Detachable 4 Stage Pathological Lumbar Spine Model with Instruction Card, Diseased Lumbar Spine Comparison Model Display Herniated Disc for Orthopedic Teaching

This 4-stage lumbar spine model represents a breakthrough in anatomical education, offering medical professionals, educators, and patients a clear visual understanding of spinal degeneration progression. Unlike traditional single-stage models that show only one condition at a time, this comprehensive teaching tool presents four distinct pathology stages side by side on a single integrated base.The model displays a complete progression timeline: a healthy lumbar segment demonstrating normal disc structure and vertebral alignment; early stage degeneration showing initial disc desiccation and minor changes; moderate protrusion stage revealing disc bulge with early nerve involvement; and severe herniation stage illustrating advanced disc extrusion and significant nerve compression. This side-by-side comparison enables instant visual differentiation between stages—a critical feature for both education and patient communication.Specifications:Product name: 4-stage sick lumbar vertebra contrast modelProduct material: PVCProduct size: 26.7*15.5*9 cm/10.5*6.1*3.54 inPackage contents:1*model1*English instruction card

• CLEARLY DEMONSTRATE DISEASE PROGRESSION: Transform abstract medical concepts into an instantly understandable visual timeline. Instead of struggling to explain the difference between a healthy disc and advanced herniation with words alone, this 4-stage lumbar spine model presents four distinct pathology stages side by side—healthy, early degeneration, moderate protrusion, and severe herniation
• SIMPLIFY PATIENT EDUCATION IN CLINICAL SETTINGS: Bridge the communication gap between medical professionals and patients during consultations. Whether you're an orthopedist explaining sciatica or a chiropractor discussing nerve compression, this disc model allows you to show exactly where and how pathology develops
• ELEVATE CLASSROOM INSTRUCTION WITH SIDE-BY-SIDE COMPARISON: Move beyond static textbook diagrams that fail to convey pathological progression. This spine pathology model features four stages fixed on a single integrated base, enabling powerful “before and after” teaching moments. Students, nursing trainees, and anatomy learners can compare healthy anatomy against pathological changes in real time
• BUILT FOR FREQUENT HANDLING IN DEMANDING ENVIRONMENTS: Crafted from high-quality, eco-friendly PVC material that resists deformation, tearing, and wear even after years of daily use in classrooms, clinic offices, and lecture halls. The compact design (10.5 x 6.1 x 3.5 inches) with integrated base makes it easy to display on desks or carry between teaching sessions. This education model maintains its structural integrity through repeated handling and frequent demonstrations
• SUPPORT HEALTH AWARENESS CAMPAIGNS ANYWHERE: From community health fairs to corporate wellness events, this patient education spine model fits easily into a bag for portable outreach. Use it to teach prevention strategies, demonstrate the impact of poor posture, or explain why early intervention matters for spinal health. The lightweight, portable design makes it an essential tool for public health education and preventive care initiatives
