空心加压螺钉结合支撑钢板治疗Hoffa骨折

目的:评价空心加压螺钉结合支撑钢板内固定治疗Hoffa骨折的临床效果。方法:对9例Hoffa骨折患者采取切开复位、前后空心加压螺钉结合支撑钢板内固定治疗。按Letenneur 分型Ⅰ型5例,Ⅱ型2例,Ⅲ型2例。 2例合并髁上骨折,3例合并髁上、髁间骨折。并根据Hoffa 骨折术后功能恢复评估标准综合评估膝关节功能。结果:所有患者均获随访,时间3～24个月,术后切口均一期愈合,无早期并发症。术后内固定无松动、断裂,无骨折不愈合及股骨髁缺血性坏死发生。愈合时间8～12周。 Hoffa骨折术后功能恢复评估:优7例,良2例。结论:空心加压螺钉结合支撑钢板治疗Hoffa骨折内固定可靠,可早期进行功能锻炼,治疗效果满意。

Effect of cannulated screw combined with support plate in the treatment of Hoffa fracture

Objective:To investigate the clinical effects of cannulated screw combined with support plate in the treatment of Hoffa fracture. Methods:Nine patients with Hoffa fractures were treated with open reduction,anterior-to-posterior cannulated screw combined with support plate fixation. Type Ⅰ in 5 cases,type Ⅱ in 2 cases and type Ⅲ in 2 cases were observed in 5 males and 1 female according to Letenneur classification. Supracondylar fracture in 2 cases and supracondylar complicated with intercondylar fracture in 3 cases were found. The postoperative function of knee joint was evaluated according to the Letenneur knee function evaluation system. Results:All patients were followed up for 3 to 24 months. All incisions were primary healing without early complication. The interfixation loosing and rupture,fracture nonunion and avascular necrosis of femoral condyle were not found after operation. The time fracture healing was 8 to 12 weeks. The functional recovery of 7 cases and 2 cases were excellent and good according to Hoffa evaluation system, respectively. Conclusions:The theraputic effects of cannulated screw combined with support plate on Hoffa fracture are reliable and good,the patients can do early functional exercise.
