Iliac hyperdense line: a new radiographic sign of gluteal muscle contracture.

BACKGROUND: A hyperdense line on the ilium that runs roughly parallel to the sacroiliac joint (we called it "iliac hyperdense line sign") was frequently observed on pelvic radiographs of patients with gluteal muscle contracture (GMC). A literature search revealed no description of this sign. OBJECTIVE: To determine the relationship between the iliac hyperdense line sign and GMC and to explore how this sign is formed. MATERIALS AND METHODS: Pelvic plain films of 103 cases of GMC and those of 200 control individuals were reviewed for the presence or absence of the iliac hyperdense line sign. Pelvic CT scans in 8 of 103 cases and 13 of 200 controls were analyzed with relation to the plain films. RESULTS: The iliac hyperdense line sign was visualized in 85 of 103 (82.5%) cases of GMC and none of the 200 controls. In the GMC group, pelvic CT scans showed a deformity of the posterior ilium. The lateral cortex of the posterior ilium took on a partly or completely anteroposterior course, while in the control group the course appeared as an oblique orientation from posteromedial to anterolateral. CONCLUSION: The iliac hyperdense line on pelvic plain film can be used as a radiographic sign to suggest a diagnosis of GMC. This sign might be a result of the long and persistent pulling effect of the contracted gluteus maximus muscle, which deforms the lateral cortex of the posterior ilium from an oblique course to an anteroposterior course tangential to the X-ray beam.

Anastomoses between the spermatic and visceral veins: a retrospective study of 500 consecutive patients.

BACKGROUND: Do visceral-spermatic vein shunts have any clinical impact on sclerotherapy of varicoceles? METHODS: The spermatic venograms of 500 consecutive patients were retrospectively reviewed to classify visceral-spermatic communications. Men with an average age of 27.8 years (range 11-65 years old) underwent sclerotherapy of a varicocele. Of the 500 men, 445 were referred for oligoasthenospermia (89%), 45 for pain (9%), and 10 for prevention of infertility (2%). After bilateral catheterization, percutaneous sclerosis was performed below the upper third of the sacroiliac joint. RESULTS: Three hundred forty patients (68%) had left-sided, 10 (2%) had right-sided, and 150 (30%) had bilateral varicoceles. Left side: Of 46 (9.4%) anastomoses, one (0.2%) communicated with the splenic vein and 45 (9.2%) with the inferior mesenteric vein of which 25 (5.1%) were a colic trunk with a competent valve, 15 (3.1%) were venules, and five (1%) were a single or double anastomosis. Right side: Of 48 (29.6%) anastomoses to the superior mesenteric vein, 34 (21%) were venules, 12 (7.4%) were a colic trunk with a competent valve, and two (1.2%) were a single or double vein. Our varicocele recurrence rate was only 1.2%. CONCLUSION: Visceral-spermatic vein communications are classified by number, morphology, and site. Percutaneous sclerotherapy could be optimized when performed caudally to these communications.

Anatomical study of the blood supply of the coxal bone: radiological and clinical application.

The aim of this work was to study the arterial blood supply of the coxal bone in order to optimize radiological embolization and to minimize the risk of postoperative osteonecrosis. Ten fresh cadavers were dissected after intra-arterial injection of colored resin. All the collateral vessels running to this bone were described and counted. On 25 dry bones, the vascular foramina were measured with the aid of a millimetric gauge and a vascular map was created. The posterior part of the ilium appears to be twice as well vascularized as the anterior part. Fractures of the posterior arch of the pelvis are theoretically more hemorrhagic. The presence of the iliolumbar artery in contact with the sacroiliac joint increases the risk with open book or shearing fractures. The artery of the ischium, a collateral of the pudendal artery, supplies the posterior and lateral parts of the acetabulum and the artery of the roof of the acetabulum, its superior and lateral parts. The branches of the anterior and posterior divisions of the obturator artery supply the superior part of the surroundings of the obturator foramen and the antero-inferior and postero-inferior parts of the acetabulum. The Kocher approach may injure the artery of the ischium. Letournel's extended lateral approach and Mears' triradiate approach may injure the artery of the ischium and the artery of the roof of the acetabulum. The risk of osteonecrosis appears to be theoretically increased if one adds an endopelvic approach. The anterior approach to the acetabulum appears to be that which theoretically leads to the least devascularization.

Cervical involvement in juvenile-onset ankylosing spondylitis with bone scintigraphy.

