Background: Hallux valgus (HV) deformity is a common, potentially debilitating deformity. And evidence with high-quality for the conservative treatments of HV deformity is still required.; AIMS: To compare the effects of different conservative treatments for hallux valgus deformity by using the method of network meta-analysis.; Study Design: A systematic review and network meta-analysis of randomized controlled trials identified by searching PubMed, EMBASE, MEDLINE, OVID, and CINAHL. The included studies should have the characteristics that: (1) participants with hallux valgus deformity of any age (2) conservative treatments (3) Reported the hallux valgus (HVA), the intermetatarsal angle (IMA), the score of the Visual Analog Scale, and the score of Foot Function Index.; Results: 11 studies were included in this review. The agreement between reviewers reached a kappa value of 0.75. The results of the network meta-analysis showed that a combination of exercise and toe separator, night splints, and dry needling are most likely to be the best choice for reducing the hallux valgus angle (HVA) and intermetatarsal angle, and toe separators (with or without exercise), dry needling, and manipulation (with or without ice treatment) have advantages in improving the subjective feeling of patients.; Conclusions: Multi-disciplinary conservative treatments have a great potential for hallux valgus deformity. More research with high-quality is needed to give a comprehensive and reasonable scheme of a holistic and long-term treatment protocol.

Prospective Case Series

Background: Hallux valgus deformity consists of a lateral deviation of the great toe, metatarsus varus, and pronation of the first metatarsal. Most osteotomies only correct varus, but not the pronation of the metatarsal. Persistent postoperative pronation has been shown to increase deformity recurrence and have worse functional outcomes. The proximal rotational metatarsal osteotomy (PROMO) technique reliably corrects pronation and varus through a stable osteotomy, avoiding fusing any healthy joints. The objective of this research is to show a prospective series of the PROMO technique. Methods: Twenty-five patients (30 feet) were operated with the PROMO technique. The sample included 22 women and 3 men, average age 46 years (range 22-59), for a mean prospective follow-up of 1 year (range 9-14 months). Inclusion criteria included symptomatic hallux valgus deformities, absence of severe joint arthritis, or inflammatory arthropathies, with a metatarsal malrotation of 10 degrees or more, with no tarsometatarsal subluxation or arthritis on the anteroposterior or lateral foot radiograph views. The mean preoperative and postoperative Lower Extremity Functional Scale (LEFS) score, metatarsophalangeal angle, intermetatarsal angle, metatarsal malrotation, complications, satisfaction, and recurrence were recorded. Results: The mean preoperative and postoperative LEFS scores were 56 and 73. The median pre-/postoperative metatarsophalangeal angle was 32.5/4 degrees and the intermetatarsal angle 15.5/5 degrees. The metatarsal rotation was satisfactorily corrected in 24 of 25 patients. An Akin osteotomy was needed in 27 of 30 feet. All patients were satisfied with the surgery, and no recurrence or complications were found. Conclusions: PROMO is a reliable technique, with good short-term results in terms of angular correction, satisfaction, and recurrence. Long-term studies are needed to determine if a lower hallux recurrence rate occurs with the correction of metatarsal rotation in comparison with conventional osteotomies. Level of evidence: IV, prospective case series.

