Orthopedic News and Research

RSS

Orthopedic surgery or orthopedics (also spelled orthopaedics) is the branch of surgery concerned with conditions involving the musculoskeletal system. Orthopedic surgeons use both surgical and non-surgical means to treat musculoskeletal trauma, sports injuries, degenerative diseases, infections, tumors, and congenital conditions.

Artificial intelligence tracks aging and damaged cells through high resolution imaging

A combination of high-resolution imaging and machine learning, also known as artificial intelligence (AI), can track cells damaged from injury, aging, or disease, and that no longer grow and reproduce normally, a new study shows.

Study shows how autism-linked picky eating causes serious vitamin deficiencies

Children with autism spectrum disorder (ASD) face a high risk of multiple micronutrient deficiencies, especially vitamins A, D, B12, and calcium, due to extreme food selectivity. These deficiencies can lead to severe health issues like rickets, vision loss, and immune dysfunction, even in children with normal body weight.
