ABSTRACT

Hallux valgus is considered the most common musculoskeletal deformity, with a prevalence of 88%. There are more than 130 surgical techniques for its treatment; currently, percutaneous ones are popular; however, they do not take into account the metatarsal-phalangeal correction angle. The aim of this study is to propose a modified technique for the correction of the percutaneous metatarsal-phalangeal and inter-metatarsal angles and to evaluate its clinical and radiological results. MATERIAL AND METHODS: An experimental, prospective and longitudinal study in 10 patients with moderate to severe hallux valgus according to the classification of Coughlin and Mann were collected; the results were evaluated with the AOFAS scale at 15, 30, 60 and 90 days. The McBride technique and the technique of percutaneous anchor with the proposed amendment were performed. RESULTS: The AOFAS scale was applied as described, finding a progressive increase of the rating; the average correction of the inter-metatarsal angle was 8.8 degrees and of the metatarsal-phalangeal, 9.12. DISCUSSION: The modified technique of percutaneous anchor showed clear clinical and radiographic improvements in the short term. Our modified technique is proposed for future projects, including a large sample with long-term follow-up.


El hallux valgus es considerado la deformidad del aparato locomotor más frecuente, con una prevalencia de 88%. Existen más de 130 técnicas quirúrgicas para su tratamiento; actualmente se encuentra de moda el uso de técnicas de anclaje percutáneas; sin embargo, no toman en cuenta la corrección del ángulo metatarsofalángico. El objetivo del siguiente estudio es mostrar la técnica modificada de anclaje percutáneo con corrección del ángulo metatarsofalángico e intermetatarsiano, así como la evaluación clínica y radiológica. Material y métodos: Se realizó un estudio experimental, prospectivo y longitudinal en una muestra de 10 pacientes con el diagnóstico de hallux valgus moderado a severo según la clasificación Coughlin y Mann; se evaluaron los resultados con la escala de AOFAS a los 15, 30, 60 y 90 días. Se realizaron las técnicas de McBride y de anclaje percutáneo con la modificación propuesta. Resultados: La escala AOFAS mostró un aumento progresivo de la puntación; la corrección media del ángulo intermetatarsiano fue de 8.8 grados y del metatarsofalángico, 9.12. Discusión: La técnica modificada de anclaje percutáneo mostró evidente mejoría clínica y radiográfica en el seguimiento de los pacientes, lo que comprueba que es una técnica aceptable a mediano plazo. Nuestra técnica modificada se desarrollará como una línea de investigación a futuro con un mayor número de pacientes y seguimiento a largo plazo.

ABSTRACT

OBJECTIVE: The aim of this study was to determine the healing time of Achilles tendon in pediatric patients treated with Achilles tenotomy with the Ponseti method in Shriners Childrens Hospital of Mexico, AC. MATERIAL AND METHODS: Experimental, analytical, prospective, longitudinal study of patients with a diagnosis of idiopathic congenital clubfoot treated with the Ponseti method with serial static and dynamic evaluation by ultrasound in real time with a Siemens Diagnostic Ultrasound System Sonoline 650, linear transducer 10.5 MHz of Achilles tendon before tenotomy and at three, six, nine and 12 weeks after the surgical treatment. RESULTS: A sample of 23 patients, 16 male and seven female, 16 with unilateral and seven with bilateral pathology was obtained, for a total of 39 feet, 18 right and 21 left, with a mean age of 8.3 ± 2.3 months. Before tenotomy, the width was 2.7 ± 0.42 mm; in week three, the average was 3 ± 0.39 mm; at six weeks, 2.92 ± 0.36 mm; ultrasound at nine weeks reported an average of 0.38 ± 2.84 mm, and 2.82 ± 0.39 mm at twelve weeks. They were compared using Students t presurgical width and at twelve weeks, without finding difference p 0.03. CONCLUSIONS: Although there is integrity at three weeks after Achilles tenotomy, complete repair is achieved at 12 weeks.

ABSTRACT

OBJECTIVE: The aim of this study was to evaluate the functional and radiographic results of adolescent patients with angular deformities of the pelvic limbs treated with an open wedge osteotomy system. MATERIAL AND METHODS: Observational, prospective, analytical and cross-sectional study of patients with angular deformity of the pelvic limbs treated with an open wedge osteotomy. We made a radiographic evaluation of the femorotibial angle, MAD angle, lower limb discrepancy, and pre- and postoperative degrees of the rotational center of deformity (CORA), as well as a telephone survey of the postoperative functional evaluation IKDC 2000. RESULTS: It was a sample of 28 patients, 21 female and seven male, with a mean age of 15.3 years. Their diagnoses: idiopathic genu valgo, 10 cases; Blount disease, four; benign tumors (enchondromatosis and osteochondromatosis), three; hypophosphatemic rickets; three, among others, such as sequelae of septic arthritis of the knee, femoral hypoplasia, and fracture sequels. It was a total of 29 osteotomies, 17 of the tibia and 12 of the femur; 17 osteotomies presented deviation to lateral of the mechanical axis, and 11, medial deviation, with a mean femorotibial angle of 17 and 7.35 (p 0.03), respectively. The mean initial discrepancy had an improvement of 0.5 cm. Postoperative IKDC in the subjective evaluation had an average of 95.3 points. CONCLUSIONS: The fixation of osteotomies with open wedge plates is an option with good clinical and radiographic results.

