Assessment of irreducible aspects in developmental hip dysplasia by magnetic resonance imaging

Abstract We aimed to assess the diagnostic capability of magnetic resonance imaging (MRI) for irreducible aspects preventing hip reduction in developmental dysplasia of the hip(DDH). With pathological results or intraoperative findings as the gold standard, the sensitivity and specificity of MRI were 90.3% and 83.3% for the affected labrum, 92% and 83.3% for thickening of the round ligament, 90.0% and 91.3% for atrophy of the iliopsoas muscle, and 100% and 100% for fibrofatty pulvinar tissue and joint effusion, respectively. The MRI showed an extraordinary capability of detecting these irreducible factors and helped surgeon choose the appropriate treatment strategies.

AbstractAnal fistula (AF) is a common referral to colorectal surgeons. Management remains challenging and sometimes controversial. Magnetic resonance imaging (MRI) is commonly performed in initial workup for AF. However, reports often lack key information for guiding treatment strategies. It has been shown that with structured radiology reports, there is less missing information. We present a structured MRI template report including 8 key descriptors of anal fistulas, whose effectiveness and acceptability are being assessed in a cross-sectional study (NCT04541238).

Objective.To evaluate the utility of magnetic resonance imaging (MRI) in systemic sclerosis (SSc)-associated arthropathy.Methods.MRI of the hand was performed in patients presenting with joint pain/swelling in order (1) to determine the frequency of inflammation on MRI, and (2) to compare MRI with radiography.Results.Of 17 patients with SSc, 10 (59%) had inflammatory MRI findings with synovitis (n = 8), erosions (n = 7), joint effusion (n = 7), or tenosynovitis (n = 8). Bone edema was present in 9 patients. Of 7 patients with MRI erosions, only 2 had radiographic erosions.Conclusion.Our study illustrates the usefulness of MRI in the accurate diagnosis and characterization of SSc-associated arthropathy.

Abstract Background：The developmental dysplasia of the hip (DDH) can cause a wide range of pathological changes, and often requires surgical treatment. Preoperative evaluation is very important for DDH. We aimed to assess the diagnostic capability of magnetic resonance imaging (MRI) for irreducible aspects preventing hip reduction in DDH. Methods: A total of 39 pediatric patients who received DDH evaluation in pediatric orthopedics from January 2015 to December 2019 were included. The samples included 4 cases of bilateral DDH and 35 cases of unilateral DDH, a total of 43 hip joint samples. All patients underwent surgical treatment, pathological examination and MRI of hip joint.Results: With pathological results or intraoperative findings as the gold standard, the sensitivity and specificity of MRI were 90.3% and 83.3% for the affected labrum, 92% and 83.3% for thickening of the round ligament, 90.0% and 91.3% for atrophy of the iliopsoas muscle, and 100% and 100% for fibrofatty pulvinar tissue and joint effusion, respectively.

: We presented a 5-year-old boy with fever, limping, and hip pain for six days. There was no abnormal past medical history. He kept his left leg immobile and slightly flexed, and externally rotated in the hip joint. Laboratory findings showed leukocytosis and elevated ESR and CRP. Hip sonography was normal. Hip magnetic resonance imaging (MRI) found no joint effusion but elucidated signs of inflammation in muscles of the periarticular and proximal femoral area (iliopsoas and gluteus maximus), and no collection could be noticed. We provided a thorough discussion on differential diagnoses and approaches to the patient.

Objective.There is increasing evidence that early therapeutic intervention improves longterm joint outcome in juvenile idiopathic arthritis (JIA). Given the existence of highly effective treatments, there is an urgent need for reliable and accurate measures of disease activity and joint damage in JIA. Our objective was to assess the reliability of 2 magnetic resonance imaging (MRI) scoring methods: the Juvenile Arthritis MRI Scoring (JAMRIS) system and the International Prophylaxis Study Group (IPSG) consensus score, for evaluating disease status of the knee in patients with JIA.Methods.Four international readers independently scored an MRI dataset of 25 JIA patients with clinical knee involvement. Synovial thickening, joint effusion, bone marrow changes, cartilage lesions, bone erosions, and subchondral cysts were scored using the JAMRIS and IPSG systems. Further, synovial enhancement, infrapatellar fat pad heterogeneity, tendinopathy, and enthesopathy were scored. Interreader reliability was analyzed by using the generalized κ, ICC, and the smallest detectable difference (SDD).Results.ICC regarding interreader reliability ranged from 0.33 (95% CI 0.12–0.52, SDD = 0.29) for enthesopathy up to 0.95 (95% CI 0.92–0.97, SDD = 3.19) for synovial thickening. Good interreader reliability was found concerning joint effusion (ICC 0.93, 95% CI 0.89–0.95, SDD = 0.51), synovial enhancement (ICC 0.90, 95% CI 0.85–0.94, SDD = 9.85), and bone marrow changes (ICC 0.87, 95% CI 0.80–0.92, SDD = 10.94). Moderate to substantial reliability was found concerning cartilage lesions and bone erosions (ICC 0.55–0.72, SDD 1.41–13.65).Conclusion.The preliminary results are promising for most of the scored JAMRIS and IPSG items. However, further refinement of the scoring system is warranted for unsatisfactorily reliable items such as bone erosions, cartilage lesions, and enthesopathy.

SummaryThis case report describes the diagnosis and management of primary femoral nerve sheath tumours in two dogs. Both of the tumours were localised by electromyography (EMG) and magnetic resonance imaging (MRI), and were then surgically resected using a novel approach to the iliopsoas muscle via osteotomy of the ventral ilial wing. This approach should be considered when attempting surgical treatment of conditions affecting the iliopsoas muscle or the femoral nerve because it provides excellent exposure of these structures.
