Reliability of sacroiliac joint laxity measurement with Doppler imaging of vibrations.

We developed a noninvasive technique, referred to as Doppler imaging of vibrations (DIV), to measure laxity of the sacroiliac joint (SIJ). The purpose of this study was to examine the reliability of SIJ laxity measurements. A total of 10 healthy women (mean 29.6 +/- 6 years old) participated in the study. At both sides, SIJ laxity was measured with DIV in threshold units (TU). Reliability and measurement error were assessed from repeated measurements by five testers on two occasions as well as by one experienced tester. Intraclass correlation coefficients ranged from 0.53 to 0.80 for all five testers, and from 0.75 to 0.89 for the one experienced tester. Only changes larger than 1.94 to 3.60 TU (any tester) or 1.45 to 2.38 TU (experienced tester) could be confidently detected. DIV is a reliable technique for SIJ laxity measurements in healthy subjects, when performed by an experienced tester.

Radiographic changes in the sacroiliac joints in familial Mediterranean fever.

In a series of 43 patients with familial Mediterranean fever, six were found to have radiographic changes in the sacroiliac joints consisting of loss of normal cortical definition, sclerosis on both sides of the joint with or without erosions, and fusion. These changes were noted despite the absence of clinically symptomatic joint disease. The explanation for these findings is unknown.

Experimental study of the sacroiliac joint micromotion in pelvic disruption.

OBJECTIVE: To measure the sacroiliac (SI) joint micromotion when different ligamentous lesions are created to simulate various degrees of pelvic anteroposterior compression injury. DESIGN: Cadaveric study. MATERIALS AND METHOD: Six SI joints were studied using a special device that made it possible to vary up to 310 N the loads applied on the ischial tuberosity and to measure simultaneously the SI micromotion. RESULTS: SI micromotion increases when the sacrospinous and sacrotuberous ligaments, and even more when the interosseous ligaments, have been sectioned off. In these cases, the stability of the SI joint is not restored by an isolated pubic fixation. CONCLUSION: This microinstability of the SI joint could contribute to the pain and arthritic changes sometimes observed in patients after anteroposterior compression injury. These experimental results could justify a larger spectrum of indications of SI joint fixation, but this should be confirmed by clinical study.

Effects of different treatment modalities on gait symmetry and clinical measures for sacroiliac joint patients.

The purpose of this study was to assess the effects of two different treatment modalities on the rehabilitation process of chronic sacroiliac joint patients. The treatment modalities included spinal manipulative therapy given by a chiropractor and a program of back school therapy given by a physiotherapist. The rehabilitation process was assessed using clinical and biomechanical measures. It was found that back school therapy was a better treatment modality than the spinal manipulative therapy, according to the clinical measures of rehabilitation. Precisely the opposite result was found for the biomechanical measures.

Injuries of the acetabular triradiate cartilage and sacroiliac joint.

Four patients with injuries of the acetabular triradiate cartilage are presented. In three of them premature fusion of the cartilage occurred; two of these developed acetabular deformity and subluxation of the hip. In all patients the sacroiliac joint also was injured; in two, the joint was completely disrupted, leading to fusion and growth disturbance of the ilium. As injury of the triradiate cartilage is easily missed on the initial radiograph, it is advised that all patients with pelvic trauma should be followed clinically and radiographically for at least one year.

Magnetic resonance imaging guided corticosteroid injection of sacroiliac joints in patients with spondylarthropathy. Are multiple injections more beneficial?

Efficacy of a second magnetic resonance (MR) imaging guided corticosteroid injection of inflamed sacroiliac joints (SIJ) in patients with spondylarthropathy. Thirty-one patients received 50 injections in an outpatient basis. Fifteen of 31 patients who relapsed or were non-responders received a second injection. All had MR guided injection of 40 mg triamcinolone acetonide into SIJ using an open 0.2 Tesla unit. Twenty of 31 patients after the first injection, and 9 of 15 patients after the second injection reported subjective improvement, which lasted for a mean of 8.7+/-10.9 and 16.1+/-15.8 months for each group. Subchondral bone marrow edema resolved in 15 of 20 patients who reported subjective improvement, after the first injection. No complications occurred. MR guided steroid injection of SIJ is effective and safe. Since there is no exposure to radiation it could be performed many times. Repeated injections seem to be beneficial for primary non-responders and patients who relapsed.

Pubic osteolysis mimicking a malignant lesion: report a case with a fracture dislocation of the sacroiliac joint.

