Prosthetic Rehabilitation for a Patient With Purpura Fulminans Undergoing Quadruple Amputation: A Case Report

Purpura fulminans (PF) is a rare and life-threatening syndrome characterized by cutaneous purpura resulting from disseminated intravascular coagulation (DIC) and intravascular thrombosis. PF typically develops as a severe complication of infections and is associated with high mortality rates. Effective treatment involves early recognition, aggressive resuscitation, appropriate antibiotic therapy, and the correction of coagulation abnormalities. Nevertheless, despite effective treatment, patients often ultimately require amputation of the affected limbs. This case report details the rehabilitation process of a patient with PF who underwent quadruple amputation. The patient, a 48-year-old male, underwent quadruple amputation due to PF. After intensive care, he was admitted to a convalescent rehabilitation ward for prosthetic rehabilitation. The rehabilitation process combined physical and occupational therapy to facilitate independent living through the use of upper and lower limb prostheses and assistive devices. The patient presented with ulcerative lesions on the anterior surfaces of both knee joints upon admission. During treatment, he developed osteomyelitis of the right patella, which required intravenous antibiotics and limited rehabilitation to bed-based exercises. Following the administration of intravenous therapy, the prosthetist proceeded with the fabrication of lower limb prostheses. Subsequently, the patient was able to commence standing and gait training, and by the time of discharge, he was able to walk without a cane. Upper limb prostheses enabled independence in activities of daily living (ADLs) such as eating, dressing, and toileting. He was also able to perform cooking-related activities that are part of the instrumental activities of daily living (IADLs). This case highlights the importance and achievable outcomes of rehabilitation for patients with PF who have undergone quadruple amputation. A multidisciplinary approach utilizing both upper and lower limb prostheses, as well as assistive devices, enabled significant functional recovery.
