classification,there were 6 patients with type Ⅰ,39 with type Ⅱ,20 with type Ⅲ,and 9 with type Ⅳ fractures.Results Duration from injury to operation was (5.7 ± 2.2) days.Operation time lasted for (73.4 ± 31.5) minutes and intraoperative blood loss was (116.4 ± 99.2) ml.Seventy patients were operated on without blood transfusion.Sixty-six patients were followed up for (18.9 ± 8.4) months.Harris score was (92.9 ±5.0) points at final follow-up,with the excellent-good rate of 99％.Sixty-five patients could walk independently,but one walked with the help of crutches.Partial weight-bearing time was (3.6 ± 1.7) days and full weight-bearing time was (2.1 ± 1.4) months.All fractures healed in a period of (3.9 ± 1.6) months.Two patients had delayed union; two developed avascular necrosis including 1 with displaced fracture and 1 undisplaced fracture.Conclusions Internal fixation with PCCP has advantages of decreased trauma,rigid fixation,early weight bearing,good function outcome,and low risk of complications.
