Functional, clinical, and radiological outcomes of split anterior tibial tendon transfers in patients with sequelae of congenital talipes equinovarus. EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2024:10.1007/s00590-024-03994-8. [PMID: 38772958 DOI: 10.1007/s00590-024-03994-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/02/2024] [Accepted: 05/08/2024] [Indexed: 05/23/2024]
Abstract
OBJECTIVE This retrospective analysis aimed to assess the effectiveness of Split Tibialis Anterior Tendon Transfer (Split TATT) in treating residual idiopathic congenital talipes equinovarus (CTEV) deformities. METHODS 15 patients (20 feet) with CTEV, with a mean age of 6.4 ± 3.2 years, initially treated with Ponseti casting, underwent Split TATT. Clinical and radiological evaluations, including Diméglio and Garceau scores, dorsiflexion, and X-ray measurements, were conducted preoperatively and post-operatively at a minimum 2-year follow-up. RESULTS Significant improvements were observed in Diméglio and Garceau scores. Dorsiflexion increased by an average of 3°, and radiological analysis revealed nuanced changes. Despite a weak Kappa coefficient, positive trends in dorsiflexion and Garceau scores were noted. Preoperative Garceau scores did not reliably predict postoperative results. CONCLUSION Split TATT demonstrates promising results in improving muscular balance and functional outcomes in CTEV. While radiological changes are subtle, positive trends in clinical scores indicate meaningful outcomes. LEVEL OF EVIDENCE IV Retrospective study.

Relationship between arthritis of the second and third tarsometatarsal joints and incongruity of the first tarsometatarsal joint in patients with hallux valgus. Mod Rheumatol 2024; 34:410-413. [PMID: 36688576 DOI: 10.1093/mr/road009] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Revised: 12/12/2022] [Accepted: 01/04/2023] [Indexed: 01/24/2023]
Abstract
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.

Muscle activation while running on the ground compared to artificial turf in males with pronated and supinated feet. Gait Posture 2024; 107:306-311. [PMID: 37914560 DOI: 10.1016/j.gaitpost.2023.10.020] [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: 02/03/2023] [Revised: 09/15/2023] [Accepted: 10/25/2023] [Indexed: 11/03/2023]
Abstract
BACKGROUND Running on different surfaces, including natural and artificial surfaces, requires different gait mechanics, especially in individuals with foot deformity. RESEARCH QUESTION How muscle activity change during running on the ground and artificial turf in males with pronated and supinated feet? METHODS In this quasi-experimental study, we assessed a cohort of young male subjects, classified as healthy (n = 10), and with pronated (n = 10) or supinated (n = 10) feet. An electromyographic system was used to record lower limb muscle activity while running on the ground and artificial turf at constant speed (3.2 m/s). RESULTS Results demonstrated significant main effects of the "surface" factor for vastus medialis activity during the loading phase (p = 0.040, η2 =0.147). Paired comparison revealed significantly greater vastus medialis activity while running on artificial grass with respect to the ground. A significant effect of the "group" factor was found for medial gastrocnemius during loading phase (p = 0.020, η2 =0.250). Paired-wise comparison revealed significantly lower medial gastrocnemius activity in the pronated and supinated feet groups than in the healthy group. SIGNIFICANCE The healthy group may possess better neuromuscular control, allowing them to effectively coordinate the activation of the medial gastrocnemius with other muscles involved in running. Based on these findings, running on artificial turf is useful when the runner would like to strengthen vastus medialis muscle. The runner should carefully choose the running surface according to his/her state and training session goal.

Abstract
Early-onset ataxias are often difficult to diagnose due to the genetic and phenotypic heterogeneity of patients. Whole exome sequencing (WES) is a powerful method for determining causative mutations of early-onset ataxias. We report a case in which a novel de novo KIF1A mutation was identified in a patient with ataxia, intellectual disability and mild foot deformity.A patient presented with sporadic forms of ataxia with mild foot deformity, intellectual disability, peripheral neuropathy, pyramidal signs, and orthostatic hypotension. WES was used to identify a novel de novo mutation in KIF1A, a known causative gene of neurodegeneration and spasticity with or without cerebellar atrophy or cortical visual impairment syndrome (NESCAVS).We report a novel phenotype of NESCAVS that is associated with a novel de novo missense mutation in KIF1A, which provides valuable information for the diagnosis of NESCAVS even in the era of WES. Early rehabilitation of patients with NESCAVS may prevent symptom worsening and improve the disease course.

