The spectrum that encompasses radial polydactyly can be categorized by the Wassel classification. Reconstruction of radial polydactyly depends on the size and quality of each of the thumbs. Most commonly, the ulnar thumb is larger and is maintained, whereas the smaller radial thumb is excised. In a Wassel type 4, after the redundant thumb is excised, the remaining thumb is centralized and aligned, and the radial collateral ligament of the maintained thumb is reconstructed. Other types of radial polydactyly are more complicated and require more complex reconstructions.
涵盖桡侧多指畸形的谱系可根据瓦塞尔分类法进行分类。桡侧多指畸形的重建取决于每个拇指的大小和质量。最常见的情况是，尺侧拇指较大并予以保留，而较小的桡侧拇指则被切除。在瓦塞尔4型畸形中，切除多余的拇指后，将剩余的拇指进行中心化和对齐，并重建保留拇指的桡侧副韧带。其他类型的桡侧多指畸形更为复杂，需要更复杂的重建手术。
