The complications included 2 cases of intra operative laminar and/ or pedicle fractures and 2 cases of dislodgement of the hooks and 1 case of pseudoarthrosis. 并发症包括椎板、椎弓骨折2例、脱钩2例、假关节1例。
Estrogen Receptor in Congenital Pseudoarthrosis of Tibia: An Immunohistochemical Study 先天性胫骨假关节雌激素受体的免疫组织化学研究
Methods: the Ilizarov technique was used in 12 patients ( 14 legs) with short leg, 2 with congenital tibia pseudoarthrosis, 1 with bone defect following osteomyelitis and 9 with congenital clubfoot. 方法:应用Ilizarov技术治疗下肢短缩12例(14个肢体),先天性胫骨假关节2例,骨髓炎骨缺损1例,矫治先天性马蹄内翻足9例。
Conclusion The main reason of the failed operation included dificient decompression, the internal fixation loosen and broken, grafting bone absorbed and pseudoarthrosis formation. 结论手术失败原因包括:减压不够彻底、植骨块吸收、假关节形成,内固定松动、断裂造成复位丢失和滑脱复发。
Patients developed nonunion, 2 of 3 failures were firstly recognized in the operation of removing the internal devices, the remained one was found signs of pseudoarthrosis on X ray films taken 8 months after instrumentation and identified in the secondary operation. 3例失败,其中2例二次取内固定术中才被发现,第3例术后8个月X线片有假关节形成表现,再次术中也证实有假关节形成。
Results For group A, an average of 73.2% correction rate was achieved, and average 10% loss of correction and 3% of pseudoarthrosis was recorded at 2 year follow-up. A组患者术后Cobb角平均矫形率为73.2%。随访2年时矫形丢失率为10%,假关节发生率为3%。
And it has also achieved definite curative effects for compressed limb lengthening to congenital tibial pseudoarthrosis. 对先天性胫骨假关节进行加压时延长肢体取得了确切的疗效。
Combined Bone Lengthening and Compressing in the Treatment of Congenital Pseudoarthrosis of Tibia 一次性加压延长治疗先天性胫骨假关节
Results Among 63 cases, the long-term complications included persistent low back pain in 4 cases ( 6.34%), limb pain with numbness in 3 cases ( 4.76%), pseudoarthrosis formation in 2 cases ( 3.33%) and broken nails 2 cases ( 3.33%). 结果63例患者中,术后并发症主要有:腰痛及下肢痛4例,占6.34%,下肢痛伴麻木3例,占4.76%,假关节形成2例,占3.33%,断钉2例,占3.33%。
Nonunion and pseudoarthrosis formation of fracture site; 骨折后骨不连和假关节形成;
Cases with pseudoarthrosis formation received operation. 2例因骨折端假关节形成改为手术治疗。
Furthermore, the spinal arthrodesis will produce many complications, such as iliac donor site morbidity, failure of the fusion and pseudoarthrosis. 此外,脊柱融合术还会带来髂骨等供骨区疼痛、植骨块不融合、假关节形成以及内固定断裂等并发症。