Abstract
INTRODUCTION Diabetes foot deformity is among the major causes of diabetic foot ulceration, resulting in lower limb amputation. However, the study on the distribution of foot deformity and its risk factor among diabetic patients in Ethiopia is limited. This study determined the overall prevalence and associated factors of foot deformity among adult diabetic patients on follow-up at Debre Markos Comprehensive Specialized Hospital, Northwest Ethiopia. METHODS Hospital-based cross-sectional study was conducted among 392 diabetic patients using a systematic random sampling technique at Debre Markos Comprehensive Specialized Hospital. Data were collected by pre-tested, semi-structured questionnaires and diabetic foot assessment format. Multivariable binary logistic regression was used to determine the association between dependent and independent variables. Adjusted odds ratios (AOR) with their 95% confidence interval (CI) were used to determine the strength of the association, and a variable with a p-value < 0.05 was statistically significant factors of diabetes foot deformity. RESULT The overall prevalence of foot deformity was 33.4% [95% CI: 28.9-38.3]. In the final logistic regression analysis, rural residency [AOR = 2.64, 95% CI: 1.31, 5.31], poor glycemic control [AOR = 2.41; 95% CI: 1.34, 4.33], diabetes duration ≥ 10 years [AOR = 2.74; 95% CI: 1.50, 5.02], inadequate footwear [AOR = 2.11; 95% CI: 1.17, 3.82] and presence of peripheral neuropathy [AOR = 8.21; 95% CI: 4.54, 14.84] were statistically significant associated factors with diabetes foot deformity. CONCLUSION The prevalence of foot deformity among adult diabetic patients was high. It is recommended to incorporate foot deformity screening in routine diabetic patient follow-ups especially for those with poor glycaemic control, rural residency, long diabetes duration, inadequate footwear, and diabetic peripheral neuropathy.

Abstract
PURPOSE Complex rigid foot deformities include three-plane deformities and usually presents with poor soft tissue coverage. In the last decades, gradual correction with computer-assisted fixator became an appropriate option for the treatment rigid foot deformities. This study aims to report our experience about treatment of complex foot deformities using Smart Correction fixator system®. METHODS We retrospectively analyzed 13 complex rigid foot deformities of ten consecutive patients treated with Smart Correction fixator system® from 2016 to 2020. Primary outcomes were classified as good, fair, and poor according to previously determined criteria. The outcomes were also assessed with The Manchester-Oxford Foot Questionnaire (MOXFQ). Non-parametric analysis (Wilcoxon test) for continuous variables and the Fisher's exact test for categorical variables were used. RESULTS Plantigrade foot was achieved in all patients after correction program. Supramalleolar osteotomy was applied in nine feet, midfoot osteotomy was applied in two feet, hindfoot osteotomy was required in one foot, and only soft tissue distraction performed in two feet. Two patients had recurrent deformity managed by further acute corrections. The mean MOXFQ scores improved from 72.7 preoperatively to 24.8 at last follow-up. CONCLUSIONS Present study shows that SCF the reliable option for the treatment of complex foot deformities, which also facilitates three-plane correction and concomitant lengthening with gradual soft tissue balance.

Quantitative assessment of plantar pressure patterns in relation to foot deformities in people with hereditary motor and sensory neuropathies. J Neuroeng Rehabil 2023; 20:65. [PMID: 37194095 DOI: 10.1186/s12984-023-01172-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2022] [Accepted: 03/30/2023] [Indexed: 05/18/2023] Open
Abstract
BACKGROUND Hereditary motor and sensory neuropathies (HMSN), also known as Charcot-Marie-Tooth disease, are characterized by affected peripheral nerves. This often results in foot deformities that can be classified into four categories: (1) plantar flexed first metatarsal, neutral hindfoot, (2) plantar flexed first metatarsal, correctable hindfoot varus, (3) plantar flexed first metatarsal, uncorrectable hindfoot varus, and (4) hindfoot valgus. To improve management and for the evaluation of surgical interventions, a quantitative evaluation of foot function is required. The first aim of this study was to provide insight into plantar pressure of people with HMSN in relation to foot deformities. The second aim was to propose a quantitative outcome measure for the evaluation of surgical interventions based on plantar pressure. METHODS In this historic cohort study, plantar pressure measurements of 52 people with HMSN and 586 healthy controls were evaluated. In addition to the evaluation of complete plantar pressure patterns, root mean square deviations (RMSD) of plantar pressure patterns from the mean plantar pressure pattern of healthy controls were calculated as a measure of abnormality. Furthermore, center of pressure trajectories were calculated to investigate temporal characteristics. Additionally, plantar pressure ratios of the lateral foot, toes, first metatarsal head, second/third metatarsal heads, fifth metatarsal head, and midfoot were calculated to measure overloading of foot areas. RESULTS Larger RMSD values were found for all foot deformity categories compared to healthy controls (p < 0.001). Evaluation of the complete plantar pressure patterns revealed differences in plantar pressure between people with HMSN and healthy controls underneath the rearfoot, lateral foot, and second/third metatarsal heads. Center of pressure trajectories differed between people with HMSN and healthy controls in the medio-lateral and anterior-posterior direction. The plantar pressure ratios, and especially the fifth metatarsal head pressure ratio, differed between healthy controls and people with HMSN (p < 0.05) and between the four foot deformity categories (p < 0.05). CONCLUSIONS Spatially and temporally distinct plantar pressure patterns were found for the four foot deformity categories in people with HMSN. We suggest to consider the RMSD in combination with the fifth metatarsal head pressure ratio as outcome measures for the evaluation of surgical interventions in people with HMSN.

