Combined radiographic and ultrasound evaluations to decipher joint involvement in the hands of patients with systemic sclerosis.

Objective: The objective of this study was to explore the etiologies and contributing factors of synovial and tenosynovial involvement in SSc, as well as to assess the phenotype of patients with these synovial and tenosynovial features.

Methods: 171 SSc patients with hand manifestations (either vascular, skin or joint manifestations) who underwent standard X-rays of both hands and hand ultrasound (US), were included. Two independent evaluators recorded the presence or absence of acro-osteolysis, calcinosis, microcrystalline and degenerative rheumatisms, including osteophytosis on X-Rays.

Safety of Thermosensor Insertion in the Midline of the Spinal Canal Anterior to the Dura: A Cadaveric Study.

Objective: To evaluate the safety of the insertion of a blunt-tip thermosensor inside the anterior epidural space using the trans-osseous route in the dorsal spine and the double oblique trans-foraminal approach in the lumbar spine.

Materials And Methods: A total of 10 attempts were made on a 91 years old human specimen. Thermosensors were inserted under fluoroscopic guidance in the anterior part of the spinal canal using various oblique angulations.

Anatomical basis for ultrasound-guided infiltration of the saphenous nerve in the subsartorial canal.

The present work is aimed studying the visibility and position of the vasto-adductor membrane with ultrasonography and demonstrating that injection performed under this membrane allows to infiltrate the saphenous nerve. It was analyzed with ultrasonography in four cadaveric subjects and in 13 volunteers. This membrane was clearly visible and methylene blue was located underneath it after injection in all cadaveric subjects.

Transosseous Temperature Monitoring of the Anterior Epidural Space during Thermal Ablation in the Thoracic Spine.

Purpose: To present the technique of combined temperature monitoring and hydrodissection of the anterior epidural space during thermal ablation in the thoracic spine.

Materials And Methods: Data from 8 patients were retrieved retrospectively with thoracic spinal metastases located near the posterior wall of the vertebral body. Thermal ablation was performed with temperature monitoring and hydrodissection of the anterior epidural space.
