Abstract
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.

[PMID: 37419765 DOI: 10.1016/j.fas.2023.06.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/27/2022] [Revised: 05/27/2023] [Accepted: 06/24/2023] [Indexed: 07/09/2023]
Abstract
BACKGROUND Among the numerous surgical interventions for correcting hallux valgus deformity in skeletally immature patients, hemiepiphysiodesis is a simple technique with a low complication rate yet its effectiveness remains unclear. This systematic review evaluates hemiepiphysiodesis of the first metatarsal for treating juvenile hallux valgus (JHV) deformities with respect to radiological outcomes, postoperative clinical outcomes, and postoperative complications. METHODS EMBASE, MEDLINE, PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), and Cumulative Index to Nursing and Allied Health Literature (CINAHL) database were searched from inception to September 15th, 2022, for studies investigating hemiepephysiodesis for JHV and its effect on clinical and radiological outcomes. The search, data extraction and methodologic assessment were performed in duplicate for all included studies. RESULTS Six studies out of 488 with a total of 147 feet in 85 patients were included in the final qualitative synthesis. The American Orthopaedic Foot & Ankle Society hallux metatarsophalangeal interphalangeal scale (AOFAS Hallux MTP-IP scale) was used in two studies. The mean pooled preoperative score was 62.2 ± 8.9 and improved to 88.6 ± 4.8 postoperatively in 33 patients. All six studies reported significant improvement in the hallux valgus angle (HVA) from mean preoperative angle of 29.2° ± 3.7-23.8° ± 4.5° postoperatively, while the intermetatarsal angle (IMA) preoperative and postoperative means corrected from 13.9° ± 1.1-11.4° ± 1.2°, respectively. Out of 147 feet, 21 (14.2%) had reported complications including recurrence and need for revision surgery. CONCLUSION This systematic review confirms that hemiepiphysiodesis of the first metatarsal in patients with JHV has improved clinical and radiological outcomes. LEVEL OF EVIDENCE Level IV, Systematic review.

Abstract
BACKGROUND No evidence has been found to support the hypothesis that there is a correlation between hallux valgus (HV) and intermetatarsal (IM) angles in HV with metatarsus adductus (MA) and that IM angle in HV with MA is lower than that in HV without MA. The present study aimed to analyze the radiographic characteristics of HV with MA compared to matched controls and to clarify the differences between HV with MA and without MA. METHODS Preoperative radiographs of 126 female patients (164 feet) who underwent hallux valgus surgery were reviewed. The HV, IM, and MA angles were measured. The MA was defined as MA angle of 20° or greater. Of all the feet, 37 (22.6%) had HV with MA (MA group). Control A (111 feet) having HV without MA was matched by age, gender, and BMI to MA group; Control B (79 feet) having HV without MA was matched by age, gender, BMI, and HV angle to the sub-MA group (31 feet) having HV with MA. RESULTS The correlation coefficient between the HV and IM angles in the MA group was considered negligible (r = 0.08, p = 0.63), whereas the correlation coefficient in Control A was considered moderate (r = 0.57, p < 0.00001). The correlation coefficient in the MA group was significantly smaller than in Control A (p < 0.01). There was no significant difference in the HV angle between the sub-MA group and Control B (p = 0.23), but the IM angle was significantly smaller than in Control B (p = 0.002). CONCLUSION There is no significant correlation between the HV and IM angles in HV with MA, as there is in HV without MA. HV with MA has a significantly smaller IM angle for the HV angle compared to HV without MA.

Abstract
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.

Abstract
Treatment of juvenile hallux valgus can be challenging. Initial treatment with conservative measures is appropriate until exhausted. Surgical treatment should be delayed until after skeletal maturity when possible. Before any intervention, a thorough understanding of the whole patient and any underlying systemic contributors to their hallux valgus, in addition to the radiographic foot parameters, is imperative. Careful and individualized surgical planning should be done to optimize results and decrease the risk for recurrence.

Abstract
Metatarsus adductus is common clinical entity with an estimated prevalence of approximately 30%. Multiple radiographic methods exist to evaluate the extent of the deformity, with the Sgarlato and Engel methods most commonly used. Surgical treatment varies, consisting of proximal versus distal metatarsal osteotomies, TMT arthrodesis, and realignment of the lesser rays. Particularly in severe cases, addressing all deformities is critical to obtaining a good outcome.

