Abstract
BACKGROUND Thoracic facet joint disorder is a common thoracic disorder in clinic, inducing pain and discomfort at the dislocated thoracic vertebrae, radiating to pain of the neck and back. The incidence of thoracic facet joint disorder is higher than the facet disorder of the cervical and lumbar vertebrae. Therefore, an ideal strategy to relieve thoracic facet joint disorder is urgently needed. In recent years, massage therapy has been increasingly accepted by thoracic facet joint disorder patients due to its lower costs, fewer unwanted side effects and safety for clinical use. In this systematic review, we aim to evaluate the effectiveness and safety of massage therapy for patients with thoracic facet joint disorder. METHODS We will search the following electronic databases for randomized controlled trials to evaluate the effectiveness of massage therapy in treating thoracic facet joint disorder: Wanfang and PubMed Database, CNKI, CENTRAL, CINAHL and EMBASE. Each database will be searched from inception to October 2020. The entire process will include study selection, data extraction, risk of bias assessment and meta-analyses. RESULTS This proposed study will evaluate the effectiveness of massage therapy for patients with thoracic facet joint disorder. CONCLUSIONS This proposed systematic review will evaluate the existing evidence on the effectiveness and safety of massage therapy for patients with thoracic facet joint disorder. DISSEMINATION AND ETHICS The results of this review will be disseminated through peer-reviewed publication. Because all of the data used in this systematic review and meta-analysis has been published, this review does not require ethical approval. Furthermore, all data will be analyzed anonymously during the review process. OSF REGISTRATION NUMBER DOI 10.17605/OSF.IO/XMEJD.

Morphometric analysis of the patterns of calcaneal facets for the talus in Serbian population. PLoS One 2020; 15:e0240818. [PMID: 33119596 PMCID: PMC7595338 DOI: 10.1371/journal.pone.0240818] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2019] [Accepted: 10/05/2020] [Indexed: 11/25/2022] Open
Abstract
Literature describes different patterns of calcaneal facets for the talus in terms of whether some calcaneal facets are connected or separated from each other or completely absent. The aim of this study was to establish the patterns of calcaneal facets for the talus, to calculate their total area, and to analyse the data with respect to gender. The study involved 59 calcanei which were photographed. The patterns of calcaneal facets noted in this study were compared with the patterns from the literature. ImageJ program was used to measure different parameters on calcanei. The pattern 1 was the most commonly found in the study sample (45.76%), then the pattern 2 (40.68%), and finally the pattern 3 (13.56%). That order of frequencies is the same in both sexes. The patterns 1 and 2 have a larger contact surface for the talus in comparison to the pattern 3. Male bones have a larger contact surface for the talus than female bones. The sum of the pattern 1 and pattern 3 frequencies was high. Knowing the frequency of different patterns of calcaneal facets for the talus in a certain population is important for orthopaedic surgeons when performing foot osteotomy.

Medial Branch Blocks for Diagnosis of Facet Joint Pain Etiology and Use in Chronic Pain Litigation. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17217932. [PMID: 33137975 PMCID: PMC7662497 DOI: 10.3390/ijerph17217932] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/23/2020] [Revised: 10/22/2020] [Accepted: 10/26/2020] [Indexed: 11/16/2022]
Abstract
A commonly disputed medicolegal issue is the documentation of the location, degree, and anatomical source of an injured plaintiff’s ongoing pain, particularly when the painful region is in or near the spine, and when the symptoms have arisen as result of a relatively low speed traffic crash. The purpose of our paper is to provide health and legal practitioners with strategies to identify the source of cervical pain and to aid triers of fact (decision makers) in reaching better informed conclusions. We review the medical evidence for the applications and reliability of cervical medial branch nerve blocks as an indication of painful spinal facets. We also present legal precedents for the legal admissibility of the results of such diagnostic testing as evidence of chronic spine pain after a traffic crash. Part of the reason for the dispute is the subjective nature of pain, and the fact that medical documentation of pain complaints relies primarily on the history given by the patient. A condition that can be documented objectively is chronic cervical spine facet joint pain, as demonstrated by medial branch block (injection). The diagnostic accuracy of medial branch blocks has been extensively described in the scientific medical literature, and evidence of facet blocks to objectively document chronic post-traumatic neck pain has been accepted as scientifically reliable in courts and tribunals in the USA, Canada and the United Kingdom. We conclude that there is convincing scientific medical evidence that the results of cervical facet blocks provide reliable objective evidence of chronic post-traumatic spine pain, suitable for presentation to an adjudicative decision maker.

Magnetic Resonance Imaging Investigation of Cervical-Spine Meniscoid Composition: A Validation Study. J Manipulative Physiol Ther 2020; 43:579-587. [PMID: 32861523 DOI: 10.1016/j.jmpt.2019.10.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2019] [Revised: 07/30/2019] [Accepted: 10/10/2019] [Indexed: 11/18/2022]
Abstract
OBJECTIVE The composition of cervical-spine meniscoids may have clinical significance in neck-pain conditions, but the accuracy of assessment of meniscoid composition in vivo using magnetic resonance imaging has not been established. The aim of this study was to compare cervical-spine meniscoid composition by magnetic resonance imaging with histologic composition. METHODS Four embalmed cadaveric cervical spines (mean [standard deviation] age, 79.5 [3.7] years; 1 female, 3 male) underwent magnetic resonance imaging, allowing radiologic classification of lateral atlantoaxial- and zygapophyseal-joint (C2-3 to C6-7) meniscoids as either mostly fatty, mixed tissue, or mostly connective tissue. Subsequently, each joint was dissected and disarticulated to allow excision of meniscoids for histologic processing. Each meniscoid was sectioned sagittally, stained with hematoxylin and eosin, examined using light microscopy, and classified as adipose, fibroadipose, or fibrous in composition. Data were analyzed using the kappa statistic with linear weighting. RESULTS From dissection, 62 meniscoids were identified, excised, and processed; 46 of these 62 were visualized with magnetic resonance imaging. For single-rater identifying structures, agreement between assessment of meniscoid composition by magnetic resonance imaging and by microscopy was fair (κ = 0.24; 95% confidence interval, 0.02-0.46; P = .02). CONCLUSION Findings suggest that the accuracy of this method of magnetic resonance imaging assessment of cervical-spine meniscoid composition may be limited. This should be considered when planning or interpreting research investigating meniscoid composition using magnetic resonance imaging.

Facet Tropism and Orientation: Risk Factors for Degenerative Lumbar Spinal Stenosis. BIOMED RESEARCH INTERNATIONAL 2020; 2020:2453503. [PMID: 32685454 PMCID: PMC7341411 DOI: 10.1155/2020/2453503] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/02/2020] [Accepted: 06/17/2020] [Indexed: 11/17/2022]
Abstract
The aim of this study is to establish whether facet tropism (FT) and orientation (FO) are associated with degenerative lumbar spinal stenosis (DLSS). A retrospective computerized tomography (CT) study including 274 individuals was divided into two groups: control (82 males and 81 females) and stenosis (59 males and 52 females). All participants have undergone high-resolution CT scan of the lumbar spine in the same position. FT and FO were measured at L1-2 to L5-S1. Significant sagittal FO was noted in the stenosis males (L2-3 to L4-5) and females (L2-3 to L5-S1) compared to the controls. The prevalence of FT was remarkably greater in the stenosis males (L4-5, L5-S1) and females (L3-4, L5-S1) compared to their counterparts in the control group. Our results also showed that FT (L3-4 to L5-S1) increases approximately 2.9 times the likelihood for DLSS development. This study indicates that FO and FT in the lower lumbar spine are significantly associated with DLSS.

