Replantation of a Severed Finger in a 9-Month-Old Infant: A Case Report.

This case reports the successful replantation of the distal phalanx of the right index finger in a 9-month-old male infant. The patient sustained a complete distal interphalangeal (DIP)-level amputation due to accidental injury and underwent immediate microsurgical replantation after emergency assessment. The surgical procedure involved meticulous vascular anastomosis and nerve repair, followed by postoperative management, including infection control, anticoagulation, and circulation promotion. A 6-month follow-up demonstrated satisfactory outcomes, with good blood supply, preserved finger contour, and no gross functional impairment. Given the technical challenges of digital replantation in infants and the limited number of such cases reported, this may be among the youngest cases of successful digital replantation to date. This case provides valuable insight into surgical strategies and postoperative care for replantation in very young children.
