The effect of upper cervical or sacroiliac manipulation on hip flexion range of motion.

OBJECTIVES: To compare the effectiveness of an upper cervical manipulation and a manipulation of the sacroiliac joint for increasing hip range of motion. DESIGN: Clinical cohort study. SETTING: Macquarie University Centre for Chiropractic Outpatient Clinic. SAMPLE: Fifty-two randomly chosen university students aged 18 to 34 yr. METHOD: A reliable hand-held dynamometer was used to determine the end point of range of motion before and after the application of a treatment. Three groups of subjects were created: cervical manipulation, sacroiliac manipulation and sham/placebo. Range of motion of the hip in flexion (SLR) was used as the independent variable. RESULTS: The two manipulative treatments resulted in increased flexion range of motion at the hip. Statistical analysis revealed that only the upper cervical manipulation procedure increased hip flexion range of motion significantly. CONCLUSION: The results suggest that manual therapy of the neck may affect hip range of motion in normal adults. Findings such as these may indicate the existence of a link between the cervical spine and the lower extremity.

Lymphocyte profiles in patients with chronic low back pain enrolled in a clinical trial.

OBJECTIVE: Our earlier findings suggest that patients with musculoskeletal complaints have lower numbers and percentages of natural killer (NK) cells than asymptomatic subjects. This study examines patient lymphocyte profiles, as a secondary outcome measure, in a trial of manipulative therapies to treat chronic low back pain (LBP) of mechanical origin. DESIGN: The patients were compared in a randomized controlled trial. Baseline measures were collected at the initial visit; all patients were scheduled for 11 treatments in 14 days. Treatment consisted of either a high-force, high-velocity, low-amplitude manipulation procedure; a low-force, high-velocity, low-amplitude procedure or a series of educational lectures on lower back pain. Posttreatment measures were collected at the final treatment session; follow-up measures were obtained 2 wk later. SETTING: The study was conducted at a chiropractic teaching clinic in the suburban Chicago area. PARTICIPANTS: Individuals over 18 were eligible if they were new patients or repeat patients with a 6 month's hiatus, if the chief complaint was LBP of greater than 50 days' duration, if pain was elicited with palpation over one or more of the facet joints from the spinal levels between L1 and S1 and including the sacroiliac joints, and if there was absence of pain referral or if pain referral was only scleratogenous in nature. Criteria for excluding patients included hard neurologic signs, systemic disease potentially affecting the musculoskeletal system, contraindication to spinal manipulation such as osteoporosis, fracture or other bony pathology, or treatment with medication intended to relieve symptoms associated with their LBP. Eligibility was determined by a staff diagnostic team independent of the attending physician. Three hundred sixty-seven of 1,275 consecutive new patients met the eligibility criteria. Of these, 209 participated. These results are for 201 patients from whom flow cytometric data were obtained. OUTCOME MEASURES: Both absolute numbers and percentages of B-lymphocytes, T-lymphocytes, T-Helper (TH), T-Suppressor (TS) and NK lymphocytes were determined. Blood samples were collected at the same time that the primary outcome measures were obtained. Cells were stained with two-color monoclonal antibodies directed against specific cell surface antigens, and each lymphocyte subpopulation was quantified directly from lysed whole blood with a Coulter Epics Profile II flow cytometer. RESULTS: Thirty-five patients dropped out before the follow-up visit and technical problems resulted in the loss of data from 17 more and the exclusion of some subpopulation data. In all, 148 cases were analyzed for B cells, 146 for TH, TS and NK cells and 138 for cells that carried both the NK and TS marker. A one-way analysis of variance revealed no significant differences in the lymphocyte profiles at baseline among the three groups. All subpopulation baseline values were within reported reference ranges for normal adult populations. However, the percentage of NK cells (9.1%) was below the published minimum critical value. A repeated measures analysis of variance was used to determine whether treatment effects changed over time, that is, treatment-time interaction. The cell types for which the interaction tests were at or near statistical significance were: TH cells (p = .0208), total T cell percent (p = .0928) and absolute total T cells (p = .0908). Interaction tests for differences in either percent or absolute counts of B cells, TS cells, or NK cells were not statistically significant. CONCLUSIONS: This is the first report of lymphocyte profiles in patients with diagnosed chronic LBP. Our finding of a lower percentage of NK cells in these patients confirms our earlier finding that patients with musculoskeletal problems have a lower percentage of NK cells than do asymptomatic subjects. However, manipulative therapy was not shown to have a clinically significant effect on either the absolute n

Osteoarticular brucellosis: results of bone scintigraphy in 140 patients.

