Lunate fractures are rare and usually occur together with other fractures, dislocations, or ligament disruptions. We want to report an acute fresh isolated lunate fracture without additional ligamentous injury fixated with early surgical intervention. A 23-year-old right-hand-dominated male patient was admitted to our hospital after falling from 1.5-meter ladder over right hand’s palmar face. Standard radiographs diagnosed a displaced lunate fracture. In the intraoperative evaluation, it was observed that there was only lunate dislocation, and there was no ligament lesion or other carpal bone pathology. Fracture was fixed with a headless cannulated screw. Radiographs showed bony union at 6-week follow-up. There was no evidence for Kienböck’s disease 6 months after surgery. Case report regarding fresh isolated lunate fracture that results in clinical success with early intervention without developing avascular necrosis as in our report is extremely rare. In conclusion, satisfying results can be obtained in these patients with careful surgical intervention.

极少见的骨折：孤立的新鲜月牙骨折

月牙型骨折很少见，通常与其他骨折，脱位或韧带破裂同时发生。我们想报告一个急性新鲜的孤立性月牙骨折，而没有通过早期外科手术固定额外的韧带损伤。一名23岁右手占主导地位的男性患者从右手掌侧1.5米高的梯子上掉下后入院。标准X射线照片诊断为月牙移位。在术中评估中，观察到只有月牙错位，没有韧带病变或其他腕骨病理。用无头空心螺钉固定骨折。X射线照片显示，在6周的随访中发现了骨性结合。术后六个月没有证据显示肯恩贝克氏病。如本报告所述，关于新鲜孤立的月牙骨折的病例报告极少发生而在不进行无血管坏死的情况下进行早期干预而取得临床成功的案例极为罕见。总之，通过仔细的手术干预，可以使这些患者获得满意的结果。
