Bold螺钉治疗腕舟骨骨折

Treatment of carpal scaphoid fracture by internal fixation with Bold screw

目的探讨Bold螺钉内固定治疗腕舟骨骨折的疗效。方法用Bold螺钉内固定治疗腕舟骨骨折35例,其中新鲜不稳定性腕舟骨骨折21例,腕舟骨骨折不愈合14例。结果35例均获随访,21例新鲜不稳定性腕舟骨骨折术后平均随访(12·1±5·2)个月;腕舟骨骨折不愈合14例术后平均随访(13·6±2·7)个月。骨折全部骨性愈合。采用改良Mayo法对腕关节功能进行评估:优27例,良5例,尚可3例。结论Bold螺钉治疗腕舟骨骨折对骨折端有加压作用,具有固定稳固、可经关节面置入、无需取出等优点。

Objective To investigate treatment outcome of fracture of the scaphoid by internal fixation using Bold screw. Methods In the 35 patients with fracture of the carpal scaphoid, unstable fracture（21 cases ） and nonunion fracture（ 14 cases） of the scaphoid were treated by internal fixation with Bold screw. Results 35 patients were followed up for 13 -20 months. 21 cases with unstable scaphoid fractures were followed up for a mean period of 12. 1 ± 5.2 months; 14 cases with scaphoid nonunion was followed up for an average period of 13.6 ± 2. 7 months. All cases were healed. Conclusions Internal fixation with the Bold screw for scaphoid fracture has several advantages ： it can produce compression at the fracture site, provide rigid fixation for fracture, be introduced through the articular surface of the joint and the removal of the implant is not necessary.
