Colle's fracture refers to the fracture of?

Appeared in: Daman & Diu Staff Nurse - 2018

Explanation

  • Colles' fracture is specifically defined as a fracture of the distal portion of the radius.
  • This injury is very common and typically results from a fall onto an outstretched hand (FOOSH).
  • The force of the fall causes the distal fragment of the radius to be displaced dorsally (posteriorly), leading to a characteristic 'dinner-fork' deformity.
  • The radius is the larger of the two forearm bones and is a primary weight-bearing bone, making it susceptible to this type of fracture.

Why Other Options Were Wrong

  • Option A: The ulna is the other bone in the forearm, located on the medial side (pinky finger side). While it can be fractured, a Colles' fracture specifically involves the radius.
  • Option B: The humerus is the bone of the upper arm, extending from the shoulder to the elbow. A Colles' fracture is an injury to the wrist/forearm area.
  • Option D: The olecranon is the prominent bony projection of the ulna that forms the point of the elbow. A Colles' fracture occurs at the distal end of the radius, near the wrist.

Clinical Relevance
  • Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Definition and anatomical location of a Colles' fracture as background academic context rather than a clinical decision trigger.
  • Nurses must perform frequent neurovascular checks on the affected limb post-injury and post-reduction to detect and prevent compartment syndrome, a limb-threatening emergency.
  • Patient education is crucial, focusing on cast care, signs of complications (increased pain, swelling, numbness, discoloration), and the importance of elevating the limb to control edema.
  • Colles' fractures are strongly associated with osteoporosis, making them a 'fragility fracture.' This finding should prompt the nurse to consider patient education on bone health, fall prevention, and screening for osteoporosis.
How to Approach the Question
  • Identify the core term in the question: 'Colle's fracture'.
  • Recognize this as a factual recall question that requires knowledge of orthopedic terminology.
  • Recall the definition of a Colles' fracture. It is one of the most common wrist fractures.
  • Mentally picture the anatomy of the arm and forearm: Humerus (upper arm), Radius and Ulna (forearm).
  • Associate 'Colle's fracture' with the distal radius. The olecranon is part of the ulna at the elbow, and the humerus is the upper arm bone, so these can be eliminated.
  • Select the option that correctly identifies the bone involved.
