Abdominal oblique muscle injury is characterized by acute pain and localized tenderness over the lateral trunk. This injury is particularly common among throwing athletes, and usually presents as anterolateral abdominal wall pain. Imaging evidence is scarce in regard to whether oblique muscle injury at its junction with the thoracolumbar fascia can instead present with low back pain. A high school baseball player with unilateral low back pain was referred to us with a different diagnosis. Careful palpation and magnetic resonance imaging guided our care, and the patient returned to high-level competition after 7 weeks of conservative treatment, with no report of recurrence in the subsequent 12 months. Oblique muscle injury at its junction with the thoracolumbar fascia should be added to the differential diagnosis for throwing athletes with unilateral low back pain following a torque movement.
腹外斜肌损伤的特征是外侧躯干急性疼痛和局部压痛。这种损伤在投掷运动员中尤为常见，通常表现为前外侧腹壁疼痛。关于与胸腰筋膜交界处的斜肌损伤是否会出现腰痛，影像学证据很少。一名高中生棒球运动员因单侧腰痛被转诊给我们，诊断结果不同。仔细触诊和磁共振成像指导了我们的治疗，患者在 7 周的保守治疗后恢复到高水平比赛，随后 12 个月内无复发报告。对于进行扭转运动后单侧腰痛的投掷运动员，应将斜肌与胸腰筋膜交界处的损伤纳入鉴别诊断。
