Case report: injury of the spinal cord at birth

Spinal cord injuries at birth: A multicenter review of nine cases

OBJECTIVE

To report a multicenter study of nine cases of children presenting with a birth-related spinal injury.

METHODS

The medical charts of nine patients identified by a questionnaire sent to the members of the French Society of Pediatric Orthopedics (SOFOP) were reviewed.

RESULTS

The pregnancy was uneventful in all cases. The fetal presentation was cephalic in three cases, a breech presentation in four cases, and a face presentation in two cases. The lesion involved the cervical spine in six cases. Three patients presenting upper cervical injuries died before the age of six years. The six remaining patients experienced no neurological improvement.

CONCLUSIONS

These rare conditions occur during difficult deliveries with abnormal presentations, the most common being a breech presentation with entrapment of the fetal head. In a child with hypotonia, flaccid quadriplegia or high thoracic paraplegia after a difficult delivery, a spinal cord injury must be suspected and plain radiographs and MRI must be performed.

[Perinatal spinal cord injuries]

BACKGROUND

Injury to the spinal cord is still observed in the neonate. Its prognosis is poor.

CASE REPORTS

The first neonate was delivered by cesarean section for breech presentation with hyperextension of the neck. She rapidly developed acute respiratory distress and paraplegia. MRI showed spinal cord hemorrhage involving the cervical and upper thoracic cord with rupture of the cord. The patient died a few weeks later. The second neonate was delivered vaginally in breech presentation without any difficulty. She progressively developed tetraplegia evolving into spasticity. MRI showed stretching of cervical spinal cord. The patient later developed sphincter disturbances, repeated urinary and pulmonary infection and severe scoliosis.

CONCLUSIONS

Early prenatal damage to the spinal cord was possible in the first patient. Ultrasonography could help to evaluate the extent of damage. The condition leads to difficult ethical and therapeutic problems.

The association of hypopituitarism with small pituitary, invisible pituitary stalk, type 1 Arnold-Chiari malformation, and syringomyelia in seven patients born in breech position: a further proof of birth injury theory on the pathogenesis of "idiopathic hypopituitarism"

We report seven cases of hypopituitarism all having a history of breech delivery, asphyxia at birth, and syringomyelia. A small pituitary gland was found on MRI or CT in six cases, invisible pituitary stalk on MRI in five cases, and type 1 Arnold-Chiari malformation in six cases. A constellation of these abnormalities are best explained by traction of brain and spinal cord of the subjects exerted during breech delivery and further support the primary role of birth trauma in the genesis of "idiopathic hypopituitarism".

Spinal cord birth injury: value of computed tomographic myelography

The value of myelography in the assessment of spinal cord injury in the early neonatal period has not been documented, although this study has been recommended frequently in the literature. Eight neonates are reviewed who presented with the clinical features of spinal cord injury and who had myelography performed. Clinical features included difficult delivery, absent respiration, flaccid paralysis, sensory level, and neurogenic bladder. Myelography revealed that 7 patients had the early changes of swollen cord and 1 patient had the late changes of cord atrophy. None of the neonates had surgical intervention. One neonate died at 3 days of age, while 2 others died after prolonged ventilation. Of the 5 infants who survived, 3 still require ventilation and have spastic quadriparesis, 1 has almost recovered completely and 1 had spontaneous respiration and limb movement but brisk deep tendon reflexes when last examined at 1 month of age. Myelography, which was performed in the early neonatal period in our infants, was abnormal in all patients. Myelography is useful in confirming the diagnosis, outlining the level and extent of the lesion, and excluding extramedullary compression. Myelography may assist in the assessment of prognosis but did not alter management in our patients.
