The patient visited a traditional Chinese medicine clinic and was treated with unidentified plasters, which exacerbated the condition leading to involvement of the tibia 40 days before presentation (Figure 1(a)). The wound was debrided and washed repeatedly, and a 1.5 mm Kirschner wire was used to drill multiple pores in the exposed tibia until blood was seen (Figure 1(b)). On 23 January 2017, a healthy, uniform granulation tissue bed had developed over the exposed bone (Figure 1(c)). A 9 x 8 cm graft obtained from the right groin was fixed with suturing (Figure 1(d)). However, 2 years after discharge, outcomes remain satisfactory (Figure 1(e)).
