تشريح العمود الفقري العنقي والأقراص الفقرية

لفهم مرض القرص التنكسي العنقي، من الضروري أولاً التعرف على التركيب المعقد للعمود الفقري العنقي (الرقبة) والأقراص الفقرية التي تلعب دورًا حيويًا في حركته ووظيفته.

تركيب العمود الفقري العنقي

يتكون العمود الفقري العنقي من سبع فقرات، يُرمز إليها بالحروف C1 إلى C7. هذه الفقرات هي الأصغر والأكثر مرونة في العمود الفقري، وتسمح للرأس بالتحرك في جميع الاتجاهات. بين كل فقرة وأخرى (باستثناء الفقرتين C1 و C2) يوجد قرص فقري.

وظيفة الأقراص الفقرية العنقية

توجد ستة أقراص فقرية هلامية الشكل في الرقبة، تعمل كوسائد لامتصاص الصدمات ومنع احتكاك عظام الفقرات ببعضها البعض أثناء حركة الرقبة. هذه الأقراص ضرورية لتوفير المرونة والدعم للعمود الفقري.

يتكون كل قرص فقري من جزأين رئيسيين:

• الحلقة الليفية (Annulus Fibrosus): وهي الطبقة الخارجية القوية والمرنة، تتكون من شبكة من الألياف الغضروفية المتشابكة التي تحيط بالمركز.
• النواة اللبية (Nucleus Pulposus): وهي المادة الداخلية اللينة الشبيهة بالهلام، الغنية بالبروتينات المخاطية، والتي تمنح القرص خاصية امتصاص الصدمات.

في الأطفال، تحتوي الأقراص على حوالي 85% من الماء، مما يمنحها مرونتها وقدرتها على امتصاص الصدمات. ومع التقدم في العمر، تبدأ الأقراص في فقدان ترطيبها بشكل طبيعي. تشير بعض التقديرات إلى أن محتوى الماء في القرص قد ينخفض إلى حوالي 70% بحلول سن السبعين، ولكن في بعض الأشخاص، قد تفقد الأقراص ترطيبها بسرعة أكبر بكثير.

كيف تتدهور الأقراص العنقية

عندما يفقد القرص ترطيبه، يصبح عرضة للتشقق والتمزق.

مع فقدان القرص لترطيبه، تقل قدرته على امتصاص الصدمات ويصبح أكثر عرضة للتشققات والتمزقات. الجدير بالذكر أن القرص لا يستطيع إصلاح نفسه بشكل كامل لأنه لا يمتلك إمدادًا دمويًا مباشرًا. بدلاً من ذلك، يحصل على العناصر الغذائية والمستقلبات عبر الانتشار من الفقرات المجاورة من خلال الصفائح الغضروفية النهائية. وبالتالي، فإن أي تمزق في القرص إما لن يلتئم أو سيتطور إلى نسيج ندبي أضعف لديه القدرة على التمزق مرة أخرى.

الأسباب وعوامل الخطر لمرض القرص التنكسي العنقي

على الرغم من أن مرض القرص التنكسي العنقي هو جزء طبيعي من عملية الشيخوخة التي يمر بها الجميع تقريبًا، إلا أن هناك عدة عوامل يمكن أن تسرع من تطوره أو تزيد من احتمالية ظهور الأعراض المؤلمة في سن مبكرة.

الأسباب الرئيسية للتدهور

• التقدم في العمر (التآكل والتمزق): هذا هو السبب الأكثر شيوعًا. مع مرور الوقت والاستخدام المتكرر للرقبة، تتعرض الأقراص لضغط مستمر، مما يؤدي إلى فقدانها للماء والمرونة تدريجيًا.
• المكون الوراثي: تشير بعض الدراسات إلى وجود استعداد وراثي لدى بعض الأشخاص لتآكل الأقراص بشكل أسرع. إذا كان هناك تاريخ عائلي للحالة، فقد يزيد ذلك من خطر الإصابة بها.
• الإصابات: قد تؤدي الإصابات المباشرة للرقبة، مثل حوادث السيارات أو السقوط، إلى تسريع أو حتى التسبب في تطور التغيرات التنكسية في الأقراص. على سبيل المثال، يمكن أن يؤدي الانزلاق الغضروفي العنقي إلى بدء أو تسريع عملية التدهور.

عوامل الخطر التي تزيد من احتمالية الإصابة

هناك عدة عوامل نمط حياة وصحية يمكن أن تزيد من خطر تطور مرض القرص التنكسي العنقي أو تفاقم أعراضه:
