Patent Images
1. An orthopedic device comprising:
- a patient-specific guide having;
a three-dimensional contact surface preoperatively configured from medical scans of a specific patient as a negative surface of a medial portion of a proximal femoral bone of the patient according to a preoperative surgical plan for the patient;
a proximal planar surface configured for guiding a resection of a femoral neck of the patient; and
a scale on the planar surface, the scale configured for indicating a preoperatively planned femoral version of a femoral stem implant and deviations therefrom.

Abstract
An orthopedic device includes a monolithic patient-specific guide. The patient-specific guide includes a three-dimensional contact surface preoperatively configured from medical scans of a specific patient as a negative surface of a medial portion of a proximal femoral bone of the patient according to a preoperative surgical plan for the patient. The guide also includes a proximal planar surface configured for guiding a resection of a femoral neck of the patient, and a scale formed on the planar surface. The scale is configured for indicating a preoperatively planned femoral version of a femoral stem implant and deviations therefrom.
