Hand casting is a wrapped impression of your limb and volume. It usually results with a superior fit of the residual limb. Highly customized to each individual. One off! CAD CAM/measurements can be done with measurements or digital scan, and utilizes a pre-determined template socket/shape that can work for the average of the patients. This does not give the clinician as much ability to modify the model or template as you would with an actual “positive” model. They can be effective but often are not detailed to the level of hand cast impressions. If measured only, not likely to result in a superior fit. The practitioner depends on the model template to create a generic model. Be cautious of measurements only to make a socket. Digital scans can be more effective than measurements, but also require a template of the average shape, and cannot accommodate uniqueness of individual amputation.
