Evaluation of vertebral bone mineral density in scoliosis by using quantitative computed tomography

Purpose: Scoliosis is described as a lateral curvature of the spine. We aimed to evaluate bone mineral density (BMD) in patients with scoliosis by using quantitative computed tomography (QCT) and compare the BMD of idiopathic and congenital scoliosis patients. Material and methods: Forty-three patients aged 1 to 40 years with idiopathic, congenital, or neuromuscular scoliosis and 41 matched controls of the same sex and approximate age were included in the study. Measurements of BMD were performed by QCT analysis for each vertebral body from T12 to L5, and mean BMD was calculated for each case. Results: Twenty-two of the patients with scoliosis were idiopathic, 15 were congenital, four were neuromuscular, and two were neurofibromatosis. The mean BMD values of patients with scoliosis were significantly lower compared with the control group (106.8 ± 33.4 mg/cm3 vs. 124.9 ± 29.1 mg/cm3, p = 0.009). No significant difference in BMD values was found between idiopathic and congenital scoliosis patients (p > 0.05). Conclusions: This study illustrated that the vertebral body BMD values of the patients with scoliosis were significantly lower than those seen in the control group

Cervical digits: a report of 3 cases

The occurence of digit like structures around vertebral column is a rare and only one case in the cervical region has been reported before. Here we report three more cases of cervical digits with computed tomography and magnetic resonance imaging correlations as the first cases of the literature

Cholelithiasis in cervico‐oculo‐acoustic (Wildervanck's) syndrome

An unusual case of cholelithiasis in an 18–month‐old boy with cervico‐oculo‐acoustic (Wildervanck's) syndrome is presented. Our patient had Duane's retraction syndrome, Klippel‐Feil anomaly and congenital deafness. To our knowledge this is the first case in which a probable association between cholelithiasis and Wildervanck's syndrome has been recorded. On the other hand, the presence of mutual malformations and anomalies such as scoliosis, ventricular septal defect, ectopic kidney, hydrocephalus, hypoplastic thumb and growth retardation seems to suggest that Wildervanck's syndrome is a clinical variant of Klippel‐Feil sequence.

Early and long-term changes in adjacent vertebral body bone mineral density determined by quantitative computed tomography after posterolateral fusion with transpedicular screw fixation

Objective: The aim of this study is to investigate vertebral body bone mineral density (BMD) changes following posterolateral fusion with transpedicular screw fixation using quantitative computerized tomography (QCT) in short and relatively long-term periods

Scapholunate dissociation associated with distal radius fractures

Objective: The exact prevalence of scapholunate dissociation (SLD) associated with distal radius fracture (DRF) and the effect of persistent SLD on the function of the wrist are not known. So, we examined the association between SLD and DRF and the effects of treatment on clinical outcomes. Methods: Eight hundred and twenty-nine patients with 839 DRF were included in the study. The radiographs of the patients were examined with special reference to SLD both in pre- and post-reduction period. Persistent SLD cases were evaluated by the scoring system of Green and O'Brien at least 2 years after the fracture. Results: Of the 839 fractures, 215 had SLD after the injury. When post-reduction radiographs were examined, SLD persisted in 98, but in 14 SLD was detected in the post-reduction period while not apparent in initial radiographs. So, a total of 112 patients (13.4 %) had persistent SLD. Nineteen patients were lost to follow-up and remaining 93 wrists examined clinically. Seventy-nine had pain on the scapholunate joint and 14 had not. When these patients were evaluated by Green and O'Brien system, symptomatic patients had fair or poor results but asymptomatic had good. The association between DRF and SLD is 13.4 %. Conclusions: Severity of the distal radius fractures is not associated with SLD. Intra-articular fractures were associated with significant increase in the prevalence of SLD. In some cases, SLD may appear after reduction in distal radius. Most cases with SLD are symptomatic, and this may be the reason of poor cases following distal radius fracture. © 2012 Springer-Verlag France

Evaluation of thyroid function status among postmenopausal women with and without osteoporosis

Objective: To investigate the relationship between thyroid function status and bone mineral density (BMD) among women with postmenopausal osteoporosis. Methods: A retrospective study was performed among 1217 women aged 45-80 years who attended the Department of Obstetrics and Gynecology at Dokuz Eylul University, Izmir, Turkey, between August 1, 2009, and June 1, 2013. Eligible participants were grouped according to the presence or absence of osteoporosis as defined by BMD measurements at the lumbar vertebrae (Ll-L4), femoral neck, or trochanter of the femur. Serum levels of free tri-iodothyronine, free tetraiodothyronine, and thyroid-stimulating hormone (TSH) were assessed. Results: The 303 women with osteoporosis had a lower mean TSH level (1.8 mIU/L) than did the 914 women without osteoporosis (1.9 mIU/L; P = 0.01). A positive correlation between TSH level and measures of BMD was observed (P = 0.01). The TSH level was associated with a protective effect in a regression model for development of osteoporosis; the odds ratio was 0.68 (95% confidence interval 0.53-0.86). Conclusion: Osteoporosis appeared to be independently associated with serum TSH level. Maintaining TSH levels within the upper limit of the reference range during treatment of hypothyroidism could be important to prevent osteoporosis among postmenopausal women.

To Compare the Diagnostic Consistency of Shoulder MRI and Shoulder US after Rotator Cuff Repair

Objective: Ultrasonography (US) and magnetic resonance imaging (MRI) are widely used radiological methods for the evaluation of the rotator cuff. Our purpose is to compare the accuracy of US and MRI in the diagnosis of rotator cuff injuries that underwent shoulder surgery
