背景:月骨骨折的发生率非常低,不到所有骨折的1%。月球骨折通常来自高能损伤,常合并其他腕关节骨折。简单的月骨骨折可以用螺钉或克氏针固定。然而,粉碎性月骨骨折难以通过常规方法减少和固定。
方法:在这里,我们报告了一名42岁的男性建筑工人,他被挖掘机铲斗压碎,出现了粉碎性月骨骨折,并伴有桡骨远端骨折和舟骨骨折。
方法:粉碎性月骨骨折,桡骨远端骨折,舟骨骨折.
方法:采用后入路用聚甲基丙烯酸甲酯骨水泥重建桡骨,空心螺钉用于固定舟骨和桡骨远端骨折。
结果:手术后第3个月,右腕关节的运动得到改善。手术后第六个月,患者返回建筑工地,开始以与受伤前相同的强度工作。
结论:尽管粉碎性月骨骨折的发生率很低,它们有时会发生。对于粉碎性月骨骨折,早期识别和干预可以保留腕关节的大部分功能。
BACKGROUND: Incidence of lunate fractures is very low, less than 1% of all fractures. Lunate fractures generally come from high-energy injuries, often combined with other wrist fractures. Simple lunate fractures can be fixed with screws or Kirschner wires. However, Comminuted lunate fractures are difficult to reduce and fixe by conventional methods.
METHODS: Here we report a 42-year-old male construction worker who was crushed by an excavator bucket and presented with comminuted lunate fracture combined with distal radius fracture and scaphoid fracture.
METHODS: Comminuted lunate fracture, distal radius fracture, and scaphoid fracture.
METHODS: The posterior approach was used to reconstruct the radial lunate bone with polymethylmethacrylate cement, and cannulated screws were used to fix the scaphoid and distal radius fractures.
RESULTS: At the 3rd month after surgery, the movement of the right wrist joint improved. At the sixth month after surgery, the patient returned to the building site and began working at the same intensity as before the injury.
CONCLUSIONS: Although the incidence of comminuted lunate fractures is very low, they occur sometimes. For comminuted lunate fractures, early identification and intervention can preserve most of the function of the wrist joint.
