[Percutaneous radiofrequency ablation of osteoid osteoma: results from 9 years of experience in a third-level center.] / Ablación percutánea por radiofrecuencia de osteoma osteoide: resultados en 9 años de experiencia en un centro de tercer nivel.

Introduction: Osteoid osteoma is a benign bone tumor that accounts for roughly 2-3% of primary bone tumors and up to 10-12% of benigns bone neoplasms. It is most commonly seen in young adults, and shows male predominance. Over the last years, minimally invasive thermal ablation techniques such as radiofrequency ablation have gained popularity over classical surgery. In this study we evaluate results and complications of CT guided osteoid osteoma radiofrequency ablation. Materials and methods: In this retrospective cohort study all patients that were diagnosed with osteoid osteoma and treated using radiofrequency ablation between January 2014 and December 2022 were included. Pain was assessed using Visual Analog Scale (VAS) pre and post procedure. Technical success was established as positioning of the radiofrequency electrode in the nidus. Primary clinical success was defined as absence of pain after one radiofrequency session. All patients that required a second radiofrequency ablation were included in the overall clinical success group. Results: During the studied period, 61 osteoid osteoma radiofrequency ablations were performed. Fiftyseven of them were included in this study, 32 were men and 25 female. Pre procedure median pain was 9 according to VAS score. Only 23 patients were treated as outpatient, the rest stayed in hospital for 24 hours. Median follow up time was 21,7 months (SD 8,3). Biopsy was performed in 52 patients. Technical success was accomplished in 57 patients (100%). Primary clinical success was 80,7% (46 patients). Those who continued with pain or had recurrence after a symptoms free period (11 patients), were treated with a second radiofrequency ablation, achieving an overall success rate of 94,7%. Only one patient suffered a minor complication (1,7%). Conclusion: CT guided osteoid osteoma radiofrequency ablation is a safe, effective and low complication rate procedure, that can be performed on an outpatient basis. We believe it should be considered as a first line treatment option for osteoid osteoma.

Introducción: El osteoma osteoide es un tumor óseo benigno, que representa el 2-3% de las neoplasias óseas primarias y hasta el 10-12% de los tumores óseos benignos. Tiene mayor incidencia en adultos jóvenes, con predominancia masculina. En los últimos años las técnicas de termoablación mínimamente invasivas han sido utilizadas para el tratamiento del osteoma osteoide, como alternativa a la cirugía clásica. En este estudio evaluaremos los resultados y complicaciones de ablación por radiofrecuencia de osteoma osteoide. Materiales y métodos: Se analizó una cohorte de pacientes en forma retrospectiva con diagnóstico de osteoma osteoide tratados con radiofrecuencia en el Hospital Italiano de Buenos Aires desde Enero del año 2014 hasta Diciembre del año 2022. Todos los pacientes fueron evaluados con la Escala Visual Analógica del dolor (EVA) pre y post procedimiento. El éxito técnico del procedimiento fue considerado como el correcto posicionamiento del electrodo de radiofrecuencia en el nido de la lesión, y el éxito clínico primario como ausencia de dolor post procedimiento. Mientras que los pacientes que requirieron de una segunda sesión de radiofrecuencia para controlar los síntomas serán incluidos como éxito clínico secundario. Resultados: Durante el período mencionado se realizaron 61 ablaciones percutáneas de osteoma osteoide. Se incluyeron en el análisis 57 pacientes, 32 fueron hombres y 25 mujeres. La media de dolor medido por EVA pre procedimiento fue 9. Del total de los pacientes, 23 fueron tratados de manera ambulatoria, el resto permanecieron internados durante 24hs. El tiempo medio de seguimiento fue de 21,7 meses (DS8,3). Se realizó biopsia de la lesión durante el procedimiento en 52 pacientes. Se logró el éxito técnico en 57 pacientes (100%), de ellos el éxito clínico primario se logró en 46 pacientes (80,7%). Los 11 pacientes que continuaron con dolor o presentaron recurrencia de los síntomas luego de un período asintomáticos fueron tratados con una segunda sesión de radiofrecuencia, logrando un éxito clínico secundario 94,7%. Un solo paciente presentó complicaciones post procedimiento (1,7%), correspondiente a hematoma en la planta del pie. Conclusión: Podemos concluir que la ablación percutánea por radiofrecuencia de OO guiada por tomografía en manos de expertos, es un procedimiento seguro, de alta efectividad y baja tasa de complicaciones que puede realizarse de manera ambulatoria. Por lo que consideramos que debe ser tenida en cuenta como primera elección para el tratamiento de esta patología.

