We studied the natural course in patients with distal spinal agenesis(
DSA). Specifically, we compared children with different types of DSA (
Renshaw sacral agenesis types I-IV) and determined their maximum ambul
atory abilities, identified patients at risk for decubiti, determined
the average number of operations per patient, described associated con
genital anomalies, and sought a correlation between different types of
DSA and the risk of back pain and development of scoliosis. Through a
retrospective analysis, we concluded that there are definite correlat
ions between the specific type of DSA and the natural course with rega
rd to all these entities.
