Objective:To further define the parameters for nonsurgical management of thoracolumbar junction burst fractures.Summary of Background Data.Many texts list involvement of the posterior column as an indication for surgery and state that casting or bracing is mandatory.This has not been the authors experience.Methods.Thirty eight patients with nonpathologic,single level burst fractures of T 11 、 12 、L 1 or L 2,and with posterior element fractures were studied retrospectively.The selection criteria required that patient be neurological intact,that the pedicles and facet joints not be fractured or dislocated,and that the angle of kyphosis be less than 35°.The extent of retropulsion,loss of vertebral height,and presence of lamina or process fractures were not criteria.No attempt was made to reduce the fracture.Patients were allowed immediate ambulation as tolerated.Jewett braces were used in nine patients,but no bracing was used in the remainder.Results.There were 22 males,16 females.Median age 37 years(range,16~65).Fracture involved both endplates in 16 patients(12 crush cleavage type),the superior endplate in 21,and the inferior endplate in 1. The hospital stay was from 2 to 18 days (median,8 days).Follow up averaged 4 1 years(range,2 1~6 3).All patients remained neurological intact.Eight patients had no pain,24 had minimal pain,4 had moderate pain,and 2 had moderate to sever pain.Twentynine of 38 patients(76%)were able to work at the same level.The initial kyphosis angle averaged 20°(range 10°~35°).At follow up it averaged 24°(range 12°~38°).The maximum increase was 6°.Some degree of retropulsed fragment resumption was noted in 35 cases.Complications were limited to transient urinary retention.There were no thromboembolisms,decubitus ulcers,or pulmonary complications.Conclusion:Despite the use of less restrictive criteria,no brace,and early activity as tolerated,the results are similar to those obtained with more restrictive protocols.The presence of vertical lamina fracture,spinous process fracture,and transverse process fracture are not contraindications.Activity restriction and bracing may be important for pain control but probably does not change the long term result.