We report the case of a 67-year-old woman who presented to our institution with osteoblastic and osteolytic lesions of the pubis and fracture dislocation of the left sacroiliac joint. She had presented 7 months earlier to an outside institution with a left gluteal mass, which had been biopsied and had been believed to represent malignancy. A second biopsy at our institution showed no evidence of malignancy and was felt to represent fracture healing. A diagnosis of public osteolysis was made based on the radiographic and histologic findings. A follow-up radiograph 6 years after presentation revealed healing of the lesions, confirming its benignity.

Normal morphology of sacroiliac joints in children: magnetic resonance studies related to age and sex.

OBJECTIVE: To determine in a prospective study the normal MRI morphology of the sacroiliac joints (SIJs) in relation to age and sex during adolescence. DESIGN AND PATIENTS: A total of 98 children (63 boys, mean age 12.7 +/- 2.8 years; 35 girls, mean age 13.7 +/- 2.3 years), ranging in age from 8 to 17 years, with juvenile chronic arthritis (JCA) but without signs of sacroiliitis fulfilled the study prerequisites (no back pain and no pathologic changes of the SIJs on physical examination before MRI in a 1.5-year follow-up). An additional eight HLA-B27-negative boys and eight HLA-B27-negative girls without arthritis served as controls. The MRI protocol comprised a T1-weighted SE sequence, an opposed-phase T2*-weighted GE sequence, and a dynamic contrast-enhanced study in single-section technique. RESULTS: Noncontrast MRI permitted differentiation of "open" from ossified segmental and lateral apophyses of the sacral wings, with a significant difference in age (P < 0.05) between children with open and ossified apophyses. Ossification of the apophyses of the sacral wings was seen significantly earlier (P < 0.05) in girls than in boys. Girls also had a significantly higher incidence of transitional lumbosacral vertebrae, pelvic asymmetries, and accessory joints. In the contrast-enhanced opposed-phase MRI study, normal cartilage of the SIJs showed no contrast enhancement whereas the joint capsule showed a moderate enhancement. CONCLUSION: There are significant age- and sex-related differences in the normal MRI morphology of juvenile SIJs. Our findings might serve as a standard of comparison for the evaluation of pathologic changes--in particular for the early identification of juvenile sacroiliitis.

Osteophyte at the sacroiliac joint as a cause of sciatica: a report of four cases.

Four cases of sciatica due to osteophytes impinging on the sciatic nerve at the sacroiliac joint are reported. Of these 4 cases, 2 were treated conservatively and the other 2 required surgical excision of the osteophyte. The report highlights the importance of keeping this uncommon etiology in the differential diagnosis of sciatica.

[Corticosteroid injections of the sacroiliac joint during magnetic resonance: preliminary results].

PURPOSE: The aim of this study was to evaluate the advantages of MRguided injections of corticosteroids into the sacroiliac joints (SIJ) in patients suffering from refractory sacroiliitis despite appropriate oral therapy. MATERIALS AND METHODS: At a lowfield open MR, we performed twentyfour infiltrations in 12 patients suffering from persistent buttock pain. Clinical followup and laboratory findings were evaluated every 4 up to 6 weeks. A subjective rating using a dolorimetry scale (0= no pain, up to=10 for most severe pain) was assessed prior to intervention and at three months followup. Morphological changes of the SIJ were examined on a 1.5 Tesla imager before and three months after steroid injections. RESULTS: Adequate positioning of the needle was obtained in all but one case due to a software defect. Clinical improvement was observed in 10 patients with a mean painfree period of 9.6 months. Dolorimetry index decreased from 7.6 +/- 1.5 to 2.9 +/- 1.5. Nonsteroidal antiinflammatory drugs could be discontinued in 4 patients and reduced in 4 others. CONCLUSION: We therefore conclude that MRguided injection of the SIJ is feasible and could be preferred to more conventional methods when technical equipment is available.

The reliability of selected motion- and pain provocation tests for the sacroiliac joint.

