5. Personal history
No underlying disease
No current medication
No smoking & alcohol
No drug & food allergy
6. Physical examination
HEENT : not pale conjunctiva ,
anicteric sclerae
Heart : full regular pulse, normal
S1,S2 , no murmur
Lung : no retraction , clear equally
Abdomen : soft , not tender
Neuro : E4V5M6 pupil 3 mm. RTLBE
7. Physical examination
Extremities :
Rt. Hand
No rotation, No wound, mild swelling
Tender at MCP 2-5th
No limit ROM of CMC&PIP jt.
Radial & ulnar pulses 2+
Capillary refill < 2 sec.
Sensory : intact
16. incidence
metacarpal fractures account for 40%
of all hand injuries
10-29 ages have highest incidence
metacarpal neck is most common site
of fracture
fifth metacarpal is most commonly
injured
17. Mechanism of injury
direct blow or rotational injury with
axial load
high energy injuries
25. CT indications
◦ inconclusive radiographs of CMC
fractures/dislocations
◦ multiple CMC dislocations
◦ complex metacarpal head fractures
26. General management
Non-operative : Immobilization
Indications
1. must be stable pattern
2. no rotational deformity
3. acceptable angulation & shortening
(see table)
30. Treatment - Metacarpal Shaft
Fractures
closed reduction percutaneous
pinning
◦ place antegrade through metacarpal
base or retrograde through collateral
recess
remove pins at 4 weeks
open reductions with lag screw
◦ can use multiple lag screws for long spiral
fractures
open reduction with dorsal plating
◦ works best for transverse fractures
Hinweis der Redaktion
ทุกนิ้วชี้ไปที่ scaphoid tubercle
Compartment syndrome associate with
closed injuries with multiple fractures or dislocations
crush injuries
inspect for open wounds and associated injuries
extensor tendon can be lacerated and retracted
dorsal wounds over metacarpal fractures are almost always open fractures
ต้องดู check motor, tendon ด้วย
deformity indicates location
deformity at metacarpal base may indicate CMC dislocation
shortening can be assessed by comparing contralateral hand
malrotation assessed by lining up fingernail in partial flexion and full flexion if possible, compare to contralateral side
neurovascular examination : dorsal/palmar digital nerve
test for radial and ulnar border two-point discrimination on the injured digit before any regional/hematoma block or attempted reduction
oblique radiographsfor evaluation of CMC joint and improved visualization of affected digit
30°pronated lateral
to see 4th and 5th CMC fx/dislocation
30°supinated view
to see 2nd and 3rd CMC fx/dislocation
Goal of tx
Restoration of articular anatomy
Correction of angulation and rotation deformity
Stabilize fx
