Transfer of Second Toe for the Treatment of Traumatic Thumb Amputation in a Four-year-old Child: A Case Report.

Microsurgical toe transfer for thumb reconstruction is a challenging procedure, considering the technical skills necessary to perform it, as well as the difficult postoperative evaluation of esthetical and functional aspects. The present is the report of the case of a 3-year-old child who suffered a traumatic thumb amputation. Thumb reconstruction was performed through microsurgical toe transfer months after replantation failure. Subjective and objective outcome assessments were performed five years after the procedure. The functional outcome was evaluated through the Childhood Health Assessment Questionnaire (CHAQ) and the Jebsen-Taylor Hand Function Test (JTHFT). The Jamar dynamometer (Sammons Preston, Bolingbrook, IL, US) and the Jamar Pinch Gauge (Sammons Preston) devices were used to assess the handgrip and pinch strength respectively. The Semmes-Weinstein monofilament and two-point discrimination tests were performed. The patient presented an excellent functional outcome, partial recovery of strength, complete sensory recovery, and minimal donor site morbidity. A radiographic evaluation was also performed, and it demonstrated the preservation of the epiphyseal plate and the growth potential of the transplanted toe. In all aspects, the data observed reinforce the benefits and indications of toe transfer for thumb reconstruction in children.

Differences in the Size of Individual Plantar Intrinsic Foot Muscles Between Ballet Dancers and Non-Dancers.

INTRODUCTION: In classic ballet, choreography often involves tiptoe standing. Tiptoe standing requires a high and stable foot arch structure, which is achieved by contraction of the plantar intrinsic foot muscles (PIFMs). Long-term repetitive loading with a specific movement can induce hypertrophic adaptation of the associated muscles. For dancers, however, limited information on the size of individual PIFMs is available from previous studies. The purpose of this study was to determine the differences in the sizes of 10 individual PIFMs between dancers and non-dancers. METHODS: Muscle volumes (MVs) of 10 individual PIFMs were measured using magnetic resonance imaging in 15 female dancers and 15 female non-dancers. Muscles analyzed included abductor hallucis, flexor digitorum brevis, abductor digiti minimi, quadratus plantae, lumbricals, flexor hallucis brevis, adductor hallucis oblique head, adductor hallucis transverse head, flexor digiti minimi, plantar/dorsal interossei. In addition to absolute MVs, relative MVs normalized to body mass (rMVBM) and the percentage of individual MVs relative to the sum of 10 individual PIFM MVs (%MVWHOLE) were calculated. RESULTS: The absolute MVs of 6 individual PIFMs, including the flexor digitorum brevis and lumbricals, were +16% to 59% larger in dancers than in non-dancers (P ≤ .048). The rMVBM of all individual PIFMs were +35% to 95% larger in dancers than in non-dancers (P ≤ .019). The %MVWHOLE of the flexor digitorum brevis and lumbricals were +10% to 36% higher (P ≤ .014) and those of the abductor digiti minimi and adductor hallucis oblique head were +8% to 11% lower (P ≤ .037) in dancers than in non-dancers. CONCLUSIONS: For all 3 MV measures, only the flexor digitorum brevis and lumbricals, which are functionally specialized for flexion of the second to fifth metatarsophalangeal joints, were consistently larger in dancers than in non-dancers. This may be due to long-term repetitive loading on these PIFMs during ballet training involving tiptoe standing.

Diagnosis and management of COVID toes in outpatients: a case report.

