Lumbrical muscle enhancement on MRI and its association with rheumatoid arthritis
ConclusionRA patients demonstrated significantly more frequent and stronger LME with substantial interrater agreement. LME could constitute a subtle radiological clue for early RA. (Source: Skeletal Radiology)

Safety of local anesthetics in cervical nerve root injections: a narrative review
AbstractSevere neurological adverse events have been reported after fluoroscopically guided cervical nerve root injections. Particulate corticosteroids inadvertently injected intraarterially and iatrogenic vertebral artery trauma have been implicated in these outcomes. This has raised concern for the potential consequences of including local anesthetic with these injections. As a result, some providers have now discontinued the routine administration of local anesthetic with corticosteroid when performing cervical nerve root injections. At present, there is no consensus regarding whether the use of local anesthetic in this...

Symptom-imaging correlation in lumbar spine pain
AbstractLumbar spine MRI is associated with a high prevalence of morphological abnormalities in both symptomatic and asymptomatic individuals. A difficult challenge, therefore, is distinguishing the relevant findings causing symptoms from incidental findings. The accurate diagnosis of pain generator is important because misdiagnosis can negatively impact patient management and outcome. Spine physicians use clinical symptoms and signs to interpret lumbar spine MRI and make treatment decisions. Symptom-MRI correlation enables the targeted inspection of images for pain generator. Radiologists can also use clinical information...

Parsonage-Turner syndrome following monkeypox infection and vaccination
AbstractBeginning in May 2022, monkeypox infection and vaccination rates dramatically increased due to a worldwide outbreak. This case highlights magnetic resonance (MR) neurography findings in an individual who developed Parsonage-Turner syndrome (PTS) 5 days after monkeypox symptom onset and 12 days after receiving the JYNNEOS vaccination. MR neurography of the patient ’s left suprascapular nerve demonstrated intrinsic hourglass-like constrictions, a characteristic finding of peripheral nerves involved in PTS. Other viral infections and vaccinations are well-documented triggers of PTS, an underrecognized peripheral neu...

Does radiolucency really predict loose components in revision shoulder arthroplasty?
ConclusionWhile RLL do not predict loosening of the implant in general, occurrence in more than one zone correlates with loosening. If located in distal zones and with increasing number of zones with RLL, the correlation becomes even stronger and loosening is more likely. (Source: Skeletal Radiology)

Muscle atrophy in diabetic patients with Charcot foot: a case-control study
ConclusionMuscle atrophy and muscle edema are significantly more severe in diabetic patients with CF disease. Muscle atrophy does not correlate with the severity of active CF disease. A CSA< 139 mm2 of the flexor digitorum brevis muscle in the hindfoot may indicate CF disease. (Source: Skeletal Radiology)

Deep branch of the radial nerve: effect of pronation/supination on longitudinal nerve alignment
ConclusionThe extremes of the rotational movement of the forearm affect the longitudinal morphology and anatomic relationships of the DBRN, primarily demonstrating the convergence of the nerve towards the SASM in maximal pronation and divergence in maximal supination. (Source: Skeletal Radiology)

Giant-cell-poor giant cell tumor of bone: report of two cases and literature review
AbstractGiant cell tumor of bone (GCTB) is a locally aggressive tumor that shows predilection for the metaphysis/epiphysis of long bones, with an incidence of 4 –5% of primary bone tumors. GCTB shows two main populations of cells: mononuclear cells and non-neoplastic multi-nucleated giant cells, with or without fibrous background. On the other hand, giant-cell-poor GCTB are rare with only few reports in the literature. These cases offer a diagnostic chall enge, given the absence of giant cells and such cases have consistently been shown to harbor theH3F3A gene mutation by sequencing. The H3.3 G34W mutation-specific monoc...

Feasibility of photon-counting CT for femoroacetabular impingement syndrome evaluation: lower radiation dose and improved diagnostic confidence
ConclusionsDose-matched PCD-CT is superior to EID-CT for alpha angle and acetabular version measurement in the work up of FAI. UHR-PCD-CT enables 50% radiation dose reduction compared to EID while remaining adequate for the imaging task. (Source: Skeletal Radiology)