Juvenile-onset ankylosing spondylitis is an unusual disorder which can present with either peripheral arthritis or more classic hip girdle and back symptoms. A 12-year-old child with this disease was admitted with walking disorder, cervical pain, restricted cervical motion, and right ankle swelling. Diffusely increased accumulation of radioactivity in the cervical spine, focally increased accumulation in bilateral sacroiliac joints, and diminished irregular uptake in thoracal spine were detected on technetium 99m methylene diphosphonate bone scintigraphy. As a result, this imaging technique may give important information for diagnosis and differential diagnosis in juvenile chronic arthritis.

A case of osteomalacia mimicking ankylosing spondylitis.

A 39-year-old woman presented with symptoms of pain in the lumbar region and lower extremities. Physical findings included restricted movement of the lumbar spine, sacroiliac joint tenderness, positive Schober's test (10-12.5 cm), and bilaterally positive Mennel and Fabere tests. Although these symptoms and findings were suggestive of ankylosing spondylitis, osteomalacia was diagnosed with the appearance of multiple pseudofractures in her pelvic X-ray and laboratory abnormalities. All her symptoms and signs resolved in 6 months with vitamin D and calcium treatment.

Hip pain in adults: MR imaging appearance of common causes.

To determine the exact origin of hip pain can be challenging. Symptoms apparently originating from the hip may arise from the pelvis, the sacroiliac joint, the lumbar spine, periarticular structures such as muscles and bursae, or from unexpected sites such as the abdominal wall, the genitourinary tract, or the retroperitoneal space. This article reviews the differential diagnosis of hip pain arising from the hip and surrounding structures and the role of different imaging methods with emphasis on magnetic resonance imaging where most recent advances have occurred.

Acetabular pneumatocyst containing air-fluid level.

The presence of intraosseous gas most commonly occurs in osteomyelitis, vacuum phenomenon, and postsurgery or posttraumatic states. Several cases of subchondral gas-filled lesions, called pneumatocysts, have also been described in the sacroiliac joint and clavicle, none of them with intralesional air-fluid level. These pneumatocysts are innocuous lesions of uncertain origin. We describe one case of acetabular pneumatocyst containing air-fluid level in a 62-year-old man with long-standing ankylosing spondylitis involving hip joint. To our knowledge, this is the first reported case of a pneumatocyst in an acetabular location containing air-fluid level.

[Outcome parameters in ankylosing spondylitis].

Ankylosing spondylitis (AS) is a frequent inflammatory rheumatic disease and prototype of the Spondyloarthitides (SpA). During the last years outcome parameters have been developed to evaluate different aspects of the disease. Among these are the Bath AS Disease Activity Index (BASDAI), Bath AS Functional Index (BASFI), Bath AS Metrology Index (BASMI), numeric rating scales for general pain, night pain, patients and physicians global assessment, as well as questionnaires to evaluate quality of life as the short Form (SF)- 36, Euroquol 5 Dimensions (EQ-5D), or the AS specific the ASQuol. These outcome parameters are the basis to conduct clinical trials. The ASessements in AS (ASAS) improvement criteria were developed to evaluate the short term efficacy of Non-Steroidal Antirheumatic Drugs (NSAIDs) and adjusted for the measurement of the high efficacy of the TNF-alpha blocking agents. To examine the x-rays of sacroiliac joints (SIG), the radiological criteria as part of the modified New York criteria are mostly used. For the x-rays of the spine the Bath AS Radiology Index (BASRI) is valuable in daily practice, but the modified Stokes AS Spine Score (mSASSS) is more sensitive for clinical trials. To examine Magnetic Resonance Images (MRI) of SIG and spine also scores are currently developed. Altogether, using the new outcome parameters it was possible to demonstrate the strikingly high efficacy of theTNF-alpha blocking agents. However, it could also be shown that conventional disease modifying antirheumatic drugs (DMARDs) are not effective in the treatment of the axial forms of SpA.

[Imaging in ankylosing spondylitis].

In addition to the typical clinical symptoms, conventional x-rays and magnetic resonance imaging (MRI) are important for the diagnosis and management of ankylosing spondylitis (AS). While radiography is mainly useful for detecting chronic structural changes, MRI is, in addition, able to detect active inflammation. The detection of structural changes in the sacroiliac joints and, in part, the spine, remains the gold standard for the diagnosis of AS. The detection of active sacroiliitis or spondylitis in early disease stages is only possible using MR techniques such as STIR and T1 post-gadolinium sequences. Lateral radiographs of the spine are useful for detecting shiny corners and the characteristic syndesmophytes and ankylosis. The modified Stoke Anklyosing Spondylitis Spine Score (SASSS) is the best scoring method for quantifying such changes, allthough only the cervical and the lumber spine are evaluated with this method. MRI changes can also be quantified. New scoring methods are sensitive to change only 3 months after initiation of therapy with anti-TNF agents.

[Spondylarthritides].

