OBJECTIVES: The presence of trigger points (MTrPs) and pressure pain sensitivity has been well documented in subjects with neck and back pain; however, it has yet to be examined in people with upper thoracic spine pain. The purpose of this study was to investigate the presence of MTrPs and mechanical pain sensitivity in individuals with upper thoracic spine pain. METHODS: Seventeen subjects with upper thoracic spine pain and 17 pain-free controls without spine pain participated...

Sauropodomorphs are the most abundant and diverse clade of Triassic dinosaurs, but the taxonomy of their earliest (Carnian) representatives is still poorly understood. One such taxon is Pampadromaeus barberenai, represented by a nearly complete disarticulated skeleton recovered from the upper part of the Santa Maria Formation of Rio Grande do Sul, Brazil. Here, the osteology of Pam. barberenai is fully described for the first time. Detailed comparisons with other Carnian sauropodomorphs reveal a unique anatomy, corroborating its status as a valid species...

Peggy Vincent, Glenn W Storrs
This paper offers a re-description of one of the oldest (Lower Hettangian, Lower Jurassic) plesiosaurians (Reptilia: Sauropterygia) from Germany and discusses its phylogenetic relevance. Lindwurmia thiuda, new genus and species, is a moderately sized plesiosaur (estimated size between 2 and 3 m long) exhibiting several plesiomorphic features. Although it presents a short and robust premaxillary rostrum, constricted at the premaxilla-maxilla suture as observed in Rhomaleosauridae, its skull and skeleton share a great number of characters with basal sauropterygians and basal plesiosaurians: premaxillae and maxillae in contact posterior to the external nares, absence of contact between the vomers and the maxillae posterior to the internal nares, cervical zygapophyses wider than the vertebral centrum width and curved anterior border of the humerus...

Chronic low-back pain (CLBP) has an increasing incidence and yields a tremendous health economic burden. There are different anatomic structures that may be responsible for CLBP, such as lumbar intervertebral discs, sacroiliac joints, nerve root dura, fascia, ligaments, and muscles. However, to a large extent, CLBP is associated with structural changes in and around the facet (zygapophyseal) joint. If conservative treatment strategies fail, symptoms and pain can effectively be reduced by denervation or rhizotomy of the medial branch of the dorsal ramus of the spinal nerve through radiofrequency ablation...

BACKGROUND: There is a paucity of literature studying therapeutic intraarticular zygapophyseal (commonly referred to as facet) joint injections in the atraumatic patient population. As a result of this, intraarticular injections have been dismissed as a possible treatment for cervical zygapophyseal joint-mediated pain. Radiofrequency neurotomy (RFN) is currently the accepted treatment for facet joint neck pain. OBJECTIVE: This prospective observational study investigated injection response in an atraumatic population to determine treatment viability and whether injections reduce the need for RFN in neck pain patients...

OBJECTIVE: The purpose of the current randomized clinical trial was to examine the effects of cervical thrust manipulation or sham manipulation on cervicocephalic kinaesthetic sense, pain, pain-related disability, and pressure pain sensitivity in patients with mechanical neck pain. METHODS: Fifty-four individuals with neck pain were randomly assigned to receive either a cervical manipulation (right or left) or a sham manipulation. Immediate outcomes included cervical kinesthetic sense as assessed by joint position sense error (JPSE) and pressure pain thresholds (PPTs)...

BACKGROUND: With a life-time prevalence of 39%, low back pain (LBP) is one of the most common musculoskeletal disorders. Correct diagnosis of underlying causes is commonly seen as a prerequisite for successful therapy of LBP. Currently, there is no useful, non-invasive clinical test to diagnose painful lumbar zygapophyseal joints. Clinical tests with high diagnostic accuracy are therefore desirable. Inter-rater reliability is commonly seen as a prerequisite of test validity. The objective of this pilot study was thus to evaluate inter-rater reliability of new clinical pain provocation tests for diagnosing painful lumbar zygapophyseal joints...

