Osteoid Osteoma of the Coracoid Process Presenting as Adhesive Capsulitis in a 10-Year-Old Male: A Case Report

A 10-year-old male presented with symptoms in his right shoulder indicative of adhesive capsulitis. Radiographic films did not demonstrate any osseous abnormalities. Magnetic resonance imaging demonstrated the presence of an eccentric lesion within the coracoid process consistent with an osteoid osteoma. Six months after surgical removal the patient is back to full activities. For the pediatric population, surgeons must always consider diagnoses that could alter a patient's growth or result in long-term disability. In particular, an atypical presentation of musculoskeletal disease in a pediatric patient presenting with a disease that typically is seen in the older population warrants further workup.

Arthroscopic excision of an intra-articular osteoid osteoma in the elbow joint

An osteoid osteoma is a rare, small, benign and painful tumour occurring in the extra-articular portion of long bones seen most commonly in the lower extremities. This is a case report of a 23-year-old female patient who underwent arthroscopic resection of an intra-articular osteoid osteoma. The nidus was completely removed by arthroscopic excision. The diagnosis was confirmed by postoperative histopathological analysis. In the case presented we have shown that intra-articular arthroscopy can be successful in the surgical management of benign bony lesions involving the elbow joint. We also present a review of the literature which reports on similar cases or intra-articular disease, preferred methods of surgical management and limitations in histopathological specimen acquisition for diagnosis.

Arthroscopic Excision of Osteoid Osteoma of the Elbow

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.

L'ostéome ostéoïde de l'apophyse coronoïde est exceptionnel, pose des problèmes diagnostiques et thérapeutiques. La douleur représente le maître symptôme. La perte d'extension complète est classique, cependant celle de la pronation et supination est très rare. Le scanner constitue l'examen radiologique de référence à condition de réaliser des coupes fines. La résection monobloc à foyer ouvert constitue le traitement de référence. Les traitements percutanés sont aussi efficaces mais au coude la proximité des éléments vasculo-nerveux et du cartilage articulaire rendent leurs indications plus limitées.