BACKGROUND: Since the beginning of the coronavirus disease 2019 pandemic, the most common skin lesions observed due to infection with the severe acute respiratory syndrome coronavirus 2 are pseudochilblains (or coronavirus disease toes). However, this pathology remains infrequent and difficult to diagnose, as no specific test exists. CASE PRESENTATION: Two Caucasian women, 30 and 22 years old, presented to our General Medicine Unit with perniosis lesions on the feet during the first two waves of the coronavirus disease 2019 pandemic. They did not have respiratory or general symptoms of severe acute respiratory syndrome coronavirus 2 infection, the reverse transcription polymerase chain reaction on nasopharyngeal swabs was negative, and the serology was positive only in the first case. The clinical presentation differed for the two cases, as the second patient suffered from swelling and burning after cold application. The diagnosis was based on clinical presentation, temporality, exclusion of other differential diagnoses, and blood test results (positive serology in the first case and high level of CXCL13 and VEGF in the second), supported by current literature. Lesions resolved spontaneously in the first patient. The second case was hospitalized for pain management and received corticosteroid therapy with resolution of the symptoms. CONCLUSION: These two cases with different clinical presentations illustrate the diagnostic approach to coronavirus disease 2019, a challenging disease with diverse manifestations, including, in some cases, coronavirus disease toes. We present a literature review that illustrates the progression of scientific research. Skin lesions associated with coronavirus disease 2019 infection could be the expression of an important interferon type 1 response and should be considered in the differential diagnosis in a primary care setting.

Reconstructive Limb Salvage After COVID-19-Induced Gangrene and Amputation.

This case series describes the clinical course and reconstructive methods utilized for patients with diabetes and significant gangrene and necrosis following coronavirus disease 2019 (COVID-19) infection. COVID-19 produces mainly respiratory symptoms but has a variety of atypical presentations and sequelae. Serious complications are increased in patients with underlying medical conditions such as diabetes mellitus. By generating a prothrombotic milieu, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) increases the risk for arterial and venous thromboses. Inflammatory damage and micro-thromboses are thought to contribute to acro-ischemia, colloquially known as 'COVID toes,' which presents cutaneously as chilblain-like lesions. Necrosis can be severe and devastating, often resulting in major amputation. Two exemplary case reports are presented herein: first, a 57-year-old female presented for vascular evaluation with pedal gangrene to the midfoot one month after developing painful discoloration in her right toe. After angioplasty restored pedal blood flow, she received a transmetatarsal amputation (TMA) with a local tissue flap. Second, a 41-year-old female presented for vascular evaluation with extensive pedal gangrene three months after hospitalization for COVID-19. After arteriotomy improved pedal blood flow, she underwent a Lisfranc amputation followed by superficial circumflex iliac artery perforator (SCIP) flap reconstruction. Sufficient evidence suggests that COVID-19 impairs microcirculatory function and can be especially detrimental in diabetic patients. Reconstructive techniques in patients with severe gangrene with COVID toes help patients regain functionality.

Natural Treatment Options for Nail Disorders.

The growing demand for natural treatments has raised concerns among clinicians due to limited scientific evidence supporting their use. This review article addresses the issue by assisting dermatologists and general practitioners in recommending natural treatments for the following common nail disorders: nail brittleness, onychomycosis, periungual verrucae, paronychia, chloronychia, nail psoriasis, nail lichen planus, onychocryptosis, onycholysis, and congenital malalignment of the great toenail. One limitation is the scarcity of existing reviews on natural treatment options for nail disorders in the literature. Through a comprehensive review of existing literature, this article consolidates the available evidence on natural treatment options for these conditions. Although some natural treatments for nail disorders are supported by scientific evidence, the indiscriminate use of such remedies may lead to severe poisoning and health problems. Given the widespread and increasing use of natural treatments, clinicians play a pivotal role in educating patients about evidence-based remedies and debunking misleading claims. By doing so, clinicians can enhance patient safety and improve treatment outcomes. It is essential for healthcare professionals to be well-informed and equipped with the knowledge to differentiate between effective natural treatments and unverified claims, ensuring that patients receive appropriate care.

Prolonged Union in Conservative Treatment of Symphalangeal Toe Fractures: Case Series.

