To evaluate the interobserver and intraobserver reliability of various radiographic criteria used to assess tibial shaft fracture healing following intramedullary fixation.
Four orthopaedic trauma surgeons independently evaluated the radiographs of 30 patients with tibial shaft fractures treated by intramedullary fixation across various stages of healing.
Surgeons completed assessments on two occasions separated by eight weeks, evaluating degree of union, number of cortices bridged by callus, visible fracture lines, callus extent/quality, and general healing impression.
Agreement between and within observers was analyzed using quadratically weighted kappa (κ) statistics.
Interobserver agreement was substantial for the number of cortices bridged by callus (κ = 0.75), cortices with visible fracture lines (κ = 0.70), and general healing impression (κ = 0.67), but moderate for the radiological union scale (κ = 0.60) and callus extent (κ = 0.57).
Intraobserver agreement demonstrated near-perfect consistency for the overall impression of healing (κ = 0.89), cortices bridged by callus (κ = 0.82), and cortices with a visible fracture line (κ = 0.83).

Implication

Observer agreement study reveals high reproducibility for cortical bridging in tibial fractures, suggesting a reliable radiographic metric for healing.
