[Translated article] Better results in consolidation of hallux metatarsophalangeal arthrodesis with dorsal plate and interfragmentary compression screw.

BACKGROUND AND AIMS: The first metatarsophalangeal joint arthrodesis is indicated for the treatment of various pathologies as a technique to reduce pain and improve the support of the first radius. Numerous surgical techniques and fixation methods have been described, with the combination of a dorsal plate and an interfragmentary screw being the one that has shown to be the most stable construct in biomechanical studies. Our aim is to analyze the radiological results after metatarsophalangeal arthrodesis of the hallux using a dorsal plate associated or not with an interfragmentary screw. The differences in terms of consolidation rates and complications in patients diagnosed with hallux rigidus, hallux valgus, hallux varus and failure of previous surgeries were evaluated. MATERIALS AND METHODS: A retrospective cohort study of 55 patients with a mean age of 65.10 years in whom a dorsal plate was used was performed. Patients were divided into two groups depending on whether or not an interfragmentary screw was used. The minimum follow-up was 6 months after surgery. The assessment of the pre and postoperative radiological results was based on the variation of the hallux angle, the intermetatarsal angle and the dorsal metatarsophalangeal angle of the hallux, as well as the cases of nonunion identified in each study group. RESULTS: The radiological results, statistically significant differences (p<0.05) were only found in the dorsal metatarsophalangeal angle between both study groups. No statistically significant differences were found regarding the radiological evaluation of the pre and postoperative hallux angle and intermetatarsal angle. An equal decrease of each angles was observed in both study groups. Regarding the consolidation rate, statistically significant differences (p<0.05) were found between group A, which associated an interfragmentary screw, presenting a consolidation rate of 92%, and group B, which did not associate an interfragmentary screw, and that presented a union rate of 63%. CONCLUSION: Hallux metatarsophalangeal arthrodesis of the hallux with a dorsal plate and interfragmentary screw show best results regarding consolidation rate and complications compared to those cases in which an interfragmentary screw was not used.

La configuración de los tornillos en la osteosíntesis de las fracturas del cuello femoral no influye en los resultados funcionales ni mecánicos / The configuration of the screws in the osteosynthesis of fractures of the femoral neck does not influence the functional or mechanical outcomes

Antecedentes y objetivo: La síntesis con tornillos canulados es uno de los métodos aceptados en las fracturas de cuello femoral, aunque su óptima disposición es un tema en continuo debate. El objetivo principal fue comparar los resultados del paciente con fractura de cuello de fémur fijada con tres tornillos en configuración triangular y en triángulo invertido en el plano frontal. Materiales y métodos: Estudio retrospectivo y comparativo de 53 pacientes con fractura de cuello femoral intervenidos entre 2015 y 2022 mediante fijación con tres tornillos canulados: 22 conformados en triángulo (grupo triángulo) y 31 en triángulo invertido (grupo triángulo invertido). Se evaluó la funcionalidad mediante la escala modificada de Merlé d’Aubigné, la capacidad para la deambulación con la escala de Koval, así como las complicaciones postoperatorias. Resultados: En la escala de Merlé d’Aubigné la puntuación media fue de 16,7 en el grupo triángulo y de 16,1 en el grupo triángulo invertido (p=0,259). En la escala de Koval se observó una disminución significativa, pasando de 1,6 de media preoperatoria a 2,2 tras la cirugía (p=0,000), no hallando diferencias entre grupos. Hubo seis complicaciones postoperatorias en el grupo triángulo y tres en el grupo triángulo invertido (p=0,140). Conclusión: La configuración de los tornillos en el cuello femoral, tanto en forma de triángulo como en triángulo invertido, no influyó en los resultados funcionales ni mecánicos de los pacientes con fractura de cuello de fémur fijada mediante tres tornillos canulados.(AU)

