RESUMO
Metatarsus adductus (MA), the most common congenital foot deformity, involves adduction of the forefoot at the tarsometatarsal joint, with normal hindfoot alignment. Early diagnosis is important because treatment is more successful if initiated before age 9 months. Treatment of MA depends on deformity severity, in which mild to moderate deformity can be treated conservatively. Current standard of care for severe or rigid deformity involves referral by primary care physicians to specialists for management by casting and splinting. Recently, several orthoses have demonstrated equal effectiveness to casting and may allow for primary care physicians to treat MA without the need for referral. In this review article, we provide an overview of MA and discuss diagnosis and treatment. We also discuss novel devices and suggest how they may affect the future management of severe and rigid MA.

INTRODUCTION: The most common foot deformity in newborns is the forefoot adduction deformity (FAD), where the hindfoot foot is in a normal position. The diagnosis for this problem is mainly based on a physical examination. The use of imaging methods has been described, but no advantage was shown with their utilization in determining the diagnosis and guiding treatment. Several classification systems have been proposed to characterize the degree of severity. The classifications are based on the degree of deviation and the flexibility of the foot. Early diagnosis and early treatment, if necessary, are extremely important to improve the chances of treatment success. Treatment depends on the severity of the deformity. For mild deformities the treatment is conservative - follow-up or stretching of the foot. The usual treatment for severe deformities is serial casting. Several orthoses have recently been proposed to address the problem and these demonstrated similar results, higher comfort and satisfaction, lower cost and a similar side effect profile. Surgical treatments to correct the deformity are reserved for cases where conservative treatment failed and for older children. This review aims to summarize the current knowledge on the subject, describe the ways to diagnose and classify the deformity, and present the variety of ways to treat the problem including the use of innovative braces. In addition, we will offer a protocol for the treatment of the deformity that is accepted in our institution. The protocol will assist primary care physicians to both diagnose and treat appropriate deformities, and know when a specialist referral is necessary.

BACKGROUND: In-toeing gait is defined as the internal rotation of the long axis of the foot to the line of progression. Although most of the time it is corrected spontaneously but sometimes causes torsional misalignment syndrome and maybe patellofemoral instability and arthritis of the knee. RESEARCH QUESTION: What is the effect of gait plate insoles and lateral sole wedged shoes on foot progression angle (FPA) in children with in-toeing? METHOD: In this study, a randomized control trial was conducted with 11 participants (18 feet) who were girls aged between seven and ten years old. They were randomly assigned to either the gait plate group (6 girls, 11 feet) or the lateral sole wedge group (5 girls, 11 feet). The foot progression angle was measured using the RS scanner pressure platform before and after four weeks of intervention, both with and without interventions. The interaction effects of time and group on outcomes were analyzed using Mixed ANOVA and post-hoc complementary tests with a confidence interval of 95%. RESULTS: It was observed that none of the interventions had an immediate impact on the FPA (P > 0.05). However, after four weeks, the FPA increased by 9.96 degrees with the lateral sole wedge and by 3.51 degrees with the gate plate insole. During the immediate and short-term evaluation, no significant difference was noticed between the two groups (P > 0.05). However, there was a large effect size (eta square = 0.269) observed in the time group interaction between the two groups (P = 0.028). SIGNIFICANCE: Conservative methods like using a gait plate insole or modifying shoes with a lateral sole wedge can improve the foot progression angle in children with in-toeing gait. However, longer studies with larger sample sizes are needed to reach a conclusion.

