Description
Pollicization surgery is a specialized hand and reconstructive procedure used to create or restore a functional thumb when the thumb is absent, severely underdeveloped, or cannot function effectively. During the procedure, another suitable finger—most commonly the index finger—is repositioned and reshaped to perform the essential functions of a thumb.
The thumb plays a vital role in gripping, pinching, holding objects, and fine hand movements. Pollicization aims to improve these important functions by creating a new thumb with appropriate positioning, length, movement, and sensation.
When Is Pollicization Surgery Considered?
Pollicization may be recommended in selected cases such as:
Congenital absence or severe underdevelopment of the thumb
Non-functional or severely damaged thumb
Certain complex hand deformities
Traumatic loss of the thumb when reconstruction with other techniques is not suitable
Conditions where creating a functional thumb can significantly improve hand use
How Does Pollicization Work?
The surgeon carefully transfers and repositions a suitable finger so that it can function more like a thumb. The procedure involves precise adjustment of the bone, tendons, nerves, blood vessels, and soft tissues to achieve useful thumb opposition and grasp.
Because every hand condition is different, the surgical approach is planned according to the patient's age, anatomy, existing hand function, and overall reconstructive requirements.
Recovery & Rehabilitation
After surgery, the hand may require immobilization followed by a structured rehabilitation program. Hand therapy, exercises, and gradual functional training are important for helping the newly positioned digit develop coordinated thumb-like movements.
The overall recovery period varies depending on the complexity of the reconstruction and the patient's individual condition.
Pollicization is a highly specialized reconstructive procedure that focuses not only on appearance but, importantly, on restoring practical hand function and improving the ability to perform everyday activities.
