Abstract: A method of orthopedic treatment includes steps of: by using a computer aided design (CAD) tool based on profile data that is related to a to-be-treated part of a bone of a patient, obtaining a model of a preliminary instrument that substantially fits the to-be-treated part; by using the CAD tool, obtaining a model of a patient specific instrument (PSI) based on the model of the preliminary instrument; producing the PSI based on the model of the PSI, the PSI being adjustable; performing medical operation on the to-be-treated part, and then attaching the PSI to the to-be-treated part; after attaching the PSI to the to-be-treated part, adjusting the PSI such that the PSI is adapted to real conditions of the to-be-treated part.

Abstract: The disclosure provides a portable electronic device, including a main body, a side cover, a decorative plate, and an elastic element. The side cover is pivotally disposed on a side edge of the main body. The side cover is movable between a first position and a second position relative to the main body. The side cover abuts against the main body when in the first position. The side cover forms an angle with the main body when in the second position. The decorative plate includes a first edge, a second edge, and a third edge. The first edge is pivotally disposed on the side cover. The second edge abuts against the main body when the side cover is in the first position. The second edge is separate from the main body and the third edge abuts against the main body when the side cover is in the second position. The elastic element is disposed at the second edge. The elastic element supports the decorative plate when the side cover is in the second position.
