Terry Thomas yog tus neeg ua yeeb yam British nto moo paub txog nws qhov sib txawv ntawm nws cov hniav pem hauv ntej.
Hauv kev raug mob dab teg, muaj ib hom kev raug mob uas nws cov duab hluav taws xob zoo li Terry Thomas tus hniav sib txawv. Frankel hu ua "Terry Thomas kos npe," tseem hu ua "sparse tooth gap sign."
Radiographic tsos: Thaum muaj scapholunate dissociation thiab tearing ntawm scapholunate interosseous ligament, anteroposterior saib ntawm dab teg los yog coronal saib ntawm CT qhia tau hais tias muaj kev sib txawv ntawm cov pob txha scaphoid thiab lunate, zoo li cov hniav sib txawv.
Kev Ntsuam Xyuas Kos Npe: Scapholunate dissociation yog hom kev tsis sib xws ntawm dab teg, tseem hu ua scaphoid rotary subluxation. Nws feem ntau tshwm sim los ntawm kev sib txuas ntawm kev sib txuas, ulnar sib txawv, thiab supination rog siv rau ulnar palmar sab ntawm lub dab teg, uas ua rau muaj kev sib tsoo ntawm ligaments uas stabilize tus ncej ntawm tus scaphoid, ua rau kev sib cais ntawm cov pob txha scaphoid thiab lunate. . Cov radial collateral ligament thiab radioscaphocapitate ligament kuj yuav raug torn.
Kev ua ub ua no rov ua dua, tuav thiab sib hloov kev raug mob, congenital ligament laxity, thiab tsis zoo ulnar variance kuj cuam tshuam nrog scapholunate dissociation.
Kev kuaj pom: X-ray (nrog kev sib piv ob sab):
1. Scapholunate qhov sib txawv> 2mm yog qhov tsis txaus ntseeg rau kev sib cais; Yog tias> 5mm, nws tuaj yeem kuaj tau.
2. Scaphoid cortical nplhaib kos npe, nrog qhov kev ncua deb ntawm tus ciam teb qis ntawm lub nplhaib thiab qhov sib koom ua ke ntawm qhov scaphoid yog <7 hli.
3. Scaphoid luv luv.
4. Nce scapholunate lub kaum sab xis: Feem ntau, nws yog 45-60 °; lub kaum sab xis radiolunate> 20 ° qhia tias Dorsal Intercalated Segment Instability (DISI).
5. Palmar "V" kos npe: Ntawm qhov ib txwm pom ntawm lub dab teg, cov npoo ntawm cov pob txha metacarpal thiab radial tsim ib qho "C". Thaum muaj qhov txawv txav ntawm lub scaphoid, nws cov ntug palmar cuam tshuam nrog lub palmar ntug ntawm radial styloid, tsim "V" zoo.
