This case documents the progression of a sacral insufficiency stress fracture, initially involving the lateral left ala and later extending across the body of the sacrum to the right ala. The 'H' shaped distribution of increased uptake on radionuclide bone scanning is characteristic of this type of fracture, although variations of this pattern are also seen according to the severity of the sacral trauma. While the differing bone scan patterns of this particular fracture type are well established, it is unusual to document the progression of this fracture on bone scan in any one patient.
本病例记录了一例骶骨应力性不全骨折的进展情况，最初累及左侧翼，随后扩展至骶骨体并延伸至右侧翼。放射性核素骨扫描上摄取增加的“H”形分布是这类骨折的特征，不过根据骶骨创伤的严重程度，这种模式也会有所变化。虽然这种特殊骨折类型的不同骨扫描模式已得到充分证实，但在同一患者身上记录到这种骨折在骨扫描上的进展情况并不常见。
