目的:比较髓内钉与锁定钢板治疗老年肱骨近端Neer二、三部分骨折的疗效。方法:回顾性分析2018年1月至2021年6月康复大学青岛医院(青岛市市立医院)骨关节与运动医学科行手术治疗的61例肱骨近端Neer二、三部分骨折老年患者临床资料。根据内固定方式不同分为2组:髓内钉组29例(采用肱骨髓内钉系统固定)与锁定钢板组(采用肱骨近端锁定钢板系统固定) 32例。分析比较两组围手术期、随访及影像学资料。结果:髓内钉组和锁定钢板组患者术前一般资料比较差异均无统计学意义(P > 0.05),具有可比性。髓内钉组手术时间、切口长度、术中出血量均显著优于锁定钢板组(P 0.05)。髓内钉组不良反应发生率(6.90%, 2/29)显著低于锁定钢板组(28.13%, 9/32),差异有统计学意义(P Objective: To compare the clinical effects of the intramedullary nail and locking plate in the treat-ment of Neer two- and three-part fractures of the proximal humerus in the elderly. Methods: A ret-rospective study was performed on 61 elderly patients with Neer two- and three-part fractures of the proximal humerus who had been operatively treated at the Department of Orthopedic Surgery and Sports Medicine, Affiliated Hospital of the University of Health and Rehabilitation Sciences (Qingdao Municipal Hospital) from January 2018 to June 2021. Of them, 29 were fixated by humeral interlocking intramedullary nails and 32 by proximal humeral locking compression plates. The documents concerning the perioperative period, follow-up, and radiographs were analyzed and compared between the two groups. Results: The differences between the general preoperative data of patients in the intramedullary nail and locking plate groups were not statistically significant (P > 0.05) and were comparable. The operating time, incision length, and intraoperative bleeding were significantly better in the intramedullary nail group than in the locking plate group (P 0.05). The incidence of advers
目的:探讨基于CT相关数据测量的术前规划在全髋关节置换术中的临床应用。方法:收集2022年10月至2023年3月76例初次行单侧非骨水泥全髋关节置换患者进行回顾性分析,将其分为两组,研究组39例通过术前螺旋CT三维重建技术测量髋臼横径,髋臼前倾角、外展角,两侧髋关节旋转中心垂直差值,两侧偏心距差值,双下肢长度差值,股骨颈截面髓腔长径及股骨干峡部的最小髓腔内径数值行术前规划预测假体型号及其位置,对照组37例不进行CT术前规划。比较两组患者术后CT相关参数,手术相关指标(手术时间、术中出血量、术后引流量),术后1年髋关节Harris评分、VAS评分有无差异。结果:两组术前临床指标及一般资料不存在统计学差异(P > 0.05);两组术后双下肢长度差值、两侧旋转中心差值、两侧偏心距差值均小于术前,且研究组小于对照组(P 0.05)。结论:基于CT相关数据测量的术前规划对全髋关节置换术具有极大指导意义。Objective: To investigate the clinical application of preoperative planning based on CT-related data measurements in total hip arthroplasty (THA). Methods: A retrospective analysis was conducted on 76 patients who underwent unilateral non-cemented THA for the first time between October 2022 and March 2023. The patients were divided into two groups: the study group (n = 39) underwent preoperative planning, including measurements of acetabular transverse diameter, acetabular anteversion angle, abduction angle, vertical difference in rotational centers of both hips, difference in offset between hips, difference in bilateral limb lengths, femoral neck cross-section medullary canal length, and minimum medullary canal diameter at the femoral isthmus through spiral CT three-dimensional reconstruction technology to predict the prosthesis size and position;the control group (n = 37) did not undergo CT-based preoperative planning. The postoperative CT-related parameters, surgical ind
