BIOMECHANICAL AND HISTOLOGICAL MEASUREMENT OF A BONE-RETINACULUM-BONE AUTOGRAFT
Objective To observe the biomechanical and histological properties of a bone-retinaculum-bone (BRB) autograft.Methods The dorsal aspect of the scapholunate ligament (DSLL) and BRB specimens were harvested from 8 fresh-frozen human cadaveric forearms.The specimens were mounted on a testing machine for biomechanical and histological analyses.The stiffness,maximum force,maximum displacement,maximum stress,and maximum energy of each specimen were calculated.Results The BRB autograft had significantly lower stiffness,maximum force,and maximum energy than the DSLL (t =13.3-14.5,P＜0.05).However,there were no significant differences in the maximum stress or maximum displacement between the BRB autograft and DSLL (P＞0.05).The BRB autograft and DSLL had similar histological properties.Conclusion The BRB autograft may be an appropriatc graft material for scapholunate ligament reconstruction.
