Explanation:Supracondylar fractures of the humerus in children are strongly associated with compartment syndrome of the forearm. The injury mechanism often involves severe soft tissue swelling and vascular compromise. Associated brachial artery injury can worsen ischemia. Early warning signs include increasing pain, tense swelling, and pain on passive finger extension. Prompt recognition and fasciotomy are critical to prevent Volkmann ischemic contracture. Vigilant postoperative monitoring is essential in these cases. Reference: Mubarak SJ. "Compartment Syndromes in Children." Journal of Pediatric Orthopaedics, 1981.
