Total hip arthroplasty is a successful procedure with high rates of functional satisfaction and pain relief. A large number of patients with bilateral hip pathology will require both hip joint replacement, from there born the inquietude to knowing benefits and disadvantage of bilateral simultaneous hip arthroplasty. We present a female patient case who developed bilateral hip osteoarthritis secondary to development dysplasia of the hip which was surgically managed with bilateral arthroplasty at one time. We show a follow-up report of the case and a review of the literature to know the main advantages of this new current of hip arthroplasty in patients with bilateral hip pathology

Introducción El propósito de este estudio es determinar si los pacientes con artrosis severa intervenidos con artroplastia de rodilla o cadera ponen en riesgo su expectativa de vida. Método Se diseñó un estudio de sobrevida el cual fue aprobado por el comité de ética de nuestra institución. Los pacientes fueron incluidos si fueron intervenidos de artroplastia de rodilla y cadera por artrosis severa y tenían más de 50 años. Los pacientes fueron excluidos si la artroplastia se realizó por fractura, hemofilia o un tumor. Una regresión multiparamétrica de Weibull fue estimada, siendo reportado el hazard ratio. Un bootstrap de 200 repeticiones fue realizada para validación interna. Resultados Un total de 4094 artroplastias fueron incluidos. La curva de Kaplan-Meier estima una mayor sobrevida que la población general hasta los 12 años, luego de lo cual la mediana de sobrevida es menor que la de la población general. La regresión multiparamétrica de Weibull estimó hazard ratios de 1,53 (intervalo de confianza 95%: 1,27 a 1,84) en mujeres, de 1,09 (1,08 a 1,10) por cada año de edad y de 1,29 (1,07 a 1,53) en artroplastia de cadera. Conclusión La mortalidad después de una intervención de artroplastia de rodilla o cadera sigue un comportamiento bimodal respecto a la población general similar a series reportadas en Estados Unidos y Suecia. Inicialmente la sobrevida es mayor que la población general, pero es menor luego de 12 a 15 años.

Background The purpose of this study is to determine if patients with osteoarthritis that undergo hip or knee arthroplasty jeopardize their life expectancy in Chile. Methods A survival analysis study was designed and approved by our institutional ethics review board. Patients were included if they underwent surgery for hip or knee osteoarthritis and were 50 years or older at the time of surgery. Patients were excluded if arthroplasty was performed for fracture, hemophilia arthropathy, or tumor. A multiparametric Weibull regression was estimated, and the hazard ratio was reported. For internal validity, a bootstrap of 200 repetitions was performed. Results A total of 4 094 arthroplasties were included. The Kaplan-Meier curve estimates a higher survival than the general population up to 12 years, after which the median survival is less than the general population. The bootstrap multiparametric Weibull regression estimated a hazard ratio of 1.53 (95% confidence interval: 1.27 to 1.84) for women, 1.09 (1.08 to 1.10) for every year older, and 1.29 (1.07 to 1.53) for hip arthroplasty patients. Conclusion Mortality after hip and knee arthroplasty in Chile follows a bimodal behavior similar to reports from the United States and Europe. At first, mortality is lower than the general population but worsens after 12 to 15 years of surgery.

OBJECTIVE@#Severe hip osteoarthritis, caused by bone or joint maldevelopment, biomechanical transformation and previous surgical intervention, is inclusively existed in spondyloepiphyseal dysplasia (SED). To investigate and discuss the short-term efficacy and possible effects of total hip arthroplasty in the treatment of Tönnis grade 3 hip osteoarthritis in patients with SED.@*METHODS@#From January 2017 to June 2019, 374 patients with hip osteoarthritis were involved for total hip arthroplasty conducted by senior professional surgeons, of whom 9 patients (6 males and 3 females) with 12 hip osteoarthritis secondary to the SED met the inclusive and exclusive criteria and received the above-mentioned hip operation. The short-term outcomes were observed.@*RESULTS@#All the patients were implanted with Johnson & Johnson ceramic on ceramic cementless hip prostheses within the arthroplasty. They were followed up for an average period of 20 months. Except for one muscular calf vein thrombosis case, no complications, such as aseptic loosening, joint dislocation, fracture, neurovascular injury, deep vein thrombosis and infection were observed in all the 9 patients. Before the surgery, the average Harris hip score was 35.55, while the average of the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) was 56.56. The level of quality of life indicated by SF-12 score was 41.56 on average. The mean pre-operation visual analogue scale (VAS) was 7.44. At the last follow-up, the average Harris hip score increased to 89.56, whereas the average WOMAC declined to 41.11. Compared with the baseline point, the average SF-12 score went up to 56.33. Dramatic drop of the mean VAS value to 2.67 was also observed at the last follow-up. In addition, post-operative increase of several pelvic-related parameters including pelvic incidence, pelvic tilt and sacral slope could be observed in the SED patients. The average measured pelvic incidence, pelvic tilt and sacral slope were 68.95°±4.60°, 52.75°±1.06° and 17.45°±1.77° before operation, respectively; whilst the mean value of these specific parameters increased to 76.98°±5.12°, 60.51°±4.35° and 18.10°±2.02°, respectively. The even leg lengths of the lower extremities were obtained after total hip arthroplasty.@*CONCLUSION@#Total hip arthroplasty is satisfactory in the short-term pain relieve and function recovery for the management of Tönnis grade 3 hip osteoarthritis secondary to the SED.

