1. An orthopedic device for correcting a bone abnormality comprising:
- a patient-specific three-dimensional shell having an outer surface and an inner bone engagement surface customized in a pre-operating planning stage by computer imaging to closely mate and conform to a bone of a patient in only one position, wherein the entirety of the inner surface is configured to contact the bone; and
a patient-specific guiding feature configured to receive a removal tool such that the removal tool extends through an aperture defined by the inner surface, wherein the patient-specific guiding feature is pre-operatively planned relative to the shell such that when the shell is fitted over the bone, the guiding feature is configured to guide the removal tool for removing an abnormality portion of the bone of the patient.

Abstract
An orthopedic device for correcting a femoral bone abnormality includes a patient-specific three-dimensional shell and a patient-specific guiding feature. The shell has an outer surface and an inner bone engagement surface customized in a pre-operating planning stage by computer imaging to closely mate and conform to and substantially cover a femoral head of a patient in only one position. The guiding feature is pre-operatively planned relative to the shell such that when the shell is fitted over the femoral head, the guiding feature can guide a removal tool for removing an abnormality portion of the proximal femur of the patient.