Background and objective: Synthesis with cannulated screws is one of the accepted methods in femoral neck fractures, although its optimal configuration is a subject in continuous debate. The main objective was to compare the results of the patient with a femoral neck fracture fixed with three screws in triangle and inverted triangle configuration in the frontal plane. Materials and methods: Retrospective and comparative study of 53 patients with femoral neck fracture, operated between 2015 and 2022 with fixation with three cannulated screws, 22 with a triangle configuration (triangle group) and 31 in an inverted triangle (inverted triangle group). Functionality was evaluated using the modified Merlé d’Aubigné scale, walking ability using the Koval scale, as well as postoperative complications. Results: On the Merlé d’Aubigné scale, the mean score was 16.7 in the triangle group and 16.1 in the inverted triangle group (P=.259). On the Koval scale, a significant decrease was observed, going from 1.6 preoperative mean to 2.2 after surgery (P=.000), finding no differences between groups. There were six postoperative complications in the triangle group and three in the inverted triangle group (P=.140). Conclusion: The configuration of the screws in the femoral neck, both in the form of a triangle and an inverted triangle, did not influence the functional or mechanical outcomes of the patients with a femoral neck fracture fixed with three cannulated screws.(AU)

ABSTRACT Objective: To relate the radiographic fusion rate and the surgical results in patients undergoing posterolateral arthrodesis with instrumentation of the lumbar spine for the treatment of degenerative disorders. Method: A descriptive, retrospective, case series, observational study, based on medical records and imaging studies of 76 patients over 18 years of age (39 to 88 years) who underwent posterolateral lumbar arthrodesis. Data related to the presence of comorbidities were compiled and clinical outcomes were measured using specific questionnaires collected pre-surgical and 1 year after surgery. Fusion quality, as described by Christensen, was assessed from radiographic images by two examiners. The VAS, EQ-5D and Roland Morris questionnaires were used preoperatively and 1 year after surgery to assess pain, quality of life and function, respectively. Result: It was observed improvement in pain, function and quality of life after 1 year post-surgical. Pain, measured by VAS, had a reduction from 7.92 to 3.16 (p-value <0.001), the function evaluated by the Roland Morris score, also showed a reduction from 14.90 to 7.06 (p-value <0.001) . Culminating with the improvement in quality of life, measured by the EQ-5D, where there was a median increase in the score from 0.5672 to 0.7002 (p-value = 0.002). Conclusion: The absence of radiographic fusion has no direct correlation with worse results in clinical outcomes at 01 year after surgery. Most patients showed clinical improvement with no statistical difference in relation to cases in which bone fusion was obtained. Level of evidence IV; retrospective observation.

Artrodesis transcalcánea con injerto libre del peroné por seudoartrosis de tibia distal / Transcalcaneal Arthrodesis with Free Fibula Graft for Distal Tibial Nonunion

RESUMEN Introducción: Las fracturas abiertas del tercio distal de tibia o pilón son poco frecuentes, en nuestro medio se producen por traumas de alta energía como los accidentes de tránsito, y pueden ser de distintos grados según su envergadura. Entre las complicaciones frecuentes están la seudoartrosis, deformidades y artritis postraumática. Cuando el dolor es refractario a los analgésicos están indicadas las artrodesis. Objetivo: Presentar los resultados del tratamiento realizado en un paciente con seudoartrosis distal de tibia y artritis postraumática del tobillo, dolorosa, con gran lesión de partes blandas, por lo que fue imposible realizar los procedimientos quirúrgicos habituales. Presentación del caso: Se realizó artrodesis de las articulaciones tibio-peronea-astragalina-calcánea, mediante un injerto libre del peroné autólogo, compresión, y estabilización con un fijador externo RALCA®; se asoció un campo electromagnético pulsátil para acelerar la formación del callo óseo y disminuir el dolor posquirúrgico. Durante dos años se le hizo seguimiento. Conclusiones: Se logró el objetivo del tratamiento al fusionar la articulación tibiotarsiana, comenzar el apoyo precoz y su capacidad funcional. Los resultados demuestran además los beneficios de la compresión realizada con los fijadores externos en las artrodesis; el uso del campo electromagnético asociado aceleró la osteogénesis, se consiguió la consolidación ósea, la estabilización, disminuyó el edema y el dolor, además la reincorporación del paciente a la sociedad. No se encontró en la bibliografía revisada otra técnica quirúrgica similar(AU)

