Chronic Obstructive Pulmonary Disease-IV: Assessement and Diagnostic Studies01:27

Chronic Obstructive Pulmonary Disease-IV: Assessement and Diagnostic Studies

Assessing and diagnosing Chronic Obstructive Pulmonary Disease (COPD) involves a detailed approach that includes a comprehensive review of medical history, physical examination, and a variety of diagnostic tests. This thorough evaluation is essential to ensure an accurate diagnosis and guide effective management strategies.

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
Herniated Intervertebral Disc l: Introduction01:29

Herniated Intervertebral Disc l: Introduction

Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...

Degenerative Disc Disease I: Introduction

Degenerative disc disease is a chronic condition in which intervertebral discs gradually lose structure and function. It is not infectious or autoimmune; rather, it results from age-related biochemical and mechanical changes, influenced by genetic, metabolic, and environmental factors.Structure and Function of DiscsThe spine contains 23 intervertebral discs that absorb load, distribute forces, maintain spacing, and allow flexibility. Each disc consists of a nucleus pulposus, a gel-like core...
Degenerative Disc Disease ll: Pathophysiology01:23

Degenerative Disc Disease ll: Pathophysiology

The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...

    Area of Science:

    • Orthopedics
    • Hand Surgery
    • Radiology

    Background:

    • Kienböck's disease (KD) is a debilitating wrist condition affecting young manual laborers, leading to pain and functional impairment.
    • Current treatment options for KD vary, with a need for effective, minimally invasive approaches.

    Purpose of the Study:

    • To comprehensively review the clinical, functional, and radiological outcomes of Metaphyseal core decompression (MCD) in patients with Kienböck's disease.
    • To assess the efficacy and safety of MCD across different stages of KD.

    Main Methods:

    • A narrative review of literature published up to November 2024 was conducted.
    • Studies were identified using PubMed, Cochrane Library, Google Scholar, and Web of Science.
    • Eligible articles were qualitatively synthesized, focusing on clinical, functional, and radiological outcomes.

    Main Results:

    • Eighteen studies involving 382 patients (Lichtman stages I-IIIb) were analyzed.
    • MCD demonstrated significant improvements in pain (VAS), function (DASH, MWS, PRWE), and grip strength.
    • High return-to-work rates (91-100%) were observed, with low complication and reoperation rates (4.2-8.3%).

    Conclusions:

    • Metaphyseal core decompression (MCD) is a beneficial treatment for Kienböck's disease, offering pain relief and functional improvement in early and advanced stages.
    • The procedure's minimally invasive nature and lack of implants provide socioeconomic advantages.
    • Further research, including cadaveric studies, may refine arthroscopic MCD techniques for enhanced outcomes.
