Summary

  1. 1.

    The preoperative administration of tetracycline and the evaluation of bone biopsies by fluorescence microscopy is a simple and reliable way of assessing the preoperative blood circulation to the femoral head after a femoral neck fracture.

  2. 2.

    Nine patients out of 52 showed no tetracycline deposition. These 9 belonged to the group of 39 displaced fractures. All of the 13 with a minimum or no displacement showed signs of tetracycline deposition.

  3. 3.

    The risk of a vascular injury after a femoral neck fracture was greater in younger patients.

  4. 4.

    Deficient tetracycline deposition was connected with defective isotope uptake in the femoral head when TcMDP scintimetry was performed within the first two weeks after operation. Presence of tetracycline deposition in the biopsy specimens could be combined with decreased, normal, or increased isotope uptake in the femoral head during the postoperative investigation.

  5. 5.

    The incidence of a total preoperative vascular deficiency as measured by tetracycline biopsies, is considerably lower than the frequency of a postoperative avascular necrosis of the femoral head. The probable explanation is that also partial avascularity of the femoral head predisposes to avascular necrosis or that further damage to the femoral head vessels occurs during operation, or postoperatively.

  6. 6.

    Further studies are being carried out to evaluate the effects of closed reduction and nailing. The patients in this material will be followed up for radiographical signs of avascular necrosis.

Zusammenfassung

  1. 1.

    Tetracycline preoperativ zu verabreichen und eine Knochen-Biopsie mit dem Fluorescence-Mikroskop zu analysieren, ist eine einfache und zuverlässige Weise, den preoperativen Blutkreislauf zum Oberschenkelkopf hin nach einer Oberschenkelhalsfraktur festzustellen.

  2. 2.

    Nur 9 von 52 Patienten zeigten keine Tetracycline-Einlagerung; 9 von 39 Frakturen mit Fehlstellung, aber keine von 13 Frakturen ohne Fehlstellung.

  3. 3.

    Das Risiko für Gefäßschäden preoperativ nach einer Oberschenkelhalsfraktur erwies sich bei jüngeren Patienten als größer.

  4. 4.

    Der Mangel von Tetracycline war mit defekter Isotopaufnahme im Oberschenkelkopf verbunden, wenn TcMDP Scintimetrie während der zwei ersten Wochen nach der Operation durchgeführt wurde. Das Vorhandensein einer Tetracycline-Einlagerung in den Knochen-Biopsien konnte mit einer verringerten, normalen oder vergrößerten Isotopaufnahme im Oberschenkelkopf bei der postoperativen Untersuchung nachgewiesen werden.

  5. 5.

    Die Inzidenz eines totalen Schadens der Blutzufuhr preoperativ, durch die Tetracycline-Biopsie beurteilt, ist erheblich geringer als die Frequenz einer postoperativen avaskularen Nekrose des Oberschenkelkopfes. Die wahrscheinliche Erklärung ist die, daß auch eine partiell abgebrochene Blutzufuhr zum Oberschenkelkopf für avaskulare Nekrose prädisponiert oder daß ein weiterer Schaden der Blutgefäße zum Oberschenkelkopf während oder nach der Operation hervorgerufen wird.

  6. 6.

    Damit man den Effekt einer geschlossenen Reposition und Nageln bewerten kann, werden z. Z. weitere Studien betrieben. Die Patienten dieser Fälle werden bezüglich röntgenologischer Merkmale einer avaskularen Nekrose weiter beobachtet.