ABSTRACT Introduction: Open fractures of the distal third of the tibia or pilon are rare, in our environment they are caused by high-energy traumas such as traffic accidents, and can be of different degrees depending on their size. Common complications include nonunion, deformities, and post-traumatic arthritis. When pain is refractory to analgesics, arthrodesis is indicated. Objective: To report the results of the treatment carried out in a patient with distal tibial pseudoarthrosis and post-traumatic arthritis of the ankle, painful, with a large soft tissue injury, which made it impossible to perform the usual surgical procedures. Case report: Arthrodesis of the tibiofibular-talar-calcaneal joints was performed, using a free graft of the autologous fibula, compression, and stabilization with a RALCA® external fixator. A pulsatile electromagnetic field was associated to accelerate bone callus formation and reduce postoperative pain. This patient was followed up for two years. Conclusions: The treatment objective was achieved by fusing the tibiotarsal joint, by starting early support and functional capacity. The results also prove the benefits of compression performed with external fixators in arthrodesis. The use of the associated electromagnetic field accelerated osteogenesis, bone consolidation and stabilization were achieved, edema and pain decreased, as well as the patient's reincorporation into society. No other similar surgical technique was found in the reviewed literature(AU)

Secondary reconstruction of pseudoarthrosis of the astragalus body after undiagnosed fracture. / Reconstrucción secundaria de seudoartrosis del cuerpo del astrágalo tras fractura no diagnosticada.

Pseudoarthrosis is a complication that occurs in up to 12% of astragalus fractures. In this situation, 2main treatment options are considered: arthrodesis and secondary reconstruction. In this text we present the case of a patient who suffered this complication after not being diagnosed with the fracture he suffered and opted for secondary reconstruction with good results. Fracture nonunion affects up to 12% of patients suffering a talar fracture. Classically, most authors proceed to joint arthrodesis when facing such complication. A more recent approach consists on secondary reconstruction of the nonunion. In this paper we present the case of a reconstructed talar nonunion after an unnoticed talar body fracture with encouraging results.

Materiales & Métodos Serie de casos en un centro de cuarto nivel de complejidad entre el 2005 y 2016 de pacientes con fractura de escafoides en seudoartrosis sometidos a cirugía de revisión con injerto vascularizado de la primera arteria dorsal metacarpiana según la técnica de Bertelli. Se tomaron datos de historias clínicas, que se analizaron con medidas descriptivas de resumen. Resultados se analizaron 11 pacientes con una edad promedio de 30,1 años. El 72,7% fue llevado a osteosíntesis como manejo inicial. El procedimiento de revisión se realizó en una mediana de 380 días. Se reportaron complicaciones pos-quirúrgicas: necrosis del injerto en un paciente, necesidad de re-intervención en cuatro y no hubo infecciones. En el 72,7% se observó consolidación de la fractura y ocurrió en promedio a los 7,6 meses. La mitad de los pacientes tuvieron un puntaje DASH de 9 o menos y reportaron percepción de dolor leve - moderado el 90,9%. La mediana de seguimiento fue 14 meses. Discusión la ventaja de esta técnica es su reproducibilidad y versatilidad, pues su pedículo vascular constante y de buena longitud, permite utilizarse por un abordaje dorsal o palmar y para no consolidaciones del polo proximal, cintura o polo distal del escafoides. Este estudio mostró buenos resultados clínicos y funcionales, asociados a una baja tasa de complicaciones. Nivel de evidencia IV

Background The aim of study is to describe the clinical, functional, and radiological results in patients with pseudoarthrosis of scaphoid fractures who that underwent surgery using Bertelli's et al. technique. Methods Case series of patients with nonunion of scaphoid fractures in a high complexity care center between 2005 and 2016, who underwent revision surgery with vascularized bone graft of the first metacarpal dorsal artery according to Bertelli's et al. technique. Data were collected from clinical records, and it waswere analyzed using descriptive summary measures. Results The analysis included 11 patients with a mean age of 30,1 years (S.D: 9). 72,7% of the patients underwent conventional osteosynthesis as the initial approach. The revision surgery was performed with a median of 380 days (interquartile range: 194-470); there were no intraoperative complications. Post- surgery complications, such as graft necrosis, were reported in a one patient (9,1%), the need of for re-intervention in four patients and there were no infection related complications. Fracture union was seen in 72,7% patients in a mean of 7,6 months (S.D: 2,9) after the intervention. Half of the patient had a DASH score of 9 points or less. 54,5 reported pain as mild, 36,4% as moderate and without pain 9,1%. The median follow up period was 14 months and only one patient developed carpal arthritis. Discussion The advantage of this surgical technique is its reproducibility and versatility, thanks due to the constant and long vascular pedicle; this allows using dorsal or palmar approaches, as well as for the management of scaphoid nonunions of the proximal pole, waist, or distal pole. This study shows good clinical and functional results outcomes with a low rate of complications. Evidence Level IV

Trends and attitudes of spine surgeons regarding osteoporosis. / Tendencias de actuación de los cirujanos de columna respecto a la osteoporosis.