Background: Toe symphalangism is characterized by a fusion of the interphalangeal joint between the middle and distal phalanges. While typical lesser toe fractures heal well with conservative treatment, in our clinical experience, we encountered patients with symphalangeal toe fractures who experienced long-lasting pain and delayed radiographic union. Therefore, this study aimed to report radiographic outcomes following conservative treatment of symphalangeal fractures of the lesser toes. Methods: We retrospectively reviewed 14 patients with symphalangeal lesser toe fractures who were treated conservatively. We investigated the mechanism of injury and measured the time from the initial injury date to the complete radiographic union. The fracture gap distance was measured on an initial lateral radiograph. Results: Symphalangeal fractures involved the fourth toe in 4 patients (28.5%) and the fifth toe in 10 patients (71.4%). Regarding the mechanism of injury, 6 patients (42.9%) were injured by stubbing or bumping into the door, 5 patients (35.7%) were injured by tripping, 2 patients (14.3%) were injured by heavy objects falling directly on their toes, and 1 patient (2.3%) complained of pain after wearing pointed shoes for half a day. The mean time to complete union was 9.1 months, and the median period was 5.5 months (range, 0.8-29 months). The initial gap of the fracture was 0.60 mm (range, 0.30-1.04 mm). Conclusions: The results of our case series may help counsel patients in the outpatient clinic that prolonged healing time may be required for the union of symphalangeal toe fractures.

Experimental and Analytical Investigation of Self-Centering Precast Composite Walls with Sloped Plane Friction Dampers.

To reduce the damage to reinforced concrete shear walls in earthquakes and repair costs, a self-centering wall with sloped plane friction dampers (SPFDs) is proposed. In addition to the SPFDs, the proposed wall includes a precast composite wall, steel wall toes, and post-tensioned (PT) tendons. The steel wall toes embedded in the base of the precast wall were used to improve its strength, and the SPFDs installed in the steel toes were used to increase its energy dissipation capacity. To investigate the effect of the initial PT force and prestressing clamping force of the friction bolt on the seismic performance of the wall, quasistatic cyclic loading tests were carried out on three precast wall specimens. The damage to the self-centering walls was slight, the residual drift was small, and the energy dissipation met the specification requirements. The wall with the greater initial PT force showed higher self-centering and bearing capacity, and the wall with higher prestressing clamping forces showed greater energy dissipation capacity. Additionally, a calculation method for the bearing capacity of the precast wall, which was verified by comparison with the test results, is suggested.

Free vascularized fibula leads to hallux toe flexion deformity due to ischemic muscle contracture of flexor hallucis longus.

BACKGROUND: This study aimed to investigate the incidence of toe flexion deformity after fibular free flap transplantation and to analyze the etiology of the deformity. METHODS: Fifty patients underwent vascularized fibular free flap transplantation were retrospectively included. Statistical analysis examined correlations between deformity occurrence and resected fibula length and residual distal fibula length using the χ2 test. Doppler ultrasound and anatomical evaluations were conducted. RESULTS: Flexion deformity of the first toe was observed in all patients (100%), exacerbated by ankle dorsiflexion. χ2 test revealed no significant correlation between fibula length, distal residual fibula length, and flexion deformity. Doppler ultrasound revealed elevated echoes and blurred textures in the flexor hallucis longus post-fibular transplantation, while anatomical evaluation confirmed the peroneal artery as its primary nutrient supplier. CONCLUSION: This study reports a 100% incidence of toe flexion deformity post-transplantation. The deformity correlated strongly with ischemic contracture of the flexor hallucis longus.

No Efficacy with Noninvasive Brain Stimulation for Painful Legs and Moving Toes: A Case Report.

