AIMS
Proximal femoral osteoid osteoma (OO) is extremely easy to be misdiagnosed or missed. The purpose of this study was to retrospectively analyze the clinical data of patients with proximal femoral OO in order to determine the clinical manifestation and imaging characteristics of the disease, so as to provide help for the preoperative diagnosis and clinical treatment of proximal femoral OO.
METHODS
This was a retrospective study involving 35 patients with proximal femoral OO admitted into our hospital from January 2015 to January 2021. The baseline characteristics of the participants included; 24 males and 11 females, aged between 13 and 25 (mean 16.2) years old, and the course of the disease was 1 to 14 (mean 6.3) months. We used previous medical experience records of the patients to analyze for the causes of misdiagnosis. Moreover, we compared the difference between preoperative and postoperative treatment practices in alleviating pain in OO patients and restoring hip function. Follow-ups were carried out regularly, and patients advised to avoid strenuous exercises for 3 months.
RESULTS
We followed up 35 patients (25 intercortical, 4 sub-periosteal, and 6 medullary) for an average of 41.4 months. We found that 15 patients (42.9%) had been misdiagnosed of synovitis, perthes disease, osteomyelitis, intra-articular infection, joint tuberculosis and hip impingement syndrome, whose average time from symptoms to diagnosis were 6.3 months. Postoperative pain score and joint function score improved significantly compared with preoperative, and complications were rare.
CONCLUSION
Open surgical resection constitutes an effective treatment for proximal femoral OO by accurately and completely removing the nidus. Wrong choice of examination, and the complexity and diversity of clinical manifestations constitutes the main reasons for the misdiagnosis of proximal femoral OO.

Primary benign bone tumors are uncommon and most often affect children and young adults. They typically are detected incidentally on imaging, though some patients present with pain, swelling, or other symptoms. The four main categories of benign bone tumor are: bone-forming (eg, osteoid osteoma, osteoblastoma, fibrous dysplasia, enostosis), cartilage-forming (eg, osteochondroma, enchondroma), connective tissue, and vascular; the latter two are rare. A fifth category is idiopathic (eg, giant cell tumor, aneurysmal bone cyst, simple bone cyst). Osteochondromas are the most common, accounting for 30% to 35% of benign bone tumors. Giant cell tumors account for 20%, osteoblastomas for 14%, and osteoid osteomas for 12%. All others are less common. Diagnosis mainly is via imaging; biopsy rarely is required. Management varies with tumor type, location, symptoms, and risk of recurrence. Some (eg, enchondroma, osteochondroma, fibrous dysplasia, enostosis) typically are asymptomatic, and generally require no intervention. Others (eg, osteoid osteoma, aneurysmal bone cyst, simple bone cyst) can cause symptoms and require percutaneous ablation or surgery. Still others (eg, giant cell tumor, osteoblastoma) can be aggressive and require surgery and other therapies. Malignant transformation is rare for all benign bone tumors, but patients with these tumors should be monitored with serial imaging.

Background Cryoablation is playing an increasing role in the percutaneous treatment of bone tumors. However, despite its potential advantages over heat-based ablation techniques, the clinical safety and efficacy of cryoablation have not been established for osteoid osteoma treatment. Purpose To evaluate percutaneous CT-guided cryoablation for the treatment of osteoid osteoma in young patients and adults. Materials and Methods This retrospective study reviewed data from 50 consecutive patients who underwent percutaneous CT-guided cryoablation for the treatment of osteoid osteoma between January 2013 and June 2019 in a single institution. In 30 of 50 patients (60%), the procedure was carried out with the patient under local anesthesia and conscious sedation, with the cryoprobe covering the lesion from an extraosseous position, avoiding direct penetration of the nidus. Clinical and radiologic features, procedure-related data, visual analog scale (VAS) pain scores, complications, and overall success rate were evaluated. Statistical analyses were performed by using the nonparametric Friedman test and Wilcoxon signed rank test for repeated measures. Results Fifty patients (median age, 24 years; interquartile range [IQR], 19-38 years; 31 men) underwent CT-guided cryoablation for the treatment of osteoid osteoma, with a 96% (48 of 50 patients) overall clinical success rate. Of the two patients without clinical success, one patient had incomplete pain relief and the other experienced a recurrence of osteoid osteoma at 11 months, which was successfully treated with a second cryoablation procedure. The median VAS pain score was 8 (IQR, 7-8) before the procedure and 0 (IQR, 0-1; < .001) after the procedure at both primary (6 weeks) and secondary (18-90 months) follow-up. Three of the 50 patients had minor complications (6%); no major complications were reported. Conclusion Osteoid osteoma was safely, effectively, and durably treated with CT-guided percutaneous cryoablation. In the majority of patients, treatment could be performed without general anesthesia, with the cryosphere covering the nidus from an extraosseous position. © RSNA, 2021.

