    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.

    Notes: Summary In a prospective and consecutive study we evaluated the prevalence of pain-related symptoms, the results of the strainght leg raising (SLR) test and neurological disturbances by age group in a total of 150 patients operated on due to lumbar disc herniation. On admission, all patients were interviewed, and pain at rest, at night and on coughing was recorded. Walking capacity was recorded under four categories:1–5 km, 0.5〈1 km and〈0.5 km. Results of the SLR test were also registered as category data: positive 0–30°, positive 30–60°, positive 〉60° or negative. Findings from examination of tendon reflexes and power of the extensor hallucis longus (EHL) muscle were registered, as were sensory disturbances. The above mentioned parameters were analysed separtely for five different age groups: 20–29 years, 30–39 years, 40–49 years, 50–59 years and above 60 years of age. There was an age-related change in the prevalence of certain parameters. Highly restricted positive SLR test results and pain on coughing was most commonly found in the youngest patient group. With increasing age there was a decreasing prevalence of highly restricted positive SLR test results, while the prevalence of severe reduction of walking capacity increased. In short, the youngest patient group showed the most obvious clinical picture of disc herniation and, with increasing age, the clinical picture gradually changed towards the picture associated with spinal stenosis.

    Notes: Summary For metastatic disease of the spine, anterior operations on the vertebral bodies often include methylmethacrylate cementation. The cement curing process may produce high temperatures in the surroundings, as demonstrated in joint replacement surgery, and there is a risk of thermal injury to the spinal nerves. In cadavers, we studied the heat arising during curing of cement on the dural sac, and the temperature of the cement surface was measured when the vertebral body was reconstructed using acrylic cement in the same way as in tumor surgery. The temperature increase on the surface of the dural sac during polymerization was between 4° and 12°C, depending on the amount of protection. Only a moderate temperature elevation was measured on the surface of the dural sac, provided that the posterior cortex of the vertebra was retained together with 0.5 cm of the spongious bone or a silicone membrane.

    Description / Table of Contents: Résumé Deux groupes comparables de fractures du col du fémur, de 28 patients chacun, traités l'un par ostéosynthèse, l'autre par arthroplastie secondaire à une complication du traitement primitif, ont été évalués et comparés cinq ans ou plus après la première intervention d'ostéosynthèse. Le questionnaire du «Nottingham Health Profile» a été envoyé et retourné par courrier, et les groupes de malades ont été appariés en fonction de l'âge, du sexe, de l'état de santé et de la situation sociale. Les patients ayant une fracture consolidée ont moins de problèmes de sommeil, d'activité ménagère et de loisirs que ceux qui ont eu besoin d'une arthroplastie totale secondaire.
    Notes: Summary Two matched groups of 28 patients each, with femoral neck fractures treated by primary internal fixation or by secondary total hip replacement after a complication of primary treatment, were evaluated and compared five years or more after primary pin fixation or secondary total hip replacement. The Nottingham Health Profile questionnaire was sent and returned by mail and the patient groups were matched with regard to age, sex, health, and social situation. Patients with healed fractures had less problems with sleep, housework and hobbies, and thus functioned better than patients who had required a secondary total hip replacement.

    Notes: Abstract The aim of this study was to determine MRI findings in patients successfully operated upon for lumbar disc herniation. We investigated 20 patients with a successful outcome after L4-5 or L5-S1 disc operations clinically and with MRI preoperatively, and at 5 days, 6 weeks, and 4 months after surgery. Postoperatively, T1- and T2-weighted images were obtained. At 4 months gadolinium-enhanced images were added. Pronounced intraspinal MRI changes were seen during follow-up. Deformation of the dural sac was seen in 13 patients preoperatively, in 19 at 5 days after operation, in 15 at 6 weeks, and in 12 at 4 months. Nerve root involvement was seen in all cases both preoperatively and at 5 days after operation, in 17 at 6 weeks, and in 15 at 4 months. No correlation between symptoms or the straight leg raising test and the size or nature of the abnormal tissue in the spinal canal postoperatively could be demonstrated. It was concluded that early postoperative MRI after lumbar discectomy must be interpreted carefully, and that oedema and scar formation are probable reasons for difficulties in interpretation.

    Description / Table of Contents: Zusammenfassung Osteonekrose mit einem akuten Kollaps des Oberschenkelkopfes trat bei einer 79jährigen Frau auf, die vor 28 Jahren eine Oberschenkelhalsfraktur erlitten hatte. Das Auftreten röntgenologischer Veränderungen und klinischer Symptome beruhte auf neuen funktionellen Anforderungen an die Hüfte nach einer neuerlich erlittenen contralateralen, pertrochanteren Fraktur. Der Kollaps des Oberschenkelkopfes machte eine Hüftgelenktotalendoprothese erforderlich. Eine Bestimmung der Oberschenkelkopfvitalität zum Zeitpunkt der Arthroplastik zeigte eine partielle Durchblutungsstörung des Kopfes als Voraussetzung für den Kollaps. Mit großer Wahrscheinlichkeit beruht die Durchblutungsstörung auf der vor 28 Jahren erlittenen Oberschenkelhalsfraktur.
    Notes: Summary Osteonecrosis and acute collapse of the femoral head occurred in a 79-year-old woman with a history of femoral neck fracture sustained 28 years previously. The occurrence of radiographic signs and clinical symptoms was associated with new functional demands on the hip because of a recent contralateral hip fracture. The femoral head collapse necessitated total hip arthroplasty. Determination of femoral head vitality at the time of arthroplasty implicated partial avascularity of the head as a cause of the collapse. With high probability, this partial avascularity was induced by the femoral neck fracture sustained 28 years earlier.

