Brief Summary:

This study will be conducted at Research Institute of Traumatology and Orthopedics (NRITO) n.a. Ya.L.Tsivyan, Novosibirsk, Russia.

The current study is prospective pilot clinical study to demonstrate the possibility and effectiveness of performing modified technique of MIS TLIF, supplemented by segmental vertebrotomy, to correct segmental deformity of lumbar spine.

It is expected to enroll 10 patients aged 18-70 with segmental deformity of lumbar spine, caused by degenerative spondylolisthesis and/or degenerative stenosis.

Arm Intervention/treatment
Treatment Arm Procedure: Minimally invasive one-level lumbar deformity correction
The study treatment represents modified technique of MIS TLIF: one level screws fixation using Wiltse approach at one side, the other side - percutaneously, one level decompression, correction of segmental deformity by performing vertebrotomy and then intervertebral fusion.




Primary Outcome Measures :
  1. Angle change at lumbar spine segment [ Time Frame: At 1 Day of hospital discharge or 14th day of hospital stay (depends on what event comes first) ]
    Angle between endplates at the treated level of lumbar spine


Secondary Outcome Measures :
  1. Improvement of Visual analog scale (VAS) back pain intensity [ Time Frame: 3, 6, 12 months ]

    To observe the improvement of VAS back pain as compared to baseline through follow-up terms.

    Visual Analogue Scale (VAS) - patient-reported pain intensity (0 - no pain, 10 - unbearable pain).


  2. Improvement of Visual analog scale (VAS) leg pain intensity [ Time Frame: 3, 6, 12 months ]

    To observe the improvement of VAS leg pain as compared to baseline through follow-up terms.

    Visual Analogue Scale (VAS) - patient-reported pain intensity (0 - no pain, 10 - unbearable pain).


  3. Improvement of Oswestry Disability Index (ODI) [ Time Frame: 3, 6, 12 months ]
    To observe the improvement of ODI as compared to baseline through follow-up terms Oswestry Disability Index - patient-reported physical and household activity. Minimum - 0 % (the best result, the patient has no limitations in physical activity). Maximum - 100% (the worst result, patient is not physically active at all).

  4. Fusion rate success [ Time Frame: 12 months ]

    To observe the Fusion rate (I, II, III or IV grade according to Tan).

    Grade I - complete fusion; Grade II - partial fusion; Grade III - unipolar pseudarthrosis; Grade IV - bipolar pseudarthrosis.


  5. Range of Motion [ Time Frame: At 1 Day of hospital discharge or 14th day of hospital stay depends on what event comes first, 12 months ]
    To observe the disc mobility at the treated level

  6. Sagittal balance parameters [ Time Frame: At 1 Day of hospital discharge or 14th day of hospital stay depends on what event comes first, 12 months ]
    To observe sagittal balance as compared to baseline

  7. Disc height [ Time Frame: At 1 Day of hospital discharge or 14th day of hospital stay depends on what event comes first, 12 months ]
    To observe disc height at the treated level as compared to baseline

  8. Blood loss [ Time Frame: Day of surgery ]
    Blood loss

  9. Surgery duration [ Time Frame: Day of surgery ]
    Surgery duration
