Active clinical trials for "Intervertebral Disc Displacement"

Approximately 300,000 patients undergo open surgical procedures to treat symptoms caused by disc herniation. Among the various surgical techniques practiced the percutaneous discectomy occupies its space since the first description of the technique by Hijikata, 1975. Throughout, many techniques have been described. Studies indicate that the treatment was successful for pain and disability resulting from herniated disc associated with radiculopathy small. However, some methods remove very small amounts of tissue with little change in volume of the disc. Thus, studies on the cadaver with Percutaneous Diskectomy by SpineJet ® showed more macroscopic changes of the disc with a predictable amount of removal and significant disc material. The Percutaneous Diskectomy by SpineJet ® is a new technique of percutaneous diskectomy which creates a suction effect in tissues adjacent to the exit point of the fluid and the opening point of the collector. However, no studies have examined the effect of the Percutaneous Diskectomy by SpineJet ® in humans about the disk size after treatment or measures of disc degeneration by imaging methods or how these characteristics might correlate with clinical outcomes. Thus, the study will compare outcomes of patients with contained or extruded disc herniation, with complaints of radiculopathy, concordant with the imaging findings. With treatment by surgical technique or the traditional by SpineJet ®, in order to determine whether percutaneous discectomy with SpineJet ® will produce results comparable to open microdiskectomy.

The purpose of this clinical trial is to assess the safety and effectiveness of the Investigational implant as compared to the Control implant in the treatment of patients with one level or two adjacent levels of cervical symptomatic degenerative disc disease.

The primary objective of the study is to evaluate the safety and efficacy of CEP-37247 compared with placebo as assessed by the occurrence of adverse events, and the mean change in average pain intensity (API) in the affected leg.

The purpose of this study is to find out if use of a cervical disc prosthesis in the treatment of a cervical disc herniation preserves or restores normal mobility and movement in the cervical spine.

The effectiveness of physical therapy for treatment of anterior disc displacement without reduction of temporomandibular disorders has not been well defined. This study compared the treatment method with conservative splint therapy. Fifty two subjects were assigned at random to either of two treatment groups: one is a splint treatment group, and the other is a joint mobilization self exercise group. Each treatment was evaluated using four outcome variables: (i) maximum mouth opening range without and (ii) with pain, (iii) present pain intensity, and (iv) limitation of daily activities. All outcome variables were significantly improved after eight-week of treatment in the exercise group. Meanwhile, the splint treatment improved three variables, other than "mouth opening with pain"; however, the degree of improvement was less than that seen in the exercise group. This result demonstrates that the joint mobilization self exercise improves jaw function and relieves pain as compared to the splint treatment.

The purpose of this study is to compare a standard surgical procedure, open surgical microdiscectomy, used primarily to relieve leg pain and repair disc herniation to a newer surgical procedure, hydrodiscectomy with Spinejet®. The study will examine how well each procedure reduces subject pain and disability over a one-year period. Magnetic resonance imaging (MRI-use of a magnetic field to produce an image) of the lower spinal column taken before and after surgery will also be looked at to determine what physical changes have taken place over the course of a year. Subjects enrolled in this study will also be asked to keep track of their medical expenses related to treating their back pain to see if the surgeries being compared reduce out of pocket expenses.

Hypothesis - This study is designed to evaluate the results of using the Orthotrac Pneumatic Vest versus an EZ form brace in patients with radiating leg pain from disc bulge / protrusion / herniation. Specifically, our hypothesis is that patients given the Orthotrac Pneumatic Vest (OPV) will have greater pain relief and increased self-reported functionality and fewer progressions to surgery than those using the EZ form brace.

This study tests the effectiveness of different treatments for the three most commonly diagnosed lumbar (lower) spine conditions. The purpose of the study is to learn which of two commonly prescribed treatments (surgery and non-surgical therapy) works better for specific types of low back pain. In this part of the study, people with lumbar intervertebral disc herniation (damage to the tissue between the bones of the lower spine, or backbone) will receive either discectomy (surgical removal of herniated disc material) or non-surgical treatment. This study does not cover the cost of treatment.

