Risk of injury to the femoral blood vessels based on the extent of acetabular dysplasia in total hip arthroplasty

Abstract

We evaluated the course of the femoral blood vessels of patients with acetabular dysplasia. Patients were divided into five groups: those with Crowe type I, II, III, and IV dysplastic hips and those with normal hips. A computed tomography-based hip navigation software was used to measure the distance between the femoral blood vessels and the anterior pelvic wall in four axial planes located 10–40 mm proximal to the pelvic teardrop. In Crowe Groups I through IV, the distance was shortest at a point 20 mm proximal to the pelvic teardrop. Furthermore, the distance decreased as the Crowe classification grade increased. Because the femoral blood vessels pass close to the pelvis in many patients in Crowe III and IV hips, caution is required during surgery in these patients.

Ultrasound‐guided injection of the hip: Cadaveric description for the lateral approach

“…As a result, the needle tip can be partially or transiently out of sight, increasing the risk of injury to vascular elements. In some individuals, the femoral artery and/or its branches can have an anomalous/tortuous course and lie close to the anterior hip joint capsule 15 . In this study, the transverse branch of the lateral circumflex femoral artery was discovered 8 mm anterior to the needle.…”

This distance may not be considered safe in terms of inadvertent injuries.…”

Delayed Femoral Artery Occlusion After Total Hip Arthroplasty via the Posterior Approach: A Single-Case Report From Thailand

“…Concerning the correlation between the course of femoral blood vessels and the extent of acetabular dysplasia, Maeda et al [10] reported the mean shortest distances between vessels and the anterior pelvic wall in Crowe classification type I-IV to be 7.7, 6.7, 5.4, and 4.2 mm, respectively (The mean shortest distance in a normal hip was 7.5 mm.). Riouallon et al [5] proposed that defect of the anterior acetabular wall can make acetabular exposure more difficult and that absence of soft tissue between the femoral artery and the anterior acetabular wall can increase the likelihood of vessel injury caused by the anterior Hohmann retractor.…”