    Description / Table of Contents: Zusammenfassung Bei einem 22jährigen Mann wurde wegen rezidivierender vorderer Luxation der rechten Schulter eine Verlagerung des Processus coracoideus nach Bristow-Latarjet vorgenommen. Neun Monate später zog sich der Patient bei einem mäßigen Trauma eine erneute Luxation dieses Schultergelenkes zu. Im Röntgenbild war eine Verbiegung der Schraube erkennbar. Es wurde eine Subscapularisverkürzung nach Putti-Platt ausgeführt. Danach trat keine weitere Luxation mehr auf, und auch eine Instabilität des Schultergelenkes konnte nicht festgestellt werden. Ein Jahr später erwachte der Patient am Morgen mit Schmerzen an der Rückseite des rechten Schultergelenkes. Das Röntgenbild zeigte jetzt einen Bruch der Schraube; ihr proximaler Teil befand sich unterhalb des Humeroscapulargelenkes. Dieser Teil der Schraube wurde operativ entfernt. Danach war der Patient beschwerdefrei und konnte seiner Tätigkeit als Schreiner wieder voll nachgehen.
    Notes: Summary A 22-year-old male was operated on with coracoid transfer according to the Bristow-Latarjet procedure because of recurrent anterior dislocation of his right shoulder. Nine months later the patient sustained a repeat shoulder dislocation after moderate trauma. The screw was radiographically found to be bent. Subscapularis shortening according to Putti-Platt was performed. No repeated episodes of dislocation and no instability has been experienced by the patient since then. However, one year later, he awoke with pain dorsal to the humeroscapular joint. Radiographs showed the screw to be broken. The proximal part of the screw was located underneath the humeroscapular joint and was removed. After this, the patient was free of pain and returned to work as a carpenter.

    Description / Table of Contents: Zusammenfassung Mit Tetracyklinmarkierung und 99mTc-MDP-Scintimetrie wurden die sukzessiven Veränderungen der Vitalität des Oberschenkelkopfes nach einem Oberschenkelhalsbruch bei 7 Patienten, die eine Redislokation, eine Pseudarthrose oder einen segmentären Kollaps entwickelt hatten, untersucht. Bei den Reoperationen (Hüftarthroplastiken) wurden die Oberschenkelköpfe entfernt, in Scheiben zersägt und analysiert. Vor der Osteosynthese (Tetracyklinmarkierung) war die Vitalität in einem Fall nicht nachweisbar und eine Pseudarthrose die Folge, während in den übrigen Fällen eine moderate Reduktion beobachtet wurde, die in den apikalen Teilen am stärksten war. Die Scintimetrie 1–2 Wochen nach der Osteosynthese zeigte in sämtlichen Fällen eine verminderte Aufnahme. Die Scintimetrie einige Stunden vor der Reoperation zeigte in sämtlichen Fällen eine erhöhte Aufnahme. Die Isotopanalyse der extrahierten und zersägten Oberschenkelköpfe zeigte apikal eine markante Reduktion, in den anterioren und distalen Teilen eine moderate Reduktion und eine zufriedenstellende Aufnahme posterior und um die Fovea, wenn auch mit individuellen Variationen. Es wurde festgestellt, daß die Aufnahmeerhöhung (Revaskularisation), die postoperativ bei den avaskularen Oberschenkelköpfen gesehen wird, eine Realität ist, und daß bei Oberschenkelhalsbrüchen dem apikalen Teil des Oberschenkelkopfes der größte Gefässchaden zugefügt wird. Dieser Teil wird anscheinend auch am langsamsten revaskularisiert.
    Notes: Summary In seven patients suffering redisplacement, nonunion or segmental collapse after nailing of femoral neck fractures, subsequent changes in the vitality of the femoral head were studied with tetracycline labeling and 99mmTc-MDP scintimetry. At reoperation (total hip arthroplasty), the femoral heads were extracted and sawn into slices which were then analyzed. Vitality before nailing was totally lacking (tetracycline labeling) in one case (nonunion), and in the remaining cases moderate reduction was seen, most pronounced in the apical part of the head. In all cases, scintimetry 1–2 weeks after nailing showed reduced femoral head uptake of 99mTc-MDP, but scintimetry some hours before reoperation showed increased femoral head uptake. Isotope analysis of the slices from the extracted femoral heads showed marked reduction of uptake in the apical part of the head, moderate reduction in the distal and anterior parts, and satisfactory uptake in the posterior part of the head and the foveal region, though with individual variations. It was concluded that there is a genuine increase in uptake (revascularization) later in the course in postoperatively avascular heads, and that the apical part of the femoral head sustains the most pronounced vascular damage in femoral neck fracture and is probably the slowest to revascularize.