Clubfoot and its implications for the locomotion of a medieval skeleton from Estremoz, Portugal. INTERNATIONAL JOURNAL OF PALEOPATHOLOGY 2022; 38:13-17. [PMID: 35700547 DOI: 10.1016/j.ijpp.2022.05.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/20/2022] [Revised: 05/17/2022] [Accepted: 05/23/2022] [Indexed: 06/15/2023]
Abstract
OBJECTIVE This study describes foot bone anomalies and the degenerative changes associated with locomotion adaptations. MATERIALS An adult male (approximately 29-46 years old) from Estremoz, Portugal (13th-15th century). METHODS The skeletal anomalies observed in this skeleton were described and measurements were compared between both sides of the individual and with the mean of the adult males from the same collection. RESULTS The most anomalous bones are the right medial cuneiform and metatarsals. Degenerative changes are more severe on the left lower limb and right upper limb. CONCLUSIONS This skeleton represents a unilateral case of talipes varus of the right foot, with the metatarsals being more affected while previously published cases show more severe anomalies of the hindfoot. The degenerative changes observed in the skeleton suggest that both legs and arms, aided by crutches, were used for locomotion. SIGNIFICANCE This case shows that club foot skeletal anomalies are variable and the pattern of bony changes throughout the body can reveal locomotion adaptations. LIMITATIONS The possibility of a genetic cause cannot be assessed due to the absence of paleogenomic data. SUGGESTIONS FOR FURTHER RESEARCH Since the anomalies found in this case are different than those previously published, we recommend care when analysing foot bones.

Abstract
BACKGROUND This study compares outcomes of patients with severe, multiplanar, fixed, pantalar deformities undergoing limb preservation with either pantalar fusion (PTF) or talectomy and tibiocalcaneal fusion (TCF), versus below knee amputation (BKA). METHODS Fifty-one patients undergoing either PTF, TCF and BKA for failed management of severe pantalar deformity were evaluated retrospectively. Twenty-seven patients underwent PTF, 8 TCF and 16 BKA. Median age at surgery was 55.0 years (17-72 years) and median follow-up duration was 49.9 months (24.0-253.7 months). Clinical evaluation was undertaken using the MOxFQ, EQ-5D and Special Interest Group in Amputee Medicine score (SIGAM). Patients were also asked whether they were satisfied with their surgery and whether they would have the same surgery again. RESULTS There was no statistically significant difference in functional outcomes, satisfaction, or complications between the groups. Twenty-two patients undergoing PTF (81.5%), 6 patients undergoing TCF (75%), and 15 patients undergoing BKA (93.8%) were satisfied overall (p = 0.414). There was no difference in the proportion of patients who would opt for the same procedure again (p = 0.142): 23 in the PTF group (85.2%), 8 in the TCF group (100%), and 11 in the BKA group (68.8%). Seven patients undergoing PTF (25.9%), 2 patients undergoing TCF (25%) and 6 patients undergoing BKA (37.5%) had major complications (p = 0.692). CONCLUSION This study concludes that PTF, TCF and BKA can all provide an acceptable outcome in treatment of severe, degenerative pantalar deformities. This data may be useful in counselling patients when considering salvage versus amputation in such cases. LEVEL OF EVIDENCE Level 3(Original) Clinical Research Article.

Abstract
BACKGROUND The purpose of this study was to clarify the incidence rate and the risk factors for the progression of the hallux valgus deformity. METHODS Patients who had weight-bearing radiographs of the foot taken twice or more, with a ≥2-year interval, were retrospectively analyzed. Progression of the deformity was defined as an increase in the hallux valgus angle of ≥5° during the follow-up. The association of hallux valgus progression with patient characteristics and radiographic measurements at baseline was determined using univariate and multivariate analyses. RESULTS Totally, 268 patients (217 women and 51 men; median age, 64 years) were analyzed. An increase in the hallux valgus angle of ≥5° occurred in 44 (17%) patients in a median follow-up of 49 months. Large hallux valgus angle (odds ratio, 1.07) on the dorsoplantar radiograph at baseline were independent risk factors for the progression of the deformity. CONCLUSION Progression of the hallux valgus deformity occurred in one of six patients. Furthermore, large hallux valgus angle was the risk factor for subsequent deformity progression. Patients with large hallux valgus angle should be informed about the possible progression of the deformity.

Abstract
BACKGROUND The dynamic plantar pressure patterns of children and adolescents with Charcot-Marie-Tooth (CMT) disease and its relationship to musculoskeletal alterations may help to understand the natural history of the disease and improve therapeutic interventions. RESEARCH QUESTION The study compared dynamic plantar pressure patterns in children and adolescents with and without CMT. It also tested the associations between isometric muscle strength (IMS), passive range of motion (ROM), foot posture and dynamic plantar pressure patterns in CMT. METHODS This cross-sectional study compared children and adolescents (aged 8-18 years) with CMT (n = 40) with a typical group (n = 40). The plantar pressure distribution during gait was recorded, and the contact area (CA), peak pressure (PP), contact time (CT) and pressure-time integral (PTI) in five foot regions (rearfoot, midfoot lateral, midfoot medial, lateral forefoot and medial forefoot) were analysed. The IMS of the dorsiflexors and plantar flexors, passive ROM, and foot posture were also recorded. RESULTS PP (medial midfoot and medial forefoot) and PTI (rearfoot, lateral midfoot and medial forefoot) were higher in children with CMT compared with the typical group. The adolescents with CMT presented a less CA (whole foot) and a higher CT (medial midfoot) when compared with typical group. For CMT, in the medial midfoot, plantar flexor IMS associated with PP (β=-11.54, p = 0.01) and PTI (β=-3.38, p = 0.04); supinated foot posture associated with PP (β = 33.89, p = 0.03) and PTI (β = 12.01, p = 0.03). SIGNIFICANCE Children with CMT showed clear changes in most of the dynamic plantar pressure variables, while adolescents with CMT showed changes mostly in CA and CT. This information together with the associations established between supinated foot, dorsiflexion ROM and plantar flexions IMS can be useful for guiding rehabilitation professionals in their therapies.

