In this technical report study, we describe technique for performing the osteotomy and screw passage in minimally invasive fourth-generation hallux valgus surgery with transverse and akin extra-articular metaphyseal osteotomy (META) using a 3D-printed patient-specific surgical instrumentation guide. In an effort to minimize the learning curve and address the variability associated with technical corrections and screw placement, we have initiated the creation of personalized patient-specific…

CONCLUSION: Using Ilizarov equipment for distraction osteogenesis of MT1 is a low-cost and effective method. Over time, this technique has proven its utility in pronounced iatrogenic shortening of MT1. The possibility to lengthen more than 1 cm, to correct in multiple planes, as well as early mobilization and weight bearing are additional advantages, but one must be careful to avoid overcorrection. The need for strict follow-up with multiple radiographs and rigorous patient selection is…

The revival of “new” minimally invasive bunion surgery (MIBS) is made possible as a laparoscopic-like fluoroscopically guided procedure using new instrumentation, advanced osseous realignment techniques and procedure-specific orthopedic hardware. Bunions of all severities can be treated with MIBS with a functional walking recovery in a small surgical shoe. Realignment occurs through a subcapital osteotomy with metatarsal head shifts that are stabilized by a single or dual metatarsal MIBS…

Visual AbstractThis is a visual representation of the abstract.

Background/Objectives: Hallux valgus, or a bunion, is a prevalent foot deformity associated with pain, limited mobility, and reduced quality of life. Surgical treatments include minimally invasive and traditional open techniques, but the optimal approach remains debated. This systematic review evaluates long-term outcomes, patient satisfaction, cost-effectiveness, the influence of patient-specific factors, rehabilitation protocols, and complication rates for these methods. Methods: A…

CONCLUSION: An average of 35.5 surgeries (range 27 – 40) are needed to reach the plateau phase for MIS for HV. The learning phase of the learning curve of MIS for HV has a significant increase in OR time and fluoroscopy usage. However, the learning phase of the learning curve of MIS for HV is not associated with decreased outcomes or higher complication rates based on the small sample size in this study.

Background: Hallux valgus is a prevalent foot deformity conventionally treated with open surgical techniques, which carry risk of complications due to extensive soft tissue dissection. Minimally invasive surgeries (MISs) as alternatives offer comparable outcomes, reduced pain, and faster recovery; however, their challenges include the risk of shortening of the first metatarsal. This study aimed to assess the efficacy of our modified MIS hallux valgus correction technique and investigate the…

CONCLUSION: This preliminary classification provides a reliable tool for assessing first metatarsal bone healing following MIS hallux valgus osteotomies, with substantial interobserver reliability. It offers a standardized approach for radiographic evaluation, which may enhance comparability across studies and serve as a radiographic research tool pending further validation. Its clinical applicability remains to be determined.

CONCLUSION: The mFI-5 was not useful to predict postoperative complications and reoperations after hallux valgus corrective surgery. Therefore, other factors should be considered when analyzing the risk of complications after HV corrective surgery.

CONCLUSIONS: RHVC increases with increasing age and occurs commonly in female teens. The recent RHVC in Japan was lower than that reported in Europe and the United States, with an increasing trend among elderly people.

CONCLUSIONS: A joy-stick assistant three-dimensional modified technique is proposed to control the three-dimensional position of the metatarsal head and to reduce dependence on special tools. Mild and moderate hallux valgus deformities are effectively corrected using Joy-stick 3D technique.

CONCLUSION: This study validated a simulation model and training program, allowing nonexperienced HV MIS foot and ankle surgeons to enhance their surgical proficiency and effectively complete a substantial portion of the learning curve at the fifth session, and this performance was successfully transferred to a cadaver model.

CONCLUSIONS: the RSS seems to provide more comfort to the patients without worsening the radiological results.

CONCLUSION: MIS for the treatment of hallux valgus using the Shannon burr appears to be a safe and effective therapy, with appropriate correction of the hallux valgus deformity, improvement in functional outcomes, high patient satisfaction, low recurrence, and acceptable complication rates.
