摘要:

背景:既往肋骨骨折多主张保守治疗,随着内固定材料学的进展,以及对肋骨损伤研究的深入,开始采用内固定修复肋骨骨折,以期缩短治疗周期,提高患者的生活质量,但是何种内固定方法最佳,目前还存在争论。

目的:总结记忆合金环抱器置入内固定对连枷胸的修复效果。
方法:潜江市中心医院胸外科2008年5月至2011年5月采用记忆合金环抱器置入内固定修复连枷胸患者50例,男39例,女11例;年龄22-67岁,平均42.6岁。致伤原因:车祸伤38例,坠落伤11例,轮胎爆炸伤1例。骨折情况:肋骨骨折数3-11根,平均(6.4±4.3)根,骨折处7-23处,平均(11.2±5.6)处。左侧连枷胸25例,右侧17例,双侧8例。受伤到手术时间2-7 d,平均(3.7±2.2)d。观察呼吸机使用时间、重症监护天数、住院天数、围手术期并发症、骨折复位情况、骨折愈合时间等;并采用目测类比评分法评估患者手术前后胸壁疼痛情况。
结果与结论:患者术后切口均Ⅰ期愈合,均获随访,随访时间13-22个月。未出现术中并发症。内固定后机械辅助通气时间1-3 d,平均(1.8±0.7) d;住重症监护室时间2-5 d,平均(2.6±1.1) d;住院时间12-17 d,平均(14.9±3.1) d;平均目测类比评分由术前(8.1±1.2)分降低到内固定后1 d的(4.9±0.9)分、内固定后1周的(3.2±1.1)分;无内固定失败、松动、切口感染及骨不连,内固定后骨折均达临床愈合,愈合时间2-4个月,平均(3.1±1.2)个月。提示记忆合金环抱器置入内固定是修复连枷胸的有效方法,可以稳定胸壁,减少机械通气时间和与机械通气相关的并发症,减少胸壁畸形以及慢性胸壁疼痛。

Abstract:

BACKGROUND: Previously, many authors advocated that the rib fractures can be treated by conservative method. However, with the progress of internal fixation materials science and in-depth study of the rib injury, many authors have begun to recommend that rib fractures should be treated by internal fixation surgery, which may shorten the treatment period and improve patient’s quality of life. But which is the optimal fixation methods, is still controversial.

OBJECTIVE: To summarize the clinical outcomes of the memory alloy osteosynthesis plate fixation for flail chest injuries.
METHODS: From May 2008 to May 2011, 50 patients with flail chest were treated with memory alloy osteosynthesis plate fixation in Department of Thoracic Surgery, Qianjiang Central Hospital. There are 39 males and 11 females, the mean age was 42.6 years (range 22-67 years). The flail chest injuries were caused by traffic accidents in 38 cases, by falling from height in 11 cases, and by tire blast injury in 1 case. The mean number of rib fractures was 6.4±4.3 (range 3-11); the mean fracture sites were 11.2±5.6 (range 7-23). There were 25 patients with flail chest at left side, 17 cases at right side, and 8 cases at bilateral sides. The mean time from injury to the surgical time was 3.7±2.2 days (range 2-7 days). The length of postoperative ventilator use, postoperative ICU days, length of hospital stay, peripheral complications, fracture reduction and fracture healing time were observed. The chest wall pains before and after surgery were evaluated with the visual analog scale.
RESULTS AND CONCLUSION: All incisions obtained healing by first intention and all patients were followed up for 13-22 months. There were no intraoperative complications. Mean postoperative ventilator days were 1.8±0.7 days (range 1-3 days); mean post-operative ICU days were 2.6±1.1 days (range 2-5 days); mean lengths of hospital stay were 14.9±3.1 days (range 12-17 days); the visual analog scale scores was reduced from preoperative 8.1±1.2 points to 4.9±0.9 points at 1 day post-surgery and 3.2±1.1 points at 1 week post-surgery. No cases of hardware failure, hardware prominence, wound infection, or nonunion were observed. All fractures reached clinical healing, and mean healing time was 3.1±1.2 months (range 2-4 months). The memory alloy osteosynthesis plate fixation is an effective technique for the treatment of flail chest, can provide stability for the injured segments of the chest wall, reduce ventilator time, decrease ventilator-associated complications, reduce deformity, and decrease chronic pain.
