PHILOS钢板经前外侧入路结合MIPPO技术治疗肱骨近端合并肱骨中上段骨折临床疗效

目的探讨长肱骨近端锁定钢板系统(PHILOS)经前外侧入路使用经皮微创技术(MIPPO)治疗肱骨近端骨折合并同侧肱骨中上端骨折临床疗效观察。方法自2015年1月至2019年1月收治25例肱骨近端骨折合并同侧肱骨干中上段骨折,其中男16例,女9例;年龄21～72岁,平均为61.5岁。对患者手术时间、术中出血量、骨折愈合、并发症及术后12月肩肘关节功能进行评价。结果 25例患者均获得随访,随访时间12月～24月,平均为18.2月,手术时间70～126 min,平均为107.8 min,术中出血量100～240 mL,平均为173.6 mL,骨折均取得愈合,愈合时间为14～28周,平均为20.3周。1例患者术后出现拇指背伸活动受限,3月后恢复,1例患者钢板位置放置较高出现肩峰撞击,内固定取出后症状改善。术后12月随访肩关节功能优17例,良7例,一般1例,优良率96%。术后12月肘关节功能优23例,良2例,优良例100%。结论运用PHILOS钢板结合经皮微创MIPPO技术通过前外侧入路闭合复位固定肱骨近端骨折合并肱骨中上段骨折,具有术中损伤小,出血量少,节省手术时间,骨折愈合率高,术后肩肘关节恢复满意等优点。

CLINICAL EFFECT OF PHILOS PLATE THROUGH ANTERIOR-LATERAL APPROACH COMBINED WITH MIPPO TECHNOLOGY IN THE TREATMENT OF PROXIMAL HUMERUS WITH MIDDLE AND UPPER HUMERUS FRACTURES

Objective: To investigate the clinical efficacy of the proximal humerus locking plate system (PHILOS) through the anterolateral approach using percutaneous minimally invasive technology (MIPPO) for the treatment of proximal humerus fractures combined with ipsilateral middle and upper humerus fractures. Methods: From January 2015 to January 2019, 25 patients with proximal humerus fractures combined with middle and upper humeral shaft fractures were treated, including 16 males and 9 female (21-72 years old with an average of 61.5 years). The operation time, intraoperative blood loss, fracture healing, complications, and shoulder and elbow joint function after 12 months were evaluated. Results: All 25 patients were followed up. The follow-up time was from 12 to 24 months, with an average of 18.2 months. The operation time was 70 to 126 minutes, with an average of 107.8 minutes. The intraoperative blood loss was 100 to 240 ml, with an average of 173.6 ml. All fractures were healed. The healing time was 14-28 weeks, with an average of 20.3 weeks. One patient had limited thumb dorsiflexion postoperatively and recovered 3 months later. One patient had a high shoulder plate and acromion. The symptoms were improved after internal fixation. The follow-up of shoulder function was excellent in 17 cases, good in 7 cases, and fair in 1 case. The excellent and good rate was 96%. 12 months after operation, elbow function was excellent in 23 cases, good in 2 cases, with a good rate of 100%. Conclusion: PHILOS steel plate combined with percutaneous minimally invasive MIPPO technology is used to close and fix the proximal humerus fracture with middle and upper humerus fracture through anterolateral approach. It has small intraoperative injury, less bleeding, saves operation time, and has a high fracture healing rate. Back shoulder and elbow joint recovery is satisfactory.
