First metatarsophalangeal fusion using joint specific dorsal plate with interfragmentary screw augmentation: Clinical and radiological outcomes

Background

This study reports the outcome of a plating system for arthrodesis of the first metatarsophalangeal joint (1st MTPJ) that incorporates a lag compression screw within a low profile titanium plate with a predetermined contour. This is the first report of the outcomes of this implant from a non-affiliated centre.

Patient and methods

This is a prospective cohort study of 40 consecutive primary 1st MTPJ arthrodesis procedures. The mean age of the cohort was 56 years (range, 20–74 years). The diagnosis was hallux rigidus in 31 patients and inflammatory arthropathy in 7 patients.

Results

All patients achieved clinical union at 6 weeks and radiological union was confirmed on plain radiographs between 6–16 weeks. One case of hardware removal was reported.

Conclusion

The cohort achieved consistently satisfactory results with a reliable and reproducible MTPJ position and a 100% union rate. There was a low rate of hardware removal.

Level of evidence

Level IV evidence. Prospective cohort study.
