Sonography is conventionally used to diagnose fractures by identifying cortical discontinuity in the bone. However, its usefulness for diagnosing lumbar transverse process fractures (LTPFs) remains unknown. In this series, we describe static and stress sonography findings during manual application of compression stress on the lateral lumbar vertebrae in 17 patients with LTPFs. Features of LTPFs on static sonography included cortical discontinuity (89.3%), hematoma (71.4%), step-off deformity (67.9%), and focal reverberation echo (78.6%). All LTPFs were confirmed on stress sonography. Thus, stress sonography should be considered for the detection of LTPFs when there is at least one static sonographic fracture sign.
超声检查通常通过识别骨皮质连续性中断来诊断骨折。然而，其用于诊断腰椎横突骨折（LTPF）的作用尚不清楚。在本系列中，我们描述了 17 例 LTPF 患者在对侧腰椎施加侧向压缩应力时的静态和应变成像结果。LTPF 的静态超声特征包括皮质连续性中断（89.3%）、血肿（71.4%）、台阶样畸形（67.9%）和局灶性混响回声（78.6%）。所有 LTPF 在应变成像上均得到证实。因此，当至少有一个静态超声骨折征象时，应考虑应变成像来检测 LTPF。
