进行性塌陷足畸形(PCFD)是一种复杂的三维畸形，伴有不同程度的后足外翻、前足外展和足中内翻。这项研究的第一个目的是对接受扁平足矫形术的有症状的PCFD患者和对照组之间的距骨形态进行三维分析。第二个目的是调查个体距骨形态是否对扁平足矫形手术的成功率有影响。我们回顾了2008-2018年间在我们诊所接受跟骨外侧延长矫正PCFD的所有患者。在术前和术后的X线片上评估平足的X线参数。此外，使用计算机断层扫描(CT)数据生成了TALI的三维表面模型。将44只扁平足的距骨形态与50名无足或踝关节疼痛的对照组的3-D模型进行比较。在人口统计方面，这些群体具有可比性。PCFD组和对照组的距骨形态在多个方面存在显著差异。足底屈曲(2 2.3°比2 6°；p = 0.0 2)和距骨头相对于身体的内侧偏斜(31.7°和33.5°；p = 0.0 4)较对照组增加2.6°。此外，PCFD的特征是距下关节外翻(相差4.6°；p = 0.0 1)。所有病例均获得满意矫正，距跖角和距舟未覆盖角分别改善5.6° ± 9.7(p = 0.0 2)和9.9° ± 16.3(p = 0.001)。在距骨形态与术后一年矫正或丧失矫正之间没有发现统计学意义上的相关性。上述不同的形态特征可能是PCFD进展的因素或危险因素。然而，尽管距骨形态多样，与对照组相比有所不同，但跟骨延长截骨术的手术结果并未受到影响。三.
Progressive collapsing foot deformity (PCFD) is a complex 3-dimensional (3-D) deformity with varying degrees of hindfoot valgus, forefoot abduction, and midfoot varus. The first aim of this study was to perform a 3-D analysis of the talus morphology between symptomatic PCFD patients that underwent operative flatfoot correction and controls. The second aim was to investigate if there is an impact of individual talus morphology on the success of operative flatfoot correction. We reviewed all patients that underwent lateral calcaneal lengthening for correction of PCFD between 2008 and 2018 at our clinic. Radiographic flatfoot parameters on preoperative and postoperative radiographs were assessed. Additionally, 3-D surface models of the tali were generated using computed tomography (CT) data. The talus morphology of 44 flatfeet was compared to 3-D models of 50 controls without foot or ankle pain of any kind. Groups were comparable regarding demographics. Talus morphology differed significantly between PCFD and controls in multiple aspects. There was a 2.6° increased plantar flexion (22.3° versus 26°; p = 0.02) and medial deviation (31.7° and 33.5°; p = 0.04) of the talar head in relation to the body in PCFD patients compared to controls. Moreover, PCFD were characterized by an increased valgus (difference of 4.6°; p = 0.01) alignment of the subtalar joint. Satisfactory correction was achieved in all cases, with an improvement of the talometatarsal-angle and the talonavicular uncoverage angle of 5.6° ± 9.7 (p = 0.02) and 9.9° ± 16.3 (p = 0.001), respectively. No statistically significant correlation was found between talus morphology and the correction achieved or loss of correction one year postoperatively. The different morphological features mentioned above might be contributing or risk factors for progression to PCFD. However, despite the variety of talar morphology, which is different compared to controls, the surgical outcome of calcaneal lengthening osteotomy was not affected. III.
