Fifty-one patients with dislocated lateral malleolar fractures took part in this prospective randomized study. Active ankle movements with weight bearing in an orthosis were compared with active ankle movements without weight bearing using a dorsal splint. By using cerclage, staples, and pins (Cedell 1967), an exact reconstruction of the ankle mortise was achieved in 44/51 ankles. Radiographic and stereophotogrammetric analyses at 3 months showed no redislocation and only small movements in the ankle mortise. Better loaded dorsal flexion capacity at 3 months was found in the orthosis group. This study was designed as the second part of a consecutive study. In the first part, early or late weight bearing without ankle exercises was compared (Ahl et al. 1986). The results from the two consecutive parts indicate that active ankle movements in combination with weight bearing facilitate and improve the rehabilitation following operation for an ankle fracture.
51例伴有外踝骨折脱位的患者参与了这项前瞻性随机研究。将在矫形器中负重时的主动踝关节活动与使用背侧夹板不负重时的主动踝关节活动进行了比较。通过使用环扎、钉合和克氏针（Cedell，1967年），51例踝关节中的44例实现了踝关节榫眼的精确重建。3个月时的影像学和立体摄影测量分析显示无再脱位，踝关节榫眼仅有微小活动。矫形器组在3个月时发现有更好的负重背屈能力。本研究被设计为一项连续性研究的第二部分。在第一部分中，比较了早期或晚期不负重时的踝关节活动（Ahl等人，1986年）。这两个连续部分的结果表明，主动踝关节活动结合负重有助于并改善踝关节骨折术后的康复。
