Erratum
After publication of this article [1], two errors were noticed in Table 1 and also in Table 3.
In Table 1 in the Radiographic evaluation section, one of the characteristics was displayed as: ≦ Larsen IV- no. (%), when it should have been: ≧ Larsen IV- no. (%).
Anzeige
In Table 3, one of the headings was displayed as MCA, when it should have been MAC, to refer to the Mean activity count.
The correct version of both Table 1 (Table 1 here) and Table 3 (Table 2 here) are displayed below. Both Tables have also since been updated in the original article [1].
