Utilisation of the minimally invasive chevron akin (mica) osteotomy for severe hallux valgus: a systematic review

BACKGROUND AND AIM

Hallux valgus is the most common forefoot disease that can cause pain and be disabling for the patient. Many surgical procedures have been described to correct this deformity; over the last years, the minimally invasive Chevron and Akin osteotomies (MICA) technique has become very popular. The aim of this review was to assess if MICA technique is a reliable procedure for treating severe hallux valgus.

METHODS

A systematic review was performed according to the Preferred Reporting Items for systematic Reviews and Meta-Analysis (PRISMA) guidelines. The keywords were searched in PubMed Medline and Cochrane library. To minimise the number of missed studies, no filters were applied to the search strategy. To be considered for this review, the articles needed to comply with the following inclusion criteria: Minimally invasive Chevron and Akin osteotomy (MICA) for severe hallux valgus (HVA > 40°, IMA > 16°), patient age over 18 years and minimum follow-up of 6 months.

RESULTS

Following the PRISMA flow chart 7 studies met the inclusion criteria and were taken into consideration in the review. We reached a population of 582 patients for a total of 676 feet. Males and females were 64 and 518, respectively. The mean age was 54.15 ± 8.25. The mean follow-up was 23.74 ± 9.60 months. All the studies reported an improvement in clinical results, in terms of function and quality of life. Radiological variables, mostly IMA and HVA, assessed pre- and postoperatively showed significant improvement in all studies included.

CONCLUSIONS

Despite the limited number of published studies in the literature, the available evidence reveals good clinical outcomes and high levels of patient satisfaction. Percutaneous surgery for severe hallux valgus can achieve great deformity correction with reasonable rates of residual deformity. Patient satisfaction and quality of life following third-generation MICA surgery is very high.

SERI Technique for Isolated Juvenile Hallux Valgus Patients: A Retrospective Evaluation With Mid-term to Long-term Follow-up

INTRODUCTION

Many different operative procedures have been described to treat hallux valgus, but many of them are inappropriate for active, skeletally immature patients. This retrospective evaluation aimed to show the efficacy of SERI (Simple, Effective, Rapid, Inexpensive) technique in young patients affected by mild to moderate hallux valgus deformity at a mid-term to long-term follow-up.

METHODS

All patients were clinically and radiographically evaluated, independently by 2 researchers, by American Orthopaedic Foot and Ankle Society (AOFAS) Hallux-Metatarsophalangeal-Interphalangeal score and radiographic examination.

RESULTS

Twenty-nine feet, undergone SERI procedure, have been reviewed at a mean follow-up of 5 years. The mean AOFAS score was significantly improved from 59.7 preoperatively to a mean value of 90.7 at last follow-up. Mean correction degrees have been recorded for both angles (hallux valgus angle [HVA] -13.7° and intermetatarsal angle [IMA] -6.7°).

CONCLUSIONS

The SERI technique represents a powerful surgical procedure for the treatment of painful, mild to moderate, juvenile hallux valgus. Recurrence and complication rate make this surgical approach effective, repeatable, and safe.

Influence of Foot Type on the Clinical Outcome of Minimally Invasive Surgery for Metatarsalgia. A Prospective Pilot Study

Background and aims: Surgical procedures for central metatarsalgia seek to harmonise the metatarsal parabola with osteotomies that can be performed by minimally invasive techniques. However, the possible relationship of the foot type and the mid-term postoperative outcome is poorly described. The objective of this prospective pilot study was therefore to determine whether the foot type (pronate, neutral, or supinate) conditions the postoperative mid-term functional outcome.

Methods: A series of 28 patients (6 men, 22 women) were treated for primary central metatarsalgia by means of minimally invasive distal metaphyseal osteotomy (DMMO).

Results: Their functional outcomes at 6 and 12 months were assessed by the self-reporting AOFAS scale. Pre-surgery, the patients' scores were 42.82 ± 15.60. Scores improved at 6 months to 86.50 ± 8.6 and to 92.93 ± 8.6 at 12 months (p < 0.001 in both cases). There were no differences either by sex or by foot type in these overall values, although there was only a slight limitation of interphalangeal mobility in the supinated feet (p = 0.03) at 6-month follow-up as compared to other foot types.

Conclusion: Hence, DMMO provides an optimal clinical and functional outcome for the surgical treatment of metatarsalgia, regardless of the patient's foot posture. The occurrence of adverse events was minimal and clinically irrelevant.

Trial registration: The study was authorised by the Research Ethics Committee of the Universidad Católica de Valencia San Vicente Mártir, with the registry UCV/2018-2019/019.

