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: 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: Hallux valgus recurrence is an unsatisfactory complication, with many causes postulated. This study investigated the effect of pes planus on recurrence after scarf osteotomy. Methods: A total of 183 feet were retrospectively reviewed. All patients were treated with a scarf osteotomy and if required Akin osteotomy. We measured preoperative lateral talus first metatarsal angle (T1MA) to study pes planus; an angle of under −4 degrees was considered pes planus. We measured pre and postoperative hallux valgus angle (HVA), intermetatarsal angle (IMA), and sesamoid location. In total 164 feet were suitable for inclusion, with follow-up of at least 6 months (10 males and 154 females, mean age: 52 years). Results: Recurrence frequency (HVA greater than 15 degrees) was 27 feet (16%). Hallux valgus recurrence was not influenced by gender ( P value = .66) or preoperative IMA ( P value = .48). Preoperative HVA greater than 35 degrees was associated with increased frequency of recurrence ( P value = .004). Those with T1MA less than −10 degrees demonstrated progression in HVA and deterioration in sesamoid location up to 6 months postoperatively ( P value = .038). HVA did not progress beyond 6 months. The prevalence of recurrent hallux valgus with normal T1MA was 1%, in T1MA −4 to −10 degrees it was 29% and in T1MA less than −10 degrees it was 47% ( P value <.001). Breaks in T1MA less than −4 degrees were found at the naviculocuneiform joint in 68% of feet in this series. Conclusion: The prevalence of hallux valgus recurrence correlated with the severity of pes planus. Level of Evidence: Level III, retrospective cohort study.

Angular Measurements

There is some uncertainty as to whether the distal metatarsal articular angle (DMAA) is a real entity or just radiographic artifact and whether it can be reliably measured. If it is intrinsic to the bone, it should not change with bone position. If it is clinically useful, it should be reproducible. Pre-operative and post-operative radiographs of 32 patients undergoing a proximal bony procedure of the first ray were evaluated independently by three foot and ankle specialists in order to determine the intra and inter-observer reliability of the distal metatarsal articular angle (DMAA). In addition, the hallux valgus angle (HVA), intermetatarsal angle (IMA) and joint congruency/subluxation were determined. We used ANOVA (Scheffe's F-test) to determine reliability of the angular measurements; a p value of less than 0.05 indicates poor reliability and a p value of greater than 0.05 indicates reliability. Intra-observer reliability was good for all angular measurements (HVA, IMA, DMAA pre-op, and DMAA postop) with p values ranging from 0.33 to 0.95. Inter-observer reliability of the HVA and IMA was good (p = 0.63 and p = 0.32). Inter-observer reliability of the pre-op DMAA approached statistically poor reliability (p = 0.09) and the post-op DMAA reliability was poor (p = 0.002). The DMAA reduced after the proximal procedure as measured by all observers, and averaged a reduction of 3.9°. Weighted kappa analysis also revealed that there was poor agreement in the determination of congruency and subluxation (Kappa statistic ranged from 0.07 to 0.19). This study suggests that there may be limited value in the DMAA as a clinical measure as it varies with examiner and with the hallux valgus angle.

The purpose of this current study was to measure the knee joint angle and plantar pressure distribution between hallux valgus group and normal group under jogging condition. To reveal relationship of plantar pressure distribution and knee joint angle. Investigated that lower extremity mechanics of jogging in young female with mild hallux valgus. Sixteen young, healthy females volunteered to take part in this study. Kinematic data from a three-dimensional motion analysis system and plantar pressure distribution from Pedar-X system were collected to describe lower extremity mechanics while hallux valgus subjects jogging at a natural speed. The results found that knee joint angle of hallux valgus in frontal and transverse plane was obviously different under jogging condition. In frontal plane, the initial state of adduction angle (control group (CO) = 1.73 °, hallux valgus group (HV) = 8.33 °) of two group was markedly different at the beginning of the support (0-10%). During jogging gait cycle, knee abduction angle peak of normal group was 8.46°, and knee adduction angle peak of hallux valgus group was 8.61°. In the transverse plane, knee external rotation angle in the initial state of normal group was 21.93° while knee external rotation angle of hallux valgus was 4.89°. The results of plantar pressure found that bearing pressure regions was offshore in hallux valgus group. These changes would affect the movement of knee joint, and it suggested that hallux valgus group have higher risk for knee osteoarthritis. These results also suggested that hallux valgus deformity has influence on knee joint. We cannot be ignored in the process of the research and therapeutic with hallux valgus.

Background We investigated the role of first metatarsal head shape in the etiology of hallux valgus. By pedobarographic analysis, we evaluated whether first metatarsal head shape causes an alteration in plantar pressure values that would result in metatarsalgia. Methods Referrals to our clinic for metatarsalgia, plantar fasciitis, and calcaneal spur were scanned retrospectively. Patients with severe hallux valgus, pes planus, gastrocnemius stiffness, generalized joint laxity, neuromuscular disease, or a history of lower-extremity orthopedic surgery were excluded. Sixty-two patients with plantar pressure assessment and radiographic evaluation were included. These patients were invited for reassessment after 10 years. Feet were divided into three groups by metatarsal head shape: round, square, and chevron. On anteroposterior radiographs, the hallux valgus and intermetatarsal angles, relative first metatarsal length, lateral sesamoid subluxation, and presence of bipartite sesamoid were noted. Plantar pressure was assessed with pedobarography. Results Feet with round-shaped first metatarsal heads had a statistically significantly greater progression in hallux valgus angle than the other shapes. Plantar pressures under the first, second and third, and fourth and fifth metatarsals increased with time. This can explain the mechanism of transfer metatarsalgia and painful callosities under the first metatarsal in hallux valgus. There was no correlation between hallux valgus angle, relative metatarsal length, and lateral sesamoid subluxation. Conclusions We found a strong relation between round-shaped first metatarsal head and hallux valgus angle progression. No patients had a risk factor responsible for hallux valgus. In other words, this study gives approximately 10-year natural history results in nearly normal feet.

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 (HV) is a deformity that affects the quality of life and function in a negative manner causing disturbed balance and walking and even alters the foot kinematics. Conservative treatments are the choice for mild to moderate HV, but the question about the best method has not been responded yet. In the current study, it is aimed to assess and compare the efficacy of kinesiotaping (KT) versus phonophoresis (PH) for the treatment of painful HV. Materials and Methods: This randomized clinical trial has been conducted on a total number of 37 toes (37 toes of a total number of 24 patients) randomly divided into two subgroups of either KT or PH with 1% hydrocortisone among which the total numbers of 31 toes from 20 patients fulfilled the study protocol. The variables including pain (using VAS score), function (using Manchester-Oxford Foot questionnaire)(MOXFD), hallux valgus angle (HVA), and intermetatarsal angle (IMA) were assessed and compared between two groups before and after two months following the interventions. Results: The pain score decreased significantly within the time in both groups (P-value<0.001), while the comparison of KT with PH revealed insignificant difference (P-value=0.08). MOXFD assessments showed significantly improved status within two months for both interventions (P-value<0.001) with no remarkable difference between the groups (P-value=0.55). The IMA and HVA altered following both of the techniques. KT was superior to PH for the correction of HVA, but not for IMA (P-value>0.05). Conclusion: We found both of the KT and PH techniques could successfully rehabilitate the patients’ pain and improve function, however the KT was slightly better than PH due to HVA reduction.