[Ribbing disease: apropos of a case]. / Enfermedad de Ribbing: a propósito de un caso.

Ribbing's disease is a rare form of sclerosing bone dysplasia characterized by exuberant yet benign endosteal bone, and periosteum formation in the diaphysis of long bones. Diagnosis relies on exclusionary criteria, as the primary clinical manifestations entail progressive pain unresponsive to analgesic therapy, accompanied by serological markers within normal ranges. Pain management constitutes the cornerstone of treatment, with surgery appearing to offer the most efficacious approach, despite the absence of a standardized therapeutic algorithm. The diagnostic and therapeutic delays associated with Ribbing's disease, reaching up to 16 years, exert a profound impact on patients' quality of life. Hence, the purpose of our work is to present a case report of Ribbing's disease and conduct a comprehensive literature review on the subject matter.

La enfermedad de Ribbing es una forma rara de displasia ósea esclerosante caracterizada por una formación exuberante, aunque benigna, de hueso endóstico y periostio en la diáfisis de los huesos largos. El diagnóstico se basa en criterios de exclusión, ya que las manifestaciones clínicas principales implican dolor progresivo que no responde a analgésicos, acompañado de marcadores serológicos normales. El manejo del dolor constituye la piedra angular del tratamiento y la cirugía parece ofrecer el enfoque más efectivo, a pesar de no contar con un algoritmo terapéutico estandarizado. Los retrasos diagnósticos y terapéuticos asociados con la enfermedad de Ribbing, que pueden alcanzar hasta 16 años, impactan profundamente en la calidad de vida de los pacientes. Por lo tanto, el propósito de nuestro trabajo es presentar un reporte de caso de la enfermedad de Ribbing y realizar una revisión bibliográfica exhaustiva sobre el tema.

Resección de osteoma osteoide vertebral asistida por planificación 3D. Presentación de un caso / Resection of spinal osteoid osteoma assisted by 3D planning. Case report

La localización vertebral de una lesión compatible con un osteoma osteoide requiere, muchas veces, su resección en bloque mar-ginal mediante cirugía. El objetivo de este artículo es informar sobre el uso de la tecnología en impresión 3D para desarrollar guías de corte y así lograr una resección segura y completa de un osteoma osteoide de L1. Presentamos a un varón de 13 años, operado de un osteoma osteoide de L1 y detallamos la planificación preoperatoria con asistencia de la tecnología 3D, la técnica quirúrgica mediante guías de corte impresas y un modelo real de la columna lumbar y el control posoperatorio. Conclusiones: Ante la indicación de cirugía para una lesión compatible con osteoma osteoide en la columna debe decidirse entre la posibilidad de resección intralesional abierta o percutánea y la resección marginal en bloque. Para localizar la lesión durante la cirugía, se utilizan diferentes métodos. En nuestro Servicio, estamos utilizando la tecnología 3D para la planificación preoperatoria de múltiples enfermedades traumatológicas agudas y las secuelas. Esto nos permite una mayor precisión y seguridad en la identificación de los márgenes de resección intraoperatoria, reduciendo, al mínimo, la extracción de tejidos sanos y evitando la inestabilidad posoperatoria. Nivel de Evidencia: IV

The vertebral location of a lesion compatible with an osteoid osteoma often requires a marginal en bloc resection. Our objective is to present the use of 3D printing technology for the development of specific cutting guides that achieve a safe and complete resection of an L1 osteoid osteoma. We present the case of a 13-year-old male who underwent surgery for an L1 osteoid osteoma, de-tailing the preoperative planning assisted by 3D technology, the surgical technique using 3D printed cutting guides, a real model of the lumbar spine, and the postoperative control. Conclusion: Before the surgical indication of a lesion compatible with an osteoid osteoma in the spine, we must decide between the possibility of an open intralesional resection or percutaneous and marginal en bloc resection. Different methods can be used for the intraoperative location of the lesion. In our department, we use 3D technology for preoperative planning of multiple acute and post-traumatic pathologies. This allows us to be precise and safe in the identification of intraoperative resection margins, minimizing the removal of healthy tissues and avoiding postoperative instability.

