摘要
前臂的尺骨、橈骨因先天性缺陷、骨髓炎或良性瘤及外傷等成因造成前臂骨頭一方的損，由於兩骨生長速度不同，在成長的過程中會造成前臂及手的畸形甚至關節脫位的現象，在早期時骨頭缺損可以骨移植等方法補救，可是病人若疏忽治療，長大成人則前臂的畸形會相當明顯，前臂的活動穩定性亦嫌不夠，此時可採用單骨前臂法手術利用尺骨近端接近於橈骨的遠端，將兩骨併成一骨，此手術會喪失前臂旋轉功能，但病人可利用肩關節及腕關節來補償，對外觀及前臂穩定度上均大為改善，握力也增加。 本院由1984至1985一共施行二例單骨前臂手術，病因均是因為小孩時之慢性骨髓炎所引起，經行單骨前前手術法後，術後均有令人滿意結果，我們將詳加討論此手術之適應症及優劣點。

A gap defect in the shaft of radius of radius or ulna in children caused forearm deformity eventually due to the unequal growth of the two forearm bones. When instability and bone defect would not be corrected by bone grafting or other reconstrustive procedures, one-bone forearm operation was a salvage procedure which provided a stable forearm. Its merits included increased stability and strength of forearm, better hand function and good cosmesis. The disadvantage of one-bone forearm was loss of rotation of the forearm which could be compensated by the motion of the shoulder. Two cases with one-bone forearm were presented with satisfaftory good cosmetic and functional results.
