"Bone condition" refers to any of a variety of conditions of bones of a patient. Generally, a bone condition refers to an orientation, position, and/or alignment of one or more bones of the patient relative to other anatomical structures of the body of the patient. Bone conditions may be caused by or result from deformities, misalignment, malrotation, fractures, joint failure, and/or the like. A bone condition includes, but is not limited to, any angular deformities of one or more bone segments in either the lower or upper extremities (for example, tibial deformities, calcaneal deformities, femoral deformities, and radial deformities). Alternatively, or in addition, “bone condition” can refer to the structural makeup and configuration of one or more bones of a patient. Thus bone condition may refer to a state or condition of regions, a thickness of a cortex, bone density, a thickness and/or porosity of internal regions (e.g. whether it is calcaneus or solid) of the bone or parts of the bone such as a head, a base, a shaft, a protuberance, a process, a lamina, a foramen, and the like of a bone, along the metaphyseal region, epiphysis region, and/or a diaphyseal region. |

As used herein, "implant" refers to a medical device manufactured to replace a missing biological structure, support a damaged biological structure, or enhance an existing biological structure. Often medical implants are man-made devices, but implants can also be natural occurring structures. The surface of implants that contact the body may be made of, or include a biomedical material such as titanium, cobalt chrome, stainless steel, carbon fiber, another metallic alloy, silicone, polymer, Synthetic polyvinyl alcohol (PVA) hydrogels, biomaterials, biocompatible polymers such as PolyEther Ether Ketone (PEEK) or a polylactide polymer (e.g. PLLA) and/or others, or apatite, or any combination of these depending on what is functional and/or economical. Implants can have a variety of configurations and can be wholly, partially, and/or include a number of components that are flexible, semiflexible, pliable, elastic, supple, semi-rigid, or rigid. In some cases implants contain electronics, e.g. artificial pacemaker and cochlear implants. Some implants are bioactive, such as subcutaneous drug delivery devices in the form of implantable pills or drug-eluting stents. Orthopedic implants may be used to alleviate issues with bones and/or joints of a patient's body. Orthopedic implants can be used to treat bone fractures, osteoarthritis, scoliosis, spinal stenosis, discomfort, and pain. Examples of orthopedic implants include, but are not limited to, a wide variety of pins, rods, screws, anchors, spacers, sutures, all-suture implants, ball all-suture implants, self-locking suture implants, cross-threaded suture implants, plates used to anchor fractured bones while the bones heal or fuse together, and the like.
