Hyperbaric oxygen therapy treatment as an alternative for a chronic sinus tract after chordoma surgery and radiation.

J Wound Care 2022 May;31(Sup5):S30-S32

Advent Health North Pinellas Wound Healing Institute of Trinity, New Port Richey, FL, US.

Chordoma is a rare form of cancer that forms from the notochord remnants, and affects the skull and the spine. The standard treatment for a sacrococcygeal chordoma is surgery and radiation. Chordoma has a high rate of recurrence and surgery with radiation treatment can leave patients with surgical site complications, such as wounds, fistulas or sinus tracts. Read More

Spinal Dysraphisms: A New Anatomical-Clinicoradiological Classification.

Indian J Radiol Imaging 2021 Oct 11;31(4):809-829. Epub 2022 Jan 11.

Department of Radiodiagnosis, Government Stanley Medical College, Chennai, Tamil Nadu, India.

A Novel Three-Dimensional Computational Method to Assess Rod Contour Deformation and to Map Bony Fusion in a Lumbopelvic Reconstruction After En-Bloc Sacrectomy.

Front Surg 2021 5;8:698179. Epub 2022 Jan 5.

Department of Spine Surgery, Semmelweis University, Budapest, Hungary.

En-bloc resection of a primary malignant sacral tumor with wide oncological margins impacts the biomechanics of the spinopelvic complex, deteriorating postoperative function. The closed-loop technique (CLT) for spinopelvic fixation (SPF) uses a single U-shaped rod to restore the spinopelvic biomechanical integrity. The CLT method was designed to provide a non-rigid fixation, however this hypothesis has not been previously tested. Read More