ABSTRACT

The objective of this study was to evaluate the association between in utero exposure to fluoride (F) and Mental and Psychomotor Development (MDI and PDI) evaluated through the Bayley Scale of Infant Development II (BSDI-II) in infants. The sample included 65 mother-infant pairs. Environmental exposure to F was quantified in tap and bottled water samples and F in maternal urine was the biological exposure indicator; samples were collected during the 1st, 2nd and 3rd trimester of pregnancy. The mean values of F in tap water for the 1st, 2nd and 3rd trimester were 2.6±1.1mg/l, 3.1±1.1mg/l and 3.7±1.0mg/l respectively; above to 80% of the samples exceeded the reference value of 1.5mg/l (NOM-127-SSA1-1994). Regarding F in maternal urine, mean values were 1.9±1.0mg/l, 2.0±1.1mg/l and 2.7±1.1mg/l for the 1st, 2nd and 3rd trimester respectively. The infants with MDI and PDI scores less than 85 points were 38.5% and 20.9% respectively. After adjusting for potential confounding factors (gestational age, age of child, marginalization index and type of water for consumption), the MDI showed an inverse association with F levels in maternal urine for the first (ß=-19.05, p=0.04) and second trimester (ß=-19.34, p=0.01). Our data suggests that cognitive alterations in children born from exposed mothers to F could start in early prenatal stages of life.

ABSTRACT

The main function of the forearm is the supination, which is achieved largely through the biomechanical characteristics and stability of the distal radio-ulnar joint. There are several surgical techniques for the treatment of distal radio-ulnar dislocations isolated or associated with a fracture. We report the case of a canine trainer who was bitten at the wrist and distal forearm that came to the emergency department in where distal ulnar dislocation with muscle tendon exposure was diagnosed. Due to the offending agent and multiple soft tissue injuries the treatment with standard techniques was impossible. We describe the technique of treatment of this patient by placing autologous gracilis tendon graft, platelet rich plasma and two anchoring systems for ankle syndesmosis. Immobilization was maintained for six weeks with a subsequent rehabilitation and posterior valuation at 12, 18 and 28 weeks by the scale of MAYO, PRWE and DASH and finding a good result which implies the return to work and daily activities of the patient with minimal pain and limitation.


La función principal del antebrazo es la pronosupinación, la cual se logra en gran medida mediante la estabilidad y características biomecánicas de la articulación radio-cubital distal. Existen diversas técnicas quirúrgicas para el tratamiento de las luxaciones radio-cubitales distales aisladas o asociadas con fractura. Presentamos el caso de un paciente entrenador canino quien fue mordido a nivel de la muñeca y antebrazo distal acudiendo al Servicio de Urgencias en donde se diagnostica una luxación cubital distal con exposición músculo tendinosa. Debido al agente lesivo y las múltiples lesiones de partes blandas resultó imposible realizar las técnicas habituales de tratamiento. Se describe la técnica utilizada para el manejo de este paciente mediante la colocación de injerto tendinoso autólogo de gracilis, plasma rico en plaquetas y dos sistemas de anclaje para sindesmosis de tobillo. Se inmovilizó por seis semanas e inició rehabilitación subsecuente y valorándolo a las 12, 18 y 28 semanas mediante la escala de MAYO, DASH y PRWE encontrando un resultado bueno que implica la reincorporación a las actividades laborales y cotidianas del paciente con un mínimo dolor y limitación.

ABSTRACT

Introducción: El flúor (F) es un elemento tóxico y reactivo; la exposición al mismo pasa casiinadvertida con el consumo de té, pescado de mar, carnes, frutas, etc., y el uso de artículoscomo aditivo en pastas de dientes, enjuagues bucales, antiadherentes sobre sartenes y hojas deafeitar como el teflón. Asimismo, ha sido utilizado con la intención de reducir la caries dental.Desarrollo: El F puede acumularse en el organismo y se ha demostrado que la exposicióncrónica al mismo produce efectos nocivos sobre distintos tejidos del organismo y de maneraparticular sobre el sistema nervioso, sin producir malformaciones físicas previas.Fuentes: Diversos trabajos, tanto clínicos como experimentales, han reportado que el Fprovoca alteraciones sobre la morfología y bioquímica cerebral, que afectan el desarrollo neurológicode los individuos y, por ende, de funciones relacionadas con procesos cognoscitivos,tales como el aprendizaje y la memoria.Las toxicidad del F se puede presentar a partir de la ingesta de 1 parte por millón (ppm) ylos efectos no son inmediatos ya que pueden tardar 20 a˜nos o más en manifestarse.Conclusión: La ingesta prolongada de F provoca da˜nos a la salud y de manera importante sobreel sistema nervioso central, por lo que es importante considerar y evitar el uso de artículos quecontengan flúor y de manera particular en individuos en desarrollo, debido a la susceptibilidadque presentan a los efectos tóxicos del F (AU)


Introduction: Fluoride (F) is a toxic and reactive element, and exposure to it passes almostunnoticed, with the consumption of tea, fish, meat, fruits, etcetera and articles of commonuse such as: toothpaste additives; dental gels, non-stick pans and razor blades as Teflon. It hasalso been used with the intention of reducing the dental cares.Development: Fluoride can accumulate in the body, and it has been shown that continuousexposure to it causes damaging effects on body tissues, particularly the nervous system directlywithout any previous physical malformations.Background: Several clinical and experimental studies have reported that the F induces changesin cerebral morphology and biochemistry that affect the neurological development ofindividuals as well as cognitive processes, such as learning and memory. F can be toxic byingesting one part per million (ppm), and the effects they are not immediate, as they can take20 years or more to become evident.Conclusion: The prolonged ingestion of F may cause significant damage to health and particularlyto the nervous system. Therefore, it is important to be aware of this serious problem andavoid the use of toothpaste and items that contain F, particularly in children as they are moresusceptible to the toxic effects of F (AU)
