Abstract

Aim: To investigate the relationship between osteoporosis and demographic features, clinical characteristics,risk factors in younger SCI patients. Materials and Methods: Between January-June 2009, all SCI patients admitted to our hospital evaluated and 58 patients who were younger than 50 years who had osteoporosis were enrolled.Patients age, gender, educational status, duration of injury, smoking, sunlight exposure and dietary habits were questioned. Neurological level, completeness, ambulation status and spasticity were assessed. Relationship between these findings with the severity of osteoporosis has been viewed. Results: There were 19 women. Mean age was 35,7 years. The mean time since injury were 117.7 months. 42 patients were paraplegia (17 complete), 16 were tetraplegia (4 complete).The most common osteoporotic site where the legs. There was no correlation between BMD values with age. In men, the legs and total body BMD were significantly lower.The effect of educational level on BMD was not found. No significant correlation was found between time since injury and BMD. In paraplegics, femoral neck and total femur Z-scores were significantly lower. In tetraplegics, Z scores of the arms were lower, but was not significant. Lumbar BMD values of complete patients were significantly lower than incompletes. Sunlight exposure and consumption of milk/milk products had not a significant positive effect on BMD. 8 patients had therapeutic ambulation, whereas 23 of them had community ambulation. Ambulation status of patients and the presence of spasticity was no effect on BMD. There was no significant correlation between BMD and the severity of spasticity. Smokers (n=19), bone density was lower in all regions except for femoral neck but were not significantly. Conclusion: Male gender, paraplegia, and incompleteness negatively effects the bone density. Age, time since injury, education level, spasticity, ambulation level, smoking, sunlight exposure and dietary habits has no significant effect on bone density.

Özet

Amaç: Osteoporoz medulla spinalis yaralanması (MSY) sonrası görülen komplikasyonlardan biridir ve önemli morbidite nedenlerindendir. Bu çalışmada osteoporozu olan MSYli hastaların demografik özelliklerinin, klinik özelliklerinin ve mevcut risk faktörlerinin osteoporozla ilişkisinin incelenmesi amaçlandı. Gereç ve Yöntemler: Ocak 2009-Haziran 2009 tarihleri arasında hastanemizin MSY takip polikliniklerine başvuran veya rehabilitasyon amacıyla servise yatışı yapılan MSYli hastalardan son 1 yıl içinde çekilmiş mevcut DXA’larında osteoporoz bulunan veya başvuru sonrasında çekilen DXA’larında osteoporoz saptanan 50 yaş altındaki 58 hasta çalışmaya alındı. Bu hastaların yaş, cinsiyet, eğitim durumu, yaralanma süresi ve etiyolojisi, sigara kullanımı, güneş ışığına maruziyeti ve beslenme alışkanlıkları sorgulandı. Nörolojik seviyeleri, komplet mi /inkomplet mi oldukları, ambulasyon durumları ve spastisite varlığı ve şiddeti değerlendirildi. İstatistiksel analizde tanımlayıcı istatistiksel metodlar,Spearman korelasyon testi, Bağımsız Örneklem T Testi, Kruskal Wallis testi, Mann whitney U testi kullanıldı. Anlamlılık p
