Abstract
Pain-related massage, important in traditional Eastern medicine, is increasingly used in the Western world. So the widening acceptance demands continual safety assessment. This review is an evaluation of the frequency and severity of adverse events (AEs) reported mainly for pain-related massage between 2003 and 2013. Relevant all-languages reports in 6 databases were identified and assessed by two coauthors. During the 11-year period, 40 reports of 138 AEs were associated with massage. Author, year of publication, country of occurrence, participant related (age, sex) or number of patients affected, the details of manual therapy, and clinician type were extracted. Disc herniation, soft tissue trauma, neurologic compromise, spinal cord injury, dissection of the vertebral arteries, and others were the main complications of massage. Spinal manipulation in massage has repeatedly been associated with serious AEs especially. Clearly, massage therapies are not totally devoid of risks. But the incidence of such events is low.

Abstract
Abstract
Mostly associated with degenerative facet joints and spondylolisthesis, symptomatic lumbar juxta facet cysts - ganglion and synovial cysts are uncommon lesions of the spine. They can mimic herniated discs, causing low back pain, radiculopathy or even cauda equina syndrome; also some of them are associated with spinal instability. Referring to a case with hemicauda equina syndrome where microsurgical decompression was performed with very good result; alternative treatment solutions are discussed: conservative therapy for symptomatic lesions is often unsuccessful, spinal fusion should be made for those cases with spinal instability, although there are reports of spontaneous resolution of these cysts as well as the symptoms associated with them.

Abstract
OBJECTIVE The purpose of this study was to systematically search the literature for studies reporting serious adverse events following lumbopelvic spinal manipulative therapy (SMT) and to describe the case details. METHODS A systematic search was conducted in PubMed including MEDLINE, EMBASE, CINAHL, and The Cochrane Library up to January 12, 2012, by an experienced reference librarian. Study selection was performed by 2 independent reviewers using predefined criteria. We included cases involving individuals 18 years or older who experienced a serious adverse event following SMT applied to the lumbar spine or pelvis by any type of provider (eg, chiropractic, medical, physical therapy, osteopathic, layperson). A serious adverse event was defined as an untoward occurrence that results in death or is life threatening, requires hospital admission, or results in significant or permanent disability. We included studies published in English, German, Dutch, and Swedish. RESULTS A total of 2046 studies were screened, and 41 studies reporting on 77 cases were included. Important case details were frequently unreported, such as descriptions of SMT technique, the pre-SMT presentation of the patient, the specific details of the adverse event, time from SMT to the adverse event, factors contributing to the adverse event, and clinical outcome. Adverse events consisted of cauda equina syndrome (29 cases, 38% of total); lumbar disk herniation (23 cases, 30%); fracture (7 cases, 9%); hematoma or hemorrhagic cyst (6 cases, 8%); or other serious adverse events (12 cases, 16%) such as neurologic or vascular compromise, soft tissue trauma, muscle abscess formation, disrupted fracture healing, and esophageal rupture. CONCLUSIONS This systematic review describes case details from published articles that describe serious adverse events that have been reported to occur following SMT of the lumbopelvic region. The anecdotal nature of these cases does not allow for causal inferences between SMT and the events identified in this review. Recommendations regarding future case reporting and research aimed at furthering the understanding of the safety profile of SMT are discussed.

Abstract
BACKGROUND AND PURPOSE Synovial cysts of the spine occur most frequently in the lumbosacral region. Methods of treatment vary, but in cases of chronic pain or neurological deficits surgical intervention is undertaken. The aim of this paper is to present indications, surgical technique and efficacy of surgical treatment in patients with synovial cyst of the spinal canal. MATERIAL AND METHODS The retrospective analysis included 11 patients, aged from 47 to 72 years, treated at the Department of Neurosurgery and Neurotraumatology, Poznan University of Medical Sciences, between 2004 and 2009. The length of medical history ranged from 2 months to 6 years. Conservative treatment applied before surgery was not effective. Neurological examination revealed unilateral or bilateral sciatica, superficial sensory disturbance or lower limb paresis. RESULTS Synovial cysts were located mainly at the L4-L5 level (9 cases). Magnetic resonance imaging (MRI) of the spine was performed in all patients and showed the cystic lesion attached to the intervertebral joint. Surgical treatment consisted of a unilateral fenestration using microsurgical techniques in most cases. Back pain relief was observed in 9 cases. In 10 patients, symptoms of sciatica disappeared. Neurological deficits disappeared in 5 patients. CONCLUSIONS Surgical treatment of spinal synovial cysts is safe, effective and ensures a long-lasting effect. Surgical treatment is indicated in patients in whom the clinical symptoms correlate with the presence of synovial cyst in imaging studies and do not resolve after conservative treatment.

