  • the values in column B also apply here as actual values. They were measured at the positions of the limb stump mentioned in column A before the prosthetic socket 2 was created.
  • the method according to the invention measured in advance values which the cross sections of the limb stump z. B. 6 cm, 9 cm and 12 cm to later, defined
  • Column C shows which circumferential values at the positions mentioned in column A at the first time of wearing, approximately 3 months after the prosthesis was created, were collectively, possibly based on or related to actual values. At the same time, they indicate which measurements the limb stump of patient P would presumably assume, since they have already applied to a sufficiently large collective, for example by reflecting the changes in the measurements observed over 3 months.
  • FIG. 6 shows a lookup source on the right.
  • Columns C and D show which geometrical data a limb stump has at the positions specified in column A the values in column B at the time of the initial treatment with a prosthesis (e.g. at the time of investigation)
  • geometric data can be determined on the basis of an existing amount of data at the time of the determination.
