Analysis of the difference between the appearance and the bony structure in the polysyndactyly of the fifth toe fused with the fourth toe / 中华整形外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate difference between the appearance and the bony structure in the polysyndactyly of the fifth toe fused with the fourth toe.</p><p><b>METHODS</b>From Jan. 2009 to Jan. 2014, 54 patients (65 feet) with polysyndactyly of the fifth toe fused with the fourth toe were treated. The appearance, X-ray and intraoperative finding were recorded and compared to classify the deformity. Then the extra toe was excised and syndactyly was separated. The malalignment and brachydactyly of the sixth toes were corrected simultaneously.</p><p><b>RESULTS</b>According to the bone and joint type, the fifth toes were neoplastic toes without joints in 17 feet, or had poor bony and joint alignment with the sixth toes in 48 feet. So the fifth toes were excised in all the cases. The patients were followed up for 1 month to 4 years. The oblique deformity of sixth toes were corrected completely with improved length.</p><p><b>CONCLUSIONS</b>The polysyndactyly of the fifth toe fused with the fourth toe should be classified to design the excised toe (usually fifth toe) and correction procedure. The appearance and bony joint recovery are both important.</p>
