Objective To investigate the treatment effect of the intra-articular calcaneal fractures with heel bone of the lateral extension L-shape incision and locking plate. Methods The lateral extension L-shape incision and locking plate internal fixation was used to treat 32 cases(34 feet) of intra-articular calcaneal fractures. Results The 32 ca-ses received follow-up time of 8~14 (9.2 ± 1.1) months. No postoperative edge delayed healing of incision, skin flap necrosis occurred. Fractures were healed in 12~24 weeks. Gissane angles were restored from preoperative 65°~87° (72.5° ± 9.5°) to postoperative 113° ~ 135°(120° ± 11°), B?hler angles were restored from preoperative-8°~16° (6.2°± 9.4°) to postoperative 20°~38° (24.5°± 9.3°). At last follow-up,according to Maryland foot function criteria of curative effect:excellent 20 feet,good 12 feet,fair 2 feet,excellent-good rate was 94.1%. Con-clusions The right surgery time, good fracture reduction, heel bone lateral extension L-shape incision and locking plate can obtain satisfactory curative effect for treatment of intra-articular calcaneal fracture.%目的 探讨跟骨外侧延长L形切口锁定钢板治疗跟骨关节内骨折的效果.方法 对32例(34足) 跟骨关节内骨折患者行跟骨外侧延长L形切口锁定钢板内固定治疗.结果 32例均获得随访,时间8 ~14 (9.2 ± 1.1)个月.未发生切口延迟愈合、皮瓣边缘坏死.骨折均愈合,时间12~24周.Gissane角由术前的65°~87°(72.5°± 9.5°)恢复至113° ~135°(120° ± 11°),B?hler角由术前的-8° ~16°(6.2° ± 9.4°)恢复至20°~38°(24.5°± 9.3°).末次随访时,根据Maryland足功能评分标准评定疗效:优20足,良12足,中2足,优良率为94.1%.结论 手术时机合适,骨折良好复位,跟骨外侧延长L形切口锁定钢板治疗跟骨关节内骨折可获得满意疗效.
