Anterolisthesis of C3 on C4 (is it the same as Anterior Subluxation?
Intraforaminal - most common / often dermatomal distribution 2. Spondylosis / Disc degeneration - loss of height / annular bulging - foraminal compression 3. Bony A. Uncovertebral osteophytes / hard discs - compress nerve root anteriorly B. Superior articular facet osteophyte - extend from ventral surface to compress the neural foramen - are less common Pain / parasthesia - often don’t follow dermatomal distribution Weakness - 60-70% motor deficiency Spurling maneuver - hyperextension with tilt toward affected side - stimulates radiculopathy symptoms Nerve root signs (C6 and C7 most common) C2 Posterior occipital headaches C3 Occipital headache C4 Neck and trapezial pain +/- shoulder / scapula pain C5 Pain lateral upper arm (epaulet) / deltoid weakness / biceps jerk decreased C6 Radial forearm and hand pain / weak biceps and wrist extension / BR reflex decreased C7 MF pain / weak triceps / absent triceps jerk C8 Pain ring and little fingers / weak finger flexors T1 Ulna forearm pain / weak hand intrinsics Entrapment syndromes (ulna / median nerves) Thoracic outlet syndrome RC disease Demonstrate loss of disc height and degeneration Note - 19% of asymptomatic patients will have evidence of nerve root compression - difficult to distinguish between hard and soft discs Adds complementary information to MRI in C spine Demonstrates the posterolateral impingement is from “hard” disc - i.e.
Approximately 2 mm anterolisthesis of C3 on C4 with flexion only
C4-C5: The Please Help with my Spinal MRI Results - Spinal Cord Disorders Dec 11, 2012 Grade 1 anterolisthesis is seen at C4/5 and at C7/T1.
Anterolisthesis of c4 - Tombstone Hearse & Trike
I am 21 and grade 1 retrolisthesis of C3 on C4 is being noticed in my Spondylolisthesis Overview | Grades, Causes, and Treatments This in-depth discussion about spondylolisthesis explains what causes a vertebra to slip and what the different grades (eg, grade 1 spondylolisthesis) look like.
How can the answer be improved?
Anterolisthesis and retrolisthesis of the cervical spine in cervical spondylotic myelopathy in the Anterolisthesis – Symptoms, Causes and Treatment - Hx Benefit In grade 2 anterolisthesis, the slippage is more than 25% but less than 50%.The mean difference between the static and dynamic canal diameters was statistically significant at C3-4 (p How to cite this URL: Vyas K H, Banerji D, Behari S, Jain S, Jain V K, Chhabra D K.

Sublaminar wiring - Gallie / Brooks 2. Transarticular / Magerl screws 3. Harms technique - C1 lateral mas screws - C2 pedicle screws Indication - C1/2 instability - peg fracture with anterior displacement - rupture of transverse ligament Advantages - relatively easy technique - graft firmly fixed between two arches of C1 and C2 - aids in reduction of the anterior subluxation Disadvantages - sublaminal wiring technique - can't use with C1 arch fracture - not suitable for posterior peg displacement Technique Prone position - head in line traction with tongs - midline incision occiput to C4 - soft tissue dissection from midline - no further than 1.5cm from midline to avoid vertebral artery and venous plexus - clear soft tissues of posterior arch C1 circumferentially to allow passage of wire - 1.2mm wire is fashioned as loop with a hook - loop is passed deep to C1 arch from inferior to superior - then passed over arch superficially so loop ends up around C2 spinous process - unless C1 and 2 are reduced significant risk of injury to cord at this point - decorticate arch of C1 and C2 - corticocancellous rectangular graft 3x4cm removed from post iliac crest - fashioned into a "H" to fit snugly around SP's - fashion cancellous surface to fit snugly on post arches - notch graft laterally to fit wire - tie wire over graft to secure in place - pack with cancellous graft around op site Post-op - HTB for 3/12 Indications - C1/2 fusion with sublaminar wiring - biomechanically superior to Gallie technique - more rotational control - able to use with posterior displacement of peg Technique - clear C1 and C2 post arches circumferentially - 2 lateral wire loops around each lamina - 1.5 x 3.5cm wedged corticocancellous grafts between lamina C1 and C2 both sides Indications - C1/2 fusion - acute and chronic atlanto-axial instability - suitable for posterior arch fracture and posterior dislocation Disadvantage - technically difficult Preop CT - determine sufficient bone for 3.5 mm screw / sagittal reconstructions - exclude overriding vertebral artery / axial view Technique - patient prone - ensure reduction with II - flex neck - approach midline occiput to C7 - expose posterior elements C1-C3 as above - persistent anterior dislocation may be reduced by pushing on C2 SP or pulling on C1 - expose C2 lamina not out to vertebral artery - under lateral image control pass 2.5mm drill C2 to C1 - entry at lower edge of caudal articular process C2 - 3mm from inferior surface and 2mm lateral to medial edge - drill passing through posteromedial surface of lateral mass atlas – 25o cranially, under II - drill to anterior cortex and place appropriate 3.5mm cortical screw - following screw fixation posterior fusion performed Post-op - Collar 6-10 weeks Indication Technique - C1 lateral mass screws - C2 lateral mass screws Advantage - maintain motion - less blood loss Disadvantage - technically difficult - 17% major complication rate Contra-indications - obesity - short fat necks - irreducible fracture - reverse obliquity - comminution - delayed or nonunion / unable to debride or bone graft Technique Approach - anterior approach at level C5/6 - this allows correct angle for wire insertion - split platysma, open deep fascia - SCM and carotid sheath laterally - blunt dissect to prevertebral fascia medially - split prevertebral fascia / between longus colli - palpate inferior aspect of C2 Reduction - anterior displacement easy: extend neck - posterior displacement more difficult: traction and bring head forward Cannulated wire insertion - need good AP and lateral x-rays - wire inserted at C5/6 disc - need sufficient anterior bone in C2 to prevent cut out - 2 wires inserted for rotation control - 1 single 3.5 mm cortical screw just penetrating tip for extra fixation Many techniques - interspinous wiring simplest - TBW of posterior elements - Sublaminar wires here have high neurology rate Technique Midline posterior approach - essential to identify correct level with II - hole drilled in each side of spinous process of upper vertebrae of injured segment - junction upper and middle 1/3's - connect holes with towel clip - 1.2mm wire is passed through hole and around inferior spinous process leaving interspinous soft tissue intact - wires pulled tight then passed around inferior spinous process and tied superiorly - lamina are decorticated and cancellous graft applied Concept - through spinous process - about bone graft each side Technique First wire through transverse hole base SP - two rectangular graft blocks each side - second wire through superior SP & each end into superior holes blocks - third wire through lower SP & bottom block holes - tie ends second and third wires together - decorticate post laminae Lateral mass screws - poly axial heads Preoperative CT - location and orientation of foramen and vertebral artery Entry point - middle of lateral mass / 1 mm medial to centre - aim 10 - 15o lateral - parallel to superior articular facet
