Background
The minimally invasive direct anterior approach (MDAA) has been reported to be useful in total hip arthroplasty. The benefits of this approach may be useful for the treatment of femoral neck fractures. Aim of this study is to compare MDAA and postero-lateral approach (PLA) in patients treated with hip hemiarthroplasty for femoral neck fractures.
Materials and methods
Between 2013 and 2014, 109 patients underwent bipolar hip hemiarthroplasty for femoral neck fracture: 88 female and 21 male with a mean age of 88 years old. PLA was performed in 54 cases and MDAA in 55 cases.
Results
The mean surgery time was significantly lower in MDAA group (P = 0.001). The hemoglobin loss was significantly lower in MDAA group (P = 0.02). The mean postoperative pain was significantly lower in the MDAA group (P = 0.001). The mean hospitalization period was 2 days lower in the MDAA group but with no significant difference between the two groups (P = 0.09). Hip dislocation was higher in PLA cases (7.4 %) than in MDAA cases (1.8 %). Periprosthetic fracture occurred only in one case of PLA. Great trochanter fracture occurred in 1 MDAA cases, while no cases were observed in the PLA group.
Conclusions
Minimally invasive direct anterior approach for hip hemiarthroplasty in elderly people with femoral neck fracture provided significant benefit in the early postoperative period when compared to the postero-lateral approach in terms of surgery time, hemoglobin loss, postoperative pain, time of recovery and dislocation rate.
Level of evidence
Therapeutic study, level IV (case series).