Introduction: Painful legs and moving toes (PLMT) is a rare neurological disorder characterized by neuropathic pain and involuntary movements in the lower limbs. The pathophysiological mechanisms are unclear, but central mechanisms might be involved, suggesting that noninvasive brain stimulation might be helpful. Thus far, no reports have been published on noninvasive brain stimulation to treat PLMT. Case Presentation: A 70-year-old female had a 1-year history of PLMT. After several unsuccessful medical attempts, the patient received repetitive transcranial magnetic stimulation and transcranial direct current stimulation to alleviate the pain and involuntary movements with no benefit. Conclusion: This is the first report on noninvasive brain stimulation in a PLMT patient. Although ineffective in our patient, noninvasive brain stimulation should be further studied in this often difficult to treat and debilitating syndrome.

A 23-year-old patient with bilateral hypoplastic thumbs and toes: A case report.

Key Clinical Message: However, it is noteworthy that certain patients with minor functional limitations in their hand may have experienced undiagnosed thumb hypoplasia during their childhood years. These individuals may have successfully adapted to their condition without seeking medical intervention and may express a preference for nonintervention (as in this case). Abstract: Thumb hypoplasia is a congenital underdevelopment of the thumb, accounting for 5%-15% of congenital hand disorders. It occurs equally among both genders and can affect both thumbs. The condition is categorized using Blauth's classification with Type I being the mildest form. We report a 23-year-old Syrian male presented with a bilateral restriction in opposition movement when using a pen or razor. Clinical examination and x-ray imaging revealed a bilateral Type I hypoplastic thumb with bilateral minimal hypoplasia of the toes. Despite the surgical treatment options available, the patient opted not to undergo surgery due to his adaptation to his condition. Hypoplastic thumb Type I is a congenital condition characterized by underdevelopment of the thumb. Bilateral thumb hypoplasia with toes hypoplasia is extremely rare. A full systemic evaluation should be done due to its associations with other syndromic manifestations and treatment options are discussed concerning the best functional outcomes and patient preferences.

Fibrodysplasia Ossificans Progressiva: A rare disease due to unawareness, case report and literature review.

INTRODUCTION AND IMPORTANCE: Fibrodysplasia Ossificans Progressiva is an ultra-rare genetic disorder of progressive soft tissue ossification. Due to unawareness and poor clinical suspicion, the rate of misdiagnosis, delay in diagnosis, and unnecessary diagnostic procedures leading to permanent injury and lifelong disability is common. Here we report this rare genetic disorder in a six years old child who was initially misdiagnosed as multiple exostoses and operated on. CASE PRESENTATION: A 6 year old child presented with swellings over the posterior neck and back for four years. The patient was misdiagnosed as a case of multiple exostoses and an excisional biopsy was done a year back. The swelling worsened after the excision; currently, she cannot move her neck from side to side, and flex and extend. Examination revealed multiple hard and slightly tender masses over the posterior neck, para scapular and thoracolumbar para spinal region. She also has hallux valgus deformity that had been present since birth. CT (computed tomography) scan confirmed extensive extra-skeletal soft tissue ossification. CLINICAL DISCUSSION: The progression of heterotopic ossification is characteristically anatomic and orderly, typically initially involving the body's dorsal, axial, cranial, and proximal regions and later in the ventral, appendicular, caudal, and distal regions. Skeletal muscles of the tongue, diaphragm, extra-ocular muscles, cardiac muscles, and smooth muscles are inexplicably spared. CONCLUSION: Early diagnosis prevents potentially harmful diagnostic and therapeutic procedures. The characteristic big toes malformation is the most important and best key for the early suspicion of the diagnosis.

Raynaud's phenomenon in the feet of Arctic open-pit miners.

The literature on Raynaud's phenomenon (RP) in the feet is scarce, especially in the occupational setting. The primary aim of our study was to investigate the occurrence of RP in the feet of miners. As part of the MineHealth project, written surveys and clinical examinations were completed by 260 Arctic open-pit miners working in northern Sweden and Norway (participation rate 53.6%). Data on RP were collected using standardised colour charts and questionnaire items. Clinical examination included assessing the perception of vibration and pain in both feet. There were eight women and three men who reported RP in the feet. Four also had RP in their hands but none acknowledged any first-degree relatives with the condition. Nine reported exposure to foot-transmitted vibration and one to hand-arm vibration. Seven showed signs of neurosensory injury in the feet. To conclude, the occurrence of RP in the feet of miners was 4.4%. Most cases with RP in the feet did not report the condition in the hands and were exposed to vibration transmitted directly to the feet. There were no reports of a hereditary component. Most cases with RP in the feet also had clinical findings suggestive of peripheral neuropathy in the feet.

