Sixty-one idiopathic clubfeet in 46 patients of an older population were treated by one-stage posteromedial release. Follow-up roentgenograms revealed dorsal subluxation of the tarsal navicular in 43% of the clubfeet. This abnormality is probably due to both closed manipulation and casting, and improper positioning of the navicular during posteromedial release. However, dorsal navicular subluxation did not adversely affect the results of treatment observed over the follow-up period that averaged nearly 6 1/2 years. Medial subluxation of the navicular was associated with unsatisfactory results, whereas a centrally located or laterally subluxed navicular generally produced good or excellent results. Other abnormalities of the navicular noted included wedging and avascular necrosis. The long-term consequences of these various abnormalities of the roentgenographic appearance and position of the navicular are not known.
对46例老年患者的61例特发性马蹄内翻足进行了一期后内侧松解治疗。随访X线片显示，43%的马蹄内翻足出现舟骨背侧半脱位。这种异常可能是由于闭合手法复位和石膏固定，以及后内侧松解过程中舟骨位置不当所致。然而，舟骨背侧半脱位在平均近6.5年的随访期内并未对治疗结果产生不利影响。舟骨内侧半脱位与不满意的结果相关，而位于中央或外侧半脱位的舟骨通常产生良好或优异的结果。舟骨的其他异常包括楔形变和缺血性坏死。舟骨X线表现和位置的这些各种异常的长期后果尚不清楚。
