"Ankle fusion procedure" refers to a surgical procedure that seeks to immobilize an ankle joint of a patient. The surgery fuses two or more bones of the ankle of the patient. The surgery involves the use of screws, plates, medical nails, and other hardware or fasteners to achieve bone union. Ankle fusion is considered to be the gold standard for treatment of end-stage ankle arthritis. Ankle fusion trades joint mobility for relief from pain. (Search "ankle fusion" on Wikipedia.com Dec. 21, 2022. CC-BY-SA 3.0 Modified. Accessed June 28, 2023.) An ankle fusion procedure may also be referred to as ankle arthrodesis, talocrural joint fusion, tibiotalar arthrodesis, and tibiotalocalcaneal arthrodesis. An ankle fusion procedure can be performed using a variety of approaches to the ankle including an anterior approach, a posterior approach, a lateral approach and a medial approach. Each approach may use common or different instrumentation or implants for the procedure. |

"Predetermined Position" refers to a position that is decided, determined, finalized, and/or defined earlier in time. In certain embodiments, a predetermined position is a desired, designed, and/or engineered position of a first object in relation to a second object. Thus, a predetermined position is a planned position for the two objects in relation to each other. In certain embodiments, one or both of the two objects may be moved relative to each other to accomplish the predetermined position and the predetermined position may become the final position. In other embodiments, the two objects may be moved towards the predetermined position but may not reach the exact predetermined position due to some impediment and/or interference or a decision to change the predetermined position to a new position. In certain aspects, a predetermined position may be a position that is decided after a process of recommendation, review, and/or analysis, and final approval such that a position may not become a predetermined position until the process is completed. For example, in a medical patient-specific instrument or technique design process a position may not become the predetermined position until a surgeon or other doctor provides final approval for the position. |
