镍钛形状记忆合金环抱接骨板治疗桡骨近端1/3骨折

TREATMENT OF FRACTURES OF PROXIMAL RADIUS WITH Ni-Ti SHAPE MEMORY ALLOY EMBRACING FIXATOR

目的探讨治疗桡骨近端1/3骨折的理想内固定方法。方法2001年8月～2004年4月,采用镍钛形状记忆合金环抱接骨板治疗24例桡骨近端1/3骨折。其中男19例,女5例。年龄16～48岁。摔伤9例,压砸伤5例,交通事故伤4例,直接暴力撞击伤3例,高处坠落伤3例。按照形状记忆合金环抱接骨板的安装方法进行骨折复位内固定。术后定期随访,观察骨折愈合及功能恢复情况。结果所有患者均获随访4～21个月,平均10个月。均无术中、术后并发症,切口期愈合;X线片示骨折均于术后8～12周临床愈合,根据Anderson疗效标准,功能恢复优18例,良5例,可1例,优良率95.83%。结论应用镍钛形状记忆合金环抱接骨板治疗桡骨近端1/3骨折具有创伤小、操作简便安全、固定可靠、组织相容性好、并发症少等优点,有利于促进骨折愈合和肘、腕关节功能康复,是一种治疗桡骨近端1/3骨折的较好方法。

Objective To find out an ideal method of internal fixation for the treatment of fractures of proximal radius. Methods From August 2001 to April 2004, 24 patients suffering from fractures of proximal radius were treated with Ni-Ti shape memory alloy embracing fixator. Of 24 patients, there were 19 males and 5 females, aging from 16 to 48 years; there were 9 cases of wrestling injury, 5 cases of crush injury, 4 cases of traffic accident injury, 3 cases of direct violence impact injury and 3 cases of high falling injury. All patients were given operation according to fix method of the shape memory alloy embracing fixator. All cases were regularly followed up to observe the fracture healing and functional recovery. Results All cases were followed up postoperatively from 4 months to 21 months with an average of 10 months. No complication occurred during operation and after operation. Healing by first intention was achieved. X- ray showed that all cases achieved clinical union 8-12 weeks after operation. According to Anderson＇s criteria and the results were excellent in 18 cases, good in 5 cases, and fair in 1 case. The excellent and good rate was 95.83 %. Conclusion The internal fixation with shape memory alloy embracing fixator has as follows adventages; less trauma, esay-to-do, stable fixation, better tissue compatibility and less complication in treating fractures of proximal radius. This method can enhance the fracture healing and functional recovery. So it is a better method to treat fractures of proximal radius.
