A multicenter intertrochanteric fracture study in the elderly: Hemiarthroplasty versus proximal femoral nailing.

OBJECTIVES

This study aims to compare the clinical and functional results of intertrochanteric femoral fractures treated with bipolar hemiarthroplasty (BHA) or proximal femoral nailing (PFN) in elderly patients.

PATIENTS AND METHODS

This multicenter, prospectively followed-up, retrospectively compared cohort-type study included 308 patients (81 males, 227 females; mean age 78.4±7.2 years; range, 65 to 95 years) who were treated with BHA or PFN for intertrochanteric fractures by five orthopedic surgeons in four provinces and seven clinics between January 2014 and May 2018. Clinical follow-up was performed at third week, third and sixth months, and at the end of the first and second years. The American Society of Anesthesiologists for preoperative status, Singh index for bone quality, and Harris Hip Score (HHS) for functional outcomes were evaluated.

RESULTS

While 156 patients (38 males, 118 females; mean age 77.7±5.9) were treated with BHA, 152 patients (43 males, 109 females; mean age 79±6.1) were treated with PFN. While there was no significant difference between the two groups in terms of total HHS, a significant difference was found in the sub-parameters (p<0.001). Good and excellent results were found in 78.2% of BHA and 86.2% of PFN patients. Mortality rates were similar at the end of two years (14% and 13.6%, respectively).

CONCLUSION

In general, clinical and functional outcomes of BHA and PFN are similar. The rates of pulmonary embolism and deep vein thrombosis are significantly higher in BHA. However, BHA is advantageous in terms of operation time and early weight bearing compared to PFN.
