Eligibility Criteria

Inclusion

  • Age: 10 to 45 years old.
  • Clinically and molecular genetically confirmed diagnosis of hereditary spastic paraparesis (HSP) with either isolated Achilles tendon contracture or equinovarus cavus deformity.
  • Radiographic (X-ray) or computed tomography (CT) evidence confirming the presence of isolated Achilles tendon contracture or equinovarus cavus deformity.
  • Signed informed consent form by patients/legal guardians for voluntary participation in the clinical study, with full comprehension of and commitment to study protocols .
  • Suboptimal response to standard conservative treatments (pharmacotherapy and/or rehabilitative exercise programs) with progressive worsening of gait abnormalities and foot deformities .
  • Functional impairment secondary to isolated Achilles tendon contracture or equinovarus cavus deformity, manifesting as ambulatory pain, frequent falls, and significant quality-of-life limitations.
  • Ability to ambulate barefoot for 10 meters independently or with assistive devices.

Exclusion

  • Prior history of foot and ankle orthopedic surgery.
  • Severe cognitive impairment or an inability to adhere to postoperative protocols and functional assessments.
  • Isolated Achilles tendon contracture or equinovarus cavus deformity resulting from definitive etiologies (e.g., diabetes mellitus, infectious arthritis, or inflammatory arthropathy).
  • Significant peripheral vascular disease or clinically significant unstable medical conditions, including malignancies, hematologic disorders, and cardiopulmonary, hepatic, or renal insufficiency.
  • Coexisting neurodegenerative or neuromuscular disorders that are unrelated to hereditary spastic paraplegia (HSP).
  • Poor compliance with study requirements or other contraindications to participation in clinical trials.
