摘　　要：目的探讨导针钝头探通法辅助判断空心拉力螺钉置入深度在老年患者股骨颈骨折闭合复位内固定术中应用的效果。方法回顾性研究。纳入2016年10月—2020年10月河北医科大学第三医院创伤急救老年骨科收治的老年股骨颈骨折患者16例,其中男3例、女13例,年龄65~89(70.1±4.8)岁。患者均为GardenⅡ型骨折。均行闭合复位空心拉力螺钉内固定手术治疗,术中均使用导针钝头探通法辅助判断空心拉力螺钉置入深度。术后即刻复查患侧髋关节CT及三维重建,观察骨折断端对位、对线情况,螺钉的置入位置,测量螺钉尖与股骨头软骨下骨的距离,评估导针钝头探通法辅助判断螺钉深度技术的效果及有效性。术后1年内定期随访,观察切口愈合情况、骨折愈合时间以及内固定断裂、骨折不愈合等并发症的发生情况。术后6个月采用Harris评分评定疗效。结果16例患者均顺利完成手术治疗,手术时间为30~85(51.8±11.2)min,术中出血量为20~100(44.3±23.5)mL。16例患者共打入空心拉力螺钉49枚,术后即刻影像学检查显示,骨折断端对位、对线优良,螺钉的置入位置良好,螺钉钉尖与股骨头软骨下骨的距离为0.21~0.49(0.38±0.11)cm;螺钉置入位置均有效,有效性为优(100%)。术后患者伤口均一期愈合,未发生感染、内固定失败。16例患者均获随访,随访时间6~16(9.1±3.3)个月。随访期间无螺钉断钉、退钉及股骨头塌陷、坏死等并发症发生,骨折愈合时间为3~6(4.1±1.0)个月。术后6个月采用Harris评分评定疗效,16例患者疗效均为优良。结论在老年股骨颈骨折闭合复位内固定术中,使用导针钝头探通法辅助判断空心拉力螺钉置入深度,可将螺钉尖准确放置在股骨头软骨下骨下方0.5 cm范围内,有助于提高内固定稳定性、促进骨折断端良好愈合。Objective To determine the effect of the blunt head sounding of guide wire on the judgment of the depth of cannulated lag screw in the closed reduction and internal fixation of femoral neck fracture in the elderly.Methods A retrospective analysis was carried out on 16 elderly patients with femoral neck fracture admitted to the geriatric orthopedic trauma center of the Third Hospital of Hebei Medical University from October 2016 to October 2020.There were three males and 13 females in the age range of 65-89(70.1±4.8)years old.The fractures were Garden typeⅡ.The patients underwent closed reduction and internal fixation with cannulated lag screw.During the operation,the blunt end sounding of the guide wire was used to assist in judging the depth of the cannulated lag screw.CT and 3D reconstruction of hip joint on the affected side were reviewed immediately after the operation to observe the position and alignment of the broken end of the fracture and the the insertion position of screw.The distance between the cannulated lag screw tip and the subchondral bone of the femoral head was measured.The effect and effectiveness of using the blunt end sounding of the guide wire to assist in judging the depth of the screw were determined.Regular follow-up was conducted within 1 year after the operation to observe the wound healing,fracture healing time,breakage of internal fixation,and nonunion.The curative effect was evaluated by Harris score 6 months after the operation.Results Sixteen patients successfully underwent the operation.The operation time was 30-85(51.8±11.2)min,and the amount of intraoperative bleeding was 20-100(44.3±23.5)mL.A total of 49 cannulated lag screws were inserted into 16 patients.The CT and 3D reconstruction images of the hip joint on the affected side that were taken immediately after operation showed that the position and alignment of the broken end of the fracture were excellent,the insertion position of screw was good,the distance between the screw tip and the subchondral bone of the femoral
