Abstract
Disclosed herein are methods, compositions and tools for repairing articular surfaces repair materials and for repairing an articular surface. The articular surface repairs are customizable or highly selectable by patient and geared toward providing optimal fit and function. The surgical tools are designed to be customizable or highly selectable by patient to increase the speed, accuracy and simplicity of performing total or partial arthroplasty.
Claims71
A patient-specific surgical tool for use in surgery on a hip joint of a patient, comprising:
- a block having a patient-specific surface and a guide;
- the patient-specific surface being substantially a negative of a corresponding surface portion of the hip joint that includes an osteophyte;
- the guide being sized to accommodate a surgical instrument and have a position and orientation relative to the patient-specific surface to provide a predetermined path for the surgical instrument that is aligned through a portion of tissue of the hip joint.
A surgical tool for use in surgically replacing or resurfacing a hip joint of a patient, comprising:
- a block having a patient-specific surface and a guide;
- the patient-specific surface having a first portion that is substantially a negative of a corresponding portion of a surface associated with the hip joint and a second portion that is configured to substantially avoid contact with one or more osteophytes of the joint when the first portion is engaged and aligned with the corresponding portion of the surface of the hip joint;
- the guide being sized to accommodate a surgical instrument and have a position and orientation relative to the patient-specific surface to provide a predetermined path for the surgical instrument that is aligned through a portion of tissue of the joint when the first portion is engaged and aligned with the corresponding portion of the surface of the hip joint.
A surgical tool for use in surgically repairing a hip joint of a patient, comprising:
- a block having a patient-specific surface and a guide;
- the patient-specific surface having a first portion that is substantially a negative of a cartilage surface of the joint and a second portion that is substantially a negative of an osteophyte of the hip joint;
- the guide shaped to accommodate a surgical instrument for cutting or drilling or reaming or burring and have a position and orientation relative to the patient-specific surface to provide a predetermined path for the surgical instrument that is aligned through a portion of bone of the hip joint.
A surgical tool for use in surgically repairing a hip joint of a patient, comprising:
- a block having a patient-specific surface and a guide;
- the patient-specific surface having a first portion that is substantially a negative of at least a portion of surface of an acetabular rim of the hip joint including an osteophyte;
- the guide shaped to accommodate a surgical instrument for cutting or drilling and have a position and orientation relative to the patient-specific surface to provide a predetermined path for the surgical instrument that is aligned through a portion of bone of the hip joint.
A surgical tool for use in surgically repairing a joint of a patient, comprising:
- a block having a patient-specific surface and a guide to accommodate a surgical tool;
- the patient-specific surface having at least a portion that is substantially a negative of a hip joint surface of the patient that includes an osteophyte;
- the guide having a position and orientation relative to the patient-specific surface to provide a predetermined path for cutting or drilling when the patient-specific surface is placed against the joint surface of the patient such that the guide has a predetermined alignment relative to an anatomical or biomechanical axis of the patient's hip joint.
