Abstract:
Objective To observe the effect of pressure-protective brace with pressure-sensitive device in the early stage rehabilitation training enhance bone healing, shorten the treatment course and reduce complications,a kind of independently developed pressure-protective brace with pressure-sensitive device was utilized with quantified discontinuous longitudinal stress stimulation under doctors' regulation according to procedure. Methods The pressure-protective brace with pressure sensitive device for rehabilitation training was developed in May 2008 ,and was applied in clinics during January 2009 to June 2010. Forty elder patients,with complete clinical data, underwent Dynamic Hip Screw (DHS) internal fixation of femoral intertrochanteric fracture were were enrolled into this study. These cases were assigned into experimental group and control group with 20 patients respectively. The patients of experimental group performed lower extremity rehabilitation training wearing the pressure-protective brace. The load training of lower extremities with double crutches was modulated by doctors through regulating the threshold value of pressure in different time and different condition after operation according to the prearranged rehabilitative plan of individuation. The controls were instructed to performed lower extremity rehabilitation training in traditional way. Both the clinical healing and bone union time in all cases were evaluated according to the uniform standard. Results Total 40 patients were followed up for 13.0 - 24. 0 weeks ( average, 17.6 weeks ). Clinical healing time was 7.0 - 12. 0 weeks ( average,9. 1 weeks ) and bone healing time was 12. 0 - 16.0 weeks(average,13. 7 weeks)in experimental group. While in control group,the clinic healing time and bone union time was 9. 0 - 13.0 weeks( average, 11.3 weeks) and 14. 0 -20. 0 weeks (average, 16. 6 weeks)respectively. The Independent T-test results showed that whether clinic healing time or bone healing time presented significant differences between experimental group and the controls( P＜0. 01 ). All of the fractures in these two groups were healed at the end time of follow up without adverse complications,including fracture displacement, implant break, implant loose and failure. Conclusion The pressure-protective brace with pressure sensitive device used for quantifying rehabilitation training can enhance bone union, shorten the treatment course and reduce complications. This method further proves that discontinuous compressive stress in a certain range can stimulate fracture healing.