Abstract
OBJECTIVES Juxtafacet cysts (JFCs) of the subaxial cervical spine are rare causes of neurological deficits. Their imaging characteristics, relationship to segmental instability, and potential for inducing acute symptomatic deterioration have only been described in a few case reports and small case series. The objective of the current study was to review the surgical experience at our center and across the literature to better define these variables. METHODS A single-institution, multisurgeon series of 12 consecutive patients (mean age 63.4 years, range 52-83 years) harboring 14 JFCs treated across 9 years was retrospectively reviewed. Clinical history, neurological status, preoperative imaging, operative findings, pathology, and postoperative outcomes were obtained from medical records. The mean follow up was 9.2 ± 7.8 months. A literature review identified 35 studies with 89 previously reported cases of surgically treated subaxial cervical JFCs. RESULTS Consistent with previously reported cases, most JFCs in our series involved the C7/T1 level. Nine patients reported axial neck pain, 12 patients had radicular symptoms, four patients had myelopathy, and one patient experienced rapid neurological decline attributable to cystic hemorrhage. Cyst expansion without hemorrhage caused subacute deterioration in one patient. All patients experienced sensory and/or motor improvement following surgical decompression. Preoperative axial neck pain improved in eight of nine patients (89 %). Seven out of 12 patients (58 %) underwent fusion either at the time of decompression (six patients) or at a delayed timepoint within the follow-up period (one patient). Prior history of cervical instrumentation, hypermobility on dynamic imaging, and other risk factors for segmental instability were more common in our series than in previous reports. CONCLUSIONS Our findings lead us to advocate for early decompression rather than prolonged conservative treatment, for pre- and postoperative dynamic imaging, and for fusion in selected cases as an initial surgical consideration.

Abstract
The facet joint is a crucial anatomic region of the spine owing to its biomechanical role in facilitating articulation of the vertebrae of the spinal column. It is a diarthrodial joint with opposing articular cartilage surfaces that provide a low friction environment and a ligamentous capsule that encloses the joint space. Together with the disc, the bilateral facet joints transfer loads and guide and constrain motions in the spine due to their geometry and mechanical function. Although a great deal of research has focused on defining the biomechanics of the spine and the form and function of the disc, the facet joint has only recently become the focus of experimental, computational and clinical studies. This mechanical behavior ensures the normal health and function of the spine during physiologic loading but can also lead to its dysfunction when the tissues of the facet joint are altered either by injury, degeneration or as a result of surgical modification of the spine. The anatomical, biomechanical and physiological characteristics of the facet joints in the cervical and lumbar spines have become the focus of increased attention recently with the advent of surgical procedures of the spine, such as disc repair and replacement, which may impact facet responses. Accordingly, this review summarizes the relevant anatomy and biomechanics of the facet joint and the individual tissues that comprise it. In order to better understand the physiological implications of tissue loading in all conditions, a review of mechanotransduction pathways in the cartilage, ligament and bone is also presented ranging from the tissue-level scale to cellular modifications. With this context, experimental studies are summarized as they relate to the most common modifications that alter the biomechanics and health of the spine-injury and degeneration. In addition, many computational and finite element models have been developed that enable more-detailed and specific investigations of the facet joint and its tissues than are provided by experimental approaches and also that expand their utility for the field of biomechanics. These are also reviewed to provide a more complete summary of the current knowledge of facet joint mechanics. Overall, the goal of this review is to present a comprehensive review of the breadth and depth of knowledge regarding the mechanical and adaptive responses of the facet joint and its tissues across a variety of relevant size scales.