One hundred forty patients with proved brucellosis and clinical evidence of bone and joint involvement were evaluated prospectively by 99mTc-methylene diphosphonate scintigraphy to assess the frequency of positive findings. To evaluate the radiographic abnormalities associated with positive scintigraphy, all areas of the skeleton that showed abnormal uptake were studied further by plain radiography. High-resolution CT was performed in all patients who had spinal lesions. Ninety-six patients (69%) had abnormal radionuclide uptake in 57 extraspinal and 101 spinal sites. Uptake was increased in 53 joints and three long bones and decreased in one joint. The knee was the most frequently involved site; the second was the sacroiliac joint. Radiographic and high-resolution CT changes were seen in only 12 (21%) of 57 extraspinal sites. In the spine, the abnormal scintigrams showed either focal increased uptake in affected vertebral bodies (detected mostly on the anterior view and seen in 51 lower thoracic and lumbar vertebrae in 24 patients) or diffuse increased uptake in adjacent vertebrae (detected in anterior and posterior views and seen in 50 different disk levels in 38 patients). Radiographic and high-resolution CT changes were seen at all scintigraphically positive sites. We conclude that bone scintigraphy is a useful method for screening patients with osteoarticular brucellosis. It is more sensitive than radiography in assessing involvement of the extraspinal skeleton and in the spine, it allows accurate localization of affected areas.

Joint manifestations in Behçet's disease. A review of 340 cases.

OBJECTIVES: To gain additional knowledge on the joint manifestations of Behçet's disease, with special attention to unusual forms. PATIENTS AND METHODS: Retrospective review of 340 cases with joint manifestations identified among 601 cases of Behçet's disease seen over a 15-year period. All the patients met International Study Group for Behçet's disease criteria. Radiographs of all joints with arthritis were obtained. Starting ten years ago, a radiograph of the sacroiliac joint was taken routinely. RESULTS: Joint manifestations were present in more than half the patients (56.57%) and were inaugural in 18.23% of cases. The knees and ankles were the joints most commonly affected. Monoarthritis and oligoarthritis were seen in 16.17% and 11.76% of cases, respectively and polyarthritis involving the large limb joints and the small joints of the hands and feet in 17.05% of cases. Unusual forms included polyarthritis with deformities and/or destruction (n: 8, including two patients who also met criteria for rheumatoid arthritis), pseudogout (n: 5), popliteal cyst (n: 3, including one case imitating deep vein thrombosis), myositis (n: 1), spondylarthropathy (n: 5), and Sjögren's syndrome (n: 2). Children were more likely than adults to have joint manifestations (73.68%) and polyarthritis (35.7%). CONCLUSION: Joint manifestations are common in Behçet's disease. Their unusual forms deserve to be known since they can raise diagnostic problems when they are inaugural.

Human immunodeficiency virus related reactive arthritis in Zambia.

OBJECTIVE: To characterize the clinical, radiological, and diagnostic features of reactive arthritis (ReA) in indigenous Black Zambians with human immunodeficiency virus (HIV) infection. METHODS: Consecutive patients attending an arthritis clinic over a 5-year period were studied prospectively. Those who satisfied diagnostic criteria for ReA were analyzed. RESULTS: In total, 170 patients satisfied the ESSG criteria for ReA; 71 (45 men, 26 women) had one or more extraarticular manifestations; 30% had enteroreactive and 14% uroreactive disease. Only 59% of patients had the diagnostic features of ReA at presentation. The initial diagnosis was undifferentiated spondyloarthropathy (uSpa) in 20%, other ReA in 14%, and "arthritis alone" in 7%. Of 65 (42 men, 23 women) patients tested, 94% were HIV-positive (91% men, 100% women). In those with HIV, the arthritis was predominantly polyarticular, lower limb-predominant, and progressive; 58% of 33 with persistent disease had erosions of foot and/or hand joints (average disease duration, 24.4 mo); 6 of 10 showed early radiological spine or sacroiliac joint changes (average duration 47.7 mo). Anterior uveitis occurred in 33% of patients, while keratoderma blenorrhagicum and stomatitis occurred in 14.3% and 9.5%, respectively, of patients with enteroreactive ReA. Uroreactive ReA was more common in women. There were no significant differences in the clinical, diagnostic, or radiographic features between men and women or between those with or without a known preceding trigger. CONCLUSION: HIV associated ReA in Black Zambians frequently follows an accelerated course with a strong tendency to relapse, develop early erosions and joint deformity, and become chronic. The clinical, diagnostic, and radiographic features are indistinguishable from those described in the conventional (HLA-B27 related) disease, although our HIV-positive patients have a high overall frequency of uveitis, keratoderma, and onycholysis.

