139 Review of the role of bone-SPECT/CT in tarsal coalitions Figure 13. (a) The same patient as from Figure 12 was later treated with arthrodesis of the left subtalar joint because of TCC; however, the patient continued to experience pain complaints. Postoperative plain radiographs showed arthrodesis of the left non-osseous TCC, without pinpointing the possible pain generator. (b) Postoperative planar scintigraphy shows increased blood pool and bone turnover in the region of the left talocalcaneal articulation, which may indicate, but is non-specific for persisting TCC. TCC, talocalcaneal coalition. After arthrodesis of the subtalar joint because of a TCC, bone remodeling should slowly normalize in the fused joint and in the trajectory of the screw(s). The exact time of normalization of bone remodeling after arthrodesis in the foot is, as far as we are aware, unknown. In our experience, however, and also somewhat analogous to other osteosynthesis material such as hip- and knee prosthesis and spinal 5