Category: Bunion Introduction/Purpose: There is a lack of quantitative studies on the progression of juvenile hallux valgus deformity. Therefore, we performed this study to estimate an annual change of radiographic indices for juvenile hallux valgus. Methods: We reviewed medical records of consecutive patients under the age of 15 with juvenile hallux valgus who underwent weight-bearing foot radiographs more than twice, and were followed over a period of one year or more. A total of 133 feet from 69 patients were included. Hallux valgus angle, hallux interphalangeal angle, intermetatarsal angle, metatarsus adductus angle, distal metatarsal articular angle, anteroposterior talo-1st metatarsal angle, anteroposterior talo-2nd metatarsal angle, and lateral talo-1st metatarsal angle were measured and were used as a study criteria. The progression rate of hallux valgus angle was adjusted by multiple factors including the use of a linear mixed model with gender and radiographic measurements as the fixed effects and laterality and each subject as the random effect. Results: Our results demonstrate that the value of hallux valgus angle on the radiographs progressed as the patients grew older. The hallux valgus angle increased by 0.8° per year (p<0.001)(Figure). The distal metatarsal articular angle also increased by 0.8 per year (p=0.003). Conversely, hallux interphalangeal angle decreased by 0.2° per year (p=0.019). Progression of the intermetatarsal angle and metatarsus adductus angle with aging were not statistically significant. There was a difference in progression of radiographic indices between older patients (≥10 years) and younger patients (<10 years). The hallux valgus angle increased by 1.5° per year (p<0.001) in younger patients, progression of the hallux valgus angle in older patients was not statistically significant (p=0.869) as children grew up. Conclusion: These results suggest that the hallux valgus angle increased in patients with juvenile hallux valgus under 10 years old, unlike the patients aged 10 or older. We believed that our results can help surgeons to determine a treatment strategy that uses the growth potential to achieve correction of deformity such as lateral hemiepiphyseodesis of the 1st metatarsal to patients with juvenile hallux valgus.

Results of biplanar chevron osteotomy performed on patients with mild-to-moderate hallux valgus deformity with an increased distal metatarsal articular angle (DMAA) are shown. The study included clinical data of 32 patients (54 feet) who had completed a 2-year follow-up, and radiological data of these 32 and other 29 patients (50 feet) for a total of 61 patients (104 feet, 53 right and 51 left). There were 59 females and two males with ages varying from 11 to 66 years. According to the AOFAS Hallux Rating, the preoperative average score (50) improved to 90 (average score after the surgery). The hallux valgus angle was improved from an average of 25° to 14°, the first intermetatarsal angle from 12° to 8° and the DMAA from 15° to 5°. At the end of treatment, 94% of patients were classified as having grade 0 or I sesamoid lateral sub-luxation. Given improvement in angles and 90% of patients satisfied with an average AOFAS postoperative score of 90, the technique seems indicated for treatment of symptomatic hallux valgus deformity with increased DMAA.

Category: Midfoot/Forefoot Introduction/Purpose: Recent studies have shown that Hallux valgus deformity can lead to transfermetatarsalgia due to an impairment and relative shortening of the first ray. During ReveL osteotomy the relative shortening of the MT I is not addressed. Furthermore, a posterior deviation of the osteotomy angle results in additional iatrogenic shortening of the MT I and might favor postoperative transfermetatarsalgia. Methods: A 3-dimensional model of a foot was obtained from CT scans of a cadaveric foot. The MT I of the 3-dimensional model was then pivoted medially to simulate a severe hallux valgus deformity of an intermetatarsal angle (IMA) of 18° and an intermediate hallux valgus deformity of an IMA of 13°. A ReveL operation was simulated to correct the IMA to 8° for the severe and the intermediate Hallux valgus. Therefore the osteotomy angle in the coronal plane (f=0) was chosen perpendicular to the axis of the second metatarsalia. Afterwards the length of MT I was measured. This procedure was repeated for an posterior altered osteotomy angle (f = 5°,10°, 15° and 20°). Results: The change in MT I length resulting from an osteotomy perpendicular to the axis of MT II was 0.6 mm for a severe hallux valgus (IMA correction from 18° to IMA 8°) and 0.3 mm for a moderate hallux valgus (IMA 13° to IMA 8°). A posterior deviation of the osteotomy angle led to additional shortening (max. 2.9 mm) with a total shortening of up to 3.5 mm (Figure 3). To avoid any shortening of MT I an osteotomy slightly pointing anterior (negative f) of 3.5° (IMA change of 10°) and 3° (IMA change of 5°) was found. Conclusion: ReveL procedure led only to a maximum shortening of 3.5 mm for a posterior deviation of 20°. Considering recently described MT I length cut off values of 2-3 mm for avoiding transfermetatarsalgia the osteotomy should be performed within an anterior directed cut angle of 4° and a posterior directed cut angle of 10° for the correction of a severe hallux valgus. However, further studies are needed to investigate the clinical impact of our findings.

