A and B preaxial polydactyly with syndactyly of feet and hands in the same person--a case report

Surgical management of bilateral preaxial and postaxial polydactyly with syndactyly: A case report

INTRODUCTION AND IMPORTANCE

Polydactyly is the most common congenital malformation in the limbs. However, it is rare for a patient to exhibit concomitant preaxial and postaxial polydactyly alongside syndactyly in both limbs, and there are limited recommendations for such conditions. This report presents a case of bilateral preaxial and postaxial polydactyly with syndactyly of the feet.

PRESENTATION OF CASE

A 2-year-old girl was presented with an excess number of toes on both feet and an abnormal connection between the second and third toes. After a physical examination and plain radiography, the patient was diagnosed with bilateral preaxial and postaxial polydactyly with syndactyly. We performed a one-stage surgical correction consisting of ablation at the extra digit of bilateral great and little toes, followed by syndactyly release using z-plasty. The surgery was uneventful, and the parents were satisfied with the result.

DISCUSSION

A plain radiograph is necessary for pre-operative planning. We discarded the excess digits for cosmetics and soft and hard tissue for optimal function. It is necessary to preserve the soft tissues, remove the auxiliary digit, realign the digit, and restore the ligaments to preserve digit stability.

CONCLUSION

The complexity of this case required a meticulous surgical approach to address the structural abnormalities, restore functionality, and improve cosmetic appearance. In this case, the surgery can be performed in one procedure to minimize patient morbidity.

A rare case of diplopodia and syndactyly: anatomical and surgical considerations

Diplopodia is a rare congenital disorder that has not been extensively discussed in textbooks, and case reports appear to be the main source of information. Although the exact cause of diplopodia remains unknown, the presence of extra digits as well as metatarsals and tarsals allows it to be differentiated from pedal polydactyly. Syndactyly refers to the congenital fusion of the digits. Concomitant bilateral syndactyly and diplopodia is extremely unusual, and in this report we describe a case of right diplopodia and left polydactyly combined with bilateral manual syndactyly in a 15-year-old girl who was ultimately treated with through-the-knee amputation. Radiological examination of the right leg revealed tibial hypoplasia and the right foot displayed 8 digits with corresponding metatarsals and tarsals, whereas the left leg revealed 2 extra digits on the medial aspect of the foot with corresponding metatarsal and tarsal bones. Anatomical dissection of the right foot revealed that it was divided into halves consisting of 8 toes with corresponding metatarsals and tarsals, as well as tibial hypoplasia and absence of the great toe. Diplopodia associated with tibial hypoplasia and syndactyly can be treated surgically, and the present case report details the clinical, radiological, and anatomical elements of this rare deformity.
