Neurogenic calf hypertrophy can occur due to spinal nerve injury, like S-I radiculopathy. This condition may resolve with conservative treatment, suggesting a link to muscle fiber changes.

Area of Science:

  • Neurology
  • Orthopedics
  • Muscle Physiology

Background:

  • Calf enlargement typically indicates venous thrombosis, hemorrhage, myositis, or tumors.
  • Isolated muscle hypertrophy can signal nerve injury, affecting calf muscles primarily.

Observation:

  • Three cases of S-I radiculopathy resulting in ipsilateral neurogenic calf hypertrophy after herniated nucleus pulposus are presented.
  • Patients included two males (79, 78 years) and one female (46 years).

Findings:

  • Neurogenic calf hypertrophy, though rare, was observed in patients with S-I radiculopathy.
  • Symptoms showed gradual improvement with time and conservative management.

Implications:

  • The findings suggest a potential pathogenesis involving partial denervation atrophy and compensatory hypertrophy of remaining muscle fibers.
