[Clinical effects of simple hallux valgus surgery for transfer metatarsalgia]

Objective: To analyze the clinical effects of simple hallux valgus surgery for transfer metatarsalgia. Methods: From September 2011 to November, a total of 21 patients(30 feets)with transfer metatarsalgia of hallux valgus and underwent the simple hallux valgus surgery without lateral metatarsal shortening osteotomy In Department of Orthopedics, Beijing Tongren Hospital, Capital Medical University, were enrolled in the study.The hallux valgus angle (HVA), intermetatarsal angle (IMA) , AOFAS scale and analogue score (VAS) were measured pre-operation and a half year, one year, two years after operation.The data were measured repeatedly and analyzed with analysis of variance. Results: The mean preoperative HVA changed [(39.6±9.7), (14.2±7.9), (14.8±7.9), (13.2±6.5)°] at 6 months, 1 year and 2 years follow-up; the mean IMA decreased [(13.8±4.0), (4.5±4.3), (5.8±3.9), (5.4±4.9)°] at 6 months, 1 year and 2 years follow-up(all P<0.001).63.5% of metatarsalgia cases improved, and 73.1% of painful callosities disappeared postoperatively.All the patients do not require further surgeries. The mean AOFAS for hallux , AOFAS for lesser toes and VAS were improved from 58.96 to 95.42, from 84.38 to 92.04 and from 7.5 to 1.3, respectively. All the results are statistically significant(P<0.001). Conclusion: These results suggest that a simple osteotomy of the first metatarsal provides excellent outcomes with a low rate of complications when compared with the combining lateral metatarsal shortening osteotomy.
