Ligamentum flavum in the cervical region is thin or not fused at the midline. The investigators inferred that the size and elasticity of the ligamentum flavum, in combination with mildline appraoch, the gaps could be responsible for a failure to recognize a LOR in some patients. If so, the investigators hypothesized that the paramedian approach would be advantageous for finding cervical epidural space more easily during cervical epidural steroid injections CESIs. Detailed Description:.
The distinct elastic resistance offered by the ligamentum flavum before entering the epidural space when using the loss of resistance LOR technique may be blunted or even absent. Therefore, the investigators randomly divide our patients into 2 groups; the midline approach group and the paramedian group.
Then, the investigators examine the patterns of the pressure changes at the moment of a puncture of the ligamentum flavum during CESIs. Arms and Interventions. Outcome Measures. Primary Outcome Measures : precipitous decrease [ Time Frame: It will be measured at the moment of puncture of ligamentum flavum during interventional procedure, then participants will be followed for the duration of hospital stay, an expected average of 1 hour.
Secondary Outcome Measures : popping sensation [ Time Frame: It will be measured at the moment of puncture of ligamentum flavum during interventional procedure, then participants will be followed for the duration of hospital stay, an expected average of 1 hour. The bevel of the needle is considered to have entered the epidural space when a typical waveform is observed, which consists of small cardiac oscillations superimposed on greater respiratory oscillations.

These images are used to emphasize the location of the spinal cord. The needle should not be advanced too far ventrally. We recommend observing the safety considerations demonstrated in other views lateral and contralateral oblique. There are no consistent radiolucent safety considerations in this trajectory view. Notes on Positioning in the Trajectory View. Initial needle placement should be shallow in the soft tissues to avoid puncturing the dura and contacting the spinal cord. Needle depth can then be confirmed by rotating into the lateral or contralateral oblique safety view.
Confirm the level with the anteroposterior [AP] view. Tilt the fluoroscope. Maximize the radiolucent size of the targeted interlaminar space usually C7-T1 with the use of a caudad tilt. Oblique slightly to symptomatic side about 5 to 10 degrees. The needle is placed directly midline or just ipsilateral to midline on the painful side in the target radiolucent interlaminar space. Place the needle parallel to the fluoroscopic beam. The needle must remain close to midline this should be confirmed with the AP view to reduce the risk of a false or no LOR if the ligamentum flavum has not fully fused.
In addition, when the needle tip is not midline, it will need to be advanced more ventrally and laterally as a result of the tubular shape of the dura, and it may not have as distinct of a LOR. The tip may be placed slightly off midline ipsilaterally for the treatment of more unilateral symptoms. To safely advance the needle, the C-arm should now be positioned in the lateral safety or contralateral oblique safety view.

Possible prognostic factors for the outcome, such as age, gender, duration of radiculopathy, and cause of radiculopathy were also analyzed. Results: Cervical interlaminar epidural steroid injections were effective in of patients Patients with disc herniation had significantly better results than patients with neural foraminal stenosis Conclusion: There is no significant difference in treatment efficacy between the midline and paramedian approaches in CIESI, for unilateral radiculopathy.
The cause of the radiculopathy is significantly associated with the treatment efficacy; patients with disc herniation experience better pain relief than those with neural foraminal stenosis. Keywords: Cervical spine; Epidural steroid injection; Intervertebral disc; Radiculopathy; Spinal stenosis.
This situation may further be aggravated by the existence of an anterior disc protrusion displacing the spinal cord posteriorly. Consequently the injectionist experiences what amounts to a perceptual "absence" of epidural space and hence, the expected telltale "loss of resistance" sensation, indicating penetration into the epidural space, is not encountered. Under normal circumstances, aspiration of CSF is the primary indication of sub-dural tap, and the procedure can be discontinued immediately, as per guideline 11, with no negative sequelae.
However, due the atypical circumstance that finds the ligamentum flavum, the dural sleeve and the spinal cord pressed closely together, CSF may not be aspirated. Accordingly, believing the epidural space is yet to be encountered, the injectionist may initiate further advancement of the epidural needle, resulting in inadvertent spinal cord puncture. Needless to say, this represents a highly undesirable procedural outcome. Although 5 ml of solution injected at the C7-T1 interspace will often fill the entire space to the C2 level, if the structural pathology is at the C interspace or higher, one can perform a C7-T1 or a T1-T2 puncture and advance a catheter to the desired level.
Rationale: As with guideline 4, this guideline is also apt to generate a polemic, and adherence to it will not it itself guarantee needle misplacement. However correctly utilized, fluoroscopic imaging is an invaluable tool for aiding in the prevention of inadvertent dural or cord punctures. The patient is placed in a prone position with the interspace visualized and pinpointed in the AP projection. Using a paramedian approach, with the epidural needle approximately 1cm from the midline and approximately 2 cm below the border of the lamina, i.
Since the advancing needle is always over bone, unintentional advancement into the spinal canal is prevented. Once the needle contacts the lamina it is advanced cephlad and toward the midline until the resistance of the ligamentum flavum is felt. If the ligamentum flavum is not felt within 5mm then the needle is withdrawn again to the lamina to reestablish correct positioning and recheck depth.

In addition, the cervical ligamentum is significantly associated with the the needle in position at the C7-T1 interlaminar space with 5 to 10 degrees of at the lower levels. We recommend observing the safety by advancing the needle through the ligamentum flavum using the unilateral symptoms. The C7-T1 level is typically advanced too far ventrally in.
