The Impact

Category: Bunion; Midfoot/Forefoot Introduction/Purpose: Early radiographic outcomes of hallux valgus correction focusing on multiplanar deformity have shown promising results. Surgical correction for patients with preexisting metatarsus adductus is considered more challenging and results in higher recurrence rates following hallux valgus surgery. The purpose of this study was to evaluate the impact of preoperative metatarsus adductus on surgical correction following triplanar first tarsometatarsal (TMT) arthrodesis with early weightbearing for hallux valgus. Methods: A retrospective review was performed of 57 patients (62 feet) aged 39.7 +- 18.9 years who underwent triplanar first TMT arthrodesis between 2015 and 2017 at four institutions. After the operation, patients were allowed early full weightbearing in a walking boot. Patients were grouped based on preoperative metatarsus adductus angles for comparison. Preoperative imaging was reviewed and compared to radiographic imaging at 12 months postoperative. Hallux valgus angle (HVA), intermetatarsal angle (IMA), tibial sesamoid position (TSP), lateral round sign, and sesamoid subluxation (axial) were evaluated. For statistical analysis, one-way analysis of variance (ANOVA) and chi-square tests were performed using JMP 11.0.0 (SAS Institute Inc., Cary, NC). Results: Patients with a preoperative metatarsus adductus angle greater than 20 degrees had significantly higher HVA at 12 months (p = 0.0165). There were no differences in IMA or TSP at 12 months based on preoperative metatarsus adductus (p = 0.7687 and p = 0.8703, respectively). Overall recurrence rate for hallux valgus was 3.2% (2/62 patients), and both of these patients had a preoperative metatarsus adductus greater than 20 degrees. There was significantly more sesamoid axial subluxation at 12 months for patients with preoperative metatarsus adductus greater than 20 degrees (p = 0.0092). Overall, the symptomatic non- union rate was 1.7% (1/62 patients). Conclusion: Preoperative metatarsus adductus greater than 20 degrees resulted in higher HVA and recurrence rates at 12 months after triplanar tarsometatarsal arthrodesis. For patients with preexisting metatarsus adductus, additional consideration should be given to ensure the sesamoids are properly reduced under the crista. Future studies should compare the long-term impact of metatarsus adductus on surgical correction, recurrence, and complications after triplanar tarsometatarsal arthrodesis.

Background:Hallux valgus is a multiplanar deformity of the first ray. Traditional correction methods prioritize the transverse plane, a potential factor resulting in high recurrence rates. Triplanar first tarsometatarsal (TMT) arthrodesis uses a multiplanar approach to correct hallux valgus in all 3 anatomical planes at the apex of the deformity. The purpose of this study was to investigate early radiographic outcomes and complications of triplanar first TMT arthrodesis with early weightbearing.Methods:Radiographs and charts were retrospectively reviewed for 57 patients (62 feet) aged 39.7 ± 18.9 years undergoing triplanar first TMT arthrodesis at 4 institutions between 2015 and 2017. Patients were allowed early full weightbearing in a boot walker. Postoperative radiographs were compared with preoperative radiographs for hallux valgus angle (HVA), intermetatarsal angle (IMA), tibial sesamoid position (TSP), and lateral round sign. Any complications were recorded.Results:Radiographic results demonstrated significant improvements in IMA (13.6 ± 2.7 degrees to 6.6 ± 1.9 degrees), HVA (24.2 ± 9.3 degrees to 9.7 ± 5.1 degrees), and TSP (5.0 ± 1.3 to 1.9 ± 0.9) from preoperative to final follow-up ( P < .001). Lateral round sign was present in 2 of 62 feet (3.2%) at final follow-up compared with 52 of 62 feet (83.9%) preoperatively. At final follow-up, recurrence was 3.2% (2/62 feet), and the symptomatic nonunion rate was 1.6% (1/62 feet). Two patients required hardware removal, and 2 patients required additional Akin osteotomy.Conclusion:Early radiographic outcomes of triplanar first TMT arthrodesis with early weightbearing were promising with low recurrence rates and maintenance of correction.Level of Evidence:Level IV, retrospective case series.

