Abstract
Back pain is a relatively common complaint in children and adolescents. The pediatric patient presenting with back pain can often be challenging, and there are many well-known organic diagnoses that should not be missed. In younger children, an organic cause of back pain can often be found. However, back pain in older children and adolescents is often "non-specific." The differential diagnosis of back pain in children includes neoplasms, developmental, and inflammatory conditions. Basic steps should include an in-depth anamnesis, a systematic physical examination, and standard spine radiographs (anteroposterior and lateral). Nevertheless, advanced diagnostic imaging and laboratory studies should be included when indicated to avoid missing or delaying a serious diagnosis. If other types of imaging tests are necessary (magnetic resonance imaging, computed tomography, bone scan, or single photon emission computed tomography), they should be guided by diagnostic suspicion.

Abstract
AIM CT-guided radiofrequency ablation (RFA) is among the thermal ablative procedures and provides great benefits with a minimally invasive procedure. In this prospective study, we aimed to reveal the significance of a multidisciplinary method in reducing the recurrence and complications in osteoid osteoma patients with CT-guided RFA performed by a team of experts in the field. MATERIALS AND METHODS A total of consecutive 40 patients with osteoid osteoma were prospectively evaluated and treated with CT-guided RFA. Before and the post ablation the visual analog scale (VAS) and use of nonsteroidal anti-inflammatory drugs (NSAIDS) were compared. RESULTS Post-ablation VAS of the patients at the 1st week and 3rd month after the procedure decreased significantly (p < 0.01) compared to the pre-ablation. The frequency of NSAID use after the ablation decreased significantly (p < 0.01) compared to the pre-ablation time. The pre-procedure NSAID use of our patients included in the study was average 6.93 per week, the NSAID use in the 3rd month post-procedure controls was average 0.53 per week. Recurrence was detected in 4 of our patients, 36 patients had complete recovery. CONCLUSION Radiofrequency ablation is an effective treatment method in the management of osteoid osteomas. Radiofrequency ablation has low recurrence rates and provides rapid regression in patients' pain after treatment.

Abstract
Osteoid osteoma is a benign bone tumor commonly occurring in the diaphysis and metaphysis of long bones. Only a few cases were reported in the literature about the rare location of epiphyseal osteoid osteoma and all were treated surgically. Herein, we report a rare case of an epiphyseal tibial osteoid osteoma, in a 14-year-old boy, which was initially diagnosed by imaging and confirmed by histopathology. To the best of our knowledge, this is the first case of an epiphyseal osteoid osteoma treated successfully by CT-guided radiofrequency ablation in a pediatric patient with a good outcome and no detrimental effects. The case highlights the rarity of such presentation, the importance of early imaging and diagnosis, and the success of CT-guided radiofrequency ablation in the treatment of epiphyseal osteoid osteoma.

Abstract
Introduction Osteoid osteomas are the most frequent true benign bone tumor in the adolescent age group and the third most prevalent benign bone tumor overall. This study was designed to assess the effectiveness of the procedure and correlate it with the analgesia offered because of the significant burden of this illness and new literature supporting the successful outcomes of image-guided percutaneous radiofrequency ablation (RFA) in osteoid osteoma. Methodology This hospital-based interventional trial was carried out in a tertiary care referral center. Forty-two patients with osteoid osteoma, ranging in age from 9 to 30, were included in the study. The patients received RFA guided by computed tomography (CT), and they were postoperatively monitored at one, two, and four weeks and three, six months, and 12 months. A numerical pain scale (NPS) was used to evaluate the patient's pain both before and after the procedure. The preoperative and postoperative results were contrasted. Results A total of 42 participants were enrolled in the study. Eight (19.05%) women and 34 (80.95%) men made up the group. Complete pain alleviation (NPS=0) was attained in 42.8% and 96.4% of the study group in the first and second weeks post-procedure. Almost all patients began protected weight-bearing at one week, according to their level of pain tolerance. Osteoid osteoma of the talus was a remnant lesion in one patient that required further treatment after two weeks. During the duration of the follow-up, no problems were recorded. Conclusion Percutaneous CT-guided RFA of osteoid osteoma is a safe, minimally invasive procedure and greatly reduces the duration of hospitalization. It has excellent functional outcomes and no known complications.

