Abstract
We present a two-part review article on the current state of knowledge of lumbar facet joint pathology. This first article discusses the functional anatomy, biomechanics, and radiological grading systems currently in use in clinical practice and academic medicine. Facet joint degeneration is presented within the larger context of degenerative disc disease to enable the reader to better understand the anatomical changes underlying facet-mediated lower back pain. Other less-common, but equally important etiologies of lumbar facet joint degeneration are reviewed. The existing grading systems are discussed with specific reference to the reliability of CT and MR imaging in the diagnosis of lumbar facet osteoarthritis. It is hoped that this discussion will stimulate debate on how best to improve the diagnostic reliability of these tests so as to improve both operative and non-operative treatment outcomes.

Abstract
Symptomatic intraspinal lumbar facet joint synovial cysts can be managed both conservatively and surgically. Diagnosis of the lumbar facet joint cyst is made through cross-sectional imaging of the spine, either by computerized tomography (CT) scan, myelography, or most commonly magnetic resonance imaging. Conservative treatment by facet joint injection can be performed under fluoroscopic or CT guidance, although only CT guidance provides direct visualization of the cyst confirming accurate needle placement. This case report illustrates the use of percutaneous CT-guided facet joint cyst treatment as a temporizing measure or alternative to surgical treatment in the proper clinical scenario.

Abstract
Object
Although many cases of primary intraspinal facet cysts in the lumbar spine have been reported, there have only been a few reports of postoperative intraspinal facet cysts in the lumbar spine. The purpose of this study was to investigate the prevalence and clinical features of postoperative intraspinal facet cysts in the lumbar spine.
Methods
Data from 81 patients undergoing microendoscopic posterior decompression to treat lumbar spinal stenosis were reviewed. The development of a postoperative intraspinal facet cyst was observed using MR imaging during 1 year after surgery. If the patient demonstrated a postoperative intraspinal facet cyst, additional MR imaging was performed to evaluate the natural course of the cyst. Furthermore, the authors conducted a comparative evaluation to identify the factors associated with the causes of cyst development.
Results
A postoperative intraspinal facet cyst developed in 7 patients (8.6%) during 1 year after surgery. Spondylotic spinal stenosis, degenerative spondylolisthesis, and degenerative scoliosis were revealed before surgery in 2, 4, and 1 patient, respectively. In 5 patients, the cysts developed within 3 months after surgery. Although 3 patients exhibited symptoms caused by cyst development, all symptoms were relieved by conservative treatment. On radiographic evaluations, postoperative segmental spinal instability, including a progression of spondylolisthesis and disc degeneration, was revealed in 6 (86%) of the 7 patients. Spontaneous regression of the cysts was observed in 5 (71%) of these 7 patients. On comparative evaluation of patients with and without postoperative intraspinal facet cysts, the presence of segmental spinal instability before surgery (including degenerative spondylolisthesis) and the appearance of postoperative segmental spinal instability were related to the development of the cysts.
Conclusions
The prevalence of postoperative intraspinal facet cysts, including asymptomatic cysts, was 8.6% during 1 year after decompression surgery for lumbar spinal stenosis. The development of postoperative intraspinal facet cysts was related to the presence of segmental spinal instability before surgery (including degenerative spondylolisthesis) and postoperative segmental spinal instability, including a progression of spondylolisthesis and disc degeneration after surgery. A postoperative intraspinal facet cyst, which can be expected to regress spontaneously with a probability > 50%, should be recognized as one of the postoperative complications of decompression surgery for lumbar spinal stenosis.

Abstract
The field of spinal injection procedures is growing at a tremendous rate. Many disciplines are involved, including radiology, anesthesiology, orthopedics, physiatry and rehabilitation medicine, as well as other specialties. However, there remains tremendous variability in the assessment of patients receiving these therapies, methods for evaluation of outcome, and in the understanding of where these procedures belong in the triaging of those who require surgery. In this article, we attempt to highlight the biologic concepts on which these therapies are based, controversies that have arisen with their increasing use, and a description of complications that have been reported.

Abstract
A 6-year-old neutered male Rottweiler had chronic episodic signs of thoracolumbar pain and inability to stand that did not improve after rest and nonsteroidal antiinflammatory medication. In magnetic resonance images, an extradural mass was identified between the spinal cord and the T13/L1 intervertebral disc; the mass was compressing the cord in a dorsoventral direction. The lesion had a low signal intensity rim that enhanced slightly after gadolinium administration, and contents with similar signal intensity to cerebrospinal fluid. The lesion was removed surgically by severing its attachments to the annulus fibrosus. The histologic diagnosis was degenerative intraspinal cyst. The origin of such cysts, and their relationship to synovial and ganglion cysts is discussed.

