Preparatory Prosthesis
A temporary prosthetic device fitted during the early rehabilitation phase to allow functional use while the residual limb matures.
Full Definition
A preparatory prosthesis, sometimes called a temporary or interim prosthesis, is fabricated and fitted before residual limb maturation is complete. It allows early ambulation or upper-limb use, accelerates rehabilitation, and provides the clinical team with functional and alignment data to inform the design of the subsequent definitive prosthesis. In clinical documentation, the preparatory prosthesis is billed and coded differently from the definitive device and must be accurately labelled to avoid insurance claim errors. Editors must distinguish this term from 'definitive prosthesis' and ensure consistent use within a single document. Some style guides abbreviate it as 'prep prosthesis' in informal clinical notes.
Usage
Usage note: Do not abbreviate to 'prep prosthesis' in formal clinical or insurance documents. The preferred formal term is 'preparatory prosthesis'.