Abstract
Back pain is common, in up to 30% of children, increasing with age. Eighty percent is benign, mechanical type, improving within 2 weeks of conservative care. Required for those not improving is in-depth evaluation, including MRI, laboratory, and peer consultations. Spondylolysis and spondylolisthesis comprise almost 10% of pediatric back pain, often caused by lumbar hyperextension activities and treated conservatively in most cases. Osteoid osteomas and osteoblastomas constitute the most common benign spinal tumors in childhood. Aggressive and malignant tumors of the spine are rare but when present require tertiary care referral and a comprehensive oncology team for optimal life-sustaining outcomes.

Abstract
Background Osteoid osteoma (OO) comprises approximately 11%-14% of benign bone tumors. The main symptom of OO is localized pain accompanied by nighttime aggravation. Surgical treatment is frequently used in clinic, including open surgery and percutaneous ablation, the latter including radiofrequency ablation, cryoablation, and microwave ablation, but there is no consensus on when and how to choose the best treatment for OO. Purpose We did a systematic review of the literature on existing surgical treatments of OO to assess the safety and efficacy of surgical treatments of OO and to evaluate the surgical options for different locations of OO. Methods The inclusion criteria in the literature are 1. Patients diagnosed with osteoid osteoma and treated surgically; 2. Include at least five patients; 3. Perioperative visual analogue scale (VAS), postoperative complications, and recurrence were recorded; 4. Literature available in PubMed from January 2014 to December 2021. Results In the cohort, 1565 patients (mainly adolescents) with OO received 1615 treatments. And there are 70 patients with postoperative recurrence and 93 patients with postoperative complications (minor: major=84:9). The results of Kruskal-Wallis examination of each experimental index in this experiment were clinical success rate H=14.818, p=0.002, postoperative short-term VAS score H=212.858, p<0.001, postoperative long-term VAS score H=122.290, p<0.001, complication rate H=102.799, p<0.001, recurrence rate H=17.655, p<0.001, the technical success rate was H=45.708, p<0.001, according to the test criteria of α=0.05, H0 was rejected. The overall means of the outcome index in each group were not completely equal. Conclusion Percutaneous ablation and open surgery are safe and reliable for OOs, and the technical success rate of percutaneous ablation is higher than that of open surgery. Open surgery and cryoablation can be selected for OOs close to the nerve and atypical sites, while radiofrequency ablation and microwave ablation can be selected for OOs in most other sites.

Abstract
PURPOSE To evaluate safety and efficacy of percutaneous ablative therapy for the treatment for osteoid osteomas. MATERIALS AND METHODS PubMed database, Web of Science, and SCOPUS were searched from their inception until November 2019 for articles describing osteoid osteoma. Demographic data, success rates, pre- and post-procedure VAS scores, and complications were recorded. A random-effects meta-analyses of the VAS pain score at various time points were calculated. RESULTS For radiofrequency ablation, VAS scores for pain at pre-procedure, 24-48 h, and 3-6 months yielded cumulative pain scores of 7.64 +/- 0.175, 0.78 +/- 0.186, and 0.02 +/- 0.0196, respectively. For cryoablation, VAS scores at pre-procedure, 24-48 h, and 3-6 months yielded cumulative pain scores of 8.46 +/- 0.549, 0.975 +/- 0.66, and 0.112 +/- 0.08, respectively. For laser ablation, VAS scores at pre-procedure and 24-48 h yielded cumulative pain scores of 4.94 +/- 1.42, and 0.506 +/- 0.268, respectively. For microwave ablation, VAS scores at pre-procedure, 24-48 h, and 3-6 months yielded cumulative pain scores of 6.14 +/- 1.07, 1.636 +/- 1.215, and 0 +/- 0.0, respectively. All ablation methods resulted in significant immediate and lasting pain reduction (p < 0.001). Technical and clinical success rates and major complications for RFA, microwave ablation, laser ablation, and cryoablation did not differ significantly. Overall recurrence of bone pain at the same site occurred in 4.06% of all patients an average of 11 months post-procedure. CONCLUSION Percutaneous ablative therapies are safe and result in significant and lasting pain reduction as demonstrated through visual analog scale pain scores.

