Eight year results of Charnley arthroplasties of the hip with special reference to the behavior of cement.

Five hundred and forty-seven total hip replacements by the Charnley technique during 1967 and 1968 have been studied for the quality of the late results. The average follow-up was 8.3 years. Mechanical failure at the cement-bone interface occurred in only 2.2% of cases. A search was specially directed towards evidence of incipient pathology at the bone-cement interface in the absence of any suspicion of clinical defect. This was found in 12% of cases but it is emphasized that the criteria were exceptionally rigorous and entirely radiological. Because the cement technology used at that time is now considered unsophisticated, mechanical failure of cement is a preventable condition. A previous report of socket migration in 9.5% of cases is not confirmed by the present survey of a more recent series of cases.

Socket wear in Charnley low friction arthroplasty of the hip.

Five hundred forty-seven Charnley hip arthroplasties were measured for wear radiographically after an average period of 8.3 years. The operations were performed in 1967 and 1968 and the average rate of wear was 0.07 mm per year. This is only half that recorded for the operations in 1963, 1964, and 1965. Clinical radiographic methods of measuring socket wear are valid provided that the socket is inserted with the wear marker not more than 10 degrees from the coronal plane. This can be estimated provided that radiopaque cement is used.

Allergy to bee and wasp venom.

Insects make up 80% of the animal kingdom with over 800,000 species worldwide. Allergic reactions to bee or wasp stings are common and they may rarely be fatal. Patients who experience systemic sting reactions must receive effective treatment and assessment.
