Brief Summary

Degeneration, iatrogenic-/idiopathic causes and fractures can lead to kypho- scoliotic deformities potentially resulting in pain and loss of function. The surgical strategies rely on surgeon preferences and type of deformity as well as clinical symptoms. The complication rate of surgical treatment is high. The aim of this study is to elucidate the indications for surgical treatment of kyphoscoliosis and evaluate the effectiveness of surgical and non-surgical outcome clinically and radiologically. The primary outcome for the PROMs and x-ray is at 12 months, but the investigators will also follow the patients with the PROMs and x-rays after 2,5 and 10 years.

Outcome Measures

Primary Outcomes (1)

  • Oswestry Disability Index (ODI)

    One of the principal condition-specific outcome measures for spinal disorders. Scale from 0-100%, high scores equales increasing disability; 0-20% minimal disability, 20-40% moderat disability, 40-60% severe disability, 60-80% crippled, 80-100% bed bound or exaggerating their symptoms.

    12 months

Secondary Outcomes (5)

  • Euroqol (EQ-5D)

    12 months

  • Numeric rating scale (NRS)

    12 months

  • Scoliosis research society (SRS22)

    12 months

  • Lumbar stiffness disability index(LSDI)

    12 months

  • Urination- and sexual function (USF)

    12 months

Study Arms (2)

Non-surgical

A non-surgical group for comparison, they will conduct a training program tailored for the kyphoscoliotic patients. The inclusion criteria is the same as for the surgical group.

Other: Non-surgical

Surgical

Patients operated with correction of kyphotic- or scoliotic deformity.

Procedure: Surgical

Interventions

We have constructed a training program with help from physiotherapists from Rikshospitalet in Oslo, tailored for kyphotic- and scoliotic patients.

Non-surgical
SurgicalPROCEDURE

Surgery for correction of kyphotic- or scoliotic deformity.

Eligibility Criteria

Age25 Years+
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients from the age of 25 and older are included in the study, if they have a deformed spine that fulfil the inclusin criteria and non of the exclusion criteria. The patients are selected from the outpatient clinic in the including university hospitals (Area of Kyoto in Japan, Örebro in Sweden and the vestcoast as well as the souteast area of Norway).

You may qualify if:

  • Out of coronar or sagittal balance: A correction of 20 degrees or more is possible due to the degree of degeneration.
  • \>25 years
  • \>30% ODI score

You may not qualify if:

  • Do not want to participate and not able to answer PROMs
  • Acute fractures (not healed fractures)
  • Disc prosthesis
  • Neuromuscular cause of deformity (the investigators include Parkinson patients)
  • Activ infection or malignancy
  • Ideopatic scoliosis with typical add on (the investigators include those that have \<20 degrees of scoliosis at Risser 5 and/or the scoliosis increase in age due to degeneration). If unknown, the patient will be included as a de novo scoliosis.
