Purpose: To assess the safety and efficacy of computed tomography-guided radiofrequency (RF) ablation and magnetic resonance-guided focused ultrasound (MRgFUS) in the treatment of osteoid osteoma with a long-term follow-up study.

Materials And Methods: Database research was performed at 2 different centers with experience in musculoskeletal interventions. Both centers, one performing RF ablation and the other MRgFUS, identified 116 patients who underwent either RF ablation or MRgFUS procedures for the treatment of symptomatic osteoid osteoma and retrospectively evaluated data regarding pain scores using a visual analog scale (VAS).

Atraumatic fractures of femur, although not as common as traumatic fractures, are frequently encountered in the clinical practice. They present with non-specific symptoms and can be occult on initial imaging making their diagnosis difficult, sometimes resulting in complications. Overlapping terminologies used to describe these fractures may hamper effective communication between the radiologist and the clinician.

Osteoid osteoma is a painful, benign and common bone tumor that is prevalent in young adults. The typical clinical presentation consists of pain that becomes worse at night and is relieved by nonsteroidal anti-inflammatory drugs. The most common imaging finding is a lytic lesion, known as a nidus, with variable intralesional mineralization, accompanied by bone sclerosis, cortical thickening and surrounding bone marrow edema, as well as marked enhancement with intravenous contrast injection.

A 15-year-old boy presented with left-sided hip pain and imaging consistent with the diagnosis of femoroacetabular impingement. Following hip arthroscopy, which included an osteochondroplasty, labral repair, and capsular repair, the patient's anterior hip pain improved. However, his deep aching hip pain persisted until an ischial osteoid osteoma was identified and treated with radiofrequency ablation.

Osteoid osteomas are benign bone-forming lesions that usually present in adolescence. In patients with severe pain and those not responding to medication, surgical treatment should be considered. Medulloscopy is a standard arthroscopic technique for visualizing the intramedullary canal of the tibia.

Introduction: It is often difficult to clinically and radiologically diagnose intra-articular osteoid osteomas and osteoid osteomas of the hip joint. Treatment can also be difficult due to complex locational relationships. CT-guided radiofrequency ablation is currently the standard form of treatment.

Background: Transoral robotic surgery (TORS) has become a routine technique for treating benign and malignant lesions of the oropharynx with the advantage of reducing morbidity compared to open surgical techniques. However, TORS has not been used routinely for accessing lesions of the spine.

Objective: To describe how TORS can be used to access spinal lesions.

Osteoid osteoma is a benign bone tumor, found in young subjects with typical intense focal pain, nocturnal exacerbation and favorable response to salicylates. Painless osteoid osteomas are rare and their diagnosis is difficult, especially whether their imaging appearance is not typical. We report the case of a 13-year-old boy with a spontaneous painless lesion of the distal phalanx of a toe.

A three-year-old girl experienced a fifteen-month odyssey before the surgical removal of an osteoid-osteoma at the distal phalanx of the thumb to relieve her pain. Osteoid-osteoma is a benign bone tumor rarely found in the hand and not yet described as occurring in a small child in extant literature. In one of the first x-ray examinations, a small foreign body was found in the soft tissues of the right thumb.

Background: Osteoid osteomata comprise approximately 10% of benign bone tumours, with 20% of them being located in the proximal femur and 1-3% in the pelvis. In this meta-analysis, we sought to investigate positive and negative outcomes relating to minimally invasive surgery (MIS), which has superseded open resection and conservative measures over the last decades.

Methods: We searched the PubMed, CENTRAL and grey literature for completed studies published until 10 August 2020.

Background: The traditional treatment for osteoid osteoma is the nidus' surgical resection, which was difficult to eradicate with more invasive and complications because of osteosclerosis surrounding the nidus. This study aimed to analyze the efficacy and safety of percutaneous CT-guided cryoablation of osteoid osteoma at different sites (especially refractory sites such as the spine).

Methods: Fifteen patients with osteoid osteoma who underwent cryoablation at our institution were analyzed retrospectively on their imaging data and clinical visual analog scale (VAS) pain scores before and after the procedure.

Case: We report the case of a 15-year-old male patient presenting with persistent wrist pain after surgical treatment of a triquetral osteoid osteoma. The patient was found to have a persistent nidus. These tumors are difficult to observe intraoperatively or through fluoroscopy, limiting adequate resection and resulting in continued pain.

Spinal pain due to facet joint disease is difficult to diagnose since the clinical history and physical examination findings are usually nonspecific. Facet joint disorders have a wide range of causes and, because of the potential for chronic back pain and disability, an accurate diagnosis is essential. The most frequent cause of pain in facet joints is osteoarthritis, which can be assessed at radiography, CT, or MRI.

Purpose: Osteoid osteoma occasionally occur in the spine, but their malignant transformation is not common. We present an extremely rare case of the malignant transformation of an osteoid osteoma to high-grade osteosarcoma that formed in the pedicle and spread to the lateral mass of the cervical spine.

Case Presentation: We report the case of an 18-year-old man who suffered from neck pain as an initial symptom.

Osteoid osteoma is a benign osteoblastic tumor, quite uncommon in the spine. We report a case of an osteoid osteoma involving the atlas in a 6-year-old boy, who presented with suboccipital pain and torticollis. Initial radiological findings were ambiguous as magnetic resonance imaging showed mainly edema of upper cervical soft tissues.

Atypical Enostoses-Series of Ten Cases and Literature Review.

Department of Orthopedic Surgery 1, SUNY Upstate Medical University, Syracuse, New York, NY 13210, USA.

Bone islands (BI; enostoses) may be solitary or occur in the setting of osteopoikilosis (multiple bone islands) and are sometimes associated with Gardner's Syndrome (osteopoikilosis and colonic polyposis). Characteristic features of bone islands are (1) absence of pain or local tenderness, (2) typical radio dense central appearance with peripheral radiating spicules (rose thorn), (3) Mean CT (computerized tomography) attenuation values above 885 Hounsfield units (HU) (4) absence of uptake on bone scan and (5) radiographic stability over time. However, when enostoses display atypical features of pain, unusual radiographic appearance, aberrant HU, increased radiotracer uptake, and/or enlargement, they can be difficult to differentiate from more sinister bony lesions such as osteoblastic metastasis, low grade central osteosarcoma, osteoid osteoma and osteoblastoma.

Background: Spine osteoblastomas (OBs) are relatively rare. In contrast to osteoid osteoma, radiologic and clinical manifestations of OB can be varied and atypical. Typical radiographic features in spinal OB include peritumoral bone sclerosis, bone marrow edema, and soft tissue edema.
