Polydactyly is considered either the most or second most (after syndactyly) common congenital hand abnormality. Polydactyly is not simply a duplication; the anatomy is abnormal with hypoplastic structures, abnormally contoured joints, and anomalous tendon and ligament insertions. There are many ways to classify polydactyly, and surgical options range from simple excision to complicated bone, ligament, and tendon realignments. The prevalence of polydactyly makes it important for orthopedic…

Reconstruction of Thumb Polydactily: A Case Report
A case of polydactyly, the patient had bone exicision of the duplicates when the patient was four-month-old, but that extra metacarpal with no phalanges resulted in a greater space of finger 1 and 2, which is a common congenital hand occurrence.

A Case Report of a Complex Form of Hand Pre-Axial Polydactyly
Surgical excision is the preferred choice of method for most types to stabilize the thumb by making it well-aligned for proper functioning, however, most of corrected digits will be thinner, shorter, and stiffer.

Harvesting a pedicle flap from a severed thumb is a safe and reliable procedure and defects of the preserved thumb, such as the skin, nail, and bone, can be effectively restored using the complex tissue flap.
Outcomes of reconstruction of polydactyly among children in a tertiary health facility in China
Congenital polydactyly of both hands and feet is rare and complex, but as long as the timing and method of operation are properly chosen, bothhands and feet can acquire good appearance and functions after operation.
Long-Term Outcomes After Treatment for Type B Ulnar Polydactyly
While ligation and surgical excision result in similar function and esthetics, patient satisfaction is higher after surgery, advising parents of patients with type B ulnar polydactyly should include these considerations to assist them in selecting the best treatment for their child.