Repercusión biomecánica derivada de un osteoma en el tercio proximal del fémur: a propósito de un caso / Biomechanical Impact Derived From an Osteoma in the Proximal Third of the Femur: Report of a Case

Introducción: El osteoma osteoide es un tumor óseo benigno, que no tiene potencial de crecimiento por lo que su tamaño no supera 1,5 cm pese a que la esclerosis que lo rodea le da un aspecto mayor. Afecta con mayor frecuencia a los varones jóvenes, y la mayoría de las veces aparece en las tres primeras décadas de la vida. Objetivos: Mostrar las repercusiones biomecánicas derivadas de un osteoma osteoide en el trayecto de la cintilla iliotibial y sus influencias por cadenas musculares descendentes sobre el miembro inferior. Presentación del caso: Se presenta una paciente de 24 años que acude a la consulta por presentar dolor a nivel de la cara externa del fémur derecho desde hace dos años; que se agudiza fundamentalmente con la marcha. Tras realizar las pertinentes exploraciones y pruebas diagnósticas por imagen, no se observan hallazgos clínicos significativos, por tanto se pauta tratamiento antiinflamatorio por vía oral y se efectúa estudio biomecánico y postural en el cual se detecta pie valgos bilaterales, inestables, con mayor relevancia en el pie derecho. La paciente acude nuevamente al no encontrar mejoría, se realiza telemetría del miembro inferior y resonancia magnética del fémur derecho. La imagen para diagnóstico da como resultado la presencia de una masa compatible con un osteoma osteoide de 11 x 4 mm en el tercio proximal lateral del fémur derecho. Conclusiones: Una lesión neoplásica que afecte al trayecto de un grupo muscular con repercusión biomecánica puede realizar compensaciones a diferentes niveles, por tanto, es necesaria la actuación de un equipo multidisciplinario para restablecer la marcha. Las sinergias entre el tratamiento conservador y quirúrgico provocan un mayor porcentaje de éxito(AU)

Introduction: Osteoid osteoma is a benign bone tumor, which has no growth potential, consequently its size does not exceed 1.5 cm despite the fact that the surrounding sclerosis gives it a larger appearance. It most often affects young men, most often appearing in the first three decades of life. Objectives: To show the biomechanical repercussions derived from an osteoid osteoma in the trajectory of the iliotibial band and its influences by descending muscle chains on the lower limb. Case report: We report a 24-year-old female patient who came to the consultation due to pain on the external face of her right femur for two years. This pain worsened mainly by walking. After carrying out the pertinent explorations and diagnostic imaging tests, no significant clinical findings were observed, therefore, oral anti-inflammatory treatment was prescribed and biomechanical and postural study was carried out, which showed bilateral, unstable valgus foot, with higher relevance on the right foot. The patient came again when she had no improvement, telemetry of her lower limb and magnetic resonance imaging of her right femur were performed. The diagnostic image revealed the presence of a mass compatible with an 11 x 4 mm osteoid osteoma in the proximal lateral third of her right femur. Conclusions: A neoplastic lesion that affects the trajectory of a muscle group with biomechanical repercussions can carry out compensations at different levels, therefore, the action of a multidisciplinary team is necessary to restore gait. Synergies between conservative and surgical treatment lead to a higher success rate(AU)

Osteoma osteoide: causa poco frecuente de dolor crónico en la muñeca en una niña / Osteoid osteoma: unusual cause of chronic pain in the wrist in a child

