Purpose of the study: Minimally invasive techniques are gaining popularity. We report our experience with the treatment of hallux valgus using a hybrid technique combining wedge osteotomy of M1 and other procedures (arthrolysis, phalangeal osteotomy) performed percutaneously.

Material and methods: This was a prospective consecutive series of 172 operated feet in 139 patients, mean age 2005 to 2007. All procedures were performed by the same operator and reviwed by an independent observer at mean maximum follow-up of 18 months. The same operative technique was used; the only variable was Akin osteotomy performed (in 67%) or not, fixed (one out of three) or not. Assessment compared pre and postoperative values for the angles M1M2, M1P1, DMAA and DM2AA, joint range of motion, Kitaoka score and morbidity.

Results: At maximum follow-up, the independent observer noted: 40.6% and 71% improvement in M1M2 and M1P1 angles, 42.3% in DMAA and 122% in DM2AA, 32.3% in the P1P2 angle, and 71.8% in the Kitaoka score. Dorsiflexion was diminished 4.2%, plantar flexion 19.6%. Material was removed in 7%, and complication rate was 2.9%; there were no deep infections. The procedure was achieved in an outpatient setting from 57% of patients. Excepting one patient who was disappointed, all other patients were satisfied or very satisfied with their operation.

Discussion: Wedge osteotomy is an attractive first-intention procedure for the treatment of moderate hallux valgus. It is even more so when combined with the academic percutaneous surgery imported in France by GRECMIP indicated in a still limited number of situations. All parameters are significantly improved with a perfectly controlled morbidity. The absence of deep infection despite (or thanks to) refection 15 days after the first dressing is particularly noteworthy. This method has the approval of nearly 100% of patients and presents many advantages: absence of pain related to unwonted mobilization during wound care, maximal protection of the operated foot in the dressing which is humid at first then hardens forming a shock absorber without extra cost for the postoperative care.

Conclusion: We validate this concept which constitutes a fundamental progress in forefoot surgery, particularly in phase with the current concern for cost containment.
