Summary
Restoring hand grip in tetraplegia involves a two-stage surgery: first hand opening (extensor), then hand closing (flexor). Surgical timing and methods depend on the International Classification (IC) group, particularly from group 5 onwards for active extension.
Area of Science:
- Hand surgery
- Tetraplegia treatment
- Reconstructive surgery
Background:
- Restoring grip function in tetraplegia is a significant challenge.
- A staged surgical approach is crucial for optimal outcomes.
- The International Classification (IC) system guides surgical strategy.
Purpose of the Study:
- To outline a surgical strategy for restoring hand function in tetraplegic patients.
- To define the timing and specific procedures for hand opening and closing stages.
- To differentiate surgical approaches based on the International Classification (IC) groups.
Main Methods:
- A two-stage surgical approach: initial hand opening (extensor) followed by hand closing (flexor).
- Surgical strategy is stratified based on International Classification (IC) groups, with group 5 as a critical juncture.
- Passive procedures (tenodesis, arthrodesis) are used for IC groups 2-4, while active digital extension is feasible from group 5.
Main Results:
- Active digital extension becomes feasible starting from IC group 5.
- Active thumb ray stabilization is achievable in lower IC groups.
- Differentiating between supple and rigid claw deformities is essential for corrective procedures.
Conclusions:
- The surgical strategy for tetraplegic hand reconstruction hinges on the IC group.
- Restoration of active digital extension and thumb stabilization are key goals.
- Tailoring procedures to deformity type (supple vs. rigid claw) improves outcomes.