Review
Targeted cannulation of the nidus and subsequent thermal ablation is the basis of CT-guided radiofrequency ablation (RFA) of osteoid osteoma, which is considered nowadays as the treatment of choice. The majority of complications during this procedure are due to thermal injury of adjacent structures. Specific measures as per the anatomical location of osteoid osteoma can avoid the majority of complications. This article enlists the possible complications and their necessary precautions and remedies to avoid these complications during CT-guided radiofrequency ablation of osteoid osteoma.

Review
Osteoid osteoma is the third most common benign bone tumor, with well-known clinical presentation and radiological features. Although surgical excision has been the only therapeutic option for a long time, to date it has been replaced by minimally invasive techniques, which proved satisfactory success rates and low complication occurrence. Therefore, the purpose of this literature review was to describe the main updates of these recent procedures in the field of interventional radiology, with particular attention paid to the results of the leading studies relating to the efficacy, complications, and recurrence rate. Nevertheless, this study aimed to analyze the peculiarities of each reported technique, with specific focus on the possible improvements and pitfalls. Results proved that all mininvasive procedures boast a high success rate with slight number of complications and a low recurrence rate. Radiofrequency ablation is still considered the gold standard procedure for percutaneous treatment of osteoid osteoma, and it has the possibility to combine treatment with a biopsy. Interstitial laser ablation's advantages are the simplicity of use and a lower cost of the electrodes, while cryoablation allows real-time visualization of the ablated zone, increasing the treatment safety. Magnetic resonance-guided focused ultrasound surgery is the most innovative non-invasive procedure, with the unquestionable advantage to be radiation free.

Osteoid osteoma is considered the most common benign bone forming tumor accounting for 12% of all benign bone tumors. The carpus is a rare site for this tumor but quite a few cases were reported before. The lesion can be subperiosteal, cortical or medullary. Computed tomography scan is the gold standard diagnostic study, whereas magnetic resonance imaging can result in delaying the diagnosis as reported in the literature. Open excision with or without grafting was the technique of choice in most reviewed cases in the literature. In this paper we will illustrate a minimally invasive technique using wrist arthroscopy for an osteoid osteoma of hamate proximal pole. This minimally invasive arthroscopic technique provides a rapid recovery for patients with lesions that are accessible to wrist arthroscopy.

Review
BACKGROUND
Intra- and juxta-articular osteoid osteoma (OO) is rare and can result in irreversible joint damage. Recently, arthroscopic surgery is being used more and more to avoid complications associated with other treatment modalities.
METHODS
On October 13, 2019, we conducted a systematic review of the literature available in PubMed and EMBASE regarding the arthroscopic management of OO involving the joints of the upper extremity. Predetermined inclusion criteria were used to include any relevant article published on and before that date for further analysis. Treatment success rate and tumor recurrence rate were considered the primary outcomes in our analysis.
RESULTS
Out of 113 studies, 19 met our inclusion criteria. Of the 32 reported cases in these 19 articles, ten involved the shoulder joint, 19 involved the elbow joint and three involved the wrist joint. Overall treatment success rate was 93.8%. Tumor recurrence rate was 0.0%. No postoperative complications (0.0%) were reported among cases involving the shoulder joint. Two out of 24 (8.3%) patients with elbow OO failed arthroscopic treatment due to incomplete excision, and two (4%) experienced minor complications. Among the three cases of wrist OO, two (66.7%) patients had residual postoperative pain and decreased hand grip strength.
CONCLUSION
Arthroscopic management of OO of the upper extremity joints is highly successful and results in no tumor recurrence; however, there is a risk of incomplete resection in areas more difficult to access by arthroscopy.

