    Description / Table of Contents: Summary During the last decade a decrease in postoperative infections in femoral neck fracture osteosynthesis was noted which led us to review all femoral neck fractures for infection. In a retrospective series of 1894 femoral neck fractures, the majority of which were included in other limited prospective studies, a total of 15 deep infections were diagnosed (0.8%). Staph. aureus was the most common bacterium cultured, and the diagnosis was established more than 4 months postoperatively in 9 of the patients. A total of 658 of the 1894 patients, who had pre- or peroperative tetracycline administration for measuring bone turnover, had two deep infections (0.3%). Among the remaining 1236 patients without antibiotic prophylaxis, 13 deep infections were diagnosed (1.0%). This difference suggests considering antibiotic prophylaxis in femoral neck fracture osteosynthesis. Eight of the infections led to THR, usually two-stage ; no signs of recurrent infection ensued, and the hip function of these patients was restored. The remaining 7 patients had Girdlestone procedures, also without recurrent infection, but with inferior functional outcome.
    Notes: Résumé On a noté pendant les dix dernières années une chute du nombre d'infections postopératoires dans les ostéosynthèses des fractures du col fémoral, ce qui nous a amené à revoir tous les cas infectés de ces fractures. Lors d'une série rétrospective de 1 894 fractures du col fémoral, dont la plupart étaient dans d'autres études prospectives limitées, on a diagnostiqué un total de 15 infections profondes (0,8 %). Le staphylocoque doré était la bactérie la plus souvent en cause ; le diagnostic était établi plus de 4 mois après l'intervention chez 9 des patients. 658 patients sur les 1 894, auxquels il avait été administré des tétracyclines per-opératoires pour mesurer le renouvellement osseux, ont présenté deux infections profondes (0,3 %). Parmi les 1 236 patients restants, sans antibioprophylaxie, on a comptabilisé 13 infections profondes (1,0 %). Cette différence incite à recommander la prophylaxie antibiotique dans l'ostéosynthèse de la fracture du col du fémur. Huit des infections ont conduit à une arthroplastie totale de la hanche, habituellement en deux étapes ; il n'y eut pas de récidive d'infection, et la fonction de la hanche fut rétablie chez ces patients. Les 7 patients restants ayant subi une résection de type Girdlestone, n'eurent aucune récidive d'infection, mais leur résultat fonctionnel fut moins bon.

    Description / Table of Contents: Résumé Les auteurs ont étudié comment les différentes talonnettes, de plastique ou de caoutchouc, atténuent l'impact du talon au sol. Ils ont enregistré la réponse à cet impact au moyen d'accéléromètres fixés à la peau. Treize malades atteints de polyarthrite rhumatoïde et porteurs d'une prothèse du genou ont été testés, ainsi que cinq sujets sains. Les talonnettes internes de 6 mm d'épaisseur ne réduisent pas de façon significative la décélération tibiale produite par l'impact au sol. A l'inverse, les chaussures munies d'une talonnette de polyuréthane épaisse de 20 mm diminuent significativement l'amplitude de la réponse tibiale, comparativement aux talonnettes de caoutchouc. On discute les implications possibles de ces observations chez les malades présentant des affections articulaires dégénératives ou porteurs de prothèse articulaires.
    Notes: Summary The capacity of heel inserts of different plastic and rubber materials to attenuate heel-strike forces was analysed. The heel-strike response was recorded by accelerometers fastened on to the skin. Thirteen rheumatoid patients with a knee arthroplasty and five healthy controls were tested. Inlay material of 6 mm thickness did not significantly reduce the tibial deceleration produced by heel-strike. However, shoes with heels of polyurethane plastic of 20 mm thickness significantly lowered the amplitude of the tibial response compared with rubber-heeled shoes. The possible implications of this for patients with degenerative joint diseases or with joint implants is discussed.