Hallux valgus (HV) is a common deformity of the foot. Its postoperative recurrence is not uncommon and is closely related to the recurrence of its underlying metatarsus primus varus (MPV) deformity. The syndesmosis procedure uses 1 to 2 intermetatarsal cerclage sutures to realign the first metatarsal and then induces a biological bonding between the 2 metatarsals to prevent the MPV deformity from recurring. This radiological study aimed to assess its effectiveness in long-term MPV and HV deformities recurrence prevention. Ninety-two feet of 51 consecutive patients had syndesmosis procedures that were prospectively followed up for more than 1 y and up to 14 y, averaging 100.5 (SD 45.2) months. Patients underwent X-ray examinations regularly at fixed intervals of their feet. We used Hardy's methods in measuring the intermetatarsal angle (IMA), hallux valgus angle (HVA), and medial sesamoid position from standing foot X-rays. More than 450 relevant X-ray and photo images were submitted as Supplementary Material for online viewing and reference. There was a significant final correction of IMA from 14.30° (SD 2.70) to 6.70° (SD 1.75) (p < .0001). There was no significant increase in IMA after the sixth postoperative month to their final follow-up endpoints, regardless of their lengths. There was a significant final correction of HVA from 31.95° (SD 7.45) to 19.1° (SD 7.45) (p < .0001). This study reconfirmed past findings that the MPV deformity could be corrected without osteotomies. Creating a syndesmosis-like intermetatarsal bonding was effective for long-term MPV recurrence prevention. Three feet had postoperative stress fracture of the second metatarsal. However, the HV deformity correction was less satisfactory, and the reasons were explained.

OBJECTIVES: Hallux valgus is associated with tarsometatarsal arthritis; its pathophysiology remains unknown. Therefore, we aimed to elucidate the relationship between arthritis of the second and third tarsometatarsal joints and incongruity of the first tarsometatarsal joint in the sagittal plane. METHODS: Forty-three patients (64 feet) with hallux valgus who underwent surgery at University Hospital Kyoto Prefectural University of Medicine were included and divided into two groups: control (without second and third tarsometatarsal joint degeneration) and osteoarthritis (with second and third tarsometatarsal joint degeneration). Intergroup comparisons of the incongruity of the first tarsometatarsal joint in the sagittal plane, age, body mass index, hallux valgus angle, first-second intermetatarsal angle, metatarsus adductus angle, Meary's angle, and calcaneal pitch angle were performed. RESULTS: The proportion of patients with incongruity of the first tarsometatarsal joint was significantly higher in the osteoarthritis group than in the control group. Logistic regression analysis identified incongruity of the first tarsometatarsal joint and metatarsus adductus angle as significant related factors for arthritis of the second and third tarsometatarsal joints. CONCLUSIONS: Incongruity of the first tarsometatarsal joint in the sagittal plane was involved in the development of arthritis of the second and third tarsometatarsal joints in patients with hallux valgus.

Ankle fractures are among the most common fractures sustained in the pediatric population. Given the frequency of physeal involvement of the distal fragment, complications including growth arrest, overgrowth, and rotational deformities are not uncommon. This case report describes a 12-year-old adolescent boy who presented after an acute right ankle injury sustained while playing. He noted right ankle pain, swelling, and in-toeing of his foot. Radiographs of the ankle demonstrated a distal tibia Salter-Harris type II fracture that appeared nondisplaced. However, a CT scan of the ankle demonstrated a 60° difference in the rotational profile between the injured and noninjured tibias. The patient's acute rotational deformity was corrected with closed reduction and percutaneous pinning. Pediatric distal tibia physis fractures presenting with in-toeing are rare and difficult to diagnose accurately with radiographs alone. Accordingly, a detailed history, physical examination, comparison radiographs, and CT scans are imperative in making the correct diagnosis and determining the appropriate treatment.

The research results are inconsistent that assessing whether the increased obliquity of the distal articular surface of the medial cuneiform leads to an increase in hallux valgus angle. Thus, this study investigated the relationship between distal medial cuneiform obliquity and hallux valgus by measuring various angles in weightbearing anteroposterior radiographs of the foot. In total, 679 feet of 538 patients with the radiographs were included in the study. We measured radiographic parameters including hallux valgus angle, first to second intermetatarsal angle, metatarsus adductus angle, first metatarsus cuneiform angle, distal medial cuneiform angle, and first proximal metatarsal articular angle. The surface morphology (flat or curved) of the first tarsometatarsal joint was also recorded. Our results analysis revealed a weak negative correlation between distal medial cuneiform angle and both hallux valgus angle and first to second intermetatarsal angle, contrary to our assumption. So we believe that distal medial cuneiform angle was relatively constant and it cannot be used as a characteristic angle for quantifying hallux valgus. First metatarsus cuneiform angle was a characteristic indicator of hallux valgus and was positively correlated with its severity (p < .000), indicating that it can be used to measure the size of hallux valgus. It can also be used as a reference factor for the first metatarsal osteotomy in clinical bunion orthopedics. First tarsometatarsal joint morphology was unrelated to hallux valgus, whereas metatarsus adductus angle, and first proximal metatarsal articular angle should be considered in hallux valgus.