In an 11-year retrospective study of 45 patients (60 feet) with juvenile hallux valgus, a multiprocedural approach was used to surgically correct the deformity. A Chevron osteotomy or McBride procedure was used for mild deformities, a distal soft tissue procedure with proximal first metatarsal osteotomy was used for moderate and severe deformities with MTP subluxation, and a double osteotomy (extra-articular correction) was used for moderate and severe deformities with an increased distal metatarsal articular angle (DMAA). The average hallux valgus correction was 17.2° and the average correction of the 1–2 intermetatarsal angle was 5.3°. Good and excellent results were obtained in 92% of cases using a multiprocedural approach. Eighty-eight percent of patients were female and 40% of deformities occurred at age 10 or younger. Early onset was characterized by increased deformity and an increased DMAA. Maternal transmission was noted in 72% of patients. An increased distal metatarsal articular angle was noted in 48% of cases. With subluxation of the first MTP joint, the average DMAA was 7.9°. With a congruent joint, the average DMAA was 15.3°. In patients where hallux valgus occurred at age 10 or younger, the DMAA was increased. First metatarsal length was compared with second metatarsal length. While the incidence of a long first metatarsal was similar to that in the normal population (30%), the DMAA was 15.8° for a long first metatarsal and 6.0° for a short first metatarsal. An increased DMAA may be the defining characteristic of juvenile hallux valgus. The success of surgical correction of a juvenile hallux valgus deformity is intimately associated with the magnitude of the DMAA. Moderate and severe pes planus occurred in 17% of cases, which was no different than the incidence in the normal population. No recurrences occurred in the presence of pes planus. Pes planus was not thought to have an affect on occurrence or recurrence of deformity. Moderate and severe metatarsus adductus was noted in 22% of cases, a rate much higher than that in the normal population. The presence of metatarsus adductus did not affect the preoperative hallux valgus angle or the average surgical correction of the hallux valgus angle. Constricting footwear was noted by only 24% of patients as playing a role in the development of juvenile hallux valgus. There were six recurrences of the deformities and eight complications (six cases of postoperative hallux varus, one case of wire breakage, and one case of undercorrection).

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.

Background Properly fitted shoes can support the development of growing feet and prevent problems and pathologies, not only in childhood, but also in adulthood. This points to the need to conduct research on the impact of shoe fitting on the structure of the foot in order to raise awareness and importance of this problem, to enable proper decisions regarding the purchase and use of shoes. The aim of this study was to analyze indoor footwear fit and its impact on foot structure in 7-year-old schoolchildren. Methods The CQ-ST podoscope and the Clevermess device were used for measurements. The analysis was carried out using the Mann Whitney U test, Wilcoxon signed-rank test, Chi-square test, regression analysis. Results About 40% of girls and boys had shoes that were incorrectly fitted in length, while as many as 74% of girls and 66% of boys wore shoes that were incorrectly fitted in width. Regression analysis demonstrated a statistically significant influence of the footwear length on longitudinal arch of the right and left foot and the transverse arch of the right foot. In boys, the length of the shoes shows associations with the right and left hallux valgus angle. Conclusion A significant percentage of the studied 7-year-olds, regardless of gender, wears inappropriately fitted shoes. In both sexes, the length of the footwear influenced the longitudinal arch of the right and left foot and the transverse arch of the right foot. Due to the deformity of the first metatarsophalangeal joint, the boys with hallux valgus require footwear which is wider and therefore their shoes need to be bigger in size.

Category: Midfoot/Forefoot Introduction/Purpose: Hallux valgus (HV) is one of the most common forefoot problems. HV is defined as a hallux valgus angle of more than twenty degrees. HV can lead to alterations of the plantar pressure pattern and clinical gait. This study examined the relationship between gait alterations and HV deformities. Methods: We examined 500 residents (161 men and 339 women; >50 years of age) of Miyagawa village in Mie, Japan in 2009, 2011 and 2013. They performed a 6-meter walk test at normal and maximum speed. We examined gait speed, the number of steps, and footprint between patients with normal (HV angle <20; n=350) and HV (HV angle >20; n=150), and between normal-to-mild (HV angle <30; n=436) and moderate-to-severe (HV angle >30; n=64). Their plantar pressure patterns were measured using a gait analyzer (Walk Way MW 1000; Anima, Tokyo, Japan, Figure.1). Statistical analyses were performed using the chi-square test according to sex and use of the hallux ball; the t-test according to age, height, and weight; and logistic regression analysis adjusted for age, sex, and height according to gait speed and the number of steps. P value less than 0.05 was considered significant. Results: With regard to the plantar pressure pattern, the percentage of subjects in the HV group who left a footprint of the hallux ball was significantly lower than that in the normal group. The percentage of subjects in the moderate-to-severe group who left a footprint of the hallux ball was even lower. Analysis of the footprint revealed that the HV group used the hallux ball significantly less during toe-off than the normal group. At both normal and maximum speed, the number of steps and gait speed did not differ significantly between the normal and HV groups. However, when we compared normal-to-mild and moderate-to-severe groups, the number of steps in the moderate-to-severe group was significantly greater than in the normal-to-mild group at maximum walking speed. Conclusion: Analysis of the footprint revealed that the percentage of subjects in the HV group who was able to use the hallux ball during toe-off was significantly less than that in the normal group. The percentage of subjects in the moderate-to-severe group who could use the hallux ball in toe-off was even lower. HV can cause footprint alterations. Moderate-to-severe HV can cause not only footprint alterations but also gait alterations, especially when walking at maximum speed.

