Purpose:
There is growing evidence supporting minimally invasive surgical (MIS) techniques for correction of symptomatic hallux valgus. The aim of this study was to present a hybrid third-generation technique and assess the safety and efficacy from the first 45 procedures.
Methods:
Forty-five consecutive feet underwent a third-generation MIS distal chevron osteotomy with a minimum six month follow-up (range six to 17 months). This technique uses both first- and second-generation techniques plus a distal chevron osteotomy and screw for improved control and stabilisation of the metatarsal head. All patients were clinically assessed using the Manchester-Oxford Foot Questionnaire (MOXFQ). Radiographic measures included hallux valgus angle (HVA), intermetatarsal angle (IMA), first metatarsal length and overall toe length.
Results:
There were significant improvements in all three domains of the MOXFQ (p <0.001). There was also significant improvement in all radiographic parameters (p < 0.001). Mean HVA decreased from 30.54° to 10.41°, and the mean IMA decreased from 14.55° to 7.11°. Shortening of the first metatarsal had no effect on clinical outcomes. There was a very low rate of complications.
Conclusion:
The short-term results of this third-generation technique show that it is a safe procedure with good clinical outcomes and compares favourably with earlier techniques.
