Modified SERI technique in the treatment of hallux valgus combined with arthritis.

INTRODUCTION

Few reports encompass the treatment of first metatarsophalangeal joint (MTPJ) arthritis complicating hallux valgus. Indeed, in the literature, there is a lack of guidance concerning the management of patients affected by mild to moderate first MTPJ arthritis complicating hallux valgus. The aim of this study is to present the mid-term results of an original joint-preserving surgical technique.

MATERIALS AND

METHODS

A group of 50 patients (60 feet) affected by mild to moderate first MTPJ arthritis complicating hallux valgus who underwent modified Giannini's SERI (simple, effective, rapid, inexpensive) surgical procedure were prospectively reviewed. They were clinically and radiographically evaluated preoperatively and after surgery and were also assessed using the American Orthopedic Foot and Ankle Society (AOFAS) score and Coughlin and Shurnas classification. The average follow-up was 38 months. A multivariate analysis was performed to evaluate the existing relationship between postoperative AOFAS results and radiological preoperative measured angles and sesamoid grade of dislocation.

RESULTS

The average AOFAS score significantly improved at last follow-up to an average of 90.5 ± 14.5, while preoperatively it was 45.6 ± 15.3 ( p < 0.001). On multivariate analysis, a statistically significant correlation resulted among all the radiographic preoperative registered parameters and clinical postoperative results. However, it was shown that any radiological parameter alone could not predict a better clinical recovery.

CONCLUSIONS

The surgical technique proposed here could extend the indications of the SERI procedure to those patients affected by mild to moderate hallux valgus combined with mild to moderate osteoarthritis.