Abstract
OBJECTIVE Osteoid osteomas are benign bone tumors commonly treated using thermal ablation. We compare the technical success, complication rates, and long-term efficacy of the two most common ablation types: radiofrequency and microwave. MATERIALS AND METHODS A retrospective study was performed of all osteoid osteoma ablation procedures between 2007 and 2017. A ten-point numerical pain scale was used to quantify symptoms before and after the procedures with > 12-month follow-up. Complications were reported using the Society of Interventional Radiology Adverse Events reporting criteria. RESULTS Twenty-nine patients successfully underwent 15 radiofrequency ablations and 15 microwave ablations with a technical success rate of 83% for radiofrequency and 100% for microwave (p = 0.23). Long-term recurrence rates (p = 1.0) and complication rates (p = 0.60) were not significantly different for the groups. One patient developed a skin burn following microwave ablation and another developed 12 months of sciatic neuropathy following radiofrequency ablation. CONCLUSION Microwave and radiofrequency ablation are safe and effective methods for treating osteoid osteomas with similar long-term efficacies. Although radiofrequency ablation is more commonly reported to result in skin burns, this complication can arise during microwave ablation.

Abstract
Osteoid osteoma is a painful benign bone tumour of children and young adults with characteristic clinico-radiological features depending upon the location of the lesion. Intraoperative visualisation of the nidus is difficult and therefore curative surgery is often associated with excessive bone removal, significant perioperative morbidity and potential need of bone grafting procedures. With advancement in cross-sectional imaging and radiofrequency ablation (RFA) technology, CT-guided RFA has emerged as the treatment of choice for the osteoid osteoma. This procedure involves accurate cannulation of the nidus and subsequent thermocoagulation-induced necrosis.Multidisciplinary management approach is the standard of care for patients with osteoid osteoma. Appropriate patient selection, identification of imaging pitfalls, pre-anaesthetic evaluation and a protocol-based interventional approach are the cornerstone for a favourable outcome. Comprehensive patient preparation with proper patient position and insulation is important to prevent complications. Use of spinal needle-guided placement of introducer needle, namely, "rail-road technique" is associated with fewer needle trajectory modifications, reduced radiation dose and patient morbidity and less intervention time. Certain other procedural modifications are employed in special situations, for example, intra-articular osteoid osteoma and osteoid osteoma of the subcutaneous bone in order to reduce complications. Treatment follow-up generally includes radiographic assessment and evaluation of pain score. Dynamic contrast-enhanced MRI has been recently found useful for demonstrating post-RFA healing.

Abstract
OBJECTIVES This study aims to present the importance of a multidisciplinary approach to radiofrequency ablation (RFA) treatment in osteoid osteoma (OO) patients by a team of experts in their field in preventing recurrence and complications. PATIENTS AND METHODS For this retrospective study, a team of two orthopedists, two interventional radiologists, and one anesthesiologist was established in January 2013 to manage the diagnosis, follow-up, and treatment process of patients with OO at Bakırköy Dr. Sadi Konuk Training and Research Hospital. A total of 27 patients (15 males, 12 females; mean age 22.9 years; range, 9 to 54 years) were treated by this team between February 2013 and September 2016. The anatomic localization included iliac crest in four patients, the femur in 12 patients, fibula in two patients, humerus in three patients, radius in one patient, tibia in three patients, talus in one patient, and metacarpal in one patient. The procedures were carried out by the same interventional radiologists, same orthopedic surgeons, and same anesthesiologist in the computed tomography (CT) unit under aseptic conditions. After appropriate anesthesia for the localization of OO, the patient was positioned on the CT bed and the localization of the lesion was confirmed with a CT scan mapping. Then, a bone penetration cannula was advanced and bone cortex was penetrated with a charged motor and Kirschner (K)-wire. When the cannula reached the nidus, it was replaced with RFA probe. Ablation of the nidus was performed for five minutes at 90°C. RESULTS The mean follow-up period was 46 months (range, 25 to 66 months). Patients were evaluated with visual analog scale (VAS) scores preoperatively and at postoperative 15th day, sixth month, and first year. In the last evaluation of the study data, the patients were called by telephone and questioned whether there were any changes in their final status. The mean preoperative VAS score was 7.2. The mean postoperative VAS scores of the 15th day, sixth month, and first year were 1.3, 0.6, and 0, respectively. In the last follow-up, the OO-related pain completely disappeared and none of the patients had any recurrence. There was a significant difference between preoperative and postoperative 15th day and sixth month VAS score measurements. CONCLUSION Radiofrequency ablation treatment of OOs is a minimally invasive, safe, low-cost, and efficient method. We believe that with experienced teams and appropriate planning, RFA will take part in practice as the standard treatment of OO.

