ABSTRACT

Abstract Objective To describe the profile of the patients and the results obtained with the use of an external fixator for metatarsal lengthening in brachymetatarsia. Methods A retrospective analysis of the medical records of patients with brachymetatarsia treated between January 2018 and April 2020 was performed. During this period, eight feet of six patients were operated on. Frequencies were estimated according to demographic and surgical aspects. Results All patients (100%; n= 6) were female, with a mean age of 28 years old, ranging from 15 to 48 years old, and were motivated to seek the orthopedic service due to aesthetic deformity. The deformity was bilateral in two patients and unilateral in four patients. The average lengthening time was 22 days ( ± 7.15, 95% confidence interval [CI]: 19.04-26.81). The lengthening speed was 0.5 mm/day, and the average total length of the lengthening was 11.46 mm ( ± 3.57; 95%CI: 9.52-13.40). Half of the patients (50%; n= 3) had local infection of the pins and were treated with antibiotics, and the others did not report any postsurgical complications. All patients denied pain or calluses after the surgical procedure and reported satisfaction with the results. Conclusion All patients were female and sought surgery for brachymetatarsia for aesthetic reasons. Osteogenic distraction at a rate of 0.5 mm/day resulted in successful lengthening of the metatarsal, with a low frequency of complications, good clinical outcomes, and high patient satisfaction.


Resumo Objetivo Descrever o perfil dos pacientes e os resultados obtidos com o uso de fixador externo para alongamento de metatarso em braquimetatarsia. Métodos Foi realizada uma análise retrospectiva dos prontuários de pacientes com braquimetatarsia tratados entre janeiro de 2018 e abril de 2020. Durante este período, foram operados oito pés de seis pacientes. Foram coletadas e estimadas as frequências em relação a aspectos demográficos e cirúrgicos. Resultados Todas as pacientes (100%; n= 6) eram do sexo feminino, com média de idade de 28 anos, variando de 15 a 48 anos, e motivadas a buscar o serviço de ortopedia em função da deformidade estética. O acometimento era bilateral em duas pacientes e unilateral em quatro pacientes. O tempo médio de alongamento foi de 22 dias ( ± 7,15; intervalo de confiança [IC] 95%: 19,04-26,81). A velocidade de alongamento foi de 0,5 mm/dia e o comprimento médio total do alongamento foi de 11,46 mm ( ± 3,57; IC95%: 9,52-13,40). Metade das pacientes (50%; n= 3) teve infecção local dos pinos e foi tratada com antibióticos; as demais não relataram nenhuma complicação pós-cirúrgica. As pacientes negaram dor ou calosidade após o procedimento cirúrgico e relataram satisfação com os resultados. Conclusão Todas as pacientes eram do sexo feminino e buscaram a cirurgia para braquimetatarsia por motivos estéticos. A distração osteogênica a uma taxa de 0,5 mm/dia resultou em alongamento bem-sucedido do metatarso, com uma baixa frequência de complicações, bons resultados clínicos e alta satisfação das pacientes.

ABSTRACT

Abstract Objective To present the clinical and radiographic results of hallux valgus surgical correction using four percutaneous techniques, chosen according to a predefined radiographic classification. Methods We prospectively evaluated 112 feet in 72 patients with hallux valgus operated over the course of 1 year. Percutaneous distal soft tissue release (DSTR) and the Akin procedure (DSTR-Akin) were performed in mild cases. In mild to moderate hallux valgus with distal metatarsal joint angle > 10°, we added the Reverdin-Isham (RI) osteotomy. In moderate cases with joint incongruity, we performed the percutaneous chevron (PCH). Finally, a Ludloff-like percutaneous proximal osteotomy fixed (PPOF) with a screw was proposed in severe cases with an intermetatarsal angle (IMA) > 17°. According to these criteria, 26 DSTRs-Akin, 36 PCHs, 35 RIs, and 15 PPOFs were performed. The mean follow-up was of 17.2 months (range: 12 to 36 months). The mean age at operation was 58.8 years (range: 17 to 83 years), and 89% of the patients were female. Results The mean preoperative hallux valgus angle (HVA) and the IMA decreased from 21° to 10.2° and from 11.2° to 10.3° respectively in the DSTR-Akin. In the RI, the mean HVA decreased from 26.6° to 13.7°, and the IMA, from 11.2° to 10.3°; in the PCH, the mean HVA decreased from 31° to 14.5°, and the IMA decreased 14.9° to 10.7°; as for the PPOF, the mean HVA decreased from 39.2° to 17.7°, and the IMA, from 11.8° to 6.8°. The average ankle and hindfoot score of the American Orthopaedic Foot and Ankle Society (AOFAS) increased from 49.2 to 88.6. The rate of complications was of 11%. Conclusion Our treatment protocol does not differ much from the classic ones, with similar results as well. We have as advantages less aggression to soft tissues and better cosmetic results. Level of Evidence: level IV, prospective case series.