El osteoma osteoide es una lesión ósea benigna que, habitualmente, se acompaña de clínica típica caracterizada por dolor nocturno que mejora con antiinflamatorios no esteroideos. Aunque la presentación clínica es típica, con frecuencia, es común la demora diagnóstica, en especial, en los casos con localización atípica.Se presenta el caso de una paciente de 10 años con dolor en la muñeca izquierda de dos años de evolución con diagnóstico de osteoma osteoide localizado en el hueso grande del carpo. La localización atípica de la lesión conllevó un retraso diagnóstico importante

Osteoid osteoma is a benign bone lesion that is usually accompanied by a typical clinical condition characterized by night pain that improves with non-steroidal anti-inflammatory drugs. Although the clinical presentation is frequently typical, diagnostic delay is common, especially in cases with an atypical location.We report the case of a 10-year-old patient with left wrist pain of two years of evolution with diagnosis of osteoid osteoma located in capitate bone. The atypical location of the lesion led to a significant diagnostic delay.

Resection of Bone Tumor Guided by Gamma Probe and Evaluation of Postoperative Pain / Ressecção de tumor ósseo guiado por Gamaprobe e avaliação do quadro álgico pós-operatório

Abstract Osteoid osteoma is a benign neoplasm commonly found in young men, but that can be found in every age, which affects mainly long bones, clinically characterized by continuous and limiting pain that is relieved by salicylates. It is a small lesion composed of immature osteoid tissue, central hypervascularization and surrounding sclerotic area. Its diagnosis is performed by the clinic and aided by imaging tests, such as common radiography and computed tomography. Radiography shows a central radiolucent lesion and peripheral sclerosis. The biopsy takes place only in cases of diagnostic doubt. Surgical treatment involves resection of the niche, providing greater symptomatic relief, as well as percutaneous techniques. The technique of radioisotope-guided resection has good acceptance in the scientific community for its fast surgical procedure directed to the lesion; however, the percutaneous technique that stands out is radiofrequency ablation. In the present study, all of the patients submitted to the technique presented total improvement of the pain.

Resumo O osteoma osteóide é uma neoplasia benigna comum em homens jovens; porém, pode atingir qualquer idade, acomete preferencialmente ossos longos, e é caracterizada por dor contínua e limitante que é aliviada por salicilatos. É uma lesão de tamanho pequeno, composta por tecido osteóide imaturo, hipervascularização central e área esclerótica circundante. O diagnóstico é realizado pela clínica e auxiliado por exames de imagem, como radiografia comum e tomografia computadorizada. À radiografia, apresenta-se como uma lesão radiolucente central e esclerose periférica. A biópsia está indicada somente nos casos de dúvida diagnóstica. O tratamento cirúrgico envolve a ressecção do nicho, proporcionando maior alívio sintomático, assim como as técnicas percutâneas. A técnica de ressecção guiada por radioisótopo tem boa aceitação na comunidade científica por tornar o procedimento cirúrgico mais rápido e dirigido para a lesão, ainda que o padrão ouro de tratamento seja a técnica percutânea de ablação por radiofrequência. É válido ressaltar que, no presente estudo, todos os pacientes submetidos à resecção cirúrgica apresentaram regressão do quadro álgico.

Comparison of Noninvasive High-Intensity Focused Ultrasound with Radiofrequency Ablation of Osteoid Osteoma.