PURPOSE: To describe a conservative treatment algorithm to manage Congenital Metatarsus Varus. BACKGROUNDS: Congenital Metatarsus Varus is a congenital disorder with an estimated incidence of 1/1000 newborns. Despite the deformity being mostly an aesthetic problem, residual and incorrect forms may be responsible for abnormal in-toe gait and shoe-wearing issues. No consensus has still been gathered regarding its correct treatment algorithm. METHODS: Between May 2019 and September 2020, 2156 newborn patients underwent an orthopedic examination at birth. Patients affected by Congenital Metatarsus Varus were classified according to Bleck's classification as flexible, semi-flexible or non-flexible deformity. A conservative treatment algorithm was followed, based on the application of manipulations, Bebax-type braces or plaster cast. All patient were followed until the clinical resolution of the deformity. Complications were also recorded. RESULTS: One-hundred twenty-four patients were diagnosed Congenital Metatarsus Varus, with an overall prevalence of 5/1000. One-hundred twenty-two patients presented with a flexible or semi-flexible foot deformity and were firstly treated with manipulations: 52 patients reported good results, while 70 required additional treatment with Bebax-type braces for achieving correction. Two patients presented a non-flexible deformity at birth: one required plaster cast due to a non-flexible deformity, and one patient was firstly managed with Bebax-type braces due to a severe semi-flexible deformity. Only two patients presented superficial skin ulcerations, healed within a week. Two patients were lost during the follow-up. CONCLUSION: An early diagnosis allowed by an orthopedic examination in all newborns may be a valid instrument to avoid Congenital Metatarsus Varus misdiagnosis. Early treatment with manipulation and orthosis resulted in good clinical outcome, with only few complications.

Caregivers are often concerned with their child's gait, especially if it deviates from the development of other children. It is common that parents and grandparents have personal memories of brace wear or orthotic use to correct rotational or alignment difference as young children. Although perceived gait differences are a source of angst for families, many are of minimal functional concern and rarely need intervention. [Pediatr Ann. 2022;51(9):e340-e345.].

PURPOSE: In the present study, we aimed to determine the relationship of HV angle with angles and measurements obtained from lateral and anteroposterior (AP) radiological images of the foot in individuals with HV. METHODS: The present study had a retrospective design, and the participants consisted of 66 female patients between the ages of 19 and 64 who applied to Orthopedics and Traumatology and were diagnosed with Hallux valgus. Metatarsus adductus angle, metatarsus primus adductus angle, hallux valgus angle, hallux interphalangeal angle, metatarsal break angle, first metatarsal protrusion distance, metatarsal width, talocalcaneal angle, AP Meary's angle were measured on AP view and calcaneal inclination angle, talar declination angle, lateral talocalcaneal angle, first metatarsal declination angle, fifth metatarsal declination angle, navicular height, lateral Meary's angle, tibiotalar angle were measured on a lateral radiograph. The IBM SPSS 21.0. program was used for statistical analysis, and the level of significance was taken as p < 0.05. RESULTS: There were statistically significant differences between the right and left feet in MPA and AMA measurements. The results showed that HV angle (HVA) had a weak relationship with MAA and MW, as well as a moderately positive relationship with MPA. However, it had a moderately negative relationship with AMA and a weak negative relationship with HIPA. CONCLUSION: We believe that in addition to the HVA angle, MPA and AMA angles should be considered in the diagnosis of HV, especially as the HVA angle is moderately positively correlated with the MPA angle and moderately negatively correlated with the AMA angle.