Resumo Objetivo Apresentar os resultados clínicos e radiográficos da correção cirúrgica de hálux valgo utilizando quatro técnicas percutâneas escolhidas de acordo com uma classificação radiográfica predefinida. Métodos Avaliamos prospectivamente 112 pés em 72 pacientes com hálux valgo operado em um período de um ano. A liberação de tecido mole distal (LTMD) percutâneo e o procedimento de Akin (LTMD-Akin) foram realizados em casos leves. Em hálux valgo de leve a moderado com ângulo distal da articulação do metatarso acima de 10°, adicionamos a osteotomia de Reverdin-Isham (RI). Em casos moderados com incongruência articular, realizamos o chevron percutâneo (CHP). Finalmente, uma osteotomia proximal percutânea fixada (OPPF) com um parafuso, semelhante à de Ludloff, foi proposta em casos graves com ângulo intermetatarsal (AIM) acima de 17°. De acordo com esses critérios, foram realizados 26 LTMDs-Akin, 36 CHPs, 35 RIs e 15 OPPFs. O seguimento médio foi de 17,2 meses (12 a 36 meses). A média de idade em operação foi de 58,8 anos (17 a 83 anos), e 89% dos pacientes eram do sexo feminino. Resultados A média do ângulo de hálux valgo (AHV) pré-operatório e o AIM diminuíram de 21° para 10,2°, e de 11,2° para 10,3°, respectivamente, em casos de LTMD-Akin. Em casos de RI, a média do AHV diminuiu de 26,6° para 13,7°, e o AIM, de 11,2° para 10,3°; em casos de CHP, o AHV médio diminuiu de 31° para 14,5°, o AIM diminuiu de 14,9° para 10,7°, e a OPPF, de 39,2° para 17,7°, e o AIM 11,8° para 6,8°. A média do escore de tornozelo e retropé da American Orthopaedic Foot and Ankle Society (AOFAS) aumentou de 49,2 para 88,6. A taxa de complicação foi de 11%. Conclusão Nosso protocolo de tratamento não difere muito dos clássicos, com resultados semelhantes. Temos como vantagem menos agressividade aos tecidos moles e melhores resultados cosméticos. Nível de evidência: nível IV, série de casos prospectivos.

ABSTRACT

Abstract Objective The present study aims to describe a new weightbearing radiographic method to visualize the heads of the five metatarsals on the coronal plane, evaluating their accuracy through intraclass correlation coefficients. Methods The subjects were evaluated, with weightbearing, with the ankle at 20 degrees of plantar flexion and the metatarsophalangeal joints at 10 degrees of extension, positioned on a wooden device. Two independent foot and ankle surgeons evaluated the radiography, with one of them doing it twice, at different moments, achieving an inter and intraobserver correlation, with intraclass correlation coefficients. Results We radiographed 63 feet, achieving an interobserver correlation coefficient of the radiographic method for the metatarsal heads heights in the coronal plane of the 1st, 2nd, 3rd, 4th, and 5th metatarsals of, respectively, 0.90, 0.85, 0.86, 0.83, 0.89. The intraobserver correlation coefficient were, respectively, 0.95, 0.93, 0.93, 0.86, 0.92. Conclusion Those correlations demonstrate that the method is accurate and can be used to investigate metatarsal head misalignments in this plane.

ABSTRACT

Intermetatarsal coalition (IC) is very rare; although few cases have been reported in foreign orthopedic journals, these have not originated in our country. We report the case of a 20-year-old man who complained of pain in the left forefoot only during long distance running (3 km). On examination, his foot shape, skin appearance, and gait were normal, with no plantar keratosis; however, the radiograph revealed coalition between the fourth and fifth metatarsals. Surgical excision was performed. In the histopathologic study, fibrous coalition was confirmed. This paper reports an uncommon case involving surgical excision of IC in the military service, involving active sport activity.

