Two-year follow-up of femoral neck fractures: Comparison of osteosynthesis methods

Abstract

For 14 consecutive months, all 152 femoral neck fracture patients ≤50 years of age admitted to the Lund University Hospital were operated on with two hook-pins if born on an uneven date and a four-flanged nail if born on an even date. A clinical 2-year follow-up revealed a 35 per cent mortality. Among survivors, radiographic healing complications were seen in undisplaced fractures in 1/13 pinned and 5/14 nailed (p>0.05) and in displaced fractures in 12/36 pinned and 23/32 nailed (p < 0.01). This outcome correlated well with the early postoperative scintimetry. Reoperation within 2 years had been performed for seven pinned and 19 nailed fractures. In hook-pinning, thus, less than one patient out of 12 needed a reoperation with THR within 2 years. This figure is interpreted as strongly favouring hook-pinning before arthroplasty as the primary procedure in femoral neck fracture. © 1984 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.
