1 | 45 | 33 | 18 | 4.5 (1–11) | A loss of Böhler’s angle measured at follow ups was associated with a poor clinical outcome [27]. |
2 | 44 | 52 | 0 | 4-14 | The ratio of Böhler’s angle of the fractured side to that of the normal side was significantly lower in patients with unsatisfactory outcomes at final follow up evaluation [28]. |
3 | 43 | 47 | 0 | 1 | Böhler’s angle measured at the final follow-up did not correlate with the clinical result [20]. |
4 | 63 | 30 | 33 | 5.1 | No correlation between Böhler’s angle and final functional outcomes [23]. |
5 | 88 | 44 | 44 | 2 | There was a significant negative correlation between change in Böhler’s angle (angel measured at 3-month minus angle at the time of injury) and SF-36 score in surgical group [13]. |
6 | 70 | 29 | 41 | 6.5 (4–15) | Patients with displaced fractures had a good outcome following operative treatment with restored Böhler’s angle>10 degrees [22]. |
7 | 26 | 15 | 11 | 15 (11–18) | No correlation between Böhler’s angle and functional outcome [14]. |
8 | 16 | 16 | 0 | 2 (1–4) | No correlation between good restoration of Böhler’s angle and high functional score [29]. |
9 | 47 | 47 | 0 | 10 (7–15) | Restoration of Böhler’s angle ≥30 degrees was associated with a better outcome [21]. |
10 | 274 | 274 | 0 | 6 (4–8) | The preoperative Böhler’s angle has a significant correlation with Sanders classification. The postoperative Böhler’s angle has a significant correlation with the final functional outcome (The current study). |
