Category: Bunion Introduction/Purpose: Hallux valgus (HV) is one of the most common deformities of the foot resulting in pain and lifestyle modification of the patient. Recurrence rates of 10-47% have been documented in single individual osteotomy series. Unfortunately, surgical correction and recurrence are often defined as changes related to normal radiographs and not actually as the magnitude of correction lost with follow-up. Currently there have not been studies evaluating the percentage of recurrence of intermetatarsal angle (IMA) and hallux valgus angle (HVA). As there is substantial difference in starting IMA and HVA, as well as amount of surgical correction, our goal was to evaluate the percentage loss of correction over time comparing preoperative, initial postoperative and minimum of 2-year follow up radiographs among three different surgical correction techniques. Methods: This is a retrospective chart review study that examines the weight-bearing radiographic measurements of patients undergoing hallux valgus corrective surgery at a single institution over 5 years. Fifty-three patients were divided into first tarsometatarsal arthrodesis (i.e. Lapidus), mid-diaphyseal osteotomies (i.e. scarf), and distal metatarsal osteotomies (i.e. chevron). The preoperative, initial postoperative, and final follow up weight-bearing radiographs were measured for intermetatarsal angle (IMA) and hallux valgus angle (HVA). Primary outcome was percentage of recurrence of IMA and HVA, with the difference in angles between preoperative and initial postoperative weight-bearing films being considered 100% correction. The percentage of recurrence between initial postoperative and most recent follow up was then calculated (Figure 1A). A one-way analysis of variance (ANOVA) test and post-hoc Tukey-Kramer tests were used to compare preoperative IMA and HVA and percentage recurrence of IMA and HVA at most recent follow up. Results: There was no significant difference between Lapidus (14.3deg) and mid-diaphyseal osteotomies (12.7deg) in preoperative IMA (p-value=0.26). There was a significant difference between Lapidus (-0.3deg) and mid-diaphyseal (2.8deg) osteotomies for degree of hallux valgus recurrence as measured by IMA between initial postoperative films and final 2-year follow up (p-value=0.009). Lapidus procedure showed a greater magnitude decrease in IMA degrees from preoperation to final follow up compared to distal osteotomy (p-value=0.037) and trended toward significance compared to mid-diaphyseal (p-value=0.056). Mid-diaphyseal osteotomies (30%) showed a statistically significant higher percentage of IMA recurrence compared to Lapidus (-11%) (p-value=0.0014) (Figure 1B). When comparing percentage recurrence of HVA, distal osteotomies had a significantly smaller rate of recurrence when compared to the diaphyseal osteotomies (p-value=0.030). Conclusion: Though Lapidus and mid-diaphyseal osteotomies were performed for patients with a similar preoperative IMA, mid-diaphyseal osteotomies had a significantly higher percentage of recurrence at 2-year follow up compared to Lapidus procedures. Moreover, Lapidus procedures trended toward greater overall of IMA correction compared to mid-diaphyseal osteotomies. When either a Lapidus or mid-diaphyseal osteotomy is indicated, a Lapidus procedure may result in decreased rate of radiographic recurrence of hallux valgus at 2 years.

The Austin osteotomy is a widely accepted method for correction of mild and moderate hallux valgus. In view of publications by Kitaoka et al. in 1991 and by Mann and colleagues, a more radical lateral soft tissue procedure was added to the originally described procedure. From September 1992 to January 1994, 85 patients underwent an Austin osteotomy combined with a lateral soft tissue procedure to correct their hallux valgus deformities. Seventy-nine patients (94 feet) were available for follow-up. The average patient age at the time of the operation was 47.1 years, and the average follow-up was 16.2 months. The average preoperative intermetatarsal angle was 13.9°, and the average hallux valgus angle was 29.7°. After surgery, the feet were corrected to an average intermetatarsal angle of 5.8° and an average hallux valgus angle of 11.9°. Sesamoid position was corrected from 2.1 before surgery to 0.5 after surgery. The results were also graded according to the Hallux Metatarsophalangeal Interphalangeal Score, and the functional and cosmetic outcomes were graded by the patient. Dissection of the plantar transverse ligament and release of the lateral capsule repositioned the tibial sesamoid and restored the biomechanics around the first metatarsophalangeal joint. There was no increased incidence of avascular necrosis of the first metatarsal head compared with the original technique.

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.