OBJECTIVE: To evaluate clinical feasibility and safety of magnetic resonance imaging-guided high-intensity focused ultrasound (MR-HIFU) treatment of symptomatic osteoid osteoma and to compare clinical response with standard of care treatment. STUDY DESIGN: Nine subjects with radiologically confirmed, symptomatic osteoid osteoma were treated with MR-HIFU in an institutional review board-approved clinical trial. Treatment feasibility and safety were assessed. Clinical response was evaluated in terms of analgesic requirement, visual analog scale pain score, and sleep quality. Anesthesia, procedure, and recovery times were recorded. This MR-HIFU group was compared with a historical control group of 9 consecutive patients treated with radiofrequency ablation. RESULTS: Nine subjects (7 male, 2 female; 16 ± 6 years) were treated with MR-HIFU without technical difficulties or any serious adverse events. There was significant decrease in their median pain scores 4 weeks within treatment (6 vs 0, P < .01). Total pain resolution and cessation of analgesics were achieved in 8 of 9 patients after 4 weeks. In the radiofrequency ablation group, 9 patients (8 male, 1 female; 10 ± 6 years) were treated in routine clinical practice. All 9 demonstrated complete pain resolution and cessation of medications by 4 weeks with a significant decrease in median pain scores (9 vs 0, P < .001). One developed a second-degree skin burn, but there were no other adverse events. Procedure times and treatment charges were comparable between the 2 groups. CONCLUSION: This pilot study shows that MR-HIFU treatment of osteoid osteoma refractory to medical therapy is feasible and can be performed safely in pediatric patients. Clinical response is comparable with standard of care treatment but without any incisions or exposure to ionizing radiation. TRIAL REGISTRATION: ClinicalTrials.govNCT02349971.

Osteoma osteoide de cuello femoral: A propósito de un caso / Femoral neck osteoid osteoma: about a case

El osteoma osteoide es un tumor óseo benigno, de pequeño tamaño, sin potencial de crecimiento. Habitualmente se considera a los tumores óseos benignos y malignos como una causa poco frecuente de cojera en apirexia, siendo más frecuentes las patologías inflamatorias inespecíficas como la sinovitis transitoria de cadera, la enfermedad de Perthes y la condropatía conjugal del adolescente. Se presenta el caso clínico de un escolar de 8 años con una cojera dolorosa en apirexia de 4 meses de evolución con sospecha imagenológica de osteoma osteoide de cuello de fémur. Se decide realizar prueba terapéutica con ácido acetilsalicílico. A las 24 horas el niño se encontraba asintomático. Se indicó procedimiento quirúrgico de resección mediante punción bajo tomografía axial computada. El diagnóstico se confirmó mediante anatomía patológica. Se realizó resección completa del tumor con buena evolución. Es importante desde el punto de vista pediátrico realizar un correcto diagnóstico diferencial entre las diferentes causas de cojera dolorosa en apirexia, basándonos en la historia clínica y la imagenología.

Osteoid osteomas are small benign bone tumors which lack growth potential. All bone tumors, whether benign or malign, are considered a rare cause of apyretic limping, being non-specific inflammatory diseases more frequent, such as transient synovitis of the hip, Perthes disease and adolescent conjugal chondropathy. The study presents the clinical case of an 8 year old school boy with a 4 month evolution painful apyretic limp, being there a suspicion of femoral neck osteoid osteoma according to imaging studies. Therapeutic trial of acetylsalicylic acid was performed. Twenty four hours later the boy was asymptomatic. A tomography-guided puncture was indicated. Clinical diagnosis was pathologically confirmed. Subsequently, complete surgical resection of the tumor was performed, the evolution being favorable. From a pediatric perspective it is important to make an accurate differential diagnosis between the different possible causes of painful apyretic limp, based on clinical history and imaging studies.

Computer modelling of RF ablation in cortical osteoid osteoma: Assessment of the insulating effect of the reactive zone.

PURPOSE: The aim was to study by computer simulations the insulating role of the reactive zone surrounding a cortical osteoid osteoma (OO) in terms of electrical and thermal performance during radiofrequency ablation (RFA). MATERIAL AND METHODS: We modelled a cortical OO consisting of a nidus (10 mm diameter) enclosed by a reactive zone. The OO was near a layer of cortical bone 1.5 mm thick. Trabecular bone partially surrounds the OO and there was muscle around the cortical bone layer. We modelled RF ablations with a non-cooled-tip 17-gauge needle electrode (300 s duration and 90 °C target temperature). Sensitivity analyses were conducted assuming a reactive zone electrical conductivity value (σrz) within the limits of the cortical and trabecular bone, i.e. 0.02 S/m and 0.087 S/m, respectively. In this way we were really modelling the different degrees of osteosclerosis associated with the reactive zone. RESULTS: The presence of the reactive zone drastically reduced the maximum temperature reached outside it. The temperature drop was proportional to the thickness of the reactive zone: from 68 °C when it was absent to 44 °C when it is 7.5 mm thick. Higher nidus conductivity values (σn) implied higher temperatures, while lower temperatures meant higher σrz values. Changing σrz from 0.02 S/m to 0.087 S/m reduced lesion diameters from 2.4 cm to 1.8 cm. CONCLUSIONS: The computer results suggest that the reactive zone plays the role of insulator in terms of reducing the temperature in the surrounding area.

