Aims and objectives: The study aimed to evaluate the early results of long stem bipolar cementless hemiarthroplasty for the
treatment of unstable intertrochanteric fractures in senor patients and functional rehabilitation after surgery. Methodology: This
prospective research included 68 intertrochanteric fracture patients aged over 75 years, with type A2 and A3.3 of AO foundation
classification (Arbeitsgemeinschaft für Osteosynthesefragen), treated with long stem bipolar cementless hemiarthroplasty at the 7A
Military Hospital from Jan 2016 to October 2019. Studied patients were monitored and evaluated for three months after the
operation. Results: The average age of the patients was 84 ± 9 years. There were 22 male and 45 female patients. Domestic accidents
accounted for all cases. Two cases had surgical wound infection with retentive mucus; in one case, the femoral stem pierced the
bone cortex, and two cases had ruptured fixation steel suture, one case had pierced cortical bone caused by the femoral stem. No
case resulted in death within the postoperative three months. Remarkably, 56/58 cases (82.4%) had soon resume walking
(postoperative day fourth – day seventh). Functional rehabilitation results (based on Modified Harris scale) were “very good” and
“good” in 89.4% cases, “average” in 8.8% cases, and “poor” in 1.8% cases. Discussion: Long stem bipolar hip replacement was found
to be suitable to treat intertrochanteric fractures in the elderly as it provided fast rehabilitation. Modified Handinger incision
approach and various fixation techniques such as steel cord and stem installment were discussed and proved to be effective. MHHS
showed advantages to be used in Vietnam conditions. Conclusion: Long stem bipolar cementless hemiarthroplasty for the treatment
of unstable intertrochanteric fractures in the elderly was shown to result in good outcomes. The treatment enabled walking and
muscular rehabilitation in the patients, enabled the patients to resume daily activities quickly, reduced care burden, and promoted
life quality for the patients.
