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

Completed

• Conditions: Arthroplasty Complications; Anesthesia

• Registration Number: NCT06320691
• Lead Sponsor: Bezmialem Vakif University

Brief Summary

The study compares the effects of various anesthetic techniques on anterior approach total hip arthroplasty results retrospectively

Detailed Description

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.

Primary Outcome Measures

Name	Time	Method
length of hospital stay	from the date of total hip arthroplasty operation until the day that patients discharge, assesed up to 7 days	from date of operation until the date of discharge
stem subsidence	postoperative 1 year	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.
acetabular abduction	postoperative 1 year	abduction degree of acetabular component after surgery
Mean intraoperative estimated blood loss	from preoperative session to postoperative 1 day	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)
mean duration of surgery	from preoperative session to postoperative 1 day	Duration of total hip arthroplasty surgery for each patient
stem varus/valgus degrees	postoperative 1 year	varus or valgus angulation of femoral stem after surgery