ABSTRACT

INTRODUCCIÓN: la marcha es una actividad compleja, que requiere de un balance estricto, donde toda la extremidad inferior actúa de manera conjunta para realizar el movimiento y donde el pie es la única parte que actúa sobre el suelo. Por ello cualquier alteración anatómica y biomecánica del pie repercute en la ambulación. OBJETIVO: determinar el grado de correlación funcional ­ radiológica en pacientes tratados mediante osteotomía de scarf. MATERIAL Y MÉTODOS: rstudio correlacional y transversal. Se estudiaron 78 pacientes con diagnóstico de hallux valgus. Se realizó la valoración funcional (Escala AOFAS) y radiológica de todos los pacientes con hallux valgus operados mediante la osteotomía de scarf; se estableció además la correlación entre la valoración funcional y radiológica de cada paciente mediante la prueba de chi cuadrado. RESULTADOS: habiéndose obtenido el valor crítico de Chi ­ cuadrado (X2 c = 12.992), se comprobó que este es menor que el valor del Chi ­ cuadrado calculado, tanto para el ángulo metatarso-falángico (X2 = 40.715) y el ángulo inter-metatarsiano (X2 = 16.539); lo que significa que la hipótesis nula no se aceptó (Los resultados funcionales no se correlacionan con los resultados radiológicos de manera inversamente proporcional). CONCLUSIÓN: se determinó un grado de correlación inverso entre los resultados funcionales y radiológicos en pacientes tratados mediante osteotomía de scarf; α = 0.05; p = 0.95. Significa que a mayor gradación de hallux valgus (leve, moderado y severo), menor es el puntaje de la escala AOFAS (pobre, aceptable, bueno y excelente).


INTRODUCTION: walking is a complex activity, requiring a strict balance, where the entire lower limb acts together to perform the movement and where the foot is the only part that acts on the ground. Therefore, any anatomical and biomechanical alteration of the foot has an impact on the ambulation. OBJECTIVE: to determine the degree of functional ­ radiological correlation in patients treated by the scarf osteotomy. MATERIAL AND METHODS: correlational and cross-sectional study. 78 patients diagnosed with hallux valgus were studied. Functional and radiological (AOFAS Scale) assessment was performed on all patients with hallux valgus operated by scarf osteotomy; the correlation between each patient's functional and radiological assessment was also established using the squared chi test. RESULTS: having obtained the critical value of Chi ­ squared ((X2c x 12,992), it was found that this is less than the value of the Chi ­ calculated square, both for the phalangeal metatarsus angle (X2 x 40.715) and the inter-metatarsal angle (X2 x 16,539); which means that the null hypothesis was not accepted (Functional results do not correlate with radiological results inversely proportional). CONCLUSION: a degree of reverse correlation between functional and radiological results was determined in patients treated with scarf osteotomy; α = 0.05; p = 0.95. ­ meaning that the greater the gradation of hallux valgus (mild, moderate and severe), the lower the AOFAS scale score (poor, acceptable, good and excellent).

ABSTRACT

Resumen: Antecedentes: Hallux valgus (HV) es una desviación en valgo de la articulación metatarsofalángica y en varo del primer metatarsiano. La cirugía pretende reestablecer la congruencia articular, corregir la deformidad y disminuir el dolor. Existe poca literatura de los resultados en población geriátrica. El propósito de este estudio es demostrar que la técnica quirúrgica abierta de Lelièvre y Vidalot logra resultados radiográficos aceptables en dicha población. Material y métodos: 68 pacientes entre 60 y 85 años intervenidos con técnica Lelièvre y Vidalot por HV moderado a severo de Isham, entre Enero 2014 y Enero 2017. Se evaluaron las radiografías preoperatoria, postoperatoria inmediata y a los seis meses, con radiometría convencional para esta afección; todas las mediciones se realizaron en sistema digital. Los datos se ingresaron en Microsoft Excel. Los valores de p < 0.05 se consideraron estadísticamente significativos. Resultados: De 68 pacientes (54 mujeres y 14 hombres), edad media 68.0 años, 12 presentaron afectación bilateral; 28 segundo dedo en garra. El ángulo metatarsofalángico con una media preoperatoria fue 36.6o, incrementado en 100% de los casos de ángulo intermetatarsal 1-2, existiendo una correlación p < 0.05 entre ángulo intermetatarsal y aumento del ángulo metatarsofalángico. Los resultados postquirúrgicos inmediato y a seis meses presentaron una correlación p = 0.3107. Conclusiones: El tratamiento de HV moderado a severo en nuestra población geriátrica bajo técnica Lelièvre y Vidalot logra una corrección aceptable demostrada radiográficamente en el postoperatorio inmediato y a los seis meses, esto traduce una opción viable de tratamiento quirúrgico en dicha población.