BACKGROUND AND OBJECTIVES: Neurosurgeons and other specialists are increasingly having to treat patients with osteoporosis who require spinal fusion surgery. Although there are effective pharmacological treatments and innovations in surgical techniques that can benefit these patients, low rates of diagnosis and preoperative treatment of osteoporosis have been reported, in addition to the limited participation of spine surgeons in this area. The objective of this study was to evaluate trends in diagnosis and treatment of osteoporosis with regard to spine surgeons of the neurosurgical community. MATERIAL AND METHODS: An electronic survey with 10 multiple-choice questions was issued to Spanish Neurosurgery Society (SENEC) members. The following were evaluated: 1) the surgeon's role regarding osteoporosis in spinal arthrodesis, 2) the influence of osteoporosis in pseudarthrosis, and 3) treatment trends in relation to osteoporotic vertebral fractures. RESULTS: A total of 77 completed questionnaires were obtained. In patients with suspected osteoporosis, 32.5% of respondents did not consider any measure to diagnose it before spinal arthrodesis. In osteoporosis without treatment, 37.7% would proceed with surgery without treatment or would do so after surgery. A total of 48% of respondents would choose to modify their surgical strategy in patients with osteoporosis. The preferred surgical technique was the placement of augmentation screws (70%). In pseudarthrosis, 46.1% did not consider an osteoporosis diagnosis to be necessary for a reoperation. In osteoporotic vertebral fractures, 80.5% of surgeons considered some measure that would facilitate the treatment of osteoporosis. CONCLUSIONS: Greater participation of the spine surgeon could improve the diagnosis and preoperative treatment of osteoporosis in spinal arthrodesis surgery and pseudarthrosis. In vertebral fractures, there is greater awareness of the optimisation of treatment and monitoring of osteoporosis.

Arthroscopic reconstruction for unstable scaphoid non-union. / Reconstrucción artroscópica de la seudoartrosis inestable del escafoides carpiano.

OBJECTIVE: To evaluate the results of arthroscopic reconstruction for the treatment of unstable scaphoid non-union with cancellous bone autograft. METHODS: 13 patients were treated with a mean age of 26 (18-45) years. The average time from injury until surgery was 14 (6-48) months. Preoperative and postoperative clinical and radiological parameters were evaluated. Mean follow-up was 16.8 (12-36) months. RESULTS: Consolidation was achieved in all cases at 7 (4-10 weeks), no patient had complications or reoperations. Range of motion, pain, functional assessment (DASH questionnaire) and radiological measurements improved compared to preoperative measurements. The average range of flexion improved: flexion 71.9° (55°-80°) to 81.7° (55°-90°), extension 66.3° (30°-80°) to 84.4° (70° -90°), ulnar deviation 21.5 (10°-25°) to 25.5° (20°-45°) and radial deviation 11.9° (5°-25°) to 13.3° (10th-20th). Pain (VAS 0-10) improved from 6.8 (4-10) to 0.7 (0-3). DASH functional scale improved from 36 (12-78) to 8 (0-10). The Scapho-Lunate Angle improved from 67.7° (62°-88°) to 47° (32°-55°), and the Radio-Lunate Angle improved from 30.8° (10° -45°) to 4(0°-10°). CONCLUSION: Treatment of unstable scaphoid non-union with cancellous bone graft assisted by arthroscopy presents good clinical results with a short period of consolidation and recovery.