BACKGROUND: This study proposes a treatment algorithm based on the correction of symptomatic metatarsus adductus (MA) associated with hallux abducto-valgo (HAV) through tarsometatarsal joint 2-3 (TMTJ) shortening arthrodesis. Our hypothesis is that the proposed algorithm leads to realignment of the forefoot rays from two to five and reduction of the talonavicular coverage angle (TNCA) with good clinical and radiographic results. METHODS: Clinical and radiographic evaluations were performed before and after surgery at 1-year follow-up on forty-six consecutive adult patients with MA, midfoot pain, HAV and osteoarthritis and/or instability of the TMTJ 2-3 in whom shortening of the 2nd and 3rd TMT joints according to MAA and treatment of the HV according to deformity was undertaken. RESULTS: Talus-first metatarsal angle (TFMA) was the only parameter which did not statistically significantly postoperatively change. All other clinical (AOFAS score) and radiological outcomes significantly improved postoperatively. CONCLUSION: Although further studies are needed to confirm the proposed data, it would seems that the shortening arthrodesis of rays two and three has consequences on the forefoot and hindfoot by realigning the longitudinal axis of the foot. The consequent application of the algorithm and adequate correction of the HAV allow good clinical and radiographic results to be obtained. LEVEL OF EVIDENCE: IV prospective cases series.

Foot progression angle (FPA) analysis is one of the core methods to detect gait pathologies as basic information to prevent foot injury from excessive in-toeing and out-toeing. Deep learning-based object detection can assist in measuring the FPA through plantar pressure images. This study aims to establish a precision model for determining the FPA. The precision detection of FPA can provide information with in-toeing, out-toeing, and rearfoot kinematics to evaluate the effect of physical therapy programs on knee pain and knee osteoarthritis. We analyzed a total of 1424 plantar images with three different You Only Look Once (YOLO) networks: YOLO v3, v4, and v5x, to obtain a suitable model for FPA detection. YOLOv4 showed higher performance of the profile-box, with average precision in the left foot of 100.00% and the right foot of 99.78%, respectively. Besides, in detecting the foot angle-box, the ground-truth has similar results with YOLOv4 (5.58 ± 0.10° vs. 5.86 ± 0.09°, p = 0.013). In contrast, there was a significant difference in FPA between ground-truth vs. YOLOv3 (5.58 ± 0.10° vs. 6.07 ± 0.06°, p < 0.001), and ground-truth vs. YOLOv5x (5.58 ± 0.10° vs. 6.75 ± 0.06°, p < 0.001). This result implies that deep learning with YOLOv4 can enhance the detection of FPA.

This study aims to assess a novel minimally invasive surgical technique that addresses hallux valgus accompanied by metatarsus adductus. We retrospectively analysed the results of 20 patients (21 feet) that underwent a newly developed percutaneous osteotomy procedure of the lesser metatarsal bones in order to correct hallux valgus deformities accompanied by metatarsus adductus. We used x-ray studies in order to evaluate changes in the hallux valgus angle, the first intermetatarsal angle, and the metatarsal angle (using the modified Sgarlato method). We also compared the pre- and postoperative American Orthopaedic Foot and Ankle Society scores when available. The paired sample t test was used to compare variables. At a 1-y follow-up the mean hallux valgus angle, inter-metatarsal angle and the metatarsal angle have been reduced by 31.62 (-3 to 9), 3.86 (11-52) and 14.69 (4-36) respectively (p < .001 for all). The mean American Orthopaedic Foot and Ankle Society score (n = 15 feet available) has been improved by a mean of 44.53 (22-72, p < .001). In addition, the patient satisfaction rates were high. Patients suffered from mild to moderate midfoot pain during the first few weeks following surgery, which resolved when union occurred. No cases of lesser metatarsal nonunion have been documented. The presented minimally invasive method can be used effectively to correct hallux valgus that is associated with metatarsus adductus. Proximal minimally invasive metatarsal osteotomy can effectively correct hallux valgus accompanied by metatarsus adductus.

