Malunion is the most common complication of the distal radius with many modalities of treatment available for such a problem. The use of bone grafting after an osteotomy is still recommended by most authors. We hypothesised that bone grafting is not required; fixing the corrected construct with a volar locked plate helps maintain the alignment, while metaphyseal defect fills by itself. Prospectively, we performed the procedure on 30 malunited dorsally-angulated radii using fixed angle volar locked plates without bone grafting. At the final follow-up, 22 wrists were available. Radiological evidence of union, correction of the deformity, clinical and functional improvement was achieved in all cases. Without the use of bone grafting, corrective open wedge osteotomy fixed by a volar locked plate provides a high rate of union and satisfactory functional outcomes.
畸形愈合是桡骨远端最常见的并发症,针对这一问题有多种治疗方式。大多数作者仍建议在截骨术后使用骨移植。我们假设不需要骨移植;用掌侧锁定钢板固定矫正后的结构有助于维持对线,而干骺端缺损会自行填充。我们前瞻性地对30例背侧成角畸形愈合的桡骨使用掌侧锁定钢板进行固定,未进行骨移植。在最后一次随访时,有22例手腕可供评估。所有病例均获得了愈合的影像学证据、畸形矫正以及临床和功能改善。不使用骨移植,通过掌侧锁定钢板固定的矫正性开放楔形截骨术可实现高愈合率和满意的功能结果。
