Comparative study of orthopaedic robot-assisted minimally invasive surgery and open surgery for limb osteoid osteoma / 中国修复重建外科杂志

OBJECTIVE@#To compare the accuracy and effectiveness of orthopaedic robot-assisted minimally invasive surgery versus open surgery for limb osteoid osteoma.@*METHODS@#A clinical data of 36 patients with limb osteoid osteomas admitted between June 2016 and June 2023 was retrospectively analyzed. Among them, 16 patients underwent orthopaedic robot-assisted minimally invasive surgery (robot-assisted surgery group), and 20 patients underwent tumor resection after lotcated by C-arm X-ray fluoroscopy (open surgery group). There was no significant difference between the two groups in the gender, age, lesion site, tumor nidus diameter, and preoperative pain visual analogue scale (VAS) scores ( P>0.05). The operation time, lesion resection time, intraoperative blood loss, intraoperative fluoroscopy frequency, lesion resection accuracy, and postoperative analgesic use frequency were recorded and compared between the two groups. The VAS scores for pain severity were compared preoperatively and at 3 days and 3 months postoperatively.@*RESULTS@#Compared with the open surgery group, the robot-assisted surgery group had a longer operation time, less intraoperative blood loss, less fluoroscopy frequency, less postoperative analgesic use frequency, and higher lesion resection accuracy ( P<0.05). There was no significant difference in lesion resection time ( P>0.05). All patients were followed up after surgery, with a follow-up period of 3-24 months (median, 12 months) in the two groups. No postoperative complication such as wound infection or fracture occurred in either group during follow-up. No tumor recurrence was observed during follow-up. The VAS scores significantly improved in both groups at 3 days and 3 months after surgery when compared with preoperative value ( P<0.05). The VAS score at 3 days after surgery was significantly lower in robot-assisted surgery group than that in open surgery group ( P<0.05). However, there was no significant difference in VAS scores at 3 months between the two groups ( P>0.05).@*CONCLUSION@#Compared with open surgery, robot-assisted resection of limb osteoid osteomas has longer operation time, but the accuracy of lesion resection improve, intraoperative blood loss reduce, and early postoperative pain is lighter. It has the advantages of precision and minimally invasive surgery.

Short-term effectiveness of orthopedic robot-assisted resection for osteoid osteoma / 中国修复重建外科杂志

OBJECTIVE@#To investigate short-term effectiveness and clinical application advantages of orthopedic robot-assisted resection for osteoid osteoma compared with traditional open surgery.@*METHODS@#A retrospective analysis was conducted on clinical data of 48 osteoid osteoma patients who met the selection criteria between July 2022 and April 2023. Among them, 23 patients underwent orthopedic robot-assisted resection (robot-assisted surgery group), and 25 patients received traditional open surgery (traditional surgery group). There was no significant difference ( P>0.05) in gender, age, disease duration, lesion location and size, and preoperative visual analogue scale (VAS) score, and musculoskeletal tumor society (MSTS) score between the two groups. The surgical time, intraoperative blood loss, intraoperative lesion localization time, initial localization success rate, infection, and recurrence were recorded and compared. VAS scores before surgery and at 24 hours, 1, 3, 6, and 9 months after surgery and MSTS score before surgery and at 3 months after surgery were assessed.@*RESULTS@#All patients completed the surgery successfully, with no significant difference in surgical time between the two groups ( P>0.05). Compared to the traditional surgery group, the robot-assisted surgery group had less intraoperative blood loss, shorter lesion localization time, and shorter hospitalization time, with significant differences ( P<0.05). The initial localization success rate was higher in the robot-assisted surgery group than in the traditional surgery group, but the difference between the two groups was not significant ( P>0.05). All patients in both groups were followed up, with the follow-up time of 3-12 months in the robot-assisted surgery group (median, 6 months) and 3-14 months in the traditional surgery group (median, 6 months). The postoperative MSTS scores of both groups improved significantly when compared to those before surgery ( P<0.05), but there was no significant difference in the changes in MSTS scores between the two groups ( P>0.05). The postoperative VAS scores of both groups showed a gradually decreasing trend over time ( P<0.05), but there was no significant difference between the two groups after surgery ( P>0.05). During follow-up, except for 1 case of postoperative infection in the traditional surgery group, there was no infections or recurrences in other cases. There was no significant difference in the incidence of postoperative infection between the two groups ( P>0.05).@*CONCLUSION@#Orthopedic robot-assisted osteoid osteoma resection achieves similar short-term effectiveness when compared to traditional open surgery, with shorter lesion localization time.