Low back pain is one of the leading causes of disability, and its social burden and economic cost are quite high. Although there are many causes that can lead to low back pain, radicular pain, which develops mostly secondary to lumbar disc hernias, is one of the most common pathologies. Epidural corticosteroid and local anesthetic injections are an important treatment option in the treatment of lumbar radicular pain that does not respond to conservative methods. For fluoroscopy-guided epidural injections; transforaminal, interlaminar and caudal approaches may be preferred. It is accepted as the superiority of the transforaminal approach that it allows access to the area of pathology, thus to the anterior epidural area where inflammatory mediators are more concentrated, and that it can spread to the target specifically around the inflamed nerve roots. In transforaminal epidural injections, the use of ultrasound as the sole imaging tool throughout the entire procedure is still not appropriate, as subbony structures cannot be visualized. However, ultrasound can be integrated at any stage of the process. Thus, the relatively inexpensive cost, portability, and ability to show non-osseous tissues of ultrasonography are utilized, particularly in terms of reducing radiation exposure. Gofeld et al. claimed that ultrasound-guided transforaminal epidural injection could be performed by targeting the posterior part of the vertebral body. However, in cases where the lamina is wide and covers the posterior of the vertebral body, it may not be possible to sonographically view the vertebral body. In addition, although the intervertebral disc is differentiated from the corpus, loss of fluid content in the elderly can cause acoustic shadowing in the disc. This may result in accidental intra-disc injections. Finally, even if the target point is reached, it is not possible to show intravascular spread at this level ultrasonographically. Therefore, in our opinion, this method is unreliable for transforaminal epidural injections. Another study used ultrasound and fluoroscopy together for transforaminal epidural injections. After imaging the lamina of the relevant vertebral level sonographically, the needle is directed to the lateral edge of the lamina, then fluoroscopic imaging is performed after it passes under the lamina with the loss of resistance technique. However, it should be known that the loss of resistance technique is not a suitable and reliable method in transforaminal injections. In addition, since it is not known how far the lamina has progressed after it has passed under the bone, in other words, imaging guidance is disabled in this part of the process. In our clinic, we use ultrasonography and fluoroscopy methods in an integrated way (hybrid method) for transforaminal epidural injections. For this purpose, we proceed to fluoroscopic imaging immediately after the spinal needle is advanced to the lateral edge of the lamina at the vertebral level where there is pathology with ultrasound. We think that with this method, we continue to stay in the safe window and reduce the radiation dose and procedure time. Based on this, we determined the aim of this study as the effect of including ultrasonography guidance in transforaminal epidural injections on radiation dose and procedure time.

This study will be conducted to compare the effect of sustained natural apophyseal glides (SNAGS) versus neural mobilization on clinical outcomes such as 1- nerve root function in the form of: (A) peak to peak amplitude; (B) latency; (C) F wave. 2- pain pressure threshold (PPT) and 3- Neck disability index (NDI) in patients with cervical disc (C5-C6 and/or C6-C7) herniation. Seventy two patients from both gender with cervical disc (C 5-C 6 and/or C 6- C7) herniation with both sensory and motor nerve affections will be recruited for this study following referral from an experienced neurologist and confirmed diagnosis by MRI. The patients' age will range between 20-50 years, body mass index (BMI) from 18 to 25 kg/cm2. The patients will be assigned randomly by permuted block to three equal groups; group (A) will receive SNAGS in addition to traditional therapy, group (B) will receive neural mobilization in addition to traditional therapy and group (C) will receive traditional therapy. peak to peak amplitude, nerve latency and F wave will be measured by electromyography, , pressure pain threshold will be measured by commander algometer. Neck disability will be measured by Arabic neck disability index.
