Detailed Description
The study aims to evaluate the clinical result of Combined Surgery in Management of Congenital Pseudarthrosis. The combined surgery includes sleeve resection of the pathological soft tissues, retrograde intramedullary rodding, packaged lilac bone autograft,and appliance of llizarov external fixation device. Bone uion rate,average time of healing, Healing index, ankle valgus, limb length discrepancy, tibia axis alignment are recorded and evaluated.

Outcome Measures
Primary Outcome Measures
- whether the tibial has obtained union. [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.
Secondary Outcome Measures
- clinical outcome measurement(Johnston clinical evaluation criterion) [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 [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.
Other Outcome Measures
- Residual Deformity-proximal tibia angulation(range,0°-90°) [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 [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°) [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.
