Background Hallux valgus, one of the most common deformities of the great toe, may cause pain, dysfunction, and impaired gait pattern. In this retrospective study we report the results of a new type of distal metatarsal osteotomy combined with distal soft-tissue release in patients with mild-to-moderate hallux valgus deformity. Methods This new technique was used in the management of 32 feet of 31 patients (eight men and 23 women) with mild-to-moderate hallux valgus. Hallux valgus angle, intermetatarsal angle, and distal metatarsal articular angle were measured on preoperative, early postoperative (6–8 weeks), and late (1 year) postoperative radiographs. American Orthopaedic Foot and Ankle Society hallux metatarsophalangeal score was calculated. Sesamoid position, by considering medial sesamoid position, and metatarsal shortness were also measured. Results Statistically significant differences were detected between the preoperative and late postoperative measurements of the hallux valgus angle, distal metatarsal articular angle, intermetatarsal angle, and sesamoid position parameters in patients operated on with this technique. Improvement was 14° for the hallux valgus angle, 4° for the distal metatarsal articular angle, and 4° for the intermetatarsal angle. Sesamoid position was also improved, and the mean American Orthopaedic Foot and Ankle Society score was significantly improved. Metatarsal shortness greater than 2 mm was observed in two patients without resulting in any clinical discomfort. Conclusions This new technique was easy, safe, and promising in patients diagnosed as having mild-to-moderate hallux valgus deformity.

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.

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.

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)

We retrospectively reviewed the results of using a biplanar chevron osteotomy performed on patients who presented with hallux valgus deformities with an increased distal metatarsal articular angle (DMAA). The study included 17 feet (14 patients) of 12 women and 2 men. The average follow-up was 33 months. The average American Orthopaedic Foot and Ankle Society Hallux Metatarsophalangeal-lnterphalangeal Clinical Rating Score was 91. Ten of the 14 patients (13 of 17 feet) stated that they would choose to undergo the procedure again. The hallux valgus angle was improved from an average of 22° to 18°, the intermetatarsal angle from 11° to 9°, and the DMAA from 16° to 9°. We have demonstrated this procedure to be useful in the treatment of symptomatic bunion deformities with an increased DMAA.

Category: Bunion Introduction/Purpose: An arch collapse model has been described for a multitude of foot and ankle problems that is based on a gastrocnemius equinus contracture producing a predictable collapse that has been described in five distinct phases. Previous studies have evaluated the presence of pes planovlagus in hallux valgus patients and concluded that this is a rare occurance. The Grand Rapids arch collapse model reviews adult foot pathology and believes there is a link between bunions and flatfeet. We wanted to evaluate patients with flatfeet and determine if they had an associated bunion deformity. Based upon the arch collapse model, there should be a significant number of flatfeet with an associated bunion deformity and our goal was to see if this proved to be true. Methods: We retrospectively reviewed the radiographs of patients diagnosed with a flatfoot based upon their ICD 9 and 10 codes in the senior author’s practice. For each patient, we used standard anteroposterior and lateral foot radiographs obtained on all new patients. Initially, we had 254 feet but had to exclude 93 feet due to inadequate radiographs, normal radiographs (normal meary’s angle and talonavicular coverage angle) or in patients who already had surgical procedures to the foot. This left 161 feet radiographs for review. We then measured the Meary’s angle on the lateral images and the talonavicular coverage angle, hallux valgus angle, intermetatarsal angle and sesamoid position on the anteroposterior radiographs. Results: Of the 161 feet that remained in the study, only 6 feet (3.7%) had no radiographic evidence of a bunion based upon sesamoid position, hallux valgus angle or the intermetatarsal angle. We did find a correlation with the severity of the flatfoot based upon the Meary’s angle and the talonavicular coverage angle with the severity of the bunion deformity defined by the sesamoid position, hallux valgus angle and the intermetatarsal angle. As the flatfoot got worse, the bunion did so as well. Conclusion: Our findings would seem to fit with the Grand Rapids arch collapse model. The hypermobility of the first ray that creates the bunion deformity then allows the arch to ultimately collapse. It also does not seem to contradict what has been found previously. Earlier studies showed a low association between patients with bunions who also had flatfeet. This would make sense as the deformity may not have progressed to the flatfoot yet. However, in our study the deformity has already progressed to a flatfoot and almost all have some radiographic evidence of a bunion.