Abstract
BACKGROUND To investigate the biomechanical changes in the development of scoliosis due to intervertebral disc and facet joint degeneration. METHODS We enrolled 39 cases of fresh-frozen lumbar spine specimens and underwent CT scanning and 3D reconstruction. An Osirix Dicom imaging system was to assess the degeneration of the intervertebral disc and facet joints, and mechanical loading was conducted using a spine mechanical instrument with the frequency set at plus/minus 7.5 NM, 0.005 Hz. Range of motion (ROM) and neutral zone (NZ) of 39 cadaveric lumbar spines were tested. FINDINGS Degeneration existed in all 39 cases of the lumbar specimens: the Cobb angle >10° in 5 cases (degenerative scoliosis (DS) group), between 3° and 10° in 9 cases (pre-degenerative scoliosis (PS) group) and <3° in 25 cases (no scoliosis (NS) group). The axial torsion (AT) range of motion (ROMAT) and the NZ of the DS and PS groups was greater than in the NS group and increased with increasing Cobb angle. A significant correlation was found between the degeneration of the intervertebral disc and the AT and the AT correlated with the Cobb angle and facet joint degeneration. INTERPRETATION The AT correlated with intervertebral disc and facet joint degeneration, which might be a mechanic factor in the occurrence and development of degenerative scoliosis.

Finite element analysis of a ball-and-socket artificial disc design to suppress excessive loading on facet joints: A comparative study with ProDisc. INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN BIOMEDICAL ENGINEERING 2019; 35:e3214.

Abstract
Facet arthrosis at surgical level was identified as major complication after total disc replacement (TDR). One of the reasons for facet arthrosis after TDR has been speculated to be the hypermobility of artificial discs. Accordingly, the artificial disc that can constrain the hypermobility of ball-and-socket type artificial discs and reduce loading on facet joints is demanded. The proposed artificial disc, which is named as NewPro, was constructed based on the FDA-approved ProDisc but contained an interlocking system consisting of additional bars and grooves to control the range of motion (ROM) of lumbar spine in all anatomical planes. The three-dimensional finite element model of L1 to L5 was developed first, and the biomechanical effects were compared between ProDisc and NewPro. The ROM and facet contact force of NewPro were significantly decreased by 42.7% and 14% in bending and by 45.6% and 34.4% in torsion, respectively, compared with the values of ProDisc, thanks to the interlocking system. In addition, the ROM and facet contact force could be selectively constrained by modifying the location of the bars. The proposed artificial disc with the interlocking system was able to constrain the intersegmental rotation effectively and reduce excessive loading on facet joints, although wear and strength tests would be needed prior to clinical applications.

Physiologic facet capsule stretch can induce pain & upregulate matrix metalloproteinase-3 in the dorsal root ganglia when preceded by a physiological mechanical or nonpainful chemical exposure. Clin Biomech (Bristol, Avon) 2019; 64:122-130. [PMID: 29523370 PMCID: PMC6067996 DOI: 10.1016/j.clinbiomech.2018.01.009] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/12/2017] [Revised: 12/22/2017] [Accepted: 01/15/2018] [Indexed: 02/07/2023]
Abstract
BACKGROUND Neck pain from cervical facet loading is common and induces inflammation and upregulation of nerve growth factor (NGF) that can sensitize the joint afferents. Yet, the mechanisms by which these occur and whether afferents can be pre-conditioned by certain nonpainful stimuli are unknown. This study tested the hypothesis that a nonpainful mechanical or chemical insult predisposes a facet joint to generate pain after a later exposure to typically nonpainful distraction. METHODS Rats were exposed to either a nonpainful distraction or an intra-articular subthreshold dose of NGF followed by a nonpainful distraction two days later. Mechanical hyperalgesia was measured daily and C6 dorsal root ganglia (DRG) tissue was assayed for NGF and matrix metalloproteinase-3 (MMP-3) expression on day 7. FINDINGS The second distraction increased joint displacement and strains compared to its first application (p = 0.0011). None of the initial exposures altered behavioral sensitivity in either of the groups being pre-conditioned or in controls; but, sensitivity was established in both groups receiving a second distraction within one day that lasted until day 7 (p < 0.024). NGF expression in the DRG was increased in both groups undergoing a pre-conditioning exposure (p < 0.0232). Similar findings were observed for MMP-3 expression, with a pre-conditioning exposure increasing levels after an otherwise nonpainful facet distraction. INTERPRETATION These findings suggest that nonpainful insults to the facet joint, when combined, can generate painful outcomes, possibly mediated by upregulation of MMP-3 and mature NGF.

Abstract
Treatment of back pain due to facet joint syndrome has been a challenge for physicians since its recognition ∼80 years ago. Intra-articular injections of steroids, local anesthetics, and phenol have been widely adopted despite their known shortcomings. Recently, intra-articular injection of amniotic membrane-umbilical cord (AMUC) has been utilized in various orthopedic indications, including those involving synovial joints, due to its reported anti-inflammatory properties. Herein, use of AMUC for facet joint syndrome was evaluated.A single-center case series was conducted on patients presenting with pain caused by facet joint syndrome, confirmed by single blocking anesthetic injection and treated using a single intra-articular injection of 50 mg particulate AMUC (CLARIX FLO) suspended in preservative-free saline. Patient reported back pain severity (numerical scale 0-10) and opioid use were compared between baseline and 6 months following treatment.A total of 9 patients (7 males, 2 females), average age 52.1 ± 15.9 years, were included. Five patients with cervical pain had a history of trauma, 1 patient had suffered lumbar facet injury and 3 had degenerative lumbar facet osteoarthritis. All patients had severe pain prior to injection (8.2 ± 0.8) and 4 (44%) were taking opioids (>100 morphine milligram equivalents). Six-month post-treatment, average pain had decreased to 0.4 ± 0.7 (P <.05). All patients had ceased use of prescription pain medications, including opioids. No adverse events, repeat procedures, or complications were reported.Intra-articular injection of AMUC appears to be promising for managing facet pain and mitigating opioid use. Further investigation with larger sample size is warranted.

Multiscale mechanics of the cervical facet capsular ligament, with particular emphasis on anomalous fiber realignment prior to tissue failure. Biomech Model Mechanobiol 2018; 17:133-145.

Abstract
The facet capsular ligaments encapsulate the bilateral spinal facet joints and are common sources of painful injury due to afferent innervation. These ligaments exhibit architectural complexity, which is suspected to contribute to the experimentally observed lack of co-localization between macroscopic strain and microstructural tissue damage. The heterogeneous and multiscale nature of this ligament, combined with challenges in experimentally measuring its microscale mechanics, hinders the ability to understand sensory mechanisms under normal or injurious loading. Therefore, image-based, subject-specific, multiscale finite-element models were constructed to predict the mechanical responses of the human cervical facet capsular ligament under uniaxial tensile stretch. The models precisely simulated the force-displacement responses for all samples ([Formula: see text]) and showed promise in predicting the magnitude and location of peak regional strains at two different displacements. Yet, there was a loss of agreement between the model and experiment in terms of fiber organization at large tissue stretch, possibly due to a lack of accounting for tissue failure. The mean fiber stretch ratio predicted by the models was found to be significantly higher in regions that exhibited anomalous fiber realignment experimentally than in regions with normal realignment ([Formula: see text]). The development of microstructural abnormalities was associated with the predicted fiber-level stretch ([Formula: see text]), but not with the elemental maximum principal stress or maximum principal strain by logistic regression. The multiscale models elucidate a potential mechanical basis for predicting injury-prone tissue domains and for defining the relationships between macroscopic ligament stretch and microscale pathophysiology in the subfailure regime.

A Nociceptive Role for Integrin Signaling in Pain After Mechanical Injury to the Spinal Facet Capsular Ligament. Ann Biomed Eng 2017; 45:2813-2825.

Abstract
Integrins modulate chemically-induced nociception in a variety of inflammatory and neuropathic pain models. Yet, the role of integrins in mechanically-induced pain remains undefined, despite its well-known involvement in cell adhesion and mechanotransduction. Excessive spinal facet capsular ligament stretch is a common injury that induces morphological and functional changes in its innervating afferent neurons and can lead to pain. However, the local mechanisms underlying the translation from tissue deformation to pain signaling are unclear, impeding effective treatment. Therefore, the involvement of the integrin subunit β1 in pain signaling from facet injury was investigated in complementary in vivo and in vitro studies. An anatomical study in the rat identified expression of the integrin subunit β1 in dorsal root ganglion (DRG) neurons innervating the facet, with greater expression in peptidergic than non-peptidergic DRG neurons. Painful facet capsule stretch in the rat upregulated the integrin subunit β1 in small- and medium-diameter DRG neurons at day 7. Inhibiting the α2β1 integrin in a DRG-collagen culture prior to its stretch injury prevented strain-induced increases in axonal substance P (SP) in a dose-dependent manner. Together, these findings suggest that integrin subunit β1-dependent pathways may contribute to SP-mediated pain from mechanical injury of the facet capsular ligament.