We evaluated the results of 33 feet in 23 patients who underwent a basilar crescentic osteotomy with a modified McBride procedure with a minimum 24-month follow-up. The average hallux valgus improved from 37.5° to 13.8° and the intermetatarsal 1–2 angle from 14.9° to 4.7°. The angle of declination of the first metatarsal was found to have dorsiflexed an average of 6.2°. Unfortunately, osteotomies secured with staples dorsiflexed to a greater degree. Bilateral foot surgery produced results similar to those with unilateral procedures. Four of our patients developed a hallux varus (range 2–8°); however, none were dissatisfied at the time of evaluation. Although this bunion procedure resulted in more prolonged swelling and pain than a distal osteotomy, it should be considered for more complex deformities to avoid the failure that a distal metatarsal osteotomy might produce given a high 1–2 intermetatarsal angle or a high hallux valgus angle.

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)

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.

Foot Alignment

Background: The relationship between juvenile hallux valgus (JHV) and flatfoot has not been clearly established. The aim of this study was to assess radiographic measurements in feet with JHV compared with matched controls and to investigate whether the foot alignment of JHV is related to flatfoot. Methods: We retrospectively reviewed 163 patients with JHV as defined as hallux valgus angle greater than 20 degrees and intermetatarsal greater than angle than 10 degrees. Patients with open physes of the feet and who had weight-bearing radiographs of the feet were included. Another 55 normal participants served as controls. Patients with JHV were divided into 2 subgroups: Group 1 included patients with asymptomatic JHV and group 2 consisted of those treated with correctional surgery for painful JHV. Twelve radiographic indices were analyzed, including calcaneal pitch angle, tibiocalcaneal angle, talocalcaneal angle, naviculocuboid overlap, talonavicular coverage angle, lateral talo–first metatarsal angle, anteroposterior talo–first metatarsal angle, metatarsus adductus angle, hallux valgus angle, intermetatarsal angle, distal metatarsal articular angle, and first metatarsal cuneiform angle. The groups were compared by age, gender, and the above radiographic parameters. Results: There was no significant difference in hindfoot alignment of patients with JHV and controls. Naviculocuboid overlap ( P <.001), lateral talo–first metatarsal angle ( P = .002), and metatarsus adductus angle ( P = .004) were significantly greater in patients with JHV than in controls, whereas the anteroposterior talo–first metatarsal angle ( P = .026) was significantly less. Symptomatic and asymptomatic JHV patient subsets showed no significant radiologic differences. Conclusion: Radiographic profiles in patients with JHV were inconsistent with regard to features of flatfoot, and foot alignment was unrelated to the presence of symptoms or degree of deformity in JHV.

Objective: Hallux valgus is a progressive triplanar deformity of the forefoot with an important rotational component (RC) in the first metatarsal, which has been associated with recurrence. There is controversy about using weight-bearing vs. non-weight-bearing radiographs in RC measurement. This study aims to assess interobserver reliability for RC of the first metatarsal using a non-weight-bearing sesamoid view, as well as to correlate the hallux valgus angle, intermetatarsal angle, distal metatarsal articular angle (DMAA) and sesamoid position regarding RC. Methods: An observational, cross-sectional and descriptive study was conducted with 81 feet from 48 patients (66.6% female). RC was evaluated regarding the first metatarsal proximal shaft in non-weight-bearing axial metatarsal radiographs and weight-bearing anteroposterior radiographs. Measurements were taken independently by two foot and ankle subspecialists and an orthopedic resident, all of whom were blinded. Results: Statistically significant intraclass correlations (p = 0.02) were obtained for first metatarsal RC assessment among the three observers (95%CI 0.01–0.65; Cronbach’s α =0.41) in non-weight-bearing axial metatarsal views. Significant correlations (Spearman ρ) were also found for hallux valgus angle (p = 0.04) and DMAA (p = 0.01), and non-significant correlations were found for intermetatarsal angle and sesamoid position (p > 0.05). Conclusion: The significant correlations between hallux valgus angle and DMAA for RC suggest that RC is isolated from the first metatarsal bone structure. This practical assessment method may isolate the first metatarsal head RC regarding the proximal metatarsal in the metaphyseal region and could be useful in centers where weight-bearing CT scans are not available.