The present study aimed to verify the presence of stem cells with multilineage differentiation potential in human lumbar zygapophyseal articular cartilage (LZAC) and to compare the chondrogenic potential of cells obtained from differentially degenerated articular cartilage samples. Surgically obtained human lumbar zygapophyseal joint tissues were classified into the normal, mildly degenerated and severely degenerated groups, according to their pathological characteristics. Primary chondrocytes from these groups were cultured, and stem cells were selected using a monoclonal cell culture method...

Background: Knowledge about the assessment reliability of common cervical spine changes is a prerequisite for precise and consistent communication about Magnetic Resonance Imaging (MRI) findings. The purpose of this study was to determine the inter- and intra-rater reliability of degenerative findings when assessing cervical spine MRI. Methods: Fifty cervical spine MRIs from subjects with neck pain were used. A radiologist, a chiropractor and a second-year resident of rheumatology independently assessed kyphosis, disc height, disc contour, vertebral endplate signal changes, spinal canal stenosis, neural foraminal stenosis, and osteoarthritis of the uncovertebral and zygapophyseal joints...

The paper reports on the first detailed vertebral and rib morphology of anguine taxon Pseudopus apodus using micro-computed tomography. A comparison shows significant morphological differences of vertebrae of Pseudopus relative to those of Anguis and Ophisaurus. Usually, there are 55 presacral vertebrae, two sacral and 95-97 caudal vertebrae. Pseudopus apodus can be defined by 23 diagnostic features concerning the vertebral column. Although zygapophyseal articulation between atlas and axis is well developed in limbed anguid gerrhonotine lizards like Abronia or Barisia, it is absent in the extant representatives of the clade Anguinae, which are limbless...

Inflammatory arthritis is documented for the first time in snakes. Ossification of the intervertebral capsule and zygapophyseal joints resulting in segmental vertebral fusion was observed in the aquatic Cretaceous snake Lunaophis aquaticus. Such pathologic alterations are pathognomonic for the spondyloarthropathy form of inflammatory arthritis. A survey of 2144 snakes in recent collections, performed to identify Holocene prevalence, revealed only two occurrences in extant snakes. The findings in Bitis gabonica and Elaphe taeniura were indistinguishable from those noted in Lunaophis aquaticus and identical to those previously recognized in modern varanids...

STUDY DESIGN: Cross-sectional study. PURPOSE: To evaluate the association between zygapophyseal joint angle (ZJA), facet tropism (FT), and lumbar intervertebral disc prolapse (IVDP). OVERVIEW OF LITERATURE: Several studies have shown that FT increases the risk of IVDP and have postulated that a more sagittally oriented zygapophyseal joint provides less mechanical resistance to axial torque, thereby exerting excessive rotational strain on the intervertebral disc, resulting in an annular tear...

Stagonolepis robertsoni , from the Late Triassic of Scotland, was the first named aetosaurian. Known mostly from a series of natural molds from two localities, the osteology of this taxon has been difficult to interpret. Detailed work on this material in the late 1950s resulted in a monograph that set the standard for the understanding of aetosaurians, making Stagonolepis robertsoni the best known aetosaurian; however, little has been done with this material since. Reanalysis of this material shows that despite its limitations the early 1960s reconstruction work depicts the preserved characteristics faithfully, especially in the skull...

BACKGROUND: Visual analgesia refers to the phenomena where people report decreased pain intensity when they see the painful or painfully stimulated body part. Alongside pain, sensorimotor impairment (i.e., disturbed proprioception) is also evident in chronic pain. This study aims to investigate whether real-time visual feedback offers additional pain relief and proprioceptive improvement when used in combination with recommended therapies in neck pain patients who received manual therapy with or without real-time visual feedback...

BACKGROUND: Neural blockade of the cervical medial branches is a validated procedure in the diagnosis and treatment of cervical zygapophyseal joint pain. Fluoroscopic visualization of the lower cervical medial branch target zones (CMBTZs) in lateral view is sometimes challenging or not possible due to the patient's shoulders obscuring the target. Large shoulders and short necks often exacerbate the problem. Clear visualization is critical to accuracy and safety. OBJECTIVE: We aim to describe a method for optimal fluoroscopic visualization of the lower CMBTZs using a modified swimmer's view...
