ABSTRACT

Anterior cruciate ligament (ACL) rupture is a very important epidemiological pathology in our environment. It has a peak incidence between 16 to 39 years of age. It is estimated that between 70-84% of ACL injuries are non-contact. The "no return" position describes the knee in valgus, femoral external rotation, tibial internal rotation and semiflexion, promoting injury to this ligament. Geometric measurements of the knee have been associated with an increased probability of non-contact ACL injury. The management of ACL tears is divided into two: conservative treatment and surgical management. Early OA (osteoarthritis) is the most common consequence of an ACL tear. We present the case of a 35-year-old patient with an inveterate ACL rupture of 10 years of evolution. With conservative management initially that progresses to knee instability and pain in the medial and lateral joint line as well as increased volume and functional limitation. After diagnostic studies, it was decided to perform diagnostic-therapeutic arthroscopy and continued close follow-up for associated pathology.


La ruptura de ligamento cruzado anterior (LCA) es una patología epidemiológicamente muy importante en nuestro medio. Tiene un pico de incidencia entre los 16 a 39 años de edad. Se calcula que entre 70-84% de las lesiones de LCA son sin contacto. La posición de "no retorno" describe a la rodilla en valgo, rotación externa femoral, rotación interna tibial y semiflexión, promoviendo la lesión de este ligamento. Las medidas geométricas de la rodilla se han asociado con un aumento en la probabilidad de lesión del LCA sin contacto. La ruptura crónica del LCA conlleva al desarrollo de artrosis en pacientes jóvenes. El manejo de la ruptura del LCA se divide en dos: tratamiento conservador y manejo quirúrgico. La osteoartrosis temprana es la consecuencia más común de la ruptura del LCA. Presentamos el caso de un paciente de 35 años con ruptura inveterada del LCA de 10 años de evolución. Con manejo conservador inicialmente que progresa a inestabilidad de rodilla y dolor en línea articular medial y lateral, así como aumento de volumen y limitación funcional. Tras estudios diagnósticos, se decide realizar artroscopía diagnóstica-terapéutica y se continúa con seguimiento estrecho por patología asociada.

ABSTRACT

Resumen: Introducción: Las rupturas del manguito de los rotadores (MR) se presentan en más de 50% de los pacientes mayores de 60 años y pueden causar cambios en la biomecánica normal del hombro que pueden desencadenar una artropatía por desgarro del MR. Actualmente, no existe un consenso sobre el tratamiento para el desgarro masivo del MR. Objetivo: Evaluar los resultados clínicos y radiográficos de la colocación del balón subacromial en estas lesiones. Material y métodos: Estudio analítico, longitudinal y retrospectivo de 10 pacientes consecutivos tratados con el uso del balón subacromial. Se utilizaron escalas de Constant (CS) y ASES prequirúrgicas, a los seis y 12 meses de seguimiento postquirúrgico. Los resultados radiográficos fueron valorados por medio del intervalo acromio-humeral (IAH) en una radiografía anteroposterior (AP) verdadera de hombro. Resultados: La mejoría promedio en la CS fue de 41.7 ± 8.93 a los 12 meses de seguimiento, la escala de ASES mostró una mejoría promedio de 64.6 ± 4.9 a los 12 meses de seguimiento. El IAH prequirúrgico fue de 6.1 ± 1.10 y la media a los 12 meses de seguimiento fue de 7.1 ± 0.9. Se observó una mejoría clínica y radiográfica en todas las escalas; sin embargo, no se encontraron resultados estadísticamente significativos. Conclusión: El balón subacromial previene el ascenso de la cabeza humeral en los primeros 12 meses de colocado; suponemos que podría restaurar la cinemática glenohumeral normal mejorando movilidad y disminuyendo dolor.


Abstract: Introduction: Rotator cuff (MR) ruptures occur in more than 50% of patients over the age of 60, and can cause changes in normal shoulder biomechanics that can trigger rotator cuff tear arthropathy. There is currently no consensus on treatment for massive rotator cuff tears. Objective: To evaluate the clinical and radiographic outcomes of subacromial balloon placement in these lesions. Material and methods: Analytical, longitudinal and retrospective study of 10 consecutive patients treated with the use of the subacromial balloon. Constant (CS) and ASES scales were used preoperatively and at 6, 12 months of post-surgical follow-up. Radiographic results were assessed using the Acromio-humeral Interval (AHI) on a true AP shoulder X-ray. Results: The average improvement in CS was 41.7 ± 8.93 at 12 months of follow-up, the ASES scale showed an average improvement of 64.6 ± 4.9 at 12 months of follow-up. The presurgical AHI was 6.1 ± 1.10 and the mean at 12 months of follow-up was 7.1 ± 0.9. Clinical and radiographic improvement was observed at all scales, however no statistically significant results were found. Conclusion: The subacromial balloon prevents the ascent of the humeral head in the first 12 months of placement; we assume that it could restore normal glenohumeral kinematics by improving mobility and decreasing pain.

