Cervical radiculopathy: open study on percutaneous periradicular foraminal steroid infiltration performed under CT control in 30 patients.

Background And Purpose: Cervical radiculopathy is a common entity that can become unremitting, seriously disrupting the patient's work and social activities. The purpose of our study was to evaluate the feasibility, tolerance, and efficacy of transforaminal periganglionic steroid infiltration under CT control.

Methods: Thirty patients with cervical radiculopathy, despite at least 1 month of appropriate medical treatment, underwent percutaneous periradicular foraminal steroid infiltration under CT control.

Iliopsoas impingement on the acetabular component: radiologic and computed tomography findings of a rare hip prosthesis complication in eight cases.

Objective: To describe the radiographic and computed tomography (CT) scan features of iliopsoas impingement on the acetabular component (IPI) in total hip arthroplasty.

Method: Eight cases of iliopsoas impingement were diagnosed and confirmed by surgical revision. The plain film radiograph findings and CT scan findings were compared with those of two control populations (8 patients with painless total hip prosthesis and 16 patients with other complications confirmed by surgical revision).

Painful infection at the site of hip prosthesis: CT imaging.

Purpose: To prospectively determine the accuracy of computed tomography (CT) in the detection of painful infection at the site of hip prosthesis before surgery.

Materials And Methods: Helical CT examinations of hip prostheses were prospectively performed before surgery after a standard clinical and radiologic examination of 65 patients. CT scans and conventional radiographs were reviewed for periprosthetic bone abnormalities, and CT scans were reviewed for periprosthetic soft-tissue abnormalities (joint distention, fluid-filled bursae, and fluid collection in muscles and perimuscular fat).

[Imaging of complications following hip arthroplasty].

Acute complications include fractures and prosthesis dislocations. Most chronic complications involve mechanical or septic loosening and aggressive granulomatosis. Greater trochanteric pseudarthrosis, periprosthetic soft tissue ossifications or prosthesis conflict with the psoas muscle can also be responsible for groin pain.

Acute osteoporotic vertebral collapse: open study on percutaneous injection of acrylic surgical cement in 20 patients.

Objective: The aim of this study was to determine the efficacy of percutaneous vertebroplasty in treating painful spinal osteoporotic collapse.

Subjects And Methods: Twenty-three cases of vertebral collapse were evaluated with CT and MR imaging to determine osteoporotic origin and recent evolution. Percutaneous vertebroplasties were performed using CT guidance.
