Do Systemic Factors Influence the Fate of Nonunions to Become Atrophic? A Retrospective Analysis of 162 Cases

Figure 8

Frequency analysis of allergies in nonunion patients. (a) Hypertrophic nonunion patients suffered at least one allergy in 30.3% (n=30) whereas 15.9% (n=10) of the atrophic nonunion patients were allergy sufferers. An association was found between allergies and type of nonunion ((1)> = 4.311, p=0.041), patients with allergies were more prone to hypertrophic nonunions. (b) No difference significant difference in numbers of allergies could be evidenced comparing atrophic with hypertrophic patients ((3)> = 7.100, p=0.069) ( test, = p <0.05).