Long Term Clinical-Functional and Ultrasound Outcomes in Recreational Athletes after Achilles Tendon Rupture: Ma and Griffith versus Tenolig

Background and Objectives: The purpose of this retrospective study was to compare the long-term clinical-functional and ultrasound outcomes of recreational athletes treated with two percutaneous techniques: Ma and Griffith (M&G) and the Tenolig technique (TT). Materials and Methods: recreational athletes, between 18 and 50 years of age, affected by acute Achilles tendon rupture (AATR), treated by M&G or Tenolig techniques were recruited. Clinical-functional outcomes were evaluated using Achilles Tendon Rupture Score (ATRS), AOFAS Ankle-Hindfoot score, VAS (for pain and satisfaction) questionnaires, and ultrasound analysis (focal thickening, hypoechoic areas, presence of calcifications, tendinitis and alteration of normal fibrillar architecture). Results: 90 patients were included: 50 treated by M&G, 40 by TT. In all, 90% of patients resumed sports activities, with pre-injury levels in 56% of cases after M&G and in 60% after TT. In the M&G group, the averages of the questionnaires were ATRS 90.70 points, AOFAS 91.03, VAS satisfaction 7.08, and VAS pain 1.58. In the TT group: ATRS 90.38 points, AOFAS 90.28, VAS satisfaction 7.76, and VAS pain 1.34. The TT group showed a significantly higher satisfaction and return to sport activities within a shorter time. In the M&G group, ultrasound check showed a significantly greater incidence of thickening and an alteration of fibrillar architecture in the treated tendon. Three infections were reported, including one deep after M&G, two superficial in the TT group, and two re-ruptures in the Tenolig group following a further trauma. Conclusions: At long-term follow-up, M&G and TT are both valid techniques for the treatment of AATRs in recreational athletes, achieving comparable clinical-functional results. However, TT seems to have a higher patient satisfaction rate, a faster return to sports and physical activities, and fewer ultrasound signs of tendinitis. Finally, the cost of the device makes this technique more expensive.

Sport Ability during Walking Age in Clubfoot-Affected Children after Ponseti Method: A Case-Series Study

BACKGROUND

The Ponseti method (PM) of manipulative treatment for congenital talipes equinovarus (CTEV) or clubfoot became widely adopted by pediatric orthopedic surgeons at the beginning of the mid-1990s with reports of long-term successful outcomes. Sports are crucial for children's development and for learning good behavior. This study aimed to evaluate the sports activity levels in children treated with PM and to assess the different outcomes, according to gender and bilaterality.

METHODS

A total of 25 patients (44 feet) with CTEV treated by the PM were included in the study. The patients were clinically evaluated according to the Clubfoot Assessment Protocol, American Orthopedic Foot and Ankle Society, Ankle-Hindfoot score, the Foot and Ankle Disability Index (CAP, AOFAS, and FADI, respectively), and FADI Sport scores.

RESULTS

The overall mean CAP, AOFAS, FADI, and FADI Sport scores were 97.5 ± 6.4 (range 68.75-100), 97.5 ± 5.8 (range 73.00-100), 99.9 ± 0.6 (range 97.1-100), and 100, respectively. Gender and bilaterality did not affect outcome (p > 0.05).

CONCLUSIONS

The data confirmed good-to-excellent outcomes in children with CTEV managed by PM. No limitations in sport performance or activity could be observed. In particular, male and female patients and patients with unilateral or bilateral involvement performed equally well.

Translation, cross-cultural adaptation, reliability, and validation of the italian version of the Foot and Ankle Disability Index (FADI)

BACKGROUND AND AIM OF THE WORK

Foot-and-Ankle-Disability-Index (FADI) is one of the most widely used evaluation questionnaires for this anatomical district, but an italian validated version lacks and is necessary to properly evaluate italian people. In fact a correct interpretation of the items by patients is essential to obtain a precise subjective response, making the questionnaire valid to evaluate patients' satisfaction and wellness. Our purpose was to translate and culturally adapt into Italian the FADI questionnaire, and to check its reproducibility and validity.

MATERIALS AND METHODS

The original english version of FADI questionnaire was translated into Italian and checked for medical part coherence. It was submitted to 10 italian randomized patients to verify a correct cultural adaptation, and then to other 50 randomized patients operated at their ankle or hallux to assess intra- and inter-observer reproducibility by the Pearson's-Correlation-Coefficient (PCC) and the Intra-Class-Correlation (ICC) coefficient. Moreover, Short-Form-36 (SF36) questionnaire for Quality-of-Life and Visual-Analogue-Scale (VAS) for pain were also administered to the same 60 people and compared to italian-FADI to perform validation analysis by PCC and ICC coefficient.

RESULTS

Cultural adaptation of the translated version of the scale resulted good in terms of understandability by patients. An optimal correlation of the inter- and intra-observer reproducibility was obtained. The correlation obtained between FADI and SF-36 as well as between FADI and VAS indicates success in the validation process.

CONCLUSIONS

Validation of the FADI italian version has been performed successfully, its use can be considered appropriate and is indicated in italian clinical practice. (www.actabiomedica.it).
