Neurogenic arthropathy is a rare joint disorder, characterized by rapid progression and marked destruction of articular surfaces (known as Charcot's joint) with only mild to moderate pain. Most cases are related to diabetic neuropathy, but they may complicate the course of other neurogenic clinical conditions such as neurosyphilis (tabes dorsalis), syringomyelia, myelomeningocele, Peroneal Muscular Atrophy, spine or peripheral nerve injury, alcoholism and avitaminosis. Loss of superficial sensation and proprioception plays a pivotal role in development of arthropathy because it affects the joint's normal protective reflexes and leads to joint instability, degeneration and destruction. The authors describe an unusual case of bilateral neurogenic hip arthropathy in a 61-year old women who developed this condition in the course of multilevel lumbar spondylosis with spinal and nerve root compression. The patient underwent a successful bilateral hip replacement and remains almost asymptomatic contrary to literature reports that suggest high risk of complications after the operative treatment of Charcot's joints.

OBJECTIVE: The objective of our study was to retrospectively compare the radiography and MRI findings of unilateral spondylolysis in the upper lumbar segment and in the lower lumbar segment and to consider how these radiologic findings can be applied in the diagnosis of unilateral spondylolysis. MATERIALS AND METHODS: Thirty patients with unilateral lumbar spondylolysis were categorized into one of two groups according to the lumbar levels involved with pars interarticularis defects: group A (L1, L2, and L3) or group B (L4 and L5). On radiographs, we evaluated contour bulging of the affected pars interarticularis, reactive sclerosis in the contralateral pedicle, anterolisthesis of the involved vertebra, and deviation of the spinous process. On MRI, we assessed pseudoarticulation of the pars interarticularis defect, uneven distribution of posterior epidural fat, the interspinous distance between adjacent segments, facet and disk degeneration in adjacent segments, and other anomalous changes. RESULTS: Among the 63 patients with unilateral spondylolysis, the upper lumbar segment was involved in 29 and the lower lumbar segment, in 34. Group A often displayed contour bulging of the affected pars interarticularis, reactive sclerosis of the contralateral pedicle, and contralateral deviation of the spinous process, all of which were easily detectable on radiography. Group B frequently showed anterolisthesis, pseudoarticulation of the pars interarticularis defect, adjacent facet-disk degeneration, and other anomalous changes that were well observed on MRI. CONCLUSION: Unilateral lumbar spondylolysis displayed radiologic differences in morphology of the isthmic defect itself and in ancillary findings of the adjacent structures based on the segment involved. Recognition of different ancillary features of unilateral spondylolysis with the use of a feasible diagnostic tool can be helpful for the diagnosis of cases in which a direct sign of isthmic defect is equivocal.

AIM: Current guides recommend to evaluate the patients with low back pain complaints with initial clinical assessment and history, and to utilize radiological or other imaging technics, in case of possible diagnosis. The aim of this study was to compare the findings of radiological and clinical assessment, and validate the reliability of spondylolisthesis diagnosed with clinical assessment. This study is conducted on 100 patients with, and 30 patients without (control group) radiological diagnosis of spondylolisthesis, who had applied to Department of Physical Therapy and Rehabilitation, Haydarpasa Numune Hospital with low back pain complaints in one and a half year. Clinic assessment was consisted of 20 parameters including examinations of motor system such as, sign of slipping observed on palpation and inspection, extension of trunk and increase in lumbar lordosis. Antero-posterior, lateral, oblique and lateral flexion/extension radiographies were used for radiological assessment. Slipping degree and lumbar lordosis angle were measured. RESULTS: Women/men patients ratio was 91/9 in spondylolisthesis group and 22/8 in control group. Age of 69% of patients were 50 and over. In both groups, sciatalgia was observed in more than half of the patients, and no significant difference was detected in localization (p > 0.05). In clinical assessment, weak and drooping abdominal wall, paravertebral muscle hypertrophy, increase in lumbar lordosis, sign of slipping observed on palpation and inspection, hamstring muscle spasm, pain during lateral trunk flexion-extension tasks and during double leg raising task were found to be positively correlated with radiological assesment (p < 0.05). CONCLUSION: In our study, a systematic clinical assessment was proved to be useful in determination of possible spondylolisthesis cases. Radiological assessments are required in order to make the diagnosis clear and to determine the grade and prognosis of spondylolisthesis. Advanced imaging techniques like MRI and CT have to be used when neurological symptoms are present, and when surgical intervention is indicated.