Abstract
The cavovarus foot (CF) is a complex three-dimensional foot deformity. In addition to primary forms, secondary forms can be distinguished. The diagnosis of CF is made clinically; however, anamnestic information, a targeted examination including neurological status and at least radiological imaging using the hindfoot-centered imaging technique are required to determine the treatment. Conservative treatment for CF consists of the provision of insoles up to the adaptation of an orthopedic custom-made shoe, depending on the severity of the deformity. The indications for a surgical procedure are present in the case of increasing complaints, although the timing should be extensively discussed with the patient in order to be able to achieve the best functional results. Surgical treatment is generally complex but a combination of soft tissue interventions and osteotomy/arthrodesis can usually be used to achieve a plantigrade foot position and thereby enable the patient to walk with a functionally improved gait.

Is the Apert foot an overlooked aspect of this rare genetic disease? Clinical findings and treatment options for foot deformities in Apert syndrome. BMC Musculoskelet Disord 2020; 21:788.

Abstract
BACKGROUND Apert syndrome is characterised by the presence of craniosynostosis, midface retrusion and syndactyly of hands and feet, thus, synonymously referred to as acrocephalosyndactyly type I. Considering these multidisciplinary issues, frequently requiring surgical interventions at an early age, deformities of the feet have often been neglected and seem to be underestimated in the management of Apert syndrome. Typical Apert foot features range from complete fusion of the toes and a central nail mass to syndactyly of the second to fifth toe with a medially deviated great toe; however, no clear treatment algorithms were presented so far. This article reviews the current existing literature regarding the treatment approach of foot deformities in Apert syndrome. STATE-OF-THE-ART TOPIC REVIEW Overall, the main focus in the literature seems to be on the surgical approach to syndactyly separation of the toes and the management of the great toe deformity (hallux varus). Although the functional benefit of syndactyly separation in the foot has yet to be determined, some authors perform syndactyly separation usually in a staged procedure. Realignment of the great toe and first ray can be performed by multiple means including but not limited to second ray deletion, resection of the proximal phalanx delta bone on one side, corrective open wedge osteotomy, osteotomy of the osseous fusion between metatarsals I and II, and metatarsal I lengthening using gradual osteodistraction. Tarsal fusions and other anatomical variants may be present and have to be corrected on an individual basis. Shoe fitting problems are frequently mentioned as indication for surgery while insole support may be helpful to alleviate abnormal plantar pressures. CONCLUSION There is a particular need for multicenter studies to better elaborate surgical indications and treatment plans for this rare entity. Plantar pressure measurements using pedobarography should be enforced in order to document the biomechanical foot development and abnormalities during growth, and to help with indication setting. Treatment options may include conservative means (i.e. insoles, orthopedic shoes) or surgery to improve biomechanics and normalize plantar pressures. LEVEL OF EVIDENCE Level V.

Abstract
Aims To assess if congenital foot deformity is a risk factor for developmental dysplasia of the hip (DDH). Methods Between 1996 and 2012, 60,844 children were born in Sør-Trøndelag county in Norway. In this cohort study, children with risk factors for DDH were examined using ultrasound. The risk factors evaluated were clinical hip instability, breech delivery, a family history of DDH, a foot deformity, and some syndromes. As the aim of the study was to examine the risk for DDH and foot deformity in the general population, children with syndromes were excluded. The information has been prospectively registered and retrospectively analyzed. Results Overall, 494 children (0.8%) had DDH, and 1,132 (1.9%) a foot deformity. Of the children with a foot deformity, 49 (4.3%) also demonstrated DDH. There was a statistically significant increased association between DDH and foot deformity (p < 0.001). The risk of DDH was highest for talipes calcaneovalgus (6.1%) and club foot (3.5%), whereas metatarsus adductus (1.5%) had a marginal increased risk of DDH. Conclusion Compared with the general population, children with a congenital foot deformity had a significantly increased risk for DDH and therefore we regard foot deformity as a true risk factor for DDH.

Abstract
AIM The aim of the current study is to introduce a new therapeutic strategy for simultaneous correction of complex foot deformities (CFD) and the associated lower limb deformities (LLD) by using Ilizarov technique with osteotomy and soft tissue procedure and to report its early clinical results. METHODS A retrospective review of CFD associated with LLD simultaneous correction utilizing the Ilizarov procedure together with osteotomy and soft tissue balance from 2015 to 2019 was conducted. RESULTS Thirty-two patients were followed for an average of 42.8 months. The mean external fixation time (EFT) was 6.5 months. The mean healing index (HI) was 1.7 months/cm. At the time of fixator removal, plantigrade feet were achieved in all patient and lower limb deformities were corrected. No recurrence of the deformities occurred. The mean LLRS AIM score was improved from 7.5 to 0.3. At the final follow-up, the ASAMI-Paley score was graded as excellent in all limbs in the aspect of bone results, and functional results were defined as excellent in 29 (90.6%) limbs and good in 3 (9.4%) limbs. The mean modified Dimeglio score was significantly improved from 7.2 to 1.3. No deep infection of the osteotomy site or nonunion was noted in the current study. CONCLUSION The therapeutic strategy by using the Ilizarov procedure together with osteotomy and soft tissue balance is a safe and effective way to simultaneously correct CFD and LLD. LEVEL OF EVIDENCE Level IV, retrospective case series.

