In 30 seconds
This pilot randomized controlled trial evaluated the feasibility and clinical outcomes of bioabsorbable screws versus titanium screws in first metatarsophalangeal joint arthrodesis among 30 patients. At 24 months, mean AOFAS scores were 89.1 for titanium and 90.0 for bioabsorbable screws (p = 0.23), indicating no significant difference in functional outcomes between the two groups.
Key findings
- Mean AOFAS scores at 24 months were 89.1 for titanium and 90.0 for bioabsorbable screws (p = 0.23).
- Mean FA-VAS total scores were 1948 in the titanium group and 1914 in the bioabsorbable group (p = 0.655).
- Overall union rate was 90%, with nonunion in one titanium and two bioabsorbable patients.
- No implant-related complications or hardware removal surgeries were recorded.
Why it matters
The study suggests that bioabsorbable screws are a safe alternative to titanium screws in first metatarsophalangeal joint arthrodesis, with comparable functional outcomes. This could influence surgical choices and patient management in orthopedic practice.
