3D CT measures accurately for total knee arthroplasty

By Eric Barnes

Accurate implant alignment and ligament balance are essential for a successful total knee arthroplasty. These days CT is taking on a bigger role in presurgical planning, with increasing use of 3D measurements. And according to Korean researchers, the measurements based on 3D reconstructions are accurate and reproducible.

MR, x-ray show moderate correlation for assessing chronic hip pain

By Shalmali Pal

Up to 20% of older adults who undergo total hip arthroplasty may have underlying dysplasia. Traditionally, orthopedic surgeons have relied on x-ray to track dysplasia prior to treatment. Now, MRI studies are done more frequently. A group of researchers set out to find whether the two modalities offer the same kind of information for hip disorders.

Bone marrow edema on preop MR correlates with vertebroplasty success

By Shalmali Pal

On prevertebroplasty MRI, the loss of signal intensity from the vertebral bone marrow space is indicative of bone marrow edema. This information is useful for determining which vertebrae should be treated. Now, researchers in Japan have studied the direct connection between bone marrow edema patterns on preoperative MRI and clinical outcome after percutaneous vertebroplasty (PVP).
