Traumatic myositis ossificans as a result of college fraternity hazing.

ABSTRACT: We present a case of a 20-year-old college student who had myositis ossificans traumatica develop after a fraternity hazing. The patient was struck repeatedly on both of his thighs while standing at attention, and he presented with bilateral thigh pain and stiffness 6 weeks after the incident. Physical examination revealed 130 degrees flexion of his right knee and 50 degrees flexion of his left knee, which had a firm end point. Radiographs showed extensive new bone located adjacent to the anterior and lateral aspects of his left femur with less involvement of his right thigh. Magnetic resonance imaging revealed considerable edema involving much of the rectus femoris and vastus lateralis of both thighs. The patient was treated with physical therapy and indomethacin for pain and inflammation control. At his 1.5-year followup, the patient's left knee flexion had improved to 130 degrees . Nonoperative treatment with careful followup resulted in a favorable outcome in this patient despite considerable formation of bilateral thigh myositis ossificans traumatica.

Project description:BACKGROUND:Myositis ossificans describes a heterotopic bone formation within a muscle. Thereby myositis ossificans is classified in two different groups: myositis ossificans progressiva (MOP) which describes a genetic autosomal dominant rare disease and myositis ossificans traumatica (MOT). The exact pathogenesis of MOT is unclear. The aim of this article was to analyse and interpret the existing literature reporting MOT of masticatory muscles and compare the results with our own clinical experience with MOT. Risk-factors, etiology, clinical features, diagnostic imaging, as well as different treatment options were evaluated and recommendations for the prevention, diagnosis, and therapy of MOT of the masticatory muscles were given. METHODS:Following the PRISMA-Guidelines, a systematic search within the PubMed/Medline database with a view to record literature of MOT of the masticatory muscles was performed. Furthermore, the database of our own clinic was screened for cases of MOT. RESULTS:In total, 63 cases of MOT of the masticatory muscles which were reported in English-based literature were included in this study. Overall, 25 female and 37 male patients could be analysed whereas one patient's gender was unknown. Complication of wisdom-tooth infection (n =?3) as well as the results of dental procedures like dental extraction (n =?7), mandibular nerve block (n =?4), periodontitis therapy (n =?1) were reported as MOT cases. From the 15 reported cases that appeared after dental treatment like extraction or local anesthesia the medial pterygoid (n =?10) was the most affected muscle. Hereof, females were more affected (n =?9) than males (n =?6). The most reported clinical symptom of MOT was trismus (n =?54), followed by swelling (n =?17) and pain (n =?13). One clinical case provided by the authors was detected. CONCLUSIONS:Dental procedures, such as local anesthesia or extractions, may cause MOT of the masticatory musculature. Demographical analyses demonstrate that females have a higher risk of developing MOT with respect to dental treatment. The most important treatment option is surgical excision. Subsequent physical therapy can have beneficial effects. Nevertheless, a benefit of interpositional materials and drugs as therapy of MOT of the masticatory muscles has not yet been proven. Myositis ossificans progressiva has to be excluded.

Project description:BackgroundEpidemiological studies show that most of the adult population will be exposed to at least one potentially traumatic event in the course of his/her life; adolescence and early adulthood are the most vulnerable periods of life for exposure to traumatic experiences (70% of their deaths are due to external causes). Posttraumatic Stress Disorder is characterized by the development of dysfunctional symptoms that cause distress or social, academic, or occupational impairment, as result of exposure to a traumatic event. The aim of this multicentric study is to establish the proportion of college students, within seven institutions in Northeastern Brazil, who were exposed to traumatic experience and met PTSD criteria.Methods/designA one-phase census protocol of seven college institutions in three metropolitan regions in Northeastern Brazil was performed (April to July 2011). All students aged 18 years or older, matriculated and attending their first or final semester were eligible. The self-applied protocol consisted of a socio-demographic questionnaire and the following scales adjusted to Brazilian Portuguese standards Trauma History Questionnaire (THQ), PTSD Checklist-Civilian (PCL-C), Impulsivity Scale (BIS-11). Data were entered into SPSS 17.0.Results2213 (85.5%) students consented to participate, and completely filled in the protocols. Of these, 66.1% were woman, mean age 23.9 (SD 6.3), 82.7% were single, and 57.3% attended university outside their native cities. The total PTSD prevalence was 14%, and the median for frequency of trauma exposure was 5 events.ConclusionA high frequency of exposure to violence, as well as a high rate of PTSD, suicide attempts, and high-risk sexual behavior was found in Brazilian college students. This highlights the importance of effective public health actions in relation to the prevention and treatment of PTSD and other dysfunctional behaviors resulting from traumatic exposure in young individuals, usually an at risk population for violence and traumatic situations.
