Distal cordectomies as treatment for lumbosacral myelomeningoceles

Area of Science:

• Pediatric Neurosurgery
• Spinal Cord Malformations
• Developmental Neurology

Background:

• Lumbosacral myelomeningocele is a complex congenital condition affecting spinal cord development.
• Assessing the impact of surgical interventions on neurological function is crucial for patient outcomes.

Purpose of the Study:

• To evaluate the effect of distal cordectomies on lower extremity motor function in infants with lumbosacral myelomeningoceles.
• To determine the safety and efficacy of distal cordectomies in preserving motor function.

Main Methods:

• Retrospective review of medical records for 32 infants with lumbosacral myelomeningoceles.
• Analysis of preoperative and postoperative lower extremity motor function assessed by blinded therapists.
• Surgical technique involved dividing the cord between its exit from the spinal canal and the neural placode.

Main Results:

• Neurological function remained unchanged postoperatively in 29 out of 32 infants.
• Loss of motor function (hip flexion, foot plantar flexion, toe movement) occurred in 3 cases.
• The majority of infants demonstrated preservation of preoperative motor capabilities.

Conclusions:

• Distal cordectomies are associated with a high likelihood of retaining preoperative motor function in infants with lumbosacral myelomeningoceles.
• The surgical procedure appears to be safe for preserving lower extremity motor function in this patient population.