ABSTRACT

Antecedentes: La necrosis avascular de la cabeza femoral es una patología frecuente en pacientes con antecedentes de trauma, encontrándose como causas patologías vasculares, oncológicas, estados hipercoagulantes, tratamientos esteroideos prolongados, asociándose en algunos casos en pacientes con antecedente de hepatitis C con manejo con interferón pegilado + ribavirin. Seef, Foster y Poynard encontraron al estudiar el comportamiento del virus de la hepatitis, un estado de hipercoagulabilidad, que crea interrupción del flujo vascular retinacular en la cabeza femoral, sin incrementar la incidencia de osteonecrosis en este grupo de pacientes. Lauer expone que dichas infecciones virales llevan un proceso autoinmune, las cuales podrían producir vasculitis transitorias. Giampaolo en 2005 reporta la relación entre el uso de interferón en mieloma múltiple y otros padecimientos oncológicos relacionándose con necrosis avascular femoral. Material y métodos: Se valoraron los casos de diagnóstico de osteonecrosis bilateral de la cabeza femoral bilateral. Resultados: Se revisaron 5 pacientes, 4 mujeres y 1 hombre, con el diagnóstico de osteonecrosis bilateral de la cabeza femoral bilateral. Todos con antecedentes de hepatitis C con manejo con interferón pegilado, corroborándose diagnóstico definitivo por patología posterior a artroplastías, realizándose revisión bibliográfica de la relación de esta patología con el uso de interferón en pacientes con hepatitis C. Conclusiones: Al conocer la relación que existe en enfermedades virales como la hepatitis B y C con la presencia de estados de hipercoagulabilidad, procesos autoinmunes que conllevan a vasculitis transitorias y el uso de interferón pegilado 2B, relacionándose a necrosis avascular de las cabezas femorales, conoceremos nuevas causas asociadas no traumáticas a este padecimiento.


Background: Avascular necrosis of the femoral head is a frequent condition in patients with a history of trauma. The major pathologic causes include vascular diseases, malignancies, hypercoagulability states, long-term steroid treatment, and some patients have a history of hepatitis C infection treated with pegylated interferon and ribavirin. Upon studying the behavior of the hepatitis C virus, Seef, Foster and Poynard found a hypercoagulability state that causes interruption of retinacular blood flow to the femoral head, without an increased incidence of osteonecrosis in this patient group. Lauer states that such viral infections involve an autoimmune process and may result in transient vasculitides. Giampaolo, in 2005, reported the relationship between interferon use for multiple myeloma and other cancers and femoral avascular necrosis. Material and methods: Cases with a diagnosis of bilateral osteonecrosis of the femoral head were assessed. Results: Five patients were included, 4 females and one male, with a diagnosis of bilateral osteonecrosis of the femoral head. All of them had history of hepatitis C infection treated with pegylated interferon. The final diagnosis was proven by pathology after arthroplasty. A literature review was made of articles on the relationship between this condition and interferon use in patients with hepatitis C infection. Conclusions: Finding out the relationship between viral diseases such as hepatitis B and C infection and hypercoagulability states, autoimmune processes leading to transient vasculitides and the use of pegylated interferon 2B, will help us discover new nontraumatic causes associated with this condition.

ABSTRACT

Introducción: Las fracturas de húmero proximal de tres o más fragmentos presentan riesgo elevado de necrosis, siendo éste el segundo sitio más frecuente sólo después del fémur, presentándose causas traumáticas y no traumáticas, siendo las traumáticas las más comunes, presentando una incidencia de 13 a 34% en fracturas de más de cuatro fragmentos. El propósito de este estudio es valorar el resultado funcional de pacientes con antecedente de fractura humeral proximal y osteonecrosis con manejo conservador. Material y métodos: Se presenta un estudio descriptivo, retrospectivo, observacional con seguimiento de 6 a 12 meses de pacientes mayores de 60 años con diagnóstico de fractura de húmero proximal con manejo conservador, en el período comprendido de Enero de 2004 a Noviembre de 2009, se seleccionaron 122 pacientes que cumplían los criterios de inclusión, perdiendo el seguimiento de 12 de ellos, con edad promedio de 71.02 años con rango de 60 a 92 años, 41 hombres y 69 mujeres, realizándose escalas de DASH y CONSTANT. Resultados: Posterior a la realización de las escalas de valoración funcional se realiza la validación de dichos resultados obteniendo un coeficiente de correlación de 0.80 siendo estadísticamente significativo. Conclusión: El tratamiento conservador debe ser reservado sólo en pacientes que cumplan con las características necesarias. Dependiendo del tipo de fractura y las características del individuo, el tratamiento siempre está enfocado a la estabilización y a la movilización temprana y en la obtención de la recuperación funcional precoz. Encontrando en este estudio que las fracturas tratadas de forma conservadora, desarrollan algún estadio de osteonecrosis de la cabeza pero con adecuada función casi similar a la extremidad sana.


Introduction: Fractures of the proximal humerus resulting in three or more fragments represent a high risk of necrosis. The former is the second most frequent site of necrosis, only after the femur, due to either traumatic or nontraumatic causes. The former are the most common, with an incidence rate of necrosis of 13-34% in fractures with more than four fragments. The purpose of this study is to assess the functional outcome of patients with a history of fracture of the proximal humerus and osteonecrosis treated conservatively. Material and methods: This is a descriptive, retrospective, observational study with a 6-12 month follow-up of patients older than 60 years of age with a diagnosis of fracture of the proximal humerus managed conservatively between January 2004 and November 2009. One hundred and twenty-two patients met the inclusion criteria and 12 were lost to follow-up. Mean age was 71.02 years with a range between 60 and 92 years; 41 males and 69 females. The DASH and CONSTANT scales were applied. Results: After applying the functional assessment scales and validating the results, the correlation coefficient obtained was 0.80, and it was statistically significant. Conclusion: Conservative treatment should be used only in patients who meet the necessary criteria. Depending on the type of fracture and the patient's characteristics, treatment should always be aimed at stabilization, early mobilization, and early functional recovery. This study found that fractures treated conservatively eventually develop some degree of osteonecrosis of the head, but they have proper function, similar to that of a healthy limb.