Ankylosing spondylitis (AS) is the major subtype and a major outcome of an interrelated group of rheumatic diseases now named as spondyloarthritides (SpA). The most important clinical features of this group are inflammatory back pain (IBP), asymmetric peripheral oligoarthritis, predominantly of the lower limbs, and enthesitis. Established classification criteria for AS and SpA are known to perform less well in early disease stages. This partly contributes to the delay in diagnosis, mainly due the high frequency of back pain in the population. The methods for making an early diagnosis have recently improved. The major factors involved in this improvement are HLA B27 and magnetic resonance imaging of the sacroiliac joints, but also of the spine. Conventional radiography, however, is still the gold standard. International recommendations for the management of AS have recently been published. Conventional medical treatment is based mainly on the use of non-steroidal anti-inflammatory agents (NSAIDs); patients with peripheral arthritis may be treated with sulfasalazine. Patients with persistently active disease benefit from therapy with anti-TNF agents. Physiotherapy is of major importance in the general approach to patients with SpA, especially with AS.

The pelvic external fixation: the mid-term results of 41 patients treated with a newly designed fixator.

The purpose of this study was to evaluate the clinical and radiological results of unstable pelvic fractures treated with a new external fixation device. Between May 1992 and May 1998, 43 patients with unstable pelvic fractures were treated with a new anterior pelvic external fixator. Two died, and therefore 41 patients' results were evaluated. There were 29 men and 12 women, and their average age was 34 years (range 12-70 years). Traffic accidents accounted for 34 injuries. Three patients fell from a height, 3 were injured in industrial accidents, and 1 was hit by a train. According to the Tile classification, there were 24 type B pelvic injuries and 17 type C. Associated injuries were observed in 21 patients. A considerable reduction of the pelvic pain was noted after application of the fixator in all patients. Excessive blood transfusion was not required in any patient. The average follow-up was 24 months (range 12-50 months). Clinical results at final evaluation were good according to the criteria of Matta and Saucedo in 34 patients and poor in 7. In conclusion, the new pelvic external fixator is effective, safe, and easy to apply in the treatment of unstable pelvic fractures. The fixator can be used alone in patients with type B pelvic injuries such as open book and lateral compression. However, it does not provide sufficient stability for severely displaced type C injuries when applied alone. Nevertheless, it may be helpful for fixing type C injuries like a posterior iliac fracture without dislocation of the sacroiliac joint.

The effect of single-level, total disc arthroplasty on sagittal balance parameters: a prospective study.

A prospective radiographic study of the influence of total disc replacement on spinal sagittal balance. The goal of this study was to prospectively determine the effect of a single-level, total disc replacement on the sagittal balance of the spine, especially on sacral tilt (ST), pelvic tilt (PT), and lumbar lordosis. It has been shown that lumbar fusion may deleteriously alter the sagittal balance of the spine, including a decrease in the ST and lumbar lordosis. Clinically, postfusion pain has been shown to be significantly related to a decreased ST, increased PT, and decreased lumbar lordosis, independent of other factors such as pseudoarthrosis. To our knowledge, the influence of total disc replacement on spinal sagittal balance has not yet been reported in the literature. This is a prospective study of 35 patients who received a single level disc replacement using the Maverick Total Disc Arthroplasty system (Medtronic Sofamor Danek, Memphis, Tennessee) by a single surgeon at one institution from March 2002 to September 2003. The preoperative and postoperative radiographic evaluation included standing anteroposterior and lateral full spine films that included the femoral heads. The parameters studied were ST, PT, global and segmental lordosis, and global kyphosis. The average age of the 35 patients studied was 44.3 years (range 35-57). There were 18 females and 17 males. The disc arthroplasty was performed at the L4-L5 level in 19 patients and at the L5-S1 level in 16 patients. The average follow-up was 14 months (range 6-22 months). The preoperative values of global lordosis, ST, and PT were 51.5 degrees , 37.8 degrees , 16.9 degrees and, at last follow-up, they were 51.4 degrees , 37.4 degrees , and 17.5 degrees , respectively. These changes were not significantly different. When the groups were separated according to the level operated, there was still no statistical difference with regard to the overall lordosis, ST, PT or kyphosis from pre- to postoperative period or when the two groups were compared with each other. The level above the prosthesis has always significantly less lordosis. In the present study with use of a motion-preserving Maverick prosthesis, it appears that the patient is able to maintain the preoperative sagittal balance. The prosthesis has enough freedom of motion to allow the patient to maintain the natural sagittal and spinopelvic balance needed to prevent potential undue stress on the muscles and the sacroiliac joint. Although the number of patients is small, this is the first study to our knowledge that evaluates the sagittal balance after motion-preserving total disc arthroplasty.

Sciatica in the female patient: anatomical considerations, aetiology and review of the literature.

