Patterns of growth and development are presented for 33 patients with congenital posteromedial bowing of the tibia and fibula. The bowing is accompanied by shortening of the tibia and fibula, an initial calcaneovalgus deformity of the foot, and a decrease in ankle motion that does not improve with age. In general, the greater the initial bowing, the greater the ultimate extremity length discrepancy. The proportionate length differences between the normal and the bowed tibiae remained stable after the age of 12 months. This allowed a projection of anticipated extremity length discrepancy at maturity and a determination of the proper treatment. At birth the bowing varied from approximately 25 to 70 degrees, and at maturity the absolute tibial length discrepancies varied from 3.3 to 6.9 cm. Both the posterior and the medial components of the bow became markedly reduced with increasing age, but a mild residual medial portion of the bow remained. Soft tissue enlargement was observed in the posterior aspect of the affected legs in early life and developed to a relative muscle atrophy in later years.
本文介绍了33例先天性胫腓骨后内侧弓形弯曲患者的生长发育模式。这种弓形弯曲伴有胫腓骨缩短、足部最初的跟骨外翻畸形以及踝关节活动度随年龄增长而未改善的情况。一般来说，最初的弓形弯曲越大，最终的肢体长度差异就越大。正常胫骨和弓形弯曲胫骨之间的比例长度差异在12个月龄后保持稳定。这使得能够预测成熟时预期的肢体长度差异，并确定适当的治疗方法。出生时，弓形弯曲角度约为25度至70度，成熟时胫骨绝对长度差异为3.3厘米至6.9厘米。随着年龄增长，弓形弯曲的后部和内侧部分均明显减小，但仍残留轻度的内侧弓形部分。在生命早期，患侧腿部后侧观察到软组织肿大，在后期发展为相对的肌肉萎缩。
