Background: Early diagnosis of avascular necrosis of femoral head is crucial to
prevent morbidity associated with its eventual outcome. The aim of this study is to
find out whether intra-operative marrow aspiration volume from the supero-lateral
part of femur head can be considered as an early diagnostic sign of avascularity of
femur head after hip dislocation. Methods: In a one year prospective study, 22 cases
of hip dislocation/fracture dislocation that had presented unreduced at more than 12
hours post injury were included. Intraosseous aspiration, marrow fluid analysis and
core biopsy histological analysis was performed from the supero-lateral (test group)
and central part (control group) of femur head. After appropriate surgical treatment
and postoperative management, these patients were followed up till the end of 2
years by clinical, radiological and magnetic resonance imaging evaluation of the
affected hip. Results: Eventually 8 patients developed avascular necrosis (AVN) of
femoral head. The analysis of test group samples revealed, 9 patients had aspirate
volume of 1cc and showed
viable cells on histology. Conclusion: Intra-operative assessment of marrow-aspirate
volume (
