature of the spine, resulting in a swayback appearance in the lower back. Both...
(Spinal curvature, Curvature of the spine, Lateral curvature of the spine, Abnormal curvature of the spine, Side-to-side curvature of the spine, Lateral spinal deviation, Asymmetrical spinal curvature, Abnormal lateral curvature of the spine)
Scoliosis is a condition where the spine curves sideways in an "S" or "C" shape instead of its normal straight line. It can develop in childhood or adolescence and is characterized by uneven shoulders, a tilted pelvis, and a raised or lowered hip. It can also cause pain, fatigue, and respiratory pro...
