■我们旨在探索四个皮质中早期PVR与愈合指数(HI)的关联,延长指数(LI),骨愈合和不愈合组的外固定器指数(EFI)。
■共有52名患者,包括39名骨愈合和13名骨不愈合受试者,在这项研究中被招募。研究了各组四个皮质的一般特征和PVR。之后,早期PVR在四个皮质中,包括中间,横向,前,和后侧,进行了比较。最后,四个皮质中早期PVR与HI的关联,LI,和EFI也被调查。
■这些患者的一般特征是一致的,除HI(31.54±12.24vs.45.08±27.10,P=0.018)和EFI(57.63±18.15vs.71.29±24.60,P=0.046)。骨愈合组再生骨痂的生长不对称(后PVR似乎生长更快),而骨不愈合组无统计学差异。此外,骨愈合组后PVR明显高于骨不愈合组(第1个月:0.96±0.17vs.0.86±0.06,p=0.047;第二个月:0.98±0.14vs.0.89±0.09,p=0.041;第三个月:1.00±0.12vs.0.92±0.09,p=0.039)。最重要的是,后部PVR与HI呈负相关,LI,和EFI(第一个月:r=-0.343,p=0.041;r=-0.346,p=0.042;r=-0.352,p=0.041;第二个月:r=-0.459,p=0.004;r=-0.277,p=0.101;r=-0.511,p=0.002;第三个月:r=-0.518,p=0.001,骨)分别。然而,这一发现在骨不愈合组中丢失.
■早期后皮质PVR的生长速度似乎快于内侧,横向,和骨结合组的前侧,这代表了一种不对称的发展模式。此外,后皮质PVR与HI呈负相关,LI,还有EFI,分别。后皮质PVR可能是DO检测过程中一种新颖可靠的检测指标。
UNASSIGNED: We aimed to explore the associations of the early PVR in four cortices with Healing Index (HI), Lengthening Index (LI), and External Fixator Index (EFI) in the bone union and non-union groups.
UNASSIGNED: A total of 52 patients, including 39 bone union and 13 bone non-union subjects, were recruited in this study. The general characteristics and PVR in four cortices in each group were explored. Afterward, the early PVR in four cortices, including medial, lateral, anterior, and posterior sides, were compared. Finally, the associations of the early PVR in four cortices with HI, LI, and EFI were also investigated.
UNASSIGNED: The general characteristics of these patients were consistent, except for HI (31.54 ± 12.24 vs. 45.08 ± 27.10, P = 0.018) and EFI (57.63 ± 18.15 vs. 71.29 ± 24.60, P = 0.046). The growth of regenerated callus was asymmetrical in the bone union group (the posterior PVR seems to grow faster), whereas no statistical difference was obtained in the bone non-union group. Furthermore, the posterior PVR in the bone union group was significantly higher than that in the bone non-union group (the first month: 0.96 ± 0.17 vs. 0.86 ± 0.06, p = 0.047; the second month: 0.98 ± 0.14 vs. 0.89 ± 0.09, p = 0.041; the third month: 1.00 ± 0.12 vs. 0.92 ± 0.09, p = 0.039). Most importantly, the posterior PVR was inversely associated with HI, LI, and EFI (the first month: r = -0.343, p = 0.041; r = -0.346, p = 0.042; r = -0.352, p = 0.041; the second month: r = -0.459, p = 0.004; r = -0.277, p = 0.101; r = -0.511, p = 0.002; the third month: r = -0.479, p = 0.003; r = -0.398, p = 0.018; r = -0.551, p = 0.001) in the bone union group, respectively. However, this finding was lost in the bone non-union group.
UNASSIGNED: The early posterior cortex PVR seems to grow faster than the medial, lateral, and anterior sides in the bone union group, which represents an asymmetrical development pattern. Moreover, the posterior cortex PVR was negatively associated with HI, LI, and EFI, respectively. The posterior cortex PVR may be a novel and reliable detection index in the process of DO.