ABSTRACT Objectives: compare an accelerated physiotherapeutic protocol to a conventional physiotherapeutic protocol in total hip arthroplasty patients. Methods: a randomized double blinded clinical trial performed from August 2013 to November 2014. Forty-eight patients diagnosed with hip osteoarthritis submitted to a total hip arthroplasty surgery. An accelerated rehabilitation physiotherapy applied three times a day and start gait training on the first day or standard physiotherapy applied once a day and start gait training on the second or third day of hospitalization. The Merle dAubigné and Postel score (mobility, pain and gait), muscle strength force, range of motion, in hospital stay and time to start of gait training, were the outcomes. Results: the mean age was 64.46 years (10.37 years standard deviation). No differences were observed in age in different genders, and the two randomization groups were homogeneous. In hospital stay was lower in the intervention group compared to the control group, 3 (3-4) days [median (interquartile range)] versus 4 (4-5) days. Time to the start of gait training was early in the intervention group compared to the control group, 1 (1-1) days versus 2 (2-2) days. Higher muscle strength values were observed in the postoperative results in the intervention group compared to the control group for internal rotation, external rotation and abduction. Conclusions: an accelerated physiotherapeutic protocol should be encouraged, because it shows favourable results in gait, muscle strength and length of hospital stay, even upon hospital discharge.

RESUMO Objetivos: comparar um protocolo fisioterapêutico acelerado com um protocolo fisioterapêutico convencional em pacientes submetidos a artroplastia total do quadril. Métodos: ensaio clínico randomizado, duplo-cego, realizado de agosto/2013 a novembro/2014. Quarenta e oito pacientes diagnosticados com coxartrose submetidos a cirurgia de artroplastia total do quadril. Fisioterapia de reabilitação acelerada aplicada três vezes ao dia com início de marcha no primeiro dia ou fisioterapia convencional aplicada uma vez ao dia e início de marcha no segundo ou terceiro dia de hospitalização. Os escores de Merle dAubigné e Postel (mobilidade, dor e marcha), força muscular, amplitude de movimento, internação hospitalar e tempo para o início de marcha foram os desfechos. Resultados: a idade média foi 64,46 anos (desvio padrão 10,37 anos). Não foram observadas diferenças na idade nos diferentes sexos, e os grupos de randomização foram homogêneos. O tempo de internação hospitalar foi menor no grupo intervenção em comparação ao grupo controle, 3 (3-4) dias [mediana (intervalo interquartil)] versus 4 (4-5) dias. O tempo para início da marcha foi precoce no grupo de intervenção em comparação ao grupo controle, 1 (1-1) dias versus 2 (2-2) dias. Maiores valores de força muscular foram observados nos resultados pós-operatórios no grupo intervenção em comparação ao grupo controle para rotação interna, rotação externa e abdução. Conclusões: um protocolo fisioterapêutico acelerado deve ser incentivado, pois apresenta resultados favoráveis na marcha, força muscular e tempo de internação, mesmo após a alta hospitalar.

Objetivo: Determinar los resultados clínicos, la supervivencia y la incidencia de fractura periprotésica intraoperatoria con un tallo corto tipo 2B de fijación cervicometafisaria. Materiales y Métodos: Se analizaron prospectivamente los primeros 100 tallos (84 pacientes) MiniHipTM (Corin, Cirencester, Reino Unido) colocados, en forma consecutiva, por un mismo cirujano. La edad promedio fue de 47 años. La indicación para un tallo corto fue: edad <55 años (85 casos) o la participación previa en deportes de impacto en pacientes de entre 56 y 60 años (15 casos). El diagnóstico inicial fue artrosis primaria de cadera en el 82% de los casos. El seguimiento promedio fue de 42 meses. Resultados: El puntaje en la escala de Harris modificada mejoró de 55 a 96 al final del seguimiento (p = 0,02) y ningún paciente refirió dolor de muslo en el posoperatorio. La supervivencia del tallo fue del 99% (IC95% 93,1-99,8). Un caso presentó una perforación de la cortical lateral intraoperatoria, tratado con revisión con un tallo no cementado convencional. Un paciente tuvo una infección aguda, que fue tratada con desbridamiento, retención de componentes y antibióticos, con resultado favorable a los 48 meses de la cirugía. Se produjeron 3 fracturas incompletas del calcar intraoperatorias (3%). Conclusiones: Se obtuvieron resultados excelentes en esta serie de pacientes jóvenes y activos operados por un mismo cirujano con un tallo corto tipo 2B, a los 2-5 años de seguimiento, con un 1% de falla por falsa vía femoral intraoperatoria. Nivel de Evidencia: IV

