Internal oblique muscle injuries are common in professional baseball pitchers and may require a prolonged convalescence of up to 10 weeks. Most strains can be diagnosed clinically, but imaging can be helpful to assess the severity of injury, which may predict recovery and return to play.
Ultrasound-guided injection of steroid and local anesthetic into the muscle tear can speed recovery and subsequent return to play.
Case series; Level of evidence, 4.
Three professional baseball pitchers with acute tears of the internal oblique muscle confirmed by magnetic resonance imaging underwent ultrasound-guided injection of steroid and local anesthetic.
All 3 patients experienced significant pain relief within a few days of the injection and were able to pitch at full speed within 3 weeks of injury (mean, 21 days) and return to able status by 5 weeks (mean, 30.7 days). The 3 athletes continue to pitch in Major League Baseball 36 months, 36 months, and 14 months, respectively, after injury, and none have sustained reinjury during this time.
Therapeutic injection of steroids and anesthetic under ultrasound guidance appears to speed recovery and rehabilitation in professional baseball pitchers with acute side strains.
内斜肌损伤在职业棒球投手中很常见，可能需要长达 10 周的恢复期。大多数拉伤可以通过临床诊断，但影像学检查有助于评估损伤的严重程度，这可能有助于预测恢复和重返赛场的时间。
超声引导下将类固醇和局部麻醉剂注射到肌肉撕裂处可以加速恢复和随后的重返赛场。
病例系列；证据等级，4 级。
3 名经磁共振成像证实患有急性内斜肌撕裂的职业棒球投手接受了超声引导下的类固醇和局部麻醉剂注射。
所有 3 名患者在注射后几天内均明显缓解疼痛，并且在受伤后 3 周内（平均 21 天）能够全速投球，并在 5 周（平均 30.7 天）时恢复正常状态。这 3 名运动员在受伤后分别继续在大联盟棒球比赛中打球 36 个月、36 个月和 14 个月，在此期间均未再次受伤。
在超声引导下进行类固醇和麻醉剂的治疗性注射似乎可以加速急性侧拉伤的职业棒球投手的恢复和康复。
