Objective To discuss and analyze effect of biotype common handle (short handle) prosthesis in treating aged patients with femoral intertrochanteric fracture.Methods A retrospective analysis was carried out on 321 patients,among which 280 (102 males and 178 females,at age of 72-98years,average 82.5 years) obtained follow-up.According to a new fracture classification method (Piansui Classification),the typeⅠ a fracture was found in 65 cases and type Ⅰ b in 215.Most patients were combined with medical diseases,and after related medical collaborative treatment,standard biotype common handle prosthesis (artificial bipolar femoral head) replacement was applied to all patients.Early rehabilitation exercise was performed postoperatively.Results All the 321 patients lived through perioperative period successively,with no death in hospitalization.Meanwhile,postoperative complications were all cured in hospitalization.The patients could take out-of-bed activity at 1-3 weeks after operation.All 280 patients could take care of themselves at 12-46 months (average 28 months) of follow-up.According to Harris score,the results were excellent in 129 cases,good in 121,fair in 22 and poor in eight,with excellence rate of 89.3％.Conclusion Biotype common handle artificial femoral head replacement is an effective method to allow early ambulation,reduce complications and improve quality of life in treatment of intertrochanteric fractures in the elderly.
