NAILING INTERTROCHANTERIC FRACTURES IN GERIATRIC POPULATION: DO WE KNOW IT ALL?

INTRODUCTION AND OBJECTIVES: Pertrochanteric fractures constitute an important part of the daily activity of the orthopaedic surgeon. The aim of this study was to carry out an analysis of pre-, intra- and post-operative radiographic parameters and to analyze the results of stable and unstable intertrochanteric fractures treated with short nails with dynamic distal locking. MATERIALS AND METHODS: Retrospective study in our center, between the years 2017-2021 of patients over 65 years of age with pertrochanteric fracture. We included 272 patients treated with Gamma3 Nail (Stryker®) with dynamic distal locking. As variables, we recorded: age, medical comorbidities, fracture pattern according to AO/OTA, osteopenia according to Singh's classification, preoperative (such as diaphyseal extension), intraoperative (such as tip to the apex or medial cortical support) and postoperative radiographic parameters (such as time to consolidation or loss of reduction), pre- and postoperative Barthel, quality of life and complications and reinterventions, such as non-union or cut-out. RESULTS: The mean age was 83.28 years (65-102). 204 cases were women (75%). The average follow-up was 18.2 months (12-24). The distribution according to AO/OTA classification was 85.7% 31.A1; 12.5% 31.A2; 1.9% 31.A3. Radiographic consolidation was obtained in 97.4% of cases. Tip to apex distance was less than 25mm in 95.6% of cases. Medial cortical support was positive or neutral in 88.6% of cases. Sixty cases (22.1%) of screw back-out were recorded. Eight reinterventions (2.9%) were performed, corresponding to three cut-outs (1.1%), three nonunions (1.1%), one avascular necrosis (0.4%) and one secondary hip osteoarthritis (0.4%). CONCLUSIONS: Short nail with dynamic distal locking offers good clinical, radiological and functional results in all types of AO/OTA patterns, without increasing the complication rate, as long as there is an appropriate tip-to-the-apex distance and good medial cortical support.

Understanding limb necrotizing infections: A comprehensive approach.

INTRODUCTION: Necrotizing soft tissue infections (NSTI) are increasing, posing a significant risk of morbidity and mortality. Due to nonspecific symptoms, a high index of suspicion is crucial. Treatment involves a multidisciplinary approach, with broad-spectrum antibiotics, early surgical debridement, and life support. This study analyzes the characteristics, demographics, complications, and treatment of NSTI in a hospital in Madrid, Spain. METHODS: A retrospective observational study was conducted, including all surgically treated NSTI patients at our center from January 2016 to December 2022, examining epidemiological and clinical data. The Laboratory Risk Indicator for Necrotizing Fasciitis (LRINEC) was prospectively calculated for all patients. RESULTS: Twenty-two patients (16 men, 6 women, mean age 54.8) were included. Median time from symptom onset to emergency room visit was 3.5 days. All reported severe treatment-resistant pain; sixteen had fever exceeding 37.8°C (72.7%). Skin lesions occurred in twelve (54.5%), and thirteen had hypotension and tachycardia (59.1%). Treatment involved resuscitative support, antibiotherapy, and radical debridement. Median time to surgery was 8.25h. Intraoperative cultures were positive in twenty patients: twelve Streptococcus pyogenes, four Staphylococcus aureus, one Escherichia coli, and four polymicrobial infection. In-hospital mortality rate was 22.73%. CONCLUSIONS: We examined the correlation between our results, amputation rates and mortality with LRINEC score and time to surgery. However, we found no significant relationship unlike some other studies. Nevertheless, a multidisciplinary approach with radical debridement and antibiotic therapy remains the treatment cornerstone. Our hospital stays, outcomes and mortality rates align with our literature review, confirming high morbimortality despite early and appropriate intervention.

External fixation in intra-articular fractures of the calcaneus: Is it a valid option as definitive treatment?

