3D Biometrics for Hindfoot Alignment Using Weight Bearing Computed Tomography: A Prospective Assessment of 249 Feet

  • Chapter
  • First Online:

Abstract

The foot ankle offset (FAO) is a recently introduced 3D biometrics, using WBCT and semiautomatic software. We prospectively assessed its clinical relevance and reproducibility for hindfoot alignment (HA). FAO and hindfoot angles (HACT) were measured on 249 feet. Mean values for FAO and HACT were 1.17 and 3.18, in normals, 8.10 and 9.69 in valgus, and −6.64 and −8.15 in varus. Intra-/interobserver reliability was 0.987/0.988 for FAO and 0.949/0.949 for HACT with good linear correlation (R2 = 0.744). FAO was reproducible and correlated well with physical examination.

Based on Zhang JZ, Lintz F, Bernasconi A; Weight Bearing CT International Study Group, Zhang S. 3D biometrics for hindfoot alignment using weightbearing computed tomography. Foot Ankle Int. 2019;40(6):720–726.
