Radiographic loosening after revision with gentamicin-containing cement for deep infection in total hip arthroplasties.

Seventy-two infected total hip arthroplasties were revised with cement containing gentamicin and were followed up with regular radiograms for periods of up to six years. The infection healed in 61 cases and persisted in 11. An analysis of the radiographic changes in regard to the signs of loosening showed that about half of the cases with a healed infection had a minimal demarcation between bone and cement.

Recurrences after initial dislocation of the shoulder. Results of a prospective study of treatment.

During the years 1978 and 1979, the results in 257 patients with a primary anterior dislocation of the shoulder were prospectively studied. The patients were less than forty years old and had been treated at twenty-seven Swedish hospitals. Thirty-two patients had a fracture of the greater tuberosity, but none of them reported having any further dislocations within two years after treatment, while 32 per cent of the patients without this fracture had a redislocation during the same period.

Posterior versus lateral approach for hip arthroplasty.

In a study of two groups of 100 patients each, with a similar composition (age, sex and indications for surgery), operations for total hip arthroplasty took half as long and the blood loss was clearly less when using the posterior route in one group compared with Charnley's conventional approach in the other group. These are important considerations for elderly patients with a high operative risk. Radiologic assessments showed that with the posterior approach there was a wider variation in the location of the cup in the frontal plane.