Abstract
STUDY DESIGN A retrospective analysis of the frequency and etiology of dural tears (DT), defined as an unintended incidental intraoperative durotomy, occurring in 110 predominantly geriatric patients undergoing multilevel laminectomies with noninstrumented fusions. OBJECTIVE To document the frequency and etiology of DT occurring in these older patients. SUMMARY OF BACKGROUND DATA The frequency and etiology of DT occurring in older patients are not well documented. METHODS The clinical (including comorbidities), neurodiagnostic, surgical procedures, and Short-Form 36 outcomes (questionnaires administered preoperatively, and 3, 6, 12 mo postoperatively) were retrospectively analyzed for these 110 patients with/without DT. RESULTS Intraoperative DT occurred in 10 of 110 patients. These patients were typically older (average 74 y with fistulas vs. 69 y old without fistulas), included a higher percentage of females (90% vs. 76%), and had undergone somewhat more extensive laminectomies (5.5 vs. 5.0 levels) with noninstrumented fusions (1.8 vs. 1.6 levels). Three factors seemed to contribute to DT. Marked ossification of the yellow ligament (OYL), documented in all 10 patients with DT, extended to and through the dura in 3 patients. For the 100 patients without DT, 57 exhibited moderate/hypertrophied yellow ligament and 22 showed marked OYL. Synovial cysts with marked OYL were observed in 5 of 10 patients with DT, whereas only 8 of 100 without DT had synovial cysts. Prior surgical scar, originally anticipated to be a major contributing factor to DT, was found in only 2 of 10 patients with DT (also with marked OYL) compared with 10% without DT. Short-Form 36 outcome data revealed improvement on 4 or 5 Health Scales over the first postoperative year for both populations. CONCLUSIONS Ten of 110 patients undergoing multilevel laminectomies and noninstrumented fusions developed unintended incidental DT attributed to OYL extending to/through the dura (3 patients), postoperative scar/marked OYL (2 patients), and synovial cysts/marked OYL (5 patients).

Abstract
OBJECTIVE This article presents a case in which synovial cysts appeared to cause compromise of the neural foramina and thecal sac with presenting neurological signs. CLINICAL FEATURES A 67-year-old female patient with a history of lumbar synovial cysts and synovectomy presented with recurrence of bilateral low back, leg pain, and apparent neurological compromise along with a recurrence of lumbar synovial cyst as evidenced on magnetic resonance images. INTERVENTIONS AND OUTCOME Flexion distraction therapy, performance of Williams low back exercises and interferential therapy resulted in 50% relief. Frequency of care was progressively diminished as she improved. The patient experienced recurrence of severe episodes; multifidi strengthening exercises were provided to address a concomitant spondylolisthesis and instability, resulting in a cessation of these episodes and improvement in functional activities. CONCLUSION Distraction therapy seemed to alleviate the constant pain without surgical intervention. In this case, the synovial cyst may have been an incidental finding versus a primary cause of the low back and leg pain. For similar patients, in the absence of correlative progressive neurological signs, surgical intervention may not be necessary.

Abstract
Retrospective analysis of 10 cases of resection of symptomatic lumbar juxtafacet cysts in nine patients (mean age 65.4 years) investigated the relationship between surgical method and progression of spinal spondylolisthesis or cyst recurrence. Patient characteristics, surgical methods, and postoperative course were reviewed. The most common preoperative symptom, painful radiculopathy, occurred in all cases, followed by motor weakness in five, sensory loss in four, and intermittent claudication in four. All patients underwent bilateral total (n = 6) or partial laminectomy (n = 4), with minimal (n = 3) or no (n = 7) facetectomy. Cysts were gross totally resected in eight cases and partially resected in two. Concomitant fixation was not performed. Painful radiculopathy, motor weakness, and sensory disturbance all resolved, resulting in good or excellent outcome in all patients. Postoperative symptomatic spondylolisthesis had not been noted at mean 52.1 months postoperatively. However, new juxtafacet cysts were later detected on the contralateral side to the initial lesion in two patients. Surgical removal of juxtafacet cysts is recommended for immediate symptomatic relief. Concomitant spinal fixation to prevent progression of spinal spondylolisthesis or cyst recurrence depends on cyst size, involvement of surrounding structures, degree of preoperative spondylolisthesis, and facet joint destruction.

Abstract
Object
The authors define facet cyst as a cyst located beside the facet joint and exhibiting a communication with the joint, as demonstrated on arthrography and subsequent computed tomography (CT) of the joint space. The purpose of this study was to determine the pathogenesis of facet cysts based on their radiological and histological features.
Methods
Forty-six juxtafacet cysts in 45 patients (26 men and 19 women, age range 41–82 years) were surgically treated after evaluation by arthrography and subsequent CT scanning. A communication channel between the cyst and the joint was confirmed in all cases and thus the lesions were designated facet cysts. In almost all patients the involved facet joint showed moderate to severe degeneration. After a thorough preoperative radiological evaluation, these cysts were excised en bloc by medial facetectomy with the entire ligamentum flavum. The specimens were cut axially at the maximum diameter and were histologically investigated.
Morphologically, the cysts exhibited three shapes, appearing as: 1) a small protrusion, 2) a semicircular cyst, or 3) a round cyst. The cyst walls consisted of elastic and collagen fibers undergoing fibrinoid degeneration, but no synovial lining cells were detected. The cystic cavities were regularly filled with fibrinoids, and myxoid degeneration was found particularly in the larger cysts.
Conclusions
Facet cysts are closely related to the degeneration of the neighboring facet joint. Analysis of the findings in this histological study suggests that there are several shapes of facet cysts. The authors propose that the shape could depend on the stage of the cyst’s development.

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.
