摘要： A sinus-canalis internal-fixation device is configured in a shape modeled after the anatomical form and dimensions of a sinus tarsi of an ankle-bone structure of a patient, which anatomically twists and curves and is surrounded by the anatomically irregular surfaces of the talus (ankle bone) and calcaneus (heel bone). The surfaces of the sinus-canalis internal-fixation device mirror the anatomically irregular surfaces of the talus (ankle bone) and calcaneus (heel bone) surrounding the sinus-canalis internal-fixation device. The sinus-canalis internal-fixation device comprises an anatomical shaft and anatomical superior, inferior, and posterior pegs connected to the top, bottom, and back end of the anatomical shaft, respectively. Further, if desired, the sinus-canalis internal-fixation device can be cannulated and/or comprise at least one groove, recess, opening, ridge, and/or hill integrated thereinto. The sinus-canalis internal-fixation device can: a) Block the anterior, medial translation and internal, medial rotation of the talus on the calcaneus to obviate limitations in correcting abnormal foot mechanics, b) Distribute the body weight of the patient over a maximum contact area between the sinus-canalis internal-fixation device and the talus (ankle bone) and calcaneus (heel bone), c) Absorb the shocks caused by the body weight of the patient, d) Create coupling-force affect to prevent superior and inferior togglings of the sinus-canalis internal-fixation device within the sinus tarsi to eliminates the problem of displacement and failure of the sinus-canalis internal-fixation device, e) Correct an anatomically deformed alignment of the ankle-bone structure, f) Maintain the ankle-bone structure in an anatomically correct alignment, and g) Eliminate the need for having to verify the anatomically correct alignment of the ankle-bone structure with a fluoroscope, and thus eliminate the need for exposing the patient to radiation.
