  • See a complete list of the surgical procedures by category in Table 1. Percentages may not add to 100% because patients could have had >1 type of procedure at a given age.

  • a n equals the number of patients in the respective age category. Patients might appear multiple times across age categories because they might have had multiple visits to the registry at different ages during the study period.

  • b This number is expected to be 100% for this category of patients but, until recently, reporting the initial spinal closure was not mandatory for member clinics (see text for explanation).
