General vs Spinal Anesthesia for Total Joint Arthroplasty-Anterior Approach: A Single-Institution Observational Study

N/ACompletedNCT06320691

Bezmialem Vakif University437 enrolled

Overview

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.

Outcomes

Primary Outcomes

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)

Time frame: from preoperative session to postoperative 1 day

mean duration of surgery

Duration of total hip arthroplasty surgery for each patient

Time frame: from preoperative session to postoperative 1 day

length of hospital stay

from date of operation until the date of discharge

Time frame: 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.

Time frame: postoperative 1 year

stem varus/valgus degrees

varus or valgus angulation of femoral stem after surgery

Time frame: postoperative 1 year

acetabular abduction

abduction degree of acetabular component after surgery

Time frame: postoperative 1 year
