Clinical effect the modified Halo-pelvic traction on patients with severe spinal deformity accompanied by respiratory disorder
Objective To explore the clinical effect of one-stage modified Halo-pelvic traction combined with two-stage surgery on severe spinal deformity accompanied by respiratory disorder.Methods From January 2019 to January 2022,a total of 120 patients with severe spinal deformity accompanied by respiratory disorder were enrolled at Beijing Dawang Lu Emergency Hospital.All patients underwent modified Halo-pelvic traction followed by surgical correction.The changes in imaging and respiratory function indicators were compared at pre-traction,post-traction,post-operation and the last follow-up.Results At pre-traction,the Cobb angle at the main curvature,distance between the C7 plumb line and the central sacral vertical line(C7PL-CSVL),apical vertebral translation(AVT),T1 tilt angle,radiographic shoulder height,sagittal vertical axis(SVA),and thoracic kyphosis(TK)were(119.17±15.39)°,(33.33±7.2)mm,(103.55±16.56)mm,(20.13±5.94)°,(26.78±6.32)mm,(38.29±5.54)mm,and(87.66±11.63)°,respectively.They were significantly higher than those at post-traction([74.62±15.15]°,[13.23±4.27]mm,[57.70±17.56]mm,[9.29±1.73]°,[10.18±2.00]mm,[14.41±3.24]mm,and[52.96±12.11]°,respectively),post-operation([60.78±14.40]°,[12.42±3.58]mm,[44.31±13.77]mm,[8.89°±2.66]°,[9.38±2.39]mm,[17.11±3.24]mm,and[51.28±11.20]°,respectively)and last follow-up([64.21±14.86]°,[12.69±3.26]mm,[45.17±11.65]mm,[6.51±1.77]°,[9.53±2.36]mm,[17.50±3.07]mm,and[51.82±12.20]°,respectively)(P<0.01).At pre-traction,the forced vital capacity(FVC),FVC%,forced expiratory volume(FEV1)and FEV1%were(1.13±0.19)L,(31.61±4.64)%,(1.08±0.22)L,and(29.68±11.56)%,respectively.They were significantly lower than those at post-traction([1.36±0.28]L,[36.19±4.95]%,[1.17±0.19]L,and[33.45±5.97]%,respectively),post-operation([1.49±0.28]L,[38.08±7.46]%,[1.26±0.22]L,and[35.91±7.81]%,respectively)and the last follow-up([1.53±0.26]L,[38.61±6.91]%,[1.28±0.24]L,and[36.88±7.85]%)(P<0.01).Conclusion Modified Halo-pelvic traction can effectively correct spinal deformity of patients with severe spinal deformity accompanied by respiratory disorder,and improve the respiratory function,which is a safe and effective adjuvant treatment measure.