Objective: We aimed to determine 2- to 5-year survivorship rate, intraoperative fractures, subsidence and thigh pain rate in a consecutive, independent, one-surgeon series of surgical patients in whom a type 2B short stem was implanted. Methods: We reviewed the first 100 type 2B consecutive femoral short stems implanted in 84 patients with a mean age of 47 years old. Indications included age younger than 55 years (85 hips), or participation in impact sports in patients aging 56 to 60 years old (15 hips). Initial diagnosis was osteoarthritis in 82% of the cases. Median follow-up was 42 months. Results: Stem survivorship rate was 99% at 2 to 5 years followed by stem revision for any aseptic reason, and 98% when infection played a part. Mean Harris Hip Score improved significantly from 55 to 96 at final follow-up (p 0.02). There was one lateral cortex perforation, and three intra-operative calcar partial fractures (3%), only one of them required cerclage wiring and delayed weight-bearing. No patient referred thigh pain at final follow-up. Only one case subsided 4 mm, but then stabilized. The risk of revision was 1% after 2 to 5 years (95%CI 93.1-99.8%). Conclusions: We obtained promising short-term results with this device in this single-surgeon, non-consecutive series -including the learning curve period- using a type 2B short stem in young active patients-, in which bone preservation is warranted. Level of Evidence: IV

INTRODUÇÃO: A Artoplastia de Quadril (AQ) é um procedimento cirúrgico realizado em casos de fratura de colo do fêmur (FF) e osteoartrose de quadril (OQ), e é responsável por causar danos funcionais aumentando o nível de dependência funcional do idivíduo idoso. OBJETIVO: analisar o nível de dependênciaonentre idosos que foram submetidos a AQ. MÉTODOS: indivíduos idosos internados na enfermaria traumato-ortopédica do Hospital Universitário da Universidade Federal do Maranhão (HU-UFMA) foram avaliados quanto ao seu nível de dependência funcional através da Medida de Independência Funcional (MIF) e quanto ao nível de dor por meio da Escala Visual Analógica (EVA), tanto no pré quanto no pós-operatório de AQ. Os voluntários foram divididos em grupo A, com diagnóstico de (OQ), e grupo B, com diagnóstico de (FF). O teste t não pareado foi utilizado para comparar os resultados no pré e pós-operatório, adotando-se nível de significância p<0,05. RESULTADOS: um total de 46 idosos compuseram a amostra, 17 (37%) do sexo masculino e 29 (63%) do sexo feminino. O grupo A apresentou menor nível de dependência funcional no pré-operatório em comparação aos sujeitos do grupo B, porém, a avaliação da dor revelou índices maiores para o grupo A no pré-operatório. A análise comparativa dos resultados da EVA no pré e pós-operatório se mostrou estatisticamente significante para ambos os grupos. Os resultados da MIF para o grupo A não foram estatisticamente significantes, para o grupo B, porém, os domínios autocuidados, mobilidade, locomoção e total apresentaram valores estatisticamente significantes. CONCLUSÃO: O grupo A apresentou maiores médias na EVA no pré-operatório e menor nível de dependência funcional pela MIF em comparação ao grupo B, este apresentou as maiores médias de idade e maior presença de co-morbidades.

INTRODUCTION: Hip Arthroplasty (HA) is a surgical procedure performed in cases of femoral neck fracture (FF) and hip osteoarthrosis (HO), and is responsible for causing functional damage by increasing the level of functional dependence of the elderly individual. OBJECTIVE: analyze the level of functional dependence among elderly patients who underwent AQ. METHODS: elderly subjects hospitalized at the trauma-orthopedic ward of the University Hospital of the Federal University of Maranhão (HU-UFMA) were evaluated for their level of functional dependence through the Functional Independence Measure (FIM) and the level of pain through Visual Analogue Scale (VAS), both in the pre and postoperative periods. The volunteers were divided into group A, with diagnosis of hip osteoarthrosis, and group B, with diagnosis of femoral neck fracture. The unpaired t test was used to compare the results in the pre and postoperative period, adopting a significance level of p <0.05. RESULTS: A total of 46 elderly individuals comprised the sample, 17 (37%) males and 29 (63%) females, group A presented a lower level of functional dependence in the preoperative period compared to the subjects in group B, however, the evaluation of pain revealed larger indices for group A in the preoperative period. The comparative analysis of the VAS results in the pre and postoperative periods was statistically significant for both groups. The FIM results for group A were not statistically significant for group B, but the self-care domains, mobility, locomotion and total domains presented statistically significant values. CONCLUSION: Group A had higher mean values in the preoperative VAS and lower level of functional dependence for the FIM compared to group B, which had the highest mean age and greater presence of comorbidities.

