Orthopedics

The goal of the UP Health System - Portage orthopedic team is to provide the best possible care right here in the Copper Country. The team works in an integrated- and cooperative-group setting that strives to provide cost-effective care that will return our patients to the quality of life they’re used to.

UP Health System - Portage’s orthopedic team is trained in the preservation, investigation, and restoration of the form and function of the extremities and associated structures by medical, surgical, and physical means.
