Shin splints may present with signs suggestive of which serious condition due to compression of the deep peroneal nerve and anterior tibial artery?

• A. Osteomyelitis
• B. Tendinopathy
• C. Gout
• D. Compartment syndrome

Answer: (D)

When swelling or increased pressure builds up inside a leg muscle compartment, it can compress the structures contained in that compartment. If the anterior (shin) compartment is involved, the deep peroneal nerve and the anterior tibial artery can be compressed. This creates a clinical picture that can mimic shin splints but signals a much more serious condition: compartment syndrome. The deep peroneal nerve provides sensation between the first two toes and motor control of the muscles that dorsiflex the foot, while the anterior tibial artery supplies blood to the same compartment. Compression here leads to disproportionately severe pain, pain with passive stretching of the muscles, and sensory changes in the web space between the big toe and second toe, with potential weakness of dorsiflexion. If not addressed promptly, it can progress to muscle necrosis and nerve injury, making it a medical emergency. Osteomyelitis would present with fever and bone infection signs; tendinopathy shows tendon overuse pain at the tendon site without neurovascular compromise; gout presents as acute joint inflammation, often in the toe. The key feature here is the involvement of the deep peroneal nerve and the anterior tibial artery within the anterior leg compartment, pointing to compartment syndrome.