Hypermobility of the first metatarsal cuneiform joint has been implicated as a cause of the hallux valgus deformity. The objective definition of hypermobility at this joint, however, has not been clearly defined. We used a modified Coleman block test to accentuate motion at the first metatarsal cuneiform joint in order to measure physiologic limits of motion in vivo. This motion was compared with radiographic analysis of the feet, which included the hallux valgus angle, intermetatarsal angle, and medial cortical thickening at the midshaft of the second metatarsal. This assessment was performed on 100 feet (50 right feet and 50 left feet in 50 patients). The average intermetatarsal angle was 8.7° (range, 4–14°), the average hallux valgus angle was 11° (range, 4° of varus to 30° of valgus), and the average midshaft medial cortical thickness was 3.2 mm (range, 2.0–5.5 mm). Pearson's correlation coefficient was calculated to compare these factors. The relationship between variables was found to be small ( r ≤ 0.2). Motion was noted to occur in the normal foot at this joint and a range of normal values for medial cortical thickness was identified.

The objective of this study was to compare the effects of wearing an insole with toe separator and night splint on hallux valgus and intermetatarsal angles and also on the intensity of pain in patients suffering from painful hallux valgus deformity. Subjects in this study consisted of 30 female patients aged 19 – 45 years (mean 27.83 ± 8.91) who were divided into two groups. The first group received the insole and toe separator and the second group received night splint. Hallux valgus angle and intermetatarsal angle were radiographically measured before and after a 3-month study period. Foot pain intensity was assessed by 10 cm Visual Analogue Scale before and after intervention. After statistical analysis the reduction of pain was significant in the first group ( p < 0.05) whereas in the second group no significant difference was obtained. The hallux valgus angle and intermetatarsal angle decreased in both groups; however, the reduction was not significant. According to the results of this study, using night splint seems to have no effect on painful hallux valgus deformity. On the other hand, although the insole with toe separator significantly decreased the pain intensity in these patients and was a good option for pain reduction, it was not effective in improvement of the great toe angles.

End Of Treatment

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.

The purpose of this study was to determine the intra-observer and inter-observer reliability of physicians on a repetitive basis in making angular measurements of hallux valgus deformities. The hallux valgus angle, the 1–2 intermetatarsal angle, and the distal metatarsal articular angle and the assessment of congruency/subluxation of the first MTP joint were evaluated on a repetitive basis. Physicians were provided with a series of black and white photographs of radiographs with a hallux valgus deformity. Three different sets of photographs randomly ordered were sent at a minimum interval of six weeks to the participants. Participating physicians were extremely reliable in the measurement of the 1–2 metatarsal angle. 96.7% of the photographs were repeatedly measured within a range of 5 degrees or less. The angular measurements to determine the hallux valgus angle were slightly less reliable, but 86.2% of photos were repeatedly measured within a range of 5 degrees or less. In the measurement of the distal metatarsal articular angle, 58.9% of photographs were repeatedly measured within a range of 5 degrees or less. There was a wide range within physician evaluators who recognized very few congruent joints (2 of 21) and those who recognized several congruent joints (11 of 21). Most physicians appeared to be internally consistent in the assessment of MTP congruency; however, some photographs were much more difficult to assess than others. This study validates the reliability of the measurement of the hallux valgus and the 1–2 metatarsal angle. The inter-observer reliability in the measurement of the distal metatarsal articular angle is questioned.
