failure in 6.4% of ?he patients during rhe perioperative period. During follow-up study (607 k 363 days), 7.3% required major amputation, ipsilateral to reconstruc!.ion, 5.5% required surgical or angiographic revision 50%) EF had greater overall survival by life table analysis than those with EF ~50% (p = 0.0006, Mantel-Cox test). Ventricular wall motion abnormalities were associated with re:luced overall survival (p = 0.008. Mantel-Cox test). The presence of angina or previous MI, singularly or in combination, did not have an adverse effect on overall survival, whereas diabetes (p = 0.0058, Manlel-Cox test] and cigarette smoking (p = 0.0137, Breslow test] were associated with significantly dimin!.shed overall survival. Preoperative RNVG can identify subgroups at a survival disadvantage after revascularization of the extremity in a population in which the presence of angina or previous MI does not predict survival.

NUCLEAR IMAGING AND X-RAY RESULTS AFTER CEMENTLESS HIP ARTHROPLASTY BY PM SHAFT SYSTEM (In German)

Kiihne J-H, Wirth CJ, Refior HJ, et al. (Orthopadische Klinik der Ludwig-MaximilliansUniversitat Munchen, Klinikum Grosshadern, Marchionistrasse 15, D-8000 Munchen 70. Germany). RoFo 1990;153:442-450. One-hu.ndred-forty-seven bone scans with ggmTc14DP following 60 cementless hip arthroplasties were analysed at 3 to 160 weeks after operation. Results are compared to clinical evaluation according to Merle

d’Aubigne. X-ray changes m ir numSar of patients are inciuded. In uncomplicated cases, bone-scan activity decreased quickly within 26 weeks postoperatively. Decrease of scintigraphic activity was markedly delayed in patients with low Merle d’Aubigne values or persisting pain. In four cases, bone-scan activity increased again. In these cases, reoperation revealed rotational instability of the shaft endoprostheses. Unusual x-ray phenomena such as development of a bony cup at the tip of the prosthesis or seams were found mainly in patients with less satisfying results. We consider nuclear imaging an important additional examination to evaluate bony integration of PM shaft endoprostheses after hip replacement, especially as interpretation of x-ray features alone is stiil doubtful.

SONOGRAPHY FOR SKELETAL METASTASES-A COMPARISON CONVENTIONAL RADIOGRAPHY

WITH CT AND (In German)

Just M, Rosier HP, Kutzner J, Thelen M (Institut fur klinische Strahlenkunde, Universitat Mainz, Langenbeckstr. 1, D-6500 Mainz, Germany:. RGFo ?990;153:451-455. The value of computed tomography (CT], conventional radiography, and ultrasound (US) was compared in 40 patients with 52 skeletal metastases. For superficial lesions, the combination of sonography and conventional radiography was equivalent to CT in showing the extent of bone destruction and soft:issue involvement. As expected, sonography was unsatisfactory for deeper lesions. US can provide useIul information for planning radiation therapy for superficial lesions, but it does not replace conven:ional radiography. Authors’ Summary
