直型外固定支架牵张治疗青壮年桡骨远端粉碎性塌陷性骨折46例

46 cases of straight distraction external fixation for comminuted and compressed distal radius fractures in young adults.

目的探索青壮年桡骨远端粉碎性塌陷性骨折的治疗方法。方法通过直型外固定支架牵张治疗青壮年桡骨远端粉碎性塌陷性骨折46例。结果经6~28个月(平均11.6个月)随访,未发现神经血管损伤,无切口感染,无骨折畸形愈合病例,手握力恢复,骨折全部愈合;1例开放性骨折,腕关节功能恢复欠佳。根据Dienst功能评定标准:优31例,良12例,可2例,差1例,优良率93.5%。结论直型外固定支架牵张复位固定,符合骨生长的生物力学环境,骨愈合快,可早期有效地进行手指及腕关节功能锻炼,是治疗桡骨远端粉碎性塌陷性骨折的理想方法,可在临床推广应用。

Objective To explore the treatment for comminuted and compressed fractures of distal radius in young adults.Methods Treat 46 young adults with straight distraction external fixation for comminuted and compressed distal radius fractures. Remove the external fixation in 4 to 5 weeks, then proceed the functional exercise. Results After 6 to 28months(mean 11.6 months) follow-up, no nerve and blood vessel damage and no other complications occured. The grip strength were recovery and all fractures healed without wounds and pin tract infection. No nonunion cases. One case got a open fracture whose wrist function recovered poor. According to the function assessment from Diensts: 31 excellent cases, 12 good cases, 2 fair cases and poor in 1 case, the excellent and good rate is 93.5%. Conclusion Straight external fixator distraction is fit for the biomechanical environment, good for bone healing and can get a good joint function which is an ideal method for comminuted and compressed distal radius fracture.
