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: Bunion Introduction/Purpose: It is still unclear whether generalized ligamentous laxity is a risk factor for recurred hallux valgus deformity. This study was performed to evaluate the intermediate-term clinical outcomes after proximal chevron osteotomy for hallux valgus in patients with generalized ligamentous laxity, and to determine the effect on postoperative recurrence of deformity. Methods: A total of 198 feet from 169 female patients were treated with a proximal chevron osteotomy for hallux valgus with a mean follow-up of 46.3 months. When generalized ligamentous laxity was defined as Beighton score ≥ 5 points, there were 18 patients (10.7%) in laxity group and 151 patients (89.3%) in non-laxity group. Clinical evaluation consisted of the American Orthopaedic Foot and Ankle Society (AOFAS) scores, Foot and Ankle Ability Measure (FAAM), and radiographic measurement of hallux alignment. Risk factors associated with postoperative recurrence were evaluated using univariate analysis. Results: Recurrence rates were 21.7% in the laxity group and 17.1% in non-laxity group (p = 0.218), when defined as hallux valgus angle ≥ 20°. No significant differences of measurement at final follow-up were found between the 2 groups in terms of AOFAS score, FAAM, recurrence rate, hallux valgus angle (HVA), intermetatarsal angle (IMA) and distal metatarsal articular angle (DMAA). Preoperative HVA and IMA were found to be predictive factors of recurrence (OR = 6.3, 4.2; P = .001, .018, respectively). Conclusion: There were no statistical differences in the clinical and radiographic outcomes between hallux valgus with and without generalized ligamentous laxity. Generalized ligamentous laxity demonstrated no definitive effects on postoperative recurrence of hallux valgus deformity.

Category: Bunion, Midfoot/Forefoot Introduction/Purpose: Numerous corrective osteotomies have been performed for surgical treatment of hallux valgus(HV). One of these procedures is distal chevron osteotomy, traditionally indicated for correction of mild to moderate HV. We proposed a new modification of the chevron osteotomy, extended distal chevron osteotomy, to provide even greater stability by extend the contact surface, as well as more effective and accurate correction of the angulation and rotational profile than conventional osteotomy. Methods: Between July 2013 and June 2014, the extended distal chevron osteotomy (DCO) was performed for the treatment of mild-to-moderate hallux valgus deformity in 63 feet (Group A) by the same surgeon. For the extended chevron, the first osteotomy was performed to cut 5-10 mm from the head of metatarsal to the proximal upper 1/3 of the neck. The second osteotomy was performed to cut 2.5~3.0 cm from the upper 1/3 of the neck toward horizontal plane of the plantar surface with an angle of 45~50 degree. Standard foot radiographic measurements, hallux valgus angle(HVA) and intermetatarsal angle(IMA), were recorded to compare with the values of 37 patients (Group B) who were treated by the traditional DCO technique. Results: Mean patient age was 45.3 (range 15–78) years, and 54 patients were available for follow-up at both one and two years postoperatively. Mean follow-up duration was 13.7 (range 4–26) months. In group A, mean HVA decreased from 32.3° preoperatively to 8.4° at final follow-up, while the angle of group B decreased from 32.4° to 11.4°. Mean IMA decreased from 15.1° preoperatively to 7.3° at final follow-up in group A, while the IMA decreased from 15.1° to 8.9° in group B. That way we could verify that the extended chevron osteotomy is more effective for stability and correcting of the angulation and rotational profile than traditional DCO. Conclusion: The extended chevron osteotomy achieved even greater stability and accurate correction of the deformity. Furthermore, it was more effective than traditional chevron osteotomy in terms of correction of the angulation and rotational profile.

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 < .001). Radiographic evaluation showed significant improvement in the hallux valgus angle (mean improvement, 19°; P < .001) and in the intermetatarsal angle (mean improvement, 6°; P < .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)

Bone Structures

Hallux valgus is characterized by the appearance and growth of a painful “lump” in the region of the first metatarsophalangeal joint, the development of forefoot corns, and inability to choose the right shoes, which leads to a significant decrease in the quality of life of these patients. Corrective osteotomies that preserve the metatarsophalangeal joint, for example Austin (Chevron) osteotomy, are usually used for hallux valgus deformity of the I, II degrees. Radiography with the study of the hallux valgus angle (HVA), the intermetatarsal angle (IMA), the distal metatarsal articular angle (DMAA) is a research method that shows the true correlation between bone structures. The correlation between the radiological and functional indicators of osteotomy allows us to determine possible recommendations for indications for surgical treatment of Hallux valgus. Correlation shows that the largest correction of hallux valgus in older patients occurs due to a small adjustment of the angle of DMMA and HVA. IMA had the best correction after Austin osteotomy among patients of a younger age, then the HVA, and the DMMA had minimum correction according to the AOFAS rating scale (Kitaoka). The revealed correlations allow us to determine the correct tactics for the treatment of hallux valgus by identifying the benefits of Austin osteotomy.

