Case Study: MIS Cement Screw for L3 Compression Fracture

Vertebral compression fractures (VCFs) nyob rau hauv nruab nrab-hnub nyoog thiab cov neeg laus cov neeg mob feem ntau muaj ib tug ob peb sib tw: qhov yuav tsum tau rau tam sim ntawd structural restoration thiab qhov nyuaj ntawm kev ua tiav kev ruaj ntseg fixation nyob rau hauv osteoporotic los yog degenerative pob txha. Qhov kev tshawb fawb no tshawb nrhiav kev ua tiav daim ntawv thov kev ua tiav XC Medico MIS 5.5 System Cement Augmented Fenestrated Screw hauv chaw kho mob hauv Chile.

1. Kev soj ntsuam ua ntej kev ua haujlwm thiab kev tshawb fawb soj ntsuam

Ib tug poj niam muaj hnub nyoog 54 xyoo tau nthuav tawm nrog mob hnyav, mob nraub qaum qis tom qab lub caij nplooj zeeg me. Kev tshuaj xyuas lub cev qhia tau tias muaj kev sib haum xeeb hauv thaj tsam ntawm lub lumbar qaum thiab txwv tsis pub txav mus los.

Daim duab 1: Pre-operative imaging demonstrate L3 vertebral body compression fracture (kwv yees li 30% poob qhov siab) thiab cov cim qhia ntawm lumbar degeneration.

Kev kuaj pom thawj zaug (Daim duab 1) tau lees paub qhov L3 compression tawg uas muaj kwv yees li 30% ntawm qhov siab vertebral. Daim ntawv tshaj tawm kuj tau qhia txog kev hloov pauv ntawm lub lumbar degenerative , nrog rau cov pob txha hyperplasia ntawm lub vertebral margins thiab straightening ntawm physiological curvature. Vim tus neeg mob lub hnub nyoog thiab qhov degenerative ntawm cov pob txha, tsoos pedicle ntsia hlau fixation ntsib ib tug muaj kev pheej hmoo ntawm 'rub-tawm' los yog loosening.

2. Surgical Strategy: Vim li cas MIS Cement Augmentation?

Dr. Alejandro Silva tau xaiv rau Txoj Kev Kho Mob Tsawg Tsawg (MIS) kom txo qis cov nqaij mos raug mob thiab ua kom rov zoo. Qhov kev txiav txim siab siv XC Medico Cement Augmented Fenestrated Screw yog raws li ob yam tseem ceeb:

• Enhanced Anchoring: Tus tsim fenestrated tso cai rau kev txhaj tshuaj PMMA cement, tsim kom muaj 'pob txha-cement-ntsia hlau' sib xyaw uas ua rau muaj zog rub tawm hauv cov pob txha degenerative.
• MIS Compatibility: Lub 5.5mm system yog optimized rau percutaneous xa, txo cov ntshav poob thiab mob tom qab phais.

3. Intra-operative Execution thiab Post-operative Results

Cov txheej txheem tau ua raws li kev taw qhia fluoroscopic. XC Medico fenestrated screws tau muab tso rau ntawm L2 thiab L4, flanking lub pob txha pob txha L3. PMMA cement tau ua tib zoo txhaj tshuaj los ntawm lub hollow ntsia hlau shafts, ua kom pom kev sib cuam tshuam nrog cov pob txha nyob ib puag ncig.

Daim duab 2: Tom qab ua haujlwm CT qhia cov ntsia hlau hauv qhov chaw zoo tshaj plaws nrog cov cement sib npaug sib npaug ntawm qhov kev sib tw, muab kev ruaj ntseg tam sim ntawd.

Daim duab 3: Tag nrho cov txha nraub qaum rov qab. Kev kho sab hauv yog ruaj khov, thiab L3 qhov siab yog tswj xyuas.

Kev ua haujlwm tom qab CT thiab DR (Daim duab 2 & 3) tau lees paub tias qhov kev txhim kho sab hauv tau zoo tag nrho . Lub vertebral qhov siab tau khaws cia, thiab cov cement dispersion yog uniform. Tus neeg mob tau tshaj tawm txog 70% txo qhov mob nyob rau hauv 24 teev thiab tau txais kev txhawb nqa rau hnub thib ob tom qab kev phais.

4. Cov lus xaus

Kev sib koom tes ntawm cov kws tshaj lij phais mob ntawm Chilean pab pawg kho mob thiab XC Medico cov cuab yeej siv kho mob siab heev tau ua rau muaj txiaj ntsig zoo tshaj plaws. MIS 5.5 System Cement Augmented Fenestrated Screw ua pov thawj tias yog ib qho cuab yeej tseem ceeb rau cov kws kho mob txha caj qaum cuam tshuam nrog cov pob txha nyuaj hauv cov neeg mob uas muaj kev cuam tshuam cov pob txha zoo.
