Scaphoid Fracture
Scaphoid puas yog feem ntau cov pob txha pob txha, suav txog kwv yees li 70% ntawm tag nrho cov pob txha pob txha. Vim nws qhov tshwj xeeb anatomical txoj hauj lwm nyob rau hauv lub carpal pob txha npaj, tshiab scaphoid fractures yog nquag plam hauv kev kuaj mob. Ntxiv mus, qhov peculiar vascular mov ntawm scaphoid predisposes cov neeg mob rau cov teeb meem xws li nonunion, avascular necrosis (AVN), thiab carpal instability nyob rau tom qab theem. Clinically, scaphoid fractures yog ib qho nyuaj rau kev kho mob thiab feem ntau tawm hauv sequelae xws li mob dab teg, kev txwv ntau ntawm kev txav, thiab kev mob caj dab tom qab.
Lub luag haujlwm tshwj xeeb Anatomical ntawm Scaphoid
Lub scaphoid yog cov pob txha ntev tshaj plaws nyob rau hauv cov kab carpal proximal, zoo li lub nkoj me me (li no lub npe 'scaphoid'). Nws spans ntawm tus proximal thiab distal carpal kab, ua si lub luag hauj lwm tseem ceeb hauv stabilizing thiab txuas ob kab. Lub dab teg li qub, suav nrog flexion, txuas ntxiv, radial sib txawv, thiab ulnar sib txawv, txhua yam nyob ntawm kev sib koom tes ntawm scaphoid. Ib zaug puas lawm, biomechanics ntawm tag nrho lub dab teg yog cuam tshuam.
Fragile Vascular Supply
Tus scaphoid tau txais cov ntshav los ntawm cov ceg ntawm cov hlab ntsha radial, nkag mus los ntawm dorsal ridge thiab distal ncej:
Kwv yees li ntawm 70-80% ntawm cov ntshav ntws nkag los ntawm lub distal tubercle, ntws retrograde los txhawb nqa tus ncej proximal.
Tsuas yog ob peb ceg ncaj qha nkag mus rau tus ncej proximal.
Qhov cuam tshuam:
Qhov ze ntawm qhov tawg yog mus rau tus ncej proximal, qhov kev pheej hmoo ntawm vascular cuam tshuam ntau dua.
Thaum cov ntshav ntws cuam tshuam, qhov sib thooj ntawm qhov sib thooj yog qhov ua rau AVN thiab nonunion.
Common Injury Mechanism
Cov txheej txheem feem ntau ntawm kev raug mob yog lub caij nplooj zeeg mus rau ntawm txhais tes tawm (FOOSH) . Qhov kev raug mob tsis tu ncua no tau ua rau kev soj ntsuam thiab kev tshawb fawb ntau heev, thiab tau raug xa mus los ntawm lub ntsiab lus FOOSH.
Kev kuaj mob qeeb ntawm Scaphoid Fracture
Scaphoid pob txha feem ntau tshwm sim los ntawm FOOSH raug mob. Hauv cov mob me me, cov tsos mob yuav raug txwv rau qhov mob dab teg me ntsis, ua rau cov neeg mob tsis quav ntsej nrhiav kev kho mob. Txawm tias thaum X-rays (AP thiab lateral views) raug coj los, cov pob txha tawg yuav tsis pom tam sim ntawd. Cov neeg mob tuaj yeem rov qab tau ntau lub hlis tom qab nrog kev mob pob qij txha, thaum lub sijhawm ntsuas pom pom qhov mob scaphoid puas ntsoog - cuam tshuam qhov kev kuaj mob qeeb thiab ploj ntawm qhov kev kho kom zoo.
Cov lus pom zoo rau kev kuaj mob tseem ceeb:
X-ray duab yuav tsum tau ua rau txhua qhov kev raug mob dab teg, suav nrog kev pom scaphoid thaum xav tias pob txha.
Yog tias X-rays tsis zoo tab sis qhov tsis txaus ntseeg tseem nyob, yuav tsum siv immobilization, ua raws li rov ua dua tom qab 2 lub lis piam.
Thaum ntxov immobilization tuaj yeem ua ob qho kev kuaj mob thiab kho mob.
Kev kho mob xaiv
Sab nrauv Fixation
Cov pob txha tshiab, uas tsis yog nyob hauv qhov chaw tuaj yeem kho nrog immobilization. Txawm li cas los xij, fixation yuav tsum nruj kom zoo. Txheem plaster los yog resin splints yuav tsis tswj lub dab teg thiab forearm rotation, txo stability.
Plaster Cast Immobilization:
Long-arm ntiv tes xoo spica cam khwb cia:
Qhia rau qhov sib thooj ib feem peb ntawm pob txha (siab tshaj plaws AVN), kab ntsug / oblique fractures, thiab thawj zaug kuaj mob.
Immobilizes lub luj tshib ntawm 90 °, forearm, dab teg, thiab ntiv tes xoo.
Muab kev ruaj ntseg siab tshaj plaws los ntawm kev tshem tawm lub hauv pliaj tig.
Short-arm ntiv tes xoo spica cam khwb cia:
Haum rau kev puas tsuaj thib peb, tuberosity fractures, thiab ruaj khov nruab nrab lub duav pob txha (tom qab theem).
Muab kev nplij siab ntau dua tab sis tsis ruaj khov.
Sab hauv Fixation
Headless Compression Screw (Herbert Ntsia Hlau)
Tam sim no tus qauv kub rau scaphoid duav tawg.
Herbert Cannulated Compression Ntsia Hlau
Bevelled Cannulated Herbert Ntsia Hlau
Kirschner Hlau (K-xaim) Fixation
Ib txoj kev tseem ceeb tseem siv tau, feem ntau adjunctive.
Qhov zoo : yoog raws, pheej yig, cuam tshuam tsawg kawg ntawm vascularity.
Disadvantages : tsis ruaj khov, yuav tsum tau kho sab nraud, kev pheej hmoo kis kab mob, tshem tawm xav tau tom qab kho..
Indications : pediatric fractures, ib ntus fixation nyob rau hauv comminution, adjunct rau ntsia hlau fixation.
Cannulated Screw Ib nrab-xov
Cannulated Screw Ib nrab-xov
Scaphoid Tsis yog
Vim nws qhov tshwj xeeb vascular mov, scaphoid duav thiab proximal fractures yog nquag mus rau nonunion thiab AVN.
Kev kho mob : pob txha grafting (tsis-vascularized lossis vascularized) ua ke nrog kev kho sab hauv (Herbert ntsia hlau lossis K-xaim). Precise graft placement thiab smooth articular deg restoration yog ib qho tseem ceeb heev. Qee zaum, radial styloidectomy yuav tsum tau yog tias cov pob txha tseem ceeb cuam tshuam thaum lub dab teg.