Gait changes in persons with diabetes: Early risk marker for diabetic foot ulcer. Foot Ankle Surg 2020; 26:163-168. [PMID: 30712991 DOI: 10.1016/j.fas.2019.01.005] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2018] [Revised: 12/06/2018] [Accepted: 01/14/2019] [Indexed: 02/04/2023]
Abstract
Background Increasing prevalence of diabetic foot ulcer (DFU) and subsequent foot amputation in persons with type 2 diabetic neuropathy is a well known fact. The present study was aimed to identify the initial risk marker for DFU. Methods Dynamic plantar pressure analysis was done for persons with type 2 diabetes mellitus (T2DM) without neuropathy (D), patients with diabetic neuropathy (DN) with normal foot profile and healthy persons with normal foot profile (C). Results The data showed a significant difference in dynamic peak plantar pressure between C and DN (P = 0.035) and no significant difference between D and DN (P = 0.997). The dynamic segmental peak plantar pressure results showed significant difference only in the medial heel region (P = 0.009) among the three groups. Conclusions Gait variations and restrictions in subtalar and first metatarsophalangeal joint are found in persons with diabetic neuropathy even before the onset of foot deformity.

Minimally invasive vs open distal metatarsal osteotomy for hallux valgus - A systematic review and meta-analysis. J Clin Orthop Trauma 2020; 11:348-356. [PMID: 32405192 PMCID: PMC7211908 DOI: 10.1016/j.jcot.2020.04.016] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2020] [Revised: 04/14/2020] [Accepted: 04/14/2020] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND Numerous publications of the late 20th century have presented the radiological outcome of open technique for distal metatarsal osteotomy for mild to moderate hallux valgus and the clinical outcomes by means of well-established scoring systems which have been published and make these open techniques today's benchmark and gold standard. Minimally invasive procedures reduce surgical trauma because they are performed without large incisions, and injury to the soft tissues is limited. This has the theoretical advantages of improved recovery and decreased rehabilitation times. There is however limited literature to prove the same for minimally invasive surgery for hallux valgus.Our aim was thus to pool all available comparative literature on minimally invasive hallux valgus surgery done for mild to moderate hallux valgus versus open surgical approaches. METHODS A PubMed, Embase and Scopus search was performed using the keywords ('hallux valgus' OR bunion) AND ('minimally invasive' OR percutaneous) AND osteotomy. A total of 473 records were identified and out of which nine studies were included in the final review. RESULTS Most available studies are either randomized control trials, or prospective cohort studies providing good level of evidence. Radiological analysis showed similar correction with both MIS and open osteotomies. In functional analysis results were different with open techniques providing better results in terms of AOFAS score. (p < 0.0001). VAS score and complication rate were similar in both groups. DISCUSSION/CONCLUSION We conclude that based on available literature MIS provides equivalent radiological outcomes with respect to open surgery but functionally despite the promising results (good to excellent in most series), the outcomes in terms of function are not as good as open surgery. MIS techniques provide satisfactory outcomes for mild-to-moderate severity of hallux valgus though not as good as open surgery. There is evolving literature for this relatively new procedure. Longer duration of follow up and bigger numbers would allow for more meaningful data analysis and conclusions to be drawn as more studies come forward.

Abstract
Metatarsus adductus (MA) is a congenital condition resulting in adduction of the forefoot at the tarsometatarsal joint, medial metatarsal deviation, supination of the hindfoot through the subtalar joint, and plantarflexed first ray. The exact underlying pathophysiology remains elusive. There is increasing evidence highlighting the importance of recognizing MA as an associated deformity that complicates management of hallux valgus (HV). Unfortunately, metatarsalgia and lesser toe pathology is also common in this population. We present a review regarding the epidemiology, pathomechanics, and a comprehensive surgical treatment algorithm to optimize the management of patients with MA, HV, lesser toe deformity, and metatarsalgia.

Abstract
BACKGROUND Clubfoot is a treatable abnormality that can be managed with early intervention. However, there is a lack of public knowledge regarding clubfoot, which can delay treatment. This study aimed to assess the public awareness of clubfoot and knowledge regarding the importance of treatment in early childhood. METHODS This cross-sectional survey spanned 6 months, from June through November 2018, and involved persons living in Saudi Arabia. To collect data on public awareness of clubfoot risk factors, treatment, and prognosis, a questionnaire was developed by orthopedic experts and disseminated online. The target population included people of both genders and all age groups from the general population, regardless of their knowledge of someone with clubfoot. RESULTS By the end of the study period, 746 participants completed the online survey. In total, 520 of the respondents (69.7%) had never heard about clubfoot syndrome. Among the participants, 5.4% had a child with clubfoot syndrome and 4.6% were aware of clubfoot because they had an affected child. The top resource accessed by respondents for obtaining knowledge about clubfoot was social media channels (38.4%), followed by obtaining knowledge from relatives and friends (19.9%). The most reported perceived cause of clubfoot was hereditary and genetic disorders (58.4%), followed by neurological disorders (39.9%). CONCLUSIONS Results show that there is low public knowledge of clubfoot which may be attributed to a lack of awareness campaigns. We recommend increasing awareness regarding clubfoot through social media platforms and public campaigns in key locations, such as malls, as this may encourage people to seek early treatment. This is important because early management of clubfoot is less invasive and with regular follow-up, leads to better patient outcomes.

