An ulnar styloid fracture is a break in the small bony projection at the distal end of the ulna (the ulnar styloid process). Often this injury occurs in association with a wrist fracture, particularly a fracture of the distal radius. Although the styloid itself may seem secondary, its involvement can influence wrist stability, especially at the distal radioulnar joint (DRUJ). Anatomy and Biomechanics The ulna … Continue reading Ulnar Styloid Fracture
Ulnar tunnel syndrome, also known as entrapment of the ulnar nerve at the wrist, involves compression of the ulnar nerve as it passes through the ulnar tunnel (or Guyon’s canal) near the wrist. This condition often leads to tingling, numbness, or weakness affecting the little finger and part of the ring finger. When left untreated, it may lead to loss of fine motor control, grip … Continue reading Ulnar Tunnel Syndrome
A vertebral fracture is a break, crack or collapse of one or more of the bones (vertebrae) in the spinal column. These fractures may occur as a result of high-energy trauma, such as a vehicle collision or fall from height, or from weakened bones in low-energy events, such as in osteoporosis. Disruption of the vertebra may alter spinal alignment, compromise structural support, impair nerve or … Continue reading Vertebral fracture
A wrist fracture refers to a break in one or more of the bones around the wrist joint, most commonly the distal end of the radius. Because the wrist plays a key role in hand movement, grip strength and daily activities, a fracture in this region may significantly affect function and requires prompt assessment and appropriate treatment. Anatomy and Biomechanics The wrist encompasses the distal … Continue reading Wrist Fracture
Alkaptonuria arthropathy is a joint condition that develops in individuals with Alkaptonuria, a rare metabolic disorder. In this condition, excess homogentisic acid accumulates and deposits in joint cartilage and connective tissues, leading to pigmentation, cartilage degeneration, and chronic arthritic changes. Over time, this process results in joint pain, stiffness, and impaired function. Pathophysiology In alkaptonuria, the enzyme that normally breaks down homogentisic acid is deficient. … Continue reading Alkaptonuria arthropathy
