Case ReportsVenous air embolism during knee arthrography. A case report.
A 34-year-old man developed a nonfatal venous air embolism during arthrography of his post-traumatically contractured knee joint. From the arthrographic findings, injected air was assumed to have entered the great saphenous vein via the venous opening in the knee joint. Venous air embolism is an extremely rare complication of knee arthrography, but can occur. As it is potentially fatal, prompt recognition and appropriate positional and supportive therapy are essential.

Lumbar spine interbody fusion with reinforced hydroxyapatite implants.
Porous coralline and synthetic hydroxyapatite blocks reinforced with either self-reinforced polyactide or polyglycolide were implanted into 15 lumbar intervertebral disc spaces in five minipigs in order to determine whether they could provide an osteoconductive bridge for interbody fusion. Histological examination and radiological analysis with plain films, computed tomography and magnetic resonance imaging were carried out. The osteoconductive properties were promising; creeping bone formation could be observed, although no complete fusion had been achieved at 24 weeks.

Dynamic sonography in the diagnosis of ligament and meniscal injuries of the knee.
A total of 84 patients with ligament or meniscal injuries of the knee was prospectively examined clinically and under anaesthesia, by arthroscopy and sonography. The sensitivity, specificity, positive and negative predictive values were compared. For sonography a high resolution scanner (Picker LSC 7000 with a 5-MHz transducer) was used. ⋯ Repetitions are possible at will 7. Documentation is included 8. Sensitivity and specificity are very good.

Between 1970 and 1987, 94 patients received 208 silicone implants at the Department of Orthopaedics, University Hospital, Vienna. Of these, 62.5% were clinically followed up. ⋯ These changes were usually clinically inconspicuous and had little effect on patients' subjective well-being. Despite the low discomfort caused, however, the use of such implants in only recommended in critical and severe causes because of the progressive destruction of the osseous bed during the time the implant is in the body.

Short humerus: results of 11 prolongations in 10 children and adolescents.
The author evaluates the results of extension of 11 humeri in 10 children and adolescents with an average age of 12.5 years. The most frequent cause of the abbreviation was neonatal osteomyelitis. ⋯ The most serious complication was temporary paralysis of the nerves of the forearm and hand. Correction of the length of the upper extremities has a positive effect on the patient's psyche and on the aesthetic appearance and the functioning of the limb.