INTRODUCTION: The therapeutic management of calcaneal fractures is currently a major source of controversy in the literature. There is no consensus on the need to treat these injuries conservatively or surgically, nor on the criteria for deciding one option or the other. Although the gold standard has classically been the open approach and osteosynthesis, there are currently minimally invasive techniques that also report good results. Our objective is to present our results and experience with the MBA® Orthofix external fixator in a series of cases of calcaneal fractures. METHODS: We performed a retrospective observational study in our center, between the years 2019 and 2021, of Sanders types II-IV calcaneal fractures operated with MBA® Orthofix external fixator. We recorded a total of 38 patients, 42 fractures. We registered demographic information, intraoperative, postoperative, radiological and functional parameters, using the American Orthopedic Foot and Ankle Society (AOFAS), Manchester-Oxford Foot Questionnaire (MOXFQ), EQ-5D and VAS scales. RESULTS: A total of 26 men and 12 women were included, and the median age was 38 years. Mean follow-up was 24,4 months (6, 8-40, 1). The average time to surgery was 7 days and partial loading was started at 2.5 weeks after external fixation, which was removed at 9.2 weeks. The average Böhler angle correction was 7, 4°, Gissane - 12,2°, length 2 mm and calcaneal width was reduced by 5 mm. We recorded two superficial infections, one peroneal entrapment and three subtalar arthrodesis due to post-traumatic osteoarthritis. The AOFAS obtained was 79.1 + / - 15.7 points, MOXFQ 20.1 + / - 16.1 points, EQ-5D 0.84 + / - 0.2 and VAS 3.3 + / - 1.9. CONCLUSION: The external fixator is an excellent surgical alternative for complex articular fractures of the calcaneus, obtaining clinical and radiological results comparable to other osteosynthesis techniques and significantly reducing soft tissue complications.

Planificar fracturas es sencillo: desarrollo de un método básico de planificación digital basado en la técnica tradicional con lápiz y papel / Fracture planning is easy: Development of a basic method of digital planning based on the traditional pencil and paper technique

Introducción: La planificación preoperatoria constituye una herramienta fundamental en el manejo de fracturas; sin embargo, su aplicación práctica dista de lo deseado, quizá debido a la ausencia de un método básico y sencillo, adaptado a los tiempos actuales. Describimos un método de planificación digital, entre lo tradicional y lo tecnológico, que conserva su esencia educativa, permite comprender la fractura e individualizar la osteosíntesis. Material y métodos: Tras el análisis inicial de la fractura y características del paciente, se realizan diferentes mediciones en las imágenes de Rx y TC con un programa de imagen médica digital. Estas imágenes se copian en un programa de presentación (Microsoft® PowerPoint o Keynote ©Apple Inc.), en el que se reproducen con el puntero del ordenador los principales fragmentos y líneas de fractura. A continuación, estos se mueven a una posición reducida y se representan gráficamente los implantes para la fijación interna junto con un guion de la estrategia quirúrgica. Resultados: Mostramos 4 casos de diferentes tipos de fracturas intervenidas mediante reducción y osteosíntesis tras una planificación preoperatoria según el método descrito. Se detallan los puntos básicos para la planificación quirúrgica, logística, táctica y los resultados radiológicos postoperatorios de cada caso. Conclusiones: A pesar del auge de programas informáticos avanzados de planificación, los métodos tradicionales con lápiz y papel siguen siendo fundamentales, más aún para el traumatólogo en formación. El método de planificación digital descrito resulta muy adecuado para este objetivo, al aunar las ventajas de ambos métodos: sencillez, accesibilidad, rapidez, bajo coste, reproducibilidad, carácter formativo y eficacia y por posibilitar la simulación, correcciones y la reutilización de casos.(AU)

Introduction: Preoperative planning constitutes a fundamental tool in the management of fractures; however, its practical application is far from the desired, perhaps due to the absence of a basic and simple method, adapted to the current times. We describe a digital planning method, halfway between the traditional and the technological, which preserves its educational essence, allows the understanding of the fracture and the individualization of the osteosynthesis. Material and methods: After the initial analysis of the fracture and the patient's characteristics, different measurements are made on X-ray and CT images with a digital medical imaging software. These images are then copied into a presentation program (Microsoft® PowerPoint or Keynote ©Apple Inc.), in which the main fragments and fracture lines are traced with the computer pointer. These are subsequently moved into a reduced position and the implants for internal fixation are graphically represented together with a guide of the surgical strategy. Results: We show 4 cases of different types of fractures operated through reduction and osteosynthesis after preoperative planning according to the described method. The basic points for the surgical planning, logistics, tactics and postoperative radiological results of each case are detailed. Conclusions: Despite rise of advanced planning software, traditional paper and pencil methods are still fundamental, even more so for the trauma surgeon in training. The digital planning method described is very appropriate for this purpose, as it combines the advantages of both methods: simplicity, accessibility, quickness, low-cost, reproducibility, educational character, efficiency and possibility of simulation, corrections and reuse of cases.(AU)

Suprapatellar tibial nailing, why have we changed? / Enclavado de tibia suprapatelar, ¿por qué hemos cambiado?

