Fractures and Bone Healing

The ulna is one of the main bones found in the forearm together with the radius. Isolated ulna fractures commonly happen when the forearm received a direct blow like a hit from a hard object. Based from hospital records, men are more prone to ulna fractures than women because of their tendency to participate in sports and strenuous activities, which can cause damage to the forearm bones. Also known as nightstick fractures, these injuries can happen on the subcutaneous border of the ulna bone. Types of Ulna Fractures Ulna bone injuries can also be termed as stress fractures or Monteggia fractures. • Ulna Stress Fractures are the result of repetitive stress on the ulna bone creating hairline cracks, which can worsen into fractures when not immediately treated. • Monteggia Fractures are due to injuries on the proximal part of the ulna bone which are commonly connected with the bone of the radial head and suffer dislocation. Diagnosis In diagnosing ulna injuries, a physical examination is ...

The forearm has two large bones– the radius and the ulna. While the radius is larger than the ulna and it is located in the front side of the arm, it is also prone to fractures. The end point of the radius that is near the wrist is the distal end so when there is a fracture on the wrist there could also be a fracture of the distal radius. A distal radius fracture is a bone fracture that happens during a fall, with an outstretched arm and because the fracture happens very near to the wrist joint. Radius Fracture Types There are four types of distal radius bone fracture and these are the following: • Colles’ fracture . This is a distal fracture of the radius located in the forearm and dorsal end of the wrist and usually involves displacement of the wrist bone. This is also called “dinner fork deformity” because of its shape like a fork when fractured. It can be caused by falling with an extended arm. • Smith’s fracture. This is the reverse type of Colles’ fracture and this is a fracture...
