AI Article Synopsis
- This study was retrospective, aiming to evaluate how often inflammatory features of lumbar facet joints are reported in MRIs of patients with chronic low back pain.
- It found that inflammatory characteristics like joint effusion and edema were mentioned infrequently in radiology reports, with low sensitivity (6%-22%) but variable positive predictive values (25%-100%).
- The study suggests that these features are not commonly identified in reports and calls for more research to understand their significance in pain mechanisms and clinical outcomes. *
Article Abstract
Study Design: Retrospective.
Objective: We aimed to assess the frequency of facet joint inflammatory features noted in routine radiology reports of lumbar spine magnetic resonance imaging (MRI) studies among patients with chronic low back pain.
Summary Of Background Data: Facet joint arthropathy is one of the most common causes of chronic low back pain. It may encompass various inflammatory imaging characteristics, such as facet joint effusion, bone marrow edema, and soft tissue edema. The extent to which radiology reports mention inflammatory features of the lumbar facet joints and the accuracy of these reports have not been investigated.
Materials And Methods: The authors performed a chart review on 49 subjects with previous facet-related interventions ( i.e . medial branch blocks or intra-articular facet joint injection) and MRI available in the medical record. One senior musculoskeletal radiologist and a musculoskeletal radiology fellow graded the inflammatory features using a published facet joint inflammation grading system [Gold Standard (GS)]. The authors identified the inflammatory markers mentioned in the radiology reports and calculated the sensitivity and positive predictive value of the radiology reports compared with GS readings.
Results: Compared with the GS, the sensitivity of radiology reports for facet joint effusion, bone marrow, and soft tissue edema ranged from 6% to 22%, and the positive predictive value ranged from 25% to 100%. L4/5 had the highest number of cases with inflammatory features noted on the reports.
Conclusion: Inflammatory findings, such as facet joint effusion, bone marrow edema, and soft tissue edema, are not commonly identified in radiology reports. Further investigations are needed to determine the clinical importance of MRI-detected lumbar facet joint inflammatory features as a potential mechanism of nociception and as a predictor of outcomes following injections or other therapies.

Background: Physicians worldwide face the challenging task of improving patient satisfaction by reducing pain in injured patients. Currently, available therapeutic approaches provide only short-term relief of symptoms without addressing long-term satisfaction. This has led to exploring regenerative treatment options that can deliver better outcomes.

Background: Loss of key-pinch sensation after median nerve injury poses significant functional detriment. Nerve transfers are utilized to improve function after nerve injury and size matching of donor and recipient nerves is important to optimize success. This anthropometric study investigates the anatomy of the superficial branch of the radial nerve (SBRN) to the thumb and index finger and explores radial to median sensory nerve transfers, a necessary but not heavily discussed facet of nerve transfers for the hand.

Objective: To report the outcomes of transoral C2 osteotomy (or partial odontoidectomy) and posterior fixation, regarding efficacy and safety, in patients with severe irreducible atlantoaxial dislocation (IAAD) following odontoid fracture.
Methods: Transoral C2 osteotomy, soft tissue resection, with or without facet joint release, followed by posterior fixation were performed on 3 patients (2012, 2016, 2023) who were suffering from severe IAAD after an odontoid fracture with spinal cord compression. The radiological and clinical outcomes were then assessed.

Introduction: The aim of this study was to establish an international consensus statement on the indications for the addition of a patellofemoral joint arthroplasty (PFJA) in patients with a unicondylar knee arthroplasty (UKA) and symptomatic progression of patellofemoral compartment osteoarthritis.
Materials And Methods: A systematic review of the literature was conducted, and the results used to inform the development of a statement by an expert working group. This was then evaluated and modified, using a Delphi process, by members of the European Knee Society (EKS).