INTRODUCTION: Endomedullary nailing using the infrapatellar approach (IP) is considered the gold standard for the treatment of tibial diaphyseal fractures, however, it has been associated with greater difficulty in reduction and complications such as malalignment in procurvatum and anterior knee pain. The suprapatellar approach (SP) arises as an alternative to solve these aspects, also being associated with a shorter intraoperative time and a lower dose and fluoroscopy time. MATERIAL AND METHODS: Retrospective comparative study between a group of 22 fractures treated by SP approach and another of 30 fractures intervened by IP transtendinous approach. Perioperative variables were analyzed, as well as clinical, radiological, and functional aspects in outpatient visits at 3, 6 and 12 months. RESULTS: No differences were found between groups in terms of intraoperative time, anemization, quality of reduction or complications during follow-up, among others. At 12 months, 12 (54.5%) SP cases and 16 (53.3%) IP presented anterior knee pain, without significant differences. In the evaluation scales, significant differences were recorded in the IKDC (International Knee Documentation Committee) in favor of the SP technique 88.45 (76.44-91.1) vs. IP 69 (49.95-80) (p=.006), with no significant differences in other functional scales analyzed. CONCLUSIONS: According to what has been described so far in the literature, the present study supports the tendency toward SP nailing by improving the functional results (IKDC) in the medium term compared to the traditional IP technique, without increasing complications. Likewise, surgeons perceive greater technical ease for reduction and simplicity in obtaining intraoperative radiological images.

Introducción: El enclavado endomedular mediante abordaje infrapatelar (IP) se considera el gold estándar del tratamiento de las fracturas diafisarias de tibia, sin embargo, se ha asociado a mayor dificultad para la reducción y complicaciones como la mala alineación en procurvatum y al dolor anterior de rodilla. El abordaje suprapatelar (SP) surge como alternativa para solventar estos aspectos, asociándose también con un menor tiempo intraoperatorio y menor dosis y tiempo de fluoroscopia. Material y métodos: Estudio retrospectivo comparativo entre: un grupo de 22 fracturas intervenidas mediante abordaje SP y otro de 30 fracturas intervenidas por abordaje IP trastendinoso. Se analizaron variables perioperatorias y aspectos clínicos, radiológicos y funcionales en consulta a los 3, 6 y 12 meses. Resultados: No se encontraron diferencias entre grupos en cuanto a tiempo intraoperatorio, anemización, calidad de la reducción, o complicaciones en el seguimiento, entre otros. A los 12 meses, 12 (54,5%) casos SP y 16 (53,3%) IP presentaban dolor anterior de rodilla, sin diferencias significativas. En las escalas de evaluación, se registraron diferencias significativas en la IKDC (International Knee Documentation Committee) a favor de la técnica SP (88,45 [76,44-91,1] vs. IP 69 [49,95-80]) (p=0,006), sin diferencias significativas en otras escalas funcionales analizadas. Conclusiones: En consonancia con lo hasta ahora descrito en la literatura, el presente estudio apoya la tendencia hacia el enclavado SP por mejorar los resultados funcionales (IKDC) a medio plazo respecto a la técnica tradicional IP, sin aumentar las complicaciones. Asimismo se percibe por los cirujanos una mayor facilidad técnica para la reducción y sencillez en la obtención de imágenes radiológicas intraoperatorias.(AU)

Arteriovenograma de cemento óseo en artroplastia de cadera / Cement arteriovenogram after hip arthroplasty

