A Prospective Study Comparing Platelet-Rich Plasma and Local Anesthetic (LA)/Corticosteroid in Intra-Articular Injection for the Treatment of Lumbar Facet Joint Syndrome

By London Spine

OBJECTIVES: To compare the effectiveness and safety between autologous platelet-rich plasma (PRP) and Local Anesthetic (LA)/corticosteroid in intra-articular injection for the treatment of lumbar facet joint syndrome. METHODS: Forty-six eligible patients with lumbar facet joint syndrome were randomized into group A (intra-articular injection with PRP) and group B (intra-articular injection with LA/corticosteroid). The following contents…

Comparison of Ultrasound-Guided Local Ozone (O2-O3) Injection vs Corticosteroid Injection in the Treatment of Chronic Plantar Fasciitis: A Randomized Clinical Trial

By London Spine

Objective: Plantar fasciitis (PF) is one of the most common causes of heel pain. The affected area is often close to the attachment of plantar fascia to calcaneus bone. The purpose of this study was to compare the effects of ozone (O2-O3) injection to corticosteroid injection under ultrasound guidance for the treatment of chronic PF. Design: Randomized clinical trial. Setting: Academic University and Neuromusculoskeletal Research Center. Subjects: Thirty patients with chronic PF. Methods: The patients were randomly divided into two groups receiving methylprednisolone (15 subjects) vs ozone (O2-O3; 15 subjects). The following outcome measures were assessed before injection and then two weeks and 12 weeks after the injection in each group; morning and daily pain via visual analog scale, daily life and exercise activities via the Foot and Ankle Ability Measure, and plantar fascia thickness at insertion and 1 cm distal to its insertion into the calcaneus via ultrasound imaging. Results: Intragroup changes showed significant improvement in pain, functional parameters, and sonographic findings in both groups (P < 0.05). Pain reduction (both daily and morning) and daily activity improvement were better in the corticosteroid group two weeks after injection; however, at 12 weeks, the ozone (O2-O3) group had significantly more improvement (P = 0.003, P = 0.001, and P = 0.017, respectively). Conclusions: Both methods were effective in the treatment of chronic PF. Steroid injection provided a more rapid and short-term therapeutic effect. However, ozone (O2-O3) injection led to a slow and longer-lasting treatment outcome. Ozone (O2-O3) injection can be an effective treatment, with slow onset and a longer durability in the treatment of chronic PF

Abstract
PURPOSE: The purpose of this study is to compare bone union rate between autologous iliac bone and local bone graft in patients treated by posterior lumbar interbody fusion (PLIF) using carbon cage for single level interbody fusion. METHODS: The subjects were 106 patients whose course could be observed for at least 2 years. The diagnosis was lumbar spinal canal stenosis in 46 patients, herniated lumbar disk in 12 patients and degenerative spondylolisthesis in 51 patients. Single interbody PLIF was done using iliac bone graft in 53 patients and local bone graft in 56 patients. Existence of pseudo-arthrosis on X-P (AP and lateral view) was investigated during the same follow up period. RESULTS: No significant differences were found in operation time and blood loss. Significant differences were also not observed in fusion grade at any follow up period or in fusion progression between the two groups. Donor site pain continued for more than 3 months in five cases (9 %). The final fusion rate was 96.3 versus 98.3 %. CONCLUSIONS: Almost the same results in fusion were obtained from both the local bone group and the autologous iliac bone group. Fusion progression was almost the same. Complications at donor sites were seen in 19 % of the cases. From the above results, it was concluded that local bone graft is as beneficial as autologous iliac bone graft for PLIF at a single level.

Subdural spread of injected local anesthetic in a selective transforaminal cervical nerve root block: a case report.

Abstract
INTRODUCTION: Although uncommon, selective cervical nerve root blocks can have serious complications. The most serious complications that have been reported include cerebral infarction, spinal cord infarction, transient quadriplegia and death.
CASE PRESENTATION: A 40-year-old Japanese woman with a history of severe right-sided cervical radicular pain was scheduled to undergo a right-sided C6 selective cervical nerve root block using a transforaminal approach under fluoroscopic guidance. An anterior oblique view of the C5-C6 intervertebral foramen was obtained, and a 23-gauge spinal needle, connected to the normal extension tube with a syringe filled with contrast medium, was introduced into the posterior-caudal aspect of the C5-C6 intervertebral foramen on the right side. In the anteroposterior view, the placement of the needle was considered satisfactory when it was placed no more medial than halfway across the width of the articular pillar. Although the spread of the contrast medium along the C6 nerve root was observed with right-sided C6 radiculography, the subdural flow of the contrast medium was not observed with real-time fluoroscopy. The extension tube used for the radiculography was removed from the spinal needle and a normal extension tube with a syringe filled with lidocaine connected in its place. We performed a negative aspiration test and then injected 1.5 mL of 1.0% lidocaine slowly around the C6 nerve root. Immediately after the injection of the local anesthetic, our patient developed acute flaccid paralysis, complained of breathing difficulties and became unresponsive; her respiratory pattern was uncoordinated. After 20 minutes, she regained consciousness and became alert, and her muscle strength in all four limbs returned to normal without any sensory deficits after receiving emergent cardiorespiratory support.
CONCLUSIONS: We believe that confirming maintenance of the appropriate needle position in the anteroposterior view by injecting local anesthetic is important for preventing central needle movement. Because the potential risk of serious complications cannot be completely eliminated during the use of any established selective cervical nerve root block procedure, preparation for an emergency airway, ventilation and cardiovascular support is indispensable in cases of high spinal cord anesthesia.
