To gain a wider operation field, ribs often are fractured as the intercostal retractor is expanded. Thoracotomy through the periosteal bed and other procedures have been performed to prevent rib fractures, and rib resections occasionally have been required.
We designed a poly-L-lactide costal coaptation pin. We used this pin in 184 thoracotomies and carried out long-term observation after insertion to evaluate its clinical efficacy and safety. Postoperative observation periods ranged from 1 to 58 months (mean +/-standard error, 21.6+/-1.2 months). We evaluated the costal pin according to its degree of fixation, categorizing it as "good," "fair," or "poor" in this respect. We also judged its lateral shift.
We judged fixation as "good" in 130 cases (70.7%), and found no lateral shift in 103 cases (56%). Our overall evaluation indicated satisfactory results in 172 cases (93.5%).
Rib fixation was secured in nearly all cases, and no side effects were encountered. We can confirm that the poly-L-lactide costal coaptation pin is a highly effective and safe device.
为获得更广阔的手术视野，在肋间牵开器撑开时肋骨常发生骨折。已采用经骨膜床开胸术及其他术式来预防肋骨骨折，偶尔还需要进行肋骨切除术。
我们设计了一种聚-L-乳酸肋骨接合针。我们在184例开胸手术中使用了这种针，并在插入后进行长期观察以评估其临床疗效和安全性。术后观察期为1至58个月（平均±标准误，21.6±1.2个月）。我们根据肋骨针的固定程度对其进行评估，在这方面将其分为“良好”、“尚可”或“较差”。我们还判断了其侧向移位情况。
我们判定130例（70.7%）的固定为“良好”，103例（56%）未发现侧向移位。我们的总体评估表明172例（93.5%）结果令人满意。
几乎在所有病例中肋骨固定都很牢固，且未出现副作用。我们可以确认聚-L-乳酸肋骨接合针是一种高效且安全的器械。
