Researchers found good sagittal range of motion after patients underwent cervical fusion surgery for revisions or spinal deformity.
“Patients frequently express concern over the likely loss of range of motion of the neck postoperatively,” the authors wrote in the study. “A substantial degree of saggital range of motion can be maintained after extensive surgical fusion of the cervical spine.”
The researchers collected data from medical records of 30 patients who underwent extensive cervical fusion between 1996 and 2008. The researchers defined an extensive cervical fusion as “an upper instrumented vertebra proximal to C3 and lower instrumented vertebra distal to C7,” according to the study. The patients were an average age of 58.3 years old and patients were followed for an average of 34.5 months.
The levels surgeons operated on included occiput to T1 (one patient), occiput to T4 (one patient), occiput to T6 (one patient), C1 to T1 (one patient), C1 to T2 (one patient), C2 to T1 (nine patients), C2 to T2 (eight patients), C2 to T3 (six patients) and C2 to T4 (two patients). Indications for surgery included 27 revisions, one chin-on-chest deformity, one cervical scoliosis patient and one multilevel cervical myelopathy.
The overall cervical range of motion was 34.1°±14.7°, the mean occipitocervical angle range of motion was 29.5°±11° and the mean cervicosternal angle range of motion was 7.5°±5°.