Abstract
BACKGROUND Disorders of the facet joints are some of the most common sources of chronic spinal pain. Facet joint pain is responsible for approximately 50% of patients with chronic neck pain. Pulsed radiofrequency (PRF) stimulation, after placing needle electrodes into the joint space, has been recently reported for the management of joint pain. OBJECTIVE The aim of this study was to evaluate the effect of intraarticular (IA) PRF for the management of cervical facet joint (CFJ) pain. In addition, we compared the effect of IA PRF to IA corticosteroid injection. STUDY DESIGN Prospective observational study. SETTING University hospital. METHODS Forty patients with CFJ pain were included in the study and randomly assigned to one of 2 groups: the IA PRF group and the IA corticosteroid (ICI) group. There were 20 patients in each group. Pain intensity was evaluated using a numeric rating scale (NRS) at pre-treatment, and one, 3, and 6 months after treatment. RESULTS When compared to the pretreatment NRS scores, patients in both groups showed a significant decrease in NRS scores at one, 3, and 6 months after treatment (P = 0.000). Changes in the NRS scores over time were not significantly different between the groups (P = 0.227). Six months after treatment, 10 patients (50.0%) in the PRF group and 12 patients (60.0%) in the ICI group reported successful pain relief (pain relief of = 50%). LIMITATIONS A small number of participants. CONCLUSION IA PRF stimulation is as effective as IA corticosteroid injection in attenuating CFJ pain. The use of PRF could decrease CFJ pain, while avoiding the adverse effects of steroids.Key words: Cervical facet joint pain, pulsed radiofrequency, intraarticular stimulation, chronic pain, corticosteroid injection, numeric rating scale.

Abstract
OBJECTIVE To investigate facet tropism and its role in development of lumbar isthmic spondylolisthesis (IS) in young men. METHODS From March 2013 to May 2016, bilateral facet joint angles were measured axially at L3-4, L4-5, and L5-S1 on lumbar computed tomography (CT) in 97 participants (46 patients with IS and 51 control subjects) 20-29 years old. A difference between the 2 corresponding facet angles of <6° was classified as no tropism; a difference of 6°-12°, moderate tropism; and a difference of >12°, severe tropism. RESULTS We measured 276 facet angles from 46 patients with IS and 306 facet angles from 51 control subjects. For patients with IS, there was no tropism in 43.5% (n = 20), moderate tropism in 50% (n = 23), and severe tropism in 6.5% (n = 3) at L3-4. For L4-5, there was no tropism in 28.3% (n = 13), moderate tropism in 60.9% (n = 28), and severe tropism in 10.9% (n = 5). For L5-S1, there was no tropism in 32.6% (n = 15), moderate tropism in 39.1% (n = 18), and severe tropism in 28.3% (n = 13). For the control group, there was no tropism in 86.3% (n = 44), moderate tropism in 13.7% (n = 7), and no severe tropism at L3-4. For L4-5, there was no tropism in 80.4% (n = 41), moderate tropism in 17.6% (n = 9), and severe tropism in 1.9% (n = 1). For L5-S1, there was no tropism in 68.6% (n = 35), moderate tropism in 29.4% (n = 15), and severe tropism in 1.9% (n = 1). CONCLUSIONS Facet angle tropism is seen in a high proportion of patients with IS and seems to be a predisposing factor in the etiology of IS.

Abstract
This study aimed to systematically compare the safety, effectiveness and radiological changes after lumbar pedicular dynamic stabilisation systems and fusion to treat lumbar degenerative disc disease . All studies that were performed to compare various lumbar pedicular dynamic stabilisation systems with any lumbar fusion to treat lumbar degenerative disc disease and were published until April 30, 2015 were acquired through a comprehensive search in various databases. A meta-analysis was performed after the methodological qualities of trials were assessed and after data were extracted. Sixteen trials with 881 patients with a short-term follow-up (within 2 years) and a middle-term follow-up (2 to 4 years) were identified. Patients treated with lumbar pedicular dynamic stabilisation systems experienced more significant advantages in terms of operation time, intra-operative blood loss, complications and adjacent segment degeneration/disease development than those treated with lumbar fusion. The two groups did not significantly differ in terms of improvement in Oswestry Disability Index, visual analogue scale scores, satisfaction rate of operation and range of motion of adjacent segments. Lumbar pedicular dynamic stabilisation systems is superior to lumbar fusion to some extent, although some of its advantages have yet to be verified and compared with those of lumbar fusion. However, the two interventions were not significantly different in terms of relief in symptoms, functional recovery and motion preservation. Thus, lumbar pedicular dynamic stabilisation systems is recommended for its safety. A prudent attitude is necessary to choose between these interventions on the basis of effectiveness and changes in adjacent segments before a large-scale and long-term follow-up study can be performed.

Abstract
Pyogenic cervical facet joint infections are rare and such infections from a dental origin are even less common. Of these few cases, none have described infection with Streptococcus intermedius as the pathogen. A 65-year-old orthopaedic surgeon complained of fevers, right-sided radiating neck pain, stiffness, swelling, erythema, and right upper extremity weakness one month after he had broken a crown over his right mandibular premolar, a continued source of pain. Imaging of the cervical spine showed a right C4-C5 facet inflammatory arthropathy and a small epidural abscess that was cultured and initially treated with intravenous antibiotics. The oral maxillofacial surgery team performed an extraction of the infected, symptomatic tooth. For continued right upper extremity weakness, the patient underwent C4-C5 laminoforaminotomy and irrigation and debridement of the right C4-C5 facet joint. After 6 weeks of intravenous antibiotics, the patient's infectious and inflammatory markers had normalized. By 4 months, he had regained full strength at his upper extremity and a painless and full range of motion of his cervical spine.Pyogenic cervical facet joint infection is very rare and potentially dangerous. A high clinical suspicion and appropriate imaging, including magnetic resonance imaging, are important for correct diagnosis. Prompt medical and surgical treatment may avert complications, and although the patient presented made a complete recovery, patients may be left with neurological compromise.

Abstract
A retrospective cohort study. Plated cervical laminoplasty is an increasingly common technique. A unique facet joint disturbance induced by lateral mass miniscrews penetrating articular surface was noticed. Facet joints are important to maintain cervical spine stability and kinetic balance. Whether this facet joint disturbance could affect clinical and radiologic results is still unknown. The objective of this study is to investigate the clinical and radiologic outcomes of patients with facet joints disturbance induced by miniscrews in plated cervical laminoplasty.A total of 105 patients who underwent cervical laminoplasty with miniplate fixation between May 2010 and February 2014 were comprised. Postoperative CT images were used to identify whether facet joints destroyed by miniscrews. According to facet joints destroyed number, all the patients were divided into: group A (none facet joint destroyed), group B (1-2 facet joints destroyed), and group C (≥3 facet joints destroyed). Clinical data (JOA, VAS, and NDI scores), radiologic data (anteroposterior diameter and Palov ratio), and complications (axial symptoms and C5 palsy) were evaluated and compared among the groups.There were 38, 40, and 27 patients in group A, B, and C, respectively. The overall facet joints destroyed rate was 30.7%. All groups gained significant JOA and NDI scores improvement postoperatively. The preoperative JOA, VAS, NDI scores, and postoperative JOA scores did not differ significantly among the groups. The group C recorded significant higher postoperative VAS scores than group A (P = 0.002) and B (P = 0.014) and had significant higher postoperative NDI scores than group A (P = 0.002). The pre- and postoperative radiologic data were not significant different among the groups. The group C had a significant higher axial symptoms incidence than group A (12/27 vs 8/38, P = 0.041).Facet joints disturbance caused by miniscrews in plated cervical laminoplasty may not influence neurological recovery and spinal canal expansion, but may negatively affect postoperative axial symptoms.

FACET ORIENTATION AND TROPISM: ASSOCIATION WITH ACCELERATED DEGENERATION OF STABILIZING STRUCTURES IN LOWER LUMBAR SPINE. Acta Clin Croat 2016; 55:117-124.