Descripción de los factores de riesgo biológicos para pseudoartrosis / Description of the biological risk factors for pseudarthrosis

Objetivo: describir las características clínicas y quirúrgicas que pueden catalogarse como factores de riesgo biológico en el desarrollo de seudoartrosis en los pacientes con fracturas de tibia y fémur tratados con o sin cirugía. Materiales y métodos: estudio de corte transversal; se revisaron los factores de riesgo biológico en seudoartrosis por fracturas de tibia y fémur en las historias clínicas de los hospitales de San José e Infantil Universitario de San José de Bogotá, Colombia. Se utilizó estadística descriptiva para el análisis. Resultados: Se incluyó a 91 pacientes tratados inicialmente con osteosíntesis. De los factores de riesgo evaluados, el 41,8% fue fumador, el 8,9% consumió medicamentos asociados con el riesgo de desarrollar seudoartrosis y el 8,8% presentaba alguna comorbilidad. El tutor externo fue el tipo de osteosíntesis más usado (37,4%). La mediana de tiempo para la cura de seudoartrosis fue de 9 meses (IQR 6-11). Discusión: los factores que afectan al proceso de consolidación se clasifican en mecánicos y biológicos. Como fortaleza se destaca que es el primer reporte local sobre los factores de riesgo biológico, excluyendo los de tipo mecánico, que pueden contribuir por otras vías a la generación de seudoartrosis. Conclusión: Al identificar y conocer los factores de riesgo biológicos para el desarrollo de esta patología, se puede lograr una intervención temprana que defina la terapia apropiada y favorezca un buen pronóstico.

Objective: To describe the clinical and surgical features which may be classified as biological risk factors for the formation of pseudarthrosis in patients with tibia and femur fractures receiving surgical or non-surgical treatment. Materials and methods: Cross-sectional study. The biological risk factors for bone non-union secondary to tibia and femur fractures in patients seen at the San José and Infantil Universitario de San José hospitals in Bogotá Colombia were identified by reviewing their clinical records. Descriptive statistics were used to analyze the data. Results: 91 patients initially receiving a surgical fixation were included. The risk factors identified were, 41.8% of patients smoked, 8.9% received medication associated with the risk of delaying fracture healing and 8.8% had comorbidities. The external tutor was the most used type of fixation (37.4%). The median time to non-union healing was 9 months (IQR 6 -11). Discussion: The factors affecting bone healing processes are classified as mechanical and biological. A positive feature of our study is that it is the first local report on biological risk factors, excluding mechanical risk factors which in other ways favor fracture non-union. Conclusion: Early identification and knowledge of biological risk factors for pseudarthrosis promotes a timely intervention and defining an adequate treatment providing a good prognosis.

Correlation between quality of life and osteolysis around lumbar pedicle screws / Relação entre qualidade de vida e osteólise em torno de parafusos pediculares lombares / Correlación entre calidad de vida y osteólisis alrededor de tornillos pediculares lumbares

ABSTRACT Objective: To evaluate whether the presence of osteolysis around the pedicle screws affects the quality of life of patients who underwent posterolateral arthrodesis of the lumbosacral spine. Methods: A retrospective study of patients undergoing lumbar posterolateral or lumbosacral arthrodesis due to spinal degenerative disease. CT scans of the operated segments were performed at intervals of 45, 90, 180, and 360 postoperatively. In these tests, the presence of a peri-implant radiolucent halo was investigated, which was considered present when greater than 1mm in the coronal section. Concurrently with the completion of CT scans, the participants completed the questionnaire Oswestry Disability Index (ODI) to assess the degree of disability of the patients. Results: A total of 38 patients were evaluated, and 14 (36.84%) of them showed some degree of osteolysis around at least one pedicle screw at the end of follow-up. Of the 242 analyzed screws, 27 (11.15%) had osteolysis in the CT coronal section, with the majority of these occurrences located at the most distal level segment of the arthrodesis. There was no correlation between the presence of the osteolysis to the quality of life of patients. The quality of life has significantly improved when comparing the preoperative results with the postoperative results at different times of application of ODI. This improvement in ODI maintains linearity over time. Conclusion: There is no correlation between the presence of peri-implant osteolysis to the quality of life of patients undergoing lumbar or posterolateral lumbosacral arthrodesis in the follow-up period up to 360 days. The quality of life in postoperative has significantly improvement when compared to the preoperative period.