Abstract
BACKGROUND AND IMPORTANCE Intraspinal synovial cysts are uncommon causes of back and radicular leg pain. Usually associated with degenerative spinal disease, these juxtafacet cysts are usually located in the lumbar spine and may rarely undergo intracystic hemorrhage. The pathogenesis of these cysts are unclear, and risk factors that may contribute to hemorrhagic complications are largely unknown. CLINICAL PRESENTATION A 68-year-old man presented to the clinic 4 months after a fall on ice with persistent back pain and lumbar radiculopathy. A week after the initial clinic consultation, the patient presented to the emergency room with increased pain and worsening weakness in the left foot. An emergent magnetic resonance image showed thecal sac compression secondary to a large, juxtafacet cyst that was hyperintense on T1-weighted and hypointense on T2-weighted images. Lumbar decompressive laminectomies were performed at L3 and L4 with cyst removal and stabilization. CONCLUSION We present the eighth reported case of a hemorrhagic juxtafacet cyst secondary to physical trauma, the second in which the patient's symptoms acutely worsened several months after the initial insult without new trauma. We also present summary statistics of the 31 cases of hemorrhagic juxtafacet cysts reported in the literature and propose a putative mechanism that may account for the development and progression of symptoms in some patients.

Abstract
BACKGROUND CONTEXT With improvements in neurological imaging, there are increasing reports of symptomatic spinal synovial cysts. Surgical excision has been recognized as the definitive treatment for symptomatic juxtafacet cysts. However, the role for concomitant fusion and the incidence of recurrent back pain and recurrent cyst formation after surgery remain unclear. PURPOSE To determine the cumulative incidence of postoperative symptomatic relief, recurrent back and leg pain after cyst resection and decompression, and synovial cyst recurrence. STUDY DESIGN Systematic review of the literature. PATIENT SAMPLE All published studies to date reporting outcomes of synovial cyst excision with and without spinal fusion. OUTCOME MEASURES Cyst recurrence and Kawabata, Macnab, Prolo, or Stauffer pain scales. METHODS We performed a systematic literature review of all articles published between 1970 and 2009 reporting outcomes after surgical management of spinal synovial cysts. RESULTS Eighty-two published studies encompassing 966 patients were identified and reviewed. Six hundred seventy-two (69.6%) patients presented with radicular pain and 467 (48.3%) with back pain. The most commonly involved spinal level was L4-L5 (75.4%), with only 25 (2.6%) and 12 (1.2%) reported synovial cysts in the cervical or thoracic area, respectively. Eight hundred eleven (84.0%) patients were treated with decompressive surgical excision alone, whereas 155 (16.0%) received additional concomitant spinal fusion. Six hundred fifty-four (92.5%) and 880 (91.1%) patients experienced complete resolution of their back or leg pain after surgery, respectively. By a mean follow-up of 25.4 months, back and leg pain recurred in 155 (21.9%) and 123 (12.7%) patients, respectively. Sixty (6.2%) patients required reoperation, of which the majority (n=47) required fusion for correction of spinal instability and mechanical back pain. Same-level synovial cyst recurrence occurred in 17 (1.8%) patients after decompression alone but has been reported in no (0%) patients after decompression and fusion. CONCLUSIONS Surgical decompression results in symptomatic resolution in the vast majority of patients; however, recurrent back pain occurs in a significant number of patients. Cyst recurrence occurs in less than 2% of patients but has never been reported after cyst excision with concomitant fusion. The lack of cyst recurrence after concomitant fusion supports the need to investigate the value of fusion of the involved motion segment in the treatment of symptomatic synovial cysts of the spine.