Abstract
BACKGROUND Charcot neuropathic osteoarthropathy (CNO) is one of the most devastating complications of neuropathy in patients with diabetes. Establishing diagnosis of CNO is difficult, due to the lack of clear clinical and radiological diagnostic criteria. Diagnosis is even more difficult when there is atypical and bilateral clinical presentation. Since CNO may lead to foot deformity, lower-extremity amputation and significant decrements in quality of life, it must be detected and treated without delay. Treatment focuses mainly on interruption of the inflammatory process and relief from pain using feet offloading devices. In more severe cases, surgical intervention may be needed. Additionally, the use of custom-made insoles and custom-made orthopaedic shoes is mandatory. CASE PRESENTATION We report a case of a young diabetic patient who presented to our clinic with bilateral and atypical presentation of Charcot foot disease. Patient was treated successfully upon diagnosis with bilateral aircast offloading. Unfortunately, due to depression and non-compliance, the disease progressed to severe and permanent lesions later on. CONCLUSION Despite the rareness of this disease, clinicians must include CNO into differential diagnosis of diabetic foot oedema, inflammation and deformity.

Abstract
Introduction Tibialis anterior tendon (TAT) rupture and cuboid-navicular coalition (CNC) are rare, to the best of our knowledge, only 238 cases of TAT rupture and 34 cases of CNC are described in the past century. Case Report A 47-year-old man came with a sudden onset of foot pain including drop foot to our department. We diagnosed a TAT rupture, which was fixed through suture. The pathologist testified degenerative changes in the tendon. In addition, a CNC was diagnosed. No extra treatment was necessary for the CNC. At the 6-year follow-up examination, the patient had no pain and went back to normal day activities (AOFAS 95/100 points). Conclusion We presume that, in our case, the long-term stress at the TAT through the foot deformity, caused by the CNC, may have supported the tendon rupture. CNC normally is symptom free. Therapy of a painful CNC should start with a conservative therapy. When this fails, an operation can be considered.

Abstract
The burden of peripheral artery disease (PAD) and diabetes in Asia is projected to increase. Asia also has the highest incidence and prevalence of end-stage renal disease (ESRD) in the world. Therefore, most Asian patients with PAD might have diabetic PAD or ESRD-related PAD. Given these pandemic conditions, critical limb ischemia (CLI) with diabetes or ESRD, the most advanced and challenging subset of PAD, is an emerging public health issue in Asian countries. Given that diabetic and ESRD-related CLI have complex pathophysiology that involve arterial insufficiency, bacterial infection, neuropathy, and foot deformity, a coordinated approach that involves endovascular therapy and wound care is vital. Recently, there is increasing interaction among cardiologists, vascular surgeons, radiologists, orthopedic surgeons, and plastic surgeons beyond specialty and country boundaries in Asia. This article is intended to share practical Asian multidisciplinary consensus statement on the collaboration between endovascular therapy and wound care for CLI.

Abstract
BACKGROUND With aging, the feet of the elderly above 60 years old in China present degenerative changes, deformities, and diseases, which significantly affect their daily activities. OBJECTIVES The authors aimed to study the morphological characteristics of the feet and identify the foot type according to size (length and width) and defect characteristics of elderly feet in China. METHODS A convenient sample of 1000 subjects above 60 years old was recruited mainly in the regions of Shanghai, Shaanxi, Henan, Hebei, and Sichuan in China. Foot images were collected, and 800 (male 398, female 402) valid questionnaires were recovered. A total of 800 elderly subjects as the test group were invited to measure their foot sizes by means of a Footprint Collector (Tong Yuan Tang Health Management Limited, Qingdao in Shandong province). The foot type of the elderly was compared with that of the general adult Chinese population as the control group using the t-test for independent samples. RESULTS Hallux valgus (46.9%) and flat foot (50.0%) were the most common foot shape deformities. The most frequent foot diseases were foot scaling (91.2%) and calluses (96.3%). The medial width of the first metatarsal-toe joint of the elderly was significantly higher (elderly female, 44.95±4.86mm; elderly male, 48.55±4.94mm) than that of the general adult population (adult female, 40.18±3.43mm; adult male, 43.22±3.20mm) (p<0.01). CONCLUSION The foot length of the elderly was not significantly different from that of the general adult Chinese population. The width of the first metatarsal-toe joint in the forefoot of the elderly was significantly higher than that of the general adult Chinese population, which was consistent with the result that a high proportion of elderly subjects presented hallux valgus.

