A relationship between haemophilia and osteoporosis has been suggested, leading to the initiative for a larger study assessing this issue. Bone mineral density (BMD) was measured by osteodensitometry using dual energy X-ray absorptiometry (DEXA) in 62 male patients with severe haemophilia A; mean age 41 +/- 13.1 years, mean body mass index (BMI) 23.5 +/-(More)
BACKGROUND Severity of vertical impact to the coccyx can range from mere contusion to a dislocated fracture of the coccyx. With early conservative management, most patients have a good prognosis and heal within weeks to months after the initial trauma. Occasionally, persisting symptoms make a surgical intervention with coccygectomy necessary. METHODS We(More)
OBJECTIVE To evaluate three-dimensional sonographic measurements of the thoracolumbar spine in the 16-37 week fetus. DESIGN Prospective cross-sectional study. SUBJECTS Two hundred and eighty-nine patients between 16 and 37 weeks of gestation were enrolled at the time of their anomaly scan or routine third trimester scan if fetal size was appropriate for(More)
The diagnosis of chronic lesions of the rotator cuff is challenging. We have developed a new index to improve the sonographic diagnosis of chronic tears of the cuff. In a pilot study, we examined 50 asymptomatic healthy volunteers by ultrasound to establish the diameter of the rotator cuff in relation to the tendon of the long head of biceps. Subsequently,(More)
PURPOSE It has been shown that intravenous administration of contrast media produces an MR arthrographic effect without the need for intraarticular injection. This is the first study evaluating this new technique of indirect MR arthrography in the diagnosis of glenoid labrum tears. METHODS 28 patients with clinically suspected labral injuries were(More)
PURPOSE Clinical and radiological evaluation of labral tears remains challenging. It has been shown that intravenous administration of contrast agents produces an MR arthrographic effect without the need for intraarticular injection. This is the first study evaluating this new technique of indirect MR arthrography in diagnosis of glenoid labrum tears. (More)
We report on a 27-year-old male Caucasian with severe haemophilia A who presented with acute onset of neck pain with cervical nerve root irritation, due to a spinal epidural haematoma. His past medical history revealed carrying of a moderate weight as a possible traumatic mechanism. Under immediate factor VIII replacement therapy complete remission of the(More)
AIM To determine the effect of different cage geometries and posterior instrumentation on the sagittal spinal profile after monosegmental lumbar interbody fusion. METHOD The study is based on a retrospective analysis of 119 patients with segmental instability, who were surgically managed by monosegmental PLIF with PEEK-Cages and dorsal instrumentation. (More)
We report a series of 108 elective orthopedic surgical procedures in hemophilia patients with inhibitors, comprising 88 cases in which radiosynoviorthesis was performed and 20 cases in which major orthopedic procedures were carried out. Hemostatic cover was provided by recombinant factor VIIa (rFVIIa, NovoSeven(R), Novo Nordisk, Bagsvaerd, Denmark) in 17(More)
AIM How well do ultrasound- and MRI-results after rotator cuff reconstruction correlate with postoperative clinical findings? METHODS Ultrasound- and MR-imaging of the afflicted shoulder on 40 patients who were surgically managed for isolated tear of the tendon of supraspinatus was performed at least 24 months after intervention. Patients were also(More)
