Abstract
Introduction:
Labral repair gives good results on damage in the labral area of the hip, but in cases with extensive labral damage, labral repair is less effective, reconstruction of labral is needed, recently labral reconstruction has been done using the Iliotibial band (ITB), but no one has measured the tensile strength of the ITB. this study intends to measure the ITB tensile strength based on diameter.
Methode:
This is an experimental research, the sample was taken from 8 cadaveric, consisted of 6 cadavercic male sex and 2 cadaveric female sex, the youngest cadaveric age was 25 years and the oldest 63 years with an average age of 47 years. Each cadaver was treated by taking ITB, The ITB were then measured by applying the Hydraulic Servo Pulser tensile test apparatus. ITB was rolled oval and tied with an unabsorbed polyster suture, the ITB which was oval shaped and had been tied with an unabsorbed polyster suture then measured its diameter from 4mm, 5mm, 6mm, 7mm, to 8mm. Samples that have been prepared are measured using a tensile strength gauge to assess ITB tensile strength ranging from 4mm, 5mm, 6mm, 7mm, to 8mm.
Results:
ITB’s tensile strength curve is sigmoid shape , the average tensile strength for all samples is 647 Psi. The larger the sample diameter, the greater the tensile strength it has. The largest tensile strength is obtained in 8 mm diameter, and the smallest tensile strength is obtained in 4 mm diameter.
Conclusion:
ITB is a promising autograft and can be used as an ingredient for the reconstruction of labral.
