Clinical measurement of intermalleolar distance in Western Indian population

Renu Gupta, Ashish Kumar Nayyar, Surajit Ghatak


Background: Angular deformities around the knee are one of the common basis of presentation at orthopaedic clinic and intermalleolar distance (IMD) is an essential anthropometric tool for evaluation of the angular status of the lower limb.

Methods: 500 healthy (330 male and 170 female) subjects between 20 to 40 years of age were taken for IMD measurement in standing and supine position by digital vernier caliper.

Results: The normal range of IMD in western Indian population in between 32-58 mm. IMD in standing position was 42.47 mm with (95% CI = 40.51 to 44.42 mm) and in supine position was 34.45 mm with (95% CI = 32.78 to 36.13 mm). Mean IMD in male in standing position was 40.01 mm while in female it was 43.74 mm observed. Statically significant difference was observed in posture change and according to age.

Conclusions: Significantly higher value in female, in standing position and in higher age group were observed.