RESUMO Objetivo: Avaliar se a presença de osteólise em torno dos parafusos pediculares influencia a qualidade de vida de pacientes submetidos à artrodese posterolateral da coluna lombossacral. Métodos: Estudo retrospectivo com pacientes submetidos à artrodese posterolateral lombar ou lombossacral por doença espinal degenerativa. Foram realizadas tomografias computadorizadas dos segmentos operados em intervalos de 45, 90, 180 e 360 dias de pós-operatório. Nesses exames, foi pesquisado a presença de um halo radiolucente peri-implante, que foi considerado presente quando maior que 1 mm no corte coronal. Concomitantemente à realização dos exames de TC foi aplicado o questionário Oswestry Disability Index (ODI) para avaliar o grau de incapacidade dos pacientes. Resultados: Foram avaliados 38 pacientes e 14 (36,84%) deles apresentavam algum grau de osteólise ao redor de pelo menos um parafuso pedicular ao final do seguimento. Dos 242 parafusos analisados, 27 (11,15%) apresentaram osteólise no corte coronal da TC, sendo a maioria dessas ocorrências no nível mais distal do segmento com artrodese. Não se observou relação da presença dessa osteólise com a qualidade de vida dos pacientes. A qualidade de vida tem melhora significativa quando se compara o resultado pré-operatório com os resultados pós-operatórios nos diversos momentos de aplicação do ODI. Essa melhora no ODI mantém a linearidade de melhora com o passar do tempo. Conclusão: Não há relação da presença da osteólise peri-implante com a qualidade de vida dos pacientes submetidos à artrodese lombar ou lombossacral posterolateral no período de seguimento até os 360 dias. A qualidade de vida pós-operatória tem melhora significativa quando comparada ao momento pré-operatório.

RESUMEN Objetivo: Evaluar si la presencia de osteólisis alrededor de los tornillos pediculares afecta la calidad de vida de los pacientes que fueron sometidos a artrodesis posterolateral de la columna lumbosacra. Métodos: Estudio retrospectivo de pacientes sometidos a artrodesis lumbar posterolateral o lumbosacra debido a enfermedad degenerativa de la columna vertebral. Se realizaron tomografías computarizadas de los segmentos operados en intervalos de 45, 90, 180 y 360 días después de la cirugía. En estas pruebas, fue investigada la presencia de un halo radiotransparente alrededor del implante, que se consideró presente cuando era mayor que 1 mm en corte coronal. Simultáneamente con la realización de las tomografías se aplicó el cuestionario Oswestry Disability Index (ODI) para evaluar el grado de discapacidad de los pacientes. Resultados: Se evaluaron 38 pacientes y 14 (36,84%) de ellos tenían algún grado de osteólisis alrededor de al menos un tornillo pedicular al final del seguimiento. De los 242 tornillos analizados, 27 (11,15%) tenían osteólisis en el corte coronal de la tomografía, estando la mayoría de estas ocurrencias, en el nivel más distal de la artrodesis. No hubo correlación entre la presencia de la osteólisis a la calidad de vida de los pacientes. La calidad de vida ha mejorado de manera significativa al comparar los resultados preoperatorios con los resultados postoperatorios en sus distintos momentos del ODI. Esta mejora en el ODI mantiene linealidad de mejoría con el tiempo. Conclusión: No existe correlación entre la presencia de osteólisis alrededor del implante a la calidad de vida de los pacientes sometidos a artrodesis posterolateral lumbar o lumbosacra en el período de seguimiento de hasta 360 días. La calidad de vida postoperatoria ha mejorado significativamente en comparación con el período preoperatorio.

Factores pronósticos de complicaciones postquirúrgicas en pacientes con infecciones óseas y seudoartrosis / Prognostic factors for post surgical complications in bone infection and pseudarthrosis