Abstract: Background: Hallux valgus (HV) defines a valgo deviation from the metatarsophalangeal joint and in a varo of the first metatarsal. The surgery aims to restore joint congruence, correct deformity and decrease pain. There is little literature on the results in the geriatric population. The purpose of this study is intended to demonstrate that the open surgical technique of Lelièvre and Vidalot achieves acceptable radiographic results in that population. Material and methods: 68 patients between 60 and 85 years of age were involved with Lelièvre Technique and Vidalot for moderate to severe HV of Isham, between January 2014 and January 2017. Immediate postoperative and six month radiographs were evaluated with conventional radiometry for this condition; All measurements were made in digital system. The data was entered in Microsoft Excel. p values < 0.05 were considered statistically significant. Results: Out of 68 patients (54 women and 14 men), average age 68.0 years. 12 had bilateral concern. 28 second finger claw. The metatarsphasopalangic angle with a preoperative mean was 36.6o, increased by 100% of cases of intermetatarsal angle 1-2, with a correlation p < 0.05 between intermetatarsal angle and metatarsal angle increase. Immediate and six-month post-surgical results with a correlation of p = 0.3107. Conclusions: The treatment of moderate to severe HV in our geriatric population under technique Lelièvre and Vidalot achieves an acceptable correction demonstrated radiographically in the immediate postoperative period and at six month, this translates a viable option of surgical treatment in these population.

ABSTRACT

Abstract Objective To determine if the sesamoids migrate laterally in the feet with hallux valgus or if they only appear to move, maintaining their relationship with the other forefoot structures. Methods Anteroposterior radiographs of 80 patients (94 feet, all weight-bearing), from the period between 2015 and 2016, were evaluated. Forty-eight had a valgus hallux angle greater than 15° (hallux valgus group) and 46 presented a hallux valgus angle lower than 15° (control group). The distances from the firstmetatarsus head and the lateral sesamoid bone to the secondmetatarsus axis weremeasured. Subsequently, the coefficients of these distances were determined by the length of the second metatarsus to adjust it for different foot sizes. Results Both the absolute and the relativemeasures from the firstmetatarsus head to the second metatarsus axis were significantly different between the groups, with a positive correlationwith hallux valgus and intermetatarsal angles. However, neither the absolute nor the relative distance of the lateral sesamoid bone to the second metatarsus was different between the groups, as they did not correlate with hallux valgus or intermetatarsal angles. Conclusion Despite the medial deviation of the first metatarsus in hallux valgus, the sesamoid bone maintains its relationship with the second metatarsus in the transverse plane. This apparent lateral displacement may lead to misinterpretation of these radiographs. This fact is of paramount importance in the pre-, intra-, and postoperative period of patients with hallux valgus.


Resumo Objetivo Determinar se os sesamoides migramlateralmente nos pés comhálux valgo ou se apenas aparentam deslocar-se, mantendo sua relação com as demais estruturas do antepé. Métodos Foram avaliadas radiografias na incidência anteroposterior com carga dos pés de 80 pacientes (94 pés) entre o período de 2015 e 2016. Dessas, 48 tinham ângulo de hálux valgo maior do que 15º (grupo hálux valgo) e 46 tinham ângulo de hálux valgo menor do que 15º (grupo controle). Foram medidas as distâncias da cabeça do primeiro metatarso e do sesamoide lateral ao eixo do segundo metatarso. Posteriormente, forammedidos os coeficientes dessas distâncias pelo comprimento do segundo metatarso, a fim de se ajustarem aos diferentes tamanhos de pés. Resultados Tanto a medida absoluta quanto a medida relativa da cabeça do primeiro metatarso ao segundo metatarso foram significativamente diferentes nos dois grupos, tiveram correlação positiva com os ângulos de hálux valgo e intermetatarsal. Contudo, nem a distância absoluta nem a relativa do sesamoide lateral ao segundo metatarso foram diferentes nos dois grupos, bem como não se correlacionaram com os ângulos de hálux valgo e inter-metatarsal. Conclusão Apesar do desvio medial do primeiro metatarso no hálux valgo, o sesamoide mantém sua relação com o segundo metatarso no plano transverso. Esse aparente deslocamento lateral pode levar a interpretação equivocada dessas radiografias. Tal fato é de suma importância no pré-, peri- e pós-operatório dos pacientes com hálux valgo.

