带骨骺腓骨近段移植重建小儿尺骨远端骨骺2例

Reconstruction of distal ulna osteoepiphysis after osteochondroma resection in children proximal fibular graft including osteoepiphysis 2 cases report

目的探讨吻合血管带骨骺腓骨近段移植重建小儿骨软骨瘤切除后尺骨远端骨骺、矫正腕关节畸形的临床效果。方法采用吻合血管带骨骺腓骨近段移植重建2例小儿骨软骨瘤切除后尺骨远端骨骺、矫正其腕关节畸形，并评价其临床效果。结果2例患儿的腕关节尺偏畸形得到矫正，术后2个月所有腓骨移植近段与受区骨端愈合良好．分别随访1年和6年，重建的尺骨远端与健侧肢体几乎同步生长，腕关节形态功能满意。结论吻合血管带骨骺腓骨近段移植能有效重建小儿骨软骨瘤切除后尺骨远端骨骺并长期矫正其腕关节尺偏畸形。

Objective To report the clinical effect of correction wrist deformity and reconstruction of distal ulna osteoepiphysis after osteochondroma resection with free vascularized proximal fibular graft including osteoepiphysis in children. Methods Adopt free vascularized fibular grafts with fibular head including epiphysis as substitutes for correction of wrist deformity and reconstruction of distal ulna osteoepiphysis after osteochondroma resection in 2 patients, and investigate the clinical effect. Results Among the 2 cases, the outcomes in correction of wrist deformity was satisfactory. The bone union between fibular grafts and hosts was found in 2 months postoperatively. Within 1-year and 6-years follow-up respectively, the reconstructed distal ulna and contralateral limbs were almost growing simultaneously, morphology and function of the wrists were also approving. Conclusion Free vascularized fibular graft with fibular head including osteoepiphysis can effectively correct the ulnar drift deformity and reconstruct the distal ulna osteoepiphysis after osteochondroma resection in children.
