Diagnostic evaluation of open knee injuries: a comparison of arthrography and CT scans.

Article Synopsis
- The study examines knee arthrography as a potential diagnostic tool for open knee injuries, comparing its effectiveness to the gold standard of CT scans, which have downsides like cost and radiation exposure.
- Conducted with 43 patients, the study found that CT scans diagnosed open knee injuries in 11.6% of cases, while knee arthrography showed high sensitivity (83.3%) and specificity (96.5%).
- The results suggest that knee arthrography could be a safer and more cost-effective alternative to CT scanning for diagnosing open knee injuries, especially when considering the risks of radiation.
Closed Intramedullary Pinning of Displaced Radial Neck Fracture (Metaizeau Technique).

Background: Radial neck fractures account for 1% of all pediatric fractures and 5% to 10% of pediatric elbow fractures. The mechanism of injury is typically a fall with the elbow in hyperextension and the forearm in supination. A valgus force compresses the radial head against the capitellum, causing a radial neck fracture.

Imaging plays a critical role in the preoperative and postoperative evaluation of patients with femoroacetabular impingement. Non-contrast MR imaging and direct magnetic resonance arthrography of the hip are the modalities of choice for the preoperative assessment of chondrolabral lesions. The MRI protocol should include radial images for detailed analysis of the cam deformity and fast sequences covering the pelvis and knee for measurement of femoral torsion.

Acetabular labral tears are a mechanical cause of hip pain. Hip MR imaging should be performed on 3T magnets using small field of view and high-resolution imaging. If using a lower strength magnet, direct arthrography should be performed.

Department of Orthopedic Surgery, Iwate Medical University, Iwate, Japan.
Background: This study aimed to clarify the characteristic features of the anteroinferior and posterosuperior popliteomeniscal fascicles (aiPMF and psPMF, respectively) and popliteal hiatus using three-dimensional (3D) reconstructions of 7 T magnetic resonance imaging (MRI) arthrography.
Methods: Six knees from human cadavers fixed using the Thiel embalming method were examined using 7 T MRI arthrography. 3D Images of the structures around the popliteal hiatus were reconstructed.
