Radial carpal bone fractures - dorsal slab and chip fractures
XR of radial carpal bone fractures in greyhound?
carpal OA, radial carpal bone sclerosis (often chronic changes)
Dorsal slab fracture, oblique fissures?
Boxers
Aetiology of carpal fractures?
uknown, hypothesized due to incomplete ossification
Fatigue/Stress fractures
Treatment of os carpi radiale fractures?
Conservative - best
Lag screw, fragment removal - unpredictable
Not responding:

uncommon fractures
hyperextention trauma
tx: pancarpal arthrodesis
Metacarpal fractures?
Fracture of base - hyperextention injury
Subluxation of the antebraciocarpal joint?
more common than complete luxation
Fractured ulnar styloid process or rupture of collateral ligaments
Sx to treat - prosthetic ligament etc

Trauma
Treatment of radial carpal bone luxation?
Reduction of the bone, secure with screw or K-wire
Repair or medial collateral ligament
Good prognosis if treated promptly
If not -> Arthrodesis
