Application of Cannulated Compression Screws Combined with Medial Support Plate in Pauwells Ⅲ Type Femoral Neck Fractures and Its Impact on Lower Limb Function
Objective:To investigate the application of cannulated compression screws combined with medial support plate in treating Pauwells Ⅲ type femoral neck fractures and its impact on lower limb function.Methods:From April 2017 to August 2022,82 patients with Pauwells Ⅲ type femoral neck fractures admitted to our hospital were randomly allocated into an observation group and a control group(41 cases each).The control group received conventional cannulated compression screw fixation,while the observation group under-went additional medial support plate fixation.Perioperative indicators,Harris hip function scores,lower limb function,and short-and long-term postoperative complication rates were compared between the two groups.Results:The fracture healing time in the observation group was significantly shorter than in the control group,with longer surgical duration,more intraoperative blood loss,greater postoperative drainage volume,and extended hospital stay(P<0.05).No significant differences were observed in pain,function,and activity scores of the Harris hip function at postoperative day 3 between the two groups(P>0.05).However,at 3 months postoperatively,the pain score was lower and function and activity scores were higher in the observation group(P<0.05).No significant differences were found in stride length,cadence,or walking speed at post-operative day 3(P>0.05),but these parameters significantly improved at 3 and 6 months postoperatively,with better outcomes in the observation group(P<0.05).The complication rate was significantly lower in the observation group(4.87%)compared to the control group(26.83%,P<.05),and the incidence of chronic pain was also notably less in the observation group(4.87%vs.19.51%,P<.05).Conclusion:The combi-nation of cannulated compression screws and medial support plates is efficacious for Pauwells Ⅲ type femoral neck fractures,improving long-term hip joint function and lower limb function,reducing postoperative compli-cation rates,and alleviating postoperative chronic pain.This approach is worthy of clinical promotion.
