摘要:

文题释义:
Pilon骨折:为累及胫骨远端负重关节面的关节内骨折,干骺端常有不同程度的压缩、粉碎,且伴有不同程度的软组织损伤和关节软骨原发性损伤。
Meta钢板:美国强生公司设计制造的用于治疗胫骨远端骨折的钢板,其远端呈三角形或菱形,特点是较同类型其他钢板薄,对局部软组织的张力影响小。


背景:Pilon骨折通常损伤较重,干骺端有不同程度的压缩、粉碎,且伴有不同程度的软组织损伤和关节软骨原发性损伤,治疗困难,预后相对较差。

目的:探讨Meta钢板联合微型钢板内固定治疗干骺端前方粉碎的冠状面Pilon骨折的效果。

方法:2013年1月至2017年6月西南医科大学附属医院骨与关节外科收治闭合性干骺端前方粉碎的冠状面Pilon骨折患者17例,其中男7例,女10例;年龄24-62岁,平均41.3岁。所有患者对治疗方案均知情同意,且得到医院伦理委员会批准。术前均经CT三维重建证实主要骨折线呈冠状面走形,胫骨远端干骺端前方多发骨折碎块且有明显移位,根据Rüedi-Allgöwer分型,Ⅱ型3例,Ⅲ型14例。关节面骨折碎块以横置掌指微型钢板螺钉固定,冠状面胫骨远端骨折以前方Meta钢板固定。采用美国足踝外科协会踝-后足评分评价术后功能。

结果与结论:①17例患者获得12-28个月随访。所有切口均Ⅰ期愈合,无切口感染、皮肤坏死、内固定失败、神经血管损伤等并发症发生;仅1例患者术后出现切口部分边缘发红,经消肿换药等处理后好转愈合;②骨折均在3-6个月内愈合,无延迟愈合及不愈合发生;③末次随访时美国足踝外科协会踝-后足评分:优10例,良5例,可2例,优良率为88%;④提示应用横置微型钢板螺钉固定可有效支撑固定关节面骨折碎块,联合胫骨远端前方Meta钢板治疗干骺端前方粉碎的冠状面Pilon骨折可取得良好的修复效果,加强生物力学稳定性。

Abstract:

BACKGROUND: Pilon fractures usually happened during severe injury, associated with compression and comminution of metaphysis and soft tissue injury and primary articular cartilage damage in varying degrees.The treatment is difficult and the prognosis is relatively poor.

OBJECTIVE: To explore the clinical effect of application of meta-plate and mini-plate internal fixation for the treatment of anterior comminuted coronal plane Pilon fractures. 

METHODS: From January 2013 to June 2017, 17 patients of closed anterior comminuted coronal plane Pilon fractures were admitted in Department of Bone and Joint Surgery, Affiliated Hospital of Southwest Medical University. There were 7 males and 10 females, aged from 24 to 62 years, with an average age of 41.3 years. All patients signed the informed consent. This study was approved by the Hospital Ethics Committee. Preoperative CT scans and three-dimensional reconstruction confirmed that the main fracture line was in coronal plane and multiple fragments of distal tibial metaphysis were displaced obviously. According to Rüedi-Allgöwer classification, there were 3 cases of type II and 14 cases of type III. Fracture fragments of articular surface were fixed with transverse metacarpophalangeal mini-plate and screws, and the distal tibial coronal fractures were fixed with anterior meta-plate. The ankle and hind foot score of the American Orthopaedic Foot and Ankle Society was used to evaluate the function after surgery.

RESULTS AND CONCLUSION: (1) The 17 patients were followed up for 12 to 28 months. All incisions healed in the first stage without complications such as wound infection, skin necrosis, failure of internal fixation and neurovascular injury. Only one patient had redness on the edge of the incision after operation and healed after swelling reduction and dressing change. (2) Fractures healed within 3 to 6 months without delayed union or nonunion. (3) At the last follow-up, the American Orthopaedic Foot and Ankle Society ankle and hind foot score was excellent in 10 cases, good in 5 cases, and average in 2 cases. The excellent and good rate was 88%. (4) The application of transverse mini-plate and screws fixation can effectively support and fix the fracture fragments of articular surface. Combined with anterior meta-plate of distal tibia for the treatment of anterior comminuted coronal plane Pilon fractures can achieve good therapeutic effect, and strengthen biomechanical stability.
