股骨转子间杵臼状外展截骨术治疗儿童髋内翻

Ball and Socket Valgus Osteotomy in Intertrochanteric Region of Femur for Coxa Vara in Children.

本文报告采用股骨转子间杵臼状外展截骨术治疗儿童髋内翻１０例（１４髋）。年龄为６～１２岁。截骨处均在８周愈合。８例（１２髋）随访３～１０年（平均４年２月），均取得满意疗效。作者认为，本术式方法简单，截骨处接触面大，截骨后稳定，愈合快，畸形矫正满意，疗效好。对股骨颈干角小于１１０°者均可采用本法矫正，较大儿童颈干角应矫正至１３５°～１４５°。截骨后应以钢板螺丝钉内固定，并用髋人字石膏固定６～８周。

Ball and socket valgus osteotomy in intertrochanteric region of femur for correction of coxa vara in 10 children(14 hips)with ages ranging from 6 to 12 years is reported.Bony union in the areas of osteotomy was obtained in 8 weeks in all patients.Eight patients(12 hips) were followed up for a mean of 4 years and 2 months(range,3 10 years)with satisfactory results.The authors feel that this procedure is a simple,effective method whereby the area of contact between the fragments could be increased and greater stability achieved,and earlier bony union is more likely to occur,hence excellent correction of deformity.Correction of coxa vara by this method is indicated when the neck shaft angle is 110 degrees or less.The neck shaft angle should be cerrected to approximately 135 to 145 degrees for elder children.Internal fixation with screw plate is recommended after osteotomy reinforced by a spica cast worn for 8 weeks.