Resumen: La infección ósea y la seudoartrosis son las principales complicaciones ortopédicas en cuyo tratamiento intervienen múltiples factores en la tasa de falla al tratar de corregirlas. Conocer estos factores fue el problema que originó la investigación a través de un estudio longitudinal y prospectivo de una cohorte histórica de 83 pacientes de 43.3 ± 16.1 años de edad tratados por seudoartrosis asépticas y sépticas, osteomielitis, osteítis, consolidación viciosa o prótesis infectadas, el desenlace se relacionó con los factores pronósticos sistémicos y locales tomados del modelo de Cierny-Mader como factores que afectan la vigilancia inmunológica, el metabolismo y la vascularización local. Para el análisis bivariado se aplicó χ2 o el test exacto de Fisher; para el análisis multivariado se aplicó el modelo de regresión logística binaria no condicional con método de Wald hacia atrás para seleccionar los factores pronósticos significativos. El error alfa se fijó ≤ 0.05. Las complicaciones se presentaron en 51.8% de los casos. Los factores locales (linfedema, arteritis, insuficiencia venosa y pérdida de piel) con una OR de 5.0 (IC 95% 1.0-24.9, p = 0.03), las seudoartrosis sépticas con OR de 5.0 (IC 95% 1.9-13.0, p = 0.001) y fracturas segmentarias con OR de 3.2 (IC 95% 0.8-13.0, p = 0.07) fueron los factores pronósticos identificados en el análisis bivariado; sin embargo, la regresión logística sólo seleccionó como factor significativo a las seudoartrosis sépticas. Es necesario detectar y en su caso controlar o eliminar dichos factores que pueden incidir directamente en malos resultados postquirúrgicos.

Abstract: Bone infection and nonunion are the main orthopedic and traumatic complications whose treatment remains a challenge because multiple factors are involved in the rate of failures when you try to correct them. Knowing these factors were the problem that caused the research through a prospective longitudinal study of 83 patients of 43.3 ± 16.1 years old. They were treated for aseptic and septic nonunion, osteomyelitis, osteitis, malunion or infected joint replacement. The cases were classified with or without postoperative complications and outcome related to systemic and local factors taken prognostic model Cierny-Mader as factors affecting immune surveillance, metabolism and local vascularization. For bivariate analysis of data χ2 it was applied or where appropriate Fisher's exact test; for multivariate analysis model not conditional binary logistic regression method was applied Wald backward to select the significant prognostic factors. The alpha error was set ≤ 0.05. General complications occurred in 51.8% of cases. Local factors (lymphedema, arteritis, venous insufficiency, loss of skin) with an OR of 5.0 (95% CI 1.0-24.9, p = 0.03), septic nonunion with OR of 5.0 (95% CI 1.9-13.0, p = 0.001) and segmental fractures with an OR of 3.2 (95% CI 0.8-13.0, p = 0.07) were the prognostic factors identified in the bivariate analysis; however, the logistic regression only selected as the septic pseudoarthrosis as a significant factor. It is necessary to detect and if necessary control or eliminate those factors that can directly affect poor postoperative results.

Valores de vitamina D en fracturas no consolidadas / Vitamin D levels in non-union fractures

Introducción: La falta de consolidacion de una fractura es, en general, un fenomeno multifactorial. El objetivo de este estudio fue estimar los valores de referencia de vitamina D (25OHD3) en fracturas que no consolidaron, estudiar su asociacion con la edad y su localizacion. Materiales y Métodos: Estudio prospectivo, de observacion y descriptivo en 29 pacientes con fracturas no consolidadas. Se determinaron las concentraciones sericas de vitamina D (25OHD3) junto con los estudios prequirurgicos. Se calcularon modelos generalizados para estimar los efectos de la edad y la localizacion, y detectar grupos de pacientes con niveles inferiores al valor recomendado. Resultados: El 68,9% de los pacientes tenia concentraciones sericas promedio de vitamina D inferiores al valor normal (30,0 ng/ml), que se asociaron inversamente con la edad, 40 anos fue el punto de corte a partir del cual otras caracteristicas, como la localizacion de la fractura (en huesos que afectan a los miembros inferiores), condicionan conjuntamente la falta de consolidacion. Conclusiones: La mayoria de los pacientes cuya fractura no consolido tenia deficiencia de vitamina D y este fenomeno es marcado a partir de los 40 anos de edad. Es importante identificar a los pacientes con mayor riesgo de presentar este deficit en las primeras etapas del tratamiento de las fracturas, ya que el aporte de este micronutriente es un factor reconocido para disminuir el riesgo de falta de consolidacion. Nivel de Evidencia: IV

Introduction: Absence of bone union after a fracture is generally multifactorial phenomenon. The objective of this study was to determine reference vitamin D values (25OHD3) in non-unions, and to study their association with age and localization. Methods: A prospective, observational and descriptive study was performed to evaluate 29 patients with non-union fractures. Serum vitamin D levels (25OHD3) were determined together with standard preoperative studies. Generalized models were used to estimate the effects of age and location, as well as to detect the group of patients with vitamin D levels lower than recommended. Results: The 68.9% had serum levels of vitamin-D lower than the normal value (30 ng/mL), which was inversely associated with age, being the age of 40 the cutoff point from which other characteristics, such as location, conditioned simultaneously the non-union. Conclusions: Most patients with a non-union fracture had vitamin D deficiency, and this phenomenon was more evident in patients >40 years. Prompt identification of patients with increased risk of presenting this deficiency is important, as treatment could reduce the incidence of fractures that evolve into a non-union. Level of Evidence: IV

Bilateral congenital seudarthrosis of the clavicle. A clinical case. / Seudoartrosis congénita de clavícula bilateral. Caso clínico.

