Project description:Osteoid osteoma has been reported infrequently around the elbow joint, and is usually treated with radiofrequency ablation or open excision. Elbow arthroscopy is useful for excision of accessible lesions, and the accompanying elbow stiffness can be treated concurrently. This report describes an arthroscopic excision of an osteoid osteoma located in the juxta-articular distal humeral bone. An initial adhesiolysis and capsulectomy is performed to gain access to the region above the capitellar articular margin. A 70° arthroscope is necessary to visualize this region via the anteromedial portal. An accessory lateral portal is used to detach the capsule from the distal humerus; the scar tissue overlying the lesion is debrided and the circumferential lesion is visualized and probed for identification of its extent. A biopsy is performed, and thereafter the lesion is excised piecemeal. The sclerotic margins are curetted, and radiofrequency ablation is performed. The technique is cosmetic and minimally invasive, and can be performed in revision scenarios involving recurrences after open surgery or needle radiofrequency thermal ablation. Early rehabilitation restores range of motion and strength. Technical tips for identification and curettage of the lesion are presented.

Project description:Osteoid osteoma is a benign tumor that can cause significant pain and disability. Excision of the tumor can be accomplished with open surgery or, as advocated in recent years, with computed tomography (CT)-guided radiofrequency ablation. In this article, a unique arthroscopic approach to excise an osteoid osteoma of the talus is presented. This was possible by relying on a clear intra-articular prominent osteophyte, which was used as a landmark to indicate tumor location in accordance with preoperative CT views. This technique enabled excision of the tumor with concomitant arthroscopic decompression of the osteophyte, which contributed to symptoms of anterior ankle impingement.

Project description:PurposeTo assess efficacy and safety of imaging-guided radiofrequency ablation (RFA) of Osteoid Osteoma (OO) in both typical and atypical sites.Methods and materialsBetween January 2014 and March 2019, 102 consecutive percutaneous RFA were performed and retrospectively reviewed. The procedures were performed using a RFA bipolar ablation system (Covidien, exposed tip of 0.7-1cm), under Computed Tomography (CT) guidance or using a navigation system (Masmec) under CT and Cone Beam CT (CBCT) guidance. Patients were followed up over 24 months. Clinical success and recurrences were considered on the base of established criteria. In patients with clinical failure and/or imaging evidence of relapse, retreatment was considered.ResultsAdministered power per-procedure was ≤8 W (mean temperature, 90°C). The pre-procedure average value of visual analog scale (VAS) was 8.33+/-0.91. Primary and secondary success rate 96.08% (98/102) and100% (102/102), respectively. No major complication was described. Technical success was proved in every patient by CT scan acquisition after needle positioning. Relapse and tumour location were significantly correlated (p-value = 0.0165). The mean dose-length product was 751.55 mGycm2. Advanced bone healing was noted in 68 lesions after 1y-follow up and in 86 lesions after 2y-follow up.ConclusionImaging-guided percutaneous RFA is a highly effective technique for OO, both in typical and atypical sites. CT or CBCT guidance, navigation systems and operator experience grant the technical success, which is the most crucial parameter affecting outcome.

Project description:Background and purposeOsteoid osteoma is a benign skeletal tumour that accounts for 2-3% of all bone tumours. The male-to-female ratio is around 4:1 and it predominates in children and young adults. The most common symptom is pain, frequently at night-time. Historically the main form of treatment has been surgical excision. With the development of Radiofrequency Ablation (RFA) there is a percutaneus alternative. Success rates of RFA are lower but the main advantage is the minimal invasive character of the therapy and the low complication rate. As a result of the minimal invasiveness the hospitalization- and rehabilitation periods are relatively short. However, in current literature no values for accuracy and precision are known for the CT-guided positioning.MethodsAccuracy and precision of the needle position are determined for 86 procedures. Furthermore the population is divided into groups based on tumour diameter, location and procedure outcome.ResultsThe clinical success rate was 81.4%. In 79% of procedures complete ablation was achieved. Accuracy was 2.84 mm on average, precision was 2.94 mm. Accuracy was significantly lower in more profound lesions. Accuracy in tibia and fibula was significantly higher compared to the femur. No significant difference was found between different tumour diameters.InterpretationThe accuracy and precision found are considered good. Needle position is of major importance for procedure outcomes. The question however rises how the results of this therapy will turn out in treatment of larger tumours.