Abstract
Objective The purpose of this study is to report our experience in using image-guided percutaneous radiofrequency ablation (RFA) for the treatment of osteoid osteoma (OO) and the subsequent duration of pain relief over a period of about six years (May 2013-March 2019; 70 months) at a tertiary-care hospital in a developing nation. Methods A retrospective study was performed at the radiology department of Aga Khan University, Karachi, Pakistan. All patients who had undergone image-guided percutaneous RFA for OO between May 2013-March 2019 were included. All cases had been performed with CT-guidance under general anesthesia, with an additional local anesthesia injection also administered to the patients. A soloist needle had been used for RFA. The primary success rates, complications, symptom-free intervals, and follow-ups were evaluated. Results In total, 15 patients (11 males, 4 females) of a mean age of 13.93 years (range: 5-25 years; median age: 14.5 years) with OO underwent image-guided percutaneous RFA during a period of 70 months. Eleven lesions were located in the femur, three in the tibia, and one in the humerus. The mean nidus size was 8.1 x 5.73 mm [range: (4.9-11.5) x (3.8-9.1) mm]. All patients were successfully treated and experienced resolution of pain in 2.36 months (range: 1-4 months). During the follow-up period (range: 3-40 months; mean: 13.85 months; median: nine months), none of the patients experienced any relapse or persistent symptoms. No major complications were reported. Conclusion Image-guided percutaneous RFA is a minimally invasive and safe treatment option with high efficiency and a high rate of technical success for the treatment of OO. The risk of recurrence is remote with all patients achieving independent recovery.

Abstract
Objective: Osteoid osteoma, which is observed in the adolescent and young adult population as benign bone tumors, appears as a single nidus with a diameter < 2 cm and is treated with open surgery. However, technological advances in medicine have made it possible to apply less invasive procedures in surgery. Methods: Between 2006–2014, 24 patients < 18 years of age were treated for osteoid osteoma. Patient demographic data, surgical data, complications, and recurrences were noted. Results: Twenty-four patients (mean age, 11 [2–18] years) were treated and followed up for a mean 3.58 (range, 1–9) years. Mean patient age in the curettage group was 12.1 (range, 3–18) years. Mean operation length was 69.5 (range, 60–120) minutes. Mean hospital stay was 1.3 (range, 0–2) days. Mean patient age in the radiofrequency ablation (RFA) group was 10.7 (range, 2–17) years. Five patients were female and 8 were male. Mean operation length was 49.6 (range, 20–90) minutes. Mean hospital stay was 0.3 (range, 0–1) days. Mean follow-up time was 1.76 (range, 1–4) years. Mean operation length, hospital stay, and follow-up were significantly shorter in the RFA group. Conclusions: Considering reduced costs due to shorter hospitalization periods and the ability to reach anatomically difficult locations, percutaneous procedures are likely to replace the conventional open approach. Level of evidence: II, retrospective study.

Abstract
An osteoid osteoma is a benign bone tumor that arises from osteoblastic dysfunction and usually presents as nonspecific, nocturnal pain located in the diaphysis of long bones, with <1% occurring in the ribs. It is most commonly treated with nonsteroidal anti-inflammatory drugs or merely observed; when these treatments do no prove efficacious, either open surgery or interventional ablation are pursued. Herein, we report a rare case of an osteoid osteoma located in the rib of a 19-year-old male that was histologically diagnosed through computed tomography (CT)-guided biopsy. Using CT guidance, the tumor was ablated by creating an artificial pneumothorax in order to induce a margin of space safe enough for cryoablation. It is important to be aware of the possibility that an osteoid osteoma may be present in the ribs, as the differential diagnosis includes costochondritis, pneumonia, osteoblastoma, enchondroma, osteosarcoma, cyst, and Brodie abscess. In addition, we have shown that CT-guided cryoablation can be an effective and less invasive treatment when compared to open en bloc resection, highlighting the role of interventional radiology in bone tumor ablation.

