Insights
Trigger-hallux involves flexor hallucis longus tendon thickening and rupture. Simple surgical division of the retinaculum flexorum effectively treats this condition, preventing further degeneration.
Area of Science:
- Orthopedics
- Podiatry
- Sports Medicine
Background:
- Trigger-hallux, or stenosing tenosynovitis of the hallux, is characterized by inflammation and thickening of the flexor hallucis longus tendon.
- Pathological changes include partial rupture of central tendon fibers proximal to the tarsal tunnel, impeding smooth tendon gliding.
Observation:
- A case study of an 11-year-old girl with trigger-hallux is presented.
- The patient exhibited characteristic symptoms and imaging findings consistent with the condition.
Findings:
- Surgical division of the retinaculum flexorum was performed.
- This procedure allowed for free tendon movement, alleviating mechanical obstruction.
Implications:
- The simple surgical intervention effectively resolved trigger-hallux symptoms in the patient.
- This approach prevents further tendon degeneration and offers a promising treatment for pediatric trigger-hallux.
Abstract:
Characteristic for a trigger-hallux is a thickening of the m. flexor hallucis longus tendon combined with partial rupture of the central fibers proximal to the tarsal tunnel. Division of the retinaculum flexorum leads to free tendon movement and prevents further tendon degeneration. The course of an 11-years old girl is reported. An effective treatment is established by a simple surgical procedure.