Background: Hypermobility of the first ray has been evaluated using various methods and has conventionally been considered to be involved in the pathology of hallux valgus. We hypothesized that hypermobility of the first ray in hallux valgus could be decreased by simply correcting foot alignment without arthrodesis. This study sought to evaluate first-ray mobility using weightbearing computed tomography (CT) before and after proximal oblique osteotomy and also in healthy volunteer’s feet. Methods: Subjects were 11 feet of 11 patients with primary hallux valgus who underwent surgery with a plantarly applied anatomic precontoured locking plate and 22 feet of 11 matched healthy volunteers. We performed nonweightbearing and weightbearing (using a load equivalent to body weight) CT scans using an original loading device preoperatively and 1-1.5 years postoperatively. Three-dimensional displacement of the distal bone relative to the proximal bone was quantified for each joint of the first ray by comparing nonweightbearing and weightbearing CT images. Results: At baseline, there were significant differences in hallux valgus angle ( P < .001) and 1-2 intermetatarsal angle ( P < .001) between healthy volunteer’s feet and preoperative hallux valgus feet. Hallux valgus angle ( P < .001) and 1-2 intermetatarsal angle ( P < .001) differed significantly between before and after surgery. All first ray joint displacement under loading decreased postoperatively to within 2° of that in healthy volunteer’s feet and showed no significant difference between postoperatively hallux valgus feet and healthy volunteer’s feet ( P > .05). Conclusions: We found that first metatarsal osteotomy even without arthrodesis corrected deformity and decreased mobility of the first ray after hallux valgus surgery. Level of Evidence: Level III, case-control study.

Background: We compared the radiographic and clinical outcomes of moderate and severe hallux valgus treated by extended distal chevron osteotomy (EDCO) and distal soft tissue release (DSTR). Methods: We performed a retrospective analysis comparing the utility of EDCO for the treatment of moderate (36 patients, 46 feet) and severe (36 patients, 42 feet) hallux valgus. The radiologic outcomes were evaluated based on the preoperative and 3-year follow-up x-rays. The clinical results were investigated based on the 3-year follow-up Manchester-Oxford Foot Questionnaire (MOXFQ), patient satisfaction, and postoperative complications. Results: The mean postoperative intermetatarsal angle, hallux valgus angle, tibial sesamoid position, and relative metatarsal bone length were significantly different compared with the preoperative values for both the moderate and severe groups ( P < .001). At 3-year follow-up, intergroup differences were observed in the mean postoperative intermetatarsal angle ( P = .001), hallux valgus angle ( P = .003), and tibial sesamoid position ( P = .013); however, mean radiographic results were within the normal range for both groups. There were no intergroup differences for either the first metatarsal bone length ( P = .172) or shortening ( P = .621). No significant difference in MOXFQ ( P = .525) was evident between the groups at 3-year follow-up. In satisfaction analysis, 82.6% of the moderate group reported good to excellent results, as did 81.0% of the severe group ( P = .815). A total of 7 complications were reported in each group ( P = 1.000). Conclusion: The present study showed that midterm mean radiographic results of both moderate and severe hallux valgus treated by EDCO with DSTR were favorable, and those values were within the normal range. Clinical outcomes were comparable between the 2 groups, including overall efficacy. Based on these results, we recommend EDCO with DSTR as an efficient and reliable operative option for both moderate and severe hallux valgus. Level of Evidence: Level III, retrospective comparative study.

Category: Bunion Introduction/Purpose: Hallux Valgus (HV) is a multiplanar deformity with metatarsal varus and pronation. Pronation is a frequently undiagnosed and/or untreated deformity parameter being a recognized postoperative relapse factor. The objective of this research is to estimate the pronation prevalence in HV and evaluate the pronation correction after conventional Hallux Valgus surgery. Methods: 105 patients with operated Hallux Valgus were followed between 2010 and 2016. Mean age and follow up (months) was 53 and 23 respectively. For all patients, pre and postoperative angular measurements (Pronation angle, hallux valgus angle, HVA, and intermetatarsal angle, IMA) and the operative technique used was recorded. For pronation measurements, a 4-stage classification was used by means of 4 metatarsal templates with different degrees of pronation (0, 10, 20, 30 degrees). Surgical techniques used were Chevron, Scarf and Poscow. Results: Regarding pronation angle, 95 out of 105 patients (90%) had some degree of metatarsal pronation (10% had no pronation). The most common pronation value was 20 degrees (60%). No change in metatarsal pronation angle was observed at final follow up with any technique used. Regarding HVA and IMA pre/postoperatively: HVA: 29/11, IMA: 14/8. Chevron, Scarf and Poscow were used in 15, 67 and 23 patients respectively. 66% of cases decreased sesamoid position in one or more stages. Conclusion: Metatarsal pronation is a frequent finding in Hallux Valgus patients (90%). The most common pronation deformity is 20 degrees. It was not corrected with any technique used (Chevron, Scarf, Poscow). This fact is explained probably because these osteotomies are purely translational aiming to correct the metatarsal varus and not the metatarsal pronation.
