背景肢体长度不等的患者表现出步态模式的改变或跛行。本前瞻性研究的目的是比较客观的步态参数较短的下肢与较长的下肢延长前和延长后，并比较这些数据与一组20名受试者谁没有肢体长度disciplines.Methods：18例肢体长度均衡到1厘米以内。结果：延长前短肢与长肢的平均站立时间相差12%，延长后短肢与长肢的平均站立时间相差2.4%;延长前后的测量值差异有显著性（p < 0.001），无肢体不等长的患者的肢体之间的站立时间差异为2%，术前，短肢的平均第二峰值为体重的104%，而长肢为体重的116%;这种差异是显著的（p < 0.001）。延长后，短肢的平均第二峰值增加到体重的113%。延长前后第二个峰值的平均值差异显著（p < 0.001），在现有数据范围内，短肢和长肢延长后第二峰值的平均值无显著性差异（p = 0.12）结论：这项研究表明，肢体长度不一致的患者的短肢延长可以使可量化的站立参数的对称性正常化，并消除跛行。
Background Patients who have limb-length discrepancy demonstrate an altered gait pattern or a limp. The purpose of this prospective study was to compare the objective gait parameters for the shorter lower limb with those for the longer lower limb before and after lengthening and to compare these data with those for a group of twenty subjects who had no limb-length discrepancy.Methods: Eighteen patients had equalization of limb length to within one centimeter. We analyzed the stance time, the second peak of the vertical ground-reaction-force vector, and the rate of loading with use of two force-plates arranged in a series.Results: The difference in the mean stance times between the shorter and longer limbs before lengthening was 12 percent, whereas that after lengthening was 2.4 percent; the difference between the values before and after lengthening was significant (p < 0.001), The difference in the stance times between the limbs of the patients who did not have limb-length discrepancy was 2 percent, Preoperatively, the mean second peak was 104 percent of body weight for the shorter limb compared with 116 percent for the longer limb; this difference was significant (p < 0.001). After lengthening, the mean second peak for the shorter limb increased to 113 percent of body weight. The difference in the means for the second peak before and after lengthening was significant (p < 0.001), With the numbers available, no significant difference was detected in the means for the second peak between the shorter and longer limbs after lengthening (p = 0.12).Conclusions: This study shows that lengthening of the shorter limb of patients who have limb-length discrepancy can normalize symmetry of quantifiable stance parameters and eliminate a limp.
