We describe successful surgical treatment in a case of L5 unilateral spondylolysis with contralateral pedicle stress fracture that was not resolved by conservative treatment in a high-performing college baseball player. The 20-year-old man presented with left low back pain that stopped his sports activities. Over the previous year, he had experienced a couple of episodes of pain that subsided with cessation of sports but reappeared after a return to sports. Computed tomography and magnetic resonance imaging revealed a right terminal stage pars fracture and a left pedicle stress fracture at L5. The pain originated from the left pedicle fracture, with no pain from the right unilateral spondylolysis. Given that conservative treatment for 1 year had not been effective, we decided on surgical treatment. Bilateral pedicle screws and the smiley face rod method were applied, and both fractures subsequently healed. In the 2 years since the surgery, the patient has returned to sports and has the potential to become a professional player. J. Med. Invest. 67 : 382-385, August, 2020.
我们描述了一例成功的手术治疗，患者为一名表现出色的大学生棒球运动员，其 L5 单侧峡部裂伴对侧椎弓根应力性骨折，经保守治疗无效。这名 20 岁的男性因左腰背痛而就诊，导致他无法进行体育活动。在过去的一年里，他经历了几次疼痛发作，停止运动后疼痛缓解，但恢复运动后又再次出现。计算机断层扫描和磁共振成像显示右侧终末节段峡部裂和 L5 左侧椎弓根应力性骨折。疼痛源于左侧椎弓根骨折，而右侧单侧峡部裂无疼痛。鉴于保守治疗 1 年无效，我们决定进行手术治疗。采用双侧椎弓根螺钉和笑脸棒法，随后两处骨折均愈合。手术后 2 年，患者已重返运动，并有可能成为职业运动员。J.