The objective of the study was to assess inter-rater reliability of one palpation and six pain provocation tests for pain of sacroiliac origin. The sacroiliac joint (SIJ) is a potential source of low back and pelvic girdle pain. Diagnosis is made primarily by physical examination using palpation and pain provocation tests. Previous studies on the reliability of such tests have reported inconclusive and conflicting results. Fifty-six women and five men aged 18-50 years old were included in the study. Fifteen patients had ankylosing spondylitis; 30 women had post partum pelvic girdle pain for more than 6 weeks; and 16 people had no low back or pelvic girdle pain. All participants were examined twice on the same day by experienced manual therapists. Percentage agreement and kappa statistic were used to evaluate the tests reliability. Results showed percentage agreement and kappa values ranged from 67% to 97% and 0.43 to 0.84 for the pain provocation tests. For the palpation test the percent agreement was 48% and the kappa value was -0.06. Clusters of pain provocation tests were found to have good percentage agreement, and kappa values ranged from 0.51 to 0.75. In conclusion this study has shown the reliability of the pain provocation tests employed were moderate to good, and for the palpation test, reliability was poor. Clusters out of three and five pain provocation tests were found to be reliable. The cluster of tests should now be validated for assessment of diagnostic power.

The relationship of lumbosacral plexus to the sacrum and the sacroiliac joint.

The lumbosacral plexus was dissected bilaterally in 20 adult cadavers to define the anatomic relationship of the lumbosacral plexus to the sacrum and the sacroiliac joint. All results are mean values +/- standard deviation. The length of the nerve roots of the lumbosacral plexus gradually decreased from L-4 to S-3 (from 93.8 +/- 6.9 mm in males and 108.7 +/- 7.7 mm in females at L-4 to 43.7 +/- 4.3 mm in males and 49.0 +/- 7.6 mm in females at S-3). The angle projected by the nerve roots of the lumbosacral plexus with respect to the sagittal plane gradually increased from L-4 to S-3 (from 14.3 degrees +/- 3.4 degrees in males and 16.7 degrees +/- 4.8 degrees in females at L-4 to 51.8 degrees +/- 9.0 degrees in males and 57.8 degrees +/- 9.1 degrees in females at S-3). The width of the nerve roots of the lumbosacral plexus was greatest at S-1 (9.8 +/- 1.8 mm in males, 8.6 +/- 1.5 mm in females). The L-5 nerve root was the thickest in males (4.4 +/- 0.5 mm), and the S-1 nerve root was thickest in females (4.3 +/- 0.4 mm). The lumbosacral trunk was 30.0 +/- 9.0 mm in length in males and 32.0 +/- 6.0 mm in females; 11.4 +/- 1.8 mm wide in males and 11.2 +/- 1.5 mm in females; and 4.4 +/- 0.5 mm thick in males and 4.0 +/- 0.6 mm in females. The fifth lumbar nerve root and lumbosacral trunk coursed across the sacroiliac at a level 2.0 +/- 0.2 cm below the pelvic brim and were relatively fixed to the sacral ala with fibrous connective tissue.

Fluoroscopy-guided sacroiliac joint injections.

The authors performed fluoroscopy-guided sacroiliac (SI) joint injections. With the patient prone and the x-ray tube perpendicular to the fluoroscopic table, the skin was marked over the distal 1 cm of the SI joint. With the tube angled 20 degrees - 25 degrees cephalad, a 22-gauge needle was inserted at the skin mark and advanced perpendicular to the fluoroscopic table toward the posterior joint. Nonionic contrast material was injected to confirm the intraarticular position of the needle. Of 31 SI joint injections, 30 (97%) were intraarticular. Mean procedure time was 108 seconds. This technique is safe, rapid, and reproducible.

Effective radiation dose from semicoronal CT of the sacroiliac joints in comparison with axial CT and conventional radiography.

The aim of this study was to evaluate the radiation dose given by semicoronal CT of the sacroiliac joints (SIJs) in comparison with axial CT and conventional radiography. The total effective radiation doses given by serial contiguous semicoronal and axial CT, using 5-mm slices, 120 kV and 330 mAs, were determined by measurement of organ doses using an anthropomorphic Rando Alderson phantom paced with thermoluminescence dosimeters. The doses given by conventional antero-posterior (AP) and oblique projections of the SIJs were determined similarly. In a female the total effective dose by semicoronal CT was found to be more than six times lower than by axial CT and 2.5 times lower than the dose use to obtain a conventional AP radiograph, the values being 102, 678, and 255 micro Sv, respectively. The effective dose by semicoronal CT was only a little higher than the dose given to obtain two oblique radiographs. In a male with lead protection of the gonads the dose by semicoronal CT was four times lower than by axial CT, but higher than by conventional radiography. In conclusion, the effective dose by semicoronal CT of the SIJs is lower than by axial CT, and in females a semicoronal CT implies a lower effective radiation dose that used to obtain an AP radiograph.
