The most common neck pain is non-specific mechanical neck pain caused by muscle strain, ligament sprain, spasm, or a combination No specific lesions, or findingsUsually caused by daily activitiesPhilip D. Sloan, Essentials of the family medicine , Chapter 37 Introduction , Wolters Kluwer , 6th edition
PatophysiologyIrritation or inflammation on cervical tissue can produce pain The nociceptive sites on cervical area are:Anterior & Posterior Longitudinal LigamentOuter Annulus Fibrosus DuramaterSpinal Nerve Root Facet Joint Capsule Muscles Caillet R. Neck and Arm Pain, 3rd ed., Philadelphia: F.A.Davis, 1991.
PatophysiologyTwo major mechanisms of neck pain are trauma and arthritisTrauma:External traumaPostural traumaTension traumaArthritis: Degenerative arthritis Sequelae of acute inflammation arthritisCaillet R. Neck and Arm Pain, 3rd ed., Philadelphia: F.A.Davis, 1991.
PatophysiologyExternal Trauma: The neck received external forces that cause abnormal cervical vertebrae position or movement that leading to injury and painCaillet R. Neck and Arm Pain, 3rd ed., Philadelphia: F.A.Davis, 1991.
PatophysiologyPostural Trauma:Wrong posture can cause various trauma to the musculoskeletal system, especially the vertebral column:Forward head postureDropping shoulder

The Scientic Evidence Strongly Supports the Use of: Screening protocols in emergency care in low risk patient with blunt trauma to the neckCT-scanning in emergency care for high-risk patients with blunt trauma to the neckFor non-emergency neck pain:Manual provocation tests in patients with neck pain and suspected radiculopathyThe combination of history, physical examination, modern imaging techniques, and needle EMG to diagnose the cause and site of cervical radiculopathySelf-reported patient assessment to evaluate perceived pain, function, disability, and psychosocial statusNordin M, Carragee EJ, Hogg-Johnson S, Weiner SS, Hurwitz EL, Peloso PM, et al.

INTERVERTEBRAL DISKS
Intervertebral DisksThe chief structural unit between adjacent vertebral bodies 25% of the total length of the spinal columnFunction:To bind vertebrae together & allow motionContributes to the formation of spinal curves (cervical & lumbar)A self-contained fluid elastic system that absorbs shock during vertical loading & permits transient compression
Intervertebral DisksAllowing fluid displacements within its elastic container, distributes pressure equally The compressive force is not concentrated on the edge of the vertebral body toward which the spine bendsPermits movement, equalizes pressure and forces on the column & disperses the forces.

Intervertebral DisksThe cartilaginous plateHyaline cartilage Covers the bony surfaces of the opposed vertebral bodiesAct as semipermeable membraneAnchors the attachment of the annulus fibrosus
The Disk is made up of two parts:Nucleus pulposus Annulus fibrosus
Nucleus pulposus 40% of cross sectionBetween middle & posterior third of the disk 80% waterPascals Law of fluid under pressureThe external forces that applied to any point is transmitted to every unit area of the interior of the containing vessel

*This is the summary The muscle involved *Jangan lebih dari 1 slide**(eg, disk bulging or degeneration, osteophytes, spondylolysis, congenital facet abnormalities) *Jadiin 2 slide*Postural cause of neck pain is frequently found and leading to disabilityNormal cervical postur is defined by cervical lordosis that maintained to keep the head in line with gravity line, where the head is slightly anterior to the gravity line Upper point of gravity line is on the outer ear cavity
*Jadiin 2 slide*in shoulder, arm and hand, with the most frequent site in interscapula area with or without radiation to the occiput, shoulder or arm
*fleksibilitas spina servikal, re-edukasi postur dan penguatanpartisipasi aktif pasien*The lymphatic vessels from thead, face and neck will drain into the superficial & deep cervical lymph nodesAnd then to the right and left jugular lymphatic trunkThe right jugular lymphatic trunk will drain directly into right venous angleBut the left jugular lymphatic trunk will drain into the left venous angle through the thoracic duct
Arahnya kemana Pijatan Otot origo insersio*There are 8 cervical spinal nerves come out from foramen intervertebralis, despite of 7 cervical vertebral columnsThe 1st cervical spinal nerve comes out from above atlas/C1/1st cervical vertebral columnthe 8th cervical spinal nerve comes out from foramen intervertebralis between C7-T1*Motoric component cervical spinal nerves innervate variuous muscle according to the levelSensoric component cervical spinal nerves has segmental area of innervation known as dermatomes*There are two plexus that arise from cervical spinal nerves root*The VAS is best at detecting change in patients who improve in pain. *The NDI, a neck-specic functional status questionnaire, 10 items including pain, personal care, lifting, reading, headaches, concentration, work, driving, sleeping and recreation.the NDI has proofed to be a valid tool for functional assessment of neck disability. & the most commonly used self-report measurefor neck painThe NDI can be used to evaluate the patients status at present and to evaluate the evolution during the therapy**Nukleus pulposus hanya dapat menahan tekanan / beban yang terbatas.
