Objective: To evaluate the early clinical efficacy of robot-assisted percutaneous short-segment bone cement-augmented pedicle screw fixation in the treatment of stageⅡ-Ⅲ Kümmell disease.

Methods: The clinical data of 20 patients with stageⅡ-Ⅲ Kümmell's disease who underwent robot-assisted percutaneous bone cement-augmented pedicle screw fixation between June 2017 and January 2021 were retrospectively analyzed. There were 4 males and 16 females, aged from 60 to 81 years old with an average age of (69.

Bone Mineral Loss at the Distal Femur and Proximal Tibia Following Spinal Cord Injury in Men and Women.

Purpose: Spinal cord injury (SCI) causes rapid bone loss and increases risk of fragility fractures in the lower extremities. The majority of individuals with SCI are men, and few studies have investigated sex as a biological variable in SCI-induced osteoporosis. This cross-sectional study aimed to quantify sex-specific differences in bone mineral following SCI.

The Potential Roles of Ferroptosis in Pathophysiology and Treatment of Musculoskeletal Diseases-Opportunities, Challenges, and Perspectives.

Ferroptosis is different from other forms of cell death, such as apoptosis, autophagy, pyroptosis, and cuproptosis, mainly involving iron metabolism and lipid peroxidation. Ferroptosis plays an important role in various disease, such as malignant tumors, neuron-degenerative diseases, and cardiovascular diseases, and has become the focus of current research. Both iron overload and lipid peroxide accumulation contribute to the occurrence, development, and treatment of musculoskeletal diseases, such as osteoporosis, osteoarthritis, osteosarcoma, intervertebral disc degeneration, and spinal cord injury.

Development of a Metaphyseal Non-Union Model in the Osteoporotic Rat Femur.

The aim of this current study was to establish a metaphyseal femoral non-union model in osteoporotic rats by comparing a power tool versus a manual tool for fracture creation. Twelve adult female Sprague Dawley rats were ovariectomized (OVX) and received a special diet for 6 weeks. Biweekly pQCT measurements confirmed a significant reduction in the cancellous and total bone mineral density in OVX rats compared to control (CTRL) animals.

Pharmacologic and Nonpharmacologic Treatment Modalities for Bone Loss in SCI - Proposal for Combined Approach.

Increased risk of bone fracture due to bone mineral density (BMD) loss is a serious consequence of spinal cord injury (SCI). Traditionally, pharmaceutical approaches, such as bisphosphonates, have been prescribed to prevent bone loss. However, there is controversy in the literature regarding efficacy of these medications to mitigate the drastic bone loss following SCI.

Regional and temporal variation in bone loss during the first year following spinal cord injury.

Osteoporosis is a consequence of spinal cord injury (SCI) that leads to fragility fractures. Visual assessment of bone scans suggests regional variation in bone loss, but this has not been objectively characterised. In addition, substantial inter-individual variation in bone loss following SCI has been reported but it is unclear how to identify fast bone losers.

Wiltse transforaminal thoracic interbody fusion approach for the treatment of single‑segment thoracic spinal tuberculosis in elderly patients with osteoporosis: A retrospective study of 20 cases.

The aim of the present study was to investigate the clinical feasibility and efficacy of the Wiltse approach and TTIF in elderly patients with single-segment thoracic tuberculosis (SSTTB) complicated with osteoporosis and neurological dysfunction. Between January 2017 and January 2019, 20 elderly patients underwent the Wiltse TTIF approach at a single hospital. The follow-up time of these patients was 37.

Computed tomography predictors of adult spinal cord injury without radiographic abnormality.

Objective: Elasticity of the skeletal system in children and degenerative changes in adults are responsible for SCIWORA. The purpose of this study was to determine those degenerative changes on CT scan that predispose adults to SCIWORA, their correlation with MRI findings, clinical presentation and recovery.

Materials And Methods: This prospective study was conducted over a period of 1.

Humans at the dawn of the in-body electrical nerve stimulation era.

Background: The neuroprosthesis laparoscopic implantation technique for electric pelvic nerve stimulation was introduced to gynaecology over 15 years ago to treat intractable pelvic neuropathic pain. Following this first indication, other applications were developed, particularly in parapleology. The LION procedure developed to assist patients with paraplegia and common problems associated with inertia when confined to a wheelchair could find revolutionary applications in aging medicine and prevention.

Rehabilitation Towards Functional Independence in a Patient With Intertrochanteric Fracture and Paraplegia: A Case Report.

Traumatic spinal cord injury (SCI) causes significant neurological deficits that adversely affect the quality of life of patients and caregivers. Patients with SCI present with the symptoms of weakness and loss of sensations in the limbs. Motor deficits may occur in the form of paraplegia, hemiplegia, or quadriplegia.

Novel evaluation indicators of MOG induced experimental autoimmune encephalomyelitis in C57BL/6J mice.

Multiple sclerosis (MS) is an autoimmune disease of the central nervous system (CNS), characterized by demyelinating neuropathy. Despite a long period of research on the immune mechanisms involved in CNS diseases, the etiology of MS remains unknown. MS may present with different clinical and pathological manifestations due to the involvement of different pathogenic processes, including balance and mobility disorders, psychiatric abnormalities, and intestinal dysfunction.

Contributions of Resin Cast Etching to Visualising the Osteocyte Lacuno-Canalicular Network Architecture in Bone Biology and Tissue Engineering.

Recent years have witnessed an evolution of imaging technologies towards sophisticated approaches for visualising cells within their natural environment(s) and for investigating their interactions with other cells, with adjacent anatomical structures, and with implanted biomaterials. Resin cast etching (RCE) is an uncomplicated technique involving sequential acid etching and alkali digestion of resin embedded bone to observe the osteocyte lacuno-canalicular network using scanning electron microscopy. This review summarises the applicability of RCE to bone and the bone-implant interface.

Bioactive role of vitamins as a key modulator of oxidative stress, cellular damage and comorbidities associated with spinal cord injury (SCI).

Spinal cord injury (SCI) cause significant disability and impact the quality of life of those affected by it. The nutritional status and diet are fundamental to diminish the progression of complications; vitamins modulate the inflammatory response and oxidative stress, promote blood-spinal cord barrier preservation and the prompt recovery of homeostasis. A deep knowledge of the benefits achieved from vitamins in patients with SCI are summarized.

Comparison of DXA-based versus CT-based indices to predict prevalent fracture history in men with spinal cord injury.

Unlabelled: Fracture risk prediction remains challenging in adults with spinal cord injury. Here, we compare the ability of CT- and DXA-derived indices to discriminate between those with and without prevalent osteoporotic fracture. Novel CT-derived indices may offer improved assessment of fragility fracture risk as well as improved monitoring of response to therapies.

Cervical Spine Fracture with Extreme Dislocation in a Patient with Ankylosing Spondylitis: A Case Report and Systematic Review of the Literature.

Background: Ankylosing spondylitis (AS) is a seronegative arthropathy which results in pathological ossification of the ligaments, disc, endplates and apophyseal structures. Cervical spinal fractures are more common in patients with ankylosing spondylitis than in patients without ankylosing spondylitis due to coexistent osteoporosis and kyphotic alignment of the spine. The risk of fracture-dislocation and associated spinal cord injury is also more in these patients.

Bisphosphonates Alleviate Bone Loss in People with Acute Spinal Cord Injury：A Systematic Review and Meta-Analysis.

Objective: Bone loss is not to be underestimated in people with acute spinal cord injury (SCI). Bisphosphonates can inhibit the bone resorption of osteoclast. To study whether the early application of bisphosphonates can alleviate bone loss after acute SCI, we included 7 randomized controlled trials for meta-analysis.
