Background: Finger injuries caused by green onion cutting machines in Korean kitchens have unique characteristics of an incomplete amputation in which multiple parallel soft tissues and blood vessels are injured in the same form. In this study, we aimed to describe unique finger injuries and to report the treatment outcomes and experiences of performing possible soft tissue reconstructions. Methods: This case series study included 65 patients (82 fingers) from December 2011 to December 2015. The mean age was 50.5 years. We retrospectively classified the presence of fractures and the degree of damage in patients. The injured area involvement level was categorised as distal, middle or proximal. The direction was categorised as sagittal, coronal, oblique or transverse. The treatment results were compared according to the amputation direction and injury area. Results: Of the 65 patients, 35 had a partial finger necrosis and needed additional surgeries. Finger reconstructions were performed through stump revision or local or free flap use. The survival rate was significantly lower in patients with fractures. As for the injury area, distal involvement led to 17 out of 57 patients displaying necrosis and all 5 patients showing the same in proximal involvement. Conclusions: Unique finger injuries caused by green onion cutting machines can easily be treated with simple sutures. Then prognosis is affected by the extent of injury and the presence of fractures. Reconstruction is necessary for finger necrosis owing to extensive blood vessel damage and limitations when making this selection. Level of Evidence: Level IV (Therapeutic) [ABSTRACT FROM AUTHOR]

Replantation of multilevel amputation of the hand requires considerable hospital resources, and the surgical outcomes in older adults have not been described in detail. Thus, replantation for this injury was mostly confined to young patients. Here, we describe the case of a 63-year-old patient with multilevel amputation of the hand in whom replantation surgery was successful with grasp and pinch functions by the last follow-up. We report the clinical, functional, and patient-reported outcomes and discuss the indications. As the patient transfer system and communication technology develops, more patients will arrive at hospitals in a critical time for replantation. Accordingly, hand surgeons should consider offering replantation option for multilevel amputation after evaluating the indications. [ABSTRACT FROM AUTHOR]
