The spelling of the word "rhachischisis posterior" can be a tongue-twister for some. The word is pronounced as /rækɪˈsɪsɪs pɒsˈtɪərɪə/, with emphasis on the second syllable "sisi". The term refers to a rare congenital defect in which the spinal cord remains unprotected due to the incomplete closure of the posterior neuropore. This condition can lead to neurological deficits and may require surgical treatment. While the spelling and pronunciation of "rhachischisis posterior" may be challenging, its recognition is important for proper diagnosis and management.
Rhachischisis posterior is a medical term used to describe a rare congenital condition characterized by the incomplete closure or absence of the posterior neural tube during embryonic development. The posterior neural tube is the structure that eventually becomes the spinal cord and spinal column. In rhachischisis posterior, the posterior part of the neural tube fails to close properly, resulting in a malformation and exposure of the underlying spinal cord.
Individuals with this condition may exhibit a variety of neurological abnormalities. The exposed spinal cord is vulnerable to injury and can lead to significant complications such as paralysis, muscle weakness, and sensory deficits. There may also be associated problems with bladder and bowel control.
Rhachischisis posterior can be diagnosed through a thorough physical examination, imaging techniques such as ultrasound or magnetic resonance imaging (MRI), and genetic testing to rule out any underlying genetic causes.
Treatment for rhachischisis posterior typically involves a multidisciplinary approach including pediatric neurosurgeons, orthopedic surgeons, and physical therapists. The primary goal of treatment is to prevent infection and further damage to the exposed spinal cord. Surgery may be performed to cover and protect the spinal cord, as well as to correct any associated spinal deformities.
The long-term prognosis for individuals with rhachischisis posterior depends on the severity of the condition and associated complications. Early diagnosis and intervention are crucial in minimizing potential neurological deficits and improving overall quality of life. Close monitoring by a medical team and appropriate rehabilitative therapies can help individuals with rhachischisis posterior achieve the best possible outcomes.

The word "rhachischisis" is derived from Greek roots. "Rhachi" means "spine" and "schisis" means "split" or "cleft". Therefore, "rhachischisis" refers to a split or cleft in the spine.
The term "posterior" in "rhachischisis posterior" indicates that the split occurs in the posterior or back region of the spine.