Abstract
BACKGROUND Operative treatment is indicated for patients who have symptomatic hallux valgus (HV) with moderate to severe metatarsus adductus (MA). However, there is limited information available on the operative procedures and outcomes for the treatment of HV with MA. We aimed to investigate the average 10-year follow-up clinical and radiologic outcomes. METHODS Seventeen patients (21 feet, average age: 60.1 years) with symptomatic HV with moderate to severe MA were operatively treated. Mean postoperative follow-up duration was 114.4 (24-246) months. All feet had metatarsus adductus angle ≥20 degrees on dorsoplantar weight-bearing radiograph. The procedure included a proximal crescentic osteotomy of the first metatarsal and abduction osteotomy of the proximal third of the second and third metatarsals. RESULTS The mean American Orthopaedic Foot & Ankle Society scale score improved significantly postoperatively ( P < .001). The mean postoperative visual analog scale score (17 feet) was 2.0 (0-6). Preoperative metatarsalgia was severe in 2 feet, moderate in 17, and mild in 2. At the most recent follow-up evaluation, 11 feet had no pain, 9 had mild pain, and 1 had moderate pain. The mean hallux valgus angle, intermetatarsal angle, and metatarsus adductus angle significantly decreased postoperatively ( P < .001 for all). Recurrence of HV (HV angle ≥ 20 degrees) was observed in 4 feet. CONCLUSION The clinical and radiologic results indicated that our novel operative treatment for HV with moderate to severe MA can achieve significant correction of HV with MA deformities and significant improvement in pain and function.

Abstract
BACKGROUND Metatarsus adductus is a common congenital foot deformity. Variable prevalence values were reported using different techniques in different populations. Numerous radiological measurements have been proposed to assess this deformity with a paucity of studies reporting the reliability of these methods. The metatarsus adductus angle was shown to correlate with the severity of hallux abductovalgus in normal feet and preselected populations of juvenile hallux valgus. MATERIALS AND METHODS Weight bearing dorsoplantar radiographs of 150 feet were examined for 5 angles commonly used in assessing metatarsus adductus: angle between the second metatarsus and the longitudinal axis of the lesser tarsus (using the 4th or 5th metatarso-cuboid joint as a reference), Engel's angle and modified Engle's angle. The prevalence of metatarsus adductus was assessed according to published criteria for different techniques. Inter and intra-observer reliabilities of these angles were evaluated on 50 X-rays. Linear regression tests were used to assess the correlation between hallux valgus and different angles used in assessing metatarsus adductus. RESULTS Intraclass correlation coefficients were high for intra- as well as inter-observer reliability for the 5 angles tested. Prevalence of metatarsus adductus ranged (45-70%) depending on the angle used in the same population. Only the metatarsus adductus angle using the 4th metatarso-cuboid joint as a reference demonstrated significant correlation between metatarsus adductus and hallux abductovalgus angles. CONCLUSION Five techniques commonly used in assessing metatarsus adductus demonstrated high inter and intra-observer reliability values. Prevalence of metatarsus adductus and the correlation between the severity of this deformity and hallux valgus angle is sensitive to the assessment method.

Abstract
Metatarsus adductus is the most common congenital foot abnormality. Whilst there is a growing body of evidence describing many aspects of this condition, basic questions regarding aetiology, management and treatment remain controversial. Diagnosis is achieved with clinical and radiological examination. The latter is particularly important for the diagnosis of mild cases. An extensive literature review is presented outlining the development of various radiological methods of angular measurement used in the diagnosis and classification of metatarsus adductus. In addition, the review highlights a spectrum of values obtained for each angle and the validity were reported.

Abstract
The first ray is an inherently unstable axial array that relies on a fine balance between its static (capsule, ligaments, and plantar fascia) and dynamic stabilizers (peroneus longus and small muscles of the foot) to maintain its alignment. In some feet, there is a genetic predisposition for a nonlinear osseous alignment or a laxity of the static stabilizers that disrupts this muscle balance. Poor footwear plays an important role in accelerating the process, but occupation and excessive walking and weight-bearing are unlikely to be notable factors. Many inherent or acquired biomechanical abnormalities are identified in feet with hallux valgus. However, these associations are incomplete and nonlinear. In any patient, a number of factors have come together to cause the hallux valgus. Once this complex pathogenesis is unraveled, a more scientific approach to hallux valgus management will be possible, thereby enabling treatment (conservative or surgical) to be tailored to the individual.