OBJECTIVES: The aim of this pilot study was to test the generally believed hypothesis that intervertebral disc degeneration is a prerequisite for degenerative spondylolisthesis (DS). METHODS: This cross-sectional study was an ancillary project to the Framingham Study. A sample of 3529 participants aged 40-80 years had a CT scan performed to assess aortic calcification. 188 individuals were randomly enrolled in this study. The prevalence of intervertebral disc narrowing, facet joint osteoarthritis (FJOA) and DS were evaluated. We used the multiple logistic regressions to evaluate the association between DS as a dependent variable and FJOA, disc narrowing, age, sex and BMI as independent variables. RESULTS: There were 23 individuals (24 spinal segments) affected by DS (15 female, 8 male), mean age 62.0 +/- 6.8 years. In segments with DS, FJOA was observed and rated "severe" at 20 (83.3%) segments, "moderate" at 3 (12.5%) levels, and "mild" at 1 (4.2%) level. Intervertebral disc height was normal in 6 (25.0%), slightly decreased in 6 (25.0%), moderately decreased in 5 (20.8%) and severely decreased in 7 (29.2%) of the segments. Three (12.5%) segments with DS had severe FJOA but no apparent disc degeneration. In 9 (37.5%) segments with DS we found no or mild disc degeneration and severe FJOA. In a multiple regression analysis age, sex and FJOA, but not disc narrowing, showed significant associations with DS. CONCLUSIONS: The results of our study did not support the theory that disc degeneration necessarily precedes vertebral subluxation in DS.

OBJECTIVE: The aim of our study was to evaluate the association between age, sex and body mass index (BMI) and lumbar spine degeneration features evaluated on computed tomography (CT) in a community-based sample. METHODS: This cross-sectional study was an ancillary project to the Framingham Study. A sample of 3529 participants of the Framingham study aged 40-80 had a CT scan performed to assess aortic calcification. 187 individuals were randomly enrolled in this ancillary study. The prevalence of intervertebral disc narrowing, facet joint osteoarthritis (OA), spondylolysis, spondylolisthesis and spinal stenosis were evaluated. To evaluate the association between spinal degeneration features and age, sex and BMI we used chi2 test and logistic regression analyses. RESULTS: 104 men and 83 women, mean age 52.6 +/- 10.8 participated in the study. Statistically significant sexual dimorphism was found in prevalence of spondylolysis (p = 0.015) the male-to-female ratio was 3.3:1; and degenerative spondylolisthesis (p=0.008), the male-to-female ratio was 1:2.8. Prevalence of disc narrowing, facet joint OA, and degenerative spondylolisthesis showed a significant linear trend (p < 0.0001) of association with increasing age. Significantly higher prevalence of facet joint OA was found in the obese group OR (95%CI): 2.8 (1.1-7.2). CONCLUSIONS: Marked differences in the prevalence of spinal degeneration features occur in association with age, sex and obesity. Given the high prevalence of many of these degeneration features these simple demographic factors should be considered when interpreting imaging results reporting these features.

BACKGROUND AND PURPOSE: DTI is a highly sensitive technique, which can detect pathology not otherwise noted with conventional imaging methods. This paper provides the atlas of reliable normative in vivo DTI parameters in the cervical spinal cord and its potential applications toward quantifying pathology. MATERIALS AND METHODS: In our study, we created a reference of normal diffusivities of the cervical spinal cord by using a 2D ss-IMIV-DWEPI technique from 14 healthy volunteers and compared parameters with those in 8 patients with CSM. The 2D ss-IMIV-DWEPI technique was applied in each subject to acquire diffusion-weighted images. FA, lambda( parallel), and lambda( perpendicular) were calculated. A reference of normal DTI indices from 12 regions of interest was created and compared with DTI indices of 8 patients. RESULTS: A map of reference diffusivity values was obtained from healthy controls. We found statistically significant differences in diffusivities between healthy volunteers and patients with CSM with different severities of disease, by using FA, lambda( parallel), and lambda( perpendicular) values. CONCLUSIONS: DTI using 2D ss-IMIV-DWPEI is sensitive to spinal cord pathology. This technique can be used to detect and quantify the degree of pathology within the cervical spinal cord from multiple disease states.

