回顾性观察40例（平均年龄22.8岁）踝关节移位骨折患者，通过临床检查和足底压力分布测量，确定踝关节骨折手术治疗是否成功导致步态对称，以及骨折类型和临床结局是否与个体差异有关。平均随访18.5个月（范围：12-36个月）。步态的偏差使用总冲量的对称指数进行量化。使用临床评分，6名患者的结果不满意，其余34名患者的结果满意。在健康对照组（-0.31%，n = 90）的范围内，好结果（-1.1%）和差结果（-2.3%）的对称指数下降，表明创伤后实现了整体步态对称。足底压力分布表现出明显的负荷不对称性。结果良好的患者受伤腿外侧前足的负荷增加，结果不良的患者跖骨头下的压力降低。虽然这些不对称性与骨折类型和临床结果无关，但这些发现可能说明了创伤后踝关节改变后用于恢复步态对称性的补偿机制。
Forty patients (mean age, 22.8 years) admitted for displaced ankle fracture were observed retrospectively to determine by clinical examination and measurement of plantar pressure distribution whether successful surgical treatment of ankle fractures led to gait symmetry, and whether intraindividual differences were related to fracture type and clinical outcome. The mean followup was 18.5 months (range, 12–36 months). The deviation of gait was quantified using a symmetry index of the total impulse. Using a clinical score, 6 patients had unsatisfactory results, and the remaining 34 had satisfactory results. The symmetry index of the good (−1.1%) and the poor results (−2.3%) decreased in the range of a healthy control group (−0.31%, n = 90), indicating that overall gait symmetry was achieved after trauma. The plantar pressure distribution showed significant load asymmetries. There was increased loading in the lateral forefoot of the injured leg in patients with good results and decreased pressure under the metatarsal heads of patients with bad results. Although those asymmetries were related neither to fracture type nor clinical outcome, the findings may illustrate compensation mechanisms that are used to regain gait symmetry after ankle alteration by trauma.