Spondyloarthropathy is underestimated in inflammatory bowel disease: prevalence and HLA association.

OBJECTIVE: To determine the overall prevalence of spondyloarthropathy (SpA) among patients with inflammatory bowel disease (IBD) [Crohn's disease (CD) and ulcerative colitis (UC)]. METHODS: One hundred three consecutive patients with IBD from a gastroenterology unit were questioned and examined for SpA symptoms. Patients previously diagnosed with SpA were excluded. All patients were questioned and examined for SpA symptoms such as inflammatory back pain, joint swelling, enthesitis, and psoriasis or a specific family history. Radiographs were taken of all sacroiliac joints. HLA loci A, B, C, and DR were determined in all patients. RESULTS: Thirty-nine percent of the patients with IBD had clinical articular manifestations: 30% had inflammatory back pain, 10% had synovitis, and 7% had a peripheral enthesopathy. The majority (90%) of patients with rheumatic complaints fulfilled the classification criteria for SpA and 10% fulfilled the criteria for ankylosing spondylitis. Asymptomatic sacroiliitis was found in an additional 18% of the patients. Moreover, sacroiliitis, symptomatic or asymptomatic, was related to the disease duration. HLA-B27 conferred an additional risk for inflammatory low back pain in patients with IBD. CONCLUSION: Articular involvement in IBD can be classified as SpA. The appearance of SpA occurs irrespective of the extent of the bowel disease. Moreover, asymptomatic sacroiliac involvement is a common manifestation in IBD and it is related to disease duration, suggesting evidence for a related pathogenic mechanism.

Open label trial of anakinra in active ankylosing spondylitis over 24 weeks.

OBJECTIVE: To examine the therapeutic effect of the interleukin 1 (IL1) receptor antagonist anakinra in ankylosing spondylitis in an open label trial. METHODS: Anakinra (100 mg) was given subcutaneously daily over 24 weeks to 20 NSAID refractory patients with ankylosing spondylitis. Thirteen completed the study. Clinical outcome assessments included disease activity, function, metrology, patients' and physicians' global assessment, peripheral joint assessment, quality of life, and C reactive protein. Dynamic magnetic resonance imaging (MRI) of sacroiliac joints or spine, using gadolinium DTPA as contrast agent, was done before treatment in 15/20 patients, and in 10 patients at study end. The primary end point was the Bath ankylosing spondylitis disease activity index (BASDAI) and ASAS (assessments in ankylosing spondylitis) short term response after six months. RESULTS: Using an intention to treat analysis, an ASAS 20% response (ASAS 20) was achieved in five patients, ASAS 40 in four, and ASAS 70 in two after 24 weeks. There was no change in mean C reactive protein (22.3 v 33.1 mg/l) or in MRI score. The drug was well tolerated. Injection site reaction was the commonest adverse event. CONCLUSIONS: In this open study, anakinra improved spinal symptoms in only a small subgroup of patients with active ankylosing spondylitis.

Epidemiology of osteoarthritis: Zoetermeer survey. Comparison of radiological osteoarthritis in a Dutch population with that in 10 other populations.

The prevalence of mild and severe radiological osteoarthritis was investigated in a random sample of 6585 inhabitants of a Dutch village. Radiographs were graded 0-4 according to the criteria described by Kellgren and Lawrence. The prevalence of radiological osteoarthritis increased strongly with age and was highest for cervical spine (peak: men 84.8%, women 84.3%), lumbar spine (peak: 71.9%, women 67.3%), and distal interphalangeal joints of the hands (peak: men 64.4%, women 76%). Prevalence did not exceed 10% in sacroiliac joints, lateral carpometacarpal joints, and tarsometatarsal joints. Severe radiological osteoarthritis (grade 3 or grade 4) was uncommon under age 45; in elderly persons the prevalence of severe radiological osteoarthritis did not exceed 20% except for the cervical and lumbar spine, distal interphalangeal joints of the hands and, in women only, metacarpophalangeal joints, first carpometacarpal joints, first metatarsophalangeal joints, and knees. Overall, differences between men and women were small except for hips and knees; however, severe radiological osteoarthritis was found in a higher proportion in most of the joints in women. Our data were compared with data from similar population surveys. The slope between joint involvement and age was strikingly constant for most of the joints. Differences between populations were mainly differences in level. These differences of prevalence of radiological osteoarthritis may be attributed to interobserver differences--that is, different criteria used to establish radiological osteoarthritis, in addition to genetic or environmental factors, or both.

