PURPOSE: Iliotibial tract friction syndrome (ITBFS) might be caused by repetitive friction and abrasion of the iliotibial (ITB) tract across the lateral femoral epicondyle. Thickening in the ITB adjacent to the lateral femoral epicondyle has been reported. The values of ITB thickness at the lateral femoral epicondyle in healthy adult volunteers were determined, and the association between the thickness of the ITB and the subjects' age, weight, height, dominant limb and the volume of training or sporting activity was assessed. METHODS: An Ultrasound Scan (high resolution 3-2 MHz transducer Voluson-i G E Medical Systems, UK) was used to measure the thickness of the ITB in 38 healthy volunteers (30 men and 8 women, mean age 22.5 ± 1.5 years, range 18-25 years). One measurement from each of the subjects' knees at the level of lateral femoral epicondyle was taken. Reliability was established by measuring 11 of the subjects on three separate occasions at least I week apart. RESULTS: The thickness of the ITB on the right and left knees was 1.1 ± 0.2 mm. There was no evidence of a significant association between the thickness of the ITB and the subjects' age, weight, height, dominant limb and the volume of training or sporting activity. CONCLUSIONS: There is no evidence of significant correlation between the thickness of the ITB and subjects' age, weight, height, dominant limb and volume of training or sporting activity.

Abstract

PURPOSE: Iliotibial tract friction syndrome (ITBFS) might be caused by repetitive friction and abrasion of the iliotibial (ITB) tract across the lateral femoral epicondyle. Thickening in the ITB adjacent to the lateral femoral epicondyle has been reported. The values of ITB thickness at the lateral femoral epicondyle in healthy adult volunteers were determined, and the association between the thickness of the ITB and the subjects' age, weight, height, dominant limb and the volume of training or sporting activity was assessed. METHODS: An Ultrasound Scan (high resolution 3-2 MHz transducer Voluson-i G E Medical Systems, UK) was used to measure the thickness of the ITB in 38 healthy volunteers (30 men and 8 women, mean age 22.5 ± 1.5 years, range 18-25 years). One measurement from each of the subjects' knees at the level of lateral femoral epicondyle was taken. Reliability was established by measuring 11 of the subjects on three separate occasions at least I week apart. RESULTS: The thickness of the ITB on the right and left knees was 1.1 ± 0.2 mm. There was no evidence of a significant association between the thickness of the ITB and the subjects' age, weight, height, dominant limb and the volume of training or sporting activity. CONCLUSIONS: There is no evidence of significant correlation between the thickness of the ITB and subjects' age, weight, height, dominant limb and volume of training or sporting activity.
