Experimental: combined surgery
combined surgery for enrolled patients with CPT(Congenital Pseudarthrosis of Tibia): sleeve resection of the pathological soft tissues, intramedullary rod fixation, packaged lilac bone autograft,and llizarov external fixation device installation.
Device: llizarov external fixation device
llizarov external fixation device was applied to fix the tibia.
Other Name: llizarov fixator
Device: intramedullary rod fixation
retrograde intramedullary rod was applied to stabilize the tibia.
Other Name: intramedullary rodding
combined surgery for enrolled patients with CPT: sleeve resection of the pathological soft tissues, retrograde intramedullary rodding, packaged lilac bone autograft,and llizarov external fixation device installation.
Other Name: combined surgery
- whether the tibial has obtained union. [ Time Frame: 6 months post-operation ]Ohnishi criterion: Degree of union was evaluated by the findings on radiographs and classified into three grades( Ohnishi criterion): union, delayed union, and nonunion. Radiographic union was defined as possessing continuity of bone density between the fragments without obvious radiolucent zone between them and possessing cortex-bridging fragments with sufficient thickness and radiodensity on both anteroposterior and lateral radiographs. Delayed union was defined as a process of healing that was slow but was progressing. Nonunion was defined by the healing process that had completely ceased.
- clinical outcome measurement(Johnston clinical evaluation criterion) [ Time Frame: 3,6,9,12,18,24 months post-operation ]
Johnston clinical evaluation criterion of Congenital Pseudarthrosis of Tibia (CPT): The outcome was classified as grade
1 when there was unequivocal union with full weight-bearing function and maintenance of alignment requiring no additional surgical treatment; grade 2 when there was equivocal union with useful function, with the limb protected by a brace, and/or valgus or sagittal bowing for which additional surgery was required or anticipated; and grade 3 when there was persistent nonunion or refracture, requiring full-time external support for pain and/or instability.
- Refracture of tibia [ Time Frame: 0.5 , 1,2,3,4,5,6,7,8,9,10 years post-operation ]The continuity of tibia cortex was disappeared in X ray.
- Residual Deformity-proximal tibia angulation(range,0°-90°) [ Time Frame: pre-operation and 0.5 , 1,2,3,4,5,6,7,8,9,10 years post-operation ]measurement of the angulation of proximal tibia in anterior and posterior (AP )and lateral X ray
- Residual Deformity-Limb length discrepancy [ Time Frame: pre-operation and 0.5 , 1,2,3,4,5,6,7,8,9,10 years post-operation ]measurement of the length difference of both tibia in AP and lateral X ray
- Residual Deformity-ankle valgus angulation(range,0°-90°) [ Time Frame: pre-operation and 0.5 , 1,2,3,4,5,6,7,8,9,10 years post-operation ]measurement of the angulation between the distal tibia and ankle joint.
