Outcome of percutaneous compression plate for treatment of femoral neck fractures: mean follow-up of 4.4 years.

PURPOSE: Percutaneous compression plate (PCCP) provides superior anti-rotational abilities and mechanical strength in femoral neck fractures (FNFs). The first series reporting its utilization of FNFs was promising. Since the long-term outcome regarding the implant has not been reported, the purpose of this study was to evaluate the long-term functional outcomes and complications after fixation using PCCP in FNFs.

MATERIALS AND

METHODS

From 2010 to 2019, 51 patients aged from 18 to 87 years were evaluated; 11 patients were excluded from this study. Demographic data, fracture classification, and complications were analyzed. Besides plain radiographs and CT, uptake ratios using bone scintigraphy and/or SPECT were also collected and analyzed.

RESULTS

At a mean follow-up of 4.4 ± 2.0 years (range, 2-10 years), the mean Harris hip score was 88, with 44 patients (86.3%) achieving excellent or good outcomes. The rate of complication was 13.7% (7/51), with five cases of osteonecrosis of the femoral head (OFNH). Hip replacements were performed in four (7.8%) cases. After confirmation of normal transfusion status, 11 patients underwent elective removal of the implant without further complications.

CONCLUSION

Closed reduction and internal fixation using PCCP in FNFs resulted in satisfactory outcomes with low complication rates. Longer follow-up (3-5 years) and sequential bone scintigraphy or SPECT after surgery are recommended after internal fixation using PCCP.
