Introduction: Customized, patient-specific interbody cages have been used in the treatment of spinal neoplasia, degenerative disease, infection, congenital anomalies, and trauma. However, to date, their use has been limited to a single spinal level, and the utility of customized spinal implants in multiple spinal levels remains unclear. In addition, limited studies exist that compare outcomes following fusion and decompression surgery using customized implants to traditional, standard implants.
Case report: We present two cases. Case 1 consists of a multilevel deformity surgery from L3-S1 ALIF and T10-Pelvis PSF in a patient with a congenital scoliosis (CS) using customized implants on multiple spinal levels. We compare Case 1 to Case 2, in which a patient underwent a lumbar decompression and fusion for CS using standard titanium implants. While the patient in Case 1 reported improved back pain and independent ambulation at 1-year post-operative and required no revision surgery, the patient in Case 2 required revision surgery 2 years post-operative due to pseudoarthrosis.
Conclusion: CS with right wedge hemivertebrae may be treated with customized implants on multiple spinal levels, and customized implants may provide benefit standard implants.
