In simple words: The surgeon moves the big toe to the hand to create a new thumb if the patient's thumb is missing because of an injury or birth defect. Tiny blood vessels, nerves, and tendons are carefully connected to make sure the toe survives and functions as a thumb.

This procedure involves the transfer of the great toe to the hand to reconstruct a missing thumb, often due to trauma or congenital absence.The procedure includes harvesting the great toe, including its blood vessels, nerves, bone, and tendons, from the foot.A bone graft is often utilized. Microsurgical techniques are employed to connect the toe's vascular supply, nerves, and tendons to the recipient site on the hand. The donor site is closed, and the transferred toe is carefully positioned and secured to create the new thumb.

Example 1: A patient sustains a severe crush injury to their hand, resulting in the loss of their thumb.A great toe-to-hand transfer with bone graft is performed to reconstruct functional thumb., A patient is born with a congenital absence of their thumb. A great toe transfer with microvascular anastomosis is employed to create a functional thumb, improving hand function and dexterity., A patient experiences a traumatic amputation of their thumb.Using a combination of autologous bone graft and microvascular techniques, a great toe transfer is performed to restore thumb function and shape.

Preoperative imaging (X-rays, CT scans), operative report detailing surgical steps, including microsurgical anastomoses, postoperative imaging, and follow-up notes demonstrating successful healing and function.

** This is a complex, high-level microsurgical procedure requiring specialized training and equipment.Successful outcomes depend on meticulous surgical technique and postoperative care.
