NCT06113263

Brief Summary

This is a prospective observational register-based cohort study with 2 years follow-up with data from the national Swedish Spine Register (Swespine). The aim is to study the differences between anterior and posterior decompression surgery on neck-related disability, headache, and neck- and arm pain in individuals with cervical radiculopathy and headache. Secondary, to study predictive factors for an improvement in neck-related disability, headache and neck- and arm pain after decompression srurgery. All individuals underwent either anterior or posterior decompression surgery and were operated between 2014-2021. Patient-reported data was collected preoperatively (baseline), and at 1- and 2-year follow-ups and surgeon-reported data regarding the operation were collected directly after the operation. Primary outcome is self-reported neck-related disability measured with Neck Disability Index and secondary outcomes are headache, measured with an item about headache of Neck Disability Index, and neck- and arm pain, measured with a 0 to 10-point numeric rating scale.

Outcome Measures

Primary Outcomes (1)

  • Neck Disability Index

    To measure neck-specific disability; 0-100 % (0 % = no disability)

    Preoperatively to 24 months follow-up

Secondary Outcomes (11)

  • Headache measured with an item of Neck Disability Index

    Preoperatively to 24 months follow-up

  • Numeric rating scale

    Preoperatively to 24 months follow-up

  • Bakground variables

    Preoperatively

  • Duration of neck pain

    Preoperatively

  • Duration of arm pain

    Preoperatively

  • +6 more secondary outcomes

Study Arms (2)

Anterior cervical decompression surgery

Individuals underwent anterior cervical decompression surgery due to cervical radiculopathy

Procedure: Anterior cervical decompression surgery

Posterior cervical decompression surgery

Individuals underwent posterior cervical decompression surgery due to cervical radiculopathy

Procedure: Posterior cervical foraminotomy with or without laminectomy

Interventions

The aim of the surgery is to reduce the compression of the affected nerve. With anterior cervical decompression surgery this is achieved by removing the disc and osteophytes.

Anterior cervical decompression surgery

The aim of the surgery is to reduce the compression of the affected nerve. With posterior cervical decompression surgery more space is created for the nerve by widening the foramina where the nerve exits

Posterior cervical decompression surgery