Rigid spine syndrome. Two case-reports.

UNLABELLED: Rigid spine syndrome is characterized by massive spinal rigidity, usually most marked in the cervical region. Stiffness of the peripheral joints is sometimes present. We report two cases. Patient 1 was a 12-year-old boy diagnosed at three years of age with Duchenne's muscular dystrophy because of delayed onset of walking. Contracture of the Achilles tendons, flexion contracture of the elbows, and loss of motion of the cervical spine were the main findings during the current evaluation. Radiographs of the affected joints were normal. An electrocardiogram showed an incomplete left bundle branch block. Muscle enzyme activities were moderately elevated. A myopathic pattern was seen on the electromyogram. A muscle biopsy showed muscle fiber atrophy with peri- and endomysial fibrosis. Patient 2 was a 39-year-old man with a five-year history of isolated rigidity of the cervical spine thought to be due to a spondylarthropathy. Extension was the only movement possible at the cervical spine. The peripheral joints showed no motion range limitation. Findings were normal from radiographs of the spine and sacroiliac joints, an erythrocyte sedimentation rate determination, an electromyogram, and muscle enzyme activity assays. A muscle biopsy showed muscle fiber atrophy with peri- and endomysial fibrosis. DISCUSSION: Rigid spine syndrome is rare in rheumatological practice and can simulate a number of other muscle and joint diseases. Peri- and endomysial fibrosis may be strongly suggestive, although nonpathognomonic. Involvement of the heart governs the prognosis.

[Ankylosing spondylitis in women: comparison of scintigraphic results with clinical and roentgenologic findings].

Since ankylosing spondylitis (S.a.) tends to be milder and less progressive in women than in men, there are great difficulties in diagnosing S.a. in female patients. The role of scintiscanning for investigation of S.a. in women is discussed by few examiners only, especially there are no investigations of quantitative sacroiliac scintigraphy in large groups of female patients. Quantitative sacroiliac scintigraphy was performed in 19 female patients with S.a. and in 30 control subjects. The sacroiliac/sacrum ratio (Index ISG/sacrum) was calculated. Significantly increased uptakes were found in the patient group compared with the controls. Especially in the early periods of S.a. the activity index was highest. When history and physical examination lead to a suspicion of S.a. and there is no verification by roentgenographic studies, sacroiliac joint scintigraphy is indicated. If clinical and laboratory findings are respected in each patient, quantitative sacroiliac scintigraphy is useful for the early diagnosis of S.a. in female patients.

Subclinical CT abnormalities in the lumbosacral spine of older large-breed dogs.

Computed tomography (CT) of the L5-S3 vertebral levels was performed in six, large-breed dogs presented for problems unrelated to the lumbosacral spine. All dogs were asymptomatic for lumbosacral stenosis on neurologic examination. Breeds included German Shepherd, Golden Retriever, Boxermix and Belgian Malinois. Ages ranged from 5-12 years. Five out of six dogs exhibited CT abnormalities. Among the 18 disc levels examined, the most common findings were idiopathic stenosis, loss of vertebral canal epidural fat, and nerve tissue displacement. Less common abnormalities were vertebral canal or foraminal bone proliferation, loss of intervertebral foramen fat, vertebral canal disc bulging, degenerative articular process joint disease, transitional vertebra, dural ossification, foraminal disc bulging, Schmorl's nodes, calcified extruded disc fragment, and sacroiliac joint osteophytes. Vertebral subluxation was absent in all dogs. Findings indicate that some lumbosacral CT abnormalities may be clinically insignificant, especially in older dogs.

Peripheral pyogenic arthritis. A study of one hundred seventy-nine cases.

