  • Title: 85Sr-scintimetry in femoral neck fracture.
    Author: Brümmer R, Hansson LI, Mortensson W, Sjöstrand LO.
    Journal: Arch Orthop Trauma Surg (1978); 1982; 101(1):47-51. PubMed ID: 7165500.
    Abstract:
    In 40 patients with fracture of the femoral neck 85Sr scintimetry was performed at the time of nailing and 4 months postoperatively. The fractures were radiographed repeatedly for 5 years; thirteen fractures healed without complications, 22 developed necrosis of the femoral head, and 5 pseudarthrosis. The early isotope measurement did not distinguish between normal and necrosis cases even with detailed analysis. The 4 months activities were high in osteonecrosis and low pseudarthrosis. The latter observation is interpreted as evidence that non-union of a femoral neck fracture is due to severe permanent vascular damage.