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.

Introduction: The purpose of the present study is to evaluate the clinical and radiographic results of simultaneous surgical correction for bilateral hallux valgus compared with unilateral correction using percutaneous forefoot surgery techniques (PFS). Material and Methods: A prospective cohort study of 82 patients (106 feet). The mean follow-up was 58.7[Formula: see text][Formula: see text][Formula: see text]1.5 months (range 22.3 to 112.1). Patients were divided into two groups, unilateral surgical group (group U, 58 feet) and simultaneous bilateral surgical group (group B, 48 feet). Results: Preoperative mean visual analog scale (VAS) was 6.2 points in group U and 6.3 in group B ([Formula: see text]), at the last follow-up it decreased in both groups (1.6 group U and 1.8 group B, [Formula: see text]). AOFAS score improved from approximately 50 points preoperative in both groups, to 88 at the last follow-up. Mean hallux valgus angles in groups U and B changed from 34.7[Formula: see text] and 34.3[Formula: see text] preoperatively ([Formula: see text]), to 21.3[Formula: see text] and 22.4[Formula: see text] follow-up, respectively ([Formula: see text]). With the numbers available, no significant inter-group differences were observed in clinical and radiographic outcomes. Conclusions: PFS is a valid procedure for outpatient simultaneous surgical correction in patients with bilateral hallux valgus. Level of Evidence: II Prospective Comparative Cohort Study.

Background: Bipartite hallucal sesamoids are often found in patients with hallux valgus. However, it is unknown whether bipartite hallucal sesamoids affect the results of hallux valgus surgery or not. The purpose of the present study was to evaluate the outcomes of chevron osteotomy for hallux valgus with and without bipartite hallucal sesamoid. Methods: A total of 152 patients (168 feet) treated with distal or proximal chevron osteotomy for hallux valgus constituted the study cohort. The 168 feet were divided into 2 groups: bipartite hallucal sesamoid (31 feet) and without bipartite hallucal sesamoid (137 feet). Hallux valgus angle (HVA), intermetatarsal angle (IMA), distal metatarsal articular angle (DMAA), tibial sesamoid position, and first metatarsal length were measured for radiographic outcomes and the American Orthopaedic Foot & Ankle Society (AOFAS) hallux metatarsophalangeal-interphalangeal (MTP-IP) score was measured for clinical outcomes. Results: All radiographic measurements and the AOFAS score showed significant ( P < .05) improvement at the time of final follow-up compared with preoperative measurements in both groups. No significant differences ( P > .05) were found between the 2 groups in terms of HVA, IMA, DMAA, tibial sesamoid position, metatarsal shortening, and AOFAS score on final follow-up. Conclusions: This study suggests that bipartite hallucal sesamoids do not affect the results of hallux valgus surgery. Level of Evidence: Level III, retrospective comparative study.

Background: Hallux valgus is a common cause of pain and dysfunction of the foot, sometimes requiring surgical correction when conservative measures fail. Although there are many methods of correction, one of the newer techniques is minimally invasive chevron-Akin (MICA). The aim of the current study is to evaluate clinical and radiographic effectiveness of MICA and narcotic use in a large patient cohort. Methods: All patients in this retrospective study were treated by a single fellowship-trained foot and ankle orthopedic surgeon. Patient demographics were collected for all cases. Preoperative and postoperative intermetatarsal angle (IMA) and hallux valgus angle (HVA) were measured in all patients on weightbearing 3-views radiographs. The Foot Function Index (FFI) was obtained pre- and postoperatively at each visit. All patients were prescribed regular use of ibuprofen for 3 days with acetaminophen and oxycodone reserved for breakthrough pain. Use of narcotic pain medication was recorded. Results: A total of 274 feet in 248 patients were included in the study. Overall, 87.9% were female and 12.1% were male. The mean preoperative IMA and HVA were 13.4 and 29.1 degrees, respectively. The postoperative IMA and HVA were 4.9 and 8.9 degrees, respectively. The mean FFI score part A was 92 preoperatively and 43 postoperatively. Patient satisfaction was 91.6%. The mean postoperative 5 mg oxycodone pill consumption was 2.2. Conclusion: MICA is good method to correct hallux valgus deformity with low postoperative narcotic use. Level of Evidence: Level III, this is a restrospective cohort study of a single surgeon practice.
