Age-related prevalence and imaging characteristics of the superior acetabular roof notch in children, adolescents, and young adults
ConclusionSARN is a common finding on MRI and radiographs. The present data suggest that SARN undergoes an age-related imaging characteristic from a fluid-like appearance to a fat-like appearance on MRI during adolescence. (Source: Skeletal Radiology)

In-vivo kinematics of the trapeziometacarpal joint in dynamic pinch motion using four-dimensional computed tomography imaging
ConclusionThis study successfully employed 4D-CT to precisely demonstrate changes in rotation and translation at the trapeziometacarpal joint during pinch motion for various instantaneous forces. (Source: Skeletal Radiology)

Diagnostic yield and concordance of image-guided biopsy in musculoskeletal lesions
ConclusionThe null hypothesis is rejected. The main predictor of diagnostic biopsy was total specimen length, independent of number of cores taken. Three or more cores and longer cores are optimal, though these factors are influenced by lesion biology and not always able to be controlled. (Source: Skeletal Radiology)

Left fourth and sixth costovertebral dislocation abutting the aorta
We report a rare case of dislocation of the left fourth and sixth CVJs in a 36-year-old man who was run over by a car. The rib heads were displaced anteriorly, abutting the aorta. Additional injuries included bilateral hemopneumothoraces, pneumomediastinum, pulmonary contusions, grade 3 splenic injury, left adrenal hematoma, retroperitoneal hematoma, Morel-Lavall ée lesions at bilateral hips, and multiple fractures, including at the ribs and pelvis. There was also a fracture of the fourth thoracic vertebral body, which was occult on initial CT, but seen on subsequent CTs. The CVJ dislocations were managed conservatively, ...

“The accuracy of the EOS imaging system to assess hip abnormalities in adolescents and adults:” a systematic review and meta-analysis
ConclusionThe EOS imaging system has a high correlation with CT for preoperative and postoperative/prosthetic hip measurements, with considerably lower irradiation of patients. (Source: Skeletal Radiology)

Representation of women in musculoskeletal radiology conferences in Europe and North and South Americas: an estimation and comparative analysis
ConclusionWe evaluated the participation of women speakers in musculoskeletal radiology conference programs, with significant differences in Europe and South America in all years evaluated, and the participation of women moderators with significant differences in South America and in all-male panels in all regions. Acknowledging gender biases and increasing the number of women on planning committees may help address gender imbalance and promote gender equity. (Source: Skeletal Radiology)

Neurovascular structures to avoid during musculoskeletal ultrasound-guided intervention in the extremities
AbstractUltrasound is a useful modality for guiding injections and other procedures in the extremities. Its portability and the ability to adjust the probe and needle in real time, as well as lack of radiation exposure make it preferable for many routine procedures. However, ultrasound is highly operator dependent and a firm understanding of regional anatomy is important, including neurovascular structures that are in close proximity during many of these procedures. Knowledge of the characteristic location and appearance of neurovascular structures in the extremities allows safe needle advancement and prevention of iatroge...

Is total-body MRI useful as a screening tool to rule out malignant progression in patients with multiple osteochondromas? Results in a single-center cohort of 319 adult patients
ConclusionTB-MRI can identify malignant transformation of osteochondromas in HMO patients. All peripheral chondrosarcomas occurred in flat bones (ribs, scapula, pelvis) in our study. TB-MRI might assist in triage between higher risk patients with a high burden of OC, including the location of OC in main flat bones vs lower risk patients without OC of the flat bones.

The routine clinical use of fluorodeoxyglucose PET/CT to confirm treatment response in pyogenic spine infection
ConclusionRisk stratification proposed: A low-risk scan with only inflammation at a destroyed joint indicates negligible risk of recurrence. Unexplained activity in bone, soft tissue or spinal canal indicates high risk with further antibiotics recommended. Most patients with subtle or localized findings (intermediate risk) did not experience recurrence. Stopping therapy could be considered under careful observation. (Source: Skeletal Radiology)

Society of skeletal radiology position paper – recommendations for contrast use in musculoskeletal MRI: when is non-contrast imaging enough?
AbstractThe following White Paper will discuss the appropriateness of gadolinium administration in MRI for musculoskeletal indications. Musculoskeletal radiologists should consider the potential risks involved and practice the judicious use of intravenous contrast, restricting administration to cases where there is demonstrable added value. Specific nuances of when contrast is or is not recommended are discussed in detail and listed in table format. Briefly, contrast is recommended for bone and soft tissue lesions. For infection, contrast is reserved for chronic or complex cases. In rheumatology, contrast is recommended fo...

MRI 3D simulation of hip motion in female patients with and without ischiofemoral impingement
ConclusionHip MRI 3D models are feasible for simulated range-of-motion and show a higher frequency of extra-articular impingement at early stages of external rotation and extension in IFI compared to non-IFI hips. (Source: Skeletal Radiology)

Retracted os peroneum with partial integrity of the peroneus longus tendon
We present a case of a displaced proximal fragment of the os peroneum above the level of the ankle joint on radiographs and MRI associated with incomplete tear of the peroneus longus tendon. We hypothesize that such an injury pattern results from an anatomic prerequisite where the os peroneum occupies a portion of the cross-sectional diameter of the tendon. We suggest that the retracted proximal moiety of the sesamoid bone is the result of elastic recoil of delaminated fibers of the peroneus longus directly inserting on the os, whereas eccentric bundles of the tendon draping over the os remain in continuity. Although treat...