BACKGROUND This retrospective study aims to compare the efficacy of computed tomography-guided percutaneous excision and radiofrequency ablation in the treatment of osteoid osteoma. MATERIAL AND METHODS We evaluated 40 patients with osteoid osteoma who underwent either percutaneous excision or radiofrequency ablation between 2012 and 2015. The cohort consisted of 10 female and 30 male patients, with a mean age of 15.1 years (range: 4-27 years) and a mean follow-up time of 19.02 months (range: 11-39 months). Percutaneous excision was performed in 20 patients, while radiofrequency ablation was performed in the remaining 20 patients. RESULTS The success rates of percutaneous excision and radiofrequency ablation were comparable, with unsuccessful outcomes observed in 10% and 5% of patients, respectively. The reasons for failure in the percutaneous excision group were attributed to a marking error and incomplete excision of the wide-based nidus. Complications were limited to pathological fracture (n=1) and deep infection (n=1) in the percutaneous excision group, while no complications were encountered in the radiofrequency ablation group. CONCLUSIONS Both percutaneous excision and radiofrequency ablation demonstrate high success rates in treating osteoid osteoma. However, radiofrequency ablation offers the advantage of a quicker return to daily activities without the need for activity restrictions or splints. While being a more cost-effective option, percutaneous excision should be considered cautiously to minimize potential complications.

IMPORTANCE
Osteoid osteomas are benign bony overgrowths that can occur in any region of the body. However, they have a predilection to occur in the craniofacial region. Because of the rarity of this entity, there is a lack of literature detailing the management and prognosis of craniofacial osteoid osteomas.
OBSERVATIONS
Craniofacial osteomas have a predilection to involve the paranasal sinuses, but can also be found within the jaw, skull base, and facial bones. Because of their slow-growing nature, craniofacial osteomas are often incidentally discovered on routine imaging or after they compress nearby structures or distort nearby anatomy. Osteoid osteomas of the face can be treated with resection via various approaches. Recent advancements describe minimally invasive endoscopic techniques and adjuvant therapy with radiofrequency ablation guided by cone biopsy computed tomography. Osteoid osteomas have an excellent prognosis with complete resection. They demonstrate a low incidence of recurrence when compared with other osteoblastic lesions of the craniofacial structures.
CONCLUSIONS AND RELEVANCE
Craniofacial osteoid osteomas remain a developing topic within the field of craniofacial surgery. Their removal may be trending toward minimally invasive techniques. However, all treatment modalities appear to result in improved cosmetic outcomes and low recurrence rates.

Review
PURPOSE
The purpose of this study is to develop an accessible step-wise management algorithm for the management of pediatric spinal osteoid osteomas (OOs) based on a systematic review of the published literature regarding the diagnostic evaluation, treatment, and outcomes following surgical resection.
METHODS
A systematic review of the literature was conducted on PubMed to locate English language studies reporting on the management of pediatric spinal OOs. Data extraction of clinical presentation, management strategies and imaging, and treatment outcomes were performed.
RESULTS
Ten studies reporting on 85 patients under the age of 18 years presenting with OOs were identified. Back pain was the most common presenting symptom, and scoliosis was described in 8 out of 10 studies, and radicular pain in 7 out of 10 studies. Diagnostic, intraoperative, and postoperative assessment included radiographs, computed tomography (CT) scans, magnetic resonance imaging (MRI), bone scans, and frozen section. Treatment options varied, including conservative management, open surgical resection with or without intraoperative imaging, and percutaneous image-guided treatment. All included studies described partial or complete resolution of pain in the immediate postoperative period.
CONCLUSIONS
The proposed algorithm provides a suggested framework for management of pediatric spinal OOs based on the available evidence (levels of evidence: 3, 4). This review of the literature indicated that a step-wise approach should be utilized in the management of pediatric spinal OOs.
