Objective Humeral fractures fixed by branch locking intramedullary nails(BLIN)were tested for the sake of understanding their biomechanical function,so as to provided the theoretical basis for clinical practice Methods The intensity and rigidity of humeral fracture fixed by the BLIN was compared with that of fracture fixed by three kinds of other internal fixations in pull test,compress test,bend and torsion test In the expariment,18 pieces of moist fresh humeri were used Results In pull and compress test,the high level of break load of BLIN was close to that of both-ends transverse-interlocking intramedullary nail(TLIN) But the rigidity of BLIN was lower The force of anti-torsion and anti-bend of BLIN was more powerful than that of 6TCP The biomechanical function of three Ender nails(E3) was the poorest Conclusion With the lower stress-shelter rate,BLIN is a kind of organic combination which is characteristic of strong and elastic dynamic fixational function It is beneficial to early exercise and fracture healing after operation
