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.

Category: Bunion Introduction/Purpose: In hallux valgus deformity less weight can be borne by the first ray which may lead to transfer metatarsalgia and lesser toe deformities. Depending on the exact configuration of the bone cuts during the scarf procedure, an iatrogenic shortening of the first metatarsal may occur which may diminish weightbearing ability of the first ray as well, causing transfer metatarsalgia. The aim of the present study was therefore to determine preoperative and postoperative changes in length of the first metatarsal by using different methods of measuring metatarsal length. Methods: A consecutive series of 118 feet in 106 patients (89% female, 11% male) was enrolled, who underwent correctional osteotomy (Scarf-with/without Akin-Osteotomy) from May 2015 to July 2017 at a single institution. Patients, who underwent additional shortening osteotomy of the metatarsals, were excluded. Average age at the time of surgery was 51 years (range, 14 to 83 years). Pre- and postoperative angle measurement of hallux valgus- and intermetatarsal angle was assessed at between six weeks and three months postoperatively on standardized weight-bearing radiographs in dorsoplantar plane. We also identified early complications in hallux valgus surgery. An assessment and comparison of different methods of measuring metatarsal length (length of first metatarsal, ratio first to second metatarsal, Coughlin method) postoperatively was performed to identify the amount of shortening with this technique. Results: Hallux valgus angle was statistically significant reduced by an average of 18.6° (28.3° preoperatively to 9.7° postoperatively, p < 0.001), intermetatarsal angle by 7.7° (12.8° to 5.1°, p < 0.001). Measuring the length of the first metatarsal, in all three methods a statistically significant reduction of the first metatarsal length could be detected. Mean absolute shortening of 1.8 mm was measured (p < 0.001). The ratio of the first metatarsal to the second metatarsal averaged -0.03 (p = 0.02). The mean relative lengthening of the second metatarsal, using the method described by Coughlin, was 0.42 mm (from 4.51 to 4.89 mm, p < 0.001) on average. Of those three methods, the Coughlin method showed the highest correlation. 6 minor complications were observed (5%). Conclusion: In the current study we could demonstrate a significant reduction of hallux valgus angle and intermetatarsal angle with hallux valgus correction using Scarf-/Akin-Osteotomy, with a low complication rate. However, statistically significant shortening of the first metatarsal could be detected as well. Further research is required to improve and establish a hallux valgus correction technique without shortening of the first metatarsal.

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.

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.

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.

Significant Difference

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.

Abstract Objective. To study the correlative between the sesamoid bones under the head of the first metatarsal and the development of hallux valgus determined with radiographs.Methods.The measurements were performed on the X-ray of 300 normal feet and 300 cases of hallux valgus. The following parameters were measured: hallux valgus angle(HVA); the first-second intermetatarsal angle(IMA) between the axes of the first and second metatarsal;the length of the second metatarsal（CD）;the position of tibial sesamoid(TSP ) measured the percent formed between the tibial sesamoid and the centreline of the first metatarsal;the position of fibular sesamoid(FSP) measured tangent value between fibular sesamoid bone and lateral cortex of first metatarsal bone ; the absolute distances (AB) from the centre of the tibial sesamoid to the long axis of the second metatarsal, the absolute distances (EF) from the centre of the fibular sesamoid to the long axis of the second metatarsal and the absolute distance (GH) from the centre of the tibial sesamoid to the centre of the fibular sesamoid. Then calculate the ratio of AB to CD (K1), EF to CD (K2) and GH to CD (K3). Results.HVA moderately positively correlates with TSP and moderately negatively correlates with FSP in subjects with HVA ≥ 20°. HVA and FSP are strongly negatively correlated in the hallux valgus group. Conclusion.The dislocation of sesamoid bone under the first metatarsal head is an important pathological factor leading to valgus. HVA is positively correlated with TSP and negatively correlated with FSP.

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.

Severe Hallux Valgus

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)

Metatarsus Adductus

Category: Bunion Introduction/Purpose: Hallux valgus treatment in the setting of associated metatarsus adductus is less common and not well described. The presence of metatarsus adductus reduces the gap between the first and second metatarsals. Consequently, it complicates the measurement of the first-second intermetatarsal angle and can limit the area available for transposition of the first metatarsal head. If distal metatarsal articular angle (DMAA) is also increased here, it is difficult to correct. We investigated the effects of rotational distal chevron metatarsal osteotomy (DCMO) on hallux valgus associated with metatarsus adductus and increased DMAA. Methods: Twelve patients, (12 female, 15 feet), of average age 59 (SD 23) with symptomatic hallux valgus associated with metatarsus adductus and increased DMAA underwent a rotation DCMO and were reviewed at an average of 12 months postoperatively. Clinically preoperative and postoperative AOFAS hallux MP-IP scale and satisfaction after the surgery were analyzed. Radiologically hallux valgus angle, the 1st intermetatarsal angle, DMAA before and after the operation was analyzed. Results: Distal Chevron osteotomy was done in 15 cases. After DCMO, The distal fragment was translated to laterally as far as possible and rotated to reduce DMAA. Clinically AOFAS scale was increased from 65.3 points preoperatively to 92.2 points postoperatively. Two patients were not satisfied with the results. Radiologically hallux valgus angle was decreased from 21.8° preoperatively to 8.5° postoperatively. The first intermetatarsal angle was decreased from 11.8° preoperatively to 6.7° postoperatively. DMAA was decreased from 15.8° preoperatively to 5.5° postoperatively. Conclusion: The rotational DCMO was an effective procedure for correcting hallux valgus associated with metatarsus adductus and increased DMAA. It allowed good realignment of the first MTP joint without the need for lesser metatarsal surgery to reduce the metatarsus adductus.

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.
