Postoperative recovery chak zawk

Damdawi ina awm rei lote chu:

damlo tam zawk chu operation hnu darkar 24-48 chhungin chhuahtir an ni a, traditional open surgery-ah chuan ni 3-5 chhungin chhuahtir an ni thung.

Hma lama kal theihna:

Natna tlem zawk leh taksa ruh venna tha zawk hian damlote chu an nitin hnathawhnaah rang zawkin an kir leh thei a ni.

Biomechanical hmanga tihchangtlun a ni

Material hmanna thar:

eg 3D printed titanium alloys, PEEK (polyether ether ketone) materials hmanga ruh nena inhnaih modulus of elasticity neih theihna tur leh stress masking tihziaawmna tur.

Dynamic stabilization system hrang hrangte chu:

implant thenkhat (eg Dynesys, Coflex) hian spinal mobility a humhim a, adjacent segment degeneration hlauhawmna a ti tlem bawk.

Indication tihzauh a ni

Spinal pathology hrang hrang degenerative disc disease, lumbar spinal stenosis, mild spondylolisthesis leh vertebral fractures te a huam a ni.

临床案列 tih hi a ni

A hnuaia tarlan te hi tun hnaia research case aiawhtu (representative research case) te an ni:

1. Lumbar spine fusion (TLIF) chungchanga randomized controlled trial neih a ni ang.

Zirna design: 1.1.

prospective multicenter RCT (2022) chuan MIS-TLIF (minimally invasive) leh open TLIF te chu a khaikhin a.

Sample lian leh te:

Damlo 120 chu single-segment degenerative lumbar spine disease vei an ni.

Rahchhuah:

Surgery hun chhung:

MIS group-ah chuan a rei deuh (mean 150 min vs. 130 min), mahse 60% in thisen chhuah a tlem zawk (<100 ml vs. 250 ml).

Operation hnua natna: 1.1.

MIS group-ah hian operation hnu kar 1-ah VAS score 50% a tlahniam a, thla 3 hnuah pawh group pahnih inkarah danglamna lian tham a awm lo.

Fusion rate chu:

Kum 1 hnua CT-ah chuan group pahnihah hian >90% fusion rate a awm tih hmuhchhuah a ni.

Harsatna awm thei:

MIS group-ah hri kai zat chu 2% a ni a, open group-ah chuan 8% a ni thung.

2. Hun rei tak chhunga dynamic stabilization system (Coflex) chungchang zirchianna .

Zirna design: 1.1.

European kum 5 chhunga zirchianna (2021)-a lumbar spinal stenosis enkawlna atana Coflex implantation endikna.

Sample lian leh te:

damlo 80 an awm.

RAHCHHUAK:

Hnathawh lama hmasawnna:

ODI (dysfunction index) chu baseline-a point 45 aṭanga kum 5-ah point 20-ah a tlahniam a ni.

NEIGHBORING SECTION THIL TIH LO AWM DAN: 1.1.

Damlo 12% chauhvin adjacent segment problem an nei a, chu chu conventional fusion (~30%) aiin a hniam zawk hle.

Reoperation rate: 1.1.

cumulative 5-year reoperation rate 8% a ni a, a chhan ber chu implant loosening (4%) emaw symptomatic recurrence emaw vang a ni.

3. Robot hmanga MIS implant hmanga multicenter zirchianna

Zirna design: 1.1.

retrospective study kum 2023-a tihchhuah, Mazor robotic puihna hmanga MIS screw dahna result thlirletna a ni.

Sample lian leh te:

Screw dahna 500 (thoracolumbar spine) a awm bawk.

Rahchhuah:

A dikna: 1.1.

Screw position 98.6% chu a lungawithlak hle (Gertzbein-Robbins grading A/B).

Harsatna awm thei:

nerve root injury rate chu 0.4% a ni a, freehand placement pangngaiah chuan 3-5% a ni thung.