ABSTRACT

Abstract Purpose: To investigate the effect of intermittent vibration at different intervals on bone fracture healing and optimize the vibration interval. Methods: Ninety sheep were randomized to receive no treatment (the control group), incision only (the sham control group), internal fixation with or without metatarsal fracture (the internal fixation group), and continuous vibration in addition to internal fixation of metatarsal fracture, or intermittent vibration at 1, 2, 3, 5, 7 and 17-day interval in addition to internal fixation of metatarsal fracture (the vibration group). Vibration was done at frequency F=35 Hz, acceleration a=0.25g, 15 min each time 2 weeks after bone fracture. Bone healing was evaluated by micro-CT scan, bone microstructure and mechanical compression of finite element simulation. Results: Intermittent vibration at 7-day interval significantly improved bone fracture healing grade. However, no significant changes on microstructure parameters and mechanical properties were observed among sheep receiving vibration at different intervals. Conclusions: Clinical healing effects should be the top concern. Quantitative analyses of bone microstructure and of finite element mechanics on the process of fracture healing need to be further investigated.

ABSTRACT

Introducción: La braquimetatarsia es un acortamiento de algún metatarsiano, debido principalmente a una detención prematura del crecimiento de la fisis. Es más frecuente en mujeres, y afecta, sobre todo, al cuarto y al primer metatarsiano. El objetivo de este estudio fue evaluar los resultados del tratamiento mediante alargamiento óseo progresivo con minitutor externo. Materiales y Métodos: Estudio descriptivo retrospectivo. Serie de casos. Se analizaron los resultados de los pacientes operados con esta técnica en nuestro Centro. Se analizaron 6 casos, dos con braquimetatarsia bilateral. Todas eran mujeres y tenían braquimetatarsia del 4.° metatarsiano. El promedio de edad era de 14 años. Se evaluaron los siguientes aspectos: alargamiento en milímetros y complicaciones, como retraso de la consolidación, infección, luxación metatarsofalángica, articulación metatarsofalángica en flexión y satisfacción del paciente. Resultados: Se logró un alargamiento promedio de 15 mm. Dos pacientes tuvieron una infección superficial de las agujas. Una paciente evolucionó con luxación de la articulación metatarsofalángica; otra, con flexión de la articulación metatarsofalángica. No hubo complicaciones neurovasculares. Conclusiones: El alargamiento óseo guiado con tutor externo es un tratamiento seguro y eficaz, además lograría un largo mayor en milímetros que el alargamiento en un tiempo, con un mejor control del alargamiento de partes blandas y estructuras neurovasculares. Todas las complicaciones se resolvieron de manera simple, no afectaron el resultado final del tratamiento. Las complicaciones concuerdan con las descritas en la literatura internacional. Nivel de Evidencia: IV


Introduction: Brachymetatarsia is a shortening of any metatarsal bone, mainly due to premature growth arrest of the growth plate. It is more frequent in women, the fourth and the first metatarsal being the most affected bones. The aim of this study was to evaluate the outcomes of progressive bone lengthening with external mini-fixator. Methods: This is a retrospective, descriptive, case series study in which we analyzed the outcomes of all patients operated on with this technique in our Center. Six cases were evaluated, two of them presented bilateral brachymetatarsia. All patients were women, and had brachymetatarsia of the 4th metatarsal. The average age was 14 years. The following aspects were evaluated: lengthening in millimeters and presence of complications, such as delayed consolidation, infection, metatarsophalangeal joint dislocation, metatarsophalangeal joint in flexion and patient satisfaction. Results: On average, an increase of 15 mm was achieved. Two cases presented superficial infection at the needle insertion site. One patient progressed to metatarsophalangeal joint dislocation, and another one to metatarsophalangeal joint flexion. No neurovascular complications were observed. Conclusions: Bone lengthening with external fixator is a safe and effective treatment. A greater length in millimeters can be achieved in comparison to one-stage lengthening, as well as an improved soft-tissue neurovascular stretching. All complications resolved smoothly and did not affect final treatment results. Complications are similar to those described in the international literature. Level of Evidence: IV

