掌侧切开双螺钉顺行固定治疗Herbert B2型腕舟骨骨折的疗效观察

目的：探讨掌侧切开顺行双螺钉固定治疗Herbert B2型腕舟骨骨折的临床及功能疗效。方法：自2005年12月至2010年6月，应用掌侧切开双螺钉顺行固定技术治疗18例Herbert B2型腕舟骨骨折患者，男14例，女4例；年龄21～52岁，平均33.11岁。术后通过X线检查评价其骨折愈合情况，采用改良Mayo腕关节功能评分评价腕关节功能。结果：18例患者获随访，平均随访时间（25.06±4.00）个月，骨折愈合时间（3.55±0.65）个月。18例患者术后4个月腕关节疼痛情况、活动范围、握力均优于术前（P<0.05）.改良Mayo腕关节功能评分由术前42.78±7.32改善至术后4个月的93.89±5.83，术后4个月各项评分及总分均明显优于术前（P<0.05），优9例，良9例。结论：应用掌侧切开顺行固定技术治疗Herbert B2型腕舟骨骨折，其临床及功能疗效可靠。

Treatment of Herbert B2-type scaphoid fracture with double screws prograde internal fixation through volar approach

Objective: To explore the clinical and function efficacy of the treatment of Herbert B2-type scaphoid fracture through volar approach with double screws prograde internal fixation. Methods: From December 2005 to June 2010,18 patients with Herbert B2-type scaphoid fracture were treated with double screws prograde internal fixation through volar approach,including 14 males and 4 females with an average age of 33.11 years(ranged from 21 to 52 years). The fracture healing situation was evaluated by X-ray examination. Functional outcome was assessed by using Modified Mayo wrist score. Results: All patients were followed up with a mean time of(25.06±4.00) months. The bone healing time was(3.55±0.65) months. The pain,passive range of motion,grip of wrist were improved at 4 months after operation(P<0.05). The Mayo wrist score were improved from preoperative 42.78±7.32 at 4 months after operation(93.89±5.83)(P<0.05),the results were excellent in 9 cases and good in 9 cases. Conclusion: Volar approach with double screws prograde internal fixation is an efficacy and safety surgical technique for Herbert B2-type scaphoid fracture.
