Anterior cervical discectomy with fusion (ACDF) and cervical corpectomies are commonly performed procedures in the neurosurgery and orthopedic units across the world. The size of the graft or prosthesis used is variable on individual basis. Also, geographical variations seem to play one of the vital roles in determining the size of the cervical vertebral body and intervertebral disk dimensions.
Objective
To study dimension of C3 to C7 vertebral body and C2/3 to C7/T1 intervertebral disk.
Inclusion criteria
Nepalese nationality aged between 18 to 60 year old and those with normal cervical spine Magnetic resonance imaging.
Exclusion criteria
Traumatic cervical spine and any pathological lesion, such as infection/tumor, destructing the normal morphology of cervical vertebra.
Study design
Cross-sectional study.
Sample size
Fifty-two cases.
Sampling technique
Nonprobability consecutive sampling.
Duration
Retrospective 1 year.
Results and conclusion
There were a total of 52 patients, 33 female and 19 male. With increasing age of C5 to C7, anterior-posterior (AP) diameter increases significantly. No significant association in different gender was noted. However, vertical height was smaller and AP diameter was in-between the study done at Israel and the US. Thus, there seems to exist geographical variation in the dimension of the cervical spine and may possess a greater clinical impact. The dimensions of the cervical spine may need to be considered while designing the prosthesis used in ACDF for Nepalese population.