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.

The chevron osteotomy for hallux valgus was modified by addition of screw fixation and change of the osteotomy angle. Thirty-six patients underwent this modified osteotomy. All had mild to moderate symptomatic hallux valgus deformities. No other forefoot procedures were performed. Standing radiographs were taken before surgery, at 1 month after surgery, and, for the 15 patients who returned for long-term follow-up, at 1 year or more after surgery. Overall, 35/42 procedures were rated as satisfactory without reservations and 7 were rated as satisfactory with mild reservations. All patients stated that they had some improvement in their preoperative symptoms, which included pain, cosmetic concerns, and shoe wear difficulties. Radiographically, none of the capital fragments displaced and there were no malunions, nonunions, nor evidence of avascular necrosis. The average metatarsophalangeal-1 angle improved 8° and the average intermetatarsal 1–2 angle improved 4°. This modification is relatively simple, increases stability, and allows early weightbearing. In our experience, the modified chevron osteotomy has been a very reliable procedure for mild to moderate symptomatic hallux valgus deformity.

ABSTRACT Aim The scarf osteotomy, as popularized by Barouk, is a versatile osteotomy for the correction of moderate and severe hallux valgus deformity. However, this technique requires extensive exposure, fixation, and increased operative time, and is technically demanding. We describe and present our results of a short scarf osteotomy (SSO), which retains all the cuts of a standard scarf but requires a reduced exposure, less metalwork, less operating time, and is more economical. Materials and methods All patients who underwent SSO between January 2010 and December 2012 with minimum follow-up of 12 months were eligible for the study. Preoperative, intraoperative, and postoperative radiographs were available for radiological assessment. Results In this study, 84 patients and 94 feet were included; 90% of patients were satisfied overall, with 83% of patients recommending this surgery to a friend. The hallux valgus angle improved from a preoperative mean of 30.89° (17.4—46.8) to 12° (4—30) postoperatively (p = 0.0001). The intermetatarsal angle improved from a preoperative mean of 15.05° (10.3—21.1) to 7.14° (4—15.1) postoperatively (p = 0.0001). The average sesamoid coverage improved from grade 2.18 (1—3) preoperatively to 0.57 (0—2) postoperatively (p = 0.0001). The average American Orthopedic Foot and Ankle Score improved from 51.26 (32—88) preoperatively to 91.1 (72—100) postoperatively (p = 0.0001). Conclusion We believe that this osteotomy is a novel procedure producing good to excellent results in most cases of hallux valgus. Biologically, the decreased exposure should improve healing and reduce the risk of avascular necrosis. We strongly recommend this osteotomy for most cases of hallux valgus surgery.

From 1986 to 1990, 42 feet in 30 patients had a combined chevron osteotomy and lateral release to correct their painful bunion deformity. Seventeen patients, 23 feet, were available for follow-up. The purpose of this study was to evaluate the outcome of this procedure and to determine the incidence of avascular necrosis. The patients were examined by an independent examiner, radiographs obtained, and questionnaires filled out. Avascular necrosis was determined using plain films read by a musculoskeletal radiologist who did not know the outcomes. The average age was 45 years at the time of the procedure. Average follow-up was 50 months. The preoperative intermetatarsal angle averaged 13° and the hallux valgus angle averaged 31°. At study follow-up, the intermetatarsal angle averaged 8° and the hallux valgus angle averaged 17.5°. The results were graded by the Mayo Clinic Forefoot Scoring System (75-point scale) and a subjective scoring system. Average postoperative Mayo Clinic score was 67. Fifteen feet were subjectively rated as excellent, six as good, and two as fair. Complications occurred in four feet. Hallux varus occurred in two feet, extension contracture in one foot, and an infection in one foot. None of the feet developed definite radiographic evidence of avascular necrosis. Distal chevron osteotomy combined with a lateral release for corrective bunion surgery has come under scrutiny, because of the risk of avascular necrosis of the first metatarsal head. However, our study showed no evidence of avascular necrosis on radiographs. In addition, 91% of patients had good to excellent results at an average 50-month follow-up.
