Advancements in imaging, computing, microscopy, chromatography, spectroscopy and biological manipulations of animal models, have allowed for a more thorough examination of the hierarchical structure and composition of the skeleton. The ability to map cellular and molecular changes to nano-scale chemical composition changes (mineral, collagen cross-links) and structural changes (porosity, lacuno-canalicular network) to whole bone mechanics is at the forefront of an exciting era of discovery. In addition, there is increasing ability to genetically mimic phenotypes of human disease in animal models to study these structural and compositional changes. Combined, these recent developments have increased the ability to understand perturbations at multiple length scales to better realize the structure-function relationship in bone and inform biomechanical models. The intent of this review is to describe the multiple scales at which bone can characterized, highlighting new techniques such that structural, compositional, and biological changes can be incorporated into biomechanical modeling.

Keyhole decompression surgery for holospinal epidural abscess: a novel approach for spinal stability preservation.
Eur Spine J
January 2025
Department of Orthopaedic Surgery, Graduate School of Medicine, Chiba University, 1-8-1 Inohana, Chuo-ku, Chiba, 260-8670, Japan.
Purpose: Spinal epidural abscesses are rare yet serious conditions, often necessitating emergency surgical intervention. Holospinal epidural abscesses (HEA) extending from the cervical to the lumbosacral spine are even rarer and present significant challenges in management. This report aims to describe a case of HEA with both ventrally-located cervical and dorsally-located thoracolumbar epidural abscesses treated with a combination of anterior keyhole decompression and posterior skip decompression surgeries.

Rotator cuff injury (RCI), characterized by shoulder pain and restricted mobility, represents a subset of tendon-bone insertion injuries (TBI). In the majority of cases, surgical reconstruction of the affected tendons or ligaments is required to address the damage. However, numerous clinical failures have underscored the suboptimal outcomes associated with such procedures.

The First Affiliated Hospital of Guangzhou University of Chinese Medicine, Guangzhou, 510405, China.
Objective: This study presents a novel odontoid parameter, the odontoid incidence (OI), to examine the correlation between OI on preoperative cervical sagittal radiographs and 2-year clinical outcomes following short-segment anterior cervical discectomy and fusion (ACDF) in patients with cervical spondylotic myelopathy (CSM).
Methods: A retrospective analysis of the clinical data of 87 patients with CSM who underwent ACDF surgery from January 2018 to December 2023 was conducted. The patients were categorized into a larger OI group (44 patients, OI > 12.
Treatment of a collapse fracture of the anterolateral tibial plateau with a lateral locking plate and the Jail screw technique.

Department of Orthopedics, Nanjing Drum Tower Hospital Group Suqian Hospital, Suqian, China.
Background: To explore the advantages of a lateral tibial locking plate combined with Jail screw fixation in the treatment of anterolateral tibial plateau collapse fracture (ATPCF).
Methods: A retrospective analysis was conducted on patients with ATPCFs admitted to our hospital from February 2019 to February 2023. Twenty-six patients were successfully included, including 15 males and 11 females, with an average age of 58.
Integrative analysis of Ewing's sarcoma reveals that the MIF-CD74 axis is a target for immunotherapy.

Department of Musculoskeletal Tumor, Peking University People's Hospital, No. 11 Xizhimen South Street, Beijing, 100044, China.
Background: Ewing's sarcoma (EwS), a common pediatric bone cancer, is associated with poor survival due to a lack of therapeutic targets for immunotherapy or targeted therapy. Therefore, more effective treatment options are urgently needed.
Methods: Since novel immunotherapies may address this need, we performed an integrative analysis involving single-cell RNA sequencing, cell function experiments, and humanized models to dissect the immunoregulatory interactions in EwS and identify strategies for optimizing immunotherapeutic efficacy.
