A retrospective analysis was performed to establish the prevalence and clinical significance of limb length discrepancy in congenital talipes equinovarus. Of 536 patients with the diagnosis of congenital talipes equinovarus, 259 were unilaterally affected and 277 bilaterally affected. Fifty-eight patients were identified with limb length discrepancy greater than 0.5 cm. Forty-six patients had unilateral foot deformity and in 12 cases that was bilateral. This represented a prevalence of documented limb length discrepancy in 18% of unilateral cases and 4% of bilateral cases. The discrepancy resulted in a surgical procedure to equalize the limb lengths in fourteen unilateral cases (5%). A further six unilateral cases were deemed likely to require limb length equalization, increasing the rate to 8%. Only three bilateral cases required or will require surgery for equalization (1%). There was a weak but significant correlation between the number of operations undergone and the magnitude of discrepancy. The tibia was as important in its contribution to the shortening in these patients as the foot. A total of 89% unilateral cases studied had at least 0.3 cm of tibial shortening and 43% had ipsilateral femoral shortening of at least 0.3 cm.
进行了一项回顾性分析，以确定先天性马蹄内翻足肢体长度差异的患病率及其临床意义。在536例诊断为先天性马蹄内翻足的患者中，259例为单侧受累，277例为双侧受累。58例患者被确定存在大于0.5 cm的肢体长度差异。46例患者为单侧足部畸形，其中12例为双侧畸形。这表明单侧病例中记录的肢体长度差异患病率为18%，双侧病例为4%。在14例单侧病例（5%）中，差异导致了平衡肢体长度的手术。另有6例单侧病例被认为可能需要平衡肢体长度，使这一比例增至8%。只有3例双侧病例需要或将要进行平衡手术（1%）。手术次数与差异程度之间存在微弱但显著的相关性。在这些患者中，胫骨对缩短的影响与足部同样重要。在研究的单侧病例中，共有89%至少有0.3 cm的胫骨缩短，43%同侧股骨至少有0.3 cm的缩短。
