Scarf osteotomy for reduction of tailors bunion deformities: Systematic review and meta-analysis.

BACKGROUND

Tailors bunions are common forefoot deformities affecting the fifth MPJ, with challenging symptomatology often resistant to conservative care. Currently no gold standard exists for the surgical management of tailor's bunions, although the scarf osteotomy has been described as a versatile option for reducing these deformities.

METHODS

Relevant electronic databases were searched to collate all studies pertaining to tailors bunion correction using the scarf osteotomy between 2000 and 2021. Both surgeon and patient reported outcomes were required to be included in the systematic review. Methodological quality assessment and risk of bias was performed for each study. Statistical analysis of outcomes and complications was measured. Four small scale case series studies met the inclusion criteria.

RESULTS

All studies demonstrated a statistically significant reduction of 4th inter-metatarsal angles, improvement in clinical and patient reported outcome measures. 15% complication rate was identified, however recurring plantar hyperkeratoses were the most frequent, with one study suggesting a relationship with Pes Cavus. All four studies demonstrated significant methodological short comings and high risk of bias.

CONCLUSION

Scarf osteotomy provides good reduction of tailors' bunion deformities, demonstrates low complication rate and high patient satisfaction. Foot and Ankle surgeons should counsel patients' accordingly on risk of recurrence where hyperkeratosis is a key complaint.