RESUMO Objetivo: comparar dados clínicos, laboratoriais e densitométricos de pacientes com osteoartrose e com fratura do colo femoral. Métodos: estudo transversal de pacientes com fratura do colo femoral e osteoartrose do quadril, submetidos à artroplastia de quadril. Dados clínicos, laboratoriais e densitométricos foram coletados. Resultados: cinquenta e três pacientes foram incluídos, 22 com fraturas do colo femoral e 31 com osteoartrose. Pacientes com fratura do colo do fêmur apresentaram maior idade do que os pacientes com osteoartrose, tendo valores de IMC, densidade mineral óssea e força de preensão palmar (pacientes sarcopênicos) inferiores, estando mais incapacitados neurologicamente e apresentando um pior escore ASA. Entre os vários parâmetros bioquímicos analisados, diferenças estatisticamente significantes foram encontrados no cálcio sérico total, cálcio ionizado, vitamina D, tiroxina livre, eritrócitos, hemoglobina, hematócrito, glóbulos brancos totais, neutrófilos, linfócitos e creatinina entre os dois grupos. Outros hormônios analisados e parâmetros bioquímicos não diferiram significativamente, apesar de mostrarem tendências entre os dois grupos. Conclusão: pacientes com fraturas do colo do fêmur são mais idosos do que pacientes com osteoartrose, apresentam um menor peso e IMC, são mais debilitados, muitos com anemia e massa óssea reduzida, além de terem uma diminuição significativa no cálcio total, cálcio ionizado, vitamina D e creatinina e um aumento significativo na tiroxina livre.

ABSTRACT Objective: to compare clinical, laboratory and densitometric data from patients with osteoarthrosis and femoral neck fractures. Methods: we conducted a cross-sectional study of patients with femoral neck fracture and hip osteoarthrosis submitted to hip arthroplasty. We collected clinical, laboratory and densitometric data. Results: we included 53 patients, 22 with femoral neck fractures and 31 with osteoarthrosis. Patients with femoral neck fractures were older than patients with osteoarthrosis, with lower BMI values, bone mineral density and palmar grip strength (sarcopenic patients), being more neurologically impaired and presenting a worse ASA score. Among the various biochemical parameters analyzed, we found statistically significant differences in total serum calcium, ionized calcium, vitamin D, free thyroxine, erythrocytes, hemoglobin, hematocrit, total white blood cells, neutrophils, lymphocytes and creatinine between the two groups. Other hormones analyzed and biochemical parameters did not differ significantly, although they showed trends between the two groups. Conclusion: patients with femoral neck fractures are older than patients with osteoarthrosis, have a lower weight and BMI, are more debilitated, many with anemia and reduced bone mass, and have a significant decrease in total calcium, ionized calcium, vitamin D and creatinine and a significant increase in free thyroxine.

Total hip arthroplasty in the young leads to difficult choices in implant selection. Until recently bone conserving options were not available for younger patients with deficient femoral head bone stock. The novel Birmingham Mid-Head Resection (BMHR) device offers the option of bone conserving arthroplasty in spite of deficient femoral head bone stock. Femoral neck fracture is a known complication of standard resurfacing arthroplasty and is the most common reason for revision. It is unknown whether this remains to be the case for the BMHR neck preserving implants. We report a case of a 57-year-old male, who sustained a periprosthetic fracture following surgery with a BMHR arthroplasty. This paper illustrates the first reported case of a BMHR periprosthetic fracture. The fracture pattern is spiral in nature and reaches to the subtrochanteric area. This fracture pattern is different from published cadaveric studies, and clinicians using this implant should be aware of this as revision is likely to require a distally fitting, rather than a metaphyseal fitting stem. We have illustrated the surgical technique to manage this rare complication.

Introducción: En este estudio multicéntrico (Hospital de Cabueñes y Hospital Universitario Santa Lucía) se evalúan los resultados de una serie retrospectiva y continua de 135 PTC realizadas implantando un cotilo doble movilidad de nueva generación. Material y métodos: Se estudiaron 135 PTC intervenidas entre 2005 y 2008. El seguimiento medio fue de 32 meses. Las causas de la cirugía fueron 31.8% coxartrosis y 68.1% fracturas de cadera. La edad media era de 82.1 años. Todos los pacientes eran revisados periódicamente haciendo una valoración clínica y radiográfica. Resultados: El seguimiento pudo ser realizado durante más de 24 meses en 121 PTC (14 pacientes fallecidos). En la última revisión, mayo 2011: 119 cótilos no presentaban aflojamiento. Las complicaciones fueron: 2 luxaciones postquirúrgicas; 4 TVP; 3 infecciones PTH; 5 fracturas peri PTC; 2 aflojamientos cetilo y 1 hundimiento vástago. HHS preoperatorio medio: 45, 83 y postoperatorio medio: 80, 03. De los 135 cotilos revisados sólo dos presentaban modificaciones radiográficas sin signos clínicos. La supervivencia aislada del cótilo a los 12 meses fue 97.03% (87.3-99.2) con un intervalo de confianza del 95% y a los 5 años, un 96.7% (85.4-98.8). Discusión: En nuestro estudio el nuevo cótilo doble movilidad ha mostrado buenos resultados en las siguientes indicaciones: coxartrosis primaria y fracturas de cuello de fémur. Conclusión: Las complicaciones obtenidas en esta serie aparecen en el mismo porcentaje que en otras series de la literatura excepto para la luxación. En ésta, el porcentaje (1.48%) era mucho más pequeño que el de las series clásicas, especialmente en los pacientes con problemas neuromusculares o cognitivos (un tercio de los pacientes).

