Patients were categorized as vitamin D deficient (&lt;30 ng\/mL) vs normal (31-80 ng\/mL). The primary outcome was the incidence of reoperation secondary to nonunion. Secondary outcomes included incidence of reoperation not related to nonunion and the need for repeat reoperation.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>The average level in the vitamin D\u2013deficient group (n = 17; 36.2%) was 16.9 vs 46.4 ng\/mL in the normal group (n = 30; 63.8%).