A retrospective medical record-based study of cases of peripheral pyogenic arthritis diagnosed in a rheumatology department between 1966 and 1993 was conducted. Of the 197 cases, 179 were evaluable. Pyogenic arthritis accounted for 0.68% of admissions and 30.3% of bone and joint infections during the study period. Incidence rose gradually from 2.2 new cases per year between 1966 and 1970 up to 6 to 10 new cases per year since 1991. In 88% of cases a single joint was involved, with the most commonly affected sites being the knee (32.5%), hip (22.2%), shoulder (12%) and sacroiliac joint (11.4%). Of the 22 patients with polyarticular arthritis, 19 had involvement of two joints. A portal of entry was identified in 53% of cases. Of the 13% of iatrogenic cases, half occurred after a local corticosteroid injection. The pathogen was identified in 65% of cases. Staphylococcus aureus was the most common organism (56%) followed by streptococci (9.5%) and E. coli (7%). Only three patients had gonococcal arthritis. Mean duration of therapy was four months. Although complications were exceedingly rare, three patients died and three others developed septic shock. Our data suggest that the presentation of pyogenic arthritis has remained essentially unchanged. In particular, we found no increase in iatrogenic forms, in contrast to recent experience with vertebral osteomyelitis.

Radiologic features of gout.

Gout is a common rheumatologic disease characterized by the deposition of monosodium urate crystals in tissue from supersaturated extracellular fluid. The deposition of crystals in the joints and periarticular soft tissue can lead to arthritis and bone destruction. The radiologic features of gout include swelling of soft tissues, tophi, normal mineralization, preservation of joint space until the later stages of disease, "punched-out" erosions with overhanging edge of cortex and sclerotic borders, and an asymmetric polyarticular distribution. The lower-extremity joints are most often affected, but the small joints of the hands, wrists and elbows may also be involved. Gout rarely occurs in the shoulders, hips, sacroiliac joints or spine.

Erosive arthritis of the costovertebral joint in seronegative spondyloarthropathy.

A 50-year-old male presented with polyarthritis and pain of the right costovertebral angle in the cervicothoracic area. Radiological findings in a sacroiliac joint, the presence of a syndesmophyte, the HLA B-27 phenotype and negative serological studies prompted the diagnosis of HLA-B27 related seronegative spondyloarthropathy. Conventional and computerized tomograms disclosed an erosive arthritis of the 1st right costovertebral joint that was responsible for the pain in the costovertebral angle. We are unaware of previous CT scan documentation of such lesions.

Parturition-induced pelvic dislocation: a report of four cases.

OBJECTIVE: To describe our experience with four cases of severe pelvic dislocation associated with difficult parturition. DESIGN: Retrospective case series. PATIENTS: Four patients, each with rupture of the symphysis pubis and sacroiliac joints during labor. All injuries were associated with significant initial pain and disability. All developed persistent symptoms related to the sacroiliac disruption. INTERVENTIONS: The three patients who had presented acutely were freated with closed reduction and application of a pelvic binder. Two underwent closed reduction of their pelvic dislocation while anesthetized with a general anesthetic. One patient (N.A.), who presented late, had not been treated with a binder. RESULTS: All four patients had persistent posterior pelvic (sacroiliac) pain. In two patients a postpartum neuropathy persisted. CONCLUSIONS: Severe pelvic dislocations are rare during labor, with conservative treatment reported to be successful in most cases. The persistence of symptoms in our patients emphasizes the need for careful examination and follow-up of these rare injuries. Because the outcome in our patients was poor and results in the literature are equivocal, we suggest the consideration of an operative approach to treatment in patients with symphyseal diastasis of > 4.0 cm.

Sacroiliac screw fixation for tile B fractures.

BACKGROUND: The purpose of this comparative cadaveric study was to investigate whether the stability of partially unstable pelvic fractures can be improved by combining plate fixation of the symphysis with a posterior sacroiliac screw. METHODS: In six specimens, a Tile B1 (open-book) pelvic fracture was created. We compared the intact situation with isolated anterior plate fixation and plate with sacroiliac screw fixation. Using a three-dimensional video system, we measured the translation and rotation stiffness of the fixations and the load to failure. RESULTS: Neither absolute displacements at the os pubis or at the sacroiliac joint nor stiffness of the ilium with respect to the sacrum were significantly different for the techniques with or without sacroiliac screw or the intact situation. Load to failure was reached in only one of the six cases. In all other cases, the fixation of the pelvis to the frame failed before failure of the fixation itself. In these cases, a load of approximately 1,000 N or more could be applied. CONCLUSION: The addition of a sacroiliac screw in a Tile B1 fracture does not provide significant additional stability. Although cyclic loading was not tested, in these experiments forces could be applied that were similar to full body weight. Clinical experiments into direct postoperative weight bearing are recommended to examine the clinical situation.
