Guided Percutaneous Hallux Valgus Surgery: Advancing Into the Future With the Fourth-Generation Technique. Outcomes...

BackgroundThe aim of this study is to describe the surgical technique, outcomes, and complications associated with fourth-generation percutaneous hallux valgus correction using a guided system.MethodsProspective case series of 28 patients, aged 16 and older (5 men and 23 women), averaging 56.89 years, who underwent surgery for hallux valgus with at least 12 months of follow-up.ResultsThe preoperative American Orthopaedic Foot & Ankle Society (AOFAS)-hallux score increased from 63.8 to 89.7 (P < .001) at 12 months post-surgery. The visual analog scale (VAS) score decreased from 6 to 0.16 (P < .001) in the same period. The preoperative intermetatarsal angle (IMA) decreased from 13.38° to 2.72° (P < .001) post-surgery, while the Hallux valgus angle (HVA) decreased from 23.01° to 5.2° (P < .001). There were 3 complications including 1 superficial wound infection, 1 malpositioning of the screws and 1 hypertrophic non-union.ConclusionThe described percutaneous hallux valgus surgery appears to be reliable, with consistent improvements in clinical outcomes and radiological results. The guided technique is promising in order to reduce common complications.Level of Evidence:Level IV, prospective case series.
