Terry Thomas yog ib tug neeg ua yeeb yam Askiv nto moo uas 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 xoo zoo li Terry Thomas qhov hniav sib nrug. Frankel hu qhov no ua "Terry Thomas sign," tseem hu ua "sparse tooth gap sign."
Kev Pom X-ray: Thaum muaj kev sib cais thiab kev rhuav ntawm scapholunate interosseous ligament, qhov pom anteroposterior ntawm lub dab teg lossis qhov pom coronal ntawm CT qhia txog qhov sib txawv ntawm cov pob txha scaphoid thiab lunate, zoo li qhov sib txawv ntawm cov hniav me me.
Kev Tshuaj Xyuas Cov Cim: Kev sib cais ntawm Scapholunate yog hom kev tsis ruaj khov ntawm lub dab teg feem ntau, tseem hu ua scaphoid rotary subluxation. Nws feem ntau yog tshwm sim los ntawm kev sib xyaw ua ke ntawm kev nthuav dav, kev hloov pauv ntawm ulnar, thiab cov zog supination siv rau sab ulnar palmar ntawm lub dab teg, ua rau cov leeg uas ruaj khov ntawm tus ncej proximal ntawm scaphoid tawg, ua rau muaj kev sib cais ntawm cov pob txha scaphoid thiab lunate. Cov leeg radial collateral thiab radioscaphocapitate ligament kuj tseem yuav raug rhuav.
Cov dej num rov ua dua, kev raug mob ntawm kev tuav thiab kev sib hloov, kev sib txuas ntawm cov leeg nqaij uas yug los, thiab qhov sib txawv ntawm ulnar kuj tseem cuam tshuam nrog kev sib cais ntawm scapholunate.
Kev Kuaj Duab: X-ray (nrog kev sib piv ob sab):
1. Qhov sib txawv ntawm Scapholunate gap > 2mm yog qhov ua rau muaj kev sib cais; yog tias > 5mm, nws tuaj yeem kuaj pom.
2. Lub cim ntiv nplhaib cortical scaphoid, nrog rau qhov deb ntawm ciam teb qis ntawm lub nplhaib thiab qhov sib koom ua ke ntawm qhov scaphoid yog < 7 hli.
3. Scaphoid luv dua.
4. Lub kaum sab xis scapholunate nce ntxiv: Feem ntau, nws yog 45-60°; lub kaum sab xis radiolunate > 20° qhia txog Dorsal Intercalated Segment Instability (DISI).
5. Lub cim Palmar "V": Ntawm qhov pom ntawm sab ntawm lub dab teg, cov npoo palmar ntawm cov pob txha metacarpal thiab radial tsim ib daim duab "C". Thaum muaj kev khoov tsis zoo ntawm scaphoid, nws cov npoo palmar sib tshuam nrog cov npoo palmar ntawm radial styloid, tsim ib daim duab "V".