Abstract
Metatarsus adductus is a structural foot deformity that is rarely associated with hallux valgus deformity. Surgical treatment is challenging, and multiple osteotomies are often required to correct both deformities. However, surgical impact must be considered, especially in elderly patients. We present a clinical case of a 76-year-old woman affected by hallux valgus and metatarsus adductus deformity. Multiple distal oblique osteotomies were performed on the first, second, and third metatarsals, coupled with Z-lengthening of the extensor digitorum longus tendons.

Abstract
Background The severity of hallux valgus is easily appreciated by its clinical appearance, however x-ray measurements are also frequently used to evaluate the condition, particularly if surgery is being considered. There have been few large studies that have assessed the validity of these x-ray observations across a wide spectrum of the deformity. In addition, no studies have specifically focused on older people where the progression of the disorder has largely ceased. Therefore, this study aimed to explore relationships between relevant x-ray observations with respect to hallux valgus severity in older people. Methods This study utilised 402 x-rays of 201 participants (74 men and 127 women) aged 65 to 94 years. All participants were graded using the Manchester Scale - a simple, validated system to grade the severity of hallux valgus - prior to radiographic assessment. A total of 19 hallux valgus-related x-ray observations were performed on each set of x-rays. These measurements were then correlated with the Manchester Scale scores. Results Strong, positive correlations were identified between the severity of hallux valgus and the hallux abductus angle, the proximal articular set angle, the sesamoid position and congruency of the first metatarsophalangeal joint. As hallux valgus severity increased, so did the frequency of radiographic osteoarthritis of the first metatarsophalangeal joint and a round first metatarsal head. A strong linear relationship between increased relative length of the first metatarsal and increased severity of hallux valgus was also observed. Conclusions Strong associations are evident between the clinical appearance of hallux valgus and a number of hallux valgus-related x-ray observations indicative of structural deformity and joint degeneration. As it is unlikely that metatarsal length increases as a result of hallux valgus deformity, increased length of the first metatarsal relative to the second metatarsal may be a contributing factor to the development and/or progression of hallux valgus.

Abstract
BACKGROUND The purpose of the study was to preoperatively evaluate the demographics, etiology, and radiographic findings associated with moderate and severe hallux valgus deformities in adult patients (over 20 years of age) treated operatively over a 33-month period in a single surgeon's practice. METHODS Patients treated for a hallux valgus deformity between September, 1999, and May, 2002, were identified. Patients who had mild deformities (hallux valgus angle < 20 degrees), concurrent degenerative arthritis of the first metatarsophalangeal joint, inflammatory arthritis, recurrent deformities, or congruent deformities were excluded. When enrolled, all patients filled out a standardized questionnaire and had a routine examination that included standard radiographs, range of motion testing, and first ray mobility measurement. A chart review and evaluation of preoperative radiographs were completed on all eligible patients. RESULTS One-hundred and three of 108 (96%) patients (122 feet) with a diagnosis of moderate or severe hallux valgus (hallux valgus angle of 20 degrees or more)(70) qualified for the study. The onset of the hallux valgus deformity peaked during the third decade although the distribution of occurrence was almost equal from the second through fifth decades. Twenty-eight of 122 feet (23%) developed a deformity at an age of 20 years or younger. Eighty-six (83%) of patients had a positive family history for hallux valgus deformities and 87 (84%) patients had bilateral bunions. 15% of patients in the present series had moderate or severe pes planus based on a positive Harris mat study. Only 11% (14 feet) had evidence of an Achilles or gastrocnemius tendon contracture. Radiographic analysis found that 86 of 122 feet (71%) had an oval or curved metatarsophalangeal joint. Thirty-nine feet (32%) had moderate or severe metatarsus adductus. A long first metatarsal was common in patients with hallux valgus (110 of 122 feet; 71%); the mean increased length of the first metatarsal when compared to the second was 2.4 mm. While uncommon, the incidence of an os intermetatarsum was 7% and a proximal first metatarsal facet was 7%. The mean preoperative first ray mobility as measured with Klaue's device was 7.2 mm. 16 of 22 (13%) feet were observed to have increased first ray mobility before surgery. CONCLUSIONS The magnitude of the hallux valgus deformity was not associated with Achilles or gastrocnemius tendon tightness, increased first ray mobility, bilaterality or pes planus. Neither the magnitude of the preoperative angular deformity nor increasing age had any association with the magnitude of the first metatarsophalangeal joint range of motion. Constricting shoes and occupation were implicated by 35 (34%) patients as a cause of the bunions. A familial history of bunions, bilateral involvement, female gender, a long first metatarsal, and an oval or curved metatarsophalangeal joint articular surface were common findings. Increased first ray mobility and plantar gapping of the first metatarsocuneiform joint were more common in patients with hallux valgus than in the general population (when compared with historical controls).

