High prevalence of rotator cuff tears in a population who never sought for shoulder problems: a clinical, ultrasonographic and radiographic screening study.

Background: This study was designed to investigate the prevalence of rotator cuff tears in a population who had never sought for symptoms from their shoulders. The aim was to see whether there is a correlation between dysfunction and the presence of cuff tears seen with ultrasonography or radiology.

Materials And Methods: Clinical assessment with constant score, ultrasound and radiographic examination was done on 106 voluntary subjects (212 shoulders).

Comparison of the uncemented Cone and the cemented Bimetric hip prosthesis in young patients with osteoarthritis: an RSA, clinical and radiographic study.

Background: There is no consensus as to whether uncemented or cemented femoral stems should be used in younger patients. We compared the uncemented Cone stem to the cemented Bimetric stem in young patients with osteoarthritis.

Patients And Methods: We randomized 45 relatively young patients (< 65 years old, mean age 54 years) with osteoarthritis to either an uncemented Cone stem or a cemented Bimetric stem.
