Objective: To investigate and evaluate the effectiveness of the distal radius microplate locking plate for the treatment of displaced fracture of medial clavicle.
Methods: Between January 2013 and June 2017, 18 cases of obvious displaced fracture of medial clavicle were treated with distal radius microlocking plate. There were 10 males and 8 females, with an average age of 51.4 years (range, 18-88 years). Causes of injury included traffic accident injury in 15 cases, heavy object injury in 3 cases; all of them were closed injury. According to Edinburgh classification, 15 cases were ⅠB1 type and 3 cases were ⅠB2 type. Fracture displacement was 12-21 mm (mean, 16.3 mm). The time from injury to operation was 3-7 days (mean, 4.3 days). After operation, the clinical healing and complications of fracture were observed, and shoulder function was evaluated according to Rockwood's scoring criteria.
Results: No incisional infection, neurovascular injury, or other early complications occurred. All 18 patients were followed up 8-15 months (mean, 12 months). All fractures reached clinical osseous union, and the healing time was 8-24 weeks (mean, 16.6 weeks). Postoperative plate loosening occurred in 1 case, which was removed surgically, while other patients did not suffer from complications such as bone nonunion, displacement, internal fixator loosening, and loss of reduction. At last follow-up, according to Rockwood's scoring criteria, the results were excellent in 12 cases and good in 6 cases.
Conclusion: The distal radius microplate locking plate is effective for the treatment of displaced medial clavicle fracture, which has few complications, and is feasible for early functional exercise, and is helpful for the recovery of shoulder joint function.
目的: 探讨桡骨远端微型锁定钢板治疗明显移位的锁骨内侧端骨折临床疗效。.
方法: 2013 年 1 月—2017 年 6 月采用桡骨远端微型锁定钢板治疗明显移位的锁骨内侧端骨折 18 例。男 10 例，女 8 例；年龄 18～88 岁，平均 51.4 岁。致伤原因：交通事故伤 15 例，重物砸伤 3 例；均为闭合性损伤。骨折根据 Edinburgh 分型：ⅠB1 型 15 例，ⅠB2 型 3 例。骨折移位 12～21 mm，平均 16.3 mm。受伤至手术时间 3～7 d，平均 4.3 d。术后观察患者骨折临床愈合、并发症发生情况，按 Rockwood 等的评分标准评定肩关节功能。.
结果: 术后均未出现切口感染、神经血管损伤等早期并发症。18 例患者均获随访，随访时间 8～15 个月，平均 12 个月。骨折均达到临床骨性愈合，愈合时间 8～24 周，平均 16.6 周。术后出现钢板松动 1 例，予以手术拆除；其余患者未出现骨不连、移位、内固定物松动及复位丢失等并发症。末次随访时按 Rockwood 等的评分标准评价肩关节功能，获优 12 例、良 6 例。.
结论: 桡骨远端微型锁定钢板治疗明显移位的锁骨内侧端骨折可获得较好疗效，并发症少，可行早期功能锻炼，有助于肩关节功能恢复。.
