Outcomes of basicervical femoral neck fracture treated with percutaneous compression plate (PCCP)

Abstract

Introduction: Basicervical femoral neck fracture is associated with high rates of failure due instability patterns, mainly collapse and rotational instability. The purpose of this study was to evaluate the clinical-radiological results of a group of patients with a bascervical proximal femoral fractures treated with Percutaneous Compression Plate (PCCP).

Material and methods: Among 5817 patients with a hip fracture who were admitted in our hospital from January 2005 to December 2017, 234 factures (4%) were diagnosed of basicervical femoral fracture. 30 of them were treated with a PCCP, 22 women and 8 men, mean age was 81.2 years (63-94). Demographic and perioperative variables were collected. The patients were followed up at 1, 3 and 6 months clinically and radiologically.

Results: There were no intra-operative complications and no conversions to open surgery. There was no early implant failure. No surgical wound infection was diagnosed. Crude mortality was 13% the first year and 87% were able to walk at the 6 months. The last follow-up x-rays revealed 97% fracture healing and the collapse at fracture site occurred in 4 hips. No instances of cut-out were observed. In one case, a fatigue failure of the lag screws of a PCCP plate was observed at 3 months from osteosynthesis.

Conclusion: PCCP is an appropriated implant for basicervical femoral neck fractures.
