■髋关节置换术后的腿部长度差异会导致患者不满;因此,术前规划和植入物选择至关重要.这项研究的目的是测量我们人群的关节-转子距离(ATD)和股骨颈长度(FNL),并将其与3种最常用的非骨水泥茎进行比较。
■在这项横断面研究中,在2022年1月至7月之间收集了401名健康成年人的髋部X光片。测量垂直ATD和FNL。使用线性回归模型来确定这些测量值与年龄之间的关系,性别,和高度。使用逻辑回归模型来评估天然臀部与茎的颈部长度的匹配。
■平均年龄为60岁,74.56%为女性。在94.3%的臀部,ATD是阴性的,3.73%中性,2%为阳性。在我们的人口中,0.25%的民解力量比POLARSTEM短(史密斯和侄子,英国),比MetaFix茎短10.72%(Corin,英国),比绳索茎短11.97%(DePuySynthes,美国)。在逻辑回归分析中,POLARSTEM的匹配与年龄相关,但与性别或身高无关.相反,对于MetaFix和Corail,茎匹配与性别和身高有关。
■人体测量的髋部测量因人而异,和变量,如年龄,性别,术前计划和植入物选择时必须考虑高度,以避免腿长度差异。其他研究,包括不同的植入物,需要指导外科医生选择与患者天然髋关节最匹配的股骨柄。
UNASSIGNED: Leg length discrepancy following hip arthroplasty causes dissatisfaction to the patient; thus, preoperative planning and implant selection is critical. The purpose of this study was to measure the articular-trochanteric distance (ATD) and femoral neck length (FNL) in our population and compare them to those of 3 of the most used uncemented stems.
UNASSIGNED: In this cross-sectional study, 401 hip radiographs of healthy adults were collected between January and July 2022. The vertical ATD and FNL were measured. A linear regression model was used to identify the relationship between these measurements and age, sex, and height. A logistic regression model was used to assess the matching of native hips with the neck length of the stem.
UNASSIGNED: Mean age was 60 years, and 74.56% were women. In 94.3% of hips, the ATD was negative, 3.73% neutral, and 2% positive. In our population, 0.25% of FNL were shorter than POLARSTEM (Smith & Nephew, UK), 10.72% shorter than MetaFix stem (Corin, UK), and 11.97% shorter than Corail stem (DePuy Synthes, USA). In the logistic regression analysis, matching for the POLARSTEM was associated with age but not with sex or height. Conversely, for MetaFix and Corail, stem matching was associated with sex and height.
UNASSIGNED: Anthropometric hip measurements vary among individuals, and variables such as age, sex, and height must be considered during preoperative planning and implant selection to avoid leg length discrepancy. Additional studies, including different implants, are required to guide surgeons in selecting a femoral stem that best matches the patient\'s native hip.
