Treatment options vary based on the severity of the thumb deformity and the functional impairment of the hand. Patients with hypoplastic thumb type I often have a well-functioning thumb and may require no further intervention, while patients with type II and IIIA may undergo surgical thumb reconstruction that involves releasing the tight web space between the thumb and index finger using a skin graft and stabilizing the metacarpophalangeal (MCP) joint through ligament reconstruction. Patients with type IIIB, IV, and V have a completely absent or severe mal-functioning thumb and require pollicization; a surgical procedure that creates a functional thumb by transferring another finger (usually the index) to the thumb position.

However, it is noteworthy that certain patients with minor functional limitations in their hand may have experienced undiagnosed thumb hypoplasia during their childhood years. These individuals may have successfully adapted to their condition without seeking medical intervention and may express a preference for non-intervention. (As in this case(. Hypoplastic thumb type I is a congenital condition characterized by underdevelopment of the thumb. It is the mildest form among the different types of hypoplastic thumbs. Bilateral thumb hypoplasia with toes hypoplasia is extremely rare. Despite its small size and limited functionality, individuals with type 1 hypoplastic thumbs can still perform most daily activities. However, specialized medical evaluation and potentially surgical intervention may be required to address functional limitations and improve overall hand function.
