ObjectivesThe purpose of the study was to evaluate the efficacy of hemiarthroplasty with minimally invasive direct anterior approach (DAA) for the treatment of femoral neck fracture in elderly patients. We aimed to compare the DAA and the standard anterolateral approach (ALA), assessing multiple peri‑ and post-operative parameters.Design And SettingBetween December of 2015 and May of 2017, patients operated with medial femoral neck fractures using bipolar hemiarthroplasty with DAA or ALA were evaluated. The volume of bleeding and transfusion, postoperative level of pain, mobilisation and functional outcome were assessed retrospectively.ParticipantsPatients between the age of 75 and 85, suffering Garden Type III Pauwels Type III and Garden Type IV medial femoral neck fractures were entered to the study. Patients had no history of anticoagulant therapy; the operation was performed in the first 48 h. All patients received similar postoperative pain management and physiotherapy. The type of implants was determined by the patients' bone morphology and quality.Main Outcome MeasuresThe outcomes of interest were the level of postoperative pain, blood loss, rate of recovery and physiotherapy, altered gait pattern and accuracy of leg length, related to DAA and ALA techniques.ResultsThe 51 patients operated with DAA showed significantly less pain, based on VAS (visual analogue scale), starting of the first postoperative day. Those patients who were subjected to DAA met with the criteria of hospital discharge 1.68 days earlier, compared to ALA patients. The length of leg was accurately set in 21% of ALA vs 54.9% of DAA patients. On the 12th week follow-up, limping was detected only 5.9% of DAA vs 46% of ALA groups. On the postoperative 2nd and 6th weeks, the HHS (Harris Hip Score) was significantly better in patients with DAA, compared to ALA (77 vs 65 and 91 vs 77, p < .05).ConclusionThe bipolar hemiarthroplasty with DAA allows earlier mobilisation, reduced postoperative pain and need for rehabilitation with an overall better functional outcome, compared to ALA. DAA is proven a reliable choice for femoral neck fractures, offering good outcome and faster recovery, similarly to total hip arthroplasties with degenerative arthritis.Copyright © 2020 Elsevier Ltd.
