文摘
The naviculocuneiform articulation is composed of the navicular proximally and the 3 cuneiforms distally. It is not uncommon to perform surgical interventions at this joint for multiple pathologic foot etiologies. To date, no detailed anatomic measurement is available for each cuneiform articulation on the navicular. The purpose of the present study was to present an anatomic description of this complex joint to aid in better surgical understanding and improve surgical outcomes. Ten fresh, frozen, and thawed below-the-knee cadaveric specimens were used for anatomic dissection of the navicular and associated cuneiforms. The height and width were recorded across the largest span of the entire navicular–cuneiform joint complex and each facet. The mean navicular height and width was 19.9 mm and 34.7 mm, respectively. The medial cuneiform facet mean height and width was 19.9 mm and 15.8 mm, respectively. The intermediate cuneiform facet mean height and width was 20.4 mm and 16.9 mm, respectively. The lateral cuneiform facet mean height and width was 17.5 mm and 14.7 mm, respectively. A detailed description of this joint complex will aid foot and ankle surgeons in screw placement and surgical decision-making when performing complex medial column fusions. Advanced 3-dimensional weightbearing computed tomography would give us a better idea of the motion that occurs within this complex joint.
