족관절 기립 측면 사진에서 측정한 경골축-거골비 = Tibial Axis-Talar Ratio Measured on Standing Ankle Lateral Radiographs

다국어 초록 (Multilingual Abstract)

Purpose: To present tibial axis-talar ratio and tibia-ankle surface angle in lateral measured on standing ankle lateral radiographs of adults who did not have specific ankle pathology. Materials and Methods: On Fifty-six radiographs without ankle osteoarthritis and malalignment, radiographic measures were performed with use of a custom dizitizing program based on $PV-WAVE^{(R)}$. AP ankle alignment was quantified by tibia axis-talar ratio (TTR) and tibia ankle surface angle in lateral (TLS angle). The data was compared with previously reported american data and analyzed using a t-test. Results: The average TTR and TLS angle of our series were $33.9{\pm}3.3%$, and no significant difference compared with reported american adults (p=0.152). Conclusion: The T-T ratio and TLS angle measured on standing ankle lateral radiographs of our series were $33.9{\pm}3.3%$ and $80.4{\pm}3.3^{\circ}$. This measures appear to be a useful measure for determining AP ankle alignment.
