Hamstring Syndrome refers to compression of which neural structure?

• A. Femoral nerve
• B. Obturator nerve
• C. Tibial nerve
• D. Sural nerve

Answer: (C)

Hamstring syndrome is about a nerve getting pinched in the posterior thigh as it runs with the hamstring tendons. The tibial portion of the sciatic nerve is the structure most commonly compressed here, especially where the nerve travels near the ischial tuberosity or beneath tight hamstring tissue. Repetitive hamstring loading or scar tissue from prior injury can create a constriction that produces posterior thigh pain with neural signs that can mimic a hamstring strain. The other nerves listed don’t fit this pattern: those paths would cause problems in different regions (femoral in the anterior thigh, obturator in the medial thigh, or distal sensory signs in the foot with the sural nerve). So, the tibial nerve is the nerve most commonly involved in hamstring syndrome.