ABSTRACT

BACKGROUND: It is difficult for surgeons to reconstruct soft tissue defects of the great toe. This report aims to evaluate the utility and efficacy of innervated distally based first dorsal metatarsal artery (FDMA) flap with a wide pedicle for reconstruction of soft tissue defects of the great toe. METHODS: This is a retrospective report. Between January 2015 and December 2017, six cases of skin defect of the great toe were reconstructed with an innervated distally based FDMA flap with a wide pedicle. One case was excluded in this report because of chronic pain on the metatarsophalangeal joint due to osteoarthritis before the injury. A total of five cases were evaluated for flap survival and sensory recovery. The sensory recovery was investigated by two-point discrimination and Semmes-Weinstein monofilament tests. The average age of the selected patients was 40 years (range, 36 to 56 years), and the average size of the defect in the toe was 8.3 cm2 (range, 4 to 13.8 cm2). The average follow-up period was 29.4 months (range, 18 to 38 months). RESULTS: All patients survived without any complications. The average two-point discrimination test value was 8.0 ± 0.89 mm (range, 7 to 9 mm), and the average value obtained from the Semmes-Weinstein monofilament test was 4.53 ± 0.33 (range, 4.17 to 4.93). The average residual pain score evaluated with a visual analog scale was 1 (range, 0 to 2). Two patients complained of stiffness in the great toe below 30° of total range of motion during the early stages after surgery, but this stiffness gradually improved after rehabilitation. The average range of motion of three patients with a remaining metatarsophalangeal joint after surgery was 80° (range, 70° to 90°). All five cases could walk regularly without any unique footwear at the final follow-up. CONCLUSIONS: The innervated distally based FDMA flap with a wide pedicle could be a good alternative method for repair of soft tissue defects of the great toe.

ABSTRACT

PURPOSE: To evaluate the efficacy of antibiotic-loaded cement spacers (ALCSs) for the treatment of diabetic foot infections with osteomyelitis as a salvage procedure and to analyze the risk factors of treatment failure. MATERIALS AND METHODS: This study reviewed retrospectively 39 cases of diabetic foot infections with osteomyelitis who underwent surgical treatment from 2009 to 2017. The mean age and follow-up period were 62±13 years and 19.2±23.3 months, respectively. Wounds were graded using the Wagner and Strauss classification. X-ray, magnetic resonance imaging (or bone scan) and deep tissue cultures were taken preoperatively to diagnose osteomyelitis. The ankle-brachial index, toe-brachial index (TBI), and current perception threshold were checked. Lower extremity angiography was performed and if necessary, percutaneous transluminal angioplasty was conducted preoperatively. As a surgical treatment, meticulous debridement, bone curettage, and ALCS placement were employed in all cases. Between six and eight weeks after surgery, ALCS removal and autogenous iliac bone graft were performed. The treatment was considered successful if the wounds had healed completely within three months without signs of infection and no additional amputation within six months. RESULTS: The treatment success rate was 82.1% (n=32); 12.8% (n=5) required additional amputation and 5.1% (n=2) showed delayed wound healing. Bacterial growth was confirmed in 82.1% (n=32) with methicillin-resistant Staphylococcus aureus being the most commonly identified strain (23.1%, n=9). The lesions were divided anatomically into four groups; the largest number was the toes: (1) toes (41.0%, n=16), (2) metatarsals (35.9%, n=14), (3) midfoot (5.1%, n=2), and (4) hindfoot (17.9%, n=7). A significant difference in the Strauss wound score and TBI was observed between the treatment success group and failure group. CONCLUSION: The insertion of ALCSs can be a useful treatment option in diabetic foot infections with osteomyelitis. Low scores in the Strauss classification and low TBI are risk factors of treatment failure.