Abstract
Triple (talonavicular, subtalar, and calcaneocuboid) joint arthrodesis and most recently double (talonavicular and subtalar) joint arthrodesis have been well proposed in the literature for surgical repair of the elective, posttraumatic, and/or neuropathic hindfoot deformities. The articulation of the hindfoot with the ankle and midfoot is multiaxial, and arthrodesis of these joints can significantly alter the lower extremity biomechanical manifestations by providing anatomic correction and alignment. This article reviews the indications and preoperative planning for some of the most common procedures to address the hindfoot deformity.

Abstract
AIMS To determine local and systemic markers of inflammation and bone mineral density (BMD) in the foot and central sites in participants with diabetes mellitus and peripheral neuropathy (DMPN) with and without acute Charcot neuropathic osteoarthropathy (CN). METHODS Eighteen participants with DMPN and CN and 19 participants without CN had foot temperature assessments, serum markers of inflammation [C-reactive protein, (CRP) and erythrocyte sedimentation rate, (ESR)] and BMD of the foot, hip and lumbar spine at baseline and 1year follow-up. RESULTS CN foot temperature difference was higher compared to DMPN controls at baseline (4.2±1.9°F vs. 1.2±0.9°F, P<0.01) and after 1year (2.9±3.2°F vs. 0.9±1.1°F, P<0.01). Serum inflammatory markers in the CN group were greater at baseline and remained elevated 1year later compared to DMPN controls (CRP, P=0.02, ESR, P=0.03). All pedal bones' BMD decreased an average of 3% in the CN foot with no changes in hip or lumbar spine. DMPN controls' foot, hip and lumbar spine BMD remained unchanged. CONCLUSIONS Local and systemic inflammation persists 1 year after CN with an accompanying pedal osteolysis that may contribute to mid foot deformity which is the hallmark of the chronic Charcot foot.

Abstract
BACKGROUND Transverse-plane foot deformities are a frequently encountered issue in children with neurological disorders. They are the source of many symptoms, such as pain and walking difficulties, making their prevention very important. OBJECTIVES We aim to describe the use and tolerability of a side pole static ankle foot orthosis used to prevent transverse-plane foot deformities in children with neurologic disorders. STUDY DESIGN Monocentric, retrospective, observational study. METHODS Medical data were collected from 103 children with transverse-plane foot deformities in one or both feet caused by a neurological impairment. All children were braced between 2001 and 2010. RESULTS Unilateral orthosis was prescribed for 32 children and bilateral orthosis for 71. Transverse-plane foot deformities were varus in 66% of the cases and an equinus was associated in 59.2% of the cases. Mean age for the first prescription was 8.6 years. For the 23 patients present at the 4-year visit, 84.8% still wore the orthosis daily, and 64.7% wore the orthosis more than 6 h per day. The rate of permanent discontinuation of wearing the orthosis was 14.7%. CONCLUSION The side pole static ankle foot orthosis is well tolerated with very few side effects, which promotes regular wearing and observance. Clinical relevance Side pole static ankle foot orthoses are well tolerated and can be safely used for children with foot abnormalities in the frontal plane that have a neurological pathology origin.

Abstract
The purpose of this study is to analyse and compare the impact of hallux valgus (HV) in a sample of adult women with varying degrees of HV scores obtained with regard to foot health and health in general. A total 100 female patients of mean age 43·04 ± 16·84 years who attended a podiatric clinic were asked to answer a questionnaire. The degree of deformity, HV, was determined on both feet of the patients using the Manchester Scale tool and the scores from the Foot Health Status Questionnaire were compared. Participants with varying degrees of HV recorded lower scores in Section 1 for the footwear and general foot health and higher scores for foot pain and foot function. In Section 2, they obtained lower scores in physical activity and social capacity and higher scores in vigour and general health. Differences between the four groups were evaluated by means of a t-test for independent samples, showing statistical significance (P < 0·001). This study has detected measurable differences of association between varying degrees of HV with impaired quality of life related to foot health in women.

Abstract
The use of inserts and orthopedic shoe adjustment represents an essential component of the conservative therapy of degenerative diseases and deformities of the musculoskeletal system. Inserts can have supportive, bedding and corrective effects and are used in particular for complaints of the feet and ankles. The combination of diverse materials allows a high level of cushioning and supporting features and corresponding longevity to be accomplished. The production is carried out on an individual basis and if necessary computer-assisted in order to achieve an optimal fit. For severe and rigid deformities the formation of pressure ulcers can be prevented by orthopedic shoe adjustment and by the use of orthopedic tailor-made shoes.

Abstract
[Purpose] The aim of this study was to evaluate the structural deformity of the foot
joint on the affected side in hemiplegic patients to examine factors that affect this kind
of structural deformity. [Subjects and Methods] Thirty-one hemiplegic patients and 32
normal adults participated. The foot posture index (FPI) was used to examine the shape of
the foot, the modified Ashworth scale test was used to examine the degree of ankle joint
rigidity, the navicular drop test was used to investigate the degree of navicular change,
and the resting calcaneal stance position test was used to identify location change of the
heel bone. [Results] The FPIs of the paretic side of the hemiplegic patients, the
non-paretic side of the hemiplegic patients, and normal participants were −0.25 ± 2.1,
1.74 ± 2.3, and 2.12 ± 3.4 respectively. [Conclusion] Our findings indicated that in
stroke-related hemiplegic patients, the more severe the spasticity, the more supinated the
foot. Further, the smaller the degree of change in the navicular height of hemiplegic
patients is, the more supinated the paretic side foot is. Additionally, a greater change
in the location of the calcaneus was associated with greater supination of the overall
foot.

