Hamstring tightness in adolescents with lumbar disc herniation may stem from a different cause than sciatic pain. CT myelography revealed nerve root displacement without swelling in tight hamstrings, unlike compressed roots in sciatica.

Area of Science:

  • Neurology
  • Radiology
  • Orthopedics

Background:

  • Lumbar disc herniation is a common cause of back and leg pain in adolescents.
  • Understanding the underlying mechanisms of associated symptoms like hamstring tightness is crucial for accurate diagnosis and treatment.

Observation:

  • Thirty-six patients aged 11-19 with lumbar disc herniation were evaluated using CT myelography.
  • Patients were divided into two groups: Group A (six patients) with isolated hamstring tightness and no sciatica, and Group B (30 patients) with sciatic pain.

Findings:

  • CT myelography showed posterior displacement but no nerve root swelling in Group A patients.
  • In contrast, 21 Group B patients exhibited nerve root swelling and compression between the herniated disc and superior articular process.

Implications:

  • Hamstring tightness in this population may arise from a distinct pathophysiological mechanism compared to sciatic pain.
  • These findings suggest that isolated hamstring tightness in adolescents with lumbar disc herniation warrants a different diagnostic approach.
