This study examines radial errors in prosthetic sockets, highlighting the clinical implications for reduction, shaping, or enlargement. The research considers the impact on sizing and shaping changes for sockets with varying mean radial errors. The analysis sheds light on when errors become clinically apparent in socket manufacturing.

Figure 4. Example radial error results. (a) Socket with mean radial error (MRE) > 0.25 mm clinically deemed in need of reduction and possibly shaping change (2/e). (b) Socket with MRE > 0.25 mm clinically deemed in need of enlargement and possibly shaping change (7/a). (c) Socket with MRE ≤ 0.25 mm deemed in need of sizing and possibly shaping change (10/b). x- and y-axes are radial and vertical distances, respectively, in mm. Scale range is -1.0 mm to +1.0 mm.
