| Objective： To compare the outcomes between Percutaneous compression plate(PCCP) and three cannulated screws in the treatment of displaced femoral neck fractures inyoung patients.Methods： Between October2010and November2012,40eligible patients withdisplaced femoral neck fractures were included in this retrospectively study and treated byclosed reduction and internal fixation using either the PCCP implant (21patients) or threecannulated screws (19patients). There were no significant differences between the2groups with respect to the general information (P>0.05). The patients were followed-upmonthly until six months after operation, then every three months clinically andradiographically to evaluate their rates of union and complications.Results： The average follow-up was23.7months (range, from12to37months) forthe40patients. There were no significant differences in the duration of follow-up,reduction quality, operation time, intraoperative blood loss, total perioperative blood loss,postoperative and total hospital stay, time of fracture union and the Harris hip score at thelast follow-up between the two groups (P>0.05). The partly and full weight-bearing time,the Harris hip score at3months after operation, and pain level at the last follow-up of thePCCP group were significant better than three cannulated screws group (P<0.05). In threecannulated screws group, there were5avascular necrosis,4back-out and1varus deformity.There was just1avascular necrosis occurred in PCCP group. There was significantdifference in the total incidence rate of complications between the two groups:8patientswith three cannulated screws and1with PCCP (P<0.05).Conclusions： PCCP had the advantages of less trauma and simple to operative aswell as three cannulated screws. In contrast to three cannulated screws, the PCCP was more stable, allowing earlier weight-bearing, and with better functional results forshort-term outcomes, and lower total incident rate of complications. |