Abstract
STUDY DESIGN Retrospective study. OBJECTIVE Compare outcomes of different treatment methods for intraspinal synovial cysts. SUMMARY OF BACKGROUND DATA Intraspinal synovial cysts are cited as an increasing cause of back pain and radiculopathy. To date, few studies have compared outcomes of differing treatment methods in patients with synovial cysts. METHODS We retrospectively reviewed 167 consecutive patients undergoing surgical management of 195 symptomatic synovial cysts at a single institution over 19 years. The incidence of postoperative mechanical back pain, radiculopathy, and cyst recurrence was compared between patients undergoing unilateral hemilaminectomy (n = 51), bilateral laminectomy (n = 39), facetectomy with in situ fusion (n = 18), and facetectomy with instrumented fusion (n = 56). RESULTS A total of 155 (97.5%) patients presented with radiculopathy, 132(82.5%) with mechanical back pain, 31 (20%) with neurogenic claudication, and 5 (3.2%) with bladder dysfunction. Most cysts occurred in the lumbar spine. After surgery, back and radicular pain improved in 91.6% and 91.9% patients, respectively. By a mean follow-up of 16 +/- 9 months, 36 (21.6%) patients developed recurrent back pain, 20 (11.8%) recurrent leg pain, and 5 (3%) recurrent synovial cysts. Patients undergoing laminectomy had a significantly increased cyst recurrence incidence compared to fusion groups via log-rank test (P = 0.042), and this risk was decreased to baseline with instrumented fusion on reoperation. Laminectomy was also associated with the highest increased risk of recurrent back pain in both log-rank test (P = 0.018) and proportional hazards regression (HR): 1.64 (1.00-3.45), P = 0.05. Instrumented fusion had the lowest risk for back pain recurrence. CONCLUSION Hemilaminectomy or laminectomy remains one of the mainstay surgical treatments for symptomatic intraspinal synovial cysts. Our experience shows that the majority of patients undergoing decompression/excision of synovial cysts will have immediate improvement in back and leg pain. However, within 2 years, patients receiving hemilaminectomy or laminectomy alone have an increased incidence of back pain and cyst recurrence. Decompression with instrumented fusion appears to be associated with the lowest incidences of cyst recurrence or back pain.

Abstract
We present 4 cases of facet cyst haematoma in the ligamentum flavum of the lumbar spine. All patients presented with a one-to-3-month history of back pain or numbness in the legs, and sudden neurological deterioration. One also developed cauda equina syndrome and another developed radiculopathy. In all cases, magnetic resonance imaging showed a mass with high signal intensity on both T1- and T2-weighted images. Facet arthrography and computed tomography revealed communication between the mass and the neighbouring facet joint. The haematomas were removed en bloc with the ligamentum flavum. They were surrounded by the ligament and contained degenerated and lacerated elastic fibres but no synovial lining cells. Facet cyst haematoma is so-named because of bleeding from tissue adjacent to the facet joint into a pre-existing facet cyst.

Abstract
OBJECTIVE The majority of lumbar facet joint cysts (LFJCs) are located in the spinal canal, on the medial aspect of the facet joint with characteristic diagnostic features. When they migrate away from the joint of origin, they cause diagnostic problems. MATERIALS AND METHODS In a 7-year period we examined by computed tomography (CT) and magnetic resonance (MR) imaging five unusual cases of facet joint cysts which migrated from the facet joint of origin. RESULTS Three LFJCs were identified in the right S1 foramen, one in the right L5-S1 neural foramen and one in the left erector spinae and multifidus muscles between the levels of L2-L4 spinous process. CONCLUSIONS Awareness that spinal lesions identified at MRI and CT could be due to migrating facet joint cyst requires a high level of suspicion. The identification of the appositional contact of the cyst and the facet joint needs to be actively sought in the presence of degenerative facet joints.

Abstract
Juxtafacet cysts are lesions that are associated with spinal facet joints. Although these lesions are frequently noted as incidental findings on imaging studies of the spine, they may produce symptoms in some patients. Juxtafacet cysts can mimic herniated discs, resulting in symptoms from focal nerve root and/or spinal cord compression. Some of these lesions are associated with spinal instability, and patients may require spinal fusion to address this underlying disorder. Conservative therapy for symptomatic lesions is often unsuccessful, although there are reports of spontaneous resolution of these cysts as well as the symptoms associated with them. Surgical therapy should be focused on decompression of the lesions causing nerve root compression and the accompanying symptoms, while recognizing that instability requiring fusion may be present in some but not all cases.
