An ulna fracture is a break in the ulna bone, one of the two bones in the forearm. [2] It is often associated with a fracture of the other forearm bone, the radius. [1] [3]An ulna fracture can be a single break as in a so called nightstick fracture, which can be caused by someone being hit on the inside of the forearm often by a stick, notably when they are holding their arm up to protect ...
The ulna or ulnar bone (pl.: ulnae or ulnas) [3] is a long bone in the forearm stretching from the elbow to the wrist. It is on the same side of the forearm as the little finger, running parallel to the radius, the forearm's other long bone. Longer and thinner than the radius, the ulna is considered to be the smaller long bone of the lower arm.
Surgical removal of a Heterotopic Ossification fusing the right Humerus and Radius following a severe TBI and complete fracture of the Ulna. Radiation Therapy. Elbow heterotopic ossification radiation therapy field, status post surgery. Prophylactic radiation therapy for the prevention of heterotopic ossification has been employed since the 1970s.
A distal radius fracture, also known as wrist fracture, is a break of the part of the radius bone which is close to the wrist. [1] Symptoms include pain, bruising, and rapid-onset swelling. [1] The ulna bone may also be broken. [1] In younger people, these fractures typically occur during sports or a motor vehicle collision. [2]
Accessory bones of the ankle. [13]Accessory bones at the ankle mainly include: Os subtibiale, with a prevalence of approximately 1%. [14] It is a secondary ossification center of the distal tibia that appears during the first year of life, and which in most people fuses with the shaft at approximately 15 years in females and approximately 17 years in males.
Fractures of the styloid process of the ulna seldom require treatment when they occur in association with a distal radius fracture. The major exception is when the joint between these bones, the distal radioulnar joint (or DRUJ), is unstable. When the DRUJ is unstable, the ulnar styloid may require independent treatment.
The fracture is usually a hairline fracture, commonly missed on normal X-rays. Symptoms are pain aggravated by gripping, tenderness over the hamate and symptoms of irritation of the ulnar nerve. This is characterized by numbness and weakness of the fifth digit with partial involvement of the fourth digit as well, the "ulnar 1½ fingers".
Olecranon fracture is a fracture of the bony portion of the elbow.The injury is fairly common and often occurs following a fall or direct trauma to the elbow. The olecranon is the proximal extremity of the ulna which is articulated with the humerus bone and constitutes a part of the elbow articulation.
