Clinical efficacy of a new femoral locking plate combined with titanium cables internal fixation in treatment of Vancouver B1 periprosthetic femoral fractures
Objective To evaluate the clinical efficacy of a new femoral locking plate in combination with titanium cables for the treatment of Vancouver type Bl periprosthetic femoral fractures.Methods Clinical data of 10 patients with Vancouver type Bl periprosthetic femoral fractures treated with a new femoral locking plate in combination with titanium cables bundling from June 2019 to June 2022 were retrospectively analyzed.After fracture reduction,the locking plate was placed lateral to the femur,the proximal hook was attached to the greater trochanter.On the proximal side of the femur,1 titanium cable was passed through the channel,the femur was fixed to the plate by tensioning the titanium cable.Flat-head locking screws were used for proximal unicortical fixation,distal bicortical fixation was achieved by placing locking screws percutaneously through a small minimally invasive incision.Results All patients successfully completed the surgery with a follow-up of 12～27 months,there were no complications such as incision infection,internal fixation and prosthesis loosening or fracture.One patient had preopera-tive deep vein thrombosis,vein filters were placed by vascular surgery and the procedure was completed.Operative time in this group ranged from 110 to 160 minutes,intraoperative bleeding ranged from 100 to 500 mL with a mean of 370.0 mL.Intraopera-tive blood transfusion was performed in eight patients,seven of whom received 2 U erythrocyte suspension and 200 mL plasma,and one received 4 U erythrocyte suspension and 200 mL plasma.Four patients received postoperative blood transfusions for ane-mia,three with 2 U erythrocyte suspension and 200 mL plasma,and one with 2 U erythrocyte suspension.The hospital stay of our patients ranged from 12 to 20 days,and fracture healing time was 4 to 6 months with a mean of 4.8 months.At the final follow-up,patients had a Harris hip function score ranging from 72 to 92,the mean score was 82.2.Conclusion The new femoral lock-ing plate combined with titanium cables bundling for the treatment of Vancouver type B1 periprosthetic femoral fractures can achieve strong fracture fixation and accelerate early patient recovery.The recent clinical results are better.
