ABSTRACT
Hallux valgus is a prevalent condition. Many open surgical methods of correction have been described. We performed a percutaneous, extra-articular distal metatarsal osteotomy for mild to moderate bunion deformity. The minimally invasive technique was used in 217 feet (180 patients; age 49 ± 4.7 years, mean ± standard deviation) at 4 centers in North America (Center 1 November 2012 to March 2017; Center 2 January 2010 to May 2016; Center 3 October 2013 to June 2016; Center 4 January 2015 to June 2017). The procedure was used in simultaneous bilateral cases in 28 patients (15.6%) and in nonsimultaneous bilateral cases in 9 patients (5.0%). Immediate postoperative weightbearing was used in all cases. The mean preoperative intermetatarsal angle, hallux abductus angle, and tibial sesamoid position were 14.6° ± 3.5°, 30.7° ± 7.8°, and 5.4 ± 1.4, respectively. At final follow-up of 9.3 ± 6.1 months, the mean intermetatarsal angle, hallux abductus angle, and tibial sesamoid position were 4.7° ± 2.8°, 8.4° ± 6.1°, and 2.0 ± 1.0, respectively (p < .0001 for all comparisons). No major complications were noted. All 217 osteotomies achieved union; 3 feet (1.4%) in 3 patients (1.7%) experienced asymptomatic malunion. Superficial pin-site infection was seen in 42 (19.4%) of the 217 feet (39 patients, 21.7%). The radiographic results of this percutaneous technique appear to be reproducible across multiple centers, and the technique is useful when correcting intermetatarsal and hallux abductus angles. This percutaneous osteotomy for realignment of the first ray allows immediate postoperative weightbearing and, in this initial review, appears to be safe and effective, even in simultaneous bilateral cases.
