HAND SURGERY REVISION COURSE - QMC Nottingham Examination of the Wrist Mr P R Stuart FRCS Freeman Hospital Newcastle upon Tyne
OR (‘clunk, click every trip’)
Remember! • Not all that clicks or clunks is abnormal • most wrists don’t have ‘interesting’ instabilities • investigation of the wrist is clinical - investigations add little • knowledge of surface anatomy critical
Radial Side Styloid • De Quervain’s - Finkelstein (JBJS 12A; 509, 1930) • Wartenbergs • Intersection
Radial Side Snuffbox • swelling • articular / non-articular pain • scaphoid #’s • impingement, (malunion) • scapho-styloid OA
Dorsal Radial • Lister’s tubercle -> SL interval • occult ganglia • instability • Lunate - Keinbocks
Dorsal Central • Carpal boss • Extensor compartments • extensor manus brevis • tenosynovitis - moves with tendons • ganglia • PIN neuritis • lunate + capitate #’s
Dorsal Ulnar • DRUJ • compression, translation, piano key, dimple • TFC • Luno-triquetral, triquetro-hamate • Ulnar carpal impaction - pronation + UD
Dorsal Ulnar • ECU instability • supination, UD, flexion • 4th + 5th CMC OA • Mid-carpal instability
Palmar Radial • scaphoid - tuberosity #’s • STT - common, ganglia • 1st CMC • FCR tendonitis / trapezial ridge fractures • PCB neuroma
Palmar Ulnar • FCU tendonitis • Piso-triquetral OA - compression • Hook of Hamate - fist in UD • hypothenar hammer syndrome • Guyon’s canal compression • pillar pain
Provocative Testing • Scaphoid shift • Finger extension test • Midcarpal clunk • L-T shuck test • DRUJ • grind • pain at extremes
Lax, loose, wobbly or unstable • Like the shoulder there is a range of normal • most mid-carpal joints can be subluxed (pushed into VISI) • most clunks and abnormal movements can only be considered pathological if they occur during normal use and / or are painful • the ‘lax’ wrist is often painful without being ‘unstable’
Scaphoid shift - Watson’s test • Qualitative assessment of scaphoid instability • 10% normal wrists have positive test - take care!
Finger extension test • Resisted finger extension in full passive wrist flexion • +ve in DWS, SLAC, SLD, RSS, MCI, Kienbock’s
Articular - nonarticular • Periscaphoid synovitis, SLAC, instability, non-union
Catch-up clunk • Proximal row flicking suddenly from volar flexion to dorsiflexion • normal smooth transition from one to other under influence of capsular and intracarpal ligaments
