“…They had mentioned that neither of these was statistically significant. They also had mentioned that the normal ranges for both levels and sexes are therefore very similar; their findings differ from previously published data in which men appear to consistently have a greater degree of vertebral wedging than women [25] however our study is consistent with the study done by [25] The presented figures correlate between the age and the Cobb angle from T12 to L4. There were linear relationships, as the age increased the angle was decreased except for L4 it increases.By applying the following equation the L4 Cobb angle can be estimated:…”

Abstract:The aim of this study is to establish normal values as reference for vertebral end plate from T12 to L4 in normal Sudanese subjects using computerized tomography (CT).130 lateral scout CT scans done using GE Healthcare machine with KV120, MA10-50 for lumber vertebra were obtained from subjects (65 males and 65 females) their ages ranged from (15-74) years old .Endplates angle from T12 to L4 were measured using Cobb Method for both genders and the data were correlated to their ages. For males the endplates mean angles were found to be 7.4±3.5,6.6±3.3,4.7±2.9,5.3±3.8,18.8±7.6 and for females 9.2±4.5,9.9±4.5,9.7±4.2,6.8±4.3,5.9,4.6 for T12,L1,L2,L3and L4 respectively. The research also studied the difference according to gender; it showed significant difference at p value 0.05, the end plates angles were affected as the subjects ages increase. The study concluded that the mean Cobb angle end plate differs significantly from males and females Sudanese subjects and it has relation with age and the values differs from what was mentioned in the previous studies, the knowledge of the normal end plates angle allows better characterization and diagnosis for vertebra from T12 to L4.

High prevalence of osteoporosis in cardiac transplant recipients and discordance between biochemical turnover markers and bone histomorphometry

Osteoporosis and asymptomatic vertebral fractures are common following cardiac transplantation. Biochemical markers of bone turnover were increased in the majority of patients. Many had biochemical evidence of secondary hyperparathyroidism but this could be attributable to significant renal failure in only 50% of cases. Osteocalcin and alkaline phosphatase correlated inversely with bone density. Histomorphometric findings did not correlate with these biochemical changes in most cases. These results suggest that multiple factors are responsible for osteoporosis in cardiac transplant recipients. Osteocalcin and alkaline phosphatase may be useful biochemical markers, predicting patients at highest risk of fracture.
