Abstract

PURPOSE: To provide basic data on anatomy of the ankle joint in adults using magnetic resonance imaging as well as to compare measurements with available data of corresponding dimension in the different sizes of the total ankle replacements design (HINTEGRA(R)).
MATERIALS AND METHODS
Magnetic resonance (MR) sagittal and coronal images from one hundred-forty nine were studied. Post traumatic, arthritic, or grossly deformed ankles at any reason were excluded. Lengths, widths of the main parts of this articulation and also the radius of curvature of talar dome were measured in the MR images. Statistical analysis was performed on these measurements.
RESULTS
On MR coronal image data, average tibial width was 30.0+/-4.1 mm and talar width was 27.0+/-3.4 mm. On sagittal image date, average anteroposterior length of the distal tibia was 39.0+/-4.2 mm, average anteroposterior length of the talus was 31.3+/-2.8 mm, and average sagittal radius of curvature of talar dome was 20.1+/-2.9 mm. All measurements in male were significantly larger than in female (p<0.01), but a significant difference according to age was not found.
CONCLUSION
Ankle morphometric data define a basis of size, particularly useful in the design of ankle prostheses.
