The uptake of [99mTc]MDP in metastatic lesions of the vertebrae was compared with the uptake in normal vertebrae. The ratio of these lesion-to-nonlesion uptakes at 4 and 24 hr was called the 24-hr/4-hr ratio (TF ratio). A similar ratio was measured for lesions in the spine due to degenerative bone disease. Lesions in vertebrae with degenerative bone disease and treated metastases had a significantly lower TF ratio than lesions in vertebrae with untreated bone metastases. These findings suggest that the TF ratio might be a reliable method for separating metastatic lesions from degenerative changes in the vertebral column, and could be especially useful in cancer patients whose bone scans demonstrate a single lesion in the spine.

Unearthing the Unexpected: First Report of Ossa Cordis in a Human Heart.
Am J Forensic Med Pathol
January 2025
From the Department of Pathology, Wake Forest University School of Medicine, Winston-Salem, NC.
The ossa cordis (OC), or cardiac bone, is a bony structure within the cardiac skeleton of mammals, believed to maintain heart shape during systole and enhance contraction efficiency. Found in large mammals, especially ruminants, and has recently been described in chimpanzees; however, OC has not previously been described in humans. Herein, we present an incidental finding of OC in the heart of a 39-year-old man who suffered a stab wound to chest.

To systematically evaluate the differences in the clinical efficacy of lumbar degenerative disorders (LDDs) treatment between oblique lumbar interbody fusion with percutaneous pedicle screw fixation (OLIF-PF), OLIF stand-alone (OLIF-SA), and OLIF with anterolateral screw fixation (OLIF-AF). A systematic search was conducted on both English and Chinese databases, wherein the literature was screened based on title, abstract, and full text. Literature that met the inclusion criteria was assessed for quality and relevant information was extracted.

Global Spine J
January 2025
Department of Science, Research and Education, BG Klinikum Bergmannstrost Halle, Halle, Germany.
Study Design: Multicenter, prospective observational cohort study.
Objectives: 109 patients with lumbar spine stenosis (LSS) undergoing minimally invasive decompression in 6 different centers (Germany, Italy, USA).
Methods: The demographic, surgical and clinical data was collected.
Background: To compare the effect of minimally invasive and open transforaminal lumbar interbody fusion (TLIF) approaches in fusing the L4-L5 segment and predicting the potential risk of adjacent segment degeneration (ASD).
Methods: A computed tomography scan image was processed and the three-dimensional model of the L1-L5 spine was reconstructed. The minimally invasive and Open TLIF finite element models were constructed.
Anterior cervical discectomy and fusion with self-locking standalone cage for the treatment of cervical degenerative disc disease in patients over 80 years.

Department of Orthopaedic Surgery, Zhongshan Hospital, Fudan University, 180 Fenglin Road, Shanghai, 200032, China.
Background: The need for anterior cervical discectomy and fusion (ACDF) for cervical degenerative disc disease (CDDD) will probably grow dramatically in the geriatric population. However, ACDF with self-locking standalone cages in patients over 80 years has not yet been investigated. This study aimed to assess the clinical and radiographic results in patients over 80 years treated by ACDF with self-locking standalone cages.