Abstract
The influence of facet orientation and tropism on the process of spinal degeneration has been extensively studied during the last few decades, but there are still many controversies and conflicting results in this field of research. The biomechanical cause of accelerated degeneration of stabilizing structures in lower lumbar spine lies within the combination of several factors, but two most important ones are compressive load and more coronal facet orientation that offers less resistance against torsional loading. Axial rotation of lower lumbar spine is undoubtedly associated with higher strain in disc annulus, and enhanced range of secondary rotational movements may be even more significant for the progression of annular degeneration. Accordingly, more pronounced facet tropism could be having part in faster progression of disc degeneration in lower lumbar spine, as indicated by a number of recent studies. More sagittal facet orientation in patients with a higher facet osteoarthritis score at lower lumbar segments is very likely related to arthritic remodeling commonly seen in other synovial joints. There is also a possibility that it could be associated with the adaptation to partial loss of lumbar lordosis, as both coincide with advanced age.

Analysis of risk factors for adjacent superior vertebral pedicle-induced facet joint violation during the minimally invasive surgery transforaminal lumbar interbody fusion: a retrospective study. Eur J Med Res 2015; 20:80. [PMID: 26399320 PMCID: PMC4581410 DOI: 10.1186/s40001-015-0174-9] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2015] [Accepted: 09/14/2015] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND The purpose was to explore possible risk factors of facet joint violation induced by adjacent superior vertebral pedicle screw during the minimally invasive surgery transforaminal lumbar interbody fusion (MIS-TLIF). METHODS A total of 69 patients with lumbar degenerative disease, who underwent MIS-TLIF were retrospectively reviewed. Postoperative computed tomography images were used to assess the facet joint violation. The correlation of facet joint violations with gender, age, body mass index (BMI), the adjacent superior vertebral level, fusion segment numbers, position of screw insertion, straight leg-raising test (SLRT) results, clinical diseases and renal dysfunction were analyzed by Chi-square tests and binary logistic regression analysis. RESULTS The incidence of adjacent superior facet joint violations was 25.4 %. Chi-square test showed the patients with age <60 and high BMI (≥30 kg/m(2)) were more prone to have facet joint violations (P = 0.007; P = 0.006). The single segment fusion presented more facet joint violations than the double segments fusion (P = 0.048). The vertebral pedicle screw implant location at L5 showed more facet joint violations compared with that at L3 and L4 (P = 0.035). No correlation was found between gender, screw implant position, SLRT results, clinical diseases and renal dysfunction and facet joint violations. Logistic regression analysis revealed that age <60 years (OR: 2.902; 95 % CI 1.227-6.864; P = 0.015) and BMI ≥30 kg/m(2) (OR: 2.825; 95 % CI 1.191-6.700; P = 0.018 < 0.05) were significantly associated with facet joint violation. CONCLUSION These results found a high incidence of adjacent superior vertebral facet joint violation in the MIS-TLIF. Age <60 and BMI ≥30 kg/m(2) might be risk factors of facet joint violation. Evidence level: Level 4.

Abstract
BACKGROUND Three different types of manual therapy techniques for patients with neck pain and relationship with psychological factors has not been evaluated. AIM To compare the effectiveness high velocity and low amplitude (HVLA) manipulation vs. posteroanterior mobilization (PA mob) vs. sustain appophyseal natural glide (SNAG) in the management of patients with neck pain and to evaluate the interaction with psychological factors. STUDY DESING Randomized clinical trial. SETTING Primary Health Care Center. POPULATION Patients with history of chronic neck pain over the last 3 months were recruited. METHODS Patients were randomly assigned to receive treatment with HVLA (N.=15), with PA mob (N.=16) or with SNAG (N.=17). One session was applied. Pain intensity of neck pain, pressure pain threshold over processus spinosus of C2 (PPT_C2) and cervical range of motion (CROM) were measured pre- and post-intervention. Pain catastrophizing, depression, anxiety and kinesiophobia were assessed in baseline. ANOVAs were performed, with main effects, two-way (treatment x time) and three-way interactions (treatment x psychological variable x time) were examined. RESULTS Fourthy-eight patients (mean±SD age, 36.5±8.7 years; 87.5% female). A significant interaction treatment x time was observed for VAS-rest in HVLA and AP mob groups (P<0.05). With more pain relief to HVLA and AP mob groups than SNAG groups but all groups improve the same in CROM. Also, a significant three-way treatment x anxiety x time interaction for VAS in Flexion/Extension was identified (P<0.01), and a trend toward significance was observed for the three way treatment x anxiety x time interaction, with respect to CROM in Lateral-Flexion movement (P<0.05). CONCLUSION The results suggest that an HVLA and PA mob groups relieved pain at rest more than SNAG in patients with Neck pain. Among psychological factors, only trait anxiety seems interact with Manual therapy, mainly high anxiety conditions interact with the Mobilization and SNAG effects but under low anxiety conditions interact with the HVLA effects. Significant mean differences can be observed both in VAS in Flexion/Extension and in CROM in lateral-flexion movement when using mobilization under high anxiety conditions CLINICAL REHABILITATION IMPACT The findings provide preliminary evidence to support that three different techniques have similar immediate effects over neck pain and while under high anxiety levels a better outcome is expected after mobilization intervention, under low anxiety levels a better prognosis is expected after manipulation and SNAG intervention.

Abstract
PURPOSE The purpose of this study was to evaluate and compare the biomechanical behavior of the lumbar spine after posterior decompression with the spinous process osteotomy (SPiO) technique or the conventional laminectomy (CL) technique using a finite element (FE) model. MATERIALS AND METHODS Three validated lumbar FE models (L2-5) which represented intact spine and two decompression models using SPiO and CL techniques at the L3-4 segment were developed. In each model, the ranges of motion, the maximal von Mises stress of the annulus fibrosus, and the intradiscal pressures at the index segment (L3-4) and adjacent segments (L2-3 and L4-5) under 7.5 Nm moments were analyzed. Facet contact forces were also compared among three models under the extension and torsion moments. RESULTS Compared to the intact model, the CL and SPiO models had increased range of motion and annulus stress at both the index segment (L3-4) and the adjacent segments under flexion and torsion. However, the SPiO model demonstrated a reduced range of motion and annulus stress than the CL model. Both CL and SPiO models had an increase of facet contact force at the L3-4 segment under the torsion moment compared to that of the intact model. Under the extension moment, however, three models demonstrated a similar facet contact force even at the L3-4 model. CONCLUSION Both decompression methods lead to postoperative segmental instability compared to the intact model. However, SPiO technique leads to better segmental stability compared to the CL technique.

Is sub-occipital padding necessary to maintain optimal alignment of the unstable spine in the prehospital setting? A preliminary report. J Emerg Med 2013; 45:366-71.

Abstract
BACKGROUND As prehospital emergency rescuers prepare cervical spine-injured adult patients for immobilization and transport to hospital, it is essential that patients be placed in a favorable position. Previously, it was recommended that patients with cervical spine injuries be immobilized in a slightly flexed position using pads placed beneath the head. However, it is unknown how neck flexion created with pad placement affects the unstable spine. OBJECTIVE To determine the effects of three different head positions on the alignment of unstable vertebral segments. METHODS Five cadavers with a complete segmental instability at the C5 and C6 level were included in the study. The head was either placed directly on the ground (or spine board) or on foam pads. Three conditions were tested: no pad; pads 2.84 cm thick; and pads 4.26 cm thick. Pads were positioned beneath the head to determine their effect on spinal alignment. Anterior-posterior translation, flexion-extension motion, and axial displacement across the unstable segment were compared between conditions. RESULTS Although statistical tests failed to identify any significant differences between pad conditions, some meaningful results were noted. In general, the "no pad" condition aligned the spine in a position that best replicated the intact spine. CONCLUSIONS Because the goal of emergency rescuers is to conserve whatever physiologic or structural integrity of the spinal cord and spinal column that remains, the outcome of this study suggests that this goal may be best achieved using the "no pad" condition. However, it is recommended that more research be conducted to confirm these preliminary findings.