Abstract Background Scarf and Chevron Osteotomy have been widely used for Hallux Valgus Deformity(HVD) to correcting hallux valgus angle (HVA) and intermetatarsal 1-2 angle (IMA), but there still have controversy which approach is the best way to repair HVD,this study aims to use meta-analysis to evaluate the clinical outcomes of Scarf and Chevron Osteotomy for Hallux Valgus Deformity.Methods Pubmed, Embase, Medline and Cochrane library databases were searched for relevant studies published before September 1, 2019. Studies clearly reporting a comparison of Scarf and Chevron Osteotomy for Hallux Valgus Deformity were selected. The Post-operative hallux valgus angle (HVA) and intermetatarsal 1-2 angle (IMA) were evaluated and also the correction of HVA and IMA. The weighted mean differences and relative risks were calculated using a fixed-effects or random-effects model.Results Five studies were included in this meta-analysis,one were prospective randomized controlled trials and three were randomized control trials.A total of 434 patients (210 Scarf and 224 Chevron) were enrolled in the studies.Compare Scarf Osteotomy,Chevron Osteotomy can significantly decreaseed Post-operative hallux valgus angle (HVA)[MD = 1.92 95% CI (1.21 to 2.63),P < 0.0001],but there have no significantly difference between Scarf and Chevron Osteotomy groups in terms of Postoperative intermetatarsal angle (IMA),the correction of IMA and HVA(C-IMA/HVA),DMAA,AOFAS and complication incidence[MD = 0.42, 95% CI (-0.34 to 1.17),P=0.28;MD = -0.30, 95% CI (-0.72 to 0.12),P =0.16; MD = -0.88, 95% CI (-2.34 to 0.57),P =0.23;MD = -0.78, 95% CI (-2.29 to 0.72),P =0.31;MD = -2.01, 95% CI (-9.81 to 5.61),P =0.59 and OR=0.80, 95% CI (0.40 to 1.60),P=0.53 respectively].Conclusion Compare Scarf osteotomy,Chevron Osteotomy can significantly decreaseed Post-operative hallux valgus angle (HVA) and other clinical outcomes are similar between the two treatments.

A modification of the scarf osteotomy bunionectomy is described. The modification involves a change in the movement of the osseous fragments from lateral transposition to lateral rotation of the metatarsal head fragment around a stationary axis at the metatarsal base. Rotation of the distal fragment in this manner allows greater than 50% transposition and, therefore, higher intermetatarsal angle corrections can be obtained as compared to a transpositional scarf osteotomy. The configuration of the scarf osteotomy is more stable to the stress of weightbearing than the closing base wedge osteotomy, and this modification can provide a useful alternative to closing base wedge osteotomy for the correction of severe hallux valgus deformity.

Background: Scarf midshaft metatarsal osteotomy has become increasingly popular as a treatment option for moderate-to-severe hallux valgus deformities because of its great versatility. Numerous studies on Scarf osteotomy have been published. However, no prospective studies were available until 2002. Since then, only short-term follow-up prospective studies have been published. We present the results of a prospective study of 21 patients treated by Scarf osteotomy for hallux valgus with follow-up of 8 years. Methods: Between August 1, 1999, and October 31, 1999, 23 patients (23 feet) with moderate-to-severe hallux valgus deformity were included. Clinical (American Orthopaedic Foot and Ankle Society score) and radiologic (hallux valgus angle, first intermetatarsal angle, and sesamoid position) evaluations were performed preoperatively and 1 and 8 years postoperatively. Results: Clinical evaluation showed a significant improvement in the mean forefoot score from 47 to 83 (of a possible 100) at 1 year (P &lt; .001). Radiographic evaluation showed significant improvement in the hallux valgus angle (mean improvement, 19°; P &lt; .001) and in the intermetatarsal angle (mean improvement, 6°; P &lt; .001). These clinical and radiographic results were maintained at the final evaluation 8 years postoperatively. Conclusions: Scarf osteotomy tends to provide predictable and sustainable correction of moderate-to-severe hallux valgus deformities. (J Am Podiatr Med Assoc 100(1): 35–40, 2010)
