First Metatarsophalangeal Joint (MTPJ) Arthrodesis for Hallux Values: Key Findings

For severe hallux values deformity, MTPJ arthrodesis offers definitive correction, but outcome data is sparse.

The study

A single-center retrospective case series between 2016–2021, reviewed 62 feet with a mean preoperative hallux valgus angle of 40.2° and intermetatarsal angle of 15.9°.

• Researchers found that patient-reported outcomes improved significantly by 26 weeks. 

• Foot function composite scores (MOxFQ) improved by 33.0 points.

• Quality-of-life scores (EQ5D time trade-off) improved by 0.217 points (P < .001).

• Improvements were sustained at two years, postoperatively.

The concern

Nearly one in five patients experienced complications: 

• 9.7% non-union rate

• 11.3% reported persistent pain

• 4.8% required later hardware removal

First MTPJ arthrodesis delivers durable, measurable functional gains, but clinicians must weigh a clinically significant complication burden in preoperative planning and informed consent.
