The study compares the effects of various anesthetic techniques on anterior approach total hip arthroplasty results retrospectively
Under general (GA) or spinal anesthesia (SA), total hip arthroplasty using the anterior approach (THA-A) can be safely performed. The best method is not sufficiently described in the literature currently in existence.This observational study was carried out at a single facility with consecutive enrollment of patients getting primary THA-A. The investigators compared the difference in complication rates, intraoperative blood loss, length of hospital stay, and duration of surgery, acetabular and femoral component orientation and stem subsidence.

| Measure | Description | Time Frame |
|---|---|---|
| Mean intraoperative estimated blood loss | Total blood volume was calculates according to Nadler's formula based on patient's sex, height and weight of the patient, whereas the estimated blood loss was calculated according to Meunier's formula (mL) | from preoperative session to postoperative 1 day |
| mean duration of surgery | Duration of total hip arthroplasty surgery for each patient | from preoperative session to postoperative 1 day |
| length of hospital stay | from date of operation until the date of discharge | from the date of total hip arthroplasty operation until the day that patients discharge, assesed up to 7 days |
| stem subsidence | Subsidence was evaluated by comparing immediate post-operative radiographic images with those obtained at 1 year follow-up. Subsidence was measured as a vertical drop of stem, characterised by a radiolucent line at the proximal most aspect of the bone-prosthesis interface. | postoperative 1 year |
| stem varus/valgus degrees | varus or valgus angulation of femoral stem after surgery | postoperative 1 year |
| acetabular abduction | abduction degree of acetabular component after surgery | postoperative 1 year |