A curious case of 'COVID toes' in pregnancy.

The novel coronavirus of 2019 (COVID-19) can affect multiple organ systems with a wide spectrum of illness severity. Its effect on the respiratory tract is well-documented and has resulted in considerable excess mortality worldwide. However, observed cutaneous manifestations of COVID-19 are rising, ranging from short-lived viral exanthems to vesicular eruptions and urticaria. An unusual subgroup of these manifestations - pseudo-chilblains, also referred to as pernio-like lesions or 'COVID toes' - describes the acral areas of erythema and oedema that can affect young individuals following COVID-19. We present a case associated with pustule and vesicle formation occurring in the context of pregnancy.

Are floating toes associated with lifestyle in children? A cross-sectional study.

BACKGROUND: Floating toes are a condition and deformity in which some of the toes are afloat. Many functional impairments in floating toes have been previously studied lately and several factors related to floating toes have also been reported. However, no reports have considered the relationship between lifestyle and floating toes among children. The purpose of this study was to reveal the prevalence of floating toes among school children and reveal its relationship with lifestyle. METHODS: In total, 138 young male baseball players were recruited. Lifestyle was evaluated by using a questionnaire and chosen whether the main lifestyle was Japanese or Western, if the bedding was futons or beds, and if the toilet was Japanese style (a squat toilet) or Western style. Floating toes were defined as toes that were not in contact with the mat. Ankle dorsiflexion in the knee-flexed and knee-extended positions was measured in a weight-bearing position. The relationship between the floating toes and lifestyles, and the comparison of ankle dorsiflexion range of motion between the lifestyles were statistically analyzed. RESULTS: Players living in a Western style showed a significantly higher prevalence of floating toes on both feet compared with the players living in a Japanese style (throwing side; 39% vs. 19%, p = 0.04, and non-throwing side; 43% vs. 19%, p = 0.01). Players living in a Western style with beds showed a significantly smaller range of motion on both sides of ankle dorsiflexion in the knee-flexed position compared with those who were not (throwing side; 37.2 ± 5.7° vs. 39.0 ± 6.6°, p = 0.04, and non-throwing side; 36.8 ± 5.8° vs. 38.6 ± 6.1°, p = 0.04). CONCLUSION: Children mainly living in a Western lifestyle showed a significantly higher prevalence of floating toes on both feet compared to those mainly living in a Japanese lifestyle. The prevalence of floating toes may be related to lifestyles among children. TRIAL REGISTRATION: The study was approved by the institutional review board of the Waseda University Graduate School of Sport Sciences (IRB number 2021-185).

The use of an Intra-medullary fusion system in hammer toe surgery; mid-term follow-up.

Objectives: To assess the efficacy of a new hammer-toe locking fusion system. METHODS: The retrospective study was conducted at Kutahya Evliya Çelebi Education and Research Hospital, and comprised data from March 2014 to January 2017 of patients of either gender with hammer toe deformity. The American Orthopaedic Foot and Ankle Society and visual analogue scale scoring systems were used. Radiological evaluation was also used to determine the lateral interphalangeal angle measurements. All patients were subjected to hammer toe surgery using new two-block interlocking fusion system, and were followed up for about 2 years. SPSS 25.0 for windows was used for analysis. RESULTS: According to gender, 13(65%) of patients were female and 7(35%) of patients were male. The overall mean age was 51.5±16.31 years (range: 20-72 years). Of all the surgeries, 9(45%) were performed on the right foot, and 11(55%) on the left foot. The follow-ups ranged 21-32 months. Compared to baselines values, American Orthopaedic Foot and Ankle Society scale and visual analogue scale scores significantly improved post intervention (p<0.05). CONCLUSIONS: Significantly favourable outcomes were noted, indicating the efficacy of the fusion process.

