Abstract
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.