Abstract
Osteoid osteomas are well known for intraoperative technical difficulties for localization and adequate excision, especially when they are not clearly visualized on plain radiographs or when they occur in difficult and inaccessible situations. Localization in the radiology suite and shifting the patient to the operating room can be cumbersome, and can result in errors because of lack of real-time imaging. In these scenarios, intraoperative navigation will be useful. We report a technique of intraoperative computed tomography (CT) navigation for localization and excision of osteoid osteomas of the long bones. Six patients (four femoral and two tibial lesions) with a radiological diagnosis of osteoid osteoma, in whom the nidus could not be visualized clearly on plain radiographs, were treated with this technique. Intraoperative CT navigation with AIRO was performed and the images were registered to the computer. The lesion was then localized and excised using a high-speed burr. All patients underwent postexcision on-table CT scans, which showed complete excision of the nidus. All patients became symptom free and are doing well at a minimum follow-up of 6 months. Intraoperative CT navigation helps to exactly localize the nidus and also helps to confirm complete excision of the nidus. This is a safe, effective and minimally invasive method to treat osteoid osteomas, particularly those that are not amenable to excision under C arm guidance.

Abstract
Osteoid osteoma is a benign bone neoplasm with a reported incidence of 2-3% among all bone primary tumors. Although it is a small and benign lesion, it is often cause of patient complaint and discomfort. It is generally characterized by a long lasting, unremitting pain that typically exacerbates at night, often leading to sleep deprivation and functional limitation of the skeletal segment involved, with a significant reduction of patient daily life activities and consequent worsening of the overall quality of life. Over decades, complete surgical resection has represented the only curative treatment for symptomatic patients. In the last years, new percutaneous ablation techniques, especially radiofrequency ablation, have been reported to be a safe and effective alternative to classical surgery, with a low complication and recurrence rate, and a significant reduction in hospitalization cost and duration. The aim of this article is to provide an overview about the radiofrequency thermal ablation procedure in the treatment of osteoid osteoma. (www.actabiomedica.it)

Abstract
Osteoid osteoma accounts for approximately 10-12% of all benign bone tumors. Surgery was the treatment of choice for osteoid osteomas until percutaneous radiofrequency ablation (RFA) was introduced in 1992. Although RFA is generally considered curative in the treatment of osteoid osteoma, disease recurrence after ablation has been reported. We report a case in which RFA was delayed by the presence air surrounding the ablation probe. In this case, ablation could only be performed after the probe was removed and saline was injected through the introducer needle to displace the air. Air is reported to decrease radiofrequency energy transmission; a simple measure like injecting saline through an introducer could prevent such a complication. We also suggest that partial air in the ablation bed surrounding the ablation probe could decrease the energy transmission and may be one of the causes of early recurrences. Saline injection could be helpful in providing a more reliable environment for ablation.

Abstract
Osteoid osteoma is a rare clinical entity often mistaken for osteomyelitis, enchondroma, osteochondroma and other bony pathologies. Cardinal features include localized swelling and nocturnal pain often relieved by nonsteroidal antiinflammatory drugs. Definitive treatment requires surgical removal of the lesion by curettage or en bloc excision. The following case report details the diagnosis and management of a recurrent case of osteoid osteoma in a long finger proximal phalanx. Included with this case report is a literature review of osteoid osteomas on the hand and the anatomic distribution of 289 cases published in the last 30 years.

Abstract
OBJECTIVE To evaluate the clinical outcomes of open surgery for osteoid osteoma with three-dimensional (3-D) C-arm scan under the guidance of computer navigation. METHODS The clinical data of 14 patients who had undergone 3-D C-arm scan under the guidance of computer navigation during open surgery for osteoid osteoma from March 2012 to June 2015 were analyzed retrospectively. There were nine male and five female subjects aged from 9 to 55 years (mean, 26 years). Eight of the tumors were located in the femur, four in the tibia, one in the humerus and one in the scapula. Preoperative pain visual analogue scale (VAS) scores ranged from 2 to 6 (mean ± SD, 4.7 ± 1.1). Conventional surgical approaches were used to expose the tumor surfaces depending on their locations. Involved regions were scanned by 3-D C-arm fluoroscopy during the procedure and then the tumors were accurately located and their niduses removed under the guidance of computer navigation. Afterwards, repeat 3-D C-arm scans of the surgical region were performed to confirm tumor eradication. None of the patients received postoperative intravenous analgesia. Eight patients received oral non-steroidal anti-inflammatory drugs on the day of surgery, these drugs being discontinued on the second postoperative day. Postoperative pathological diagnoses were recorded. At the follow-up visits, imaging and VAS scores were obtained to evaluate the therapeutic effect and any evidence of recurrence. RESULTS All the patients successfully underwent computer navigation-guided surgery. The duration of surgery ranged from 60 to 135 min (mean, 94 min) and the amount of bleeding from 50 to 150 mL (mean, 80 mL). None of the patients needed bone grafting or internal fixation. No complications were seen. All patients were followed up for 4 to 36 months (mean, 16 months). Postoperative pathological diagnoses of osteoid osteoma were made in 12 patients; thus, the rate of pathologically confirmed diagnosis was 86%. VAS scores decrease to an average of 1.4 ± 0.6 3 days after surgery and were zero for all patients 4 months after surgery. No tumor recurrence was found by X-ray or CT scan examination during follow-up. CONCLUSIONS The niduses of osteoid osteomas can be eradicated by open surgery with 3-D C-arm scan under the guidance of computer navigation with minimal damage to bone structure and a high rate of pathologically confirmed diagnoses.

