目的探讨尺神经沟置针与桡侧克氏针交叉固定治疗儿童GartlandⅢ型肱骨髁上骨折的可行性及疗效。方法1998～2004年采用该方法治疗儿童GartlandⅢ型肱骨髁上骨折46例,术后测量BA角(Baumann角),于1年时按JOA肘关节功能评价法行功能评价。结果术后BA角(72.5±3.5)°,随访1年总优良率98%,无肘内翻畸形,无继发尺神经损伤。结论该方法可有效防止骨折远端继发尺偏移位,维持BA角,防止其增大,有效地避免了肘内翻的发生。尺神经前置可有效地防止继发尺神经损伤。
Objective To investigate the feasibility and efficacy of supraclavicular fractures of Gartland Ⅲ type in humerus of children with ulnar nerve graft and radial Kirschner wire cross fixation. Methods From 1998 to 2004, 46 children with Gartland type Ⅲ supracondylar humerus fractures were treated by this method. BA angle (Baumann angle) was measured after operation. The functional evaluation of JOA elbow joint function was performed at 1 year. Results Postoperative BA angle (72.5 ± 3.5) °, follow-up 1 year total excellent rate of 98%, no elbow varus deformity, no secondary ulnar nerve injury. Conclusion This method can effectively prevent the distal fracture of the distal ulnar shift, maintain the BA angle, to prevent its increase, effectively avoiding the occurrence of cubitus varus. Anterior ulnar nerve can effectively prevent secondary ulnar nerve injury.