Introduction: This multi-center study (Cabueñes Hospital and Santa Lucía University Hospital) assessed the results of a retrospective and ongoing series of 135 total hip arthroplasties (THA) in which a latest generation dual-mobility cup was implanted. Material and methods: A total of 135 THAs performed between 2005 and 2008 were analyzed. Mean follow-up was 32 months. The causes of surgery were: coxarthrosis in 31.8% and hip fracture in 68.1%. Mean age was 82.1 years. All patients were seen at regular follow-up visits for clinical and radiological assessments. Results: The follow-up lasted over 24 months in 121 THAs (14 patients died). In the most recent follow-up, in May 2011, 119 cups did not show any loosening. Complications were as follows: 2 postoperative dislocations; 4 DVTs; 3 infections; 5 periprosthetic fractures; 2 loosened cups, and one subsided stem. The mean preoperative Harris Hip Score (HHS) was 45, 83; the mean postoperative HHS was 80, 03. Only two of the 135 cups analyzed had radiographic modifications without clinical signs. Isolated cup survival at 12 months was 97.03% (87.3-99.2) with a 95% confidence interval; survival at 5 years was 96.7% (85.4-98.8). Discussion: In our study, the new dual-mobility cup showed good results for the following indications: primary coxarthrosis and femur neck fractures. Conclusion: The complication rate in our series was similar to the one reported in other series in the literature, except for dislocation. The latter was considerably less frequent (1.48%) in our series compared to the rates reported by the classical series, especially in patients with neuromuscular or cognitive problems (one third of patients).

Zoledronic acid has been used for prevention of osteolytic and osteoblastic bone metastasis. This case report illustrates an undesirable consequence from prolonged usage of zoledronic acid in bone metastasis prevention. Periprosthetic acetabular fracture in a patient treated with zoledronic acid for 7 years was reported. The clinical presentation, radiographic and pathological results were described. This is a rare complication after total hip arthroplasty which should not be ignored especially in patients who received long term bisphosphonate.

Introducción: La superficie cerámica-cerámica causa complicaciones, como la fractura y la generación de ruidos articulares (squeaking). Este estudio muestra nuestra experiencia con la utilización del compuesto de matriz alúmina (cerámica Delta). Materiales y Métodos: Se evaluaron, en forma retrospectiva, 109 caderas, 97 pacientes, con edad promedio de 49 años (rango 17-77). Ciento dos de estas caderas fueron cirugías primarias, mientras que 7 fueron revisiones. Todos los componentes acetabulares fueron Pinnacle® (DePuy Orthopaedics, Warsaw, Indiana, EE.UU). La cerámica utilizada en todos los casos fue Biolox® Delta (Ceram Tec AG, Plochingen, Alemania). Resultados: El seguimiento fue de 37 meses (rango 24-50). Se realizó la medición radiográfica de la anteversión, por el método de Ackland (rango 1°-35°), la inclinación (rango 22°-67°), el diámetro acetabular (rango 48-62 mm), el tamaño de la cabeza femoral (88: 36 mm y 21: 28 mm) y la lateralización antes de la cirugía y después de ella. Se evaluó a todos los pacientes con el puntaje de Harris, los resultados fueron, en su mayoría, muy buenos y algunos, buenos. Las complicaciones fueron: una luxación (0,91%), una subluxación protésica (0,91%), una infección aguda (0,91%), una fractura periprotésica (0,91%), una rotura del inserto de cerámica (0,91%). Ningún paciente refirió ruidos o una cadera chirriante. Conclusión: En esta serie, no se reportaron episodios de chirridos, pese a la gran variación en la anteversión y la inclinación del componente acetabular. Creemos que la composición y el diseño de la cerámica de tercera generación determinarían un menor índice de chirridos que las de segunda generación.

Background: Squeaking is the most frequently related complication with ceramic on ceramic total hip arthroplasty. Third generation Delta ceramics present improved mechanical properties and so far squeaking has not been reported with this bearing surface. The aim of this study was to analyze the incidence of squeaking with the use of third-generation ceramics. Methods: This study included 109 hips in 97 patients, with an average age of 49 years (range 17-77 years), an average body mass index of 22.3 (range 19-48). One hundred and two hips were primary total hip arthroplasties, whereas 7 were revisions. Femoral and acetabular components were Pinnacle® (DePuy Orthopaedics, Warsaw, Indiana, USA). The ceramic used was Biolox® Delta (Ceram Tec AG, Plochingen, Germany) in all the cases. Results: Average follow-up was 37 months (range 24-50 months). Radiographic assessment of the anteversion was made with the Ackland method (range 1°-35°). Inclination (range 22°-67°), acetabulum diameter (range 48-62), size of the femoral head (88 = 36 mm and 21 = 28 mm) and pre- and post-operative offset were also evaluated. We observed 2 dislocations, 1 acute superficial infection, 1 periprosthetic fracture and 1 fracture of the ceramic acetabular insert due to incomplete seating of the acetabular liner. No patient referred noise or a squeaking hip. Conclusion: In this series, squeaking was not observed although the range of anteversion and inclination of the cups was widely variable. Due to its composition and design Delta Ceramic components may have a lower rate of squeaking than second-generation ceramics.

