Previous Implant Fractures: A New Descriptive Classification System

Objectives: To propose a previous implant fractures (PIFs) classification system with good interobserver reliability. Design: Retrospective classification. Setting: Four academic medical centers. Patients/Participants: A retrospective review of PIFs treated at 4 academic medical centers over 10 years was performed. Data collected included initial implant and PIF radiographs. There were 103 PIFs in 96 patients during the study period. Seventy-three (70.9%) were about plate/screw (PS) constructs and 30 (29.1%) were about intramedullary (IM) devices. Intervention: Assignment of PIF classification. Main Outcome Measurements: PIFs were classified based on initial implant (PS or IM) and fracture location with respect to the initial implant (proximal or distal to the implant, at the tip of the construct, or within the construct). Reliability of this scheme was assessed among 5 observers using Fleiss' kappa tests. Results: Of PIFs about plate/screw constructs, 26.0% were proximal/distal to the implant (classification: PS1), 57.5% involved bone between the most proximal/distal screw and the same end of the plate (classification: PS2), and 16.4% involved only bone between the most proximal and distal screws (classification: PS3). Of PIFs about IM, 43.3% were distal to the device (classification: IM1), 46.7% involved bone between the most proximal/distal locking bolt and the same end of the device (classification: IM2), and 10.0% involved only bone between locking bo...

They often recur after simple conservative surgeries, such as enucleation. The dredging method was thus developed as an alternative, conservative treatment of ameloblastoma. This method accelerates new bone formation and enables surgeons to remove all tumors, leading to lower r...

Authors: Tsai YC, Lee HL, Kuo CC, Chen CY, Hsieh KL, Wu MH, Wen YC, Yu HW, Hsu FC, Tsai JT, Chiou JF Abstract Background: Magnetic resonance-guided focused ultrasound surgery (MRgFUS) is an alternative local therapy for patients with painful bone metastasis. However, little is known about the prognostic and predictive factors of MRgFUS in treating bone metastasis. Materials and methods: This retrospective study analyzed the performance status, treated site, pretreatment pain score, pretreatment tumor volume and lesion coverage volume factor (CVF) of 31 patients who underwent MRgFUS. A numerical rating scale for pai...

CONCLUSION: DAS28 score and disease activity are strong indicators of TMJ affection in RA patients when compared to RF and ACCP. ACCP is a better indicator of changes in condylar measurements than TMJ osteoarthritic changes. While RF is the least efficient indicator of TMJ involvement in RA patients.

CONCLUSIONS: The results emphasize the need for a cautious approach to using dental CBCT. Imaging only when the clinical indications are clear, accompanied with the appropriate radiographic techniques and the optimum imaging protocol, will help reduce radiation dose to patients.

Conclusion Gait variability improved after total hip arthroplasty due to improved hip function. However, trunk variability was insufficient compared with that in healthy individuals.

This study seeks to evaluate the use of CR in children with bronchiolitis due to a lower respiratory tract infection (RSV-RTI) with respiratory syncytial virus (RSV) and the influence of CR on patient treatment during the 2010-2017 seasons. There were 581 children included into the study: 459 with bronchiolitis (390 RSV-RTI and 69 non-RSV), 65 with RSV pneumonia and 57 with RSV bronchitis. We found that CR was performed in 28.6% (166/581) patients. CR was much more frequent in patients with RSV than non-RSV infections (61% vs. 31%). CR prognostic sensitivity and specificity in guiding antibiotic treatment was low, 78% and ...

Authors: Waninger JJ, Green M, Cheze Le Rest C, Rosen B, El Naqa I Abstract In radiomics, quantitative features that describe phenotypic tumor characteristics are derived from radiographic images. Because radiomics generates information from routine medical images, it is a powerful way to non-invasively examine the spatial and temporal heterogeneity of disease, and thus has potential to significantly impact clinical trial design, execution, and ultimately patient care. The aim of this review article is to discuss how radiomics may address some of the current challenges in clinical randomized control trials, and the...

CONCLUSIONS: Pelvic fracture MRI should be performed primarily in elderly female patients without adequate trauma. In patients with adequate trauma, MRI is of low value, especially as MRI diagnostics are performed with delay, resulting in later surgery. PMID: 31533165 [PubMed - as supplied by publisher]
