Cerebral Palsy-Case: Radial Polydactyly Reconstruction

Case: Radial Polydactyly Reconstruction

Pdf Summary

Radial polydactyly is a condition where a person has extra thumbs on their hand. The most common type is Wassel IV. The surgical reconstruction of radial polydactyly involves constructing one thumb from the best parts of each duplicated thumb. The dominant thumb is preserved, and the parts of the ablated thumb are used to build the new thumb. The alignment of the thumb with reference to bone, ligaments, and tendons is corrected during the reconstruction. <br /><br />There are several principles that guide the surgical reconstruction. The first is preserving the collateral ligaments, which requires creating an osteoperiosteal sleeve for duplications that arise from the joint surface. Another principle is ensuring proper bony alignment, which may require osteotomy if the bones are misaligned. The last principle focuses on the musculotendinous structures, taking into account their location, insertion, and connections.<br /><br />A typical surgical plan for radial polydactyly involves making an incision and then performing the following steps for the metacarpophalangeal (MP) joint: maintaining the ulnar component, releasing and preserving the radial collateral ligament (RCL), excising the radial component, and attaching the RCL to the ulnar component.<br /><br />Overall, surgical reconstruction for radial polydactyly involves preserving the best parts of the duplicated thumbs to create a functioning thumb, ensuring proper alignment of the bones, and considering the location and connections of the musculotendinous structures.
