Congenital Differences-Reconstruction for Type IV Radial Polydactyly

Reconstruction for Type IV Radial Polydactyly

Pdf Summary

The article discusses the surgical technique for reconstructing type IV radial polydactyly, a condition where a thumb has an extra proximal and distal phalanx. The assessment for surgical reconstruction involves evaluating the thumb's function, size, stability, and the first web space. Reconstruction typically involves removing the smaller thumb (usually the radial thumb) and addressing tendon insertion and joint orientation to re-create thumb stability and alignment. The article mentions that surgical results are usually satisfying, with complications being uncommon. However, additional surgical intervention may be required in the future to address thumb malalignment or instability. The most-utilized classification for radial polydactyly was developed by Wassel in 1969 and has since been modified to include thumbs with a triphalangeal component and triplication. The article also provides a detailed description of the surgical anatomy, indications, contraindications, surgical technique, rehabilitation, and postoperative care for reconstructing type IV radial polydactyly. The article concludes with pearls and pitfalls, as well as potential complications that may arise from the surgery.
