NCT02936765

Brief Summary

This is an investigator-initiated study. The primary goal is to evaluate the efficacy of two different cervical disc devices (prosthesis vs rigid spacer) with respect to postoperative change in neck disability index. The evaluation will include clinical and radiological parameters.

Outcome Measures

Primary Outcomes (1)

  • Change in Neck disability index compared to baseline

    6 weeks, 3, 6, 12 and 24 months postoperative

Secondary Outcomes (21)

  • Change in visual analogue scale for pain in the neck and peripheral pain compared to baseline

    6 weeks, 3, 6, 12 and 24 months postoperative

  • Change in EuroQOL (EQ-5D) compared to baseline

    6 weeks, 3, 6, 12 and 24 months postoperative

  • Change in Core Outcome Measure Index (COMI) compared to baseline

    6 weeks, 3, 6, 12 and 24 months postoperative

  • Change in flexion and extension radiographs compared to baseline (angle difference [deg]).

    6 weeks, 3, 6 and 12 months postoperative

Study Arms (2)

Elastic spine pad

EXPERIMENTAL

Patients, who receive Elastic Spine Pad (TM) as cervical disc prosthesis after ventral discectomy.

Device: Anterior cervical discectomy with prosthetic disc replacement / ESP.

Squale

ACTIVE COMPARATOR

Patients, who receive Squale (TM) as cervical disc prosthesis after ventral discectomy.

Device: Anterior cervical discectomy with prosthetic disc replacement / Squale.

Interventions

Anterior cervical discectomy, with the use of the ESP prosthesis (Manufacturer: FH orthopedics, Mulhouse, France) for the disc replacement.

Elastic spine pad

Anterior cervical discectomy, with the use of the Squale spacer (Manufacturer: OSD, Avignon, France) for the disc replacement.

Eligibility Criteria

Age18 Years - 50 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • Indication for monosegmental anterior cervical discectomy with implantation of a disc prosthesis

You may not qualify if:

  • Radiologic signs of extensive bone degeneration in the affected segment
  • Necessity of implantation of a device smaller in height than 5 mm (as predicted with teh use of the Vertaplan (TM) software
  • Transversal spine cord lesion
  • Cervical myelopathy
  • Preceding surgery on the cervical spine
  • Traumatic lesions of the cervical spine
  • Radiographic instability in the affected segment: flexion / extension: shift sagittal plane\> 3.5 mm or 20% and rotation in the sagittal plane \> 20 °, OR in static X-ray examinations: shift in the sagittal plane 3.5 mm or 20% of the vertebral body width and relative sagittal plane angulation \> 11º
  • signs of instability (Olisthesis) in another segment of the cervical spine
  • Active systemic infection
  • diseases of the rheumatic type and all autoimmune diseases
  • bone metabolic diseases (for example, Paget's disease)
  • skeletal metastases
  • infections in the cervical spine
  • Neurological seizure disorders or other serious neurological disease with risk of falls
  • Severe heart failure (NYHA III-IV)
  • +9 more criteria