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.

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.

[ case report of an ethmoid sinus osteoma with presentation of tension pneumoencephalus]

Osteoid osteoma is a benign tumor, which is mostly seen in the long bones but occasionally originates and grows inside the paranasal sinuses. It rarely may impinge the dura with growing upward inside the ethmoid sinus. As a result, it can cause dural rupture, CSF leak and tension pneumocephalus. This needs complete resection with dural repair as an effective treatment. In this case report, a 72 year old man with osteoid osteoma is reported who had been referred with headache, rhinorrhea, memory loss, mood disorder and mutism. Pneumo-encephalus due to injury of dura of the skull base by a left ethmoid sinus osteoma was later found by CT scan. This tumor was completely resected and dura repaired by a surgical team including neurosurgeon and otorhinolaryngologist. The signs and symptoms were disappeared during the next few days

osteoid osteoma at the child [about 9 cases]

The osteoid osteoma is a benign lesion characterized by multiple clinic and topographic aspects-exposing to diagnostic and therapeutic problems. Through a retrospective study managed form 1981 to 2002, about 9 cases, the diagnostic means and the results of therapeutic follow-up have been rated. The mean age was 10 years old and the sex-ratio was about 1.22. in 66% of the cases, the lesion is localized in the long borne of the lower limb and in 22% of the cases at the level of the rachis. The lesion was diaphysial in 71% of the cases and epihysometaphysial in 29% of the cases. The motive of consultation was a typical pain in 55% of the cases, yielding to the aspirin in 4 times out of 5 and associate to a claudication in 44% of the cases. The scoliotic attitude has been found in 2 cases. We didn't notice any neurologic sign. The preoperative diagnosis has been based on the standard radiography in 44% of the cases, on the scintigraphy and the computerized tomography at the same time in 33% of the cases and the IMR in 11% of the cases. In 2 cases, the diagnosis has been based only on the anatomopathologic study. The surgical exercise was total in 78% of the cases, partial in 22% of the cases and the osseous graft was necessary in 1 case. After a mean recession of 10 months, the evolution was favorable in 67% of the cases, the pain persisted in one case associate to incomplete exercises and two patients have been lost to follow-up. The progress of modern imaging permits now a great diagnostic reliability and therapeutic approach less invasive. Indeed, the location reached the target, because the practice of the scano-assisted Percutaneous resection that has the tendency to substitute for classical surgical treatment

Ablación percutánea mediante radiofrecuencia de osteomas osteoides estratégicamente ubicados: aproximación por vía alternativa / Percutaneous radio frequency ablation of strategically located osteoid osteomas: a \"backdoor\" approach

La ablación percutánea mediante radiofrecuencia (APRF) es una alternativa mínimamente invasiva al tratamiento habitual de resección en block de los osteomas osteoides. La APRF es una alternativa particularmente útil en lugar de la cirugía para el típico osteoma osteoide cuando este se encuentra en localizaciones estratégicas, donde puede existir un aumento del riesgo de injuria a importantes estructuras suprayecentes. En el presente artículo presentamos el tratamiento de dos clásicos osteomas osteoides mediante APRF (90º C durante 5-6 minutos), ubicados en el fémur proximal, inmediatamente distales al trocánter menor. En dichos casos empleamos una vía de abordaje alternativa a través de la cortical opuesta para evitar al nervio ciático así como la musculatura asociada y la vasculatura del comportamiento posterior del muslo. Se observó remisión sintomática completa en el lapso de 24 hs. posteriores al procedimiento, no observándose recidiva clínica en un período de seguimiento de 12 a 18 meses subsiguientes

Experience on 29 cases of osteoid 1982-1997 [in Lebanon]

A review of 29 cases of osteoid osteoma over the past 15 years was carried out. This lesion was noted in several skeletal locations, and mimicked several conditions including inflammatory joint disease, spine derangement, internal derangement of various joints, other tumors both benign and malignant, growth disturbances, dysplasias and feet problems. Orthopedic surgeons are becoming more familiar with the diagnostic symptomatology and sequel. This has allowed an earlier diagnosis, thus preventing permanent deformities. With improvement in diagnostic technology, the lesion is detected earlier, and excised more precisely. Various techniques have been used to both localize and excise the lesion, with minimal disturbance to the involved site, both on an in- and out-patient program, with minimal cost
