Purpose: This study evaluated the results of two groups?the early group and midterm group?comparatively in the treatment of hallux valgus using a scarf osteotomy.
Materials and Methods: From January 2005 to December 2009 (Group 1) and from January 2010 to December 2013 (Group 2), this study compared hallux valgus cases treated by a scarf osteotomy by a single surgeon with at least a five-year follow-up.
Results: The average ages of Group 1 and Group 2 were 50.5 and 51.7 years old, respectively. The average follow-up of Groups 1 and 2 were 7.4 and 6.2 years, respectively. Groups 1 and 2 had 86 cases (53 patients) and 93 cases (64 patients) with at least a five-year follow?up, respectively. The average hallux valgus angle (HVA) and 1-2 intermetatarsal angle (IMA) of Group 1 were improved from 31.3° and 13.9° preoperatively to 11.3° and 6.8° at the final follow-up, respectively (p<0.001). The average HVA and 1-2 IMA of Group 2 were improved from 31.7° and 13.4° preoperatively to 8.9° and 6.6° at the final follow-up, respectively (p<0.001). The mean American Ortho?paedic Foot and Ankle Society (AOFAS) score of both groups increased from 48.5 and 45.0 points preoperatively to 73.7 and 82.4 points at the final follow-up, respectively. The numbers of patient-assessed subjective satisfaction of Groups 1 and 2 at the final follow-ups were as follows: excellent, 27 and 36 (31.4%, 38.7%); good, 34 and 49 (39.5%, 52.7%); fair, 13 and 5 (15.1%, 5.4%); poor, 12 and 3 (13.9%, 3.2%); respectively. Neither troughing nor stress fractures occurred in both groups.
Conclusion: Scarf osteotomy for treating hallux valgus is an excellent surgical method with a relatively low incidence of complications. The results in Group 2 were better than n those in Group 1, showing that more surgical experience and evolution of the techniques provided better results.
