Explanation

Compartment syndrome is an orthopedic emergency where increased pressure within a fascial compartment compromises circulation and function.
It is considered the most severe complication due to its rapid onset, which can lead to irreversible muscle necrosis, nerve damage, and potential limb loss within a few hours if not treated urgently.
The condition can arise from the initial injury or as a complication of treatment, such as a cast being applied too tightly.
Early signs, especially pain out of proportion to the injury, are critical for nurses to identify to prevent permanent damage.

Option A: Osteomyelitis is a bone infection. While a serious complication, it typically develops over days and is not as immediately limb-threatening as the acute ischemia of compartment syndrome.
Option C: Nonunion is the failure of a fracture to heal. This is a long-term complication, not an acute, severe event. Search results confirm that nonunions are rare in children due to their excellent healing potential.
Option D: A contracture is the permanent shortening of muscle or joint tissues, leading to deformity and loss of motion. It is a late sequela, not an immediate, severe complication.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Complications of Pediatric Fractures as background academic context rather than a clinical decision trigger.
Nurses are at the forefront of detecting compartment syndrome. Performing frequent and meticulous neurovascular checks (assessing the 6 P's) on children with fractures, especially after casting or surgery, is a critical nursing responsibility.
Any sign of compartment syndrome, particularly escalating pain unresponsive to analgesics, must be reported to the orthopedic surgeon immediately as it constitutes a surgical emergency requiring fasciotomy.
What if? If the child's pain is suddenly relieved after a period of intense pain, and is now accompanied by numbness and inability to move the fingers or toes, this is an ominous sign. It may indicate that nerve damage has become permanent, and the window for intervention is closing rapidly. This requires immediate escalation.

How to Approach the Question

First, understand the question is asking for the 'most severe' complication. This implies looking for the condition with the most rapid onset and the highest potential for irreversible harm or loss of limb.
Evaluate each option based on its acuity (how quickly it develops) and potential outcome.
Recall or deduce that Osteomyelitis is an infection (less acute), while Nonunion and Contracture are long-term or late-stage problems.
Identify Compartment Syndrome as an acute condition involving compromised blood flow, which is a time-critical emergency.
Conclude that the condition threatening limb viability within hours (Compartment Syndrome) is the most severe immediate complication compared to those that develop over days or months.
