PURPOSE
To evaluate whether characteristics such as age, height, weight, sex, or body mass index affected the distal tibial dimensions and radius of curvature (ROC) of a potential donor for anterior glenoid augmentation.
METHODS
A retrospective review of magnetic resonance imaging of ankles without bony trauma was performed, and the anteroposterior (AP) and medial-lateral (ML) distances and ROC of the tibial plafond articular surface were measured. Demographic characteristics, including age, sex, height, weight, and body mass index, were recorded.
RESULTS
A total of 141 imaging studies were included (73 men and 68 women; average age, 38.2 ± 12.65 years). All potential specimens accommodated harvest of a 10 × 22-mm distal tibial allograft bone block. Men had greater ML (42.74 cm [95% confidence interval (CI), 42.09-43.39 cm] vs 38.01 cm [95% CI, 37.30-38.72 cm]; P < .001) and AP (38.16 cm [95% CI, 37.47-38.85 cm] vs 34.57 cm [95% CI, 33.97-35.17 cm]; P < .001) dimensions. Significant moderately positive correlations were found for AP dimensions with height (r = 0.584, P < .001) and weight (r = 0.383, P < .001) and for ML dimensions with height (r = 0.711, P < .001) and weight (r = 0.467, P < .001). ROC was positively correlated with height (r = 0.509, P < .001) and weight (r = 0.294, P < .001). Patient age was not related to either the AP or ML distal tibial dimensions or ROC.
CONCLUSIONS
After magnetic resonance imaging analysis, all potential donors permitted harvest of a standard-sized distal tibial allograft irrespective of sex or common anthropometric measures, and 85.8% showed distal tibial morphology acceptable for glenoid augmentation. AP and ML graft dimensions and ROC correlated significantly with height and weight.
LEVEL OF EVIDENCE
Level II, diagnostic study.
目的
评估年龄、身高、体重、性别或体重指数等特征是否会影响前肩胛盂增强用供体的胫骨远端尺寸和曲率半径（ROC）。
方法
对无骨创伤的踝关节磁共振成像进行回顾性分析，并测量距骨关节面的前后（AP）和内外（ML）距离及 ROC。记录人口统计学特征，包括年龄、性别、身高、体重和体重指数。
结果
共纳入 141 项影像学研究（男性 73 例，女性 68 例；平均年龄 38.2±12.65 岁）。所有潜在标本均可采集 10×22mm 胫骨远端同种异体骨块。男性的 ML（42.74cm[95%置信区间（CI），42.09-43.39cm]）和 AP（38.16cm[95%CI，37.47-38.85cm]）尺寸均大于女性（分别为 38.01cm[95%CI，37.30-38.72cm]和 34.57cm[95%CI，33.97-35.17cm]；P<0.001）。AP 尺寸与身高（r=0.584，P<0.001）和体重（r=0.383，P<0.001）呈显著中度正相关，ML 尺寸与身高（r=0.711，P<0.001）和体重（r=0.467，P<0.001）呈显著中度正相关。ROC 与身高（r=0.509，P<0.001）和体重（r=0.294，P<0.001）呈正相关。患者年龄与 AP 或 ML 胫骨远端尺寸或 ROC 均无相关性。
结论
磁共振成像分析后，所有潜在供体均允许采集标准大小的胫骨远端同种异体移植物，无论性别或常见的人体测量指标如何，85.8%的供体显示胫骨远端形态适合肩胛盂增强。AP、ML 移植物尺寸和 ROC 与身高和体重显著相关。
