21. Metacarpal bone fracture
◦ divided into fractures of metacarpal
head, neck, shaft
◦ treatment based on which metacarpal is
involved and location of fracture
◦ acceptable angulation varies by location
◦ no degree of malrotation is acceptable
22. Epidemiology
incidence
▪ metacarpal fractures account for 40% of all
hand injuries
demographics
▪ men aged 10-29 have highest incidence of
metacarpal injuries
location
▪ metacarpal neck is most common site of
fracture
▪ fifth metacarpal is most commonly injured
23. Mechanism of injury
◦ direct blow to hand or rotational injury
with axial load
◦ high energy injuries (ie. automobile) may
result in multiple fractures
24. Associated injury
◦ wounds may indicate open fractures or
concomitant soft tissue injury
▪ tendon laceration
▪ neurovascular injury
◦ compartment syndrome
▪ closed injuries with multiple fractures or
dislocations
▪ crush injuries
25. Physical examination
inspect for open wounds and associated injuries
▪ fight wounds over MCP joint are open until proven
otherwise
▪ extensor tendon can be lacerated and retracted
▪ dorsal wounds over metacarpal fractures are almost
always open fractures
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
26. Physical examination
motor examination
▪ typically no motor deficits unless open wounds present
▪ check integrity of flexor/extensor tendons in presence
of open wounds
neurovascular examination
▪ dorsal wounds may affect dorsal sensory branch of
radial/ulnar nerve
▪ volar wounds can involve digital nerves
◦ test for radial and ulnar border two-point discrimination
on the injured digit before any regional/hematoma block or
attempted reduction
