Brief Summary

Surgical interventions for the removal of intervertebral disc fragments or to enlarge a narrow spine canal are commonly performed worldwide and are considered efficient. Concomitant low back pain is not uncommon among patients with lumbar nerve compression and neurological symptoms. When present, controversy persists in the literature regarding its ideal management. Although neurological symptoms improve after decompressive surgery, the presence of residual chronic low back pain may worsen satisfaction scores and cause functional disability. The hypothesis of the present study is that the presence of atrophy of the paraspinal and trunk muscles predicts chronic low back pain after lumbar neural decompression. If confirmed, this finding will aid in better planning of physical rehabilitation strategies for this group of patients, as well as a clearer prediction regarding surgical treatment outcomes for patients and health professionals.

Secondary Outcomes (7)

  • Radiological evaluation

    Baseline and 6 month after surgery

  • Change in Kinesiophobia

    Baseline, 3, 6, 12 and 24 months after surgery

  • Change in Psychosocial Risk Prognosis

    Baseline, 3, 6, 12 and 24 months after surgery

  • Change in Global Impression of Recovery

    Baseline, 3, 6, 12 and 24 months after surgery

  • Change in Mood Disorders in The setting of Medical Practice

    Baseline, 3, 6, 12 and 24 months after surgery

  • +2 more secondary outcomes

Other Outcomes (1)

  • Sociodemographic characteristics

Interventions

Patients with lumbar degenerative diseases and symptoms of nerve compression (radiculopathy or neurogenic claudication) who will undergo surgical treatment for neural decompression (discectomy, foraminotomy or laminectomy).

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The study will be conducted at the Israelita Albert Einstein Hospital (HIAE), a tertiary private philanthropic hospital located in the city of SĂ£o Paulo, Brazil. All participants will be from and treated at the institution's spine surgery outpatient clinics.

You may qualify if:

  • adults 18 years of age and older;
  • with symptoms of lumbosacral neural compression (radiculopathy or neurogenic lameness);
  • failed conservative treatment for at least 6 weeks;
  • undergoing surgery for neural decompression (discectomy and / or foraminotomy and / or hemilaminectomy);
  • with complete pre and postoperative medical records in all evaluations.

You may not qualify if:

  • need for lumbar arthrodesis;
  • deep infection requiring surgical cleaning;
  • patients submitted to joint facet rhizotomy;
  • active rheumatologic disease, including seronegative arthropathies.
