Detailed analysis of bone density changes and stem-femur contact after total hip replacement

Researchers at Osaka Metropolitan University assess why post-operative symptoms such as pins and needles, sudden cold, burning, itching, and numbness in the limbs remain in patients suffering from cervical spondylotic myelopathy, even after surgery. The researchers also evaluated the patients’ satisfaction with postoperative treatment. They found that it was lower for those who still had paresthesia in their hands and feet, regardless of whether their motor symptoms had improved or not.

Elucidating why some patients with specific joint deformities are symptomatic while others are not

Researchers from Osaka Metropolitan University Graduate School of Medicine conducted an interoperative comparison of lateral disc meniscus injuries of young patients (aged 15 or less), that were treated with plastic sutures or subtotal resection, to see if there was a difference in postoperative cartilage degeneration. The research group observed that sub-total meniscectomies were more likely to show cartilage degeneration, being worst in lateral disc meniscus injuries. In addition, they found that even with higher levels of meniscus damage, preserving the meniscus with sutures was more effective in protecting the cartilage in young patients.

Researchers analyze bone marrow-derived and peripheral blood-derived fibrin clots showing that the former contains more growth factors. They then show that bone marrow-derived fibrin clots can be used for meniscus suturing, even in the inner-most avascular regions, and with a 2-year post-operative follow-up, they show bone marrow-derived fibrin clots support healing better than their peripheral blood counterparts.