Abstract
BACKGROUND Up to now, plain radiographs are not well suited to assess spinal fusion. Radiostereometric analysis performed for two postures may deliver more reliable results. However, it is unknown, which postures are most suitable for this procedure. METHODS In a finite element study, spinal fusion at the level L4-5 was simulated assuming a posterior approach and the implantation of two cages and a spinal fixation device. The change of the distance between markers in vertebrae adjacent to the cages was calculated for moving from one of the following postures standing, flexion, extension, axial rotation, lying, and extension in a lying position to another. The changes of marker distances were calculated for the intact model, as well as for the situations: directly after surgery before fusion started, in the early-fusion-phase and in the late-fusion-phase. Differences in the marker motion between two postoperative situations were also calculated. FINDINGS The most anteriorly placed markers showed the greatest motion between two postures. The greatest differences in marker motions between the two situations before-fusion and early-fusion-phase (0.54 mm) as well as between early-fusion-phase and late-fusion-phase (0.34 mm) were found for the two postures flexion while standing and extension in a lying position. INTERPRETATION Pairs of X-rays taken while standing with maximum flexed upper body and while lying with maximum extended trunk are most suited for the assessment of spinal fusion when using radiostereometric analysis.

Abstract
Pain originating from the lumbar facet joints is estimated to represent about 15% of all low back pain complaints. The diagnostic block is considered to be a valuable tool for confirming facetogenic pain. It was demonstrated that a block of the ramus medialis of the ramus dorsalis is preferred over an intra-articular injection. The outcome of the consequent radiofrequency treatment is not different in patients reporting over 80% pain relief after the diagnostic block than in those who have between 50% and 79% pain relief. There is one well-conducted comparative trial assessing the value of one or two controlled diagnostic blocks to none. The results of the seven randomized trials on the use of radiofrequency treatment of facet joint pain demonstrate that good patient selection is imperative for good clinical outcome. Therefore, we suggest one block of the ramus medialis of the ramus dorsalis before radiofrequency treatment.

Abstract
INTRODUCTION The internal efforts in the human body in motion could provide valuable information for the evaluation and follow-up of subjects with musculo-skeletal pathologies, such as scoliosis, but are still difficult to accurately measure. In this context, the objective of this study is to compare the lombo-sacral (L5-S1) joint efforts during gait (i.e.: mediolateral forces, mediolateral torques, and anteroposterior torques) between typically developed adolescents (TDA) and adolescents with left lumbar or thoracolumbar idiopathic scoliosis (AIS), categorized by their Cobb angle (CA). MATERIAL AND METHODS 12 TDA, 10 AIS with CA < 20°, 13 AIS with CA between 20° and 40° as well as 16 AIS in preoperative condition performed gait at 4 km/h on instrumented treadmill. Among the latter group, 8 AIS were evaluated after surgical intervention (participants with at least a diminution of 30° of their CA). The acquisition system measured the human body joint motion via optokinetic sensors, and the ground reaction forces via a treadmill fitted with force sensors. The L5-S1 intervertebral efforts were calculated using a tridimensional inverse dynamical model of the human body. RESULTS The mediolateral forces were significantly higher for AIS with CA between 20° and 40° and for AIS in pre-operative condition compared to TDA values. But neither mediolateral nor anteroposterior torque was significantly different between groups. After surgical intervention the maximal anteroposterior torque was significantly lower compared to pre-surgical value. CONCLUSION The participants with severe idiopathic scoliosis present higher L5-S1 mediolateral forces than TDA, which could lead to a supplementary asymmetric vertebra growth modulation and the progression of the scoliotic deformities in the framework of the Hueter-Volkman principle. Further research should include the tridimensional reconstruction of the spine in order to observe differences between categories of AIS patients in terms of dynamical behaviors along the spine.

Abstract
In idiopathic scoliotic patients, dynamical intervertebral efforts acting between vertebrae seem to be correlated with the spinal deformity. The quantification of these efforts, which is useful for the orthopedic surgeons to set up their surgical planning is the final objective of the present research. As a first step, we focus in this contribution on the geometrical reconstruction of the spine and especially on the rotation sequences between vertebrae in a multibody approach. The reconstruction process is performed in the standing position with possible bending, using an optimization process based on geometrical data reconstructed from radiographs. The obtained results will serve as input for the subsequent gait motion for which the limited set of geometrical information must be compensated.

Abstract
Magnetic resonance imaging of patients with intervertebral disk herniation was used to study the stages of degenerative and dystrophic processes in the spinal structures in the presence of intervertebral disk protrusion and herniation. Differences were found in the pathobiomechanical mechanisms in the spinal motor segments of herniation and protrusion in the area of their localization and in the adjacent spinal motor segments. Among the symptoms traditionally analyzed, joint facet joint arthritis and arthrosoarthritis classified as spondyloarthritis by radiodiagnosis were examined for their impact on the rate of herniation and protrusion.

Abstract
Disorders of lumbosacral (LS) facet joints are manifested by low back pain with or without referred leg pain and decreased mobility of the LS spine (LS facet syndrome). The most frequent causes of LS facet syndrome are functional disorders (functional blockade or dysfunction of facet joint=reversible restriction of facet joint movements caused by meniscoid entrapment) and degenerative changes of facet joints while the others are less frequent (spondyloarthropathies, infection, tuberculosis, synovial cyst, injury). Although it has been proven that the facet joints are one of the most frequent sources of chronic low back pain (15-45%), the fact is that the facet syndrome has been frequently overlooked in patients with chronic low back pain. Following are the main reasons for explaining why the facet syndrome has been overlooked in patients with chronic low back pain: 1. Facet joints disorders are manifested by non-specific clinical picture, 2.Diagnosis of facet syndrome cannot be established by either the conventional clinical examination or radiological examinations, 3. A very small number of doctors are practicing manual functional examination which can establish the diagnosis of facet joint dysfunction and 4. Diagnostic anesthetic block which can confirm the facet syndrome diagnosis is not a widely accessible method. There is a lack of research in frequency of facet syndrome in patients with acute low back pain. Chronic mechanical low back pain caused by dysfunction of several structurally unchanged facet joints can have the same features as the inflammatory pain which can result in misdiagnosis of spondyloarthropathy. Acute LS facet syndrome caused by dysfunction of facet joints responds very well to manual therapy. The most important therapeutic options in patients with chronic LS facet syndrome caused by degenerative changes and/or dysfunction of facet joints are manual therapy, kinesiotherapy (flexion exercises), therapeutic blocks and radiofrequency denervation. The article describes etiopathogenesis, clinical manifestations, diagnosis, differential diagnosis and therapy of LS facet syndrome with emphasis on functional disorders of facet joints that can cause particular diagnostic and therapeutic problems.

Abstract
PURPOSE Lumbar facet joint syndrome (LFJS) is the cause of pain in 15-54% of the patients with low-back pain. There are few studies of cryotherapy for LFJS, focusing mainly on pain scores rather than further outcome measures. The aim of the study was to determine the long-term outcome after cryoneurolysis of lumbar facet joints, looking at pain scores, pain-related impairment patient satisfaction, and pain-related anxiety/depression. METHODS The study design was a retrospective observational study. In a 4-year period, 117 cryoneurolyses were performed in 91 patients under CT guidance in the prone position. Data from patient charts and questionnaires pre- and post-treatment were evaluated. RESULTS The mean pain rating sank from 7.70 before treatment to 3.72 post treatment. In the post-interventional 3 months follow-up, this value rose to 4.22. At follow-up (mean 1.7 years, range 6-52 months), the mean visual analogue scale (VAS) was 4.99. The pain disability index revealed statistically significant improvements in the following items: familiar and domestic duties, recreation, social activities, profession and vitally indispensable activities (p < 0.05). Hospital anxiety and depression scale (HADS) scores for depression showed a statistically significant decline after therapy, whereas scores for anxiety did not. A subgroup of patients who did not benefit from cryoneurolysis had elevated depression scores. CONCLUSIONS Cryoneurolysis for LFJS can lead to favourable results with sustained pain relief, amelioration of pain-related disability and reduction of depression scores.

Abstract
The novel transsacral fusion system AxiALIF allows stabilization of the lumbosacral junction. The system consists of a screw with two different diameters. With additional facet screws or internal fixation devices 360° fusion can be achieved. The effects of different parameters such as length, diameter combination and material of the transsacral screw, type of additional fixation and stiffness of the bone are unknown. In a probabilistic finite element analysis, the input parameters were randomly varied. The rotational angles and the axial forces in the various implants were calculated for four different load scenarios. In a subsequent sensitivity study the influences of single input parameters on the variance of the results were calculated. A transsacral screw significantly reduces the motion in the treated segment, except for axial rotation. An additional fixation has a strong effect on the variance of rotation angles. The other parameters usually explain less than 10% of the variance. The novel lumbosacral fusion system allows good stabilization of the segment, especially when additional fixation via facet screws or fixators is performed.