OBJECTIVE: To report diagnosis and treatment of bilateral iliopsoas muscle contracture in a dog with spinous process impingement. STUDY DESIGN: Case report. ANIMALS: German Shepherd dog. METHODS: A dog with chronic progressive lameness, flexion contracture of the coxofemoral joints, severe pain, and decreased femoral reflexes had severe spondylosis bridging the vertebral bodies from L1 to L4 and enlarged dorsal spinous processes from T8 to L6 with impingement and bony proliferation. Ultrasonographic and magnetic resonance imaging (MRI) findings were consistent with fibrosis, mineralization, and atrophy of the iliopsoas muscles bilaterally which was treated by staged tenectomy of the insertions of the iliopsoas muscles. RESULTS: Because of severe perivascular fibrosis, the femoral vessels required ligation. Bilateral iliopsoas muscle tenectomy improved gait and provided pain relief. Histologic findings were consistent with fibrotic myopathy. CONCLUSIONS: Slow progression of severe clinical signs observed bilaterally in this dog differs from previous reports of iliopsoas myopathy. Findings were similar to the fibrotic myopathy of the gracilis or semitendinosus muscles described in dogs. CLINICAL RELEVANCE: Iliopsoas muscle abnormalities should be considered in dogs with limited hip extension and pain. MRI is useful for diagnosing muscle fibrosis. Iliopsoas tenectomy may improve clinical function in dogs with fibrotic myopathy.

BACKGROUND: Autologous iliac crest graft has long been the gold standard graft material used in cervical fusion. However its harvest has significant associated morbidity, including protracted postoperative pain scores at the harvest site. Thus its continued practice warrants scrutiny, particularly now that alternatives are available. Our aims were to assess incidence and nature of complications associated with iliac crest harvest when performed in the setting of Anterior Cervical Decompression (ACD). Also, to perform a comparative analysis of patient satisfaction and quality of life scores after ACD surgeries, when performed with and without iliac graft harvest. METHODS: All patients who underwent consecutive ACD procedures, with and without the use of autologous iliac crest graft, over a 48 month period were included (n = 53). Patients were assessed clinically at a minimum of 12 months postoperatively and administered 2 validated quality of life questionnaires: the SF-36 and Cervical Spine Outcomes Questionnaires (Response rate 96%). Primary composite endpoints included incidence of bone graft donor site morbidity, pain scores, operative duration, and quality of life scores. RESULTS: Patients who underwent iliac graft harvest experienced significant peri-operative donor site specific morbidity, including a high incidence of pain at the iliac crest (90%), iliac wound infection (7%), a jejunal perforation, and longer operative duration (285 minutes vs. 238 minutes, p = 0.026). Longer term follow-up demonstrated protracted postoperative pain at the harvest site and significantly lower mental health scores on both quality of life instruments, for those patients who underwent autologous graft harvest CONCLUSION: ACD with iliac crest graft harvest is associated with significant iliac crest donor site morbidity and lower quality of life at greater than 12 months post operatively. This is now avoidable by using alternatives to autologous bone without compromising clinical or technical outcome.

BACKGROUND: This study was aimed at evaluating whether or not patients with chronic type III acromioclavicular dislocation develop cervical spine pain and degenerative changes more frequently than normal subjects. METHODS: The cervical spine of 34 patients with chronic type III AC dislocation was radiographically evaluated. Osteophytosis presence was registered and the narrowing of the intervertebral disc and cervical lordosis were evaluated. Subjective cervical symptoms were investigated using the Northwick Park Neck Pain Questionnaire (NPQ). One-hundred healthy volunteers were recruited as a control group. RESULTS: The rate and distribution of osteophytosis and narrowed intervertebral disc were similar in both of the groups. Patients with chronic AC dislocation had a lower value of cervical lordosis. NPQ score was 17.3% in patients with AC separation (100% = the worst result) and 2.2% in the control group (p < 0.05). An inverse significant nonparametric correlation was found between the NPQ value and the lordosis degree in the AC dislocation group (p = 0.001) wheras results were not correlated (p = 0.27) in the control group. CONCLUSIONS: Our study shows that chronic type III AC dislocation does not interfere with osteophytes formation or intervertebral disc narrowing, but that it may predispose cervical hypolordosis. The higher average NPQ values were observed in patients with chronic AC dislocation, especially in those that developed cervical hypolordosis.
