There are a myriad of socket designs for the individual with transradial or wrist disarticulation level amputation. Progressive socket designs incorporate anatomic contouring to improve comfort, stability, suspension, range of motion, and, ultimately, function. Advancements in materials science have contributed to the continuing evolution of these designs. The progressive upper extremity practitioner should possess an understanding of the spectrum of socket designs and material characteristics to effectively address an individual's unique physical presentation and occupational goals. Considerations in determining the appropriate socket design include but are not limited to the condition of the residual limb, the control strategy, concomitant issues, and the vocational/avocational goals of the individual. The purpose of this article is to demonstrate how integration of the optimal anatomically contoured socket designs and materials significantly improves rehabilitation outcomes. This will be exemplified through four case studies involving three anatomically contoured socket designs and one elevated vacuum design: 1) a wrist disarticulation level flexible thermoplastic suction socket with micro expulsion valve, 2) a transradial anatomically contoured socket with three quarter modification using flexible thermoplastic, 3) a transradial anatomically contoured socket with three quarter modification using injected silicone and 4) a transradial level socket using elevated vacuum suspension.
