PFNA combined reconstruction and locking titanium plate for the treatment of comminuted femoral intertrochanteric fractures involving lateral wall / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the operative effect of PFNA combined with reconstructive locking plate on the treatment of comminuted femoral intertrochanteric fracture which involving the lateral wall.</p><p><b>METHODS</b>A total of 35 patients with comminuted femoral intertrochanteric fractures involving the lateral wall were surgically treated from November 2014 to January 2016. According to whether there was reconstruction of the lateral wall or not and the internal fixation method, the patients were divided into PFNA group (no reconstruction of the lateral wall), PFNA recontruction group (reconstructive locking plate was used to reconstruct the lateral wall, PFNA internal fixation). The clinical curative effect was evaluated by the analysis of operation time, intraoperative blood loss, postoperative activity time, the time of fracture healing, complications, and hip joint Harris score at 12 months after operation.</p><p><b>RESULTS</b>All 35 patients completed the operation successfully. All the incisions were healed by first intention and no incision infection or fat liquefaction occurred. All 35 patients were followed up from 12 to 16 months with an average of 14.4 months. All patients had bone healing. There was no statistical significant in surgery time and intraoperative blood loss between two groups(>0.05). There were 5 postoperative complications in the PFNA group and 1 in the PFNA combined with reconstructive locking plate group. There was a statistical difference between two groups(<0.05). The postoperative activity time, bone healing time, complications, and Harris score of PFNA reconstruction group were all superior to PFNA group, there were statistically significant differences between two groups.</p><p><b>CONCLUSIONS</b>Although the operation time and blood loss of PFNA combined with reconstructive locking plate in treatment of comminuted femoral intertrochanteric fracture which involving the lateral wall are more than those in the PFNA group, and the surgical trauma is larger than PFNA, the fracture healing time, postoperative activity time, and hip joint function were all superior to those of the PFNA group, which can effectively shorten the postoperative bed rest time, and reduce bed complications as well as improve hip joint function.</p>