BACKGROUND: Slipped capital femoral epiphyses (SCFE) is associated with out-toeing of the foot and external rotation gait. But it is unknown if SCFE patients treated with the modified Dunn procedure have out-toeing at follow up.Therefore, we used instrumented gait analysis and questioned (1) do severe SCFE patients treated with a modified Dunn procedure have symmetrical foot progression angle (FPA) compared with contralateral side and compared with asymptomatic volunteers (2) what is the prevalence of out-toeing gait and what are the outcome socres at follow up. METHODS: Gait analysis of 22 patients (22 hips) treated with an unilateral modified Dunn procedure for severe SCFE (slip angle >60 degrees, 2002 to 2011) was retrospectively evaluated. Of 38 patients with minimal 5-year follow up, 2 hips (4%) had avascular necrosis of the femoral head and were excluded for gait analysis. Twenty-two patients were available for gait analysis at follow up (mean follow up of 9±2 y). Mean age at follow up was 22±3 years. Mean preoperative slip angle was 64±8 degrees (33% unstable slips) and decreased postoperatively (slip angle of 8±4 degrees). Gait analysis was performed with computer-based instrumented walkway system (GAITRite) to measure FPA with embedded pressure sensors. Patients were compared with control group of 18 healthy asymptomatic volunteers (36 feet, mean age 29±6 y). RESULTS: (1) Mean FPA of SCFE patients (3.6±6.4 degrees) at follow up was not significantly different compared with their contralateral side (5.6±5.5 degrees) and compared with FPA of controls (4.0±4.5 degrees). (2) Of the 22 SCFE patients, most of them (19 hips, 86%) had normal FPA (-5 to 15 degrees), 2 patients had in-toeing (FPA<-5 degrees) and 1 had out-toeing (FPA >15 degrees) and was not significantly different compared with control group. (3) Mean modified Harris hip score (mHHS) was 93±11 points, mean Hip Disability and Osteoarthritis Outcome Score (HOOS) score was 91±10 points. Three patients (14%) had mHHS <80 points and walked with normal FPA. The 2 patients with in-toeing and one patient with out-toeing had mHHS >95 points. CONCLUSIONS: Patients with severe SCFE treated with modified Dunn procedure had mostly symmetrical FPA and good hip scores at long term follow up. This is in contrast to previous studies. Although 1 patient had out-toeing and 2 patients had in-toeing at follow up, they had good hip scores. LEVEL OF EVIDENCE: Level III-retrospective comparative study.

OBJECTIVE: To investigate the relationship between hallux valgus and the indicators associated with medial cuneiform obliquity measured on feet weight-bearing anteroposterior X-ray films. METHODS: Based on the feet weight-bearing anteroposterior X-ray films taken between January 2018 and February 2021 and met the criteria, the hallux valgus angle (HVA), intermetatarsal angle (IMA), metatarsus adductus angle (MAA), metatarsus cuneiform angle (MCA), distal medial cuneiform angle (DMCA), and proximal metatarsal articular angle (PMAA) were measured and the morphology of the first tarsometatarsal (TMT) were recorded. According to the HVA, the X-ray films were divided into normal group (HVA<15°) and hallux valgus group (HVA≥15°). The gender, age, sides, IMA, MAA, MCA, DMCA, PMAA, and the morphology of TMT were compared between groups. The influencing factors of HVA and IMA were analyzed by multivariate linear regression analysis. RESULTS: X-ray films of 534 patients (679 feet) met the selection criteria and were included in the study. There were 220 males and 314 females, with an average age of 36 years (mean, 18-82 years). There were 154 cases (168 feet) in the normal group and 403 cases (511 feet) in the hallux valgus group. There were significant differences in gender and age between groups ( P<0.05), and no significant difference in the side ( P>0.05). The IMA, MAA, and MCA in the hallux valgus group were significantly bigger than those in the normal group ( P<0.05); the difference in DMCA between the two groups was not significant ( P>0.05). The TMT morphology of the two groups was mainly curved, and the difference in morphology classification was not significant ( P>0.05). PMAA measurement showed that there were 3 kinds of metatarsal shapes: adductive metatarsal, neutral metatarsal, and abductive metatarsal, the difference in metatarsal shapes between groups was not significant ( P>0.05). The PMAA of abductive metatarsal was significantly bigger in normal group than in hallux valgus group ( P<0.05), there was no significant difference in PMAA of adductive metatarsal between groups ( P>0.05). Multivariate linear regression analysis showed that age, MCA, and DMCA were the influencing factors of HVA ( P<0.05), and age, MAA, MCA, and DMCA were the influencing factors of IMA ( P<0.05). CONCLUSION: The medial cuneiform obliquity is relatively constant and the DMCA can not be used as the characteristic angle to quantify hallux valgus. The morphology of TMT has no relationship with hallux valgus, while MAA, MCA, and PMAA are all factors to be considered, and MCA can be used as the characteristic angle to quantify hallux valgus.