Introducción: El objetivo del presente trabajo es reportar los resultados clínicos y radiológicos iniciales de una serie consecutiva de pacientes selectos tratados en nuestra institución con un único diseño de artroplastia de superficie, comparando además la tasa de revisión temprana con un grupo control de pacientes tratados en el mismo lapso con una artroplastia total de cadera no cementada. Materiales y Métodos: Cuarenta y siete pacientes de sexo masculino (49 caderas) con diagnóstico de artrosis de cadera que fueron tratados quirúrgicamente con una artroplastia híbrida de superficie, entre noviembre de 2006 y julio de 2009. La edad promedio fue de 44,5 años (rango de 21 a 57). En todos los casos, la indicación de la artroplastia de superficie se realizó en pacientes jóvenes con alta expectativa funcional y siguiendo estrictos criterios de selección radiológicos. Se efectuó un seguimiento clínico y un meticuloso análisis radiológico. Resultados: La escala funcional posoperatoria de Merle D'Aubigné-Postel fue, en promedio, de 17,3 puntos a los 43 meses de seguimiento promedio (rango 24-62 meses). El 85 por ciento de los pacientes refirió que practicaba alguna actividad deportiva con una escala UCLA promedio de 9,5 (rango 8-10). Un paciente requirió una cirugía de revisión (2,04 por ciento) por fractura de cuello femoral. No existieron diferencias estadísticamente significativas en cuanto a la tasa de revisión temprana comparando con el grupo control (p = 0,55). Conclusiones: En nuestra experiencia inicial con artroplastia de superficie, obtuvimos resultados a corto plazo favorables, en una serie de hombres con artrosis y alta demanda funcional, estrictamente seleccionados.

Background: The purpose of this study was to analyze the initial clinical and radiological results of a consecutive series of selected patients treated in our institution with the same design of resurfacing total hip arthroplasty. We also compared the rate of initial revision surgery with a similar age group who underwent a non-cemented total hip arthroplasty with hard bearings. Methods: Between November 2006 and July 2009, 49 Durom hip resurfacing were performed at our institution in 47 consecutive patients (2 staged bilateral). All patients were men with osteoarthritis; median age 44.5 years old (range 21 to 55). The resurfacing procedure was indicated in young or very active patients with high sports expectation after surgery and following the Schmalzried radiological selection criteria. We performed a clinical and a meticulous digital radiographic analysis in all patients. Results: Postoperative Merle D'Aubigné-Postel score averaged 17.3 points at 43 months of follow-up (range 24 to 62 months). 85% of the patients performed sports activities with an averaged UCLA test 9.5 (range 8-10). One patient (2.04%) underwent a revision femoral component at 15 months of follow-up due to late, non-traumatic femoral neck fracture. The rate of revision in both groups was similar (p = 0.55). Conclusions: Favorable initial clinical and radiological results can be achieved with the use of hip resurfacing system in properly selected young active patients.

BACKGROUND: In primary total hip replacements (THRs), the dissected femoral heads (FHs) are commonly used to make the bone-chips for the reconstruction in the orthopaedic surgery. The donated FHs are routinely microbiologically cultured to identify and contaminated FHs are discarded. This study examines whether a positive FH culture predicts an infection and prosthetic failure after primary THR. METHODS: The study sampled 274 donated FHs from patients with osteonecrosis (ON), hip joint osteoarthritis (OA), and femoral neck fracture (FNF) in THR to culture the microbes. The FH contamination rates were analyzed for ON, OA, and FNF groups. Proportion of the postoperative infection or prosthetic failure in the group of donors with a positive FH culture were compared to the proportion in the group of donors with a negative FH culture. RESULTS: The rates of the positive culture in the ON, OA, and FNF groups were 7.1%, 3.8%, and 4.0%, respectively. The infection rate was found to be non-significantly greater in the ON group than in the OA and FNF groups. In the negative culture group, one patient (0.63%) had a postoperative superficial infection, and five patients (3.2%) experienced additional surgeries including a fixation for a periprosthetic fracture, within a minimum follow-up of two years. However, no postoperative infection was encountered, and no revision surgery was required in the positive culture group. CONCLUSIONS: A positive FH culture is not always associated with elevated risks of infection or prosthetic failure after THR. Therefore, such finding cannot be used as a prognostic factor of THR. The FHs that return a positive culture may not lead to the orthopaedic assessment of an infection or other postoperative complication risks in primary THR.