Abstract
Background The aim of this retrospective study is to determine our experience of technique success rate, complications and clinical results in long term follow up for computed tomography (CT)-guided radiofrequency ablation [RA] therapy for osteoid osteoma (OO). Material/Methods We performed RA therapy to 18 patients with OO referred to interventional radiology from other clinics primarily from orthopedics; between January 2011 to May 2014. Daytime and nighttime pain intensity of 18 patients was noted according to visual analog scale (VAS). After procedure pain intensity was compared with before one. We also discussed other factors can affect it. Results All procedures were completed technically successful for all patients [100%]. We did not experience any major complication or mortality. However we had 3 minor complications. Pain came back in 1 patient after 5 months from procedure and it was considered as recurrence. Dramatic pain intensity fall was seen in patients after procedure, both daytime and nighttime. However we did not find and statistically significant change in comparison of pain intensity reduce and time needed to return back to routine life when using patients demographic data and lesion size. Conclusions CT guided RA therapy of OO is minimally invasive, effective and secure procedure.

Abstract
BACKGROUND An osteoid osteoma is a benign bone tumor that tends to be <1 cm in size. The tumor is characterized by night-time pain that may be relieved by aspirin or other non-steroidal anti-inflammatory drugs. Osteoid osteoma can be treated with various conservative and surgical methods, but these have some risks and difficulties. The purpose of the present study was to present an alternative treatment method for osteoid osteoma and the results we obtained. MATERIAL AND METHODS In the period from 2010 to 2014, 10 patients with osteoid osteoma underwent nidus excision by using a safe alternative method in an operating room (OR) with no computed tomography (CT). The localization of the tumor was determined by use of a CT-guided Kirschner wire in the radiology unit, then, in the OR the surgical intervention was performed without removing the Kirschner wire. RESULTS Following the alternative intervention, all the patients were completely relieved of pain. In the follow-up, no recurrence or complication occurred. CONCLUSIONS The presented alternative method for treating osteoid osteoma is an efficient and practical procedure for surgeons working in clinics that lack specialized equipment.

Abstract
PURPOSE The aim of this study was to compare CT-assisted percutaneous excision, which is a closed, economic method and a more cosmetic approach, and open surgery in the treatment of osteoid osteoma. MATERIALS AND METHODS Fifty-three patients (12 female and 41 male patients) who had percutaneous excision (n = 24) and open surgery (n = 29) were evaluated retrospectively. The mean age was 16.6 years and the mean duration of follow-up was 53.5 months. During percutaneous excision, a trephine was advanced through the labeling wire and the site, including the nidus, was excised en-bloc and the incision walls were curetted. During the open surgery, the localization of the nidus was marked using c-arm X-ray and the nidus was accessed by lifting the cortical bone, layer-by-layer, using burr. The nidus was excised and its cavity curetted. RESULTS The result was successful in 22 and a failure in three patients who had closed excision. The result was successful in 20 and a failure in nine patients who had open surgery. The mean duration of operation was 44.37 minutes in the percutaneous excision group and 80.6 minutes in the open surgery group. There was no difference in the pre-operative VAS values between the two groups, whereas the post-operative VAS values were statistically significantly different. There was also a statistically significant difference in the duration of the operation and the length of the hospital stay between the groups. CONCLUSION Percutaneous excision with trephine is a more successful, effective, minimally invasive, safe and a better cosmetic approach in the treatment of osteoid osteoma. This method is also a cheap method that does not require expensive equipment.