The principal author was confronted few years ago with the case of a 38-year-old woman with a 5-month history of ill-defined L5 sciatic pain that was referred to an orthopaedic department for investigation and eventual surgical treatment for what was suspected to be herniated disc-related sciatica. Removal of her enlarged uterus found unexpectedly close to the sacroiliac joint upon lumbar MRI abolished her symptoms. Review of the literature showed that the lumbosacral trunk is vulnerable to pressure from any abdominal mass originating from the uterus and the ovaries. Physiological processes in the female patient and gynaecological diseases may be the source of sciatica, often not readily searched for, leading to fruitless investigations and surgical treatments. The aim of the paper is to highlight gynaecological and obstetrical causes of sciatica and sciatica-like symptoms. To prevent unproductive expenses and morbidity, a thorough gynaecological examination should be done even though neurological examination may be suggestive of a herniated intervertebral disc, and the cyclic pattern of pain related to menses should be routinely asked for.

Adaptation of the Bath Ankylosing Spondylitis Functional Index to the Turkish population, its reliability and validity: functional assessment in AS.

The aim of this study was to adapt the Bath Ankylosing Spondylitis Functional Index (BASFI) to the Turkish population and investigate the reliability and the validity of the Turkish version. Seventy-six patients with ankylosing spondylitis (AS) were included in the study. The functional status of the patients was assessed by using the adapted Turkish version of the BASFI twice, at recruitment and 24 h later. For validity analysis, patients were also assessed by the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) evaluating disease activity, the Bath Ankylosing Spondylitis Global Score (BAS-G) indicating effect of the disease on patient's well-being, physician's assessment of the disease activity and pain intensity. Spinal mobility was assessed by the Bath Ankylosing Spondylitis Metrology Index (BASMI). Erythrocyte sedimentation rate (ESR) and serum C-reactive protein (CRP) levels of the patients were also recorded. The lumbar region and the sacroiliac joints were assessed by Stoke Ankylosing Spondylitis Spine Score (SASSS) and the hip joints were assessed by Bath Ankylosing Spondylitis Radiology Index hip (BASRI-h). The internal consistency was 0.89 (Cronbach's alpha), which showed a high reliability for the Turkish version of the BASFI. Test-retest reliability was good, with a high intraclass correlation coefficient between the two time points (ICC=0.93). Significant correlations were detected between the BASFI and the BASDAI, BAS-G, doctor's global assessment, and general pain intensity (r=0.62, p<0.001; r=0.47, p<0.001; r=0.55, p<0.001; r=0.47, p<0.001, respectively). The adaptation of the BASFI to the Turkish population was successful and it was found to be reliable and valid among Turkish patients. Thus, studies using the Turkish BASFI can be compared with international studies.

Comparison of serum IL-1 beta, sIL-2R, IL-6, and TNF-alpha levels with disease activity parameters in ankylosing spondylitis.

Ankylosing spondylitis (AS) is a chronic, inflammatory, rheumatological disease affecting primarily the sacroiliac joint and vertebral column, with an etiology that remains obscure. Cytokines are soluble proteins that have specific roles in inflammatory response, arranging the interaction between cells of the immune system both in natural and specific immune reactions. This study was planned to evaluate the relation between the level of cytokines and the clinical and laboratory findings of patients with AS compared to healthy subjects. In this study, we demonstrated increased serum levels of soluble interleukin-2 receptor (sIL-2R), Interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-alpha) in patients with AS compared with healthy subjects. Only IL-1 beta levels were not increased in AS patients. We found a correlation between C-reactive protein and IL-6 levels and between erythrocyte sedimentation rate and sIL-2R, IL-6 and TNF-alpha levels. Only the sIL-2R level was correlated with Bath AS Metrology Index and Bath AS Functional Index. We suggest that sIL-2R, IL-6, and TNF-alpha may have a role in the pathogenesis of AS and that their serum levels can be used as disease activity parameters and tools for diagnosis.

Reiter's syndrome during intravesical BCG therapy for bladder carcinoma.

A 50-year-old male with superficial bladder carcinoma developed fever, conjunctivitis, cystitis, and arthritis of the ankles and metatarsophalangeal and sacroiliac joints after the fourth course of intravesical Bacillus Calmette-Guerin (BCG) therapy. Reiter's syndrome in the context of BCG therapy was diagnosed, and intravesical immunotherapy was discontinued. Treatment with indomethacin was started with partial response, while a significant clinical improvement was noted when prednisolone 30 mg daily was started. One month later, the patient was on full clinical and laboratory remission, and steroid treatment was gradually tapered. Clinicians should be aware of this rare complication of BCG therapy because early diagnosis may lead to early management.
