MIAA vs . SERI Minimally Invasive HAV Correction: A Retrospective Comparative Single Surgeon Study in a Rural Area

Don T Peacock and Fellner D

Objective: The objective of this research is to compare two minimally invasive bunion procedures scientifically. The Null Hypothesis states there is no significant difference in outcomes between the two methods. The research tests the validity of this hypothesis.

Methods: A total of 50 consecutive feet (50 patients) with mild to moderate hallux valgus deformity were part of the study (hallux valgus ≤ 37 degrees and inter-metatarsal angle ≤ 20 degrees). Twenty-five patients had the minimally invasive Austin Akin procedure, and 25 had the Simple Effective Reliable, Inexpensive method. All patients followed for six months post-operatively. Visual analog scores recorded on pre-op, two weeks, four weeks, six weeks, and six months. Subjective and objective results recorded preoperatively and at six months.

Results: The minimally invasive Austin Akin group showed significantly lower visual analog scores at postoperative 6 weeks (P<0.040). Both groups showed improved American Orthopedic Foot and Ankle Society Hallux metatarsophalangeal score at post-op 6 months (minimally invasive Austin Akin group: 48.8 to 92.6, Simple Effective Reliable Inexpensive group 45.6 to 92.4, P=0.970). In both groups 19 patients (76%) reported excellent results. Significant improvement in inter-metatarsal angle and hallux valgus angle in both groups (P=0.469 and P=0.136, respectively).

Conclusion: Both techniques obtained correction of mild to moderate hallux valgus with similar radiological measurement outcomes at six months. However, the minimally invasive Austin Akin group had significantly less pain at six weeks.
