Hypothesis
Does a single dose of cross-linked hyaluronic acid improve the range of mobility of the first metatarsophalangeal joint?
Conclusion
The study found that injecting cross-linked hyaluronic acid significantly improved the range of motion in the first metatarsophalangeal joint without causing damage to surrounding structures.
Supporting Evidence
- The study showed a significant increase in loaded dorsiflexion from 47° to 58°.
- Unloaded dorsiflexion also improved from 41° to 58° after treatment.
- No injuries to anatomical structures were observed during the study.
Takeaway
This study shows that a special gel can help a stiff toe move better without hurting the surrounding parts.
Methodology
Ten fresh frozen feet were injected with cross-linked hyaluronic acid, and their range of motion was measured before and after the procedure.
Potential Biases
Potential bias in sample selection and the off-label use of the product.
Limitations
The study used cadaveric specimens, which may not fully represent living patients.
Participant Demographics
4 men and 6 women, average age 87.5 years.