Magnetic Resonance-Guided High-Intensity Focused Ultrasound Ablation of Osteoid Osteoma: A Case Series Report.

Osteoid osteoma is painful benign tumor. The aim of this study was to report our initial experience using magnetic resonance-guided focused ultrasound to treat osteoid osteomas. This retrospective single-center study included four patients treated with magnetic resonance-guided focused ultrasound. They presented with severe pain with reduced quality of life and a poor response to clinical treatment. The pre- and post-treatment evaluation comprised computed tomography and magnetic resonance imaging and focused on quality of life and the impact of pain on daily activities. After treatment, three patients had complete pain resolution with no recurrence. One patient had a recurrence of symptoms after 2 wk and underwent a new successful treatment with increased energy levels. On average, 13 sonications were administered (8-18 sonications/treatment) with an average energy of 2,003 J (range: 1,063-3,522 J). Magnetic resonance-guided focused ultrasound appears to be a feasible, tolerable and effective treatment in selected patients with osteoid osteomas.

Osteoid osteoma of the glenoid: Arthroscopic treatment.

Osteoid osteoma is a benign tumor that is rarely found in the scapula. We report a clinical case involving a 36-year-old female patient who suffered from progressive pain in her right shoulder for 1 year. This patient was initially diagnosed with impingement syndrome and was treated unsuccessfully with medication and physical therapy for approximately 2 months. Based on imaging exams, a juxta-articular osteoid osteoma of the glenoid was identified. The patient underwent a shoulder arthroscopy that included tumor removal and treatment of the resulting chondral lesion. At 6-, 12- and 36-month assessments, the patient was asymptomatic, with a normal range of motion and experienced a pain intensity corresponding to 0 points on the Visual Analog Scale (VAS) and 35 points on the University of California, Los Angeles (UCLA) Scale. A postoperative MRI indicated the absence of any residual tumor tissue or inflammatory signs. We believe that the approach described in this paper allows juxta-articular osteoid osteomas to be accessed in a minimally invasive manner and permits not only adequate resection but also the treatment of chondral lesions that could remain after tumor resection.

Acetabular osteoid osteoma excision by controlled hip dislocation: a case report.

Osteoid osteoma of the acetabulum is rare and its treatment represents a challenge for the orthopedic surgeon. We report a case of a 12-year-old boy with osteoid osteoma in the acetabulum who was treated with a controlled hip dislocation and a gamma probe guide to facilitate excision. The diagnosis was confirmed by pathology. The patient was asymptomatic immediately after surgery and remained so at long-term follow-up.

Open resection of osteoid osteoma guided by a gamma-probe.

Osteoid osteoma is the third most common type of bone tumour. Radiofrequency ablation and other percutaneous procedures are the treatment of choice. However, in some sites these methods are difficult or dangerous. Our objective of this study was to evaluate whether open resection and intraoperative nidus detection with a hand-held gamma probe is an efficient method for treating this type of tumour. Fifty-three patients with osteoid osteomas were submitted to surgical treatment. The first group (gamma group) consisted of 34 patients submitted to open nidus resection guided by a hand-held gamma probe. The control group consisted of 19 patients operated on by conventional technique. In the postoperative period, histopathology, imaging studies, and clinical outcome were evaluated. The gamma group patients were followed up for an average 26.2 months; the control group patients were followed up for an average 38 months. There was no difference with regard to pain relief and histopathology findings between the two groups. However, in the postoperative imaging studies, there was significantly less nidus present in the gamma group (p = 0.01).The gamma probe helped to locate the osteoid osteoma nidus more precisely, as demonstrated by the postoperative imaging studies.