Las altas presiones intramedulares que se alcanzan durante la cementación en la artroplastia de cadera pueden producir la extrusión de este cemento hacia los vasos nutricios femorales, generando una imagen radiográfica característica (arteriovenograma de cemento o cementograma). Presentamos una serie de 14 casos de pacientes intervenidos mediante artroplastia de cadera cementada en los que se observó un cementograma como hallazgo postoperatorio. Ninguno de estos pacientes sufrió complicaciones locales o sistémicas tras la cementación ni durante un seguimiento medio de 3 años. El cementograma es un hallazgo radiográfico postoperatorio que da cuenta de una buena presurización del cemento durante la cirugía y que no se asocia a complicaciones médicas ni a fracturas alrededor del implante femoral

Modern cement implantation techniques during hip arthroplasty rely on high intramedullary pressures which can result in cement extrusion towards femoral nutrient vessels, and thus, the occurrence of a particular image in postoperative radiographs (bone cement arterio-venogram). We report a case series of 14 patients in whom a bone cement arterio-venogram was observed after undergoing a cemented hip arthroplasty. No local or systemic complications developed after cementing nor during a mean follow-up of three years. Bone cement arterio-venogram is a radiologic sign that indicates a good cement pressurisation during surgery and is not associated to medical complications or periprosthetic femoral fractures

Fractures in patients with poliomyelitis: Past or current challenge?

Fractures in poliomyelitic limbs are a challenge to surgeons, due to polio's sequelae and morphological disorders, which make conventional osteosynthesis difficult. We present a retrospective study of 62 patients and 73 non-simultaneous fractures in their lower limbs. Average age was 61,7 years and 53,2% were females. We analyzed the preinjury functional level, etiology of the fracture, fracture pattern, treatment used (be conservative or surgical), and implant used in surgical cases. We treated 85,1% of them surgically and 37,9% of them maintained the same functional situation as before the fracture. 55,4% of them experienced the need to add some mechanical aids after the lesion and 6,8% lost the ability to walk. Most of the surgical treatments employed were similar as the ones used in non-poliomyelitic patients, although some cases required atypical implants, such as a Multiloc (® DePuy Synthes) humeral nail for a tibial shaft fracture, due to narrow bone. Mortality along the 1st year was 2.7%. We found similar functional and radiological results as those described in non-poliomyelitic limbs.

[Comparative study of the treatment of subtrochanteric fractures in elderly patients: reconstruction nail T2 vs long Gamma nail]. / Estudio comparativo del tratamiento de las fracturas subtrocantéreas en pacientes ancianos: clavo de reconstrucción T2 vs clavo Gamma largo.

INTRODUCTION: Subtrochanteric fractures are associated with a high rate of complications. Intramedullary nails have proven to be the best choice for treatment, but no implant has been shown to be superior to another. We want to study the differences between treating subtrochanteric fractures in the elderly with two different types of nails: T2 Recon vs Gamma3 long. MATERIAL AND METHODS: Comparative retrospective study between 2013 and 2015 with 54 patients with subtrochanteric fractures and more than 65 years. The average follow-up is 12 months; 26 patients were treated with T2 Recon, and 28 with Gamma3. The duration of surgery, need for transfusion, evolution and complications of fractures were compared in both groups. RESULTS: The duration of surgery was significantly longer for T2 Recon (p = 0.035), while the need for transfusion and fracture evolution were similar in both groups. Three cases required another surgery to achieve the final consolidation of the fracture. Two of them due to a failure of the T2 Recon implant, which represents 7.69% of the patients in this group, while the other case belonged to the Gamma3 group and it was sufficient to perform a nail dynamization. CONCLUSIONS: We found no statistically significant differences, except for a longer surgical time in the T2 Recon group, being a surgeon-dependent variable that is not enough to prove that one nail is better than another.

