A 67-year-old man presented to the emergency department with right forearm complete amputation. His right arm had been caught between heavy machinery during working. He was transported to our hospital by helicopter from the injury scene, which was approximately 70 km away. He had no other injuries, so he was taken to the operating room immediately. The time from injury to the operating room was 1 hour 54 min. The wound was crushed and had many metal fragments (figure 1). After debridement, osteosynthesis and vascular anastomosis were performed. Subsequently, nervous anastomosis was performed, muscles were readapted and tendons were sutured. We used negative pressure wound therapy (NPWT) for skin and soft tissue deficits at the end of the operation. On postoperative day 4, we reconstructed skin and soft tissue by using the free latissimus dorsi muscle flap. We then covered the remaining raw surface area with a split-thickness skin graft. After confirming that the flap and skin graft succeeded, we removed the NPWT device, which had been worn for 19 days. The postoperative course was uneventful. Because the NPWT device had been worn for 19 days, the range of motion (ROM) of his elbow was initially limited. However, the ROM gradually improved because of good effort during rehabilitation. At postoperative 1 month, the patient was transferred to a rehabilitation hospital (figure 2). At postoperative 10 months, the disabilities of the arm, shoulder and hand score were 67. Despite the poor functional ability, the patient was quite satisfied and appreciative.
Limb amputation causes not only loss of physical integrity but also affects an individual’s mental and social well-being and is a significant problem, especially for younger people and the working population.1 The success rate for replantation after major upper extremity amputation is reported in 77%–93%.2 The success rate depends considerably on the grade of damage. The long-term subjective functionality of replanted upper extremities is satisfactory for patients, and patients appear to have adapted to impaired function, even if their functionality is reduced. Despite the significant progress of modern prosthetic devices, high rejection rates are still observed in most traumatic amputation patients. Hence, arm replantation is still believed to be superior to an amputation stump fitted with an appropriate prosthesis.3
Limb amputation has a profound impact on patient’s quality of life and poses a burden on social economy.
The long-term subjective functionality of replanted upper extremities is satisfactory for patients.
