摘要:
An instrument for controlled delivery of a device to a target area near a defect of a bone is provided. The instrument comprises a guide frame having a plurality of device portals, each portal defining a trajectory. The guide frame further includes visual markers for aligning the guide frame to an anatomical landmark on the bone to be treated. The instrument also includes a holder for releasable attachment with the guide frame. Each device portal is configured to provide accurate and controlled delivery of the device to the target area. In one example, the markers are radiopaque, and are visualized through fluoroscopy. A method of using the instrument is also provided.

A coordinate mapping system is provided for locating a defect in a bone. The system comprises a positioning instrument for controlled delivery of a device to a target site, the instrument comprising a main body and a rail extending from the main body, the rail including a series of indicia corresponding to predefined grid lines, and a template configured to overlay an image of a bone having a defect at the target site, the template including a predefined grid for determining a set of coordinates to locate the target site using the positioning instrument. A method of accessing a target site near a defect in a bone using the radial coordinate mapping system is also provided.
摘要:
Instruments and associated methods are disclosed for treating joints, and particularly bone tissue. One of these instruments may be a positioning instrument for controlled delivery of a device to a target site of the bone tissue being treated. The positioning instrument may comprise a main body extending at one end into an indicator probe for visual determination of a target site of a bone to be treated, and at an opposite end into a handle. A rail extends from the main body. The instrument also includes an alignment guide having a device portal for insertion of a device therethrough, the alignment guide being detachable and movable along a length of the rail. The device may comprise an implant insertion tool, an injection catheter, a cavity creation tool such as a bone drill, for example, or the device may be an implantable device.
摘要:
Devices and associated methods are disclosed for treating bone, and particularly bone tissue at the joints. Disclosed are implantable devices that can be used either alone or in combination with this augmentation or hardening material for the repair of bone defects and which are particularly suited for use at the joints, and even more particularly, suited for use at the subchondral bone level.

摘要:
Instruments and associated methods are disclosed for treating joints, and particularly bone tissue. In general, the embodiments relate to instruments and associated methods for the surgical treatment of a joint, and particularly to a subchondral bone defect at that joint region. More specifically, the embodiments relate to instruments that allow fast, easy, precise, and controllable subchondral delivery to, or removal of materials from, a bone joint being treated.
摘要:
A system and associated instruments for locating, and accurately and controllably delivering, a device to an area sufficiently near a bone defect using anatomical landmarks is provided. The instruments allow the surgeon to navigate to the area around the bone defect quickly and easily, while also facilitating proper insertion of the device. In some embodiments, the defect is located on a femur. Guide instruments having a plurality of device portals are also provided for use as standalone instruments or as accessories to the system. In addition, a protective guide sleeve is provided for the insertion of small diameter devices.