Abstract
OBJECTIVE To study the effect of vertebrae semi-dislocation on the stress distribution in facet joint and interuertebral disc of patients with cervical syndrome using three dimensional finite element model. METHODS A patient with cervical spondylosis was randomly chosen, who was male, 28 years old, and diagnosed as cervical vertebra semidislocation by dynamic and static palpation and X-ray, and scanned from C(1) to C(7) by 0.75 mm slice thickness of CT. Based on the CT data, the software was used to construct the three dimensional finite element model of cervical vertebra semidislocation (C(4)-C(6)). Based on the model,virtual manipulation was used to correct the vertebra semidislocation by the software, and the stress distribution was analyzed. RESULTS The result of finite element analysis showed that the stress distribution of C(5-6) facet joint and intervertebral disc changed after virtual manipulation. CONCLUSION The vertebra semidislocation leads to the abnormal stress distribution of facet joint and intervertebral disc.

Abstract
Synovial cysts, typically observed in the lumbar spine eventually associated with degenerative changes of the facet joints, only rarely present in the cervical spine. Up to now, only 28 symptomatic cases are described in literature. Typically, the treatment of these cases is a decompressive laminectomy followed by complete surgical removal of the lesion. The authors present the case of an 84-year-old man with a symptomatic synovial cyst involving the space between C7 and T1.

Spinal neuroarthropathy associated with Guillain-Barré syndrome. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2010; 19 Suppl 2:S108-13. [PMID: 19707801 PMCID: PMC2899632 DOI: 10.1007/s00586-009-1131-5] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/02/2009] [Revised: 06/28/2009] [Accepted: 07/30/2009] [Indexed: 12/01/2022]
Abstract
Since the rarefaction of neurosyphilis, axial neuroarthropathy is mostly secondary to spinal cord pathologies. Peripheral manifestations of neuroarthropathy resulting from Guillain-Barré syndrome have already been reported but to our knowledge, this is the first case of a patient diagnosed with axial involvement. After the acute phase, a 47-year-old woman suffered of paraparesia with a partial loss of sensibility under the tenth thoracic vertebra. As a consequence, she developed first of all neuroarthropathy of both knees and few years later, a spinal involvement was discovered. Multiple surgeries of both knees and of the spine were required, due to non-union, relapse, and infection. Natural evolution of Charcot spine remains unknown. Surgical treatment is recommended but even with circumferential fusion, failures do frequently occur. This observation allows us to report an original case and to discuss the etiology of axial neuroarthropathy, the classical radiographic findings, and the inherent difficulties of its treatment.

Making sense of the accuracy of diagnostic lumbar facet joint nerve blocks: an assessment of the implications of 50% relief, 80% relief, single block, or controlled diagnostic blocks. Pain Physician 2010; 13:133-143.

Abstract
BACKGROUND The presence of lumbar facet joint pain has been overwhelmingly supported and the accuracy of controlled diagnostic blocks has been demonstrated in multiple studies and confirmed in systematic reviews. However, controversy surrounds the following related issues: placebo control, the amount of relief (50% versus 80%), single block versus double block, and placebo or comparative control. STUDY DESIGN An observational report of an outcome study to establish the diagnostic accuracy of controlled lumbar facet joint nerve blocks. SETTING An interventional pain management practice setting in the United States. OBJECTIVE To determine the accuracy of controlled diagnostic blocks in managing lumbar facet joint pain at the end of 2 years, with 2 different criteria (50% or 80% relief) and single block versus double block. METHODS A previous study of 152 patients showed an 89.5% of sustained diagnosis of lumbar facet joint pain at the end of a 2-year follow-up period when the diagnosis was made with double blocks and at least 80% relief. The present evaluation includes comparison of the above results with a study of 110 patients undergoing lumbar facet joint nerve blocks with positive criteria of at least 50% relief and follow-up of 2 years. The inclusion criteria in both studies was based on a positive response to diagnostic controlled comparative local anesthetic lumbar facet joint blocks, with either 50% or 80% relief and the ability to perform previously painful movements. The treatment in both groups included therapeutic lumbar facet joint interventions either with facet joint nerve blocks or radiofrequency neurotomy. OUTCOME MEASURES The sustained diagnosis of lumbar facet joint pain at the end of one year and 2 years based on pain relief and functional status improvement. RESULTS At the end of one year, the diagnosis was confirmed in 75% of the group with 50% relief, whereas it was 93% in the group with 80% relief. At the end of the 2-year follow-up, the diagnosis of lumbar facet joint pain was sustained in 51% of the patients in the group with 50% relief, whereas it was sustained in 89.5% of the patients with 80% relief. The results differed between 50% relief and 80% relief with prevalence of 61% facet joint pain with dual blocks with 50% relief, and 31% with dual blocks with 80% relief; whereas with only a single block, the prevalence was 73% with 50% relief and 53% in the 80% relief group. LIMITATIONS The study is limited by its observational nature. CONCLUSION Controlled diagnostic lumbar facet joint nerve blocks are valid utilizing the criteria of 80% pain relief and the ability to perform previously painful movements, with a sustained diagnosis of lumbar facet joint pain in at least 89.5% of the patients at the end of a 2-year follow-up. In contrast, the diagnosis was sustained in 51% of the patients with 50% relief at the end of 2 years. Thus, inappropriate diagnostic criteria will increase the prevalence of facet joint pain substantially, leading to inappropriate and unnecessary treatment.

Abstract
BACKGROUND One technique in radiofrequency neurotomies uses 2 electrodes that are simultaneously placed to lie parallel to one another. Comparing lesions on cadaveric interspinous ligament tissue and measuring the temperature change in egg white allows us to accurately measure quantitatively the area of the lesion. METHODS Fresh cadaver spinal tissue and egg white tissue were used. A series of samples were prepared with the electrodes placed 1 to 7 mm apart. Using radiofrequency, the needle electrodes were heated in sequential or simultaneous order and the distance of the escaped lesion area and temperature were measured. RESULTS Samples of cadaver interspinous ligament showed sequential heating of the needles limits the placement of the needle electrodes up to 2 mm apart from each other and up to 4 mm apart when heated simultaneously. The temperature at the escaped lesion area decreased according to the distance for egg white. There was a significant difference in temperature at the escaped lesion area up to 6 mm apart and the temperature was above 50 degrees celsius up to 5 mm in simultaneous lesion and 3 mm in the sequential lesion. LIMITATIONS The limitations of this study include cadaveric experimentation and use of intraspinous ligament rather than medial branch of the dorsal ramus which is difficult to identify. CONCLUSION Heating the 2 electrodes simultaneously appears to coagulate a wider area and potentially produce better results in less time.

Relationship of facet tropism with degeneration and stability of functional spinal unit. Yonsei Med J 2009; 50:624-9.

Abstract
PURPOSE The authors investigated the effect of lumbar facet tropism (FT) on intervertebral disc degeneration (DD), facet joint degeneration (FJD), and segmental translational motion. MATERIALS AND METHODS Using kinetic MRI (KMRI), lumbar FT, which was defined as a difference in symmetry of more than 7 degrees between the orientations of the facet joints, was investigated in 900 functional spinal units (300 subjects) in flexion, neutral, and extension postures. Each segment at L3-L4, L4-L5, and L5-S1 was assessed based on the extent of DD (grade I-V) and FJD (grade 1-4). According to the presence of FT, they were classified into two groups; one with FT and one with facet symmetry. For each group, demographics, DD, FJD and translational segmental motion were compared. RESULTS The incidence of FT was 34.5% at L3-L4, 35.1% at L4-L5, and 35.2% at L5-S1. Age and gender did not show any significant relationship with FT. Additionally, no correlation was observed between DD and FT. FT, however, was found to be associated with a higher incidence of highly degenerated facet joints at L4-L5 when compared to patients without FT (p < 0.01). Finally, FT was not observed to have any effects upon translational segmental motion. CONCLUSION No significant correlation was observed between lumbar FT and DD or translational segmental motion. However, FT was shown to be associated significantly with the presence of high grades of FJD at L4-L5. This suggests that at active sites of segmental motion, FT may predispose to the development of facet joint degeneration.

