“…It is difficult to diagnose and usually appears in adolescents or young adult men. MOT is frequently reported in the orthopedic literature Case Report (2,5,6) and is rarely found in the head or neck, including the masticatory muscle (6,7). Here, we report a case of MOT involving the medial pterygoid muscle which had developed as a postoperative complication of endodontic treatment.…”

“…Myositis ossificans traumatica (MOT) also called traumatic myositis ossificans, myositis ossificans circumscripta (1,3), localized myositis ossificans, or fibrodysplasia ossificans circumscripta, is characterized by heterotopic bone formation within a muscle due to a single or repetitive injury (1,2,(4)(5)(6). The lesions are localized predominantly in the high-risk sites of injury (4).…”

“…Myositis ossificans of the head and neck region is more commonly found in the masseteric, 3 temporalis, 5,9 buccinator, 10 pterygoideus, 11 sternomastoid 12 and rarely in the scaleneus medius 13 muscles. The case reported here was found in an unusual location; the orbital plate of the frontal bone.…”

Myositis ossificans circumscripta is a pathological condition characterized by formation of bony tissue within the skeletal muscles following repeated trauma. A case of myositis ossificans circumscripta of the supra-orbital region in a 25-year-old man is presented and the pertinent literature is reviewed. To the best our knowledge this benign lesion has not been reported previously in the orbital region the world literature. Clinically the patient presented with a swelling and proptosis of the right eye. Radiologically there was a rounded opacity with well defined margin. Lesion was initially misdiagnosed as a fibroosseous lesion; however microscopic examination indicated matured myositis ossificans. Lesion was excised via a bicoronal flap. Careful clinical, radiological and pathologic evaluation is required to make this uncommon diagnosis in an unusual location such as the supra-orbital region to avoid unnecessary surgical mutilation of the patient. Key words: Myositis ossificans, supraorbital RésuméLa Myosite circumscripta ossificane est un état pathologique caractérisé par la formation de tissu osseux dans le muscle squelettique à la suite des traumatismes répétés. Un cas de la myosite circumscripta ossificane de la région supra orbitale chez un homme âgé de 25 ans est ici présenté et aussi la pertinence de la littérature est révisée. A notre connaissance, cette lésion bénigne n'a pas été signalée précédemment dans la région orbitale de la littérature du monde. Cliniquement le patient s'est présenté atteint du gonflement et du propose de l'oeil droit. Radiologiquement, il y avait une opacité arrondie avec des marges bien définies. Lésion a été au départ mal diagnostiqué comme une fibro-lésion osseuse ; toutefois, l'examen microscopique avait indiqué la myosite ossification mûre. Lésion a été excisée par l'intermédiaire d'un bicoronal flap. Prise en charge clinique, radiologique et évaluation pathologique est nécessaire pour faire ce diagnostique rare dans une situation inhabituelle telle que la région supra orbitale afin d'éviter les mutilations chirurgicales évitable chez le patient Mots clés Myosite ossificane, supra orbitale

“…Now, heterotopic ossification around the hip is a well-recognized complication of spinal cord injury, the incidence of which is routinely reported to be 15% to 20% (2). Proposed theories for the development of these various forms of MO include implantation of periosteum into the muscle, escape of osteogenic cells from the periosteum, ossification of a hematoma and metaplasia of connective tissue cells (3). Men and women are equally affected, and 75% are younger than 30 years of age.…”

Myositis ossificans (MO) is a benign, progressive, ossifying lesion that displays a characteristic zonal histological appearance. MO traumatica is a localized form of heterotopic bone formation, associated with repetitive micro-and/or macrotrauma in the majority of cases. The importance of imaging to differentiate MO from sarcomatous change and to determine maturity of the lesion is identified because suboptimal operative intervention on immature MO inevitably results in recurrence. A severe case of MO in a 24-year-old paraplegic man with chronic bilateral greater trochanteric pressure sores is presented, and the importance of the MO in the etiology and treatment of this case is discussed. An extensive review of the literature is included and integrated.Key Words: Heterotopic ossification; Myositis ossificans; Paraplegic; Pressure sore Myosite ossifiante sévère chez un polytraumatisé paraplégique : Influence du traitement des escarres de décubitus La myosite ossifiante (MO) est une lésion progressive bénigne caractérisée par son aspect histologique circonscrit. La MO traumatique est une forme localisée de formation osseuse hétérotopique associée à un microet/ou macrotraumatisme dans la majorité des cas. L'importance de l'imagerie pour différencier la MO d'une lésion sarcomateuse et pour déter-miner la maturité de la lésion est à souligner puisqu'une intervention chirurgicale stratégique suboptimale sur une MO immature entraîne inévitablement la récurrence. Un cas sévère de MO chez un paraplégique de 24 ans présentant des escarres de décubitus trochantériennes bilatérales chroniques est présenté ici. On aborde en outre l'importance de la MO dans l'étiologie et le traitement de ce cas. L'article propose aussi une revue complète de la littérature.A 24-year-old trauma patient, paraplegic secondary to a gunshot wound at the T5 level, was referred to the Plastic Surgery Division of the McGill University Hospital Center with grade IV bilateral trochanteric pressure sores. During the investigation, the presence of severe, left-sided pelvic myositis ossificans (MO) resulting in a fixed flexion contracture of the hip was noted. The patient had severe pain and spasm on leg extension and was unable to sleep or rest in a supine position. The radiological findings were consistent with MO. It was clear that this underlying problem had to be addressed simultaneously to provide definitive treatment of the trochanteric pressure sores. A review of the literature and details of the investigation of this specific case are provided.