Abstract
Concomitant hindfoot and midfoot deformity is common. Hindfoot fusion is associated with prolonged recovery and significant disability. Further surgery is often required to obtain a plantigrade foot. Understanding normal structural and kinematic relationships between the midfoot and hindfoot, as well as recognizing common combined patterns of midfoot and hindfoot deformity, can minimize the unanticipated consequences of hindfoot fusion. Treatment of residual or resultant midfoot deformity requires a thorough analysis of the deformity and familiarity with a variety of operative techniques for correction.

Abstract
BACKGROUND Rheumatoid arthritis results in postural instability, pain and functional limitations. As rheumatoid arthritis progresses, localised forefoot deformities such as hallux valgus and clawing of the lesser toes occur, leading to a high proportion of people with rheumatoid arthritis wearing sandals. Sandals may affect postural stability due to poor motion control. The aim was to assess two different open-toe sandals on postural stability in people with rheumatoid arthritis. METHODS Twenty women with rheumatoid arthritis were assessed in quiet standing under four conditions: (1) open-back sandal; (2) closed-back sandal; (3) own footwear and (4) bare feet. Postural stability was assessed as postural sway in the anterior-posterior and medial-lateral directions, with eyes open and eyes closed, using a pressure mat. Repeated measures analysis of variance tested the interaction effect of the footwear and eye conditions on anterior-posterior and medial-lateral sway. FINDINGS In eyes-open, there was no significant difference in anterior-posterior sway (P=.169) and medial-lateral sway (P=.325) for footwear conditions. In eyes-closed testing, compared with barefoot conditions, increased anterior-posterior sway was observed with participants' footwear (P<.0001), the open-back sandal (P=.005), and the closed-back sandal (P=.017). With eyes closed, increased anterior-posterior sway was also observed with the participants' footwear compared with the closed-back sandal (P=.041). Increased medial-lateral sway was observed with the closed-back sandal compared with bare feet (P=.014). INTERPRETATION Sandals may be detrimental to older women with well-established rheumatoid arthritis when eyes are closed. Further investigation is needed to evaluate the effect of sandals on dynamic tasks.

Abstract
Cavovarus is a deformity commonly associated with a variety of underlying disorders, and treatment of severe cavovarus foot with an underlying progressive disorder is very challenging. Often patients have undergone some prior surgery at least once, with increased potential risk of neurovascular injury and breakdown of soft tissue. In addition, concomitant problems such as torsional malalignment and leg-length discrepancy should also be addressed to prevent recurrence and treatment failure. In this article, indications and an algorithmic approach with various osteotomies for the treatment of cavovarus deformity using external fixation are discussed in detail.

Abstract
BACKGROUND Metatarsophalangeal joint deformity is associated with skin breakdown and amputation. The aims of this study were to compare intrinsic foot muscle deterioration ratios (ratio of adipose to muscle volume), and physical performance in subjects with diabetic neuropathy to controls, and determine their associations with 1) metatarsophalangeal joint angle and 2) history of foot ulcer. METHODS 23 diabetic, neuropathic subjects [59 (SD 10) years] and 12 age-matched controls [57 (SD 14) years] were studied. Radiographs and MRI were used to measure metatarsophalangeal joint angle and intrinsic foot muscle deterioration through tissue segmentation by image signal intensity. The Foot and Ankle Ability Measure evaluated physical performance. FINDINGS The diabetic, neuropathic group had a higher muscle deterioration ratio [1.6 (SD 1.2) vs. 0.3 (SD 0.2), P<0.001], and lower Foot and Ankle Ability Measure scores [65.1 (SD 24.4) vs. 98.3 (SD 3.3) %, P<0.01]. The correlation between muscle deterioration ratio and metatarsophalangeal joint angle was r=-0.51 (P=0.01) for all diabetic, neuropathic subjects, but increased to r=-0.81 (P<0.01) when only subjects with muscle deterioration ratios >1.0 were included. Muscle deterioration ratios in individuals with diabetic neuropathy were higher for those with a history of ulcers. INTERPRETATION Individuals with diabetic neuropathy had increased intrinsic foot muscle deterioration, which was associated with second metatarsophalangeal joint angle and history of ulceration. Additional research is required to understand how foot muscle deterioration interacts with other impairments leading to forefoot deformity and skin breakdown.

Abstract
Both congenital and acquired orthopaedic deformities are common in patients with spina bifida. Examples of congenital deformities, which are present at birth, include clubfoot and vertical talus. Acquired developmental deformities are related to the level of neurologic involvement and include calcaneus and cavovarus. Orthopaedic deformities may also result from postoperative tethered cord syndrome. The previously published Part I reviewed the overall orthopaedic care of a patient with spina bifida, with a focused review of hip, knee, and rotational deformities. This paper will cover foot and ankle deformities associated with spina bifida, including clubfoot, equinus, vertical talus, calcaneus and calcaneovalgus, ankle and hindfoot valgus, and cavovarus. In addition, this paper will address the issues surrounding skin breakdown in patients with spina bifida.