ABSTRACT

Hallux valgus with metatarsus adductus is difficult to treat and has a higher risk of recurrence after correction. Some treatments for hallux valgus with metatarsus adductus have been reported, but these are extensive procedures with a risk of complications associated with the shortening and malposition of the lesser metatarsals. The technique described here is easier to perform and has several advantages over the previously reported techniques.

ABSTRACT

PURPOSE: A dedifferentiated chondrosarcoma is a rare lethal tumor characterized by a low grade chondrosarcoma juxtaposed with a high grade dedifferentiated sarcoma, such as osteosarcoma, fibrosarcoma. The aim of our study was to document the clinical manifestation and oncologic outcomes of a dedifferentiated chondrosarcoma. MATERIALS AND METHODS: This study identified 11 patients who were diagnosed and treated for dedifferentiated chondrosarcoma between January 2007 and December 2016. The identified cohort was then reviewed regarding age, sex, symptom onset, tumor location, magnetic resonance imagings (MRIs), surgical margin, and pathologic diagnosis. The time to local recurrence and/or metastasis, follow-up duration, and the patients' final status were analyzed. RESULTS: The patients were comprised of 7 males and 4 females with a mean age of 54 years (range, 33–80 years). The location of the tumor was in the femur in 6 cases, pelvis in 4 cases, and metatarsal in 1 case. The average tumor diameter was 12.7 cm (range, 6.0–26.1 cm). At the time of diagnosis, 2 patients showed pathologic fracture; 1 patient was Enecking stage IIA, 9 patients were stage IIB, and 1 patient was stage III. Eight patients were classified as a primary dedifferentiated chondrosarcoma and 3 patients were secondary. One of the primary lesions was misinterpreted initially as a low grade chondroid lesion by MRI and underwent curettage. Local recurrence occurred in 8 cases and distant metastasis occurred in 10 cases with a mean duration of 8 months (range, 2–23 months) and 7 months (range, 1–32 months), respectively. The three-year overall survival of patients with dedifferentiated chondrosarcoma was 18%, and 10 patients died due to disease progression. CONCLUSION: Dedifferentiated chondrosarcoma developed lung metastases in the early period of the clinical courses and the prognosis was dismal.

ABSTRACT

Giant cell tumor is a benign but locally aggressive tumor with common recurrence. Most cases occur around the knee joint. Giant cell tumor of the foot is rare and very few cases involving the first metatarsal have been reported. Its characteristics and treatment in adult patients remain unclear. This paper reports a case of recurrent giant cell tumor at the first metatarsal that was excised surgically and subsequently reconstructed with non-vascularized fibula graft.

ABSTRACT

PURPOSE: Several radiologic reference lines have been used to evaluate individuals with a clubfoot but there is no consensus as to which is most reliable. The aim of this study was to identify which radiologic parameters have relevance to the predictability of additional surgery after Ponseti casting on clubfoot and the effect of clubfoot treatments that contain Ponseti casting and additional surgery. MATERIALS AND METHODS: A total of 102 clubfeet (65 patients, 37 bilateral) were reviewed from 2005 to 2013. The patients were divided into two groups (Group A, those for whom the result of the Ponseti method was successful and did not require additional surgery; and Group B, those for whom the result of the Ponseti method was unsuccessful and required additional surgery), and the following parameters were measured on the plain radiographs: i) talo-calcaneal angle on the anteroposterior and lateral view, ii) talo-1st metatarsal angle on the anteroposterior view, and iii) Tibio-calcaneal angle on the lateral view with the ankle full-dorsiflexion state. Each radiograph was reviewed on two separate occasions by one orthopedic doctor to characterize the intra-observer reliability, and the averages were analyzed. Next, 20 cases were chosen using a random number table, and two orthopedic doctors measured the angle separately to characterize the inter-observer reliability. RESULTS: Groups A and B included 73 clubfeet (71.6%) and 29 clubfeet (28.4%), respectively. The initial talo-calcaneal angle and tibio-calcaneal angle in the lateral view were significantly different among the groups. In addition, inter- and intra-observer biases were not detected. The talo-1st metatarsal angle on the anteroposterior view and tibio-calcaneal angle on the lateral view were significantly different after treatment in both groups. CONCLUSION: Congenital clubfeet treated with the Ponseti method showed successful results in more than 70% of patients. The initial talo-calcaneal angle and tibio-calcaneal angle on the lateral view were the radiologic parameters that could predict the need for additional surgical treatments. The talo-1st metatarsal angle on the anteroposterior view and tibio-calcaneal angle on the lateral view could effectively evaluate the changes in clubfoot after treatment.