Cholesterol Embolization Syndrome Post Invasive Arterial Procedure: A Case Report.

Cholesterol embolization syndrome (CES) is a rare but systemic severe disease caused by the distal showering of cholesterol crystals after angiography, major surgery, thrombolysis, or anticoagulation. Here, we present a case of a 74-year-old male with a history of coronary artery disease, chronic kidney disease, peripheral vascular disease, antiphospholipid syndrome, and right internal carotid artery occlusion who developed purple discoloration and ulceration involving several toes two months after coronary artery bypass surgery. A broad differential diagnosis for blue toes was considered, and a biopsy was obtained, which revealed an arterial lumen filled with large cholesterol crystal spaces, confirming the diagnosis of CES. Treatment of CES remains a bimodal approach of supportive and prophylactic care. Although there is no direct evidence in favor of antiplatelet agents, their use seems reasonable because they have been shown to reduce the risk of other cardiovascular events in patients with extensive atherosclerosis. In this case, the patient's toe pain improved with the use of topical amitriptyline ketamine and has achieved complete resolution of pain and skin discoloration at a seven-month follow-up.

Immediate effect of the use of toe separators on dynamic balance and ankle range of motion: a pilot study.

BACKGROUND AND OBJECTIVES: Injuries involving ankle stability and range of motion are among the most frequent in athletes and in the general population. In response, this study aimed to assess the immediate effects of toe separators on dynamic stability and ankle range of motion in healthy young individuals. METHODS: Among the 68 eligible participants, 50 healthy and active subjects completed all trials. The impact of the intervention was evaluated using the Weight Bearing Lunge Test and Y-Test. The control condition performed the tests without toe separators, while the experimental condition performed the tests with toe separators. All participants performed both conditions with a wash-out period of at least 7 days between trials. RESULTS: Statistical analysis revealed no significant differences in dynamic balance (p > 0.05) and range of motion (p > 0.05) between the two conditions. Additionally, no asymmetries were detected between the lower limbs in both tests (p > 0.05). CONCLUSIONS: The results of this pilot study indicate that using toe separators does not have an immediate effect on ankle range of motion and dynamic balance in young, healthy individuals. Future research should consider evaluating intervention programs of longer duration and exploring different populations.

What are the key risk factors of keloid formation after repair of syndactyly of the toe?

PURPOSE: Keloid formation in toes area is rare. However, occurrence of this phenomenon in toes after the surgery of syndactyly repair has been reported. Risk factors of keloid formation in toes after syndactyly reconstructions are currently unknown. This study aimed to investigate the risk factors of keloid formation after the surgery of syndactyly repair of the toes. METHODS: We retrospectively reviewed our case series including patients who were treated surgically at our institution. We hypothesized some key factors of keloid formation and analyzed each of them statistically. RESULTS: A total of 105 patients were treated surgically at our hospital, and 9 patients were involved keloid formations after operations. Among our hypothesized key factors, the results of multivariate logistic regression analysis revealed the number of affected web spaces (OR 0.031; 95%CI 0.001-0.684; p = 0.028) was significantly different. Digital enlargement was not a significant factor (OR 17.731; 95%CI 0.686-458.174; p = 0.091). CONCLUSION: Involving multiple web space was associated with keloid formation after syndactyly release, on the other hand, toe enlargement did not show a significant difference. However, the digital enlargement showed high Odds ratio, we could not deny its high relativity for keloid formation. Further investigations are needed to clarify the key risk factors of keloid formation after the surgery of syndactyly repair of the toes.
