Summary
A novel surgical technique addresses snapping hamstring tendons in patients with hypermobility syndrome. This method involves tenotomy and tendon transposition, preserving hamstring muscle function and strength.
Area of Science:
- Orthopedic Surgery
- Sports Medicine
- Biomechanical Engineering
Background:
- Snapping hamstring tendons, often associated with hypermobility syndrome, can cause significant discomfort and functional limitation.
- Traditional surgical interventions like tenotomy or tendon harvest may compromise muscle function.
Observation:
- A 14-year-old female with hypermobility syndrome experienced bilateral snapping of the semimembranosus (SM) and semitendinosus (ST) tendons.
- Conservative management failed, necessitating surgical intervention.
Findings:
- A two-stage surgical approach was employed: tenotomy of the SM tendon followed by transposition of the ST tendon to the gracilis tendon.
- This technique aims to maintain hamstring muscle length, strength, and overall function post-operatively.
Implications:
- This innovative technique offers a viable alternative for managing snapping hamstring tendons, particularly in cases of hypermobility.
- Preserving muscle function through tendon transposition represents a significant advancement in surgical outcomes for this condition.