ABSTRACT

Forefoot disorders are often seen in clinical practice. Forefoot deformity and pain can deteriorate gait function and decrease quality of life. This review presents common forefoot disorders and conservative treatment using an insole or orthosis. Metatarsalgia is a painful foot condition affecting the metatarsal (MT) region of the foot. A MT pad, MT bar, or forefoot cushion can be used to alleviate MT pain. Hallux valgus is a deformity characterized by medial deviation of the first MT and lateral deviation of the hallux. A toe spreader, valgus splint, and bunion shield are commonly applied to patients with hallux valgus. Hallux limitus and hallux rigidus refer to painful limitations of dorsiflexion of the first metatarsophalangeal joint. A kinetic wedge foot orthosis or rocker sole can help relieve symptoms from hallux limitus or rigidus. Hammer, claw, and mallet toes are sagittal plane deformities of the lesser toes. Toe sleeve or padding can be applied over high-pressure areas in the proximal or distal interphalangeal joints or under the MT heads. An MT off-loading insole can also be used to alleviate symptoms following lesser toe deformities. Morton's neuroma is a benign neuroma of an intermetatarsal plantar nerve that leads to a painful condition affecting the MT area. The MT bar, the plantar pad, or a more cushioned insole would be useful. In addition, patients with any of the above various forefoot disorders should avoid tight-fitting or high-heeled shoes. Applying an insole or orthosis and wearing proper shoes can be beneficial for managing forefoot disorders.

ABSTRACT

OBJECTIVE@#To explore distal Chevron osteotomy of the first metatarsal and soft-tissue release for the treatment of mild and moderate hallux valgus.@*METHODS@#From June 2015 to June 2017, 32 patients(40 feet) with mild and moderate hallux valgus were treated with distal Chevron osteotomy with soft tissue release. including 3 males(3 feet) and 29 females (37 feet), aged from 22 to 80 years old with an average of 57.57 years old. The courses of disease ranged from 2 to 32 years with an average of 14 years. Among them, 9 feet were mild, 31 feet were moderate. Patients were combined with bunion, pain around the first metatarsal joint, and pain increased during weight-bearing walking before opertaion. AP and lateral X-rays on weight-bearing were performed, hallux valgus angle(HVA) and intermetatarsal angle(IMA) between the first and the second metatarsal were examined before and after operation. AOFAS score was applied to evaluate clinical effects.@*RESULTS@#All patients were followed up from 12 to 24 months with an average of 15.2 months.Fracture wounds were healed well without infection and metatarsal head necrosis occurred. Preoperative HVA (32.08±5.59)° and IMA (11.63±2.24)° decreased to (10.31±4.36)° and (5.02°±2.34)°after operation at 12 months, and had statistical difference before and after operation (<0.05). AOFAS score increased from 56.75±6.42 before operation to 88.80±3.99 after operation at 12 months(<0.05).@*CONCLUSIONS@#Distal Chevron osteotomy of the first metatarsal and soft-tissue release for the treatment of mild and moderate hallux valgus could obtain good effects and provide more options for hallux valgus treatment.

ABSTRACT

As one of the most common fractures of the foot, the blood supply characteristics and unique anatomy of proximal fifth metatarsal fracture makes a high risk of delayed union or non-union of fractures occurring at the junction of the diaphyseal-metaphyseal. At present, the classification system of proximal fifth metatarsal fracture is complicated and not yet unified, and Lawrence and Botte classification is more recommended. The system divides proximal fifth metatarsal fracture into three types:avulsion fractures of tuberosity(Zone I), fractures at the metaphysis-diaphysis junction, which extend into the fourth-fifth intermetatarsal facet (Zone II) and the proximal diaphyseal fractures(Zone III). Based on the classification system, each type of fracture has a corresponding treatment plan and prognosis. There are a variety of surgical methods for proximal fifth metatarsal fracture. For the fracture of Zone II and Zone III, percutaneous intramedullary screw is the first choice. In addition, clinicians should also have a thorough understanding of common complications of fracture and associated disposal methods.
