The most common mechanisms are motor vehicle accidents and falls. The anterior disk space is typically widened, and there may be associated fracture- dislocation of the facet joints and pedicles. Other findings include anterior subluxation with normal interlaminar or interspinous spaces. Cervical spine hyperflexion injuries are the most common injuries to the spine (50-60). They result from varying degrees of forward bending with the posterior third of the intervertebral disc space as the fulcrum. They produce narrowing of the anterior disk space and distraction of the posterior ligament complex and posterior disk space (Fig. Other findings include anterior subluxation with widened interlaminar or interspinous spaces.
Anterolisthesis - grading, symptoms, Treatment, causes
1, findings: lateral view of cervical spine shows forward displacement of C6 over C7 with anterior widening of C6-C7 disc space (a, arrow). Sagittal ct confirms anterior widening of C6-C7 disc space and less than 50 anterior translation. Avulsion fragment arising from the anterior aspect of C7 (B, white arrow) and fracture with comminution of the posterior elements (B, red arrow). The spino-laminar line (yellow arrows) is not altered. Axial ct shows comminution of laminae (c, arrows). The lesion was erroneously diagnosed as a flexion fracture because of the anterolisthesis, without considering the anterior diastasis favourite and absence of diastasis of the posterior elements. Cranial halo traction was applied and the radiograph worsened (Fig. With the use of halo traction, an increase in malalignment with greater C6-C7 displacement is observed (arrows). Halo traction was removed based on the signs suggesting hyperextension injury. The patient underwent surgery shortly afterwards. Final diagnosis: Hyperextension fracture c6-C7 dislocation, lower cervical spine hyperextension injuries are the result of varying degrees of backward bending, with the articular pillar serving as the fulcrum of motion.
This can cause gradual stiffening and muscle aches, as well as nerve problems such as sciatica. Increased disc damage is a universal problem for fast bowlers, which can also lead to a shortened career. These types of back injuries can not only impact on your game, but also affect you for the rest of your life. Bowling is unnatural activity with huge physical demands and, therefore, requires significantly increased strength and flexibility. The importance of having a coach guaranteed look at your action and performing regular, intense core stability work outs cannot be emphasised enough for young fast bowlers, even if performing once a week. Sure health Chiropractic Blog. This week i am presenting a lateral radiograph of the cervical spine in a 45-year-old man with cervical pain and an acute spinal cord lesion after a hang gliding accident. None of the above 45-year-old man, lateral radiograph of cervical spine.
The mechanism of action involves a tendency for vertebra in a hyper-extended spine to slip forward (Anterolisthesis). The vertebral body is being squeezed forward, while the muscles attaching to the posterior aspect of the vertebra try to hold it in place. The end result is a stretching of the weakest parts of the vertebra. This is usually what is meant by a stress fracture, and research published by the south African Medical journal indicates that all high level fast bowlers will have some degree of this kind of injury by the age. Bone is very adaptive tissue, and will grow in response to stresses placed on it, and hence in most cases the stretching of a pars (Spondylolysis) does not cause a fracture as such. However, if left untreated the extent of this stretching of bone can be too great for your body to cope with, resulting in a break in the bone. This is what caused Graham Onions to have an 18 month career hiatus recently. Premature degeneration is also a risk for fast bowlers. The abnormal stress of bowling causes early onset osteoarthritis (Spondylosis) in spinal facet joints.

Surgery in this area is difficult and is suggested only when there is substantial herniation of the army intervertebral disc tissue. Take care, buddy. Hello every body, i thought I'd copy over an article from my website relating to the prevalence of stress fractures amongst fast bowlers. The back injury with duties the worst stigma is stress fracture. The words send a chill through any fast bowler's spine, as a potentially career threatening injury.
Stress fractures happen when you over-extend your low back on a regular basis. They affect part of the vertebra known as the pars interarticularis. You have two pars on each vertebra, and usually a stress fracture will only affect one. It is most common for this to be the same side as the lead leg (left side if a right arm bowler) because of the load transmitted when this leg impacts the ground, as well as a tendency for most fast bowlers to flex slightly. The most common age for stress fractures is between 18 and. This is when cricketers begin taking on the full load of adult cricket, but they are still skeletally immature. Because the spine is one of the last places in the body to finish growing, it is one of the most likely to suffer stress fracture.

However, it is advisable that you visit an orthopedician, preferably in a big hospital or institutional setup, not a solo clinic. Hospitals are adequately equipped to meet emergencies.

He may consider giving you intradiscal injections of corticosteroids. 3 to 4 such injection are usually enough to take care of such inflammations. Muscles relaxants are also given. Serratiopeptidase is a potent anti-inflammatory enzyme helpful in such conditions.
Spinal Stenosis: Practice Essentials, Anatomy, pathophysiology
Iii) Modic type 3 is the stage where all inflammation is finally replaced by bone scarring. Since your summary mri is showing modic type 1 changes, you have active inflammation in your back adjacent to end plates, which is giving you the pain. Management of Backpain in Lumbar Vertebral Area. It wont be proper to rush for surgery. Strong anti-inflammatory medication needs to be tried first. It is something like you have many blisters there. Give yourself adequate rest. Dont strain that part biography in any way. Avoid all movements that give you pain.
Presence of signs of inflammations in the area, that is swelling etc. Later on, fat tissue may get deposited. Inflammation finally leads to bone scarring. Pathologically, these changes are called modic changes and are grouped into 3 types. I) Modic type 1 changes show signs of active inflammation. These signs are pain, presence of minor fractures and other breakages near the endplate area, accumulation of inflammatory fluid biology in the region leading to swelling. This stage is very painful and the pain usually correlates with the amount of inflammation. Ii) Modic type 2 is when the marrow gets substituted by yellow fat.
first know what these modic changes are. These are vertebral endplate and subchondral bone marrow changes due to the degeneration of discs. These are observed on mri as signal intensity changes in vertebral body near the end plates of the affected discs. With increasing age and repeated stress, wear and tear occurs in our back. This includes: wearing out of the cushions provided between two vertebrae. Shortening of the height between two vertebrae. Minor fractures in the bony areas (like trabeculae) of the vertebrae.
Posterior annular disc bulge causing bilateral foraminal stenosis and mild spinal canal stenosis. Vertebral alignment appears normal. No evidence of spondylolisthesis seen. Vertebral bodies, pedicles, laminae, spinous processes and facetal articulation appear normal. Normal marrow signal intensity preserved. Mid sagittal spinal canal measurement. L1-L217 mm L214 mm, l2-L316 mm L314 mm, l3-L415 mm L413. L4-L511 mm L513 mm, l5-S111 mm, sir in this case, i am eagerly waiting your precious suggestions. Kindly inform me if surgery is its only remedy?
Chapter 6: general spinal biomechanics - chiro
Q : dear doctor, since 3 years I have been suffering from backache. On 24th February 2011, i took an mri scan of lumbar spine. Its result is shown below: At L1-L2, L2-L3 and L3-L4 no disc desiccation seen. Discs show no significant bulge/herniation. No evidence of significant primary canal / foraminal stenosis seen. At L4-L5 disc desiccation seen with reduced disc height. Para-discal bone marrow margaret appears hypointense on T1w, hyperintense on T2W images suggestive of modic type i changes. Posterior disc protrusion causing significant spinal canal and bilateral foraminal stenosis with compression of the exiting nerve roots. At L5-S1 no disc desiccation seen.
