1. A patient-specific orthopedic guide comprising:
- a three-dimensional contact surface preoperatively configured from medical scans of a specific patient as a negative surface of a lesser trochanter of a proximal femoral bone of the patient according to a preoperative surgical plan for the patient;
a planar surface configured for guiding a resection of a femoral neck of the patient, the planar surface configured to be disposed proximal of the lesser trochanter of the patient and configured to extend along less than an entirety of the femoral neck; and
a scale on the planar surface.

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.
