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.

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.

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.

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.

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.

Objective: To analyze the outcomes of percutaneous hallux valgus correction using the Reverdin-Isham osteotomy through clinical and radiographic studies. Methods: We retrospectively evaluated 43 feet in 38 patients with mild or moderate hallux valgus from June 2009 to July 2018. The mean age at surgery was 59 years; the mean postoperative follow-up time was 79 months. All patients treated with the Reverdin technique modified by Isham were evaluated in the pre- and postoperative periods using the American Association Orthopedic Foot and Ankle Society (AOFAS) score; we radiographically measured the hallux valgus angle (HVA), the intermetatarsal angle (IMA) and the first distal metatarsal articular angle (DMAA). Results: The AOFAS score increased by an average of 55 points. On average, the HVA decreased by 14°, the IMA by 3° and the DMAA by 9°. The mean reduction in the length of the first metatarsal bone was 0.3 cm. Conclusion: This surgical technique was effective for hallux valgus correction, demonstrating good angle correction and a marked increase in the AOFAS score.

A modified Lapidus procedure was introduced at Harborview Medical Center in 1979 for the treatment of symptomatic hallux valgus with hypermobile first ray. The results of the procedures were reviewed retrospectively in 32 patients with 40 feet that were operated on between 1979 and 1984. Preoperative diagnosis was symptomatic hallux valgus complex with hypermobile first ray in 33 and failed bunion surgery in 7. Follow-up ranged from 30 months to 6 1/2 years. Union of the arthrodesis site occurred in 36 (90%). The average preoperative intrametatarsal angle was 14° (range 7.5 to 20°) and the hallux valgus angle was 26° (range 0 to 50°). At healing, the angles were as follows: intermetatarsal angle 6° (range 0 to 18°) and hallux valgus angle 11° (range −3 to 30°). The average change in the length of the first metatarsal was −5 mm for those without bone graft and +4 mm for those with bone graft. Of 33 feet operated on as a primary procedure, successful results were reported in 75% by our rating system. Of 7 feet operated on for failed previous surgery, all were improved. Best results were obtained in those with multiple screw fixation, use of bone graft, and attention to plantarflexion of the first metatarsal.

Sixty-seven closing wedge arthrodesis procedures of the first metatarsocuneiform joint were performed in 41 females and 12 males. Follow-up averaged 28 months (range 16–49 months) and was performed in 51 of 53 patients with a questionnaire, clinical examination, and comparison of pre- and postoperative weightbearing radiographs. The average hallux valgus angle was 34.5° (range 20°–75°) and was corrected to 13.0° (range −10°–22°) postoperatively. The average intermetatarsal angle was 14.3° (range 9.5°–34°) and was corrected to an average of 5.8° (range 0°–12°) postoperatively. Complications included seven superficial pin tract infections, three symptomatic dorsal bunions, one of which required repeat surgery, seven nonunions, one of which was symptomatic, one hallux varus, and three neuromas of the deep peroneal nerve. The range of motion of the hallux metatarsophalangeal joint was 85% of normal postoperatively. A total of 77% of the patients were totally relieved, 15% partially relieved, and 8% not relieved with respect to pain, comfort, appearance of the foot, and shoewear following surgery. The specific indications for performing this operation are discussed.
