Aims. The aim of this study was to report a single surgeon series of
consecutive patients with moderate hallux valgus managed with a
percutaneous extra-articular reverse-L chevron (PERC) osteotomy. . Patients and Methods. A total of 38 patients underwent 45 procedures. There were 35
women and three men. The mean age of the patients was 48 years (17
to 69). An additional percutaneous Akin osteotomy was performed
in 37 feet and percutaneous lateral capsular release was performed
in 22 feet. Clinical and radiological assessments included the type
of forefoot, range of movement, the American Orthopedic Foot and
Ankle (AOFAS) score, a subjective rating and radiological parameters. . The mean follow-up was 59.1 months (45.9 to 75.2). No patients
were lost to follow-up. Results. The mean AOFAS score increased from 62.5 (30 to 80) pre-operatively
to 97.1 (75 to 100) post-operatively. A total of 37 patients (97%)
were satisfied. At the last follow up there was a statistically
significant decrease in the hallux valgus angle, the intermetatarsal
angle and the proximal articular set angle. The range of movement
of the first metatarsophalangeal joint improved significantly..
There was more improvement in the range of movement in patients
who had fixation of the osteotomy of the proximal phalanx. Conclusion. Preliminary results of this percutaneous approach are promising.
This technique is reliable and reproducible. Its main asset is that
it maintains an excellent range of movement. Take home message: The PERC osteotomy procedure is an effective
approach for surgical management of moderate hallux valgus which
combines the benefits of
