Objective To study the indications, methods, and therapeutic effect of absorbable rib-connecting-pins fixation in the treatment of multi ple rib fractures. Methods Between March 2007 and September 2009, 40 patients with multiple rib fractures received internal fixation with absorbable rib-connecting-pins, including 8 one-side flail chest and 1 twoside flail chest. There were 32 males and 8 females with an average age of 39.8 years (range, 25-72 years). The injury was caused by traffic accident in 32 cases, fall ing from height in 6 cases, and blunt hitting in 2 cases. Preoperatively, imaging data of the chest X-ray or spiral CT three-dimensional (3D) examination showed that all patients had multiple ribs fractures and displacement. The number of fractured ribs was 4-10 (median, 6), and the fracture location ranged from the 2nd to the10th ribs. Of them, 28 cases were accompanied by hemathorax, pneumathorax or hemopneumothorax; 5 cases by thoracic organ injury; and 10 cases byother part trauma. The time from injury to hospital ization was less than 1 day in 26 cases, 1-3 days in 12 cases, and 3-6 days in 2 cases, and the time from hospital ization to operation was 3 hours to 3 days (mean, 1.2 days). Results The median fixation rib number was 5 (range, 3-8). The mean operative time, the time in bed, and hospital ization days were 32 minutes (range, 15-50 minutes), 4.5 days (range, 2-7 days), and 11.2 days (range, 5-18 days), respectively. All incisions healed by first intention. No pulmonary infection, pulmonary atelectasis, intrathoracic infection or other compl ications occurred. All cases were followedup 6-12 months (mean, 8 months). PaO2 [(86.6 ± 2.2) mmHg (1 mm Hg=0.133 kPa)] and SpO2 (97.2% ± 0.6%) at 2 hours after operation were obviously improved when compared with preoperative ones [PaO2 (53.6 ± 4.7) mm Hg and SpO2 (86.2% ± 1.8%)], showing significant differences (t=2.971, P=0.005; t=2.426, P=0.020). The chest X-ray films or spiral CT 3D indicated that fracture of rib healed within 3-6 months (mean, 4.5 months) after operation. Conclusion Severe collapsed chest wall orflail chest caused by fracture of multiple ribs should be treated by absorbable rib-connecting-pins, which is a simple, firm, and effective method.
目的探讨可吸收肋骨钉与记忆合金接骨板内固定两种方法治疗多发性肋骨骨折的效果。 方法回顾性分析2009年1月至2014年1月在上海市第六人民医院胸外科行手术内固定的胸部外伤致多根多处肋骨骨折患者321例的临床资料，其中可吸收肋骨钉组70例，其中男62例、女8例，年龄（48.54±9.74）岁；记忆合金接骨板组251例，其中男187例、女64例，年龄（51.44±10.22）岁。分析两组患者疗效差异。 结果两组患者术前疼痛评分（7.74±0.89 vs.7.66±0.92）、术后疼痛评分（3.80±0.79 vs.3.82±0.85），术后胸腔引流时间[（6.00±2.84）d vs.（5.68±2.98）d]差异均无统计学意义（P>0.05）。记忆合金接骨板组住院时间[（20.06±7.39）d vs.（17.77±7.68）d]，及手术时间（101.29±30.67）min vs.（71.95±29.50）min]均短于可吸收肋骨钉组，且差异有统计学意义（P＜0.05)。术后3个月随访复查胸部X线，两组患者骨折再移位差异无统计学意义。 结论可吸收肋骨钉与记忆合金接骨板均是治疗多发性肋骨骨折较理想的术式，记忆合金接骨板手术操作更为简单，可吸收肋骨钉手术无需在体内留置金属内固定装置，但固定强度较接骨板略差，应根据情况选择合适的内固定方法。
