Osteopoikilosis (OPK) or osteopathia condensans disseminate or spotted bones is a benign osteosclerotic dysplasia of unknown origin. It is an inherited autosomal disorder. It is usually detected as a coincidental finding at radiographic examination. Both sexes are equally affected. The condition is usually asymptomatic. The most common localization of these lesions is in the phalanges of the ha...

In 16 cadaver humeroulnar joints, the distribution of subchondral mineralisation was assessed by CT osteoabsorptiometry and the position and size of the contact areas by polyether casting under loads of 10 N to 1280 N. Ulnas with separate olecranon and coronoid cartilaginous surfaces showed matching bicentric patterns of mineralisation. Under small loads there were separate contact areas on the...

Pegylated interferon remains the first line treatment for patients with hepatitis D virus and more than one year therapy may be necessary. Interferon a has the most extensive clinical application and is used for the treatment of chronic hepatitis B and D virus as well as HCV infections. The attachment of polyethylene glycol to interferon increases its half-life. Treatment with peg interferon is...

Elbow pain and injury in young athletes include both acute traumatic and chronic overuse injuries. The anatomy of the developing pediatric elbow and the rapid growth of youth sports have led to an increase in chronic repetitive stress elbow injuries in the pediatric population. These injuries occur mostly in overhead athletes, throwers, and gymnasts. Force dissipation during throwing or axial l...

OBJECTIVES The purpose of this study was to retrospectively characterize the sonographic appearance of partial-thickness distal triceps brachii tendon tears. METHODS After Institutional Review Board approval, sonographic records were searched for patients who had an unequivocal partial-thickness triceps tendon tear at surgery or magnetic resonance imaging. Sonograms were retrospectively chara...

A 62-year-old woman with long-standing limited scleroderma presented to the outpatient rheumatology clinic because of pain and discomfort of the nose. On physical examination a firm subcutaneous nodule was observed over the ridge of the nose (A). No other such nodule-like lesions were observed. The nature of this nodule was disclosed by plain radiographs, which clearly demonstrated a subcutaneo...

Compared with arthroscopic release, open release is more commonly used for the treatment of stiff elbow. Flexion is recovered by releasing posterior tethering soft-tissue structures and by removing anterior impingement between the coronoid and/or radial head and the distal humerus. Extension is improved by releasing anterior soft-tissue tethers and by removing impingement between the olecranon ...

We report the results in 24 consecutive patients treated from 1976 to 1991 for nonunion of olecranon fractures. Their mean age was 42 years, and the mean interval from fracture to treatment for nonunion was 19 months. Management was by rehabilitation and activity as tolerated for three, continued immobilisation for one, and operative treatment for 20. Operations included excision of the olecran...

The diagnosis of nonunion was made by the presence of the clinical (pain, deformity, instability)and radiological signs of nonunion more than 4 months after the initial injury. Three patientshad developed infection and four of them had bone resorption after their initial treatments, whichprobably caused nonunion. Olecranon bone grafting combined with Kirschner wire fixation wasdone in all patie...
