Abstract

Purpose: Genetic factors are considered important in the development of degenerative spine disease. The aim of this study was to determine the twin concordance rates for the common cervical spine diseases cervical disk herniation (CDH), cervical foraminal stenosis (CFS), and degenerative cervical myelopathy (DCM) requiring surgical treatment by studying monozygotic (MZ) and dizygotic (DZ) twin pairs.

Methods: Patients, aged 18-85 years, operated for CDH, CFS, or DCM between 1996 and 2022 were identified in the national Swedish spine register (5962 CDH, 3801 CFS, and 3131 DCM) and matched with the Swedish twin registry to identify MZ and DZ twins. Concordance rates were calculated.

Results: There were 64 twin pairs where one or both twins had surgical treatment for CDH. The corresponding numbers for surgically treated CFS and DCM were 37 twin pairs and 44 twin pairs respectively. For twins with CDH we found one concordant MZ pair and no concordant DZ pair (MZ probandwise concordance rate 0.12 [95% CI 0-0.33]). For twins with CFS we found one concordant MZ pair and no concordant DZ pair (MZ probandwise concordance rate 0.14 [95% CI 0-0.38]). In DCM patients we found no concordant twin pair.

Conclusions: In this national observational study, including 145 twin pairs, the concordance rates were low for surgically treated CDH, CFS, and DCM conditions. Our findings suggest that not only genetic factors, but also environmental factors and personal preferences are important whether a patient goes to surgery for this type of condition.

期刊介绍： "European Spine Journal" is a publication founded in response to the increasing trend toward specialization in spinal surgery and spinal pathology in general. The Journal is devoted to all spine related disciplines, including functional and surgical anatomy of the spine, biomechanics and pathophysiology, diagnostic procedures, and neurology, surgery and outcomes. The aim of "European Spine Journal" is to support the further development of highly innovative spine treatments including but not restricted to surgery and to provide an integrated and balanced view of diagnostic, research and treatment procedures as well as outcomes that will enhance effective collaboration among specialists worldwide. The “European Spine Journal” also participates in education by means of videos, interactive meetings and the endorsement of educative efforts.
