Two-year follow-up of femoral neck fractures. Comparison of osteosynthesis methods.
For 14 consecutive months, all 152 femoral neck fracture patients greater than or equal to 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 greater than 0.05) and in displaced fractures in 12/36 pinned and 23/32 nailed (p less than 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.