Project description:Osteoid osteoma (OO) is the most commonly seen benign bone-forming lesion. It can occur anywhere, including the metaphyseal regions of small and large bones. We present 2 cases that underwent an arthroscopic technique for removal of OO of the femoral neck. The diagnosis was confirmed by computed tomography in addition to magnetic resonance imaging. The lesions were accessed arthroscopically and excised by unroofing and curettage. The clinical and radiographic findings are presented, along with the surgical management. The patients improved dramatically postoperatively. OO of the femoral neck should be included in the differential diagnosis of hip pain in young patients. Arthroscopic excision and curettage provide a good choice for management, with low morbidity and rapid recovery.

Project description:Osteoid osteoma frequently requires surgical treatment, especially among young, active patients. However, surgeons are reluctant to perform open surgery for an osteoid osteoma of the femoral neck area because the conventional surgical approach requires a large incision in muscular patients, and percutaneous resection with a trephine has the attendant risk of subsequent fracture. Recently, arthroscopic excision of an osteoid osteoma has been reported as a less invasive, safer procedure than traditional open curettage. Hip arthroscopy using the burr-down technique under C-arm guidance to locate and remove the lesion of the femur neck has also shown promise. The presented technique minimizes muscle damage around the femur and enables surgeons to confirm complete resection of the lesion through direct, detailed visualization. Furthermore, early return to previous activity can be achieved after excising the lesion located at the calcar femorale, which is an area with a heavy weight-bearing load. The objective of this Technical Note was to describe our preferred technique for the surgical excision of osteoid osteoma located at the base of the femoral neck through the use of arthroscopy.

Project description:Osteoid osteoma (OO) is a benign, solitary bone tumor of the long bones of the lower limbs and accounts for 10% to 12% of all benign bone. However, an OO of the femoral neck is extremely rare and difficult to treat. Arthroscopic excision of OO of the femoral neck has many advantages. We report a 15-year-old patient with OO of the femoral neck which was treated with arthroscopic excision. The clinical and radiographic findings along with the surgical management of the lesion are presented. The pain disappeared immediately after the operation. At the 14 months' followup, the patient was pain free, and there was no evidence of recurrence.

Project description:Intra-articular osteoid osteoma (OO) is uncommon, especially in the hip joint. Delayed treatment may cause early osteoarthritis; however, diagnosis and complete excision are often challenging. We describe the feasibility of the combination of T2 mapping magnetic resonance imaging evaluation and arthroscopic excision of OO in the acetabulum. A 12-year-old boy presented with a 6-month history of hip pain. An undifferentiated tumor of the medial wall of the acetabulum was suspected on radiographs and computed tomography. T2 mapping showed joint effusion, and the T2 value of the acetabular cartilage just above the tumor was significantly high. These findings suggested OO in the acetabulum. An arthroscopic excision was performed for biopsy and excision of the tumor to avoid damage to the normal cartilage and growth plate. Histologic examination confirmed the OO. At 16 months' follow-up, there was no evidence of recurrence. This is the first report to evaluate intra-articular OO by T2 mapping and to treat it arthroscopically. Arthroscopic treatment assisted by T2 mapping has excellent potential as a minimally invasive technique to enable us to approach the tumor from the area of discriminative abnormal cartilage with minimal damage to the normal cartilage and surrounding tissue.

Project description:Osteoid osteoma (OO) of the coracoid is a rare entity that may present with variable symptoms from shoulder leading to delay in diagnosis and treatment. We present the clinical and radiological findings and management of one such case along with a review of similar cases reported in the literature. There was a delay of 2 years in diagnosis, which was later confirmed by computed tomography in addition to magnetic resonance imaging (MRI). The lesion was accessed arthroscopically and excised by unroofing and curettage. "OO" should be included in the differential diagnosis of shoulder pain in young patients not responding to long-term conservative treatment. Arthroscopic excision and curettage provide a good choice for management, with low morbidity and rapid recovery.

Project description:Osteoid osteoma is a benign osteoblastic tumor that occurs in the subcortical shaft and metaphysis of the long bones of the lower extremities; however, intra-articular lesions are also possible. Intra-articular osteoid osteomas are rare, and clinical symptoms are often less specific and, thereby, may lead to misdiagnosis. The definitive treatment for osteoid osteoma is the excision of the nidus. We present the case of a 23-year-old man with a 4-year history of right anterior hip pain, subsequently diagnosed with a subarticular osteoid osteoma located in the right anterior acetabulum. Hip arthroscopic excision of the juxta-articular osteoid osteoma is presented as an effective treatment, with the advantage of less potential damage to normal bone and cartilage, as well as the additional benefits available with hip arthroscopy.