There are various treatment approaches for the subjects with metatarsus adductus, including nonsurgical and surgical treatment. Nonsurgical treatments such as serial casting, modified shoes (Bebax shoe, Ipos antiadductus shoe) and orthoses (Wheaton brace, counter rotation system splint, Denis Brown bar, and Fillauer bar) are widely used in this regard. The main question posted here is which orthoses are more effective in correcting metatarsus adductus. Therefore, the aim of this review was to determine the efficiency of various nonsurgical treatments used for metatarsus adductus. MEDLINE/PubMed, EMBASE, Cochrane Central Register of Controlled Trial, Cochrane Data base of systematic review (CDSR), Scopus and ISI Web of knowledge (from 1960 to 2021) were searched by predefined search strategies to screen eligible randomized controlled studies meeting established criteria. The quality of the studies was assessed based on Down and Black tool. 200 studies on this topic were reviewed and finally 11 studies which met the inclusion criteria were selected for final analysis. These studies evaluated the efficiency of nonsurgical treatment options on foot angle and deformity correction in the subjects with metatarsus adductus. Quality of the papers based on Downs and Black tool varied between 13 and 23. Some treatments such as Wheaton brace, rigid strap, exercise (manipulation), reverse last shoe and plaster cast are used for these subjects. Although good correction can be achieved with use of these treatment methods, some of them have complications which should be considered in this regard. It seems that Wheaton brace and Bebax shoe have fewer complications compared to other methods.

The origin of fractures of the fifth metatarsus and Jones fracture is not clear. The goal of this study was to investigate the evidence of anatomical deformities such as metatarsus adductus, hindfoot varus, or pes cavus as risk factors for this pathology. A literature search of records related to the review question was performed screening PubMed/Medline, Embase and Cochrane library databases (last update: May 2020) according to PRISMA guidelines. A meta-analysis was performed using the mean difference of the assessed angles (in patients with the fractures vs controls) as outcome measure to summarize literature findings about metatarsus adductus angle (MAA) indicating forefoot adduction, calcaneal pitch angle (CP) indicating hindfoot cavus and varus deformity and Talo-1st metatarsus angle/Meary's angle (T1stMA) for varus alignment. Eight studies were included in the qualitative analysis (296 patients), 5 in the quantitative synthesis (132 patients). The pooled mean difference of MAA between fracture versus control group on a per patient-based analysis was 4.62 (95% CI 1.31-7.92). Statistical heterogeneity among studies was detected (I-Square: 76.1%), likely due to different patient groups and low number of studies. The pooled mean differences of CP and T1stMA among fracture group versus controls did not show statistical significance. Despite limited literature data, metatarsus adductus deformity seems to be correlated with higher risk of proximal metatarsal fractures and Jones fracture. A significant relationship between hindfoot varus or pes cavus and these fractures was not demonstrated. Further studies and trials are warranted to shed more lights on this topic.