INTRODUCCIÓN: Las fracturas subtrocantéreas se asocian a una alta tasa de complicaciones. Los clavos intramedulares han demostrado ser la mejor opción para su tratamiento, pero ningún implante ha demostrado ser superior a otro. El objetivo es estudiar las diferencias entre tratar las fracturas subtrocantéreas en el anciano con dos tipos de clavos diferentes: T2 Recon vs Gamma3 largo. MATERIAL Y MÉTODOS: Estudio retrospectivo comparativo entre los años 2013 y 2015, con 54 pacientes con fracturas subtrocantéreas y más de 65 años. El seguimiento medio es de 12 meses; 26 pacientes fueron tratados mediante T2 Recon y 28 con Gamma3. La duración de la cirugía, necesidad de transfusión, evolución y complicaciones de las fracturas fueron comparadas en ambos grupos. RESULTADOS: La duración de la cirugía fue significativamente mayor para los T2 Recon (p = 0.035), mientras que la necesidad de transfusión y evolución de las fracturas fueron similares en ambos grupos. Tres casos fueron reintervenidos para conseguir la consolidación final de la fractura. Dos de ellos debido a un fallo del implante T2 Recon, lo cual representa 7.69% de los pacientes de este grupo, mientras que el otro caso pertenecía al grupo de los Gamma3 y fue suficiente con realizar una dinamización del clavo. CONCLUSIONES: No encontramos diferencias estadísticamente significativas, exceptuando un mayor tiempo quirúrgico en el grupo de los T2 Recon, siendo una variable cirujano-dependiente que no es suficiente para demostrar que un clavo sea mejor que otro.

Hematomas subcutáneos a tensión por anticoagulantes en ancianos: ¿más morbimortalidad precoz que las fracturas de cadera? / Tension subcutaneous haematomas associated with anticoagulants in the elderly: Do they have earlier morbidity and mortality than hip fractures?

Introducción: Las complicaciones del tratamiento con fármacos anticoagulantes han sido ampliamente descritas, si bien los hematomas a tensión en extremidades se consideran en muchos casos patologías banales. Material y método: Estudio descriptivo retrospectivo entre 2014 y 2017, incluyendo a pacientes con hematomas tras un mínimo traumatismo en extremidades por anticoagulantes intervenidos por Traumatología. Resultados: Se incluyó a 32 pacientes; el 81% eran mujeres, con una edad media de 83,56 años e ICCa de 5,97. La localización anatómica de los hematomas fue: el 65,6% en pierna/pie, el 15,6% en muslo/glúteo y el 18,8% en miembro superior. El 78,13% consumía acenocumarol, el 15,63% HBPM y el 3,13% NACO, siendo el 59,38% de los casos por FA, el 15,63% por valvulopatías/prótesis valvulares y el 12,5% por TEP/TVP. El tiempo medio desde el diagnóstico al drenaje quirúrgico fue de 2,66 días, principalmente por alteraciones de la coagulación. Un 46,88% fueron reintervenidos para nuevo drenaje, cura o cobertura del defecto cutáneo y 3 pacientes precisaron embolización. Fue necesaria la valoración por otras especialidades en el 78,1%. La estancia media fue de 22,34 días y la tasa de mortalidad intrahospitalaria del 9,38%. Conclusión: Los hematomas a tensión por anticoagulantes en extremidades acontecen en pacientes pluripatológicos y ancianos frágiles. Habitualmente el drenaje quirúrgico se retrasa por multitud de factores, lo que conlleva defectos cutáneos amplios que requieren reintervenciones y estancias hospitalarias prolongadas que se asocian a complicaciones médicas. En nuestro estudio, los datos de estancia media y tasa de mortalidad son superiores a los de las fracturas de cadera, por lo que no debemos subestimar esta patología

Introduction: Complications related to anticoagulant therapy have been widely described, although tension haematomas in the extremities are frequently undervalued, and commonly considered banal pathologies. Material and method: Retrospective descriptive study between 2014 and 2017, including patients with limb haematomas after minimal trauma related with anticoagulant therapy, and surgically treated by Traumatology. Results: 32 cases were eventually included, 81% were women, average age of 83.56 years, and a mean aCCI of 5.97. Anatomical location of haematomas was 65.6% in leg/foot, 15.6% in thigh/buttock, and 18.8% in the upper limb. Seventy-eight point thirteen percent received acenocoumarol, 15.63% LMWH, and 3.13% NOACs. Of the cases, 59.38% were due to AF, 15.63% to valvular heart disease/valve prosthesis, and 12.5% to PE/DVT. The mean time from diagnosis to surgical drainage was 2.66 days, mainly as a result of alterations in coagulation parameters. Forty-six point eighty-eight percent were reoperated for new drainage, cure or skin defect coverage, and 3 patients required embolisation. Of the patients, 78% needed consultation with other specialties. The average length of stay was 22.34 days, and the in-hospital mortality rate was 9.38%. Conclusion: Tension haematomas in the extremities associated with anticoagulants occur in patients with multiple comorbidities that make them vulnerable. Surgical drainage is usually delayed by numerous factors which lead to skin defects that require further surgical operations, and prolonged hospital stays that are associated with medical complications. In our study, the average length of stay and in-hospital mortality rate were higher than those for hip fractures, so we should not underestimate this pathology