Abstract
BACKGROUND The aim of this study was to determine whether excessive medial deviation of the first metatarsal (excessive intermetatarsal angle) is present in the initial phase of hallux valgus. METHODS The intermetatarsal angle between the first and second metatarsals (1-2 IMA) was radiographically studied in 49 normal feet and in 49 feet with mild hallux valgus deformity. RESULTS The results demonstrated a statistically significant difference in the mean intermetatarsal angle between the two groups (8.76 degrees in normal feet; 9.98 degrees in affected feet). However, we believe that is not clinically significant. Other authors, comparing the 1-2 IMA in patients with or without more advanced hallux valgus, reported greater differences than those obtained in this study. CONCLUSIONS Excessive medial deviation of the first metatarsal is not a causal factor but rather a consequence of hallux valgus deformity.

Abstract
The purpose of this study was to investigate radiographic measurements in a cohort of patients with juvenile hallux valgus (with a hallux valgus angle > 15 degrees ) using standardized weightbearing x-rays compared with an age-matched control group. First metatarsal protrusion distance, metatarsus primus adductus angle, metatarsus adductus, first metatarsal cuneiform angle, calcaneal inclination angle, and talocalcaneal angles were assessed with discriminant functional analysis. A total of 37 sets of data were analyzed from patients with a mean age of 13.45 +/- 1.75 years. The study identified 2 significant components of juvenile hallux valgus: a positive first metatarsal protrusion distance (P <.001) and metatarsal primus adductus angle (P = .002). Discriminant functional analysis was then used to determine the best predictors of juvenile hallux valgus. This analysis allowed only 1 variable, metatarsal protrusion distance, as a predictor of whether juvenile hallux valgus was present (P < .001), with 94.3% accuracy. This study showed that a positive metatarsal protrusion distance is a significant component of juvenile hallux valgus.

Abstract
An in vivo method of labeling white cells that diagnoses diabetic pedal osteomyelitis safely, rapidly, and accurately is desirable. The objectives of this investigation were to evaluate a technetium-99m-labeled monoclonal antigranulocyte antibody for diagnosing diabetic pedal osteomyelitis, compared with indium-111-labeled leukocyte and 3-phase bone imaging for this purpose. Twenty-five diabetic patients with pedal ulcers, 22 in the forefoot and 3 in the midfoot, underwent antibody, indium-111-labeled leukocyte, and technetium-99m methylene diphosphonate 3-phase bone imaging. The 1-hour antibody, 24-hour labeled leukocyte, and 3-phase bone images were interpreted separately for the presence of osteomyelitis. The antibody and labeled leukocyte images also were interpreted together with the bone images to determine if the combined study was more accurate than each individual study. There were 10 cases of osteomyelitis among the 25 patients. The sensitivity, specificity, and accuracy of the antibody were.90,.67, and.76, respectively. These results were not significantly different from those obtained with labeled leukocyte imaging:.80,.67, and.72, respectively. The antibody was significantly more specific (P =.004) than 3-phase bone imaging (.27). Interpreting the antibody together with the bone scan did not alter the results. When interpreted with the bone images, the accuracy of labeled leukocyte imaging improved from.72 to.80. This was not significantly more accurate than either the antibody or labeled leukocyte imaging alone. The data suggest that the monoclonal antigranulocyte antibody is comparable with in vitro labeled leukocyte imaging for diagnosing pedal osteomyelitis in diabetic patients, and warrants further investigation in a larger population.

Abstract
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 degrees and the average correction of the 1-2 intermetatarsal angle was 5.3 degrees. 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 degrees. With a congruent joint, the average DMAA was 15.3 degrees. 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 degrees for a long first metatarsal and 6.0 degrees 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).
