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+/-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+/-3.3% and 80.4+/-3.3 degrees. This measures appear to be a useful measure for determining AP ankle alignment.