Tension subcutaneous haematomas associated with anticoagulants in the elderly: Do they have earlier morbidity and mortality than hip fractures? / Hematomas subcutáneos a tensión por anticoagulantes en ancianos: ¿más morbimortalidad precoz que las fracturas de cadera?

INTRODUCTION: Complications related to anticoagulant therapy have been widely described, although tension haematomas in the extremities are frequently undervalued, and commonly considered banal pathologies. MATERIAL AND METHOD: Retrospective descriptive study between 2014 and 2017, including patients with limb haematomas after minimal trauma related with anticoagulant therapy, and surgically treated by Traumatology. RESULTS: 32 cases were eventually included, 81% were women, average age of 83.56 years, and a mean aCCI of 5.97. Anatomical location of haematomas was 65.6% in leg/foot, 15.6% in thigh/buttock, and 18.8% in the upper limb. Seventy-eight point thirteen percent received acenocoumarol, 15.63% LMWH, and 3.13% NOACs. Of the cases, 59.38% were due to AF, 15.63% to valvular heart disease/valve prosthesis, and 12.5% to PE/DVT.

[Surgical treatment of malignant primary tumors of the pelvis on Ennekings zone II]. / Tratamiento quirúrgico de los tumores primarios malignos de pelvis de la zona II de Enneking.

INTRODUCTION: Surgical treatment of malignant bone tumors of the pelvis with periacetabular involvement is constantly evolving. Even though acetabular reconstructions improve quality of life without impairing cancer control, they are not complication free. Our purpose is to describe the functional outcomes and surgical complications of different reconstructive techniques for Enneking zone II tumors. MATERIAL AND METHODS: Fifteen patients underwent surgery for malignant pelvic bone tumors between 2002 and 2012. Seven patients were retrospectively evaluated according to the Enneking and Dunham classification and were found to have periacetabular involvement, as follows: 3 were type II; 1 types I + II; 2 types II + III, and one types I + II + III. Five patients had a standard chondrosarcoma and 2 osteosarcoma. Patients included 4 males and 3 females; mean age was 43 years. The minimum follow-up period was 12 months (mean 6.14 years). All of them underwent cancer resection with periacetabular reconstruction: massive osteochondral allograft in 3 patients, structural allograft and hip arthroplasty in 2 patients, and prosthesis with iliac anchoring in 2. They were clinically, radiologically and functionally evaluated with the MSTS scale (1993). RESULTS: The mean MSTS score 6 months after surgery was 20.71 (69%). Five patients (71.4%) had surgical complications: 2 dislocations of the native femoral head on the allograft; one aseptic prosthetic dislodgement, and 2 deep infections. All patients had free intraoperative borders. CONCLUSIONS: Acetabular reconstructions after oncologic resection for malignant bone tumors seem to provide good functional outcomes. However, only selected cases should undergo surgeries associated with a high complication rate.

Tratamiento quirúrgico de los tumores primarios malignos de pelvis de la zona II de Enneking / Surgical treatment of malignant primary tumors of the pelvis on Enneking's zone II