Abstract
BACKGROUND Lumbar facet joint pain is diagnosed by controlled diagnostic blocks. The accuracy of controlled diagnostic blocks has been demonstrated in multiple studies and confirmed in systematic reviews. Controlled diagnostic studies have shown an overall prevalence of lumbar facet joint pain in 31% of the patients with chronic low back pain without disc displacement or radiculitis, with an overall false-positive rate of 30% using a single diagnostic block. STUDY DESIGN An observational report of outcomes assessment. SETTING An interventional pain management practice setting in the United States. OBJECTIVE To determine the accuracy of controlled diagnostic blocks in managing lumbar facet joint pain at the end of 2 years. METHODS This study included 152 patients diagnosed with lumbar facet joint pain using controlled diagnostic blocks. The inclusion criteria was based on a positive response to diagnostic controlled comparative local anesthetic lumbar facet joint blocks. The treatment included therapeutic lumbar facet joint nerve blocks. OUTCOME MEASURES The sustained diagnosis of lumbar facet joint pain at the end of one year and 2 years based on pain relief and functional status improvement. RESULTS At the end of one year 93% of the patients and at the end of 2 years 89.5% of the patients were considered to have lumbar facet joint pain. LIMITATIONS The study is limited by its observational nature. CONCLUSION Controlled diagnostic lumbar facet joint nerve blocks are valid utilizing the criteria of 80% pain relief and the ability to perform previously painful movements, with sustained diagnosis of lumbar facet joint pain in at least 89.5% of the patients at the end of a 2-year follow-up period.

C2-fractures: part II. A morphometrical analysis of computerized atlantoaxial motion, anatomical alignment and related clinical outcomes. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2009; 18:1135-53. [PMID: 19224254 PMCID: PMC2899496 DOI: 10.1007/s00586-009-0901-4] [Citation(s) in RCA: 23] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/06/2008] [Revised: 11/09/2008] [Accepted: 01/24/2009] [Indexed: 01/22/2023]
Abstract
Knowledge on the outcome of C2-fractures is founded on heterogenous samples with cross-sectional outcome assessment focusing on union rates, complications and technical concerns related to surgical treatment. Reproducible clinical and functional outcome assessments are scant. Validated generic and disease specific outcome measures were rarely applied. Therefore, the aim of the current study is to investigate the radiographic, functional and clinical outcome of a patient sample with C2-fractures. Out of a consecutive series of 121 patients with C2 fractures, 44 met strict inclusion criteria and 35 patients with C2-fractures treated either nonsurgically or surgically with motion-preserving techniques were surveyed. Outcome analysis included validated measures (SF-36, NPDI, CSOQ), and a functional CT-scanning protocol for the evaluation of C1-2 rotation and alignment. Mean follow-up was 64 months and mean age of patients was 52 years. Classification of C2-fractures at injury was performed using a detailed morphological description: 24 patients had odontoid fractures type II or III, 18 patients had fracture patterns involving the vertebral body and 11 included a dislocated or a burst lateral mass fracture. Thirty-one percent of patients were treated with a halo, 34% with a Philadelphia collar and 34% had anterior odontoid screw fixation. At follow-up mean atlantoaxial rotation in left and right head position was 20.2 degrees and 20.6 degrees, respectively. According to the classification system of posttreatment C2-alignment established by our group in part I of the C2-fracture study project, mean malunion score was 2.8 points. In 49% of patients the fractures healed in anatomical shape or with mild malalignment. In 51% fractures healed with moderate or severe malalignment. Self-rated outcome was excellent or good in 65% of patients and moderate or poor in 35%. The raw data of varying nuances allow for comparison in future benchmark studies and metaanalysis. Detailed investigation of C2-fracture morphology, posttreatment C2-alignment and atlantoaxial rotation allowed a unique outcome analysis that focused on the identification of risk factors for poor outcome and the interdependencies of outcome variables that should be addressed in studies on C2-fractures. We recognized that reduced rotation of C1-2 per se was not a concern for the patients. However, patients with worse clinical outcomes had reduced total neck rotation and rotation C1-2. In turn, C2-fractures, especially fractures affecting the lateral mass that healed with atlantoaxial deformity and malunion, had higher incidence of atlantoaxial degeneration and osteoarthritis. Patients with increased severity of C2-malunion and new onset atlantoaxial arthritis had worse clinical outcomes and significantly reduced rotation C1-2. The current study offers detailed insight into the radiographical, functional and clinical outcome of C2-fractures. It significantly adds to the understanding of C2-fractures.

Abstract
PURPOSE To explore musculoskeletal findings in patients with cervicogenic dizziness and how these findings relate to pain and dizziness. To study treatment effects and long-term symptom progress. METHOD Twenty-two patients (20 women, 2 men; mean age 37 years) with suspected cervicogenic dizziness underwent a structured physical examination before and after physiotherapy guided by the musculoskeletal findings. Questionnaires were sent to the patients six months and two years after treatment. RESULTS Dorsal neck muscle tenderness and tightness was found in a majority of the patients. Zygapophyseal joint tenderness was found at all cervical levels. Cervical range of motion was equal to or larger than expected age and gender matched values. The cervico-thoracic region was often hypomobile. Most patients had postural imbalance. Dynamic stabilization capacity was reduced. Suboccipital muscles tightness correlated with posture imbalance and poor neck stability. The treatment resulted in reduced tenderness in levator scapula, high and middle paraspinal and temporalis muscles and zygapophyseal joints at C4-C7 and increased cervico-thoracic mobility. Reduction of middle paraspinal muscle tenderness correlated with neck pain relief. Postural alignment improved, as did dynamic stabilization in trunk, neck and shoulders. After 6 months, 13 of the 17 patients had still no or less neck pain and 14 had no or less dizziness. After 2 years, 7 patients had no or less neck pain and 11 no or less dizziness. CONCLUSION Patients with suspected cervicogenic dizziness have some musculoskeletal findings in common. Treatment based on these findings reduces neck pain as well as dizziness long-term but some patients might need a maintenance strategy.

Abstract
BACKGROUND Understanding the neurophysiological basis of chronic spinal pain and diagnostic interventional techniques is crucial in the proper diagnosis and management of chronic spinal pain. Central to the understanding of the structural basis of chronic spinal pain is the provision of physical diagnosis and validation of patient symptomatology. It has been shown that history, physical examination, imaging, and nerve conduction studies in non-radicular or discogenic pain are unable to diagnose the precise cause in 85% of the patients. In contrast, controlled diagnostic blocks have been shown to determine the cause of pain in as many as 85% of the patients. OBJECTIVE To provide evidence-based clinical practice guidelines for diagnostic interventional techniques. DESIGN Best evidence synthesis. METHODS Strength of evidence was assessed by the U.S. Preventive Services Task Force (USPSTF) criteria utilizing 5 levels of evidence ranging from Level I to III with 3 subcategories in Level II. DIAGNOSTIC CRITERIA Diagnostic criteria established by systematic reviews were utilized with controlled diagnostic blocks. Diagnostic criteria included at least 80% pain relief with controlled local anesthetic blocks with the ability to perform multiple maneuvers which were painful prior to the diagnostic blocks for facet joint and sacroiliac joint blocks, whereas for provocation discography, the criteria included concordant pain upon stimulation of the target disc with 2 adjacent discs producing no pain at all. RESULTS The indicated level of evidence for diagnostic lumbar, cervical, and thoracic facet joint nerve blocks is Level I or II-1. The indicated evidence is Level II-2 for lumbar and cervical discography, whereas it is Level II-3 for thoracic provocation discography. The evidence for diagnostic sacroiliac joint nerve blocks is Level II-2. Level of evidence for selective nerve root blocks for diagnostic purposes is Level II-3. LIMITATIONS Limitations of this guideline preparation include a continued paucity of literature and conflicts in preparation of systematic reviews and guidelines. CONCLUSION These guidelines include the evaluation of evidence for diagnostic interventional procedures in managing chronic spinal pain and recommendations. However, these guidelines do not constitute inflexible treatment recommendations. These guidelines also do not represent a "standard of care."

