Ultrasound diathermy is widely used for the treatment of musculoskeletal disorders and other soft tissue injuries. Its use as a therapeutic modality is believed to be safe, with very few reported complications. Here, we report two patients who developed focal bone marrow abnormalities after receiving ultrasound diathermy. Both patients' magnetic resonance (MR) evaluations revealed linear subchondral bone lesions of the superolateral humeral head similar to those in osteonecrosis. The patients' symptoms subsequently improved, and available follow-up MR evaluation revealed near complete resolution of bone lesions. These findings suggest that ultrasound diathermy, and its interaction with bone tissue through thermal mechanisms, can cause focal bone marrow abnormalities. Furthermore, the bone marrow abnormalities seem to be transient, resolving upon cessation of ultrasound diathermy, therefore osteonecrosis should be differentiated from this temporal lesion.
超声透热疗法广泛应用于肌肉骨骼疾病和其他软组织损伤的治疗。人们认为将其用作一种治疗方式是安全的，报告的并发症极少。在此，我们报告两名患者在接受超声透热疗法后出现局灶性骨髓异常。两名患者的磁共振（MR）评估均显示肱骨头外上侧软骨下骨有线性病变，类似于骨坏死中的病变。患者的症状随后有所改善，现有的随访MR评估显示骨病变几乎完全消退。这些发现表明，超声透热疗法及其通过热机制与骨组织的相互作用可导致局灶性骨髓异常。此外，骨髓异常似乎是短暂的，在停止超声透热疗法后会消退，因此应将骨坏死与这种暂时性病变区分开来。