Congenital pseudarthrosis of the clavicle is a rare malformation in which the aetiology is still unclear. Bilateral involvement is exceptional. Although it is a congenital malformation, it may not be diagnosed until late childhood, with patients presenting with a painless deformity of the middle third of the clavicle in the absence of prior trauma. The treatment is controversial, and may be surgical, depending on the functional impact and aesthetics. A case of bilateral involvement is presented, together with a review of the relevant literature.

Salvataje de fracturas laterales de cadera con clavo-placa de 95º (AO/ASIF) / Lateral hip fracture salvage with 95º blade plate (AO/ASIF)

Introducción: Con las técnicas contemporáneas de reducción y osteosíntesis, la mayoría de las fracturas intertrocantéricas de cadera y de cuello femoral suelen consolidar sin problemas. La mayoría de estas fracturas se tratan mediante reducción cerrada y fijación interna con excelentes resultados. El fracaso terapéutico, por lo general, conduce a dolor y discapacidad funcional. En estos casos, los posibles tratamientos se reducen a dos, si se exceptúa el manejo conservador para pacientes críticos, una opción es una nueva osteosíntesis o la artroplastia total de cadera. La valguización de la falla de las fracturas tiene como objetivo transformar las fuerzas de cizallamiento de la zona de seudoartrosis en fuerzas compresivas, estimulando así la consolidación de las fracturas. Materiales y Métodos: Se evaluó retrospectivamente a 14 pacientes con seudoartrosis de fracturas intertrocantéricas de cadera, entre enero de 2010 y febrero de 2014, operados en nuestra institución. Todos fueron sometidos a una revisión con el objetivo de lograr una posición en valgo del fragmento proximal fijado siempre con clavo-placa de 95º (AO/ASIF). El objetivo de este estudio fue evaluar los resultados clínicos y radiológicos de seudoartrosis de fracturas intertrocantéricas de cadera. Resultados: Se logró la consolidación de la fractura en los 14 pacientes. El tiempo de consolidación promedio varió de tres a seis meses. El puntaje de Harris promedio para la valoración subjetiva fue de 82,65. En ningún caso, se extrajo el material luego de la consolidación de la fractura. Conclusión: El clavo-placa de 95º (AO/ASIF) sigue siendo una muy buena opción en los casos de seudoartrosis de fémur proximal, siempre que la planificación preoperatoria y la técnica quirúrgica sean correctas, y el posoperatorio sea adecuado.

Introduction: Contemporary techniques for reduction and internal fixation make most femoral neck and intertrochanteric hip fractures heal without problems. Most of these fractures are treated with closed reduction and internal fixation achieving excellent results. Treatment failure of hip fractures usually leads to pain and disability. Therapeutic alternatives can be limited to two options, with the exception of the conservative non-operative treatment in critical patients: a new fixation system or an arthroplasty. The valgus osteotomy aims to transform the shear forces in the area of nonunion into compressive forces, thereby stimulating fracture healing. Methods: Fourteen patients with intertrochanteric hip fracture nonunion were retrospectively evaluated between January 2010 and February 2014. All patients underwent revision surgery in order to achieve a valgus position of the proximal fragment, using a 95º blade plate (AO/ASIF). The objective of this study was to evaluate the clinical and radiographic results of intertrochanteric hip fracture nonunion treated with this method. Results: Fracture healing was achieved in all 14 patients. Average healing time ranged from three to six months. The Harris score averaged 82.65. Hardware removal was not performed after fracture healing. Conclusion: The 95° blade plate is still a very good option in cases of proximal femur nonunion, provided the preoperative planning and the surgical technique are correct and the postoperative care is adequate.