    Notes: Abstract Objective: The pharmacokinetics of cloxacillin was investigated in 14 men and 24 women undergoing cemented hip (n = 19; age range 56–90) or knee replacement surgery (n = 19; age range 51–84) for osteoarthritis. Cloxacillin 1 g was given intravenously as a bolus dose at the induction of anesthesia, and plasma samples and urine were collected for 6 h. Drug levels were determined using HPLC. Results: Preoperative serum creatinine levels were 84 μmol · l−1 in hip patients and 72 μmol · l−1 in knee patients. The calculated values for creatinine clearance were 63 and 85 ml · min−1 · 1.73 m−2, respectively. Total clearance of cloxacillin was 134 ml · min−1 · 1.73 m−2 in eighteen evaluated patients undergoing hip replacement, and 162 ml · min−1 · 1.73 m−2 in eighteen patients undergoing knee surgery. Renal clearance was 72 and 79 ml · min−1 · 1.73 m−2, respectively. Non-renal clearance was 57 ml · min−1 · 1.73 m−2 in hip patients and 77 ml · min−1 · 1.73 m−2 in knee patients. Renal clearance of cloxacillin correlated with the estimated creatinine clearance (r = 0.652). Although women received higher doses than men (median 2.02 vs 2.32 mmol · 1.73 m−2), there were no sex differences in clearance corrected for body surface area. Conclusion: Total clearance of cloxacillin was lower in patients undergoing hip replacement than in patients undergoing replacement of the knee, but there was no difference between men and women.

    Notes: Summary Four hundred and thirty femoral trochanteric fractures operated with nail-plate (McLaughlin), Ender, or sliding screw-plate (Richard) osteosynthesis were followed up radiographically and clinically. For each method of osteosynthesis the initial nail position was correlated to the occurrence of late mechanical complications. Unstable fractures were associated with a higher incidence of one or more clinical complications such as repeated surgery, post-operative death, or increased pain. For Ender osteosynthesis correlations were found between several mechanical and clinical complications, while for Richard's osteosynthesis mechanical complications were significantly correlated to repeated surgery only. McLaughlin and Ender osteosyntheses had a higher incidence of reoperations than Richard's osteosynthesis, whereas the mobility and ADL function were the same at 4 months.

    Description / Table of Contents: Zusammenfassung Trauma disponiert zur bakteriellen Arthritis. Im vorliegenden Bericht wird eine posttraumatische bakterielle Arthritis mit Luxation des Ellbogengelenkes beschrieben. Um die Infektion unter Kontrolle zu bringen und die Luxation zu reponieren wurde zusätzlich zur systemischen Behandlung mit Antibiotika eine Synovektomie durchgeführt und das Ellbogengelenk durch externe Fixation ruhiggestellt.
    Notes: Summary Trauma predisposes an individual to bacterial arthritis. This report describes a case of posttraumatic bacterial arthritis with luxation of the elbow. It was necessary to perform synovectomy as a complement to systemic antibiotic treatment in order to control infection and reduce the dislocation. The use of external fixation is demonstrated.

    Description / Table of Contents: Zusammenfassung Die Häufigkeit und die Ursachen von Luxationen bei 71 Totalprothesen und 59 Hemiarthroplastiken des Hüftgelenkes nach fehlverheilten, genagelten Schenkelhalsfrakturen wurden untersucht. Luxationen waren häufig und traten bei vier (6%) bzw. sieben (12%) Hüften auf. Eine Fehlstellung der Implantate erhöhte das Luxationsrisiko. Eine Totalprothese mit guter Position zeigte eine bessere Stabilität als eine Hemiarthroplastik.
    Notes: Summary The frequency of and the factors causing dislocations of 71 total hip replacements and 59 hemiarthroplasties following failure of nailed femoral neck fractures were investigated. Dislocations were frequent and occurred in four (6%) and seven (12%) hips respectively. Malposition of the components increased the risk for dislocation. A well-positioned total hip replacement was more stable than a hemiarthroplasty.

    Description / Table of Contents: Zusammenfassung Vierzig Patienten wurden wegen nicht geheilter Schenkelhalsfrakturen durch totale Hüftarthroplastik operiert. Das Durchschnittsalter war 73 Jahre, Frühsterblichkeit kam nicht vor, zwei Hüften luxierten. Nach zwei Jahren lebten 38 Patienten noch and wurden wieder untersucht. Die Ergebnisse bezüglich Schmerzfreiheit, Gehvermögen und Funktion waren befriedigend. Die totale Hüftarthro-plastik ist als die rettende Operation der Wahl zu betrachten.
    Notes: Summary Forty patients were treated by means of total hip arthroplasty after nailing of femoral neck fractures had failed. Their average age was 73 years. Thirty-eight patients were still alive after 2 years and were reviewed. Two hips dislocated, but there was no early mortality. The results regarding pain, walking capacity, and function were good, and total hip replacement is considered to be the salvage operation of choice.