Resumen: Introducción: El tratamiento quirúrgico de los tumores óseos malignos de pelvis con afectación periacetabular está en continua evolución. Las reconstrucciones acetabulares mejoran la calidad de vida sin perjudicar el control oncológico; sin embargo, no están exentas de complicaciones. Nuestro objetivo es describir los resultados funcionales y las complicaciones quirúrgicas de diferentes técnicas reconstructivas de la zona II de Enneking. Material y métodos: 15 pacientes fueron intervenidos de tumores óseos malignos de pelvis entre 2002 y 2012. Según la clasificación de Enneking y Dunham, hubo siete individuos con afectación periacetabular: tipo II-3, tipo I + II-1, tipo II + III-2, tipo I + II + III-1, que se evaluaron retrospectivamente. Cinco presentaron un condrosarcoma convencional y dos un osteosarcoma. Cuatro eran varones y tres mujeres, con una edad media de 43 años. El seguimiento mínimo fue 12 meses (6.14 años de media). En todos se realizó una resección oncológica con reconstrucción periacetabular: aloinjerto osteocondral masivo en tres sujetos, aloinjerto estructural más artroplastía de cadera en dos personas y dos con prótesis de anclaje ilíaco. Fueron evaluados clínica, radiológica y funcionalmente mediante la escala MSTS (1993). Resultados: La media MSTS a los seis meses de la cirugía fue 20.71 (69%). Complicaciones quirúrgicas aparecieron en cinco casos (71.4%): dos luxaciones de cabeza femoral nativa sobre aloinjerto, una desimplantación protésica aséptica y dos infecciones profundas. Hubo bordes libres intraoperatorios en todos los casos. Conclusiones: Las reconstrucciones acetabulares después de resecciones oncológicas en tumores óseos malignos parecen ofrecer buenos resultados funcionales. Sin embargo, sólo casos seleccionados deberían ser sometidos a intervenciones con alta tasa de complicaciones.

Seguridad y eficacia de la cifoplastia en el tratamiento de la enfermedad tumoral de la columna vertebral / Safety and efficacy of kyphoplasty in the treatment of tumoral disease of the spine

Las fracturas vertebrales en pacientes oncológicos generan dolor e incapacidad, con limitación funcional y disminución de la calidad de vida. El objetivo del estudio es valorar la eficacia y seguridad de la cifoplastia en este tipo de fracturas vertebrales en el momento agudo. Material y métodos. Estudio descriptivo retrospectivo de 75 pacientes oncológicos consecutivos con 122 fracturas vertebrales agudas, que fueron tratados mediante cifoplastia percutánea bilateral con balón, con un seguimiento medio de 11 meses. Resultados. Se produjo mejoría del dolor en el 91% de los pacientes. La mejoría media en la Escala Visual Analógica (EVA) fue de 4,28 puntos (valor preoperatorio 7,49 [DE 1,19], postoperatorio 3,21 [DE 0,95]). Antes de la intervención necesitaban opioides mayores un 53% de los pacientes (40 casos) y al mes de la cirugía solo un 12% (9 pacientes). La calidad de vida determinada por el índice de Karnosfky mejoró de 60,2 (DE 10) a 80,7 (DE 12,1). En un 5,7% de las cifoplastias (7 casos) se encontraron fugas de cemento, todas ellas sin repercusión neurológica. Aparecieron nuevas fracturas en un 14% de las cifoplastias (11 casos). Este subgrupo presentó un empeoramiento discreto de la mejoría clínica adquirida inicialmente. No encontramos ninguna complicación neurológica ni pulmonar relacionada con la técnica quirúrgica que no estuviera justificada por la evolución de la enfermedad. Conclusiones. La cifoplastia constituye un procedimiento eficaz y seguro para el tratamiento de las fracturas vertebrales en pacientes con cáncer (AU)

Vertebral fractures in oncology patients cause significant pain and disability, with decreased quality of life. The aim of the study is to assess the efficacy and safety of kyphoplasty in this type of vertebral fracture in the acute phase. Materials and methods. A retrospective study was conducted on 75 consecutive oncology patients with 122 acute vertebral fractures, who underwent bilateral balloon kyphoplasty, with a mean follow up of 11 months. Results. Almost all (91%) of the patients improved their pain level. The mean improvement in the Visual Analogue Scale (VAS) was 4.28 points (preoperative value 7.49 [SD 1.19], postoperative 3.21 [SD 0.95]). Before surgery, 53% of patients needed major opioids (40 cases), and one month after surgery only 12% (9 patients) required them. Quality of life determined by the Karnofsky index improved from 60.2 (SD 10) to 80.7 (SD 12.1). Cement leaks were found in 5.7% (7 cases), all without neurological repercussions. New fractures appeared in 11 patients. This subgroup showed a slight worsening of the initially acquired clinical improvement. No neurological or pulmonary complications related to surgical technique were found. Conclusions. Kyphoplasty is an effective and safe for treating vertebral fractures in patients with cancer (AU)
