Prosthetic Socket Design Software (Lower & Upper Extremity)

The socket is the only part of a prosthesis that touches the patient, and most fit problems start there. In the traditional flow a plaster negative is taken, a positive is cast and the model is corrected by hand: how much material came off where is the technician's decision and is written down nowhere. So when limb volume changes six months later, the revision is rebuilt from scratch rather than on top of the previous decision.

In digital socket design the limb geometry is scanned once and every intervention stays on that model as a parameter. The next socket is produced by comparison with a recorded geometry, not with an estimated difference.

The flow starts by bringing the residual-limb scan into the lower-extremity (LE) or upper-extremity (UE) workspace. In transtibial and transfemoral cases, load-bearing and pressure-relief regions are defined; in transradial and transhumeral cases, proximal flanges, stabilization rings, and edge contours are sculpted. The scan is aligned along its anatomical axis and distal/proximal boundaries are set.

The brim line, medial and lateral heights, and the trimline are edited on screen. Every edit is saved as a version and two versions can be compared side by side, so the answer to 'what did we change last time' stays in the file.

Clinician approval enters at two points in this module: approving the regional load/relief map, and approving the final form before it goes to production. The software proposes; the clinician decides.

The module derives residual-limb length, circumferences level by level, and volume from the scan. Comparing two scans shows volume change as a number — tying socket replacement timing to data rather than estimates.

On the output side, both direct 3D-printable check/definitive socket shells (STL) and CNC positive milling molds for thermoforming workshops are produced. Adjustments made on diagnostic sockets transfer parametrically to definitive devices. Files head to the clinic's 3D printer, CNC carver, or partner manufacturing facility.
