![• Patients typically receive traction for 3–8 weeks
at 30%– 50% of their BW
• Traction weight was based on BW (kg) and
etiology, represented as
%BW: ([traction weight/BW] × 100%)
• One to two pounds (0.45–0.91 kg) of weight
was added daily until goal %BW was achieved
• The mean absolute correction for kyphosis
deformity was 35° ± 16.3° (range 18°–68°)

- 35. Predictors of Success •Most dominant factor associated with traction efficacy, seen from the evaluation of series lateral cervical X-Ray, was FL, indicating cervical traction failure 3.8 times higher in the presence of FL, than patients not present with FL • With the presence of a FL, it is estimated that traction failure increased to 26% and mortality to 7% and unilateral FL has a trend of higher traction failure compared with bilateral FL • In the treatment of subaxial cervical injuries >24 hours, there need to be informed consent to traction failure • Dahlan, Rully & Ompusunggu, Sevline & Yudoyono, Farid & Malau, Lukas & Ramani, Premanand.
