Diagnostic accuracy of digital radiography for the diagnosis of osteonecrosis of the femoral head, revisited.

Conclusion Diagnostic performance of digital radiography for ONFH revealed low sensitivity and poor-to-moderate inter-reader agreement for diagnosing pre-collapse ONFH. There was no additional value of the frog-leg view. PMID: 30326729 [PubMed - as supplied by publisher]

J Knee Surg DOI: 10.1055/s-0039-1700978To improve the long-term outcomes of high tibial osteotomy (HTO) for gonarthritis, many cartilage repair procedures appeared, but their effects were controversial. To evaluate the efficacy of cartilage repair procedures during HTO for gonarthritis, we performed this update meta-analysis. We performed the system retrieval for clinical trials using various databases and then pooled the outcomes of the included studies. Fifteen studies were involved. The pooled results indicated that there were no significant differences in Kellgren and Lawrence (KL) scale (mean difference [MD] =&...

Biologic failures of hip replacement have emerged as an increasing threat to the longevity of the prosthesis. While wear of modern day bearings has been greatly reduced with the advent of cross linked polyethylene, local reaction to metal particles either from the bearing itself or to any of the modular tapers appears to be on the rise. Monitoring of these reactions by the use of plain radiographs or serum markers appears to be insufficient to gauge the gravity of the response.Over the past decade, the use of magnetic resonance imaging (MR) techniques has emerged as the superior noninvasive instrument to assess the extent ...

We compared the assessment of active synovitis in knee osteoarthritis (OA) by utilising superb microvascular imaging (SMI) and conventional power Doppler (cPD) techniques, and then correlated each technique with paients' symptoms, radiographic features and magnetic resonance imaging (MRI)-detected synovitis. A subgroup of participants with symptomatic knee OA underwent dynamic ultrasound assessment for semi-quantitative scores for SMI and cPD in the suprapatellar, medial and lateral parapatellar knee recesses.

DCE-MRI is established for detecting prostate cancer (PCa). However, it requires a gadolinium contrast agent, with potential risks for patients. The application of DIR-MRI is simple and may allow cancer detection without the use of an intravenous contrast agent by differentially nullifying signal from normal and abnormal prostate tissue, creating contrast between the cancer and background normal prostate. In this pilot study we gathered data from DIR-MRI and DCE-MRI of the prostate for an equivalence trial.

Authors: Nakashima H, Kanemura T, Satake K, Ito K, Ishikawa Y, Ouchida J, Segi N, Yamaguchi H, Imagama S Abstract Study Design: Retrospective comparative study. Purpose: We compared clinical and radiographical outcomes after lumbar decompression revision surgery for restenosis by lateral lumbar interbody fusion (LLIF) and posterior lumbar interbody fusion (PLIF). Overview of Literature: Indirect lumbar decompression with LLIF was used to treat degenerative lumbar diseases requiring neural decompression. However, only a few studies have focused on the effectiveness of this technique for restenosis after lumb...

ConclusionsIn conclusion, when compared with current local practice, immediate referral of the patient with AST for MRI following one non-diagnostic ED radiograph is potentially cost-effective in establishing efficient diagnosis of scaphoid fractures. We recommend the implementation of published international guidelines in the investigation of query scaphoid fractures as a pragmatic and cost-effective practice.

AbstractObjectivesTo investigate the cross-sectional associations between suprapatellar pouch effusion-synovitis and serum levels of cartilage oligomeric matrix protein (COMP), high sensitivity C-reaction protein (hs-CRP), knee symptom, and structural changes in patients with symptomatic knee osteoarthritis (OA).MethodA total of 173 subjects were included. The osteophytes, joint space narrowing (JSN), and radiographic severity of OA were determined using X-ray. Cartilage defects, bone marrow lesions (BMLs), and suprapatellar pouch effusion-synovitis were assessed using magnetic resonance imaging. Serum levels of COMP and h...

AbstractStafne bone cavity (SBC) is a rare lingual bone depression that is asymptomatic and contains salivary glands. Radiographically, an SBC is usually seen as well-defined homogenous oval radiolucency in the mandibular posterior region, below the mandibular canal. In this paper, a rare case of posterior-variant, double SBCs was presented. A 43-year old male patient was referred to our clinic with the complaint of third molar teeth. Panoramic and cone-beam computed tomographic images showed two well-defined oval radiolucencies on the left mandibular molar region, inferior to mandibular canal borders. No pain or swelling ...