BACKGROUND: Many authors have highlighted the role of muscle strength imbalance around the ankle in the development of recurrent clubfoot following Ponseti treatment. However, this possible underlying mechanism behind recurrence has not been investigated sufficiently to date. This study aimed to explore whether there is a relationship between Achilles tendon elongation and recurrent metatarsus adductus deformity in children with unilateral clubfeet treated by the Ponseti method. METHODS: A retrospective chart review was performed on 20 children (14 boys and six girls; mean age, 7 years; age range, 5-9 years) with a recurrent metatarsus adductus deformity treated by the Ponseti method for unilateral idiopathic clubfoot. At the final follow-up, isometric muscle strength was measured using a portable, hand-held dynamometer in reciprocal muscle groups of the ankle. The length of the tendons around the ankle was measured ultrasonographically. RESULTS: The plantarflexion-to-dorsiflexion ratio was lower on the involved side (P = .001). No significant differences in the strength ratio of inversion to eversion were found (P = .4). No difference was observed in lengths of tibialis anterior and posterior tendons (P = .1), but the Achilles tendon was longer on the involved side (P = .001; P < .01). A significant negative correlation was discovered between involved-to-uninvolved Achilles tendon length ratios and involved-to-uninvolved plantarflexion strength ratios (r = -0.524; P = .02) Conclusions: Achilles tendon elongation may be a contributor to the muscle imbalance in clubfeet with relapsed forefoot adduction treated by the Ponseti technique.

Metatarsus adductus and hallux valgus are common foot deformities. Corrective surgery of hallux valgus feet with metatarsus adductus deformity can be challenging and experience a high deformity recurrence rate. The purpose of this study was to demonstrate if the syndesmosis procedure can correct such feet satisfactorily without osteotomies and arthrodesis. 75 hallux valgus feet in 45 patients with a Sgarlato's metatarsal adductus angle ≥15° were studied after having undergone the syndesmosis procedure for an average of 20.22 months. Their average preoperative intermetatarsal angle of 12.56° was improved to 6.00° (p < .001) and metatarsophalangeal angle from 35.61° to 23.46° (p < .001) significantly. Their average American Orthopedic Foot and Ankle Society's clinical scores improved significantly from 56.41 to 90.53 points (p < .001). Fifty-five feet (73.33%) had preoperative metatarsal calluses, and all but 3 had a noticeable reduction in severity. Forty-one patients (91.11%) were able to return to their desired activities and footwear. All relevant raw data formed this study, including x-ray and photographic images, were submitted as Supplementary Material for online viewing and reference. Despite the possible intrinsic rigidity of metatarsus adductus forefoot, this study demonstrated that hallux valgus feet with metatarsus adductus deformity could be corrected anatomically and functionally with the soft tissue syndesmosis procedure and without correcting the preexisting metatarsus adductus deformity. This study also supports the notion that the MA deformity accentuates hallux valgus alignment preoperatively and postoperatively, and possibly all feet in general.

Forefoot adduction deformity (FAD) (commonly called metatarsus adductus) is reported as the most common congenital foot deformity in newborns. Early diagnosis and treatment are important in rigid cases, as better outcomes have been reported if treatment was initiated before 9 months of age. While casting and splinting is the current standard of care for nonsurgical management of rigid FAD (RFAD), several orthoses have demonstrated equal benefit. The Universal Neonatal Foot Orthotic (UNFO) brace is below ankle orthosis that provides continuous pressure, thereby correcting the deformity without casting. To the best of our knowledge, UNFO is the first brace that operates below the ankle. The aim of this study was to compare the effectiveness of UNFO shoe to standard serial casting in the treatment of RFAD in infants. Between the years 2012 and 2019 we treated 147 feet (94 patients): 52 using the UNFO shoes and 95 by standard casting and splinting protocol. The treatment groups were compared based on treatment duration, complications, and recurrence of deformity. Mean full-time treatment duration was significantly shorter in the UNFO group, while no significant difference in the total duration of treatment was observed. Similar complication and recurrence rates were demonstrated. In conclusion, treatment with UNFO is equally effective to serial casting. The use of UNFO increases convenience and diminishes social burden, thus providing a distinct advantage over other treatment modalities.
