Application of non-cement femoral stem in total hip revision

Objective To discuss the application of non-cement femoral stem prosthesis in total hip revision. Methods A review of 108 patients with revision hip arthroplasties and periprothetic infection using long non-cement femoral stem was made from May 2008 to Aug.2013. The records included intraoperative fractures, osteotomy, distal femural windows and femoral strength line. The hip function was assessed by using Harris score. The preoperative and postoperative hip pain was assessed by using Visual Analog Scale (VAS). The stability of the prosthesis, bone healing and bone ingrowth were determined according to X-ray in postoperative regular follow-up. Results The patients were followed up with a mean period of 6 months to 5 years (mean 33.4 months). Postoperative X-ray evaluation of the prosthesis was in place, bone ingrowth appeared in 3-6 months, bone healing and bone ingrowth was in good condition in six months or more, no signs of periprothetic infection were found, the patients walked well without prosthesis dislocation, fracture and prosthesis loosening. Preoperative Harris score was (48.76±13.17), pain VAS was 4.00(3.00, 6.00). At last time of follow-up, Harris score was (87.11±6.69), VAS score was 0.00(0.00, 1.00), There were significant differences compared with preoperative (all P values<0.05). Conclusions Long non-cement femoral stem has certain advantages in femoral revision and good effect on patients who have defects in the proximal portion of the femur.
