The purpose of this study was to identify association between magnetic resonance imaging (MRI) features and clinical data at baseline and six months following platelet-rich plasma (PRP) or corticosteroid (CS; cortivazol) injection in patients with plantar fasciitis, and to identify initial MRI criteria associated with a favorable clinical response to treatment.The study was registered on ClinicalTrials.gov (NCT03857334). MRI examinations of 36 patients with plantar fasciitis lasting more than 3 months who were randomly assigned to receive ultrasound-guided PRP (PRP group, 20 patients) or CS (CS group, 18 patients) injection were quantitatively and qualitatively analyzed with respect to plantar fascia thickness, plantar fascia hyperintensity on T2-weighted STIR (HSTIR) images, calcaneal bone marrow and surrounding soft tissues. Clinical evaluation including visual analytic scale (VAS) assessment and MRI examinations were obtained before and 6 months after treatment. Good clinical response was defined as pain VAS decrease50% at 6 months. ROC curves with AUC measurements were used to determine cut-off points.In the whole study population, an association was found between MRI features (deep soft tissue and calcaneal bone marrow HSTIR) and pain VAS scores for the first steps of the day (P = 0.028 and P = 0.007, respectively). No significant radioclinical associations on post-treatment MRI examinations were found in either group. Initial coronal thickness of plantar fascia was associated with a good clinical response in the CS group (P0.01). ROC curve analysis found that 7-mm or thicker plantar aponeurosis at initial MRI was predictive of good clinical response in patients with CS treatment (Youden index = 0.6). PRP infiltrations were effective regardless of fascia thickness (73% of patients with ≤ 7 mm aponeurosis and 67% for thicker ones).Initial facia thickness (7 mm) is predictive of good clinical response six months after CS injection, whereas PRP injection shows effectiveness regardless of fascia thickness.

Background Our aim was to describe the characteristics of vertebral fractures, the presence of associated injuries, and clinical status within the first days in a severe trauma population. Methods All patients with severe trauma admitted to our level 1 trauma center between January 2015 and December 2018 with a vertebral fracture were analyzed retrospectively. The fractures were determined by the AO Spine classification as stable (A0, A1, and A2 types) or unstable (A3, A4, B, and C types). Clinical status was defined as stable, intermediate, or unstable based on clinicobiological parameters and anatomic injuries. Severe extraspinal injuries and emergent procedures were studied. Three groups were compared: stable fracture, unstable fracture, and spinal cord injury (SCI) group. Results A total of 425 patients were included (mean ± SD age, 43.8 ± 19.6 years; median Injury Severity Score, 22 [interquartile range, 17-34]; 72% male); 72 (17%) in the SCI group, 116 (27%) in the unstable fracture group, and 237 (56%) in the stable fracture group; 62% (95% confidence interval [CI], 57-67%) had not a stable clinical status on admission (unstable, 30%; intermediate, 32%), regardless of the group (p = 0.38). This decreased to 31% (95% CI, 27-35%) on day 3 and 23% (95% CI, 19-27%) on day 5, regardless of the group (p = 0.27 and p = 0.25). Progression toward stable clinical status between D1 and D5 was 63% (95% CI, 58-68%) overall but was statistically lower in the SCI group. Severe extraspinal injuries (85% [95% CI, 82-89%]) and extraspinal emergent procedures (56% [95% CI, 52-61%]) were comparable between the three groups. Only abdominal injuries and hemostatic procedures significantly differed significantly (p = 0.003 and p = 0.009). Conclusion More than the half of the patients with severe trauma had altered initial clinical status or severe extraspinal injuries that were not compatible with safe early surgical management for the vertebral fracture. These observations were independent of the stability of the fracture or the presence of an SCI. Level of evidence Prognostic and epidemiological, level III.

Resume Introduction Le conflit ischio-femoral est l’une des nombreuses causes de coxalgies. Messages principaux Il s’agit pathologie abarticulaire de la hanche caracterisee par des douleurs secondaires a un retrecissement de l’espace situe entre l’ischion et le petit trochanter. Ce retrecissement peut etre congenital, acquis ou positionnel. L’IRM est l’examen de choix, a la recherche notamment d’un œdeme du muscle carre femoral. Des signes associes permettent de sensibiliser l’examen. Le radiologue a non seulement un role dans le diagnostic mais egalement dans la prise en charge puisque l’infiltration de corticoides sous guidage scanographique ou echographique represente a la fois un test diagnostic et une composante a part entiere du traitement des patients. Conclusion Les radiologues se doivent de connaitre cette pathologie relativement frequente, et ce d’autant qu’ils ont un role a la fois dans le diagnostic de la pathologie que dans son traitement.

Resume Introduction Les tumeurs benignes a cellules notochordales (TBCN) sont des lesions de decouverte le plus souvent fortuite a l’occasion d’un bilan d’imagerie explorant le clivus, les corps vertebraux du rachis mobile ou la region sacro-coccygienne. Messages principaux Les TBCN se presentent de facon typique sous la forme d’une lesion arrondie de taille Conclusion Savoir identifier une TBCN est important afin de proposer une conduite a tenir appropriee. Une abstention est la regle en cas d’aspect typique, une biopsie doit en revanche etre discutee dans le cas contraire.

As many other European countries, France has to deal with a growing number of migrants including some who contend age minority entitling them to benefits and privileges reserved for children within the context of legal proceedings. In case of doubtful minority, medical examinations may be carried out to assess skeletal and dental age. Our objective was to analyse the age assessments regarding individuals of doubtful minority assertion at the Medico-legal Institute of the University Hospital of Montpellier since 2018.Expert reports of forensic age assessments performed during the 2018-2021 period were reviewed. Demographic data and results from medical and radiological investigations based on AGFAD recommendations were recorded in each case. When available, conclusions of judicial investigations about the individuals' actual age were collected.A total of 265 reports were compiled. Age assessments predominantly concerned males (97.7%) and the main reported country of origin was sub-Saharan Africa (80.4%). The mean reported age was 16.3 ± 0.8 years. The individual's stated age was compatible with the age assessment in 31 cases (11.7%), while expert reports concluded that the age of majority had been reached in 131 cases (49.4%). In cases of discrepancies, the average difference between the stated and the assessed lowest possible age (= assessed minimum age) was 2.7 ± 2.3 years and 6.9 ± 3.8 years between the stated and the most probable age. Age assessments could be compared with actual ages determined by court proceedings in 27 cases, with established ages being systematically higher than the assessed minimum ages (mean difference = 4.4 ± 4.0 years). The difference between actual and stated ages ranged from 1.8 up to 18.9 years (mean difference = 6.4 ± 4.0 years). The used protocol never led to any age overestimation in this population.Our study reinforces the relevance of AGFAD recommendations for forensic age assessment and calls for the harmonization of practices based on this methodology in the European countries.