Abstract
Approximately 80% of the adult population suffers from chronic lumbar pain with episodes of acute back pain. The aetiology of this disorder can be very extensive: degenerative scoliosis, spondiloarthritis, disc hernia, spondylolysis, spondylolisthesis and, in the most serious cases, neoplastic or infectious diseases. For several years, the attention of surgeons was focused on the articular facets syndrome (Lilius et al. in J Bone Joint Surg (Br) 71-B:681-684, 1998), characterised clinically by back pain and selective pressure soreness at the level of the facets involved. The instrumental framework highlights widespread zigoapophysary arthritis and hypertrophy/degeneration of articular facets due to a functional overload. This retrospective study analyses the patients who arrived at our observation and were treated with a neuroablation using a pulsed radiofrequency procedure, after a CT-guided infiltration test with anaesthetic and cortisone. From the data collected, it would seem that this procedure allows a satisfactory remission of the clinical symptoms, leaving the patient free from pain; furthermore, this method can be repeated in time.

Abstract
Quantitative sensory testing has indicated generalized muscle hyperalgesia in patients with chronic low back pain. The temporal development of such hyperalgesia is not well understood. The aim of the present study was to demonstrate whether generalized muscle hyperalgesia can develop within minutes of acute low back pain using a new experimental model of lumbar facet joint pain. Thirteen healthy volunteers were included and baseline pressure pain thresholds were assessed at eight separate sites, outside the area of evoked low back and referred pain. Using ultrasonography, two electrode needles were placed either side of a lumbar facet joint (right L3-4) and used to induce experimental low back pain for 10 min with continuous stimulation. Thresholds, stimulus-response relationships, distribution and quality of the electrically induced pain were recorded. Electrical facet joint stimulation induced low back pain and pain referral into the anterior leg, ipsilaterally, proximal to the knee, similar to what is observed clinically. Pressure pain thresholds did not change significantly before, during and after facet joint stimulation. In conclusion, we describe a novel model of acute experimental low back pain and demonstrate that generalized hyperalgesia did not develop within minutes of acute low back pain.

Abstract
BACKGROUND Radiofrequency neurolysis is a common technique used in the treatment of chronic pain, particularly facet (zygapophyseal joint) arthralgia. A needle-like cannula is insulated except for the exposed active tip, which is positioned as parallel and adjacent as possible to the targeted nerve branch. Via an inserted probe connected to a radiofrequency generator, energy flowing from the tip of the cannula creates a heat lesion in the 80 - 85 degree Celsius range mostly about the length of the exposed active tip and in proportion to the diameter of the probe. The common active tip lengths used for neurolysis are 5mm or 10mm. The cannulae are FDA approved. The manufacturer advises physicians not to bend or otherwise modify a cannula prior to use. The cannulae are available straight or bent, sharp and blunt. The technique is guided under C-arm fluoroscopy. X-rays passing through the patient demonstrate in 2 dimensions the projected relative radio-opaque bony landmarks and the metallic cannula. Most currently available cannulae are uniform in their radio-opacity from tip to hub. The physician must make an educated guess as to the portion of the cannula that will be making the lesion in relationship to the bony landmark. OBJECTIVE A new radiofrequency cannula with a radio-opaque marker (ROC) delineates the proximal end of the active tip. The cannula was used in a phantom model. Images were reproduced with explanation of the potential advantage of the new device. RESULT The marker on the new cannula was visible and did help delineate the active tip as well as its orientation. It was also helpful in making sequential lesions at the same nerve using a "tip to tail" repositioning technique. CONCLUSION The ROC did represent an improvement over standard cannulae to optimize visualization of cannula and thus lesion placement using a phantom model. The applications described were only for conventional or "hot" RF.

Abstract
BACKGROUND Chronic mid back and upper back pain caused by thoracic facet joints has been reported in 34% to 48% of the patients based on the responses to controlled diagnostic blocks. Systematic reviews have established moderate evidence for controlled comparative local anesthetic blocks of thoracic facet joints in the diagnosis of mid back and upper back pain, moderate evidence for therapeutic thoracic medial branch blocks, and limited evidence for radiofrequency neurotomy of therapeutic facet joint nerves. OBJECTIVES To determine the clinical utility of diagnostic and therapeutic thoracic facet joint interventions in diagnosing and managing chronic upper back and mid back pain. STUDY DESIGN Systematic review of diagnostic and therapeutic thoracic facet joint interventions. METHODS Review of the literature for utility of facet joint interventions in diagnosing and managing facet joint pain was performed according to the Agency for Healthcare Research and Quality (AHRQ) criteria for diagnostic studies and observational studies and the Cochrane Musculoskeletal Review Group criteria as utilized for interventional techniques for randomized trials. The level of evidence was classified as Level I, II, or III based on the quality of evidence developed by United States Preventive Services Task Force (USPSTF) for therapeutic interventions. Recommendations were based on the criteria developed by Guyatt et al. Data sources included relevant literature of the English language identified through searches of Medline and EMBASE from 1966 to July 2008 and manual searches of bibliographies of known primary and review articles. Results of the analysis were performed for diagnostic and therapeutic interventions separately. OUTCOME MEASURES For diagnostic interventions, studies must have been performed utilizing controlled local anesthetic blocks. For therapeutic interventions, the primary outcome measure was pain relief (short-term relief = up to 6 months and long-term relief > 6 months) with secondary outcome measures of improvement in functional status, psychological status, return to work, and reduction in opioid intake. RESULTS Based on the controlled comparative local anesthetic blocks, the evidence for the diagnosis of thoracic facet joint pain is Level I or II-1. The evidence for therapeutic thoracic medial branch blocks is Level I or II-1. The recommendation is IA or 1B/strong for diagnostic and therapeutic medial branch blocks. CONCLUSION The evidence for the diagnosis of thoracic facet joint pain with controlled comparative local anesthetic blocks is Level I or II-1. The evidence for therapeutic facet joint interventions is Level I or II-1 for medial branch blocks. Recommendation is 1A or 1B/strong for diagnostic and therapeutic medial branch blocks.

Abstract
This article reviews the evidence for several common interventional techniques for the treatment of chronic pain, including: intraspinal delivery of analgesics, reversible blockade with local anesthetics, augmentation with spinal cord stimulation, and ablation with radiofrequency energy or neurolytic agents. The role of these techniques is defined within the framework of a multidisciplinary approach to the neurobehavioral syndrome of chronic pain. Challenges to the study of the analgesic efficacy of procedural interventions are explored, as are the practical issues raised by their clinical implementation, with the aim of helping nonspecialist physicians identify the patients most likely to benefit from these approaches.

Lumbar Facet Joint Osteoarthritis: A Review. Semin Arthritis Rheum 2007; 37:69-80.

Abstract
OBJECTIVES The facet joints (FJ) can be a potentially important source of symptoms because of the high level of mobility and load forces, especially in the lumbar area. We reviewed the anatomy, biomechanics, and possible sources of pain of the FJ, natural history, and risk factors of lumbar FJ osteoarthritis and briefly reviewed the relevant imaging methods. METHODS PubMed and MEDLINE databases (1950-2006) were searched for the key words "facet joints," "zygapophyseal joints," "osteoarthritis," "low back pain," and "spondyloarthritis." All relevant articles in English were reviewed. Pertinent secondary references were also retrieved. RESULTS The FJ play an important role in load transmission; they provide a posterior load-bearing helper, stabilizing the motion segment in flexion and extension and also restricting axial rotation. The capsule of the FJ, subchondral bone, and synovium are richly innervated and can be a potential source of the low back pain. Degenerative changes in the FJ comprise cartilage degradation that leads to the formation of focal and then diffuse erosions with joint space narrowing, and sclerosis of the subchondral bone. Because the most prominent changes occur in bone, the best method of evaluation of the FJ is computed tomography. Risk factors for lumbar FJ osteoarthritis include advanced age, relatively more sagittal orientation of the FJ, and a background of intervertebral disk degeneration. CONCLUSIONS An up-to-date knowledge of this subject can be helpful in the development of diagnostic techniques and in the prevention of lumbar FJ osteoarthritis and low back pain and can assist in the determination of future research goals.