Introducción: la displasia de cadera es una causa muy frecuente de artrosis en personas jóvenes. En 1953 el Profesor Karl Chiari describió una osteotomía supracetabular con medialización de la cadera para proveer una mayor cobertura cefálica y aumenta la congruencia articular. Esta osteotomía puede proporcionar una solución en estos pacientes, prolongando y mejorando la función de la cadera. Materiales y Métodos: entre enero de 1973 y diciembre del 2000 se realizaron 45 osteotomías de Chiari en nuestro servicio. Evaluamos retrospectivamente 34 osteotomías en 29 pacientes. Hombres 7, mujeres 22. 33,S años (rango 6 a 59). Seguimiento 15,4 años (rango 8 a 25). Se utilizó score de Barret y score de Harris para la evaluación clínica. Valoración radiológica: ángulo de Wiberg (CEA, centre-edge-angle), índice acetabular (IA), cobertura cefálica(CC), grado de artrosis, ángulo de osteotomía, medialización de la cadera y la clasificación de Severin para evaluar congruencia articular prequirúrgica y posquirúrgica. Se evaluó tiempo de sobrevida de osteotomía y necesidad de artroplastia. Resultados: al último control 11/34 caderas requirieron una artroplastia en promedio 15,9 años luego la osteotomía (rango 4-20). Cuatro caderas fueron excluidas de la valoración funcional por ser en pacientes con parálisis cerebral que no deambulan y 2 por ser en un paciente que falleció. Para las otras 17 caderas el score de Harris promedio de 83,9 puntos, resultados excelentes y buenos en 10/17. El score de Barret mostró 12/17 caderas con excelentes y buenos resultados. No tenían dolor o dolor leve para las actividades de la vida diaria 13/17 pacientes. La osteotomía mejoró el CEA en un promedio 33.8, lA promedio 15.3. La CC mejoró de 60.1 por ciento prequirúrgico a un promedio de 94.4 por ciento. El grado de artrosis evolucionó en 14 pacientes mientras que en 7 se mantuvo igual. Conclusión: la osteotomía de Chiari es un procedimiento efectivo para mejorar y prolongar la función de la articulación de la cadera, a largo plazo, en pacientes jóvenes con displasia sintomática. La artrosis prequirúrgica es un factor pronóstico.

INTRODUÇÃO: A artrite reumatoide (AR) é uma das principais indicações de artroplastia total do quadril (ATQ) ou joelho (ATJ). Estudos internacionais indicam a AR como fator de risco para infecções de prótese. OBJETIVOS: Comparação entre pacientes com AR e osteoartrite (OA) de outras etiologias em relação à incidência de infecções de prótese, infecções incisionais e outras infecções sistêmicas pós-operatórias em ATQ e ATJ. MÉTODOS: Coorte retrospectiva, comparativa, de pacientes acompanhados após a realização de ATQ ou ATJ no Hospital SARAH-Brasília, no período entre 1996 e 2007. RESULTADOS: Setenta e cinco artroplastias em pacientes com AR foram identificadas, das quais 28 ATJ e 47 ATQ. Como controles, foram selecionadas 131 cirurgias em pacientes com OA, das quais 56 ATJ e 75 ATQ, de maneira aleatória e estratificada pela cirurgia e pelo gênero. Não houve diferenças significativas entre os grupos de AR e OA no que diz respeito às taxas de infecções de prótese (respectivamente, ATJ 7,1% vs. 0% e ATQ 2,1% vs. 0%, ambos com P > 0,1), infecção incisional (ATJ 14,3 vs. 3,3% e ATQ 4,3 vs. 1,3%, ambos com P > 0,1) e infecção sistêmica (ATJ 7,1 vs. 3,6%, P = 0,92 e ATQ 4,3 vs. 10,7%, P > 0,1). Após regressão logística múltipla, não houve alteração dos resultados. CONCLUSÕES: A presença de AR não foi identificada como fator de risco para infecções perioperatórias em ATQ e ATJ em casuística do Hospital SARAH-Brasília, em comparação com o grupo de pacientes com OA primária ou secundária a doenças não inflamatórias. A baixa incidência de infecções em ambos os grupos pode explicar os nossos achados.

INTRODUCTION: Rheumatoid arthritis (RA) is one of the major indications of total hip (THA) or knee (TKA) arthroplasty. International studies have suggested that RA is a risk factor for prosthesis infections. OBJECTIVES: To compare patients with RA and patients with osteoarthritis (OA) of other etiologies with regard to the incidence of prosthesis, incisional, and other systemic postoperative infections in THA and TKA. METHODS: Retrospective, comparative cohort of patients followed up after undergoing THA or TKA at the Hospital SARAH-Brasília, from 1996 to 2007. RESULTS: Seventy-five arthroplasties (28 TKA and 47 THA) were identified in RA patients. As controls, 131 surgeries (56 TKA and 75 THA) in OA patients were randomly selected and stratified by surgery and gender. No significant difference was observed between the RA and OA groups regarding the rates of prosthesis infections (TKA 7.1% vs. 0% and THA 2.1% vs. 0%, respectively, both with P > 0.1), incisional infections (TKA 14.3% vs. 3.3% and THA 4.3 vs. 1.3%, respectively, both with P > 0.1), and systemic infections (TKA 7.1% vs. 3.6%, P = 0.92 and THA 4.3% vs. 10.7%, P > 0.1, respectively). After multiple logistic regression, the results did not change. CONCLUSIONS: RA was not identified as a risk factor for perioperative infections in THA and TKA in this case series of the Hospital SARAH-Brasília, as compared with the group of patients with primary OA or OA secondary to non-inflammatory diseases. The low incidence of infections in both groups may explain our findings.

