The prevalence of sesamoid bones in the hands has been reported in some previous articles. Most of them, however, have reported sesamoid bones of the metacarpophalangeal joint of the hand and of the interphalangeal (IP) joint of the thumb. The present study investigates the prevalence of sesamoid bones of the IP joint of the thumb and fingers. A retrospective review of radiologic views of the IP joints in the thumb or fingers was performed, including a total of 650 patients (1,096 thumbs or fingers). Sesamoid bones were found in the IP joint of the thumb at 67% (212 of 318), while the index, middle, ring, little fingers had sesamoid bones in the proximal interphlangeal (PIP) joint at 0% (0 of 172), 0.4% (1 of 244), 0.5% (1 of 183), and 1% (2 of 179), respectively. None of the four fingers had sesamoid bones in the distal IP joint. Previous articles have described the similar prevalence to the present study, of sesamoid bones of the IP joint of the thumb, while some others reported the different prevalence. About the PIP joint, no previous articles have found a sesamoid bone. Because the lateral X-ray view is more accurate and suitable to evaluate sesamoid bones, we used the lateral one for the present study. The knowledge that sesamoid bones occurs at these rates in the thumb IP joint and finger PIP joints is helpful to differentiate chip fractures from sesamoid bones near the IP joint, including the PIP joint.

His training at NYU helped Dr. Stelnicki bring innovations such as nasoalveolar molding for the treatment of cleft lip and palate, new methods of mandible and maxillary distraction for reshaping jaw bones, endoscopic surgery for the treatment of craniosynostosis, virtual surgical planning for facial reconstruction, and many other advances to South Florida.
An 3T MRI produces a high-powered magnetic field. A 3T is one of the highest-powered MRI machines and meets special considerations or protocols to fulfill certain diagnostic criteria for the referring physician. The 3T MRI produces clear images ideal for imaging small bones, breast tissue, musculoskeletal structures, spine, and vascular flow. The large 70cm bore opening enhances patient comfort to reach a wider range of patients including larger bodies and those who struggle with claustrophobia.
An x-ray (radiograph) is a quick, painless medical test that helps physicians diagnose and treat medical conditions. Radiography involves exposing a part of the body to a small dose of ionizing radiation called electromagnetic waves. The various body tissues absorb the radiation differently, creating different shades in an image to produce pictures of the inside of the body. Calcium in the bones absorbs radiation the most, so bones appear bright white while soft tissues absorb less and look gray. Air absorbs the least, so lungs and empty spaces appear black. X-rays are great for looking for broken bones or scarring in the lungs. 59ce067264
