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

Figure 10

Concomitant injuries appeared more often in younger nonunion patients. (a) Although no significant difference was observed, data evaluation showed younger age of patients with accompanying injuries compared to monofracture patients for both atrophic and hypertrophic nonunion patients. (b) No statistically significant difference of body mass index could be evidenced comparing atrophic and hypertrophic nonunion patients with concomitant injuries. However, BMI of patients with atrophic nonunion and concomitant injuries was lower compared to patients with only one injury. In hypertrophic nonunion patients, the contrary could be evidenced (Mann-Whitney U-test, =p≤0.05).