Introducción: El choque femoroacetabular es causa de lesiones del labrum y de coxartrosis en los pacientes jóvenes. Existe escasa evidencia sobre los resultados terapéuticos mediante la osteoplastia coxofemoral por vía anterior sin luxación. El objetivo de este trabajo fue analizar una serie de pacientes tratados con dicha técnica centrándose en los cambios en la calidad de vida. Materiales y métodos: En 22 pacientes con síndrome de tipo cam se realizaron 24 queilectomías y 9 plásticas labrales mediante exposición anterior “reducida”, capsulotomía anterior y osteoplastia insitu. Edad promedio: 44 años; seguimiento promedio: 24 meses. Se documentaron las complicaciones, la amplitud de movimiento y las imágenes radiológicas (Tõnnis). Se definieron los niveles de calidad de vida en pobre, aceptable, buena y muy buena, según el dolor, la escala WOMAC y la reinserción deportiva. Resultados: La amplitud de movimiento aumentó en todos los pacientes. Se comprobó progresión radiológica en 4 casos. Después de 18 meses, 14 permanecían asintomáticos, con calidad de vida muy buena y 3, con buena. Como única complicación se produjo paresia temporal del femorocutáneo en 3 pacientes. Conclusiones: El progreso de la cirugía reconstructiva supone la realización de procedimientos poco agresivos que disminuyan las complicaciones secundarias y permitan una pronta reinserción a las actividades diarias. Esta técnica permite acceder a los osteofitos cervicales y al labrum anterior, donde se localizan 70 por ciento de las lesiones.

Se realizó un estudio observacional descriptivo en 43 caderas intervenidas por artroplastia total no cementada en el Hospital Universitario de Los Andes entre Enero de 2007 y Agosto de 2009, para determinar la correlación existente entre los índices corticodiafisario (ICD), corticometafisario (ICM) y la relación canal-cálcar (CC) preoperatorios con la pérdida ósea periprotésica evaluada mediante densitometría ósea (DEXA) postoperatoria en las zonas de Gruen. Se incluyó igualmente como variable interviniente el uso del ácido zoledrónico en dosis de 5 mg postoperatorios en 24 de los casos para determinar su asociación al aumento de la densidad mineral ósea periprotésica. Se obtuvo correlación entre el índice corticometafisario y la densidad mineral ósea en las zonas 1 y 7 de Gruen, y entre la relación canal-cálcar y la densidad mineral ósea en la zona 2 de Gruen. Por otra parte, el uso del ácido zoledrónico mostró aumento de la densidad mineral ósea en la zona 1 de Gruen.

This is a descriptive observational study of 43 hips which underwent uncemented total arthroplasty at Los Andes University Hospital since January 2007 to August 2009, to determinate correlation among preoperatory corticodiaphysary index (CDI), corticometaphysary index (CMI) and canal to calcar ratio (CCR) with periprosthetic bone loss evaluated through postoperatory bone densitometry (DEXA) in the seven Gruen´s zones. Use of postoperatory 5 mg of zoledronic acid in 24 cases was included as intervening variant to determinate its association with increase in periprosthetic bone mineral density. Correlation was obtained between corticometaphysary index and bone mineral density in Gruen´s zones 1 and 7, and canal to calcar ratio and bone mineral density in Gruen´s zone 2. Besides, it was show increased bone mineral density in Gruen´s zone 1, in patients who received zoledronic acid.

El pinzamiento femoroacetabular es reconocido hoy como una de las principales causas de coxalgia en el adulto joven y corresponde a la primera causa de artrosis la cuarta y sexta década de la vida. El pinzamiento se produce debido a una incongruencia entre el acetábulo y la cabeza femoral; el origen de ésta puede ser principalmente de la porción femoral, tipo CAM, y/o de origen acetabular tipo PINCER. Es un fenómeno dinámico y progresivo en el tiempo, cuyo tratamiento es básicamente quirúrgico, a través de cirugía artroscópica, teniendo como objetivo la restitución de la anatomía normal de la cadera. Los resultados a mediano y largo plazo están en directa relación con el daño articular al momento de la cirugía, teniendo los mejores resultados en pacientes jóvenes y sin artrosis.

Hip impingement syndrome or femoro-acetabular impingement (F Al) is a well known cause of hip pain in the young-adult group, and it is also the main cause of arthritis among people in their forties to sixties. F Al is caused by an offset between the femoral head and acetabulum. This deformity may be mainly present on the femoral side: CAM type, and/or in the acetabular side: PINCER type. It is a dynamic and progressive concern that can be treated with arthroscopic surgery. The main goal of surgery is to restore the normal shape of the hip joint. Mid to long-term results for this procedure depend on age and joint status at the moment of the surgery. Younger, non arthritic patients respond better.
